Self-Employed Income Simulator by Umalis

Planning your take-home income in France starts with clear numbers. About 12.6% of the French workforce is independent (OECD 2021), and many professionals need a practical way to turn invoices into usable pay.

This guide shows how to estimate net income after social security charges, contributions, and tax. Use the Umalis income simulator as your control panel: it converts gross turnover into a reliable net projection for planning. Try the simulator at Umalis income simulator and switch to English navigation at Umalis English site.

We focus on current rules, general scheme coverage, unified declarations and 2025 references where relevant. You will learn to separate turnover, taxable professional income, and true take-home pay—where most forecasting errors begin.

We cover different statuses (micro-entrepreneur, company forms, and portage salarial) and protection topics like health insurance, sickness benefits, and retirement so your net income is paired with security. Run a first simulation early, then refine as you learn ceilings, minimums, and first-year rules.

Key Takeaways

• Use the Umalis simulator to convert invoices into a trusted net income estimate.

Why an income simulator matters when you’re self-employed in France

Forecasting your real take-home is essential when your pay depends on invoices, not a regular payroll.

An income simulator helps you convert a billed amount into net monthly cash by applying current contribution rules and an understandable effective rate.

Estimating net income after social security contributions and income tax

Enter turnover, choose a status, and the tool shows contributions, income tax estimates, and the resulting net income.

Planning cash flow when income varies month to month

Income often comes irregularly. A simulator highlights timing mismatches: payment dates, quarterly contributions, and catch-up tax payments later in the year.

Comparing statuses and contracts before you commit

Run scenarios for different legal forms and a proposed contract. This prevents surprises like turnover limits or higher costs for certain activities.

• Simulate best-case, expected, and conservative scenarios to protect rent or loan commitments.
• Use outputs to negotiate daily rates and payment terms.

Scenario	Gross amount (€)	Estimated contributions (€)	Estimated net income (€)
Conservative	20,000	6,000	12,000
Expected	35,000	10,500	24,500
Best-case	50,000	15,000	35,000

What “self-employed” means and how it’s defined for tax and social security

Defining who legally works for themselves matters for taxes, social protection, and how you plan income.

Practical definition: a person who finds their own work, invoices clients, and declares the income on the required tax return. Tax authorities look at whether the activity is profitable and regularly taxed.

How it differs from entrepreneurship and startups

An entrepreneur often aims to grow a business and hire people. A startup targets scale and external investment. By contrast, an independent professional typically creates a sustainable job for themselves without immediate plans to employ others.

When independence becomes disguised employment

Authorities assess reality, not labels. A contract calling someone an independent worker does not prevent reclassification if the person depends on one client, follows strict hours, or lacks financial risk.

Indicator	Suggests independence	Suggests employment
Clients	Multiple clients	Single dominant client
Control	Sets own schedule	Subject to employer hours
Risk	Assumes financial risk	Guaranteed salary

Practical tip: Keep contracts, deliverables, and client emails to prove autonomy. Misclassification can change contributions, protections, and your true net income. For more on advantages and choices, see benefits of self-employment.

How the French social security system for self-employed workers is organized today

Clarity about who does what helps you plan income and protection. Since the RSI transition ended in early 2020, most independent professionals are attached to the general scheme. Specific rules and funds still apply depending on profession and status.

After the RSI: coverage under the general scheme since 2020

RSI was eliminated by a 2018 law and fully integrated into the general scheme by 2020. Today, basic health and retirement coverage flows through the general system while some professions keep dedicated funds.

Who does what: quick roles

• Urssaf — collects contributions and handles declarations.
• CPAM — manages health reimbursements and medical services.
• Carsat / CNAV / CGSS — administer basic retirement for many workers.
• CNAVPL, CIPAV, CNBF — oversee profession-specific retirement and disability-death schemes for regulated activities.

Who is considered a self-employed worker under French rules

Categories include craftsmen, shopkeepers, certain company executives and partners, contributing spouses, auto-entrepreneurs, and private-practice professionals. You can also combine salaried work with an independent activity; this dual status affects your protection layering and forecasting.

Why this matters for your simulator: the managing body determines contribution types, ceilings, and benefit rules. If you are unsure which fund covers you, verify it before relying on long-term projections. Knowing the correct contact points speeds up access to deadlines, payment portals, and accurate information.

Social security contributions: what you pay, who you pay, and what you get

Understanding which contributions you owe clarifies what remains in your pocket each month. Urssaf collects most levies and forwards them to the relevant schemes that fund health, retirement, and family protection.

Mandatory contribution blocks

The main ongoing blocks typically included are:

• Health–maternity: basic care and reimbursements.
• Daily sickness / maternity allowances: income support when you cannot work.
• Retirement: basic pension accrual.
• Disability–death: protection for incapacity and survivors.
• Family benefits: child and household support funds.
• CSG‑CRDS: social levies that finance multiple schemes.
• Training contribution: funds professional training rights.

How contributions are calculated

Contributions are based on taxable professional income, not gross turnover. This distinction matters: turnover can overstate the taxable base or hide deductible costs.

Pass note: ceilings and some benefit caps reference the PASS, set at €47,100 in 2025. Know this amount when you model limits.

Minimums, unemployment, and planning

Even in low or negative years, certain minimum contributions can apply. “No profit” does not always mean “no pay social” obligations.

Most independent workers do not pay regular unemployment contributions and therefore lack statutory unemployment benefits. If job-loss protection matters, consider private coverage and keep an emergency buffer in your cash plan.

« Model on taxable income, not turnover, to get a reliable net projection. »

For specifics on rates and examples, see our detailed guide on social charges. Use the simulator input that matches your regime: turnover for micro, taxable income for other schemes.

Micro-entrepreneur and auto-entrepreneur: simplified contributions and turnover limits

Micro status lets you pay predictable charges on turnover and keeps administration light. It is popular because percentages are fixed and easy to forecast for cash flow.

Turnover thresholds and what happens if you exceed them

Key limits (2024, declared in 2025): €188,700 for sales/accommodation/food and €77,700 for services. Exceeding a limit can trigger a change of regime, VAT obligations, and more complex accounting.

Typical micro-social contribution rates by activity

• Sales / commerce: 12.3% rate.
• Contracting / building: 21.2% rate.
• Regulated liberal: 23.2% (22.20% if CIPAV-managed).
• Unregulated liberal: 24.6% rate.

Declarations, payments and the training contribution

Declare turnover monthly or quarterly via autoentrepreneur.urssaf.fr. Regular declarations help you smooth cash flow despite uneven client payments.

The training contribution is a small percentage of turnover (0.25% for shopkeepers/private practice, 0.30% for craftsmen) and funds professional training rights.

Guidance: Micro is efficient but may not suit activities with large costs or fast growth. We advise simulating both staying under the caps and years when you exceed the limit to avoid sudden net-income shocks.

Income tax for the self-employed: how it connects to your declarations and cash planning

How and when you declare earnings changes the moment money becomes spendable in your personal account. That timing matters because French tax rules add freelance income to household income for the annual return.

Unified declaration since 2021

The DSI was eliminated in 2021. Now social contributions and income tax information are declared via a single form on impots.gouv.fr (DSFU). This reduces duplicate filings but makes correct reporting essential.

Pay-as-you-go and timing mismatches

Pay-as-you-go options smooth surprises by spreading tax across the year. They work well if you keep monthly discipline.

Remember: you may earn in January, declare later, and pay months afterward. That gap is where « I earned it » diverges from « I can spend it. »

Practical steps to protect cash flow

• Micro-entrepreneurs still declare turnover to Urssaf monthly or quarterly, while tax on that income is handled via the unified return.
• Open a dedicated tax sub-account and set aside a percentage after each invoice.
• Use the simulator as an input to monthly budgets, not a one-off curiosity.

« Model your tax timing alongside contributions to avoid cash surprises. »

Choosing the right legal and working setup for your activity

Your legal and working setup determines administrative load, liability exposure, and net results.

Micro-entreprise: speed and simplicity

Advantages: quick registration and simple declarations. It suits many solo activities and keeps admin light.

Trade-offs: turnover caps and limited expense deductions can lower net income when costs are high.

EURL and SASU: separate personal and business assets

These company forms create a distinct legal entity. They limit personal liability and help protect assets.

They add administrative steps but give more options for tax planning and insurance choices.

Portage salarial: work independently with employee protections

Portage makes you an employee of an umbrella company. You keep client autonomy while gaining payslips and benefits.

Fees typically run 7–10% of invoiced revenue, which changes net outcomes compared with acting through a company.

When a company structure becomes necessary

Higher-risk sectors or rapid revenue growth often justify forming a company early. Liability, insurance, and client expectations matter more than small tax differences.

Option	Operational change	Financial impact	Best for
Micro-entreprise	Minimal admin	Fixed contribution rates, caps	Low-cost solo activities
EURL / SASU	Separate company, formal accounts	More deductible costs, liability protection	Higher revenue, risk exposure
Portage salarial	Umbrella company handles payroll	Fees 7–10%, employee protections	Consultants wanting stability
Hybrid / other	Custom setups	Varied	Complex activities or mixed income

« Model net income under at least two setups before you commit. »

Starting out: first-year and second-year contribution rules you need to model

Starting a business often means the first year’s charges are estimates, not final bills. Administrations apply provisional flat amounts until annual income is declared. This creates timing differences you should model from day one.

Provisional flat amounts when annual income isn’t known

At launch, Urssaf may set a flat provisional amount to collect early contributions. Later, the system recalculates based on actual income and issues catch-up payments or refunds.

Practical note: keep a cash buffer to absorb possible adjustments and avoid surprise debt.

Acre exemption: eligibility, duration, and income bands

Acre can reduce some charges for the first 12 months. Eligibility typically targets new entrepreneurs meeting activity and registration criteria.

• Below €35,325 — total exemption for specified lines.
• €35,325–€47,100 — partial, degressive relief.
• Above €47,100 — no exemption.

Remember: Acre may not cover every line. Read exemptions carefully when you project net pay and the applicable rate per contribution.

Adjusting provisional contributions when income changes

You can request an early adjustment if incomes rise or fall. Proactive changes reduce year-end shocks and smooth cash flow across the second year.

We advise building two forecasts: one under the provisional schedule and one after recalculation. Use both to plan monthly budgets and reserve the right amount for taxes and social security contributions.

Item	Provisional (startup)	After declaration
Collection method	Flat provisional amount	Recalculated on actual income
Acre effect	Possible exemption (12 months)	Total/partial/none by band
Cash impact	Immediate pay social outflow	Possible refund or catch-up

For practical examples on filing and deductions that affect these schedules, see our guide on taxes, filing and deductions. Anticipation and two simple scenarios make these first years manageable.

Benefits tied to contributions: health coverage, daily sickness benefits, and parental rights

Contributions are not only a cost: they buy access to health services, daily allowances, and pension rights that protect your income when life changes.

Puma and CPAM reimbursements

Once affiliated under Puma, you gain coverage aligned with the general scheme. CPAM handles reimbursements for care, prescriptions, and medical acts.

Practical note: correct affiliation and timely declarations ensure you get the expected reimbursements and avoid delays in services.

Daily sickness benefits: eligibility and calculation

To qualify you need 12 months of uninterrupted membership. Benefits start on day 4 after a 3-day waiting period.

Payment equals 1/730 of the average yearly earned income over the last three calendar years. Caps apply: PASS is €47,100 in 2025 and the general max is €64.52/day.

If average income is under €4,383.20, daily benefits may be zero. Regulated incomes via CIPAV are considered up to 3×PASS with a higher cap (€193.56/day).

Maternity, paternity and timely declarations

Declare births and maternity/paternity events promptly to protect entitlements. Timely reporting preserves benefit levels and waiting-period exemptions.

Retirement basics

Retirement rights accrue under Carsat/CNAV for most workers. Some professions use CNAVPL or CNBF—check your fund to verify rules and contribution-to-right conversion.

« Benefits are part of your net value: model them alongside take-home pay. »

Insurance and protection: what to add beyond mandatory social security

Protection decisions—what you buy beyond statutory cover—shape how resilient your income really is.

Complementary health cover (mutuelle)

Mutuelle reduces out-of-pocket costs that CPAM does not reimburse. For frequent care or family coverage, this premium is a predictable budget line that smooths monthly cash flow.

Professional liability

Responsabilité civile professionnelle protects your business against client claims. In some sectors it is contractually required. Without it, a single claim can wipe out savings and interrupt work.

Job-loss alternatives

Most independent profiles do not pay standard unemployment contributions. Private job-loss insurance and an emergency reserve are realistic ways to cover gaps in income and benefits.

When you use the Umalis simulator, include essential premiums in your net comparison. Model scenarios with and without key covers so you see real take-home pay after protection costs.

Decision order: insure catastrophic risks first (liability, major health gaps), then add smaller covers based on activity and client contracts. We recommend balancing cost and continuity: good protection preserves both income and business reputation.

How to use the Umalis self-employed income simulator to estimate take-home pay

Begin with concrete inputs—your legal status, activity type, and an expected gross billing—to get a meaningful projection. The simulator turns these facts into clear figures you can act on.

Key inputs that change results

Choose status, specify activity category, and enter your billing amount. Small changes to status or cadence can move the effective rate significantly.

Reading the dashboard output

The tool shows estimated contributions, projected income tax, and social security contributions. It also gives net income and an effective rate so you can compare options quickly.

Per year vs monthly projections

Run a per year projection for strategy, then translate it into monthly figures to match invoices and bills. That reveals timing gaps and helps protect cash flow.

Run three scenarios

Simulate conservative, expected, and high‑revenue years to stress‑test commitments before signing a contract. Use results to set aside a dedicated account for contributions and tax.

What to prepare

• Last year’s numbers (if any).
• Current contract terms and payment delays.
• Expected start dates and project gaps.

Real-world scenarios the simulator should help you test before signing a contract

Test practical contract scenarios to see how pay and protections shift in real life. Use the simulator to compare net income and benefit changes under each option. This reveals gaps that affect monthly cash and long-term security.

Switching from employee to freelance: protections and pay

When you leave an employee role, unemployment cover and paid leave expectations change. You gain rate flexibility, but you often lose statutory unemployment benefits and paid holidays.

Use the simulator to set a target daily rate that compensates for lost benefits, extra insurance costs, and admin time. Model gross-to-net outcomes and the resulting take-home income.

Freelancing as a secondary activity

Additional freelance income is added to household income for tax. Contributions still apply and can reduce the true net gain.

Simulate small, regular earnings and one-off projects to see tax effects and whether the extra work is worth the marginal income after charges.

Crossing thresholds and benefit cliffs

Test scenarios that approach micro turnover limits and the Pass ceiling. Crossing these limits can change your status mid-year and trigger different contribution rules.

Also check low-income bands: some daily benefits fall sharply under minimum averages. The simulator helps spot these benefit cliffs before you commit.

Scenario	What to test	Key impact
Employee → independent	Compare net pay, lost unemployment, insurance costs	Higher gross needed to match former take-home
Secondary freelance work	Household tax addition, contribution overlap	Lower marginal net after charges
Near micro limit	Turnover crossing, VAT and regime change	Administrative burden and different rates
Pass/benefit cliff	Average income tests for daily benefits	Sudden reduction in entitlements

Protective checklist before signing

• Confirm status compatibility with your planned contract and activity.
• Validate expected net income using conservative and expected scenarios.
• Ensure a cash buffer covers contribution and tax timing differences.
• Model late payments, monthly variability, and whether a contract pushes you past a limit.

« Use the simulator not only to forecast, but to negotiate rates and control risk. »

Administrative essentials that impact your net income forecasts

Administrative steps shape how much cash you actually keep after every invoice. Missing formalities can cause fines, slow payments, or VAT bills that shrink your forecasted net. Treat admin as a predictable cost line in your model.

Registration and the identifiers you need

Practical SIREN and SIRET information

When you register via Urssaf, INSEE issues your SIREN and SIRET numbers. Use the SIREN as the company number and the SIRET on invoices. If the SIRET is pending, the allowed interim wording is “SIRET en cours d’attribution”.

Invoicing, VAT mentions and common mistakes

Invoice essentials to reduce disputes

Include date, service description, totals, client details, your SIREN, payment terms, and your bank account. Clear invoices speed payments and protect your cash flow.

VAT status and its cash effect

If you do not charge VAT, add “TVA non applicable, article 293 B du CGI”. VAT affects pricing and timing: it is not yours—yet it changes the cash you must collect and report.

Bank account expectations for micro-entrepreneurs

Micro-entrepreneurs with revenue over €10,000/year need a separate business account. Separation helps you reserve funds for contributions and tax and keeps bookkeeping simple.

« Admin choices — from VAT form to payment terms — change the real net you can spend. »

Common mistakes when projecting self-employed income and how to avoid them

A common trap is equating billed revenue with the money you can actually use each month. Treat turnover, taxable income, and take‑home pay as separate figures when you plan. Confusing them leads to under-saving and cash pressure.

Confusing turnover, taxable income, and take‑home pay

Turnover is total billed amount. Taxable income is turnover minus allowable costs and regime adjustments.

Take‑home pay is what remains after tax, contributions, and any insurance premiums. Always model all three to set realistic monthly targets.

Ignoring contribution recalculations and timing of catch‑up payments

Authorities recalculate contributions after you file. That can trigger catch‑up amounts months later.

Plan for potential reversals or additional invoices by keeping a reserve equal to a percentage of billed income and reviewing forecasts quarterly.

Overlooking low‑income years and minimum contribution rules

Even in weak or negative years you may still must pay certain minimum contributions. These floor costs affect liquidity.

Model a conservative scenario that includes minimums for the relevant years so you never short funds for mandatory lines.

Assuming you have the same unemployment protections as an employee

Most independents do not pay unemployment contributions and therefore lack standard unemployment cover. Do not assume employee‑style protection.

Consider private job‑loss insurance, portage options, or a dedicated emergency fund to replace that missing safety net.

• Set aside a monthly percentage of each invoice for tax and contributions.
• Perform a quarterly review and adjust for actual receipts and declared amounts.
• Keep clear documentation to protect deductible costs and avoid misclassification.

« These mistakes are common; with a simple routine you can turn uncertainty into predictable cash flow. »

For practical steps and a guided simulation, see our short guide on planning take‑home income. We recommend a repeatable forecast routine to protect both income and security.

Conclusion

Closing the gap between billed amounts and usable cash requires modeling timing, charges, and protections.

Confident independence in France comes from understanding social security, contributions timing, and the benefits that follow payment. Net income is a system outcome: status, activity type, ceilings like the PASS, first‑year rules, and accurate admin all shape what you take home.

FAQ

What is the Umalis Self-Employed Income Simulator?

The simulator is an online tool that estimates your take-home pay by combining social security contributions, income tax, and other mandatory charges based on your chosen status and activity in France.

Why does an income simulator matter when you work independently in France?

It helps you estimate net income after social security contributions and income tax, plan cash flow when income varies month to month, and compare statuses and contracts before you commit to a legal form or client engagement.

How is “self-employed” defined for tax and social security purposes?

For French rules, it generally means you run professional activity outside salaried employment, declare professional income, and depend on specific schemes for contributions and benefits rather than the standard employee payroll system.

What is the difference between self-employment, entrepreneurship, and running a startup?

The label influences scale and structure. A solo professional often uses simplified regimes, an entrepreneur may form a company and hire staff, and startups prioritize growth and investment—each choice changes taxation, social contributions, and legal risk.

What is disguised employment and why does it matter?

Disguised employment occurs when an ostensibly independent contractor operates like an employee. Authorities may reclassify the relationship, triggering back payments for social security contributions and penalties for non-compliance.

How is the French social security system organized for independent workers today?

Since 2020 many independent contributors are covered by the general scheme. Urssaf collects contributions, CPAM handles health reimbursements, Carsat/CNAV manage retirement for salaried regimes, while CNAVPL, CIPAV, or CNBF may be involved for certain professions.

Who collects which contributions (Urssaf, CPAM, etc.)?

Urssaf collects social contributions and sends records to relevant bodies. CPAM manages healthcare reimbursements. Pension and professional-fund responsibilities depend on your activity and may involve CNAVPL, CIPAV, or CNBF for specific professions.

Which contribution types are mandatory for independent workers?

Mandatory contributions typically include health insurance, family benefits, basic and supplementary pensions, professional training, and CSG/CRDS taxes. Exact composition depends on status and activity type.

How are contributions calculated from taxable professional income?

Contributions are generally a percentage of your taxable professional income or turnover, with specific rates varying by regime. Some schemes use flat provisional amounts early on, later adjusted to actual income.

What is the annual Social Security ceiling (Pass) and why is it important?

The PASS defines upper limits for certain contribution and benefit calculations. It influences contribution bases and ceilings for pensions and social charges; crossing multiples of the PASS may change contribution rules.

What happens if I have very low or negative income?

Minimum contributions can apply in low-income years. You may qualify for reductions, partial exemptions, or specific support measures, but some minimum base contributions—especially for healthcare or training—can still be due.

Do independent workers pay unemployment contributions?

Typically, independent professionals do not pay standard unemployment contributions and therefore do not automatically receive unemployment benefits, though private job-loss insurance exists as an alternative.

What are the turnover thresholds for micro-entrepreneur regimes?

Thresholds differ by activity—sales of goods have higher caps than service activities. Exceeding these thresholds requires moving to a different regime and can change how you calculate contributions and VAT treatment.

What are the typical micro-social contribution rates by activity?

Rates vary by sector: sales, services, and liberal activities each have specific percentage rates applied to turnover. Those rates are simplified and include social charges and family benefits; exact percentages depend on current legislation.

How do I declare and pay micro-entrepreneur contributions?

Declarations and payments are made monthly or quarterly via Urssaf’s online portal. You report turnover and the system calculates the contributions due according to your activity-specific rate.

What is the training contribution for micro-entrepreneurs?

The formation professionnelle charge funds professional training rights. It’s a small percentage of turnover paid alongside social contributions and gives access to continuing education programs.

How did the unified tax declaration replace previous systems like the DSI?

The unified declaration centralizes income reporting for tax and social calculations, simplifying administrative steps. It aligns taxable professional income reporting with income tax procedures and helps with pay-as-you-go mechanisms.

How does pay-as-you-go taxation affect cash flow?

Pay-as-you-go spreads income tax payments across the year, but timing mismatches between when you invoice and when taxes are debited can create cash-flow pressure. Modeling monthly vs annual scenarios helps anticipate gaps.

How is freelance income added to household income for tax purposes?

Professional income is combined with other household income on the tax return. This aggregation determines your tax bracket and household tax rate, affecting the final income tax due.

When should I choose micro-entreprise versus EURL or SASU?

Choose micro-entreprise for simplicity and low turnover. EURL or SASU are better when you need liability separation, anticipate higher revenues, want to optimize social charges or retain earnings in a company structure.

What is portage salarial and when is it appropriate?

Portage salarial lets you operate like an independent while becoming an employee of a portage company. It suits professionals who want payroll protections (unemployment, simplified admin) without creating a company.

When does forming a company become necessary?

A company structure becomes necessary when revenue, client risk, or investment needs grow, when you want to separate personal assets from business liabilities, or when tax and social optimization require it.

How are first-year and second-year contribution rules different?

Initial years often use provisional flat amounts or reduced rates to ease new activity. These are later recalculated based on actual income, possibly creating catch-up payments or adjustments in year two.

What is the ACRE exemption and who qualifies?

ACRE offers partial exemption from social contributions for eligible new business creators for a limited period. Eligibility depends on your situation and income bands; the exemption amount phases out as revenue grows.

How do provisional contributions adjust when my income changes?

You can request adjustments to provisional contributions as soon as your income forecast changes. Urssaf will recalculate payments, reducing the risk of large end-of-year reconciliations.

What benefits are tied to paying contributions (health, sickness, parental rights)?

Contributions fund healthcare coverage (PUMA/CPAM reimbursements), daily sickness benefits, maternity/paternity rights, and future pensions. Entitlement levels depend on contributions and declared income.

How are daily sickness benefits calculated and when do they start?

Daily sickness indemnities depend on average declared income and a waiting period applies. Eligibility and amounts differ by regime; accurate income declarations help secure appropriate compensation.

What do I need to declare to protect maternity and paternity entitlements?

Timely and accurate declaration of professional income and continuous contribution payments are essential. Early planning and proper registration with CPAM preserve rights and simplify benefit claims.

How does retirement work for independent professionals?

Retirement depends on the general scheme and, for some professions, specific pension funds. Your pension base is calculated from declared professional income and contributions paid across your career.

What additional insurance should I consider beyond mandatory coverage?

Consider complementary health insurance (mutuelle) to reduce out-of-pocket costs, professional liability insurance to cover claims, and private job-loss coverage if you want income protection similar to unemployment benefits.

Is professional liability insurance always required?

Some sectors mandate professional liability coverage by law or by client contracts. Even when not mandatory, it protects your activity against claims and is often advised for client-facing professions.

How do I use the Umalis simulator to estimate take-home pay?

Provide inputs such as status, activity type, billing amounts, prior income, and declaration frequency. The tool outputs contributions, taxes, net income, and an effective rate to help you plan.

Which inputs most change the simulator results?

Status, activity type, billing amount, and whether you opt for monthly or quarterly declarations significantly affect results. Including other household income also changes tax outcomes.

Should I model projections per year or monthly?

Model both. Annual projections show total tax and contribution exposure, while monthly projections reveal cash-flow timing and help plan for seasonal or irregular invoices.

What scenarios should I run before signing a contract?

Test switching from employee to independent, working freelance alongside salaried roles, and crossing thresholds such as turnover caps and Pass ceilings to understand benefit cliffs and tax shifts.

What administrative details impact net income forecasts?

Registration, SIREN/SIRET numbers for invoicing, correct VAT mentions, and using a business bank account (required for some micro-entrepreneurs above thresholds) all affect compliance and net results.

What common mistakes should I avoid when projecting income?

Don’t confuse turnover with taxable income or take-home pay. Anticipate contribution recalculations and catch-up payments, account for minimum contributions in low-income years, and don’t assume employee-level unemployment protections.

How can I prepare before using the simulator?

Gather prior income figures, current contracts, expected billing cadence, chosen legal status, and planned declaration frequency. This ensures realistic scenarios and more reliable forecasts.
