How Much Should You Set Aside for Taxes and Contributions as a Self-Employed Person?

Quick answer. You should set aside between 30% and 50% of your turnover depending on your structure (flat-rate sole proprietor, real-basis self-employed, SARL managing partner). This covers three items: social contributions (12.3% to 25.6% of turnover under the flat-rate regime), income tax (based on your marginal rate), and VAT payable when you are VAT-liable. A dedicated savings account spares you cash flow crises.

In 2026, three developments make provisioning essential for every self-employed person in France. First, the flat-rate social contribution rate for liberal professions (BNC) has continued to rise (25.6% as of 1 January 2026), increasing the contribution burden. Second, income tax is collected on a regular schedule (monthly or quarterly via contemporaneous withholding), requiring anticipation. Third, mandatory digital social declarations make every payment traceable and non-negotiable—URSSAF recovers arrears quickly.

At Hayot Expertise, we regularly see business owners shocked by an URSSAF reconciliation of several thousand euros they had not anticipated in the first months. A simple provision of 30% to 45% in a dedicated savings account would have avoided this shock.

A self-employed individual bears three categories of mandatory outflows that are not freely available business funds: social contributions, income tax (or corporate income tax depending on the chosen form), and VAT collected for remittance.

1. Mandatory social contributions (URSSAF). These fund social protection: health-maternity, disability, base and supplementary pensions. The rate varies by status and activity, calculated on turnover (flat-rate regime) or net profit (real basis).

2. Income tax (or corporate income tax). If you are a flat-rate sole proprietor with the optional flat-rate withholding, tax is withheld at a fixed rate (1% to 2.2% of turnover depending on activity). Otherwise, income tax is computed on profit and collected via contemporaneous instalments, with reconciliation the following year.

3. VAT payable (if VAT-liable). You must remit VAT collected from clients, net of deductible VAT. A business owner who forgets this provision is blocked at each filing deadline. A standard-rate service activity collects 20% of the pre-tax price: this sum is not yours—it merely transits through your cash.

Each of these three items is calculated differently by regime. The table below details them by status.

1. Open a Dedicated Savings Account#

Create a separate account labelled "Provisions – taxes, contributions, VAT." It is not a legal obligation but a budgeting discipline. You transfer a share of your collected turnover into it each month.

2. Calculate Your Provision Rate by Status#

The rate ranges from 30% to 50% by sector (goods, BIC services, BNC liberal), regime (flat-rate or real), and legal form (sole proprietor, EURL, majority SARL manager). See the table below.

3. Transfer the Percentage of Actually Collected Turnover Monthly#

For each invoice collected or sale realized, transfer the provision to the dedicated account. Do not provision a theoretical amount in advance; base it on actual cash inflows. If you invoice €5,000 but collect only €3,000 in the month, provision on the €3,000 collected.

4. Review Your Provision Account Each Quarter#

Compare the savings balance with cumulative contributions and taxes paid since 1 January. If the balance is higher, you will have a surplus to keep or reallocate; if lower, raise your rate from the next month.

5. Provision for Payment Timing Gaps#

URSSAF collects contributions the following month; income tax instalments follow their own calendar; VAT is remitted per your regime. Plan provisions to cover these lags: you must have cash at the deadline, not only at year-end.

6. Keep a Safety Buffer (10% to 15% of Annual Turnover)#

Beyond the three mandatory charges, keep a reserve of 10% to 15% of annual turnover to absorb a surprise (reconciliation, contribution increase) or a seasonal dip.

7. Adjust Your Provision Mid-Year#

When instalment notices and reconciliations arrive, recalibrate your rate. If you under-provisioned, raise the percentage; if over-provisioned, reduce it or allocate the surplus to professional investment.

*VAT = rate applicable to your sector (0%, 5.5%, 10%, 20%). Zero while under the VAT exemption. ** Flat-rate operators under the VAT exemption (turnover below €37,500 services or €85,000 commerce): no VAT to remit. *** VAT-liable under the real regime; percentages are orders of magnitude.

Notes: if your marginal tax rate is high (30% or more), increase the tax share. For a sector with frequent payment lags (construction, industry), add 5 to 10 points. For a very regular activity, you may reduce by 5 points.

Take a flat-rate sole proprietor providing services, with projected annual turnover of €60,000.

Each month you transfer €1,660 to the dedicated account. By December you have accumulated €19,920, matching your annual obligation.

A real case we advised: a service provider followed this discipline for 18 months. At reconciliation, she had saved €22,000 against an actual obligation of €20,100. The surplus funded equipment.

Seasonal Activity#

If your income concentrates over six months, provision more in the quiet months to anticipate the busy-season charges. A seasonal operator earning 80% of turnover in July–September should provision from the start of the year.

Fast-Growing Activity#

If your turnover grows 50% mid-year, recalibrate immediately. The provision based on the prior year will not suffice: instalments rise and you risk a default if you keep the old rate.

Election for Corporate Income Tax (EURL under IS)#

If you have elected corporate income tax, tax is computed on profit at year-end (no staggered income-tax instalments on your pay). You then mainly provision social contributions and VAT, plus corporate tax at year-end.

Majority SARL Manager and Minimum Contributions#

A majority manager falls under the self-employed regime: minimum contributions are due even without remuneration. Include this fixed amount in your monthly provision, independent of turnover.

1. Higher flat-rate social rate for liberal professions. The BNC flat-rate rate rose from 24.6% in 2025 to 25.6% in 2026 (about +1 point). Do not keep your 2025 calculation; update your rate from January.

2. Reduced ACRE from 1 July 2026. For businesses created from 1 July 2026, the ACRE exemption drops from 50% to 25% of contributions in the first year. If you benefit from ACRE, anticipate the contribution increase that follows.

3. Do not confuse VAT exemption and flat-rate ceiling. You can cross the VAT threshold (becoming liable) without leaving the flat-rate regime. The two thresholds do not coincide.

4. Mixing personal and professional funds is risky. Managing your provision on a mixed account exposes your bookkeeping to challenges. A dedicated account, even free, protects and clarifies.

At Hayot Expertise, we advise many self-employed professionals. One observation recurs: those who provision sleep soundly. No stress when income-tax instalments arrive; no panic when URSSAF reconciles.

Conversely, those who keep everything in a single current account often face a cash crisis. They borrow short-term, pay interest, and routinely underestimate their real obligation. One director we advised thought he owed €12,000 in taxes; with TNS contributions and VAT, the real obligation exceeded €35,000. He had saved only €8,000. Catching up was painful. Since then, he provisions 40% of turnover.

Hayot Expertise Advice. From the start of the year, open a dedicated savings account for provisions. Transfer 30% to 50% of collected turnover by status. Even with a margin of error, you will be covered. Each quarter, compare the balance to your real obligations. At year-end, the surplus is yours: keep it or invest it. This discipline eliminates most cash crises and makes your true net margin legible.
