8 Legal Tax Optimisation Levers for Freelancers
Optimising your taxation is not illegal: it is using the devices provided by law to avoid paying more than necessary. Not to be confused with fraud, which consists of concealing. Here are eight legal levers, accessible to the self-employed, with their logic and limits. No miracles, but real, cumulative savings.
1. Choose the right tax regime
The first lever, often the most powerful, is the choice between micro and real. If your expenses exceed the micro flat allowance, the real regime reduces your taxable base. Conversely, if your expenses are low, the micro and its allowance win. This choice is reassessed each year: see real regime or micro-enterprise.
2. Arbitrate the flat-rate income tax
Under micro, the flat-rate income tax (1%, 1.7% or 2.2% of revenue) replaces scale-based tax. It is only advantageous if your marginal tax rate is at least 11%. Below that, it makes you pay tax you should not have. The right trade-off depends on your household's overall income.
3. Deduct all your actual expenses
Under the real regime, every justified business expense reduces the profit. Many freelancers under-deduct through ignorance: contributions, housing share, mileage scale, amortisation. The list of deductible expenses is your ally.
4. Fund a retirement savings plan (PER)
The Retirement Savings Plan (PER) is one of the few genuinely worthwhile tax-reduction tools for a self-employed person. Contributions are deductible from your taxable income, within a limit linked to the PASS. You reduce your tax today while preparing your retirement — a double advantage detailed in the self-employed PER.
5. Choose the right company form
Beyond a certain income, moving to an SASU or EURL under corporate tax opens the salary/dividend trade-off. You withdraw only what you need, leave the rest in the company taxed at corporate tax (15% up to €42,500), and steer your personal taxation. Our status comparator quantifies the tipping point.
6. Optimise the salary/dividend split
In a company under corporate tax, the balance between remuneration (charged but rights-generating) and dividends (less charged in an SASU) is a major lever. There is no universal rule: it all depends on your income and social-protection needs. We detail the scenarios in dividends or salary in an SASU.
7. Take advantage of first-year devices
ACRE reduces your contributions in the first year (50%, cut to 25% for registrations from 1 July 2026). Certain zones (urban tax-free zones, revitalisation areas) open temporary exemptions from tax or CFE under conditions. Check your eligibility before setting up.
8. Smooth your income over time
A revenue spike one year can push you into a higher bracket. Deferring the collection of an invoice, spreading an investment, or modulating withdrawals in a company can smooth the tax burden. Good cash management also serves this goal: see managing irregular cash flow.
What to remember — and avoid
Key takeaway: the most profitable optimisation for a freelancer is almost always the right choice of regime and status, before any exotic device.
Stay within the law: avoid artificial arrangements, false foreign domiciliations or fictitious expenses. The administration reclassifies these abuses, with penalties. The eight levers above are solid because they use the law as it is.
Start with the simplest: check that your regime and status suit your current income level with the status comparator and the micro-enterprise simulator. That is where the biggest savings hide.
