You invoice €3,000 this month. Do you know how much you actually have left?
In between, there are URSSAF contributions, CFP (professional training contribution), and income tax. SimuAuto does the calculation for you, using the official 2026 tax rates, and shows you your true NET amount—the amount you can actually spend.

WHAT SIMUAUTO DOES
━━━━━━━━━━━━━━━━━━━━
• INSTANT CALCULATION
Enter your revenue, choose your business activity: the result is displayed immediately. Monthly or annual, your choice.
• THE 5 BUSINESS ACTIVITIES COVERED
Buying/reselling, accommodation and catering, BIC service provision, BNC service provision, CIPAV liberal profession. Each has its own rates — and the difference is greater than you might think.
• RECOMMENDED SAVINGS
The exact amount to set aside each month so you're never caught off guard by your social security contributions.
• VAT CEILINGS AND THRESHOLDS
Gauges alert you when you're approaching your revenue threshold or the VAT exemption threshold.
• ACRE AND FULL-SALE TAX
The ACRE reduces your social security contributions by half for 12 months: the app tracks the expiration date. It compares the full-sale tax to the progressive tax scale to tell you which is more advantageous.
• WHAT ABOUT A COMPANY?
A comparison of sole proprietorship / SASU / EURL, with the same revenue, to determine if your status is still the right one for you.
