Assumptions
- Income tax: 34% abattement then the 2026 progressive barème for a single person (one part), no other household income
- URSSAF social contributions 25.6% of gross revenue (2026, non-regulated liberal, general regime)
- Year 1: ACRE modelled as 75% of the full URSSAF rate (19.2%) from 01.07.2026 (Bpifrance / LFSS 2026); eligibility is restricted and requires an URSSAF claim (needsReview vs live URSSAF tables)
- ACRE duration approximated as Year 1 only (statutory end is end of the 3rd civil quarter after start)
- CFP training contribution 0.1% of gross revenue (non-regulated liberal profession; regulated professions pay 0.2%)
- Micro-BNC receipts ceiling €83,600 for 2026-2028 (service-public Entreprendre F32105); the rate calculator marks targets that require gross above this ceiling as unreachable
- The versement libératoire (flat 2.2%) and régime réel options are not modelled
- Effective rate is total tax and contributions over gross revenue
