Editorial policy

Sources

Every rate, threshold or amount comes from an official source, read and dated: autoentrepreneur.urssaf.fr, urssaf.fr, service-public, impots.gouv.fr, Légifrance, the BOFiP tax doctrine, economie.gouv.fr and the public files of the DGFiP and Insee. A blog, a firm or a company formation site is never a source. Anything uncertain, such as a reform announced but not voted, is not published.

One parameter file

Values live in a single file with their source and the date they were read. No page hard-codes a rate: when a parameter changes, every page and every calculator change together.

Checks

Before each release, automatic tests compare the engine with the worked examples of service-public, the minimum and maximum amounts published by the Urssaf and, on a grid of cases, the calculation model the Urssaf publishes for mon-entreprise. Any gap stops the release.

Review schedule

Full review in January (rates, social security ceiling, income tax scale), in July (rates changed mid-year) and whenever a new REI file is published. Last review: 2026-10-15.

Corrections

Any error reported to contact@netindependant.fr is checked, fixed and added to the tests. Calculation rules are on how we calculate.

Independence

No affiliates, no commercial links to banks, company formation services or accountants, no email collection. If the site ever shows ads, they will not sit above a calculator or inside a result.
