Every figure above is a separate call to the same engine the calculator uses, run at build time on 2026-08-12. The green column is the best available outcome at that income.
The France options, priced
- Standard rates. Ordinary French income tax plus social contributions on investment income.
France has one regime to model here, which makes the structure and the residency date the only levers that matter.
What actually moves the number
- French social contributions on investment income are the part that moves the number, not the headline income tax rates.
- France taxes the household rather than the individual, so a spouse and children change the result materially.
- The engine models a single person with no dependants, which is the worst case for France specifically.
When France starts taxing you
Your home or principal place of stay being in France, or your main professional activity, or the centre of your economic interests. France reaches residence more easily than the day count suggests.
The other half is the UK side. Leaving the UK tax net is the Statutory Residence Test, and running a UK company from outside the UK raises Central Management and Control and Permanent Establishment questions that are separate from your own residence. Running a UK limited company while living abroad covers both.
What this calculation assumes
- Social security is the weak point in this calculation. The model charges the destination country's employee contributions and drops UK National Insurance the moment residence moves. In practice UK NI often continues for a period after you leave, and which country you contribute to is set by a social security agreement rather than by where you are tax resident. Treat the take-home figure as the optimistic end of the range, and the gap is largest where the destination charges no social security of its own.
- Employer National Insurance is shown as an employer cost, so it is outside your take-home. It does not disappear when you move, and it is often the reason an employer says no.
- Cross-border scenario detected. Check the applicable double-tax treaty between United Kingdom and France.
- Single-filer bands; couples double thresholds. CEHR surtax 3%/4% above 250k/500k.
