This is a calculation aid, not tax advice. It estimates your position based on the figures you enter and general rules that may not fit every situation. You are solely responsible for verifying these numbers and your final declarations — we accept no liability for errors or omissions. Consult a qualified tax advisor if your situation is complex.

Why the French and UK figures differ: France allows mortgage interest as a direct expense deduction; the UK replaced that with a 20% tax credit in 2020. Same property, same year — two different taxable profit figures. This is expected, not an error.

Two things we can't fill in for you
Your SA100 doesn't show your UTR or National Insurance number when downloaded blank — HMRC only prints these on your personal copy, or you can find them in your HMRC online account. Copy them onto page 1 by hand before sending.
Form 2042 also asks for your date and place of birth ("état civil"). We don't collect that for privacy reasons — fill it in by hand from your ID document, exactly as the form requests.
Calculation aid only — not tax advice. Verify all figures and current-year box numbers before filing. You are responsible for the accuracy of your declarations.
