Frequently asked questions
Do I need to declare my UK or US pension if it's already taxed there?▼
Yes — you must always declare it in France. The tax treaty determines who actually taxes it, but the declaration is mandatory regardless. UK government pensions (civil service, NHS, military) are taxable only in the UK but must still be reported in France via box 8TK.
I moved to France mid-year. Do I declare my full year's income?▼
Only income earned after your arrival date in France should be declared. For UK filers, this means converting your April–March P60 figures to a French calendar-year (Jan–Dec) amount — Fiscly helps you prorate this.
Do I need to declare my Wise, Revolut, or PayPal account?▼
Revolut with a French IBAN (FR...) since 2024: no declaration needed. Revolut with a Lithuanian IBAN (LT...): yes. Wise: yes (best practice). PayPal: only if your balance exceeded €10,000 during the year.
I'm an auto-entrepreneur. I declare my revenue to URSSAF monthly — do I still need to file a tax return?▼
Yes. A separate annual income tax declaration is always required, even if you pay taxes monthly via versement libératoire. You declare your turnover (not profit) on form 2042-C PRO.
My UK ISA is tax-free in the UK. Is it taxable in France?▼
Yes. France does not recognise ISA tax-free status. All interest, dividends, and capital gains earned inside an ISA are fully taxable in France at the flat 30% rate (PFU).
I've never filed in France and I've been here 3 years. What should I do?▼
File retroactively for each missed year. Voluntary disclosure is treated leniently — penalties are typically 10% of tax owed plus interest. The sooner you act, the better.
