The impatriate regime does not forgive improvisation: most of the benefits are decided before the contract is signed, and the rest in the first tax return. Eight recurring mistakes, their cost — and the fix.
The scenario: the package is negotiated globally (« €180,000 all in »), nobody thinks of identifying an impatriation bonus, and the addendum supposed to create it is signed three months after the start of duties.
The cost: the exemption for the actual amount requires a bonus stated — or determinable — in a contract or addendum drawn up before the start of duties (BOI-RSA-GEO-40-10-20, § 60). A late addendum repairs nothing.
The fix: since the 2019 Finance Act, the election for the 30% flat rate saves the situation for duties taken up on or after 16 November 2018 — including for intra-group mobility. But the flat-rate amount is carved out of the agreed remuneration: a bonus negotiated on top remains preferable. See the impatriation bonus page.
The scenario: the family returns in July for the school year, the person settles in, then signs in November with a French employer.
The cost: exclusion from the regime. Persons who came to work in France on their own initiative, or who were already domiciled in France at the time of recruitment, are out of scope (BOI-RSA-GEO-40-10-10, § 80). The lost benefit runs to tens of thousands of euros per year for eight years.
The fix: sign (contract, addendum or documented offer letter) before the move, keep proof of the foreign home at the time of recruitment (§ 90), and use the household settling-in tolerance to manage the family calendar. The guidance also accepts an application sent from abroad (§ 80, remark). See the returning from Dubai page.
The scenario: an employee transferred by their UAE subsidiary presents themselves as « recruited directly abroad » (or vice versa), without documenting the links between the entities.
The cost: for duties taken up before 16 November 2018, the qualification governed access to the 30% flat rate — the Conseil d'État upheld the refusal of the flat rate to an employee on intra-group mobility under the old law (CE, 22 December 2020, no. 427536). Today, the stakes are mainly evidentiary: each channel has its own supporting documents, and an inconsistent file weakens the entire regime in the event of an audit.
The fix: qualify the channel from the negotiation stage (capital links within the meaning of article L. 233-3 of the French Commercial Code for intra-group; application and foreign residence for external) and build the corresponding evidence file.
The scenario: « I left in 2021, I am returning in 2026, that makes five years. » Except the departure took place in September 2021 — the person was a French resident for part of 2021 — and the condition is assessed in full calendar years: for duties starting in 2026, non-residence is required from 2021 through 2025.
The cost: returning a few months too early loses everything, where postponing the start of duties to the following 1 January would have been enough. Additional traps: years spent as a VIE volunteer or as a public servant on assignment abroad, which keep the tax domicile in France (art. 4 B, 2 of the CGI; TA Paris, 23 May 2017, no. 1612516), and « grey » years where French residence was never properly broken.
The fix: reconstruct residence year by year for the five calendar years (tax assessments, TRC, leases), and choose the start-of-duties date accordingly. Our eligibility test builds in this count.
The scenario: the exempt bonus stays in the pre-filled amount of box 1AJ, or the exempt salaries are not entered in 1DY/1EY; the elections (flat rate, cap) are not stated anywhere.
The cost: tax paid on exempt amounts, a distorted reference tax income, elections deemed not exercised. A claim remains possible within the time limit of article R* 196-1 of the LPF for the over-taxation, but the retroactive exercise of the elections is uncertain.
The fix: follow the step-by-step on the tax returns page — check the pre-filled amounts, 1AJ/1BJ for the taxable, 1DY/1EY for the exempt, an express statement for the elections, 2047 and 2074-IMP for foreign income.
The scenario: the employer agrees to « a bonus », but the contract stipulates a global salary in which nothing distinguishes the supplement linked to the impatriation; or the bonus absorbs part of the market salary, pushing taxable remuneration below the reference remuneration.
The cost: partial or total requalification — the exemption is added back to the extent of the shortfall against the reference (CGI, art. 155 B, I-1, last para.), and an undifferentiated bonus is not a bonus.
The fix: a dedicated, quantified clause, separate from the base salary; a prior simulation of the bonus/reference pair; an employer certificate on the comparison method. The HR note contains a bilingual model clause.
The scenario: the impatriate claims the 50% exemption on the dividends from their Dubai securities account... which they never reported on form 3916.
The cost: a €1,500 fine per account and per undeclared year (CGI, art. 1736, IV), extended reassessment periods, and a devastating inconsistency in the event of an audit — the benefit of 155 B presupposes precisely foreign assets, visible to the tax authority through the automatic exchange of information.
The fix: an exhaustive inventory of foreign accounts, securities accounts, capitalization contracts and life insurance policies from the first return (3916/3916 bis; CGI, art. 1649 A and 1649 AA).
The scenario: in the fourth year, the impatriate accepts an offer from a competitor — outside the group — or goes abroad again on an eighteen-month assignment.
The cost: moving to a company outside the group ends the regime, with no possibility of reopening it (the five-year non-residence condition is no longer met). A year without French domicile is lost, and the eight-year end date keeps running (BOI-RSA-GEO-40-10-10, § 230 to 280).
The fix: factor the tax value of the regime into any mobility negotiation (a gross salary differential can be wiped out by the loss of 155 B); prefer, all else being equal, intra-group moves; anticipate the eighth-year « landing ». See the duration of the regime page.
