French tax reduction schemes, and what they cost you
A tax reduction scheme is not an investment that happens to save tax. It is a sum spent in the hope that it will cost less than the tax it erases.
French tax reduction schemes fall into three families that share neither their purpose nor their risk. Overseas investment under articles 199 undecies B and 199 undecies C buys a one-off reduction of tax against capital paid out with no expectation of return, and that reduction can be recovered from the taxpayer if the operation fails its operating conditions. Subscription to innovation or regional funds under article 199 terdecies-0 A gives a reduction against capital that stays invested, illiquid for several years, and whose value may fall. The property deficit of article 156 is not a reduction at all: it deducts expenditure the owner has actually paid, with no capital lost and no possibility of recovery. The first useful reflex is to know which of the three you are being offered.
Overseas investment: what you buy, and what you risk
The mechanism fits in one sentence. You finance productive equipment or social housing in the French overseas territories, you expect no capital back, and in exchange you obtain a reduction of income tax greater than the sum paid. The return on the operation is that gap and nothing else: there is no market return, no capital gain, no repayment. The capital is lost by construction, and that is normal rather than a warning sign.
The risk is therefore not a market risk. It is the risk that the reduction is recovered. Relief is granted on condition that the asset is retained and operated for a minimum period by the local operator. Where that condition fails, through operator default, equipment never installed, or a structure that does not meet its requirements, the administration recovers the relief from the taxpayer who claimed it, not from the promoter who arranged it. The standing of the promoter, the existence of a completion guarantee and the solidity of the operator are consequently the only things that separate two operations that look identical on paper.
A reservation that matters more if you hold impatriate status
A reduction of tax is worth nothing beyond the tax actually due. A foreign national living in France under the impatriate regime has, by construction, a smaller taxable base than an ordinary resident on identical remuneration: the impatriation bonus is exempt, and so is half of qualifying passive income from foreign sources. Sizing a scheme against the tax you believed you owed, without first working out the tax you actually owe, means buying relief that will partly set off against nothing. The verification of the tax actually due comes before subscription; it does not follow it.
Innovation and regional funds
Subscribing to an innovation fund or a regional investment fund opens a reduction of income tax under article 199 terdecies-0 A. Unlike overseas investment, the capital is not written off in advance: it remains invested in unlisted companies, with everything that implies. The holding is illiquid for several years, a minimum holding period is imposed in order to keep the advantage, outcomes are very widely dispersed between funds, and management charges weigh on the net result. The reduction is acquired on subscription; the exit value is promised by nobody.
The property deficit, the soberest of the three
If you buy a French property to let and carry out maintenance, repair or improvement works, deductible charges can exceed the rent received. The excess is set against overall income within an annual limit, and the balance carries forward against property income of later years. This is not a structure: it is the deduction of expenditure the owner has borne directly. There is no capital lost, no condition held by a third party, and no recovery so long as the expenditure is evidenced and the property remains let for the required period. For a newcomer who buys and renovates, it is almost always the first scheme worth examining, and almost always the last one presented to them.
Frequently asked questions
Is an overseas investment scheme an investment?
No, and describing it as one is the main source of misunderstanding. The capital paid is lost by construction: there is no return, no capital gain and no repayment. The gain on the operation is the gap between the sum paid and the reduction of tax obtained, acquired once. What remains afterwards is not an asset but a risk: that the relief is recovered if the operation fails its conditions.
Who bears the risk if the overseas operation fails?
The taxpayer. Relief is granted on condition that the asset is retained and operated for a minimum period; where that condition is not met, the administration recovers the advantage from the person who claimed it, not from the promoter who arranged it. That is why the solidity of the operator and the existence of a completion guarantee are the only criteria that distinguish two operations in practice.
Can I subscribe to a reduction scheme while I benefit from the impatriate regime?
Nothing prevents it, but the arithmetic calls for caution. A reduction sets off only against tax actually due, and the exemption of the impatriation bonus together with the exemption of half of qualifying foreign passive income reduce that tax. Relief sized against an overestimated bill sets off partly against nothing, and the excess is generally lost.
What is the difference between a tax reduction and a tax deduction?
A deduction reduces the income on which tax is computed, so its value depends on your marginal rate. A reduction sets off directly against the tax due, so its amount does not depend on your rate, but it cannot exceed the tax you owe. Property deficits and retirement saving are deductions; overseas investment and innovation funds are reductions.
Is there a scheme with no risk of recovery?
The property deficit comes closest, because it rests on no undertaking held by a third party: it is your own expenditure, on your own property, deducted from your own income. The conditions to respect, being the nature of the works, the evidencing of the expenditure and keeping the property let for the required period, depend on you alone, which is true of neither of the other two.
