Divorce and Tax Residence Abroad: The Tax Consequences for Spouses
A divorce does not only dissolve a marriage: it also reshuffles the tax position of both spouses. When spouses no longer live in the same country, or when one of them moves abroad because of the separation, the tax residence of each becomes the central question. Income tax, maintenance, compensatory allowance, division of assets, real estate capital gains and French real estate wealth tax (IFI) are all affected, and the consequences are often underestimated.
As a tax lawyer, I offer here a practical guide to divorce and separate tax residence, for French nationals living abroad and for international couples.
1. Where is each spouse tax resident after separation?
The criteria for French tax domicile
Under Article 4 B of the French General Tax Code (CGI), a person is tax resident in France if their home or main place of stay is in France, if they carry on their main professional activity there, or if their centre of economic interests is located there. These criteria are alternative: meeting any one of them is enough.
After a separation, each spouse is assessed individually. The spouse who remains in the family home in France with the children generally stays French tax resident. The spouse who leaves does not automatically cease to be resident: the home, the main activity and the centre of economic interests must genuinely have left France.
Dual residence and tax treaties
Each State applies its own criteria, so a spouse may be regarded as tax resident in both France and the host country (Switzerland, Belgium, Italy, the United Kingdom, etc.). Bilateral tax treaties then provide tie-breaker rules, which look successively at the permanent home, the centre of vital interests, habitual abode and nationality.
At the time of divorce, however, these criteria become fragile: where is the “permanent home” of a spouse who keeps the family house in France but works abroad? A documented prior analysis is essential. For more detail, read our article on moving abroad and the taxation of financial assets.
2. Separate taxation of separated spouses and the year of divorce
In France, married spouses are in principle taxed jointly. Article 6-4 CGI nevertheless provides for separate taxation where spouses have separated their property and no longer live under the same roof, or where one has left the marital home and has separate income. This is common with separate residences, whether in two cities or in two countries.
For the year of the divorce itself, Article 6-6 CGI provides that each former spouse is taxed separately on the income they personally received and on their share of joint income. Each files their own return. Children are attached to one parent's household, or split in case of shared residence, which directly affects the family quotient.
What about the spouse who becomes a non-resident?
A spouse who leaves France and ceases to be tax domiciled there is taxed in France only on French-source income (rents, real estate capital gains, income from activities carried out in France, etc.). A minimum tax rate applies unless the person can show that the average rate would be lower. The position must be declared rigorously, as the tax authorities frequently challenge departures that coincide with a separation.
3. Maintenance and compensatory allowance: how are they taxed?
Maintenance paid to a former spouse or an adult child is deductible from the payer's total income under Article 156, II, 2° CGI, and taxable in the hands of the recipient. The tax residence of both payer and recipient affects whether the deduction is effective and whether the recipient's State of residence taxes it.
A compensatory allowance paid as a lump sum within twelve months of the divorce gives rise, subject to conditions, to a 25% tax reduction on payments of up to €30,500 (Article 199 octodecies CGI). This benefit notably requires the payer to be tax domiciled in France. Paid as an annuity, the allowance follows the regime for maintenance.
Please note: where the payer or the recipient lives outside France, the characterisation of the payment (capital, annuity, maintenance) and its treatment may differ from one State to another. The payment method should therefore be chosen before the divorce agreement is signed.
4. Dividing assets: duties, capital gains and IFI
The partition duty
Liquidating the matrimonial property regime triggers the partition duty (droit de partage) of Article 746 CGI, at 1.10% of the net assets divided. It is added to the notary's fees and, where applicable, to the land registry contribution. For significant real estate holdings, these costs must be budgeted.
French real estate owned by a non-resident spouse
A spouse who has become non-resident remains taxable in France on capital gains from the sale of French real estate. Article 244 bis A CGI imposes a specific levy on these gains, in addition to social charges. Article 150 U, II, 2° CGI provides, subject to time and ceiling conditions, an exemption for the sale of a former main residence by non-residents.
Non-residents are also liable to French real estate wealth tax (IFI) on their French property when its net taxable value exceeds €1.3 million. A division that allocates the house to one spouse therefore changes each spouse's IFI base.
Bank accounts and assets abroad
Accounts opened, used or closed abroad must be declared by French tax residents. A transfer of funds between former spouses, a portfolio division or the closing of a joint account are all occasions for reporting failures, which are sanctioned by heavy fines. They must be anticipated before liquidation.
5. Reminder: competent court and applicable law
On the civil side, within the European Union the competent court is determined by Regulation (EU) 2019/1111, known as “Brussels IIb” (habitual residence or common nationality of the spouses), and the applicable law by Regulation (EU) No 1259/2010, known as “Rome III”. Spouses may choose the law applicable to their divorce by a written, dated and signed agreement.
A valid foreign divorce judgment is recognised in France without exequatur (the 1860 Bulkley case; Article 30 of Brussels IIb within the EU). Its tax effect is immediate: it ends joint taxation. The choice of forum and law is therefore never tax-neutral.
6. Our advice before divorcing or separating abroad
Review your tax residence and your spouse's before any move, documenting the home, activity and centre of economic interests.
Check the tax treaty between France and each spouse's country of residence.
Choose the form of the compensatory allowance (capital or annuity) according to its tax treatment in each State.
Model the tax cost of the division: partition duty, capital gains, IFI and declaration of foreign accounts.
Coordinate the lawyer, the notary and the tax adviser in each country before signing the divorce agreement.
To secure your position, rely on an international tax and wealth lawyer.
FAQ: divorce and tax residence abroad
Where am I tax resident if my spouse and I live in different countries?
Each spouse is assessed individually. You are tax resident in France if your home or main place of stay, your main professional activity or your centre of economic interests is there (Article 4 B CGI). If another State also claims you, the tax treaty decides.
Can separated spouses be taxed separately before the divorce?
Yes, under Article 6-4 CGI, notably where the spouses have separated property and no longer live under the same roof.
How is the year of the divorce taxed?
Each former spouse is taxed separately on personal income and on their share of joint income (Article 6-6 CGI). Each files a return.
Is the compensatory allowance tax deductible?
Paid as a lump sum within twelve months of the divorce, it gives rise, subject to conditions, to a 25% tax reduction up to €30,500. Paid as an annuity, it follows the maintenance regime.
Does a non-resident pay IFI and capital gains tax when the family home is sold?
Yes for property located in France: IFI applies above €1.3 million of net taxable real estate, and gains are taxable in France (Article 244 bis A CGI), subject to exemptions.
Do I need a tax lawyer for an international divorce?
It is strongly advisable: the choice of forum, law, payment method and division has lasting tax effects in several States.
