Moving a Foreign Home into a Trust: The Taxes and Forms on the Day It Moves
A September 2026 trade report says a new decree extends those two taxes to entry.
Imagine a couple in their seventies with a home in Spain, a flat in Mexico and a small house in England. They want all three to sit in one family trust, so their two children will not need a court in each country. They ask a simple question. If we sign the papers on Monday, what is charged that day? The home values below are round examples, not a forecast.
What each place does on the day
| Place | What happens when the home goes in |
|---|---|
| UK | A gift with no mortgage has no price, so no stamp duty land tax. A mortgage the trust takes over counts as a price. In a relevant property trust, inheritance tax is charged on entry at 20% above GBP 325,000 (about US$420,000), with up to 6% every ten years. |
| Spain | Spain does not recognise trusts. A tax-office ruling treats an irrevocable trust with a named beneficiary as a taxable gift when it is created. The state scale for gifts runs from 7.65% to 34%. |
| Mexico | Putting a home into a Mexican bank trust counts as a sale for tax when the owner names someone else as beneficiary and cannot take the home back. |
| Portugal | A home put into a company as capital is a paid transfer for the transfer tax. A gift is outside that tax and falls under stamp tax at 10%, plus 0.8% on a property gift. Spouse, children and parents are exempt. |
| Italy | A trust can hold Italian property. A trade-press report (tier U) says that from 1 January 2025 the gift and inheritance tax on trust assets is normally due on distribution, though the settlor may choose to pay at entry. The mortgage and cadastral taxes are unsettled, see below. |
| France | Funding a trust with a French link is taxed as a gift, at up to 60%. Trust assets not declared pay 1.5% a year. |
| US | A gift of a home, wherever it stands, into an irrevocable trust uses the gift tax. The lifetime exclusion is US$15,000,000 in 2026. A foreign trust brings Form 3520, with a penalty of the greater of US$10,000 or 35% for a missed filing. |
| Canada | Only certain trusts can claim the principal residence exemption. Most trusts are treated as selling their property at market value every 21 years. |
Which source says what
The UK stamp duty point comes from one law firm's page (tier C). It adds that trustees of a settlement file the return and that the 5% higher-rate surcharge applies to them on a purchase. The entry charge of 20% comes from the UK tax office's own manual (tier A), the same manual that says a UK home stays inside UK inheritance tax even when a foreign company holds it.
The Spanish ruling is a binding answer from the tax office dated 2016 (tier B). In that case the beneficiary was not a Spanish resident, so no Spanish gift tax arose. A 2026 note from a Spanish law firm repeats the point (tier C). The Spanish land register does not accept a trust as owner (tier B).
The Mexican rule is in the federal tax code (tier A). The code does not list the case where the owner stays the beneficiary and keeps the right to take the home back. A bank trust is also the only way a foreigner holds a home in the restricted zone, within 100 km of a border or 50 km of a coast, with a Foreign Ministry permit (tier A).
For Italy the sources differ. A trade-press report gives the 2025 rule above (tier U). An earlier law-firm source gives 2% mortgage tax and 1% cadastral tax when the home moves to the trustee. A September 2026 trade report says a new decree extends those two taxes to entry.
For France, sources differ on the fine for a missed trust form. Newer sources give a fixed EUR 20,000. Older sources give EUR 20,000 or 12.5% of the trust's value, whichever is higher. The 1.5% is a separate yearly levy on trust assets that are not declared.
The forms that follow
In the UK, a foreign company that holds UK land must join the Register of Overseas Entities and name its beneficial owners. Trustees can be registrable. Trust details go to the tax office and are not shown to the public. In France, a trust or other entity holding French property owes 3% of market value each year unless it files the yearly exemption form. In Canada, a resident who gives property to a non-resident trust files form T1141, with a penalty of CAD 2,500 up to 5% of value.
A fair objection
You might say: a trust is meant to save tax, so why would it add a charge on day one? In several places it does not. In the UK a gift with no mortgage has no stamp duty land tax. In Italy the tax is normally postponed. The charge arrives in places that look through the trust to a person: Spain at the gift, France on the gift, Mexico where the owner gives up the home. Also, a gift keeps the giver's cost for later sale tax in the US, while a home that stays in the estate gets a new cost at death.
Doors you could open
You could list each home and ask for a written answer for each country, covering the day of transfer, the yearly charge and the forms. You could ask what your children file in the year after your death.
Have you moved a home abroad into a trust, or decided to leave it out? Share what decided it. Someone with the same three homes may be glad to read it.
