Mexico Property Inheritance: What Foreign Owners Need to Know
The Part Nobody Asks About Until It Matters
Four things about owning a house on this coast that are worth knowing before the conversation with a lawyer, not instead of it.
Mexico has no federal inheritance tax and no estate tax. Foreign owners hear some version of that, conclude the subject is handled, and move on.
It is broadly right. It is also roughly half of what matters, and how it applies to any particular estate is a question for Mexican counsel rather than for an article.
That is the point of everything below. The other half is not a tax at all. It sits in the structure every foreign owner on this coast already holds, whether or not they have read it since the day they signed.
One. The Trust Is the Constitutional Route, Not a Workaround
Mexican law reserves direct title within one hundred kilometres of an international border and fifty of a coastline. Residential property in Los Cabos generally falls within that restricted coastal zone.
The mechanism that resolves it is the fideicomiso: with a permit from the Ministry of Foreign Affairs, a Mexican bank holds legal title while the buyer, as beneficiary, holds the practical rights of ownership: to occupy, renovate, rent, sell, or leave the property to whomever they choose.
It is worth stating plainly, because the arrangement is still described in some quarters as a loophole. It is written into the Foreign Investment Law. It has been in ordinary use for decades.
The bank is a trustee, not a landlord: it holds legal title for the benefit of the beneficiary, and its role, powers and obligations are the ones set out in the trust deed and in the law.
Two. Fifty Years, and a Window Most People Miss
Article 13 of that law sets the maximum term of these trusts at fifty years, extendable on request.
The detail worth carrying is procedural: the extension is applied for through the trustee bank, before the Ministry, in the final stretch of the term rather than after it.
Fideicomisos may generally be extended through the applicable legal and banking process. Knowing when the clock started is the part owners more often miss.
A trust bought second-hand carries the years already run by the previous owner, which is not always what the buyer assumes.
Three. One Line Decides Whether the House Goes to Court
A fideicomiso can name substitute beneficiaries, the fideicomisarios sustitutos. Where they are named, the transfer on death is an administrative matter settled with the trustee bank.
Where they are not, the transfer is generally resolved through Mexican succession procedures instead, which tend to take considerably longer, and longer again when the heirs live abroad.
How a particular estate is treated can depend on the deed and on individual circumstances.
The house does not pause while that runs. Dues, utilities, staff, property tax and the trustee's annual fee carry on, and they fall to people who may not yet hold the authority to sell.
Naming a substitute takes a single clause. Failing to name one can result in a significantly more complicated succession process.
Four. The Trust Settles Mexico, and Only Mexico
A fideicomiso resolves Mexican succession. It does not move a Mexican house outside an American estate.
United States citizens are taxed on worldwide assets wherever they live and wherever the asset sits, and the estate return counts this one with the rest.
Nor is there relief by treaty. The United States has estate tax treaties with roughly fifteen countries. Mexico is not among them.
And the trust does not coordinate itself with a will or a living trust drafted elsewhere. Where the two documents name different people, the outcome is not something an article can predict: it turns on the deed, on the governing law and on the facts.
It is also how a carefully built estate plan ends up quietly contradicted by a form signed at closing, and it is exactly the conflict that counsel in both countries exists to resolve.
The Part That Belongs to a Professional
Everything above is a matter of public record and can be checked in an afternoon. What follows cannot.
The absence of inheritance tax applies to the transfer, not to what happens afterwards. A later sale is a taxable event in Mexico, the two countries do not calculate the gain the same way, and the right answer depends on residency, on how the succession was documented, and on the rest of an estate that has nothing to do with this coast.
That is a conversation for Mexican counsel and a tax adviser who can see the whole picture, and it is worth having before it is urgent rather than after.
The Question That Opens It
Most owners here have a trust deed in a drawer and no clear memory of what it says. The ones who finally read theirs usually do it for an unhappy reason. A diagnosis, a death in another family, a question from a lawyer they could not answer.
There is one question worth answering first, and it takes a phone call to the trustee bank: does the deed name a substitute beneficiary, and is it still the right name?
Everything else can wait for the professionals. That cannot.
An introduction to Mexican counsel who handle these reviews can be arranged.
General information, current at the time of writing, and not legal or tax advice. Succession and tax treatment turn on individual circumstances and on rules that change. Confirm with Mexican counsel and a qualified tax adviser.
