Donating Real Estate in Mexico: Taxes and Process

Donating a house to a child, a spouse or a parent is one of the most common ways to pass on wealth during your lifetime in Mexico, and when planned well it can save taxes and avoid future conflicts. However, donating real estate is not as simple as signing a piece of paper: it requires a deed before a notary public (notario público), an appraisal and the payment of certain taxes and fees. In this guide we explain, in general terms, how donating a property works, which taxes apply and how it compares with inheriting or selling. Keep in mind that every case is different, so it is always wise to consult a notary and an accountant before making a decision.

What is the donation of real estate?

A donation is a contract through which one person (the donor) transfers ownership of an asset to another (the donee) free of charge, and the donee accepts it. When the asset is real estate, the donation must be formalized through a public deed before a notary public (notario público) and registered in the Registro Público de la Propiedad (Public Property Registry) so that it takes effect against third parties.

Unlike a sale, a donation involves no payment in return: it is a free transfer. And unlike an inheritance, a donation takes effect during the donor's lifetime, which lets you organize your estate in advance and see how the donated property is enjoyed.

ISR and the exemption between direct family members

The point that interests families the most is the Impuesto Sobre la Renta (ISR, income tax). As a general rule, whoever receives a donation obtains income that could be taxable. However, the Ley del ISR (Income Tax Law) provides an exemption for donations between direct family members when certain conditions are met.

Under current provisions, donations received in the following cases are usually considered exempt from ISR for the donee:

• Between spouses.
• From ascendants to descendants (for example, from parents to children).
• From descendants to ascendants (from children to parents), with certain conditions to prevent the property from being re-donated in a chain.

For donations between other relatives or between people with no direct family relationship, there is usually different treatment and only a portion may be exempt, with the excess being taxed. Amounts, limits and conditions change over time, so it is essential to confirm the tax treatment that applies to your case with an accountant or the notary before the deed is signed.

If the donee later sells the property received, they will need to look at the ISR on the sale of a house, since the value stated in the donation deed usually serves as a reference for the acquisition cost when calculating the gain.

ISAI and other costs that do apply

Even if ISR may be exempt between direct family members, donating real estate generally triggers the Impuesto Sobre Adquisición de Inmuebles (ISAI, real estate acquisition tax), also called the property transfer tax (traslado de dominio) in some states. This is a local tax paid for acquiring ownership of real estate, whether through purchase, inheritance or donation.

ISAI is calculated on the value of the property (normally the highest of the appraisal, the cadastral value and the transaction value), and its rate varies by municipality or state. That is why it is wise to ask the notary for an estimate of the total costs before starting the process.

Exact figures depend on the state, the municipality and the value of the property, so the table above is only a guide. Always ask the notary for a written breakdown and avoid signing without knowing the approximate total cost.

The notary process step by step

The donation of real estate must be formalized in a public deed. Although each notary's office may have variations, the general process usually follows these steps:

1. Go to a notary public (notario público) and explain your intention to donate or receive the property.
2. Gather the documentation: current deed to the property, IDs of the donor and donee, CURP, RFC, certificates proving the family relationship, and receipts showing the predial (property tax) and water bills are paid up to date.
3. Request the appraisal from an authorized appraiser.
4. The notary verifies that the property is free of liens by obtaining a certificate of freedom from encumbrances (certificado de libertad de gravamen).
5. The donation deed is drafted, in which the donor donates and the donee expressly accepts.
6. The corresponding taxes and fees (such as ISAI) are calculated and paid.
7. Both parties sign before the notary and the deed is registered in the Registro Público de la Propiedad.

Donate, inherit or sell: which is best?

Donation is just one of the ways to transfer real estate within a family. Each option has advantages and disadvantages worth weighing according to your situation:

Donation during your lifetime

It lets you organize your estate in advance and, between direct family members, take advantage of the possible ISR exemption for the donee. On the downside, the donor loses ownership immediately and the transaction triggers taxes and costs at the time the deed is signed.

Inheritance through a will

The property is transferred only upon the owner's death, and the owner keeps ownership while alive. It usually requires probate proceedings (juicio sucesorio) or an estate settlement before a notary, which can take time. Look at this route in depth in our guide on wills and inheritance of properties.

Sale

It involves real payment for the property and can generate ISR for the seller (with possible exemptions for a primary residence under certain requirements). It is useful when there is genuine consideration, but simulating a sale to "save" on taxes can lead to tax problems.

Risks and precautions

A donation is irrevocable in most cases, except in very specific situations provided for by law. Before signing, consider these points:

• Loss of control: by donating, you stop being the owner. If you need to keep using the property, consider arrangements such as usufruct (usufructo).
• Effect on other heirs: donating to only one child can create conflicts or even affect the legitimate share (legítima) of other heirs.
• Future tax impact: the value of the donation may influence the ISR when the donee sells the property.
• Hidden liens: verify that the property is free of debts, mortgages or unpaid predial before the deed is signed.

For all of the above, do not make the decision based solely on general information from the internet. Each state has local rules and each family has a different situation: rely on a trusted notary and accountant.

Frequently asked questions

Is a donation between parents and children subject to ISR?

As a general rule, donations from ascendants to descendants are usually exempt from ISR for the recipient, provided the legal conditions are met. Even so, other local taxes and fees, such as ISAI, generally do apply. Confirm your case with an accountant or notary.

Can you donate a house that still has a mortgage?

It is usually complicated, because the property carries a lien in favor of the creditor. In practice, it is common to need to release the mortgage or obtain the corresponding authorization. Discuss your specific case with your notary and the lending institution.

Can I donate only part of the property?

Yes, it is possible to donate a percentage of the property, leaving the donor and the donee as co-owners. Each situation has legal and tax implications, so it is best to review it with the notary.

Can a donation be reversed?

In general, a donation is irrevocable, except for specific grounds provided by law (for example, certain cases of ingratitude or non-compliance). Do not count on being able to undo it easily; decide with certainty and professional advice.
