Mexico Inheritance & Gift Tax Guide 2026

Overview — No Federal Inheritance Tax

Mexico does not impose a federal inheritance tax (impuesto a la herencia) or estate tax. This means that assets passed to heirs upon death are not subject to federal tax at the time of inheritance. However, the heirs step into the tax position of the deceased with respect to the assets received. The absence of an inheritance tax makes Mexico a favourable jurisdiction for wealth transfer, especially for high-net-worth individuals. Some states do impose their own inheritance or gift taxes, though at very low rates.

State-Level Inheritance and Gift Taxes

While there is no federal inheritance tax, several Mexican states impose their own inheritance and gift taxes (impuesto sobre herencias y legados). These vary by state and are generally quite low:

• Aguascalientes: 1% on inheritances exceeding MXN 1 million
• Jalisco: Up to 1.5% on inheritances (with exemptions for direct heirs)
• Michoacán: 1–3% depending on relationship and amount
• Sonora: 1.6% on inheritances (exemptions for direct heirs)
• Veracruz: 2% on inheritances (exemptions for spouses and children)
• Zacatecas: 1% on inheritances

Most states exempt inheritances between spouses and direct lineal descendants (children) and ascendants (parents). Even where applicable, the rates are very low compared to inheritance taxes in the US or Europe. Many states have no inheritance tax at all. A local notary or attorney should be consulted regarding the specific state where the deceased was domiciled.

Gift Tax — Gifts Between Spouses and Lineal Relatives Exempt

Mexico does not have a separate gift tax (impuesto sobre donaciones) at the federal level. Instead, gifts may be treated as income for the recipient under the ISR law, with important exemptions:

• Exempt gifts: Gifts between spouses, and between lineal ascendants (parents, grandparents) and descendants (children, grandchildren) are fully exempt from ISR
• Non-exempt gifts: Gifts to other recipients (siblings, friends, non-relatives) are treated as income to the recipient and subject to ISR at progressive rates (1.92–35%)
• Reporting: Exempt gifts must still be reported to the SAT through the annual return
• Cash gifts: Large cash gifts may raise money-laundering concerns; banks and notaries are required to report cash transactions exceeding MXN 15,000–100,000 depending on the activity
• Property gifts: Transfer of real estate by gift triggers ISAI (acquisition tax) at 2–5% in most states, payable by the recipient

Inheritance of a Business — ISR Implications

While the inheritance itself is not taxed, inheriting a business interest can have ISR implications:

• The heir receives the business assets with the same tax cost basis as the deceased had (step-up in basis does not apply in Mexico for most assets)
• When the heir eventually sells the business or its assets, capital gains tax will be due on the full appreciation from the original acquisition cost (plus inflation adjustment)
• If the business is a corporation, shares inherited are subject to the same cost basis rules
• The deceased's final tax return must be filed by the estate executor, covering income up to the date of death
• Asesoría fiscal (tax advice) is strongly recommended for complex estates involving business interests, real estate, or foreign assets

This lack of step-up in basis can create a significant deferred tax liability for heirs who later sell inherited assets. Planning strategies include gradually transferring assets during lifetime (through the gift exemption) or structuring ownership through holding companies.

Foreign Inheritance Considerations

For Mexican residents inheriting assets from abroad, or foreigners inheriting Mexican assets, the following applies:

• Mexican tax residents who inherit assets from abroad are not subject to Mexican inheritance tax (as there is none)
• However, once the inherited assets generate income (interest, dividends, rental income), that income is subject to Mexican ISR
• Foreign inheritance taxes paid abroad may be creditable against Mexican ISR on income generated by inherited assets (in some circumstances)
• Non-residents who inherit Mexican assets are subject to Mexican capital gains tax upon eventual sale
• Real estate in Mexico inherited by non-residents: no inheritance tax, but ISAI (2–5%) may be due on the registration of the transfer

Succession Planning

Common strategies for estate planning in Mexico include:

• Testament: A Mexican will (testamento) ensures smooth transfer according to the deceased's wishes. Without a will, Mexican intestacy law applies, which may not align with the deceased's intentions.
• Life insurance: Proceeds are not subject to ISR in Mexico. Policies can be structured to provide liquidity for estate expenses.
• Trusts (fideicomisos): Used primarily by foreigners holding Mexican real estate in restricted zones; also used for estate planning.
• Gifting during lifetime: Taking advantage of the spouse/lineal relative gift exemption to transfer assets gradually.

FAQs

Is there an estate tax like in the US?

No. Mexico has no federal estate tax. The US estate tax can apply to US citizens or residents who own Mexican assets, but Mexico itself does not impose an estate tax.

How is inherited property taxed when sold?

The heir inherits the deceased's cost basis. When the property is sold, capital gains ISR is due on the difference between the sale price and the deceased's adjusted cost basis. The primary residence exemption may apply.

Do I have to report a gift from my parents?

While gifts from lineal ascendants are exempt from ISR, they must be reported in the annual tax return as exempt income. This helps the SAT track the flow of funds and prevents money laundering issues.

Can I disclaim an inheritance?

Yes, a beneficiary can decline an inheritance. The disclaimed share passes to the next eligible heir according to the will or intestacy law. There are no tax consequences for disclaiming.
