Real Estate Purchase and Sale: Complete Tax Guide for Buyers and Sellers

March 15, 2026 — Enrique Benet-Gregg

Tax Framework Applicable to Real Property Sales in Mexico

Every transfer of title to real property in Mexico simultaneously activates federal and state tax obligations on both parties to the transaction. The correct identification of who is subject to each tax, on what basis, and with what possibilities for deduction or exemption determines in many cases the economic viability of the transaction. This analysis disaggregates the four principal tax burdens: Income Tax (ISR) for the seller; Real Property Acquisition Tax (ISAI) for the buyer; Value Added Tax (IVA) when applicable; and structural deductions that mitigate the seller’s tax burden. Additionally included is an analysis of the international tax treaty regime, which constitutes the most relevant planning variable for foreign investors in the Riviera Maya corridor.

ISR on Sale: Seller’s Obligation

The sale of real property constitutes a taxable event under ISR pursuant to article 1, section I, of the Income Tax Law (LISR), in relation with articles 119 through 128 for individuals and article 18, section I, for legal entities. The taxable gain is determined by subtracting the proven cost of acquisition updated through the factors of the National Consumer Price Index (INPC) published by INEGI from the sale price, in accordance with article 124 LISR.

For individuals resident in Mexico, the applicable rate on the gain is 35% as the maximum marginal rate; however, article 121, in its proportional calculation mechanism, allows dividing the gain by the years elapsed since acquisition, applying the rate corresponding to that result and multiplying it again by the years elapsed, which frequently reduces the effective tax burden significantly. This year-averaging mechanism operates in accordance with the procedural provisions of article 121 LISR, distinct from sections I through V of the same article that enumerate authorized deductions, as is clarified in the following section. The notary who formalizes the transaction acts as a withholding agent and must calculate, withhold, and remit the provisional tax in accordance with article 126 LISR.

The most relevant exemption for individuals is that provided in article 93, section XIX, subsection a), LISR: the gain obtained from the sale of principal residence is exempt up to 700,000 investment units (UDIs), provided that the seller has not applied the exemption in the five preceding years and proves that the property is his principal residence. The SAT verifies this requirement through the taxpayer’s tax information.

For legal entities resident in Mexico or foreign entities with permanent establishment, the gain is included in the fiscal result of the fiscal year and is taxed at the corporate rate of 30% in accordance with article 9 LISR. Non-residents abroad without permanent establishment in Mexico are governed by a specific regime described below.

ISR Regime for Non-Residents Abroad without Permanent Establishment

Non-residents abroad who sell real property located in national territory without permanent establishment in Mexico are taxed in accordance with articles 161 and 162 LISR, specific provisions of Title V of the law that regulate the sale of real property by non-residents. Article 161 LISR establishes the rate of 25% on the gross income obtained, with no possibility of any deduction whatsoever, as the general withholding option that the notary must apply at the time of execution. Nevertheless, the same article 161 LISR grants the foreign seller the option to be taxed on the actual gain at the rate of 35%, for which it is an essential requirement that the taxpayer designate a legal representative in Mexico before the SAT in accordance with the rules of article 162 LISR and the applicable regulatory provisions. The choice between both options must be made prior to the notarial act, since once the tax is remitted under the 25% rate on gross income, the substitution becomes procedurally complex. To verify the current consolidated text of articles 161 and 162 LISR, including any reforms after 2021, it is recommended to consult the text published in the DOF and the systematized version available on the SAT portal.

Tax Treaties to Avoid Double Taxation: Determining Variable for the Foreign Investor

A variable frequently underestimated in the tax planning of sales by non-residents is the network of Conventions to Avoid Double Taxation and Prevent Tax Evasion (CDTIs) that Mexico maintains with the principal countries of origin of real estate investment in the Riviera Maya. These conventions may materially modify the applicable rate on the capital gain derived from the sale of real property in Mexico.

The four most relevant treaties for the real estate market in Quintana Roo are those executed by Mexico with the United States (in force since 1994), Canada (in force since 1992), Spain (in force since 1994), and Germany (in force since 2008). In general terms, the articles on capital gains in these conventions preserve Mexico’s right, as the source state, to tax gains derived from real property located in its territory; however, the conventional provisions on business income, permanent establishments, and foreign tax credit mechanisms in the country of residence may significantly reduce the effective consolidated tax burden on the investor. The concrete applicability of each treaty depends on the ownership structure used: a United States trust, a Canadian corporation, a Spanish company, or a German GmbH receive differentiated treatment both under Mexican domestic law and under the respective convention.

To access the conventional benefits, the foreign taxpayer must comply with the procedural requirements established in Articles 4 and 5 of the CFF in relation to the rules of the current Miscellaneous Fiscal Resolution: obtain or maintain registration in the Mexican RFC when required, demonstrate tax residency in the contracting state by means of a tax residency certificate issued by the competent authority of the country of origin with validity in the fiscal year of the transfer, and in some cases notify the SAT of the treaty application before or during the notarial act. Omission of these procedural steps may result in the notary applying the internal rate of 25% on gross income under Article 161 LISR without possibility of swift recovery of the differential, except through the refund procedure provided in Article 22 CFF, which is administratively burdensome. It is strongly recommended to verify the procedural status of the applicable treaty with sufficient advance notice before the closing of each transaction.

Authorized Deductions for the Seller

Article 121, subsections I through V, LISR enumerates the deductions that the individual seller may apply against income from the transfer. This enumeration is normatively distinct from the proportional calculation mechanism by years elapsed provided in the same Article 121 LISR, and both rules must be applied in a coordinated manner to correctly determine the provisional tax owed by the notary withholding agent in accordance with Article 126 LISR:

The proven cost of acquisition, adjusted according to the INPC from the date of acquisition to the month immediately preceding the transfer (Article 121, subsection I, LISR).
The amount of investments in construction, improvements, and expansions, likewise adjusted, provided that they are properly documented with digital fiscal receipts via internet (CFDI) (Article 121, subsection II, LISR).
The notarial fees, taxes, and rights paid by reason of the acquisition, as well as the ISAI actually paid on that occasion (Article 121, subsection III, LISR).
The commissions and mediation fees paid by reason of the transfer, substantiated with CFDI (Article 121, subsection IV, LISR).

The correct documentation of each of these items from the moment of the original acquisition is, in practice, the difference between a manageable tax burden and a confiscatory one. Investors who do not retain the complete documentary chain frequently see their deductions reduced or eliminated in an SAT audit.

ISAI: Tax Burden on the Acquiree in Quintana Roo

The Tax on Acquisition of Real Property is a local contribution whose regulation in Quintana Roo is found in Articles 27 through 42 of the Fiscal Law of the State of Quintana Roo and, for transactions in specific municipalities, in the corresponding municipal fiscal laws. The taxable event is the acquisition of real property or of real rights thereto located in the state, in accordance with Article 28 of said law.

The tax base is the greater of the agreed price, the cadastral value, and the value determined by an appraisal performed by an authorized appraiser. The base rate applicable in Quintana Roo is 2% on such base, in accordance with the Fiscal Law of the State; nevertheless, the municipal fiscal laws may establish supplementary rates, surcharges, or additional procedural modalities that affect the total effective rate applicable in each municipality. Consequently, the 2% rate should be understood exclusively as the state starting point, and it is essential to verify the municipal fiscal law in force in the location where the property is situated to determine the effective consolidated tax burden of the transaction. This tax is the obligation of the acquiree and is paid to the state fiscal authority in the same notarial act formalizing the purchase and sale. The notary is legally prohibited from executing the public deed without proof of payment of the ISAI.

The Municipalities of Benito Juárez (Cancún), Solidaridad (Playa del Carmen) and Tulum have competence to administer and collect the tax within their territories, with variations in both the applicable municipal rates and the appraisal and payment procedures that must be verified at the time of each transaction. Given the dynamic municipal legislative activity in the state, it is recommended to request official confirmation of the applicable amount from the corresponding municipal treasury before signing the private purchase and sale agreement.

VAT in Real Estate Transactions

The general rule regarding the transfer of real property intended for residential use is the exemption from VAT, provided for in article 9, section II, of the Law on Value Added Tax (LIVA). However, this exemption does not operate automatically in all transactions and its scope must be analyzed with precision.

The disposition of real property intended for commercial, industrial or hotel uses is not exempt and generates VAT at the rate of 16% in accordance with article 1 LIVA. In the context of the Riviera Maya, this has special relevance for the transfer of tourist units, boutique hotels, condominiums with vacation rental schemes under professional management and commercial premises. The analysis of the preponderant use of the property and the nature of the buyer is determinative in defining whether the transaction is exempt or taxable.

Determination of Preponderant Use and Vacation Rental Schemes

The category of greatest practical uncertainty for investors in the Riviera Maya corridor is that of properties operated under vacation rental programs managed by hotel operators, particularly those incorporating revenue sharing structures or guaranteed returns. In these schemes, the property is operationally integrated into a hotel or tourist inventory, the owner cedes control of the unit to a professional operator and receives a percentage of lodging income or a guaranteed fixed rent.

The SAT has historically maintained, through normative criteria and resolutions in binding consultation procedures (article 34 CFF), that real property incorporated into programs of this type must be classified in accordance with their effective preponderant use and not in accordance with their legal denomination as “residential property”. When the unit is regularly and systematically destined for the provision of lodging services through intermediation by a hotel operator, the SAT has concluded that the preponderant use is commercial or tourist, activating the 16% VAT rate for both the disposition and rental income. This position is based on the concept of preponderant use provided for in article 5, section I, LIVA, which links the right to credit and the causation of tax with the effective destination of the property.

As of the date of this analysis, there is no general normative criterion published by the SAT that conclusively resolves all scenarios of vacation rental programs with hotel operators. In the absence of a universal binding criterion, the prudent conduct for the investor or developer contemplating acquiring or transferring a unit under this scheme is to obtain an individual tax consultation before the SAT in accordance with article 34 CFF, describing with precision the contractual structure of the management program, before structuring the price and payment method of the transaction. The lack of prior definition exposes both the seller and the buyer to omitted VAT contingencies with updating, surcharges and possible penalties in accordance with articles 70 et seq. of the CFF.

VAT Withholding by the Acquirer: Obligations under Article 1-A LIVA

When the seller is a legal entity that files under the general ISR regime and transfers a property subject to VAT, the transfer of the tax to the acquirer must be expressly agreed upon in the purchase and sale agreement and reflected in the corresponding CFDI. The omission of this element has consequences both regarding deductions for the acquirer and withholding obligations when the buyer is also a VAT taxpayer.

When the acquirer is a legal entity or an individual with business activity registered under the general VAT regime, article 1-A LIVA imposes the obligation to withhold the value added tax transferred to it by the transferor in the cases provided for in said article. In taxable real estate transactions, withholding operates as follows: the acquirer-withholding agent must withhold two-thirds of the transferred VAT, remit that portion directly to the SAT through a separate withholding declaration from its own VAT declaration, and cover the remaining third to the seller together with the transaction price. This mechanism means that the seller does not receive 100% of the transferred VAT at the time of closing, which must be considered when structuring the financial flows of the transaction.

For the acquiring-withholding party, the withheld VAT must be declared in the period corresponding to the operation and cannot be offset or credited until the CFDI issued by the seller meets all applicable tax requirements, including the indication of the withheld amount. The withholding declaration must be filed in accordance with the rules of the current Miscellaneous Tax Resolution. Institutional buyers, real estate investment funds, and developers that make frequent acquisitions must incorporate this mechanism into their CFDI closing and review processes to avoid contingencies of improper crediting or omitted declarations.

Tax Regime for Real Estate Sales Through Trust

Real estate located in the restricted zone (50-kilometer strip from the coastline) is acquired by foreign nationals through bank trusts authorized pursuant to article 27 of the Constitution and articles 10 to 14 of the Foreign Investment Law. From a tax perspective, the establishment of the trust does not by itself constitute a disposition for income tax purposes, as established in article 14-A of the Federal Tax Code (CFF), provided that the control and transmission requirements set forth in said article are met. The subsequent transfer of trust beneficiary rights does constitute a disposition and activates all obligations described in this analysis, including the application of the regime under article 161 LISR for the foreign cedent and the evaluation of conventional treaty benefits applicable according to the tax residence of the settlor or assignee.

Relevant Jurisdictional Criteria

The judicial criteria described below have been identified for their substantive relevance to real estate transactions in Quintana Roo. In compliance with applicable citation standards, it is noted that the following references describe the criteria by their substantive content; for the identification of the thesis number, IUS registry, and publication data in the Federal Judicial Weekly, it is recommended to use the IUS search engine available at sjf.scjn.gob.mx, entering the key concepts of each criterion. Criteria not identified with a verifiable thesis number or registry are not cited with specific publication data in order to preserve information accuracy.

The Collegiate Courts of the XXVII Circuit (headquartered in Quintana Roo) have established relevant criteria regarding real estate valuation for ISAI purposes, particularly concerning the hierarchy between assessed value, agreed price, and appraisal value when significant discrepancies exist among them. The consolidated position of that circuit is that the tax authority cannot depart from the highest value without properly substantiating and reasoning its determination. For the identification of the specific amparo suit or suits on which this criterion is based, including case number and resolution date,

The Second Chamber of the SCJN has repeatedly held that local taxes on real estate acquisition do not violate the principle of tax proportionality provided for in article 31, section IV, of the Constitution, when the taxable base reflects the real market value of the asset. This criterion supports the validity of the appraisal system applied in Quintana Roo. The identification of the corresponding thesis number and IUS registry may be performed through a search in the Judicial Weekly using the terms “tax on real estate acquisition,” “proportionality,” and “Second Chamber.”

In the matter of income tax, the First Chamber of the SCJN has held that the adjustment of acquisition cost by INPC factors is part of the constitutional recognition of the proportionality principle, by preventing inflation from generating a taxable fictitious gain. This criterion reinforces the importance of correctly documenting the dates and values of acquisition and is invocable in review proceedings in which the SAT challenges the adjustment factor used. Precise identification of the thesis and its registry may be performed in the Judicial Weekly using the terms “adjustment,” “acquisition cost,” “INPC,” and “First Chamber.”

Practical Implications for Investors and Owners

Tax planning for a real estate sale in Quintana Roo must begin before the signing of the private purchase agreement and not at the notary’s office. The elements that must be defined in advance include: the determination of the tax regime of the seller and buyer; the existence or non-existence of income tax exemption for primary residence; the analysis of the use of the real estate for VAT purposes, with special attention to the classification of the preponderant use in properties with vacation rental programs; the availability and currency of deduction documentation of the seller; the verification of the current assessed value to project the ISAI base; the verification of the municipal rate applicable in the municipality where the real estate is located; and, for foreign buyers, the evaluation of the applicability of a treaty for the avoidance of double taxation and prior compliance with procedural requirements to access its benefits.

For larger-scale operations, particularly acquisitions by funds, developers, or structured investment vehicles, the tax burden of the transaction must be modeled as part of the return analysis, incorporating both immediate contributions and the implications of the chosen ownership structure on future disposals or profit distributions. VAT withholding under Article 1-A LIVA must be integrated into the closing cash flow model when the acquirer is a VAT taxpayer.

IBG Legal has structured the VAT analysis for vacation rental assets in the Tulum to Cancún corridor, including the determination of preponderant use in units incorporated into hotel management programs and the defense of ISAI valuations before the Collegiate Courts of the XXVII Circuit. Our practice serves national and international investors, developers, and funds in the structuring, negotiation, and closing of complex real estate transactions throughout the Riviera Maya and Mexican Caribbean, with the capacity to coordinate analysis of the applicable tax treaty according to the tax residency jurisdiction of the foreign investor.
