Taxes on Selling Property in Quintana Roo 2026: Complete Guide

Selling a property in Quintana Roo, a market as dynamic as Cancún or Playa del Carmen, involves a series of tax considerations that, if not handled correctly, can significantly impact the profitability of your operation. Have you wondered what the exact taxes and associated costs will be when selling your property in 2026, and how you can optimize this process?

At Cancún Prime, we understand that for both experienced investors and homeowners, tax clarity is fundamental. This detailed guide breaks down the taxes on selling a property in Quintana Roo in 2026, offering you precise information to make informed decisions and ensure the best possible net gain.

The Tax Framework in Quintana Roo for 2026: What to Expect When Selling?

Quintana Roo’s real estate market, with its sustained growth in destinations like Tulum or Puerto Cancún, remains one of Mexico’s most attractive. However, the sale of a property is subject to both federal and state tax regulations. For 2026, the legal framework is projected to maintain the same pillars, though it’s always crucial to be aware of possible updates.

Main Taxes Involved

When selling a property in Quintana Roo, the main levies you should consider are:

• Income Tax (ISR): This is a federal tax on the gain obtained by the seller. It is, without a doubt, the most significant in terms of financial impact for the seller.
• Property Acquisition Tax (ISAI): Although this tax is paid by the buyer, it is part of the total transaction cost, and as a seller, understanding its impact on your property’s final price is valuable.
• Other Notary and Closing Costs: These are not taxes per se, but they are mandatory costs that affect your liquidity and must be taken into account.

Income Tax (ISR) for Property Sales in 2026

ISR is the most complex and heaviest burden for the seller. It applies to the “gain” or “profit” you obtain from selling your property. It is essential to understand how it is calculated and what factors can help you reduce it.

Who Pays It and What Is It Calculated On?

ISR is paid by the property seller. The basis for the calculation is the net gain, which is obtained as follows:

Sale Price - (Proven Acquisition Cost Adjusted for Inflation + Deductible Expenses) = Taxable Gain

In other words, the total sale amount is not taxed, but only the difference between the sale price and the original purchase cost (adjusted for inflation), plus a series of expenses permitted by law. The public notary, in their role as a withholding agent, will calculate and withhold this tax at the time of signing the deed, or, if applicable, will file the declaration if a definitive calculation is chosen.

The Importance of the Proven Acquisition Cost

The acquisition cost is the original value at which you bought the property. It is vital to have the original invoice or deed to prove it, as this amount is updated for inflation from the acquisition date to the sale date, which reduces the taxable basis for ISR.

“A common mistake is not keeping the original documentation that proves the acquisition cost of the property. This document is the cornerstone for a fair ISR calculation, and its absence can lead to a higher amount being taxed, even 20% of the total operation value if there is no way to prove the cost, especially for foreign residents without tax representation.” – Real Estate Tax Expert.

Deductible Expenses to Reduce ISR

The law allows you to deduct certain expenses and investments you made in the property, which reduces your taxable gain and, therefore, the ISR payable. It is crucial to have invoices or tax receipts for these concepts.

The main deductible expenses are:

• Investments in Construction, Improvements, and Extensions: All structural improvements or those that increase the useful life of the property (not simple maintenance). Examples include a major renovation, adding a floor, installing solar panels, etc. Invoices and, if applicable, construction permits are required.
• Notary Fees for Acquisition: Notary fees and other expenses (rights and taxes) you paid when you bought the property.
• Intermediation Commissions: Fees paid to the real estate agency for the sale, as long as they are properly invoiced.
• Appraisals: The cost of the real estate appraisal carried out for the sale operation, also with an invoice.

ISR Calculation: A Practical Example (2026 Projection)

To illustrate the impact, let’s consider a hypothetical scenario of selling a non-exempt property in Cancún in 2026. Marginal ISR rates can range from 1.92% to 35%, depending on the taxpayer’s annual income level. The notary usually makes an initial calculation and withholds an amount, which can be 20% or 25% of the sale price (if there is no provable cost or if it’s a foreigner without a representative), or a smaller amount if all deductions are available. The seller can opt for an annual “definitive calculation” with the SAT, where personalized ISR tables are applied.

Example: Sale of an apartment in Cancún’s Hotel Zone (not a primary residence)

This example shows how updating the acquisition cost and deducting expenses can significantly reduce the basis on which ISR is calculated. If in this same case, invoices for investments or commission were not available, the taxable gain would be much higher, increasing the tax.

ISR Exemptions When Selling Your Primary Residence in 2026

One of the most frequent questions from our clients is whether they can exempt ISR. Fortunately, Mexican law provides for a significant exemption for the sale of a primary residence, under certain conditions.

Requirements for Exemption

To be able to exempt ISR when selling your primary residence in 2026, you must meet the following requirements:

1. Must Be a Primary Residence: The property must be your main residence. This is proven with utility bills (electricity, telephone), bank statements, or voter ID (INE) in your name, with the property’s address, with at least 6 months of antiquity.
2. Tax Residence: You must be a tax resident in Mexico.
3. Frequency: You can only apply this exemption once every three years. If you have already used the exemption in the last three years (counted from the date of the previous sale), you will not be able to apply it again.
4. Maximum Amount: The exemption has a cap of approximately 700,000 UDIS (Investment Units). The exact value in Mexican pesos varies daily, but for 2026, this represents a considerable amount, often exceeding 5.5 million Mexican pesos (the current UDI value is around $8.0 pesos per UDI). If the sale value exceeds this amount, ISR will only be calculated on the excess.

Required Documentation

To prove that the property is your primary residence and access the exemption, the notary will request at least three of the following documents (in the seller’s name and with the property’s address, with a minimum antiquity of 6 months):

• Utility bills (electricity, water, landline phone, internet).
• Bank statements or department store statements.
• Voter ID (INE) with the registered address.

“The ISR exemption for selling a primary residence is a very valuable tax benefit that can save you hundreds of thousands of pesos. However, its application is strict and depends on proper documentary proof. Ensuring that utility receipts are updated and in the owner’s name is as important as having the deed.” – Notary Public in Quintana Roo.

Property Acquisition Tax (ISAI) and Other Costs

Although ISAI is paid by the buyer, it is essential for you as a seller to be aware of it, as it is part of the total cost of the real estate transaction and can influence the negotiation of your property’s final price. Additionally, there are other closing costs that are indeed the seller’s responsibility.

ISAI in Quintana Roo: Rates and Calculation Basis

In Quintana Roo, the ISAI rate is 2% of the property’s value. This tax is calculated on the highest value among:

• The agreed-upon purchase and sale price.
• The cadastral value (property value according to the municipal registry).
• The appraisal value issued by an authorized appraiser.

For example, if a property sells for $5,000,000 MXN, the ISAI for the buyer would be $100,000 MXN (2% of $5,000,000). This is a cost that the buyer considers when making an offer, so a competitive sale price, considering all these factors, is key to the fluidity of the operation.

Other Closing Costs for the Seller

In addition to ISR, the seller incurs other expenses that must be budgeted:

• Notary Fees (seller’s portion): Although the buyer covers most of the notary fees, the seller must pay a small portion covering the review of their documentation, preparation of certificates, and assistance with ISR withholding. This amount is variable but typically less than 1% of the operation value.
• Certificates and Proofs: Several documents are required to certify that the property is free of debts and encumbrances. These include:
• Certificate of No Property Tax Debt.
• Certificate of No Water Bill Debt.
• Certificate of No Encumbrances (Public Registry of Property).
• Certificate of No Maintenance Fee Debt (if applicable, in condominiums).
• Real Estate Commissions: If you used the services of a broker or real estate agency (like Cancún Prime), you will have to pay the agreed-upon commission, which generally ranges between 4% and 8% of the sale price, and must be invoiced to be deductible from ISR.
• Mortgage Cancellation Costs (if applicable): If the property has an active mortgage, the seller must cover the costs of its cancellation before the Public Registry, including notary fees and registration rights.

“The total cost of selling a property goes beyond ISR. Considering notary fees, certificates, and especially the real estate commission (which averages 6% in the region) is essential to calculate your true net gain and set a realistic sale price in the Cancún and Riviera Maya market.” – Real Estate Financial Advisor.

Smart Tax Strategies for Sellers in 2026

Knowing the taxes is the first step, but knowing how to manage them efficiently is what truly makes a difference in your pocket.

Deductible Investments: Prove Your Improvements

A common mistake is not keeping invoices for significant renovations or improvements. From installing air conditioning, an alarm system, expanding a room, to building a pool; all these investments, if properly invoiced and compliant with tax requirements, can be deductible and reduce your ISR. Make sure invoices are in the owner’s name and clearly specify the concept.

Specialized Advice: Key to Optimization

The tax system can be complex, especially if you are an investor with multiple properties, or if you have doubts about applying exemptions. Having the support of a tax advisor specializing in real estate or an experienced notary in these types of operations is invaluable. They can analyze your particular case, identify all applicable deductions, and guide you every step of the way, avoiding costly mistakes. At Cancún Prime, we always recommend advice from our experts to maximize profitability.

The Importance of Invoicing

For any expense to be deductible, it must be properly invoiced. This applies to real estate commissions, appraisals, construction or renovation fees, etc. Always request your Digital Tax Receipts via Internet (CFDI) and ensure they comply with SAT requirements.

Impact for Investors and Commercial Properties

If your sale is not a primary residence, tax considerations change. This applies to properties that are not your main residence, properties intended for vacation rentals, commercial premises, or land.

Considerations for commercial premises or multiple properties

For investors selling a commercial property, an apartment in Aldea Zama in Tulum used for Airbnb, or any property that is not their primary residence, the ISR exemption does not apply. In these cases, the ISR calculation is made on the net gain without the benefit of the 700,000 UDIS.

This is where proper documentation of the acquisition cost and all investments in the property becomes even more critical. The use of the property for commercial activities (such as active and declared vacation rentals) can, in some cases, allow for greater deductibility of expenses associated with its operation and maintenance, but this must be reviewed with a tax specialist.

Sale of pre-construction properties

Selling a property you bought pre-construction and never inhabited as a primary residence (either because you bought it for investment or because you finished it and decide to sell it immediately) will also be subject to ISR without the primary residence exemption. In these cases, the acquisition cost will include the developer’s purchase price and all payments made up to the final deed.

Frequently Asked Questions

Is ISR different for foreigners selling property in Quintana Roo?

Yes, there are some differences. Foreign residents abroad selling a property in Mexico can opt for a 25% withholding on the total amount of the operation (without deductions) or 20% on the net gain (with deductions). For the latter option, they must appoint a legal representative in Mexico and have all documentation to support the acquisition cost and deductions. The choice depends on the projected gain and the existence of proofs.

What if my property is a vacation rental?

If your property has been used as a vacation rental and not as your primary residence, you will not be able to apply the 700,000 UDIS ISR exemption. ISR will be calculated on the net gain, deducting all permitted expenses such as investments, commissions, and the adjusted acquisition cost. It is important to keep a detailed record of income and expenses.

Do I need a notary to sell my property?

Absolutely. In Mexico, the purchase and sale of real estate must be formalized before a Public Notary. The notary is the one who certifies the act, ensures the legality of the operation, calculates and withholds the corresponding taxes, and registers the new property in the buyer’s name. Without notary intervention, the transaction is not legally valid or registrable in the Public Registry of Property.

How long does the sales process with a notary take?

The notarial process for selling a property in Quintana Roo usually takes between 30 and 60 business days, once all documentation from both buyer and seller is complete. This time can vary depending on the agility of document delivery, the complexity of the operation (e.g., mortgage cancellation), and the workload of the notary office and government agencies.

Can I deduct the mortgage interest I paid?

No, interest paid on a mortgage loan is not deductible for the calculation of ISR on the sale of the property. Mortgage interest can be deductible from your annual ISR declaration as a physical person (when it concerns your primary residence and under certain limits), but not as a cost to reduce the gain from the alienation of the property.
