Yes, people in Mexico pay taxes, and the system will feel familiar if you’ve lived in any industrialized country. Taxes in Mexico include a progressive federal income tax that runs from 1.92% to 35%, a 16% value added tax built into most purchases, annual municipal property taxes, and social security contributions split between employer and worker. What you actually owe depends on whether Mexico considers you a tax resident and where your income comes from.
Who Mexico Treats as a Tax Resident
Mexico’s Federal Fiscal Code defines residency mainly through a “home” test rather than a day count. Under Article 9 of the CFF, if you establish a home in Mexico, you’re treated as a tax resident regardless of how many days you spend in the country. Renting and furnishing an apartment can be enough to trigger residency even if you travel frequently.
If you keep a home in Mexico and another country at the same time, the CFF looks at your “center of vital interests” to break the tie. Mexico claims you as a resident if either more than half of your annual income comes from Mexican sources or your main professional activities are based there. If neither applies, you’re generally treated as a non-resident.
The distinction matters. Residents owe Mexican income tax on their worldwide income no matter where it was earned. Non-residents pay Mexican tax only on income sourced within Mexico. A classification mistake can mean double-paying or accidentally failing to file.
Income Tax Rates for Residents
Mexico’s federal income tax, the Impuesto sobre la Renta (ISR), uses progressive brackets. For the 2026 tax year, rates start at 1.92% on the first roughly MXN 10,135 of taxable income and climb through multiple brackets to a top marginal rate of 35% on income above MXN 5,107,704.1Worldwide Tax Summaries. Mexico – Individual – Taxes on Personal Income ISR covers wages, self-employment earnings, business profits, rental income, investment gains, and most other revenue.
If you work for a Mexican employer, ISR is withheld from each paycheck automatically. Your employer calculates the monthly provisional amount and remits it. Self-employed individuals and those with income from several sources handle their own monthly provisional payments and reconcile at year-end.
How Non-Residents Are Taxed
Non-residents earning Mexican-source employment income use a separate rate schedule. The first MXN 125,900 of annual earnings is exempt. Income between MXN 125,900 and MXN 1,000,000 is taxed at 15%, and anything above MXN 1,000,000 is taxed at 30%. Other categories of Mexican-source income for non-residents, such as rental payments, royalties, or professional fees, may carry different flat withholding rates.
Non-resident rates can be higher or lower than the resident brackets depending on your income level, but non-residents can’t claim most deductions or credits available to residents. For a high earner, the flat 30% might beat the 35% resident top bracket; for a lower earner, resident brackets are almost always kinder.
Value Added Tax on Purchases
Nearly every purchase in Mexico includes the Impuesto al Valor Agregado (IVA), a consumption tax built into the price. The standard nationwide rate is 16%.2Leyes Federales. Ley del Impuesto al Valor Agregado Groceries, electronics, restaurant meals: the tax is already in what you pay at the register.
Certain essentials are taxed at 0%, which means the seller doesn’t add IVA and can still recover VAT paid on inputs. Basic food staples, prescription medications, and a handful of other priority goods fall into this category. If you run a business, the difference between “exempt” and “zero-rated” matters, because exempt transactions don’t allow input VAT recovery while zero-rated ones do.
Property Taxes
The annual property tax, called the Predial, is collected by municipal governments and based on the property’s cadastral (assessed) value rather than market value. Rates vary by municipality but generally fall between 0.05% and 0.4% of assessed value, which is low by North American standards. Many municipalities offer discounts of up to 25% for paying the full annual amount in January, and some give further reductions to seniors.
A separate one-time tax applies when a property changes hands. The Impuesto sobre Adquisición de Inmuebles (ISAI) is paid by the buyer at closing and typically ranges from 2% to 5% of the transaction value, depending on the state and municipality. Quintana Roo sits near the low end at around 2%; other jurisdictions charge more. Notary fees and other closing expenses stack on top, so budget above the listed price.
Social Security Contributions
Anyone formally employed in Mexico participates in the social security system run by the Instituto Mexicano del Seguro Social (IMSS). Both employer and employee contribute, though the system leans heavily on employers. Employer contributions generally range from 24% to 38% of the employee’s base salary depending on risk classification and wage level, while employee contributions are much smaller. These payments fund healthcare, disability insurance, retirement savings, and housing credits through Infonavit.
Self-employed people can voluntarily enroll in IMSS to access public healthcare and retirement benefits, though the contribution structure differs from the employer-employee model. Many self-employed expats and freelancers skip IMSS and buy private health insurance instead, which means forgoing contributions to the public pension system.
Registering with SAT and Getting an RFC
Mexico’s tax authority, the Servicio de Administración Tributaria (SAT), requires every taxpayer to register and obtain a Registro Federal de Contribuyentes (RFC) number.3Servicio de Administración Tributaria (SAT). Portal de Tramites y Servicios del SAT It functions like a Social Security number for tax purposes. Without one you can’t legally receive a paycheck from a registered employer, open a bank account, buy a vehicle, or sign a formal lease.
Foreigners register by booking an in-person appointment at a SAT office through citas.sat.gob.mx. You’ll need your immigration document (temporary or permanent resident card), proof of a Mexican address such as a utility bill or lease, and sometimes additional paperwork depending on your immigration status. Appointment availability can be tight in busy offices.
One limitation matters for expats. If you hold temporary residency without a work permit, SAT issues a restricted RFC that lets you open bank accounts and report investments but does not let you issue invoices or run a business. Work status has to come first.
Filing Deadlines and Annual Returns
The fiscal year runs on the calendar year. Individuals file their annual income tax return by April 30 of the following year. For the 2025 tax year, that means April 30, 2026. SAT typically opens its online filing portal in early April.
Not everyone has to file annually. If your only income is employment wages and your total compensation for the year doesn’t exceed MXN 400,000, you’re generally exempt because your employer’s monthly withholdings settle the account. The same goes if your only income is Mexican bank interest below MXN 100,000 a year.
Some taxpayers also submit monthly provisional declarations. This mainly applies to self-employed people, business owners, and residents whose salary comes from a non-resident employer, since no local company is handling the withholding. Monthly provisionals are due by the 17th of the following month and filed electronically through SAT’s portal.
Americans in Mexico and Double Taxation
Americans living in Mexico face overlapping obligations because the United States taxes its citizens on worldwide income regardless of where they live.4Internal Revenue Service. US Citizens and Residents Abroad Filing Requirements A U.S. citizen who is also a Mexican tax resident could technically owe both countries tax on the same income. The US-Mexico Income Tax Convention addresses this in several ways.
The main relief tool is the foreign tax credit. If you pay Mexican income tax on earnings, you can claim a dollar-for-dollar credit against your U.S. tax liability for the Mexican taxes paid by filing IRS Form 1116.5Internal Revenue Service. 2025 Instructions for Form 1116 Because Mexico’s top rate of 35% is close to U.S. rates, many Americans in Mexico find the credit eliminates most or all of their U.S. tax on Mexican-source income. The Foreign Earned Income Exclusion is another option for qualifying taxpayers, though you can’t use both the exclusion and the credit on the same income.
The treaty also sorts out which country taxes specific income types. Private pensions are taxable only in the country where the recipient lives, so a U.S. pension received by someone residing in Mexico is taxable only in Mexico. U.S. Social Security benefits work the opposite way and are taxable only in the United States, even if the recipient lives in Mexico.6Internal Revenue Service. United States – Mexico Income Tax Convention The treaty’s “saving clause” preserves each country’s right to tax its own citizens and residents, which is why Americans abroad still file U.S. returns and rely on credits rather than treaty exemptions.
Penalties for Missing the Rules
Mexico doesn’t treat non-compliance as a minor issue. Failing to report income or underreporting earnings can trigger fines of 55% to 75% of the omitted tax amount. Interest accrues on the unpaid balance from the original due date, so a missed payment grows quickly.
SAT has become more aggressive with enforcement technology over the past decade, cross-referencing RFC numbers against bank transactions, property registrations, and digital platform reports. If you have an RFC and a bank account, SAT can see discrepancies between reported income and financial activity. Fixing a late or incorrect filing proactively is almost always cheaper than waiting for SAT to ask questions.
