Yes. Mexico does tax the worldwide income of its residents for tax purposes, meaning every peso and every dollar you earn anywhere on the planet can be reached by Mexican income tax at progressive rates that top out at 35%. Non-residents are a different story: they pay Mexican tax only on income sourced inside Mexico. The question that actually matters for most people, then, is whether they qualify as a Mexican tax resident in the first place, because the residency test is not a simple day-count and catches people who assumed they were safely outside it.
When Mexico Treats You as a Tax Resident
Under Mexico’s Federal Tax Code, the primary test is whether you have a home in the country. If you maintain a home in Mexico, you are a tax resident. There is no minimum number of days you need to spend there. The home is enough on its own.
If you also keep a home in another country, Mexico breaks the tie using your “center of vital interests.” You are a Mexican tax resident if either of these is true: more than 50% of your total income in a calendar year comes from Mexican sources, or Mexico is the main place where you carry out your professional activities. Only one of the two needs to apply.
Mexican nationals carry an extra burden. They are presumed to be tax residents and have to prove otherwise, typically by showing their home and center of vital interests sit in another country. And a Mexican national who moves to a jurisdiction Mexico classifies as a tax haven stays on the hook as a resident for the year of the move plus the following five years, unless Mexico has a tax treaty or an information-exchange agreement with that country.
What Counts as Worldwide Income
Once you are a resident, essentially every type of income is in scope, no matter where it is earned or paid.
- Salaries, wages, bonuses, and benefits from employers in any country.
- Business and self-employment profits from operations anywhere in the world.
- Rental income from properties inside or outside Mexico.
- Interest, dividends, and other investment returns from foreign or domestic accounts.
- Capital gains on real estate, stocks, and other assets, wherever those assets sit.
Cryptocurrency is treated as property rather than currency, so every sale, trade, or exchange is a taxable event. You calculate the gain by subtracting your original cost (including transaction fees and exchange commissions) from what you received on disposal. SAT generally expects first-in, first-out costing unless you keep detailed records supporting specific identification. Net crypto gains fold into your total annual income and are taxed at the same progressive rates as everything else.
What You Will Actually Pay
Mexico uses a progressive rate structure with 11 brackets. The rates climb steeply as income rises.1PwC. Mexico – Individual – Taxes on Personal Income For 2026, the key thresholds look like this:
- Up to MXN 10,135: 1.92%
- MXN 10,135 to MXN 86,022: 6.40% on the excess
- MXN 86,022 to MXN 151,176: 10.88% on the excess
- MXN 151,176 to MXN 210,404: 16.00% to 17.92% on the excess
- MXN 210,404 to MXN 668,840: 21.36% to 23.52% on the excess
- MXN 668,840 to MXN 1,276,926: 30.00% on the excess
- MXN 1,276,926 to MXN 5,107,704: 32.00% to 34.00% on the excess
- Over MXN 5,107,704: 35.00% on the excess
Each bracket also carries a base tax amount that accumulates as income moves through the lower tiers, so the headline percentage only applies to the slice of income above the threshold.
Relief From Double Taxation
Being taxed on worldwide income in Mexico does not mean you pay full tax to Mexico and full tax again to the country where the income was earned. Two mechanisms soften the overlap.
Tax Treaties
Mexico has a wide network of double taxation agreements, including with the United States and Canada. These treaties allocate taxing rights between the two countries and often cut the withholding rates that apply to cross-border dividends, interest, and royalties. If your foreign income comes from a treaty country, the treaty itself may already reduce what gets withheld at source.
Foreign Tax Credits
Treaty or no treaty, Mexican law lets you credit income taxes paid to a foreign government against your Mexican tax on the same income. The credit is capped per country at the amount of Mexican tax that would apply to that foreign-source income. If you paid a higher rate abroad than Mexico would charge on that slice, you can only offset up to the Mexican amount, and the excess is not usable against Mexican tax on income from somewhere else.1PwC.

If You Are a US Citizen Living in Mexico
The US-Mexico tax treaty contains a “savings clause” that lets the United States tax its own citizens on worldwide income as if the treaty did not exist. For a US citizen resident in Mexico, that means the IRS still expects a return and still taxes all your income. The treaty does not shield you from US tax.2Internal Revenue Service. Convention Between the United States and Mexico for the Avoidance of Double Taxation
Some treaty benefits survive the savings clause. The most important for most people is Article 24, which preserves double-taxation relief: you can still credit Mexican tax paid against your US liability on the same income, and the other direction too. Pensions, annuities, and government service income have their own carve-outs.2Internal Revenue Service. Convention Between the United States and Mexico for the Avoidance of Double Taxation
Deductions, Filing, and Leaving Residency
Mexico does not offer a standard deduction. Residents claim specific itemized deductions, most of which are limited in total to the lesser of 15% of annual income or five times the annual UMA (MXN 213,973 for 2026).3PwC. Mexico – Individual – Deductions The common items inside that cap include unreimbursed medical and dental expenses, health insurance premiums, inflation-adjusted mortgage interest, and charitable donations (capped separately at 7% of the prior year’s taxable income). Medical costs must be paid electronically; cash payments are rejected regardless of amount. Tuition for yourself, a spouse, children, or parents is deductible at per-student limits ranging from MXN 14,200 to MXN 24,500 depending on grade level, and university tuition does not qualify.
The annual return covering worldwide income is due April 30 of the year after the tax year. Six categories of otherwise non-taxable income must still be disclosed on the return for informational purposes: loan proceeds, prizes, gifts, inheritances, proceeds from selling a personal residence, and travel expense reimbursements. If SAT finds these amounts undisclosed, they can lose their exempt treatment and be reclassified as taxable.4Worldwide Tax Summaries. Mexico – Individual – Tax Administration
If you are planning to leave Mexico and stop being taxed on your worldwide income, file a formal notice of suspension of activities with SAT at least 15 days before your change of residency takes effect. Skip that filing and Mexico keeps treating you as a resident: you remain obligated to file annual returns reporting worldwide income, to make provisional tax payments at rates up to 35%, and to pay penalties for missed filings. Favorable balances you had built up can become unrecoverable.
