A worldwide-income jurisdiction with a progressive personal income tax and a statutory social-security charge — and a residency framework worth modelling before relocation.
Mexico applies a progressive personal income tax with a top marginal rate of 35%, alongside the country's social-security charge. The effective burden on $120,000 settles at 31.0%, leaving $82,809 in hand.
A walk through the four statutory channels by which Mexico claims part of a resident's gross compensation — followed by any special regime that overrides them.
4-bracket progressive system running from 2% to 35% on taxable income.
| Taxable income | Rate |
|---|---|
| up to 8,952 | 1.92% |
| 8,952 – 510,450 | 16.00% |
| 510,450 – 3,898,140 | 30.00% |
| over 3,898,140 | 35.00% |
On social security, employees pay 4.1%. Contributions are uncapped - high-income workers pay the full rate on every dollar.

Tax residency in Mexico is established by the jurisdiction's headline test[1]: physical presence of more than 183 days in a rolling twelve-month period, supplemented by 183+ days (tourist visa technically prohibits remote work). Spouses and unemancipated minors are typically presumed to share the residency of the principal earner unless rebutted.
Once resident, any special regime is not automatic. Most jurisdictions require a formal registration with the tax authority within a defined window following arrival, together with proof of qualifying activity and a lookback period of prior non-residency. Late registration forfeits the regime for the year in question and, in some cases, for the entire benefit window.[2]
The common pitfalls are predictable. Treaty interaction with the home state can override the local regime where the home jurisdiction asserts primary taxing rights — most relevantly, United States citizens remain subject to US federal tax on worldwide income, with foreign-tax-credit relief but no escape from the higher of the two bills. Activities undertaken before registration is approved may also fall outside the regime entirely.[3]

Healthcare financing on the resident side is normally embedded inside the social-security charge rather than carried as a separate payroll line. The Comparely engine models healthcare as part of the social contribution unless a country exposes a distinct line item — track additions in the schema for future surfacing.
