Tax residency
When Mexico taxes you
A visa lets you stay. It does not decide who taxes you. In Mexico that turns on a day count of about 183 days and the ties you keep, and it is the line that quietly reshapes what you take home.
When you become tax resident
Tax resident if centre of vital interests is in Mexico (over 50% of income Mexican-sourced or main professional base) or present 183+ days; residents taxed on worldwide income Mexico leads with a home/centre-of-vital-interests test rather than a pure day count; 183 days is a supporting trigger.
Centre of vital interests matters as much as the day count.

The trap below the day count
Staying under 183 days does not make you safe. A permanent home available to you, a partner or children living in Mexico, or your centre of vital interests can create residence well below the count. And where two countries both claim you in the same year, a tax treaty tie-breaker decides, on your permanent home first, then your centre of vital interests, then where you habitually live. This is the part worth taking to a specialist.
