Frequently asked questions

Is Mexico or Portugal better for tax?

On income tax alone, Mexico has the lower effective rate at a $100,000 income (26.7% vs 35.6%). But the right answer depends on your income level, which special regime you qualify for, social security, and treaty relief — see the full comparison below.

Which has the lower tax-residency threshold, Mexico or Portugal?

Mexico treats you as tax resident after its own residence test (no simple day count), and Portugal after 183 days. But ties like a home, family or economic centre can trigger residency on fewer days — never rely on a day count alone.

Does Mexico or Portugal have a digital nomad visa?

Mexico has a dedicated nomad/remote-work visa (income requirement around USD 2,500 / month); Portugal has a dedicated nomad/remote-work visa (income requirement around EUR 3,680 / month). See the "Digital nomad visa" row below for the sourced detail.
