How to claim a parent living abroad as a dependent

The short version

A parent abroad is claimed as a qualifying relative. If they pass four tests, you claim them as a dependent and get the $500 Credit for Other Dependents. The four tests are: relationship, citizen/resident status, gross income, and support. Miss any one and you can't claim them — pass all four and you can.

Test 1 — Relationship (parents get a pass on living with you)

A parent is on the IRS list of relatives who do not have to live in your home — along with grandparents, siblings, aunts and uncles, nieces and nephews, and in-laws. So a mother living full-time in Guadalajara still satisfies this test. Only an unrelated person has to live with you the entire year to qualify.

Test 2 — Citizen or resident (this is the key that unlocks it)

The dependent must be a U.S. citizen, U.S. national, U.S. resident alien, or a resident of Canada or Mexico. That last phrase is the whole reason this works: a parent who is a resident of Mexico (or Canada) clears the test. A parent living in, say, Colombia or the Philippines would not — this specific carve-out only covers Canada and Mexico.

Test 3 — Gross income (the most common disqualifier)

Their gross income for the year must be less than $5,200 in 2025, or less than $5,300 in 2026. The catch that surprises families: this counts worldwide taxable income. A Mexican IMSS pension, rental income from a house back home, or wages all count toward the limit. Only fully tax-exempt income is left out.

Test 4 — Support (you pay more than half)

You must provide more than half of their total support for the year — lodging, food, medical care, and so on, measured in real dollars. Their own income spent on themselves counts on the "total support" side, so keep records of what you send and what you cover. Lower living costs abroad often make it easy to clear the half-way mark, but you need to be able to show it.

The ITIN step people forget

To actually take the $500 credit, your parent needs an SSN or ITIN, and it must be issued by your return's due date (including extensions). A parent who isn't eligible for an SSN gets an ITIN using Form W-7. This takes weeks, so start early — filing without their number means losing the credit for that year.

What it's worth

The Credit for Other Dependents is $500 per qualifying dependent, nonrefundable. It only starts to shrink if your AGI is over $200,000 (single or head of household) or $400,000 (married filing jointly), dropping $50 for every $1,000 above. For most working families the full $500 applies.
