Can I Claim My Girlfriend as a Dependent?

Despite the name, a “qualifying relative” does not have to be related to you. For an unrelated person, the requirements are:

• She lived with you for the entire year as a member of your household
• Her gross income was under $5,300 for 2026
• You provided more than half of her total support
• She was not the qualifying child of another taxpayer
• She met the citizenship or residency requirement, and your relationship did not violate local law

Failing even one of these prevents the claim. The rest of this guide works through each test, with the examples that decide most real cases.

This is the biggest difference between claiming a girlfriend and claiming family. Parents, children, siblings, grandparents and certain in-laws satisfy the relationship requirement without living with you. A girlfriend is not on that list, so your home has to have been her household for the full year.

Moved in on 1 January and stayed through 31 December? That part of the test may be met. Moved in during June? Even if you paid every one of her expenses from that day on, the full-year requirement fails for that tax year. Certain temporary absences — education, illness, business, vacation, military service — can be treated differently from permanently living elsewhere.

The question is not whether she spent a lot of time at your place. It is whether your home was her household for the required period.

For 2026, a qualifying relative's gross income must be less than $5,300. The limit was $5,200 for 2025 — it is indexed for inflation and moves most years, so check the figure for the return you are actually filing.

This is the test that ends most cases. A girlfriend earning $15,000 cannot be your dependent even if you pay the rent, utilities, groceries and insurance — her income is simply over the line.

One detail that trips people up: gross income is not what lands in her bank account. The IRS means income in the form of money, property and services that is not exempt from tax. If you want to see the gap between the two for your own pay, the paycheck calculator breaks gross down to net line by line, and how much tax is taken from a paycheck explains each deduction.

Clearing the income test does not finish the job. You generally have to provide more than 50% of her total support for the calendar year. Support includes housing, food, clothing, medical and dental costs, transportation, education, recreation and other basic living expenses.

Housing carries a lot of weight. If she lives in a home you pay for, the value of that lodging counts toward the support you provide. The arithmetic is simply support you provided ÷ total support she received, and the result has to clear 50%.

Contribute $9,000 of that same $20,000 instead and your share is 45% — the test fails. Note that the denominator is her total support from every source, not just what the two of you spent, which is why parental contributions so often break this test.

She cannot be someone else's qualifying child

If your girlfriend is the qualifying child of another taxpayer, you cannot claim her as your qualifying relative instead. This comes up most with younger adults: a 21-year-old full-time student may still meet the requirements to be her parents' qualifying child, depending on her living situation. Who pays the bills is not the whole question.

Citizenship, residency, and local law

A dependent generally must be a U.S. citizen, U.S. national, U.S. resident alien, or a resident of Canada or Mexico, subject to the applicable exceptions. This matters if one partner recently moved to the United States, is an international student, or has nonresident status.

There is also a rule that gets almost no attention: for an unrelated person to qualify by living in your household, the relationship must not violate local law. Publication 501 gives the example of a partner who lived with the taxpayer all year but was married to someone else — the relationship violated state law, so the household test failed.

A girlfriend who qualifies as your dependent does not make you eligible for the Child Tax Credit. A qualifying relative may make you eligible for the Credit for Other Dependents, assuming the credit's own requirements are met. Credit amounts and income limits change, so check the rules for the year you are filing.

Claiming her also does not make you Head of Household by itself — those are separate tests, and an unrelated partner is not a qualifying person for that status.

Whether the claim changes your bottom line depends on your income, filing status and other credits. Run your numbers before and after with the take-home pay calculator, and if the answer changes your withholding, what a tax write-off actually does explains why a deduction and a credit move your bill by different amounts.

Being claimed does not stop her filing her own return, either. She may still need to file — or want to, to recover withholding — as long as the return reflects her dependent status correctly.

You should be able to show both where she lived and how you worked out that you provided more than half her support. A simple spreadsheet listing her total annual support and who paid each item is usually enough.

• Lease or housing documents showing a shared residence
• Utility bills, grocery and transportation costs
• Medical expenses and insurance payments you covered
• Bank or credit-card records
• Records of her income, and of any other support she received

You can potentially claim your girlfriend as a dependent, but only if she meets the qualifying relative requirements. In practice the full-year household test, the $5,300 income test and the support test decide almost every case. A partner who lived with you all year, earned very little and received more than half her support from you has a real chance; one with a regular full-time income or her own place does not.

Before filing, add up the support you actually provided and confirm her gross income for the year. The IRS's Whom May I Claim as a Dependent? interactive assistant gives a situation-specific answer, and Publication 501 is the underlying source for every rule on this page. The $5,300 figure comes from IRS Revenue Procedure 2025-32, which sets the § 152(d)(1)(B) exemption amount for 2026.
