Dependents that are married?

MaxB213

my partner is currently 22, resides with their mother, is claimed on her taxes as she “provides majority financial support”. This is not likely to change during the next tax year. If we get married but do not file jointly, will it change her ability to claim them?

Probably not. But if you do file jointly (other than to claim a refund of withholding), neither of you can be claimed as a dependent.

Of course, even if you file separately, they must meet all of the other requirements to be claimed. If your partner is not a student or disabled, they can only be claimed as a qualifying relative, and their gross income must be less than $5300 in 2026. If you live in a community property state, marrying could increase their income.
