If my dependent got marketplace insurance when she moved out of state and did not use my income, how do i report it?

[devilmannx6]

She moved mid year and used her income to qualify, do I still add her as a dependent for 6 months?

A dependent is a dependent for the whole year not for only a portion of the year.  There are two types of dependents, a qualifying child or a qualifying relative.

Both types of dependents have a support requirement that hinges upon support for the whole year, not a portion of the year.  See the definitions.

The tests for a qualifying child are:

• Relationship: Must be your child, adopted child, foster child, brother or sister, or a descendant of one of these (grand or nephew).
• Residence: Must have the same residence for more than half the year.
• Age: Must be under age 19 or under 24 and a full-time student for at least 5 months. They can be any age if they are totally and permanently disabled.
• Support: The dependent must not have provided more than half of their own support during the year.
• Joint Support: The child cannot file a joint return for the year.

The tests for a qualifying relative are:

• Qualifying Child: They are not the “qualifying child” of another taxpayer or your “qualifying child.”
• Gross Income: The dependent being claimed earns less than $4,700 in 2023.
• Total Support: You provide more than half of the total support for the year.
• Member of Household or Relationship: The person (a friend, girlfriend, non-blood relative) must live with you all year as a member of your household or be related to you.

The question is whether the individual may or may not be claimed as a dependent.  TurboTax software will ask you simple questions and give you the tax deductions and credits for which you are eligible based upon your answers.

If the the individual is a dependent, you will have to report health insurance for the whole year using an IRS form 1095-A from the dependent to report for the six months in another state.

If the individual is not a dependent, the dependent may file a tax return and report their own health insurance if they receive an IRS form 1095-A in addition to whatever health insurance you provided for the first six months.
