Divorce, legal separation, and ACA premium credits
Coordinate household changes, policy ownership, dependent claims, and APTC allocation after a relationship ends.
A final divorce or legal separation can change filing status, tax family, income, and who claims dependents. Update the Marketplace immediately and retain agreements needed to allocate a shared Form 1095-A.
Use the legal status at year-end
Federal tax status depends on whether a decree is final and on head-of-household rules, not merely a move to separate homes. Update addresses, household members, expected income, and which people remain on each policy.
Plan the dependency and policy allocation
If a policy covered people who end up in different tax families, the taxpayers may need to agree on allocation percentages or apply default Form 8962 rules. Preserve the decree, dependency release, and Marketplace statements.
Decision example and mistake
Former spouses leave a shared policy unchanged for several months and each assumes half the APTC. Form 8962 allocation is not automatically one-half. The mistake is canceling coverage retroactively without confirming the Marketplace effective date.
Assign policy amounts to the final tax households
Use the final divorce or separation date, dependent claims, and Marketplace policy records to determine who reports each person and month. A policy can remain shared after the tax households split. Form 8962 allocation rules, rather than who received the invoice, determine how premiums, benchmark amounts, and APTC move between returns.
Do not finalize either return until the former spouses' allocations collectively account for the policy's full premiums, benchmark amounts, and advance credits.
