What are the tax implications of divorce in 2025?

Divorce has significant tax consequences that many people overlook. Your filing status depends on whether your divorce was finalized by December 31 of the tax year.

Filing status: If your divorce is final by December 31, you must file as Single or Head of Household (if you have a qualifying dependent). If the divorce is not yet final, you are still considered married and must file as MFJ or MFS. A legal separation under a decree of separate maintenance counts as unmarried in most states.

Alimony (post-2018 divorce agreements): Under the Tax Cuts and Jobs Act, alimony paid under divorce agreements executed after December 31, 2018 is not deductible by the payer and not taxable to the recipient. This was a major change from prior law. Pre-2019 agreements that have not been modified still follow the old rules (deductible/taxable).

Property division: Transfers of property between spouses (or former spouses incident to divorce) are generally tax-free under IRC Section 1041. This includes transferring the home, investment accounts, or retirement accounts. However, the receiving spouse takes the transferor's cost basis, meaning they may face capital gains when they eventually sell.

Retirement accounts: A Qualified Domestic Relations Order (QDRO) allows penalty-free transfer of 401(k) or pension funds to a former spouse. IRA transfers incident to divorce can be done by changing the name on the account or by direct transfer. These are not taxable events.

Claiming children: Only one parent can claim a child as a dependent. The custodial parent (where the child lives more nights) gets the default claim. The custodial parent can release the claim to the noncustodial parent using Form 8332.
