Marriage, Divorce & Tax Planning: Filing Status Is Only the Beginning

Marriage and divorce change filing status, household composition, property ownership, support obligations, retirement assets, ACA coverage and business interests. Filing status is the first question, not the last.

Determine marital status under applicable law

Federal filing status generally turns on marital status at year-end, with special rules for certain separated spouses and surviving spouses. State law and court orders can affect property but do not automatically determine every federal tax result.

Compare joint filing with separate liability

A joint return can produce tax benefits but also joint and several liability. When facts create collection, compliance or disclosure concerns, consider the consequences rather than defaulting to the lowest combined tax.

Property transfers can be tax-deferred without being tax-free forever

Section 1041 generally prevents current gain or loss on qualifying transfers incident to divorce, but the transferee often takes carryover basis. The future tax burden can therefore follow the asset.

Retirement transfers require the right instrument

Qualified-plan divisions may require a QDRO; IRA transfers incident to divorce follow a different statutory path. A distribution followed by an informal payment can produce avoidable tax.

Children, ACA and business interests need separate coordination

Dependency, child tax benefits, Marketplace credits, S corporation ownership, partnership interests and basis should be reviewed under the final agreement. The tax practitioner should identify tax consequences without drafting the legal settlement.
