Recently Divorced: Filing Status Optimization

Your marital status on December 31 determines your filing status for the entire year. After divorce, you may qualify for Head of Household status instead of Single.

December 31 is the only date that matters: Your marital status on the last day of the year determines your filing status for the entire year. Divorced on December 30? You file as single (or head of household) for all of that year. Still legally married on December 31? You must file as married filing jointly or married filing separately, even if you lived apart all year.

Head of household vs. single -- the gap is real: If you have a qualifying dependent and paid more than half the cost of maintaining your home, you can file as head of household. The 2026 standard deduction is $24,150 for HoH versus $16,100 for single. The 12% bracket extends to $75,600 for HoH but only $50,400 for single. Over a career of post-divorce filing, this adds up substantially.

The "considered unmarried" exception: You may qualify to file as head of household even while still legally married if you lived apart from your spouse for the last six months of the year, paid more than half the household costs, and your home was the main residence for your dependent child.

The tradeoff: Filing status is not a choice -- it follows specific IRS tests. Getting it wrong triggers amended returns and potential penalties. A CPA can evaluate your exact situation on December 31 and determine which status applies.
