Of the five filing statuses, Head of Household (HoH) is the one people most often qualify for without realizing it — and the one people incorrectly claim without realizing they don't. Getting it right matters: HoH offers a noticeably larger standard deduction and more favorable tax brackets than Single, for taxpayers who meet a specific three-part test.

The Three Requirements
  1. You're unmarried, or "considered unmarried," on the last day of the year. Legally unmarried counts, but so does a specific IRS rule for married taxpayers who lived apart from their spouse for the last six months of the year and meet the other requirements below.
  2. You paid more than half the cost of keeping up your home for the year. This includes rent or mortgage, utilities, insurance, repairs, and groceries eaten at home — not clothing, education, medical care, or vacations.
  3. A qualifying person lived with you for more than half the year. Usually a child, but it can be another relative under specific rules. There's one notable exception: a dependent parent doesn't have to live with you at all, as long as you paid more than half the cost of keeping up their home.

The combination of a bigger standard deduction and wider brackets means an HoH filer with identical income to a Single filer will owe meaningfully less — often the single biggest filing-status difference available to an unmarried taxpayer.

A Worked Example

Two unmarried taxpayers each have $70,000 of wage income and no other adjustments. One files Single with a $16,100 standard deduction, leaving $53,900 of taxable income. The other qualifies for Head of Household with a $24,150 standard deduction, leaving $45,850 of taxable income — $8,050 less taxable income before even accounting for HoH's wider brackets, which lower the tax on that remaining income further still. The combined effect is real money, not a rounding difference.

Multiple Support Situations

Sometimes several people together provide more than half of a relative's support, but no single person provides more than half alone — commonly siblings jointly supporting an aging parent. In these cases, a multiple support agreement can let the group designate one qualifying contributor (someone who provided more than 10% of the support) to claim the dependent and, if the other requirements are met, Head of Household status — a narrow but useful provision for exactly this family situation.

One More FAQ

My ex and I alternate who claims our child each year — does that affect who can file Head of Household? Not automatically. The right to claim a child as a dependent (often alternated by agreement) is a separate question from who meets the Head of Household residency and support tests, which are based on where the child actually lived and who paid the household costs, not on which year it's "your turn" to claim the dependent.
