What it means
Filing status is the category a taxpayer selects at the top of a return, and it drives the standard deduction, the bracket thresholds and eligibility for several credits. Head of household sits between single and married filing jointly in how generous it is.
To qualify you must be unmarried or treated as unmarried on the last day of the tax year, have paid more than half the cost of maintaining your home, and have a qualifying person living with you for more than half the year. A dependent parent is the one exception, because a parent does not need to live with you provided you pay more than half the cost of their home.
For owner-managers and the self-employed, filing status changes the effective tax on every extra dollar of salary or distribution taken out of the business. Getting it right can move several thousand dollars a year, which matters when planning how to split remuneration between wages and profit distributions.
Only one person can claim head of household for the same qualifying child in the same year, so separated parents cannot both use it for one child. Two unmarried adults sharing an address can each file this way only if each genuinely maintains a separate household with a separate qualifying person.
In practice
Real-world examples.
Example
A marketing manager divorces and keeps the family home, where her eight-year-old lives for most of the year. She switches her payroll withholding from single to head of household and her monthly net pay rises by about $134, with the rest of the benefit arriving as a smaller balance due at filing.
Example
A shop owner pays more than half the cost of his mother's assisted living accommodation. Because a dependent parent does not need to share his home, he qualifies for head of household even though he lives alone.
Example
A bookkeeping firm reviews a new client's last three returns and finds he filed as single every year despite supporting a resident child. Amended returns recover the difference, and the firm builds a filing status check into its annual client questionnaire.
Formula
Calculation
Tax saving from the status = (head of household standard deduction - single standard deduction) x marginal tax rate, before counting any benefit from the wider brackets.
Take an illustrative year in which the standard deduction is $21,900 for head of household and $14,600 for single, and a self-employed consultant with $72,000 of adjusted gross income who supports one child.
Filing as single, taxable income would be $72,000 - $14,600 = $57,400. Filing as head of household, taxable income is $72,000 - $21,900 = $50,100. The difference of $57,400 - $50,100 = $7,300 taxed at a 22% marginal rate is a saving of 0.22 x $7,300 = $1,606 for the year, or roughly $1,606 / 12 = $134 a month in take-home pay once withholding is updated. The wider brackets available to this status add further saving on top.Case study
Seen in the real world.
Cedar Lane Bookkeeping is a fictional practice used here for illustrative purposes. Its owner noticed that several self-employed clients had defaulted to single filing simply because that was the box they ticked before they had children.
One client, a freelance photographer with $72,000 of income and a resident child, had filed as single for three years. Correcting the status recovered about $1,606 a year, or 3 x $1,606 = $4,818 across the three amended returns, less the practice's $600 fee for preparing them.
The practice then added two questions to its onboarding form: who lives in your home, and who pays more than half the cost of running it. The change cost nothing to implement and, over the following year, identified four more clients using the wrong status.
Watch out
Common mistakes.
- Assuming that simply having a child at home qualifies you, when the test is about paying more than half the cost of the household and being unmarried.
- Both separated parents claiming head of household for the same child, which will eventually be picked up and reversed.
- Treating child support received as household costs you paid, when only your own contributions count towards the more-than-half test.
Questions
People also ask.
Can I file as head of household if I am still legally married?
Possibly, if you lived apart from your spouse for the last six months of the year and meet the other tests, in which case you may be treated as unmarried.
Does the qualifying person have to be my own child?
No, it can be a grandchild, sibling, niece or nephew, or a dependent parent, provided the relationship and support tests are met.
Is the benefit only the bigger standard deduction?
No, the brackets are also wider than for single filers, so more income is taxed at each lower rate before the next rate applies.
