Filing Status Explained: The Five Options
Filing status affects tax brackets, the standard deduction, and eligibility for many credits. Choosing correctly is one of the first steps in preparing a return.
The five statuses
Single applies to unmarried taxpayers who do not qualify for another status. Married filing jointly combines both spouses' income on one return. Married filing separately keeps each spouse's return apart, and usually costs more tax because several credits are limited or unavailable.
Head of household is for unmarried taxpayers who pay more than half the cost of keeping up a home for a qualifying person. Qualifying surviving spouse can apply for two years after a spouse's death when the taxpayer supports a dependent child.
The year-end rule
Marital status is generally determined on the last day of the tax year. A couple who marry on December 31 are treated as married for the whole year. A couple with a final divorce decree by that date are treated as unmarried for the whole year.
When more than one status fits
Married couples can often calculate the return both ways. Joint filing usually wins, but separate filing can help when one spouse has large medical costs, income-driven student loan payments, or concerns about liability for the other spouse's tax.
Key takeaways
- Status is usually set by marital position on December 31.
- Head of household requires a qualifying person and paying most household costs.
- Couples should compare joint and separate results when in doubt.
