Filing Status Explained: Which One Are You?
Quick Answer
Your filing status determines your tax bracket thresholds, standard deduction amount, and eligibility for certain credits and deductions. The IRS has five filing statuses: Single, Married Filing Jointly, Married Filing Separately, Head of Household, and Qualifying Surviving Spouse. Choosing the right one can save you thousands of dollars in taxes each year.
The Five Filing Statuses
1. Single
You file as single if you are unmarried, divorced, or legally separated on December 31 of the tax year. This is the most straightforward status with the smallest standard deduction ($15,000 in 2025) and the narrowest tax brackets.
2. Married Filing Jointly
The most common status for married couples. Both spouses report all income on one return. You get the largest standard deduction ($30,000) and the widest bracket thresholds. See the full explanation or try the married calculator.
3. Married Filing Separately
Each spouse files their own return. The standard deduction is $15,000 (same as single), and bracket thresholds are half the joint amounts. This is usually less favorable but can help in specific situations. Learn when to file separately.
4. Head of Household
For unmarried taxpayers who pay more than half the cost of keeping up a home for a qualifying dependent. The standard deduction is $22,500 — larger than single but less than joint. Bracket thresholds are also more generous than single. See the full breakdown.
5. Qualifying Surviving Spouse
Available for two years after your spouse's death if you have a dependent child. You get the same benefits as married filing jointly ($30,000 standard deduction and wide brackets).
2025 Standard Deductions by Status

| Married Filing Separately | $15,000 |
| Head of Household | $22,500 |

Real Example With Actual Numbers
Compare how filing status affects taxes on $75,000 in gross income (after the applicable standard deduction):
| Status | Std. Deduction | Taxable Income | Federal Tax | Effective Rate |
|---|---|---|---|---|
| Single | $15,000 | $60,000 | $8,330 | 11.1% |
| Head of Household | $22,500 | $52,500 | $6,388 | 8.5% |
| Married Filing Jointly* | $30,000 | $45,000 | $4,996 | 6.7% |
*Assumes only one spouse earns income.
The difference between single and head of household on the same $75,000 is nearly $2,000 per year in federal tax savings. See your numbers at the SalaryHog calculator.
How to Determine Your Filing Status
Ask these questions in order:
- Are you married on December 31? If yes, choose between filing jointly or separately.
- Is your spouse deceased within the last two years and you have a dependent child? You may qualify as a qualifying surviving spouse.
- Are you unmarried and paying more than half the cost of a home for a dependent? You may qualify as head of household.
- None of the above? File as single.
Filing Status and Life Events
Your filing status often changes when life events happen:
- Getting married — Single to Married Filing Jointly
- Having a baby — May switch from Single to Head of Household (if unmarried)
- Divorce — Married to Single or Head of Household
- Spouse's death — Married Filing Jointly to Qualifying Surviving Spouse
