Filing Status

Filing status is the category a taxpayer selects on a federal income tax return, such as single or married filing jointly, which determines tax brackets, deduction amounts and credit eligibility.

What Is a Filing Status?

A filing status is a label a taxpayer chooses when preparing an income tax return. In the United States, the Internal Revenue Service recognizes five main filing statuses: single, married filing jointly, married filing separately, head of household, and qualifying surviving spouse. The status reflects a person's marital situation and family circumstances at the end of the tax year, and it tells the tax authority which set of rules applies to the return.

How It Affects Your Taxes

Filing status shapes several parts of a return. It determines the standard deduction amount, which is the fixed reduction applied to adjusted gross income for taxpayers who do not itemize. It also sets the income thresholds for each tax bracket, so the same income can be taxed at different effective rates depending on the status chosen. Some tax credit amounts and phase-out ranges also depend on filing status, and certain statuses are required for specific benefits.

Choosing a Status

Filing status depends on facts such as whether a person is married, whether they are supporting a dependent child, and whether a spouse has died in recent years. Married couples can usually choose between filing jointly and filing separately, and the two options often produce different results, so comparing them is a common step. Head of household generally requires being unmarried and paying more than half the cost of maintaining a home for a qualifying dependent. Taxpayers who are unsure of their status can review IRS publications or speak with a qualified tax professional.

Why It Matters to Investors

For investors, filing status affects how capital gains and dividends are taxed indirectly, because these amounts add to taxable income and fall into brackets set by filing status. Changes in marital status, such as marriage, divorce or the death of a spouse, can change which status is available for future returns, which may shift an investor's overall tax picture. Tax rules change over time, so the figures tied to each status should be checked against current IRS guidance.
