Who Qualifies for the Qualifying Surviving Spouse (QSS) Filing Status?
What the qualifying surviving spouse status is
Qualifying surviving spouse — abbreviated QSS on tax forms and in IRS instructions — is a federal filing status available for a limited time after a taxpayer's spouse dies. For years you can use it, it lets you keep the same tax brackets and standard deduction as married filing jointly, which are generally the most favorable of the five statuses. On older forms and in older articles you may see it called "qualifying widow(er) with dependent child" — the IRS renamed it, but the rules work the same way.
If you're new to how statuses work in general, start with our overview of what filing status means and why it matters.
The timeline: which years it covers
The status follows a specific calendar:
- The year your spouse dies: you generally may still file a joint return for that year, as long as you didn't remarry before the year ended. QSS is not used for this year — joint filing covers it.
- The two tax years after the year of death: these are the years QSS can apply, if you meet the requirements below.
- After that: QSS ends, and you file using whichever status you then qualify for — often head of household if you're keeping up a home for a dependent child, otherwise single.
The requirements
According to IRS Publication 501, which defines all five filing statuses, you can use QSS for a tax year only if all of the following are true:
- You were entitled to file a joint return with your spouse for the year they died (whether or not you actually filed jointly).
- You did not remarry before the end of the tax year in question. If you remarry, you file with your new spouse instead.
- You have a child or stepchild (not a foster child) whom you can claim as a dependent, subject to specific exceptions spelled out in Publication 501.
- That child lived in your home all year, apart from temporary absences such as school.
- You paid more than half the cost of keeping up the home for the year — rent or mortgage, utilities, food eaten in the home, and similar household expenses.
Each of these has fine print. The dependent-child rules in particular have exceptions, so it's worth reading the QSS section of Publication 501 or the filing-status chapter of Publication 17 rather than assuming.
What QSS actually changes
Filing status feeds into two big numbers: the standard deduction and the bracket thresholds. QSS uses the married-filing-jointly amounts for both, which are roughly double the single amounts. That means more of your income is sheltered by the deduction and more of it is taxed in the lower brackets before higher rates kick in. Our guide to how tax brackets work walks through why those thresholds matter more than the top rate you touch.
QSS does not change what income is taxable, and it doesn't by itself affect credits — though some credits have income limits that vary by status.
If you're not sure it applies to you
Edge cases are common here: a child who lived with a grandparent part of the year, a remarriage late in the year, a home you shared costs on. Rather than guessing, use the IRS's What Is My Filing Status? interactive tool, which asks a short series of questions about your year and tells you which status the rules point to. It's anonymous and takes a few minutes.
