For the 2026 tax year, a married couple filing jointly can earn up to $32,200 in gross income before the IRS requires them to file a federal return.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 That figure is the joint standard deduction, and it doubles as the general filing threshold because income below it isn’t taxed. Several situations raise the threshold, lower it, or override it entirely, so the $32,200 number is where the analysis starts, not where it ends.
How the $32,200 Threshold Works
The standard deduction is the portion of income the federal government doesn’t tax. If your combined gross income for the year stays below it and neither spouse has a special filing obligation, you don’t need to submit a return. Gross income here means income from all sources before deductions, not what shows up on a W-2 after withholding.
When one or both spouses are 65 or older or legally blind at the end of the tax year, the IRS adds an extra amount to the standard deduction for each qualifying condition.2Office of the Law Revision Counsel. 26 USC 63 – Taxable Income Defined Each addition raises your filing threshold by the same amount. A couple where both spouses are 65 or older would add two additional amounts on top of the $32,200 base. The exact additional amount is set by the IRS inflation adjustments announcement each year.
When You Have to File Even Below $32,200
Several situations force a return even if your household income falls well under the threshold. The one that catches the most couples off guard involves side income. If either spouse has net self-employment earnings of $400 or more, you must file, regardless of total household income.3Internal Revenue Service. Self-Employed Individuals Tax Center Self-employment tax covers Social Security and Medicare separately from income tax, and the IRS needs a return to calculate it.
Other triggers include owing household employment tax, receiving advance premium tax credits through the Health Insurance Marketplace, and owing taxes on an IRA or health savings account distribution. None of these care about whether your income hits the standard deduction.
Why You Might Want to File Anyway
Even when a return isn’t required, filing one often puts money back in your pocket. Refundable credits like the Earned Income Tax Credit only pay out if you file to claim them. For 2026, married couples filing jointly with three or more qualifying children can claim the EITC with income up to roughly $70,000, and couples without children still qualify at lower income levels.1Internal Revenue Service.

Skipping a return because nothing is owed can mean walking away from money you’re entitled to.
Filing Separately Changes Everything
The $32,200 threshold assumes you file jointly. Choosing Married Filing Separately drops the filing threshold to just $5 of gross income.4Internal Revenue Service. Check If You Need To File a Tax Return That’s not a typo. The standard deduction on a separate return is $16,100, half the joint amount, and the tax brackets are compressed accordingly.1Internal Revenue Service.

There’s a further trap. If one spouse files separately and itemizes deductions, the other spouse’s standard deduction drops to zero, forcing them to itemize too even if their itemized total is smaller than the standard deduction would have been.2Office of the Law Revision Counsel. 26 USC 63 – Taxable Income Defined Filing separately also disqualifies you from the EITC, education credits, and the student loan interest deduction, and it lowers the child tax credit phaseout. The status makes sense in narrow situations, such as when one spouse has large medical expenses tied to a lower AGI, or when separating tax liability matters more than the tax savings. For most couples it costs more than filing jointly.
What Happens If You Should Have Filed and Didn’t
If your income exceeded the threshold and you didn’t file, the IRS charges a failure-to-file penalty of 5% of unpaid tax for each month or partial month the return is late, up to a maximum of 25%.5Office of the Law Revision Counsel. 26 USC 6651 – Failure To File Tax Return or To Pay Tax A separate failure-to-pay penalty of 0.5% per month runs alongside it if you also owe tax, though the filing penalty is reduced by the payment penalty amount when both apply for the same month.
If you’re more than 60 days late, the minimum penalty is the lesser of $435 or 100% of the tax due.5Office of the Law Revision Counsel. 26 USC 6651 – Failure To File Tax Return or To Pay Tax Interest accrues on top of both penalties. Filing late when you owe nothing avoids all of this, which is why couples genuinely below the threshold face no consequences for not filing. Those above it who ignore the deadline watch the costs climb quickly.
