How to Be Exempt From Taxes: W-4, Income Limits, and Exclusions

You are exempt from federal income tax when your gross income for the year stays below the standard deduction for your filing status, and if you are an employee who expects zero tax liability, you can stop federal income tax withholding from your paychecks by writing “Exempt” on Form W-4. That is the whole mechanism for how to be exempt from taxes at the federal level: an income floor sets whether you owe anything, and the W-4 tells your employer to stop pulling income tax out of each check. Social Security and Medicare are a separate matter, and they keep coming out regardless.

Income Levels That Make You Exempt

The IRS sets a gross income floor for each filing status. Fall below it and you have no federal income tax liability and no obligation to file a return. The floor tracks the standard deduction closely, because once the deduction wipes out your income there is nothing left to tax. For tax year 2025:

Single, under 65: $15,750
Single, 65 or older: $17,550
Head of household, under 65: $23,625
Head of household, 65 or older: $25,625
Married filing jointly, both under 65: $31,500
Married filing jointly, one spouse 65 or older: $33,100
Married filing jointly, both 65 or older: $34,700
Married filing separately: $5 or more

The married-filing-separately number is not a typo. If your spouse itemizes, you have to file with as little as $5 in gross income.¹

Two boundaries matter here. Dependents follow a different set of thresholds because their standard deduction is smaller, so a working teenager or a college-age dependent with investment income may need to file even at low dollar amounts.² And self-employment has its own floor: net earnings of $400 or more trigger a filing requirement and self-employment tax at 15.3%, even when your total income is well under the standard deduction.³ A rideshare driver making $8,000 owes no income tax but still owes roughly $1,130 in self-employment tax.

How to Claim Exempt on Form W-4

If you are a W-2 employee and expect to stay below the threshold, you can stop federal income tax from being withheld each pay period. The catch is that both of the following must be true:

You had zero federal income tax liability last year. Either your total tax on Form 1040, line 24 was zero, or you were not required to file at all.
You reasonably expect zero liability this year.

Both tests apply at the same time.⁴ A college student who earned $6,000 last year and expects similar pay this year qualifies. Someone who had a light year because of a layoff but is now back at full salary does not.

Filling Out the Form

On Form W-4, write “Exempt” in the space below Step 4(c). Complete Steps 1(a), 1(b), and 5. Leave everything else blank, then give the form to your employer.⁵ Your employer has to put the change into effect no later than the start of the first payroll period ending on or after the 30th day after you turned in the form.⁴ Check a pay stub after that window to confirm income tax withholding has dropped to zero.

You Have to Renew It Every Year

Exempt status does not carry over. You have to submit a new Form W-4 claiming exempt by February 15 of the following year. If February 15 falls on a weekend or holiday the deadline moves to the next business day, which is February 17 for 2026. Miss the deadline and your employer will begin withholding as if you were single with no adjustments.⁴

What Exempt Status Does Not Cover

Claiming exempt on Form W-4 only affects federal income tax withholding. Your employer will keep taking out 6.2% for Social Security and 1.45% for Medicare from every paycheck. The W-4 has no effect on those payroll taxes.⁵

It also does not shield you if you were not eligible to claim it. If you write “Exempt” without a reasonable basis, the IRS can impose a $500 civil penalty for a false withholding statement, on top of the income tax you actually owe.⁶

Why You Might Want to File Anyway

Being below the filing threshold means you do not have to file. It does not mean you should not. Refundable tax credits pay out as a refund even when you owe zero tax, but only if you file a return to claim them.⁷

The Earned Income Tax Credit is the big one for low-income workers. For tax year 2025 the maximum EITC ranges from $649 with no qualifying children to $8,046 with three or more children.⁸ Other refundable credits include the Additional Child Tax Credit (up to $1,700 per qualifying child for 2025), the refundable portion of the American Opportunity Tax Credit for college students (up to $1,000), and the Premium Tax Credit for Marketplace health insurance.⁷ Filing is free through IRS Free File if your adjusted gross income is $89,000 or less, and through Free File Fillable Forms at any income level.⁹

Other Ways to Be Exempt From Federal Tax

A few specific situations create their own exemptions, separate from the income-threshold rule.

Foreign Earned Income Exclusion

U.S. citizens and residents working abroad can exclude up to $130,000 in foreign earnings for tax year 2025 and $132,900 for 2026.¹⁰ You have to either be a bona fide resident of a foreign country for a full tax year or be physically present in a foreign country for at least 330 full days during any 12-month period.¹¹ Claim it on Form 2555 with your return.

Members of Certain Religious Groups

Members of recognized religious groups conscientiously opposed to insurance benefits can apply to be exempt from Social Security and Medicare taxes by filing Form 4029. The group has to have existed continuously since December 31, 1950, provide a reasonable standard of living for its dependent members, and oppose both public and private insurance. Approval exempts you from those payroll taxes only, not from federal income tax, and it permanently waives your right to Social Security and Medicare benefits.¹²

Clergy Housing Allowance

Ministers of the gospel can exclude from gross income either the rental value of a home provided by their congregation or a housing allowance used to rent or buy a home, up to the fair rental value of the property including furnishings and utilities.¹³ The exclusion applies to income tax but not to self-employment tax.

What Happens if You Claim Exempt and You Should Not Have

Getting this wrong creates two separate problems. You will owe the income tax that should have been paid, plus interest. The IRS charges 7% annual interest on underpayments as of early 2026.¹⁴

You may also face an underpayment penalty. You avoid it if your total tax due is less than $1,000, or if you paid at least 90% of the current year’s tax (or 100% of the prior year’s tax, whichever is smaller) through withholding or estimated payments. If your adjusted gross income exceeded $150,000 in the prior year, the prior-year safe harbor rises to 110%.¹⁵ The safest move if you are unsure whether your income will stay below the threshold is to let normal withholding continue and take any overpayment back as a refund.
