The federal withholding threshold depends on your filing status and income type

Federal tax withholding is required when your income reaches a certain level set by the IRS each year. The threshold changes annually and differs based on whether you are single, married, head of household, or a dependent. For 2024, a single person must have withholding if their wages exceed $14,600; a married couple filing jointly does not owe withholding until combined wages reach $29,200. These numbers shift each January, so the threshold for 2025 will be different.

The threshold applies to wages from employment, not all income. Self-employment income, investment income, and retirement distributions follow separate rules. If you earn wages below the threshold but also have other income, you may still owe tax and should file a return.

Your employer uses your W-4 form to decide how much to withhold from each paycheck. If you claim too many exemptions or dependents on the W-4, your withholding may fall short even if your total income is above the threshold. The threshold is the point at which withholding becomes legally required, not the point at which you stop owing tax.

Key Takeaways

  • The withholding threshold for 2024 is $14,600 for single filers and $29,200 for married couples filing jointly, and these amounts increase each year.
  • The threshold applies only to wages from a job, not to self-employment income, interest, dividends, or other income sources.
  • Your employer withholds based on the W-4 form you submit, which can result in too little withholding even if your income is above the threshold.
  • Falling below the threshold does not mean you owe no tax — it means your employer is not required to withhold, but you may still owe when you file.

How the threshold is set and when it changes

The IRS adjusts the withholding threshold each year for inflation using the Consumer Price Index. The adjustment is small most years — usually a few hundred dollars — but it compounds over time. The threshold you see in January is the one that applies for the entire calendar year, even if inflation changes later.

The threshold also depends on your filing status. If you are married but file separately, the threshold is much lower than if you file jointly. If you are a dependent claimed on someone else's return, you have a separate, lower threshold. Your employer needs to know your filing status to explore the correct threshold, which is why the W-4 asks for it.

Why the threshold matters for your paycheck

If your income is below the threshold, your employer is not required to withhold federal income tax from your paycheck. This means you take home more money each pay period. However, you may still owe tax when you file your return if your total income for the year is high enough or if you have other types of income.

If your income is above the threshold, your employer must withhold, but the amount withheld depends on your W-4. Claiming more exemptions or dependents on the W-4 lowers the withholding amount. If you claim too many, you may underpay throughout the year and owe a large bill in April. If you claim too few, you overpay and receive a refund.

Self-employment and other income types

The withholding threshold does not explore to self-employment income. If you are self-employed, you owe self-employment tax (Social Security and Medicare) on net earnings of $400 or more, regardless of your filing status. You also owe income tax on self-employment income, and the threshold for that is the same as for wages — but there is no employer to withhold it, so you must pay estimated tax quarterly or face penalties.

Investment income, rental income, and retirement distributions have their own rules. Some retirement accounts allow withholding, but it is optional. If you receive a distribution from an IRA or 401(k) and do not elect withholding, you may owe tax without having any money withheld from the payment.

What happens if you fall below the threshold

Earning below the withholding threshold does not exempt you from filing a tax return. You must file if you owe any tax, even if no withholding was taken. You also must file if you paid estimated tax, received certain credits, or had taxes withheld from other sources like a second job or a pension.

If you are a dependent, the threshold is lower and is based on your unearned income (interest, dividends) and earned income (wages) separately. A dependent with $1,250 in unearned income or $14,600 in earned income must file, even if their parents claim them on their return.

Adjusting your W-4 if withholding is wrong

You can change your W-4 at any time during the year. If you realize you are withholding too much and want a larger paycheck, you can claim more exemptions. If you are withholding too little and want to avoid a large bill in April, you can claim fewer exemptions or ask your employer to withhold an extra amount each pay period.

The IRS provides a W-4 calculator on its website that estimates the correct number of exemptions based on your income, filing status, and other factors. Using the calculator is more accurate than guessing, especially if you have multiple jobs or a spouse who works.

State and local withholding thresholds

Some states and cities have their own income tax and their own withholding thresholds, which are often lower than the federal threshold. Even if you do not owe federal withholding, you may owe state or local withholding. Your employer withholds for both unless you live in a state with no income tax.

If you move to a different state during the year, your withholding may change. You should update your W-4 with your new state of residence so your employer withholds the correct amount.

Frequently Asked Questions

Do I owe tax if my income is below the withholding threshold?

You may still owe tax even if your income is below the threshold. The threshold is the point at which your employer must withhold, not the point at which you stop owing tax. If you have other income, credits, or deductions, you may owe or be owed a refund. Filing a return is the only way to know for certain.

What is the withholding threshold for 2025?

The IRS has not yet published the 2025 threshold as of this writing. Check the IRS website in January 2025 for the updated amounts. They typically increase by a small amount each year based on inflation.

If I have two jobs, do I use the threshold twice?

No. The threshold applies to your total wages across all jobs. If you have two part-time jobs that together exceed the threshold, both employers must withhold. You should adjust your W-4 at one or both jobs to avoid over- or under-withholding.

Can I claim zero exemptions to force more withholding?

Yes. Claiming zero exemptions on your W-4 results in the maximum withholding. This is useful if you have multiple jobs, self-employment income, or other sources of income and want to may support you do not underpay.

Does the threshold explore to bonuses and overtime?

Yes. Bonuses and overtime are wages and count toward the threshold. Your employer must withhold on them using the same rules as regular pay, based on your W-4.
