Why you might want a smaller refund

A large tax refund means the IRS held more of your paycheck than necessary throughout the year. That money was yours all along — you simply lent it to the government interest-free. If you prefer to keep that money in your own account each month instead of waiting for a refund, you can adjust your withholding to reduce or eliminate your refund.

The most common reason to do this is cash flow. If you need money now rather than in April or whenever your refund arrives, adjusting your withholding puts that money back into your paychecks immediately. Some people also prefer to manage their own money rather than rely on a government refund.

Key Takeaways

  • You reduce your refund by filing a new W-4 form with your employer, which tells payroll how much tax to withhold from each paycheck.
  • The IRS provides a withholding calculator on its website that estimates how much you should withhold based on your income, deductions, and credits.
  • Changes to your W-4 take effect on your next paycheck, usually within one to two pay periods.
  • If you adjust your withholding too much and end up owing money at tax time, you can file an amended W-4 to correct it.

Use the IRS withholding calculator to find your target

The IRS Tax Withholding Estimator is the official tool for figuring out how much tax should come out of your paycheck. You can find it at irs.gov by searching "withholding calculator." It asks about your income, filing status, dependents, deductions, and any other income sources, then tells you what your withholding should be.

The calculator is most accurate if you have your most recent pay stub and last year's tax return in front of you. It takes about 10 to 15 minutes to complete. At the end, it will show you a number — that is the total federal tax that should be withheld from your paychecks for the year. If that number is lower than what is currently being withheld, you are getting a refund, and adjusting your W-4 will reduce it.

Fill out a new W-4 and submit it to payroll

Once you know your target withholding amount, you need to file a Form W-4 with your employer's payroll department. This form tells your employer how much federal income tax to withhold from each paycheck. You can get a blank W-4 from the IRS website or ask your payroll office for one.

The W-4 has several lines. Line 1 is your personal information. Lines 2 through 4 account for dependents and other credits. Line 5 is where you enter any additional withholding you want — or, if you want less withheld, you leave this blank or enter a negative number. The instructions on the form walk you through each step. If you are unsure, your payroll department can help you fill it out correctly.

Submit the completed W-4 to your payroll office in person, by email, or however your employer accepts documents. Keep a copy for your records. Your new withholding takes effect on your next paycheck, usually within one to two pay periods.

Understand the difference between withholding and deductions

Withholding is the tax your employer takes out of your paycheck before you receive it. Deductions are amounts you subtract from your income when you file your tax return — things like the standard deduction, mortgage interest, or charitable donations. Reducing your refund requires adjusting your withholding, not your deductions.

Some people confuse the two and try to change their deductions to reduce a refund. That does not work. Your deductions affect how much tax you owe overall, but your withholding affects how much is taken from your paychecks. To get more money in your paychecks now, you must adjust your W-4.

Monitor your paychecks after you submit the W-4

After you submit your new W-4, check your next few paychecks to confirm the withholding changed. Your pay stub will show federal income tax withheld — this number should be lower than before if you adjusted correctly. If it did not change, contact your payroll office to confirm they received and processed your W-4.

Keep track of how much is being withheld over the next few months. If you are still getting a large refund when you file your return, you can file another W-4 to adjust further. If you adjust too much and end up owing money, you can file a new W-4 mid-year to increase your withholding again.

What to do if you adjust too much and owe taxes

If you reduce your withholding too aggressively and discover at tax time that you owe money instead of getting a refund, you have options. You can pay the amount owed when you file your return. If you cannot pay in full, the IRS offers payment plans — you can set up a short-term plan (120 days or less) or a long-term installment agreement.

To avoid this problem next year, file a new W-4 immediately to increase your withholding. The sooner you correct it, the less you will owe at the end of the year. You can file a W-4 as many times as you need to throughout the year.

Special situations that affect withholding

If you have a spouse who also works, you may need to coordinate your withholding between both jobs. The IRS withholding calculator has a section for this. If you have income from self-employment, rental property, investments, or a side business, that income is not subject to withholding, so you may need to increase your withholding from your main job to cover the tax on that other income.

If your income or life circumstances changed — you got married, had a child, bought a home, or took a new job — you should run the withholding calculator again. These changes can significantly affect how much tax you should have withheld. The calculator will account for all of them.

Frequently Asked Questions

Can I reduce my withholding if I am self-employed?

Self-employed income does not have withholding. Instead, you pay estimated taxes quarterly to the IRS. You can reduce your estimated tax payments if you expect lower income, but you must do this through the IRS, not through an employer W-4. Contact the IRS or a tax professional for guidance on adjusting your quarterly payments.

How long does it take for a new W-4 to take effect?

Most employers process a new W-4 within one to two pay periods. Your next paycheck should reflect the new withholding amount. If it does not, contact your payroll office to confirm they received the form.

What if I have multiple jobs?

If you work more than one job, you should run the IRS withholding calculator and account for all your income sources. You can then adjust the W-4 at whichever job has the largest paycheck. Some people split the additional withholding between both jobs, but it is simpler to adjust just one.

Can I claim zero dependents to reduce my refund?

Claiming fewer dependents on your W-4 will increase your withholding, which makes your refund smaller — but this is an indirect method. Using the IRS withholding calculator and adjusting your W-4 based on the result is more precise and gets you to the right withholding faster.
