Why you might want to stop getting refunds

A tax refund means the IRS held your money interest-free for a year. If you get a refund every April, you're lending the government money you could have used to pay bills, build savings, or invest. The size of your refund is the gap between what you paid in taxes throughout the year and what you actually owed—and that gap is something you can close.

The goal is to adjust your withholding so that by December 31, the amount your employer has already sent to the IRS matches almost exactly what you'll owe. This takes some math, but it's doable, and the IRS gives you the tools to do it.

Key Takeaways

  • Your withholding is the amount your employer sends to the IRS from each paycheck, controlled by the W-4 form you fill out when hired.
  • The IRS Withholding Estimator (on irs.gov) calculates how many allowances or dependents to claim so you break even or owe very little.
  • Claiming more allowances reduces what your employer withholds; claiming fewer increases it.
  • You can change your withholding mid-year by submitting a new W-4 to your payroll department—you don't have to wait until next January.
  • If you have multiple jobs, side income, or investments, withholding becomes more complex and may require estimated tax payments instead.

Understanding withholding and the W-4 form

When you start a job, you complete a W-4 (Employee's Withholding Certificate). This form tells your employer how much federal income tax to remove from each paycheck. The more allowances or dependents you claim, the less gets withheld. The fewer you claim, the more gets withheld.

Most people claim allowances based on their filing status and number of dependents, but the form also lets you claim additional allowances if you have other income sources or expect to itemize deductions. Each allowance you claim reduces your withholding by a set amount per paycheck.

If you've been getting large refunds year after year, it usually means you claimed too few allowances when you filled out your W-4, so your employer has been withholding more than necessary.

Use the IRS Withholding Estimator to find your target

The IRS provides a free tool called the Withholding Estimator at irs.gov/taxes/individuals/tax-withholding-estimator. It asks about your income, filing status, dependents, other jobs, and expected deductions, then tells you exactly how many allowances to claim on your W-4 so you don't overpay.

To use it, gather your most recent pay stub, last year's tax return, and information about any spouse's income if you file jointly. The tool walks you through step by step and produces a number—the allowances you should claim. Write that number down.

The estimator is updated each year and accounts for tax law changes. If your situation has changed—you got married, had a child, took a second job, or your income shifted—run it again to recalculate.

Submit a new W-4 to your employer

Once you know your target allowances, fill out a new W-4 form and give it to your payroll or human resources department. You don't have to wait for January or for a job change—you can submit a new W-4 anytime during the year, and the change takes effect on your next paycheck.

The 2024 W-4 is simpler than older versions. It asks for your name, address, filing status, and number of dependents. There's also a section for "other income" and "deductions" if you need to fine-tune further. If you're claiming the number the Withholding Estimator gave you, fill that in the appropriate box and submit.

Keep a copy for your records. Your employer should confirm receipt and tell you when the change takes effect.

Adjust mid-year if your situation changes

You don't have to live with an overpayment all year. If you realize in June that you're on track for a $3,000 refund, submit a new W-4 in June and reduce your withholding for the rest of the year. The sooner you adjust, the more paychecks benefit from the change.

Common reasons to adjust mid-year: you got married or divorced, had a child, started a side business, received a large bonus, or your spouse started or stopped working. Each of these changes your tax picture and may shift how much you should withhold.

If you're unsure whether to adjust, run the Withholding Estimator again with your current-year information. It will show you whether you're on track to overpay or underpay.

What to do if you have multiple jobs or self-employment income

Withholding gets trickier when you have more than one W-2 job or self-employment income. Your employer at each job doesn't know about your other income, so each one withholds as if that's your only job. The result is often underwithholding across all jobs combined.

If you have two W-2 jobs, you can use the Multiple Jobs Worksheet (part of the W-4) or tell one employer to withhold extra by claiming zero allowances on that W-4. This forces that employer to withhold more, which can offset underwithholding at the other job.

If you have self-employment income, you typically can't adjust a W-4 to cover it. Instead, you may need to make estimated tax payments quarterly to the IRS (Form 1040-ES). These are payments you send directly to the IRS in April, June, September, and January to cover taxes on income your employer isn't withholding from.

Aim for zero or a small refund, not a debt

The goal isn't to owe money on April 15—it's to break even or get a small refund (under $100). If you adjust your withholding too aggressively and end up owing, you may face penalties and interest, especially if you owe more than $1,000.

The Withholding Estimator is designed to get you close, but life is messy. A spouse's bonus, an unexpected deduction, or a change in tax law can shift things. Aiming for a small refund is safer than aiming for zero and accidentally underpaying.

If you do owe when you file, you can adjust your withholding again for the next year to prevent it from happening again.

Frequently Asked Questions

Can I claim zero allowances to get a bigger refund?

Yes, but that's the opposite of what you're trying to do. Claiming zero allowances maximizes withholding and produces a larger refund. To reduce or eliminate your refund, you claim more allowances, which reduces withholding.

Do I have to tell my employer why I'm changing my W-4?

No. Your employer doesn't need a reason—they just need the new W-4 form. It's a routine administrative change. You don't have to explain your withholding strategy.

What if the Withholding Estimator says I should claim more allowances than I have dependents?

That's normal. The form lets you claim allowances for dependents, but also for other income, deductions, or tax credits. If the estimator says claim 5 allowances and you have 2 dependents, the other 3 are for other tax situations. Claim what the estimator tells you.

If I adjust my withholding in October, will it affect my 2024 refund?

Yes, but only for the paychecks from October through December. If you're already on track for a large refund by October, a late adjustment won't eliminate it entirely—but it will reduce it. The bigger impact will be on your 2025 refund if you keep the new withholding in place.

What happens if I claim too many allowances and owe money?

You'll owe the difference when you file your return. If you owe more than $1,000, you may also owe a penalty. Adjust your withholding again for the next year, or make estimated tax payments if you have self-employment income, to avoid underpaying again.
