Common reasons your refund dropped

Your refund is smaller this year because your tax situation changed in one of several concrete ways. The most common reason is that you earned more money but didn't have enough tax withheld from your paychecks — the IRS takes the difference out of your refund. A second reason is that you lost a tax credit you claimed last year, such as the Earned Income Tax Credit (EITC) or the Child Tax Credit, because your income rose or your household composition changed. A third is that you claimed fewer deductions or a smaller deduction than you did the year before.

Less commonly, a change in tax law itself reduced what you get back. The most recent example was the American Rescue Plan in 2021, which expanded the Child Tax Credit temporarily — that expansion ended after 2021, so families who claimed the larger credit that year saw smaller refunds in 2022. Your refund can also shrink if you had a major life event: marriage, divorce, a child born or adopted, or a dependent aging out of your household all change the credits and deductions you can claim.

Key Takeaways

  • A smaller refund usually means you had less tax withheld from your paychecks during the year, so the IRS took less back at tax time.
  • Tax credits like the EITC and Child Tax Credit shrink or disappear when your income rises or your household changes, directly reducing your refund.
  • Temporary tax law changes, such as the expanded Child Tax Credit that ended after 2021, can make this year's refund much smaller than last year's without any change in your personal situation.
  • You can adjust your withholding for next year by filing a new W-4 with your employer, which changes how much tax comes out of each paycheck.

How withholding affects your refund size

Withholding is the amount your employer takes out of each paycheck and sends to the IRS on your behalf. If your employer withheld less money this year than last year, your refund will be smaller — because there is less money for the IRS to return to you. This happens most often when you get a raise, take a second job, or have a spouse start working. Your employer calculates withholding based on the W-4 form you filled out, so if you didn't update it when your income changed, you probably had too little withheld.

The opposite is also true: if you had more withheld this year, your refund would be larger. Some people intentionally increase their withholding by claiming fewer allowances on their W-4, which forces their employer to take out more tax. They do this to get a larger refund, though it means less money in their paycheck each week.

Tax credits that disappeared or shrank

Tax credits are dollar-for-dollar reductions in what you owe, so losing a credit directly shrinks your refund. The Earned Income Tax Credit (EITC) is the most common one to lose. It phases out as your income rises — if you earned more this year, you may have lost some or all of it. The credit also depends on your filing status and whether you have dependents, so a change in either one can eliminate it.

The Child Tax Credit is another major one. In 2021, the American Rescue Plan temporarily increased it from $2,000 per child to $3,600 for children under six and $3,000 for children six to seventeen. That increase expired after 2021, so if you claimed the higher amount last year, your refund this year will be $1,600 to $2,000 smaller per child, even if nothing else changed. The credit also phases out when your income exceeds certain thresholds, which vary by filing status.

Other credits that can shrink or disappear: the American Opportunity Tax Credit (for education), the Lifetime Learning Credit, the Saver's Credit (for retirement contributions), and the Dependent Care Credit. Each has income limits and specific rules about who can claim it.

Deductions that changed or were lost

A deduction reduces your taxable income, so losing a deduction means you owe more tax and get back less. The most common change is the standard deduction, which the IRS adjusts every year for inflation. If you took the standard deduction last year and this year, the amount is different — but this usually makes your refund slightly larger, not smaller, because the standard deduction typically rises each year.

If you itemize deductions instead of taking the standard deduction, a smaller refund usually means your itemized deductions were smaller this year. This can happen if you paid less in state and local taxes (SALT), had fewer mortgage interest payments, or gave less to charity. It can also happen if you hit the $10,000 SALT cap — you can only deduct up to $10,000 in state income tax, property tax, and sales tax combined, so if you paid more than that, the extra doesn't help you.

Life changes that affect your refund

Marriage, divorce, and children all change your tax situation. If you got married and filed jointly for the first time, your refund may be smaller because you are now combining two incomes, which can push you into a higher tax bracket or cause you to lose credits that phase out at higher income levels. If you got divorced, you may have lost the ability to claim certain dependents or file as head of household, both of which can reduce your refund.

A child born or adopted during the year adds a dependent to your return, which usually increases your refund because of the Child Tax Credit. The opposite is true when a dependent ages out — typically at eighteen or twenty-four if they are a full-time student. Losing that dependent means losing the credit, which shrinks your refund. A dependent can also age out of the EITC, which has its own age limits depending on the type of dependent.

How to check what changed on your return

The IRS does not send you a detailed breakdown of why your refund changed, so you have to compare your returns yourself. Pull up last year's tax return and this year's and look at these lines: your total income, your standard or itemized deduction, your taxable income, and the credits you claimed. If any of these are different, that is where the change is.

If you used tax software both years, you can often see a side-by-side comparison. If you used a tax professional, ask them to walk you through the differences. If you filed by hand, you can download both returns from the IRS website using your account at IRS.gov — log in, go to "Tax Records," and select "Return Transcript." The transcript shows the key numbers from your return in a simple format.

Adjusting your withholding for next year

If your refund is smaller because you had too little withheld, you can fix it for next year by filing a new W-4 with your employer. The W-4 tells your employer how much tax to take out of each paycheck. You can file a new one at any time — you do not have to wait until January. The form is free and takes about ten minutes to complete.

The IRS has a withholding calculator on its website at IRS.gov/W4App that walks you through the questions and tells you what to enter on the form. Bring the completed form to your HR or payroll department, and the new withholding will take effect on your next paycheck. If you have a spouse who also works, they can file their own W-4 to adjust their withholding too.

Frequently Asked Questions

Can the IRS change my refund after I file?

Yes, if the IRS finds an error on your return, it will correct it and adjust your refund. This can make your refund smaller or larger. The IRS will send you a notice explaining the change. If you disagree, you have the right to contest it by following the instructions in the notice.

What if I owed taxes last year but got a refund this year?

This means your tax situation changed significantly — you may have had much more withheld, lost income, or gained a major credit. Compare the two returns to find the source. If you are unsure, a tax professional can walk you through the differences.

Does getting married affect my refund?

Yes. Filing jointly usually changes your tax bracket, deductions, and credits compared to filing single. Your combined refund as a married couple may be larger or smaller than the sum of what you would have gotten filing separately, depending on your incomes and credits.

Should I change my W-4 if my refund is too small?

If you want a larger refund, you can claim fewer allowances on your W-4, which increases the tax withheld from each paycheck. This gives you a larger refund but less money in your pocket during the year. The choice depends on whether you prefer a larger refund or larger paychecks.

Where can I find my previous tax returns?

Log into your IRS account at IRS.gov, go to "Tax Records," and select "Return Transcript." You can also call the IRS at 1-800-829-1040 and request a transcript by mail, which takes about five to ten business days.
