There could be a few reasons why your refund is less than expected this tax season. It’s possible that you entered the wrong number, put a decimal in the wrong spot when entering your information, or checked a box by mistake somewhere that resulted in an incorrect calculation. The lower refund might even be the result of a tax refund offset or unpaid debt.
Let’s take a deeper dive into some of the reasons your refund might be lower than expected and what steps you can take to boost your tax refund.
Why is my tax refund so low? 7 Reasons your refund might be smaller than expected
There are a few reasons why your refund is less than expected this tax season:
- Calculation mistakes
You may have entered the wrong numbers when reporting your wages and/or withholdings. Check the income and withholding sections of Form 1040 to make sure the wages and tax withheld you reported matches the amounts reported on your W-2 forms.
- Unpaid debt
If you have unpaid debt with a state or federal agency, the federal government can garnish your refund to pay off that debt. This includes past-due child support, state and federal income tax, and certain unemployment compensation debts.
If you owe taxes to the IRS from a previous tax year, those taxes will be reduced from any eligible tax refunds for the current year. The IRS will actually take payments for owed federal taxes from a previous year before any other federal or state agency under the Treasury Offset Program.
If you have questions about a delinquent debt that may have resulted in a lower tax refund, you can call The Treasury Offset Program at 800-304-3107 to find out which taxing agencies you owe the debt to. You will then need to contact that specific agency to discuss payment options yourself. Keep in mind that certain types of debt — including credit card debt — won’t be automatically offset by your tax refund.
- Standard deduction filing status
You may have checked the wrong box when claiming your standard deduction. The standard deduction varies based on your filing status, so selecting the right filing status is key.
4. Underpaid estimated taxes
If you’re self-employed and earned more than you expected to earn, you may have underpaid your estimated taxes. You can use a tax withholding calculator to figure out how much to pay in quarterly estimated tax payments for self-employed taxes.
5. Current withholding
The amount you’re withholding on your W-4 can affect your tax return, so make sure you’re withholding at least the amount you owe in taxes. If your personal or financial situation changes, use our W-4 calculator to determine the correct amount to withhold based upon your personal situation. You can then print and submit your new W-4 with your employer to make sure the correct amount is withheld.
6. IRS adjustments
While your tax return is being processed, the IRS cross-references the information on your tax return with the information they have on file for you. If there are any inconsistencies, the IRS will correct any differences and send you a letter of adjustment.
Some common errors that result in adjustments by the IRS include:
- Missing income, such as omitting interest income reported on a 1099-INT or forgetting to add a W-2 from a former job
- Transposed numbers or putting a decimal in the wrong spot
- Adjustments to certain deductions or credits
Sometimes these mistakes occur when you wait until the last minute to file because you’re rushing to make the filing deadline.
Another common issue that results in a lower tax refund are adjustments to credits or deductions because someone else claimed the same dependent on their tax return. If you provide over half of the support for your dependent and you’re eligible to claim them, make sure no one else is claiming them. Be informed and make sure you have accurate information for who you can claim as a dependent.
If applicable, have a discussion with your child’s other parent (if possible) about who can claim them as a dependent if you’re no longer together.
If the IRS adjusts your tax return, you’ll receive a Notice CP12 regarding the adjustments they made.
7. Treasury offset adjustment
It’s possible that your tax refund may have been reduced by the Treasury Offset Program. The Treasury Offset Program oversees the collection of overdue bills owed to federal and state agencies. Different federal and state agencies, such as the Department of Education and the Office of Child Support Services, submit delinquent debts that need to be collected. These debts are then paid off with tax refunds, which results in a lower tax refund amount.
It’s important to note that not all bills are subject to a tax offset. Bills from private lenders like a late car payment or missed cell phone bills will not reduce your tax refund.
Typically, the IRS will mail you a notice if your tax refund is different from the amount you claimed on your tax return. The notice will include information on the refund you were eligible for, the amount your tax refund was reduced by, what agency the money was sent to, and contact information for that agency.
If your refund is less than expected, you can check IRS Where’s My Refund, which will give you the most up-to-date information about your refund. The IRS will also send you a notice CP12 outlining why your refund was adjusted.
Ways to Save on Your Taxes Despite Tax Law Changes
While your return may be lower than expected, you can find ways to save on your taxes.
There are tax credits and deductions that can help increase your tax refund if you are able to itemize. Make sure you have picked up your mortgage interest and property taxes if you own your home, deduct all applicable business expenses from your self-employed income, and make sure you claim all credits you are entitled to. Missed write-offs and credits could mean money left on the table.
Even if you don’t have a lot of individual write-offs, many taxpayers are eligible for the standard deduction, which is adjusted for inflation. In 2023, it was:
- $13,850 single
- $20,800 Head of Household
- $27,700 married filing jointly
For 2024, the standard deduction has increased to:
- $14,600 single
- $21,900 Head of Household
- $29,200 married filing jointly
