Common Reasons Why Your Tax Refund Is So Low

Here are the most frequent reasons why your refund may be smaller—even though your income or tax situation seems similar to last year.

1. You Earned More Income This Year

Earning more in 2025 sounds great, but it also means you likely moved into a higher tax bracket. Higher income results in a higher overall tax liability, which means a smaller refund.

Example: If you earned $12,000 more this year, a portion of that income may be taxed at a higher rate, decreasing your refund.

Solution: Use the “Paycheck Withholding” calculator in QuickBooks Payroll or update your W-4 with your employer to adjust your withholdings.

2. Fewer Tax Credits or Deductions

Several tax credits have changed or expired for 2025 filings, including parts of the Child Tax Credit and Earned Income Tax Credit (EITC). Losing or reducing these credits directly lowers your refund amount.

Solution: Double-check your credits and deductions in QuickBooks:

• QuickBooks Online: Go to Taxes ➜ Income Tax ➜ Deductions and Credits.
• QuickBooks Desktop: Select Company ➜ Manage Taxes ➜ Review Deductions/Credits.

3. You Claimed "0" on Your W-4

If you claimed “0” allowances, it means your employer withheld more tax from your paycheck throughout the year. While this typically increases your refund, if your income rose or you had multiple jobs, the result could swing the other way due to under-withholding on secondary income.

Solution: Revisit your W-4 using the IRS Withholding Estimator or via QuickBooks Payroll settings to better align with your true tax liability.

4. Adjustments After Marriage

If you got married in 2025 and filed jointly for the first time, your combined income may have pushed you into a higher tax bracket. Additionally, certain deductions may have been reduced or phased out due to joint income levels.

Solution:

In QuickBooks Desktop: Employees ➜ Payroll Info ➜ Tax Setup ➜ Update Marital Status and Filing Status.

In QuickBooks Online: Payroll ➜ Employees ➜ Tax Details ➜ Filing Status.

5. Changes in Federal Withholding or Tax Law Updates

New filing thresholds and standard deduction adjustments for 2026 have slightly altered refund outcomes, especially for middle-income taxpayers. Employers may also have changed withholding tables mid-year, affecting your total withheld tax.

Solution: Review your Form W-2 totals in QuickBooks to compare how much tax was actually withheld versus last year.

6. Reduced Overpaid Amount or Tax Credits Expired

If you expected a refund carryover or didn’t have as many deductions such as mortgage interest, charitable contributions, or student loan interest, your refund could drop.

Solution: Track deductible categories in QuickBooks under Expenses ➜ Tags ➜ Assign relevant categories like “Mortgage” or “Education.”
