Why Is My Tax Refund So Low in 2026?

If your refund looks smaller than it did a year ago, you're not imagining it. Average refunds have shifted noticeably since pandemic-era credits expired, and routine life events — a job change, a raise, a new dependent aging off — can quietly move thousands of dollars in either direction without you doing anything wrong. Here are the most common reasons 2026 refunds run below expectations and what you can do about each one.

Your withholding is now better calibrated

After the IRS redesigned Form W-4 in 2020, millions of workers who updated their forms switched from over-withholding to roughly accurate withholding. A smaller refund isn't a loss — you had more money in your pocket throughout the year instead of lending it to the government interest-free. If you changed jobs or updated a W-4 in the past two years, this is the most likely explanation.

A pandemic-era credit expired or phased down

• The expanded Child Tax Credit ($3,000–$3,600 per child) reverted to $2,000 after 2021. Households with two children lost up to $3,200 of refundable credit.
• The EITC boost for childless workers that applied in 2021 also expired.
• The above-the-line charitable deduction for non-itemizers ($300/$600) ended after 2021.

Your income went up

A raise or a side hustle can push more income into a higher bracket. Because withholding is calculated paycheck-by-paycheck against a projected annual rate, a mid-year raise may not be withhold at the correct blended rate for the full year. The result is often a smaller refund (or a balance due) even when you feel like you paid more tax.

You had a second income source

Freelance income, rental income, brokerage dividends, or a spouse returning to work are all withholding gaps. None of these sources automatically withhold federal tax at the right combined rate. If the IRS gets a 1099-NEC or a Schedule K-1 for income that wasn't in your W-4 calculation, you will owe — and a refund from wages may not be enough to cover it.

State withholding changed

Several states updated their withholding tables in 2024 and 2025. Some flat-rate states cut rates (like Georgia dropping to 5.39%), which means less state withholding, which means a smaller state refund even if your federal picture is unchanged. Check your most recent pay stub to see if state withholding dropped.

How to diagnose your specific situation

• Pull the last pay stub of the year and check year-to-date federal and state withholding.
• Run our IRS Tax Refund Calculator with that withholding figure and your actual income.
• If the estimated refund matches reality, your withholding is working as intended.
• If you're owed more than the calculator shows, you may have unclaimed credits — EITC, Child Tax Credit, education credits, or retirement savers' credit.

How to increase your 2026 refund (if you want to)

Submit a new W-4 requesting additional withholding in the extra withholding line (Step 4c). Every $100 extra per paycheck generates roughly $2,600 in added withholding over 26 pay periods. Alternatively, make a fourth-quarter estimated tax payment by January 15 to avoid any underpayment penalty.
