Smaller Tax Refund Next Year? Real Math Beyond $3,276

Will my tax refund be smaller next year?

For many workers, yes on average, but your own refund depends on whether your 2026 paycheck withholding changed. A refund is your own overpayment returned, so smaller is not automatically worse.

📊 Data Point: The average refund was $3,276 through May 8, 2026, versus $2,939 a year earlier (+11.5%) — Source: IRS filing-season statistics.

A Tax Foundation analyst told USA TODAY Network in July 2026 that refunds will likely normalize in 2027.

Why were 2026 tax refunds so big?

How a refund is calculated

A refund is what you paid in through withholding minus the tax you owe; for tax year 2025 the IRS did not update withholding tables for the new law. The law is the One Big Beautiful Bill Act (the IRS calls it the Working Families Tax Cuts).

🔍 How It Works: Refund = tax paid in − tax owed. In 2025, tax owed fell but tax paid in did not, so the gap came back as a refund.

What the IRS did and didn’t update in 2025

The IRS decided not to update 2025 withholding tables. Treat last spring as a one-time timing mismatch, not a bonus; see who gets a larger 2026 refund.

What changed in 2026 paychecks and tax breaks

For tax year 2026 the standard deduction is $16,100 for single filers, $32,200 for married couples filing jointly and $24,150 for heads of household.

2025 vs 2026 withholding setup

Item	2025	2026	Key Detail
Withholding tables	Not updated	Updated	Set paycheck withholding
Tips and overtime deductions	Current procedures	Via updated Form W-4	Not automatic
Standard deduction (single / joint / head of household)	$15,750 / $31,500 / $23,625	$16,100 / $32,200 / $24,150	Single filers gain $350

Standard deduction, side by side

The $350 single-filer increase is worth about $42 of tax at 12%, so the bigger swings come from the new deductions.

Who is most likely to get a smaller refund?

Direction depends on whether the new breaks apply to you and your withholding changed.

Did your withholding change in 2026?

Your situation	Refund vs. last spring	Why
Updated W-4 filed in 2026	Likely smaller	Break now in paychecks
Qualify, but no new W-4	May stay large	Break not in paychecks
No new break applies	Likely a modest change	2026 tables reflect the law

Tips, overtime and car-loan interest

Qualified tips are deductible up to $25,000 and overtime up to $12,500 ($25,000 joint), both phasing out above $150,000 modified adjusted gross income (MAGI), or $300,000 joint. Car-loan interest is deductible up to $10,000, phasing out above $100,000 ($200,000 joint).

Age 65+ and the senior deduction

The senior deduction is $6,000 per eligible person age 65 or older, phasing out above $75,000 MAGI ($150,000 joint). The 2026 Form W-4 worksheet covers all four breaks. Self-employed: paycheck tables don’t apply.

How to estimate next spring’s refund from a paystub

Estimated refund = your projected full-year federal withholding minus your estimated tax.

The four-step estimate

Project full-year federal withholding from your latest paystub.
Subtract the standard deduction and any qualifying deduction from wages.
Apply 2026 marginal tax bracket rates (single): 10% to $12,400, then 12% to $50,400.
Subtract that tax from projected withholding.

🔍 How It Works: Each deduction dollar comes off your top layer: at 12%, $8,000 of tips saves 12% × $8,000 = $960.

Worked example: standard deduction only

Hypothetical single filer: $60,000 wages, $5,460 projected withholding (an invented figure).

Taxable income: $60,000 − $16,100 = $43,900
Tax: 10% × $12,400 + 12% × $31,500 = $1,240 + $3,780 = $5,020
Refund: $5,460 − $5,020 = $440

Worked example: with $8,000 in qualified tips

Taxable income: $43,900 − $8,000 in tips = $35,900
Tax: $1,240 + 12% × $23,500 = $1,240 + $2,820 = $4,060
Refund: $5,460 − $4,060 = $1,400, which is $960 more

These hypothetical figures exclude credits, state tax, payroll taxes and other income. For more cases, see the full tax refund formula; to check your tax line, run your own numbers in the income tax calculator.

How to adjust your withholding before year-end

Use the IRS Tax Withholding Estimator

Gather your latest paystub and last year’s return.
Run the IRS Tax Withholding Estimator; it takes about 25 minutes on average and needs no login.

Update your Form W-4

If it suggests a change, complete a new Form W-4: Step 3 for credits, Step 4(b) for deductions, Step 4(c) for extra withholding.
Give the form to your employer. Preview take-home pay with the paycheck calculator.

What a late-year change can and can’t do

Fewer paychecks remain, so a change now is spread thinner; Publication 15-T suggests employers prompt a January W-4 refresh.

✅ Action Step: Ask a CPA or enrolled agent: “Given my jobs, filing status and other income, what W-4 setup avoids an underpayment penalty?”

Mistakes that turn a smaller refund into a tax bill

A smaller refund is not a higher tax. Cut $440 from Example A’s withholding and the refund is $0, yet the tax is still $5,020.

Cutting withholding too far

Withholding well below your tax can mean a balance due and an underpayment penalty. Match anticipated tax, not zero.

Forgetting a second job or spouse’s income

The IRS names multiple jobs and working spouses as reasons to use the Estimator.

Claiming a break you don’t qualify for

Phase-outs apply, and the tips deduction excludes certain specified service trades.

Spending the refund before you’ve checked

Plan around the Estimator’s result, not last spring’s check. Side income? See how to schedule estimated tax payments.

✅ Action Step: Ask a CPA or enrolled agent: “Do I owe an underpayment penalty if I lower withholding, and how should I set estimated payments for side income?”
