Formula
Tax Refund = Withholding − Tax Liability
Tax Liability = Tax on (Gross Income − Standard Deduction) using progressive brackets
2026 Standard Deduction: Single $15,000 | MFJ $30,000 | HoH $22,500
Example
Example: Single, $65,000 income, $8,500 withheld.
- Taxable Income: $65,000 − $15,000 = $50,000
- Tax: (10% × $11,925) + (12% × $36,550) + (22% × $1,525) = $6,677
- Withheld: $8,500 → Refund: $1,823
Frequently Asked Questions
- Subtract your standard deduction from gross income to get taxable income. Apply the tax brackets to calculate liability, then subtract your total federal withholding. If withholding exceeds liability, you get a refund.
- For 2026 (single filers): 10% up to $11,925; 12% up to $48,475; 22% up to $103,350; 24% up to $197,300; 32% up to $250,525; 35% up to $626,350; 37% over $626,350. Married filing jointly rates are roughly double the single thresholds.
- For 2026: Single = $15,000; Married Filing Jointly = $30,000; Head of Household = $22,500. These are the base amounts before any additional deductions for age or blindness.
- You may owe if you had self-employment income, multiple jobs, investment income, or if your W-4 was not set up correctly. Use the IRS withholding estimator to adjust your W-4 during the year.
- Contribute more to a 401(k) or HSA (reduces AGI), claim all eligible credits (Child Tax Credit, education credits, EITC), or increase withholding on your W-4. However, a large refund means you gave the IRS an interest-free loan.
