What is the tax refund estimator 2026?

In short

A single filer earning $65,000 who withheld $8,500 and claims 1 child receives about a $5,080 refund ($48,900 taxable → $5,620 tax − $2,200 Child Tax Credit). The calculator uses 2026 IRS tax brackets, standard deductions ($16,100 single / $32,200 MFJ / $24,150 HOH), and the $2,200-per-child Child Tax Credit.

This tax refund estimator calculates your estimated federal income tax, applies the Child Tax Credit, and compares the result to your withholding to show whether you'll receive a refund or owe money at filing. It uses 2026 IRS tax brackets, standard deductions, and current CTC phase-out rules.

How to use this calculator

  1. 1Select your filing status (Single, Married Filing Jointly, Head of Household, or Married Filing Separately).
  2. 2Enter your W-2 wages from Box 1 of your W-2 form.
  3. 3Add any other income (interest, freelance, etc.) not subject to regular withholding.
  4. 4Enter federal income tax withheld from Box 2 of your W-2.
  5. 5Enter state tax withheld if you want to track that separately.
  6. 6Enter the number of qualifying children (under 17) for the Child Tax Credit.
  7. 7Choose standard or itemized deductions — if itemized, enter the total amount.

The formula

AGI=wages+other income
TI=AGI−max(std,itemized)
T=bracket calc(TI)
CTC=min(children × $2,000,T)
refund=W−(T−CTC)
AGI = wages + other income. Taxable income = AGI − standard deduction (or itemized, whichever is larger). Federal tax = bracket calculation on taxable income. Tax after credits = federal tax − Child Tax Credit (non-refundable). Refund = federal withheld − tax after credits.
AGI
— Adjusted Gross Income (wages + other income)
std
— Standard deduction for your filing status
TI
— Taxable income (AGI − deduction)
T
— Federal income tax from bracket calculation
CTC
— Child Tax Credit ($2,200/child for 2026, phases out above $200k/$400k AGI)
W
— Federal income tax withheld during the year
R
— Refund (positive) or amount owed (negative) = W − (T − CTC)

Worked example

The scenario

Single filer, $65,000 wages, $500 bank interest, $8,500 federal withheld, 1 qualifying child, using standard deduction.

gives

The result

AGI = $65,500. Taxable income = $65,500 − $16,100 = $49,400. Federal tax ≈ $5,680. Child Tax Credit = $2,200 (full, under $200k). Tax after credits = $3,480. Refund = $8,500 − $3,480 = $5,020.

Common use cases

  • Estimating your federal refund before you file your return
  • Deciding whether to adjust your W-4 withholding to avoid a large bill or refund
  • Planning how much to set aside if you have multiple W-2 jobs or self-employment income
  • Comparing how filing jointly vs. separately affects your refund for married couples

Limitations & assumptions

  • This estimator covers federal income tax only — it does not calculate state income taxes.
  • The Child Tax Credit here is the non-refundable portion only; the Additional CTC (refundable) is not included.
  • Does not account for other deductions (student loan interest, IRA contributions, HSA) or other credits (EITC, education credits).
  • Self-employment income and SE tax are not included — use the Self-Employed Tax Calculator for 1099 income.
  • Results are estimates only and should not replace filing software or a tax professional for complex situations.

Frequently asked questions

The IRS typically issues federal refunds within 21 days of accepting your electronically filed return. Paper returns take 6–8 weeks. The IRS 'Where's My Refund?' tool updates daily and gives you an exact status. State refunds have separate timelines — usually 4–8 weeks for e-filed returns.
