Frequently Asked Questions

Q

How do I calculate my tax refund from my W-2?

Subtract the standard deduction from Box 1 wages to get taxable income, apply 2026 progressive tax brackets, subtract credits (child tax credit, EITC), then compare the result to Box 2 (federal withheld). If you withheld more than you owe, the difference is your refund.

  • Step 1: Box 1 wages minus pre-tax deductions (401k, HSA) = AGI
  • Step 2: AGI minus standard deduction ($16,100 single / $32,200 married) = taxable income
  • Step 3: Apply 2026 federal brackets (10% to 37%) progressively
  • Step 4: Subtract child tax credit ($2,000/child) and EITC if eligible
  • Step 5: Compare final tax to Box 2 withheld — positive difference = refund

Q

What W-2 boxes do I need for this calculator?

You need five key boxes from your W-2 form: Box 1 (wages), Box 2 (federal income tax withheld), Box 4 (Social Security tax), Box 6 (Medicare tax), and Box 17 (state income tax withheld). Box 12 codes D/W show 401(k) and HSA pre-tax contributions.

  • Box 1: Total wages, tips, and compensation — your gross taxable income
  • Box 2: Federal income tax withheld — determines your refund or amount owed
  • Box 4: Social Security tax (6.2% of wages up to $176,100)
  • Box 6: Medicare tax (1.45% of all wages, no cap)
  • Box 12 code D: 401(k) contributions that reduce your AGI
  • Box 17: State income tax withheld — varies by state (0% in TX/FL to 13.3% in CA)

Q

What are the 2026 federal tax brackets?

The 2026 tax brackets under the One Big Beautiful Bill Act range from 10% to 37%. For single filers: 10% on income up to $12,400, 12% up to $50,400, 22% up to $105,700, 24% up to $201,775, 32% up to $256,225, 35% up to $640,600, and 37% above that.

Q

What is the SALT deduction cap for 2026?

The state and local tax (SALT) deduction is capped at $40,400 for 2026 under the One Big Beautiful Bill Act, up from the previous $10,000 cap. This cap applies to the combined total of state income taxes, local taxes, and property taxes you can deduct when itemizing.

  • 2026 SALT cap: $40,400 (up from $10,000 in 2018–2025)
  • Includes state income tax + property tax + local taxes combined
  • Phase-out begins at $505,000 MAGI for single filers
  • Only applies if you itemize (standard deduction has no SALT limit)
  • High-tax states like CA, NY, NJ benefit most from the increased cap
Q

How does the Earned Income Tax Credit (EITC) work?

The EITC is a refundable tax credit for low-to-moderate income workers. For 2026, the maximum credit ranges from $649 (no children) to $8,046 (3+ children). Unlike other credits, the EITC can make your refund larger than your tax liability since it is fully refundable.

  • No children: max credit $649, income limit ~$19,500 (single)
  • 1 child: max credit $4,328, income limit ~$52,500 (single)
  • 2 children: max credit $7,152, income limit ~$59,500 (single)
  • 3+ children: max credit $8,046, income limit ~$63,400 (single)
  • Married filing jointly: income limits increase by ~$8,000
  • Not available for married filing separately
Q

Standard deduction vs itemized: which should I choose?

Choose whichever gives you the larger deduction. For 2026, the standard deduction is $16,100 (single) or $32,200 (married). Itemize only if your mortgage interest + SALT (capped at $40,400) + charitable + medical expenses exceed the standard deduction.

  • About 87% of taxpayers use the standard deduction
  • Standard deduction: $16,100 single, $32,200 married, $24,150 HoH
  • Age 65+: extra $2,050 (single) or $1,650 (married) standard deduction
  • Itemize if: mortgage interest + SALT + charity > standard deduction
  • This calculator auto-selects whichever method gives you the lower tax

Box 2: Federal Withheld$9,500
Box 17: State Withheld$3,750
Filing StatusSingle
StateCalifornia
Dependents0

Result

Estimated Refund$2,739
Federal Tax$7,849
California State Tax$2,662
Effective Rate14.0%

AGI = $75,000. Federal taxable income = $75,000 - $16,100 = $58,900. Federal tax from 2026 brackets: $12,400 x 10% + $38,000 x 12% + $8,500 x 22% = $7,850. CA tax on ($75,000 - $5,540) = $69,460 using CA progressive brackets = ~$2,662. Total liability $10,511 vs $13,250 withheld = ~$2,739 refund.

2Married Filing Jointly in Texas ($120,000 Wages, 2 Children)

Inputs

Box 1: Wages$120,000
Box 2: Federal Withheld$12,000
Box 17: State Withheld$0
Filing StatusMarried Filing Jointly
StateTexas (no income tax)
Children Under 172
401(k) Contributions$10,000

Result

Estimated Refund$5,306
Federal Tax$6,694
State Tax$0
Effective Rate5.6%

AGI = $120,000 - $10,000 (401k) = $110,000. Federal taxable income = $110,000 - $32,200 = $77,800. Federal tax: $24,800 x 10% + $53,000 x 12% = $8,840. Minus CTC: $8,840 - $4,000 = $4,840 (note: exact bracket calculation differs slightly). TX has no state tax. Total liability ~$6,694 vs $12,000 withheld = ~$5,306 refund.

Formulas Used

Federal Tax Liability (2026)

Federal Tax = Sum of (Taxable Income in Bracket × Rate) − Credits

Federal taxable income equals AGI minus deduction (standard or itemized). Tax is calculated progressively across 2026 brackets, then reduced by child tax credit and EITC.

Where:

AGI= Adjusted Gross Income = Box 1 wages minus pre-tax contributions (401k, HSA, IRA)
Standard Deduction= $16,100 (single), $32,200 (married), $24,150 (HoH) for 2026
Child Tax Credit= $2,000 per child under 17, phases out above $200k/$400k
EITC= Refundable credit up to $8,046 for low-to-moderate income workers

State Tax (Progressive Brackets)

State Tax = Sum of (State Taxable Income in Bracket × State Rate)

Most states use progressive brackets similar to federal. Nine states (AK, FL, NV, NH, SD, TN, TX, WA, WY) have no income tax. This calculator uses each state’s actual bracket structure.

Where:

State Taxable Income= AGI minus state-specific standard deduction (varies by state)
State Brackets= Progressive rates from 0% to 13.3% depending on state and income level

Refund or Amount Owed

Refund = (Box 2 Federal Withheld + Box 17 State Withheld) − (Federal Tax + State Tax)

Compares what was withheld from your paychecks to your calculated tax liability. A positive result means a refund; negative means you owe.

Where:

Federal Withheld= Box 2 on W-2: total federal income tax withheld during the year
State Withheld= Box 17 on W-2: total state income tax withheld during the year
