How to read your results

Federal Tax Before Credits

Review this figure alongside gross income and the local tax rules that apply to you. It is a planning estimate, not a filing result.

State Tax Before Credits

Review this figure alongside gross income and the local tax rules that apply to you. It is a planning estimate, not a filing result.

Combined Tax Before Credits

Review this figure alongside gross income and the local tax rules that apply to you. It is a planning estimate, not a filing result.

Income Less Estimated Tax

Review this figure alongside gross income and the local tax rules that apply to you. It is a planning estimate, not a filing result.

Effective Rate

The effective rate lets you compare options on a like-for-like basis rather than being misled by different compounding periods or fee structures.

Method & assumptions

Annual 2026 income-tax estimate before credits for single and married-filing-jointly residents. Federal brackets and standard deductions use IRS 2026 figures. California uses the indexed 2026 schedules published in FTB October Tax News ($5,900/$11,800 standard deductions) plus the 1% Behavioral Health Services Tax on taxable income above $1 million. This is an annual bracket estimate, not the separate 540-ES payment worksheet which instructs use of prior-year schedules.

New York uses the 2026 IT-2105-I schedule, $8,000/$16,050 standard deductions, and the applicable benefit-recapture worksheets above $107,650 NY AGI, using the printed schedule base amounts and four-decimal phase-in ratios. Displayed estimates retain cents; filed/payment amounts follow NY whole-dollar instructions. The state AGI adjustment affects only the state model; enter differences between gross income and state AGI. Federal income assumes gross equals federal AGI. Texas, Florida and Washington impose no individual wage income tax in this model. WA capital-gains excise tax is outside this wage-income model.

Excludes exemption/tax credits, itemized deductions, dependent status, city taxes, NYC/Yonkers, MCTMT, FICA, SDI, AMT, capital gains and special-income treatment. The result is not total liability or paycheck net pay; use official return instructions for those.

Common mistakes

  • Using an assumption that is not supported by a current local quote, bill, statement or official source.
  • Treating a generic estimate as a lender, provider, payroll or tax authority decision.
  • Mixing monthly and annual inputs without converting them consistently.
  • Testing only one scenario instead of checking how a cautious assumption changes the result.

What to do next

  • Run a second scenario with a cautious assumption so you can see the downside clearly.
  • Compare the result with the related calculators below before making a decision.
  • Check current local rules, eligibility and provider terms before applying or committing money.
  • Keep a record of the assumptions so you can update the estimate when a quote, bill or pay figure changes.

Federal + state tax for California, New York and Texas โ€” how the estimate works

Guidance reviewed 1 October 2026

State income tax is levied on top of federal tax. In this calculator federal tax is estimated from IRS 2026 brackets and the standard deduction ($16,100 single / $32,200 MFJ). State tax uses graduated brackets for the five modeled states: California (up to 12.3%, plus 1% above $1,000,000), New York (up to 10.9%), and Texas/Florida/Washington where the state rate is 0%.

California and New York have meaningfully different state tables and standard deductions. New York City and Yonkers resident taxes, California SDI, and Pennsylvania/Ohio local taxes are not modelled. Choose the state where you are resident โ€” Texas correctly shows only federal tax.

Federal standard deduction (2026)Single $16,100; MFJ $32,200
Federal single brackets (2026)10%: $0 to $12,400; 12%: $12,400 to $50,400; 22%: $50,400 to $105,700; 24%: $105,700 to $201,775; 32%: $201,775 to $256,225; 35%: $256,225 to $640,600; 37%: $640,600 to above
California state (FTB 2026 schedule)1%: $0 to $11,456; 2%: $11,456 to $27,157; 4%: $27,157 to $42,861; 6%: $42,861 to $59,498; 8%: $59,498 to $75,197; 9.3%: $75,197 to $384,109; 10.3%: $384,109 to $460,927; 11.3%: $460,927 to $768,213; 12.3%: $768,213 to above; SD single $5,900 MFJ $11,800
New York State (NY Tax Dept 2026 schedule)3.9%: $0 to $8,500; 4.4%: $8,500 to $11,700; 5.15%: $11,700 to $13,900; 5.4%: $13,900 to $80,650; 5.9%: $80,650 to $215,400; 6.85%: $215,400 to $1,077,550; 9.65%: $1,077,550 to $5,000,000; 10.3%: $5,000,000 to $25,000,000; 10.9%: $25,000,000 to above; NY SD $8,000 single / $16,050 MFJ (NY's own; MFJ uses NY's married-filing-jointly table)

Worked example (illustrative figures only)

Inputs:
Single ยท $90,000 income ยท standard deduction ยท state CA vs NY vs TX
Estimate:
Federal $10,970 in all three; CA state $4,139 โ†’ total $15,109 net $74,891; NY state $4,271 โ†’ total $15,241 net $74,759; TX state $0 โ†’ total $10,970 net $79,030
What it means:
The same federal tax produces different combined totals because CA and NY state brackets are progressive and peak at 12.3% and 10.9% respectively. Texas has no state income tax, so the federal figure is the total. Each state uses its own standard deduction (California $5,900, New York $8,000 for a single filer). The annual estimate uses FTB published 2026 indexing and NY 2026 IT-2105-I schedules. It is before credits and includes CA behavioral-health surtax and NY benefit recapture.
What is excluded:
NYC resident tax (โ‰ˆ 3โ€“4%) and Yonkers surcharges, CA SDI, and local taxes are not modelled; the NY figure is New York State only. State credits and itemized state deductions are not modelled.

Assumptions

  • Federal tax uses IRS 2026 standard deduction ($16,100 single / $32,200 MFJ) and marginal brackets per filing status (single 10%: $0 to $12,400; 12%: $12,400 to $50,400; 22%: $50,400 to $105,700; 24%: $105,700 to $201,775; 32%: $201,775 to $256,225; 35%: $256,225 to $640,600; 37%: $640,600 to above).
  • CA state tax uses the FTB 2026 schedule (1%: $0 to $11,456; 2%: $11,456 to $27,157; 4%: $27,157 to $42,861; 6%: $42,861 to $59,498; 8%: $59,498 to $75,197; 9.3%: $75,197 to $384,109; 10.3%: $384,109 to $460,927; 11.3%: $460,927 to $768,213; 12.3%: $768,213 to above) with SD $5,900 single / $11,800 MFJ and its own married-filing-jointly schedule (plus 1% above $1,000,000); NY uses the NY Tax Dept 2026 schedule (3.9%: $0 to $8,500; 4.4%: $8,500 to $11,700; 5.15%: $11,700 to $13,900; 5.4%: $13,900 to $80,650; 5.9%: $80,650 to $215,400; 6.85%: $215,400 to $1,077,550; 9.65%: $1,077,550 to $5,000,000; 10.3%: $5,000,000 to $25,000,000; 10.9%: $25,000,000 to above) with NY's own SD ($8,000 single / $16,050 MFJ) and its own MFJ schedule. State AGI is gross income plus the adjustment entered. NY includes its benefit-recapture worksheets; CA adds behavioral-health surtax. This is before credits, not a 540-ES payment calculation.
  • Filing status 0 = Single, 1 = Married Filing Jointly in this calculator; MFS and HoH are approximated as Single for state purposes in the current model.
  • Texas, Florida and Washington are modeled as 0% state tax โ€” correct, they have no individual income tax for 2026.

Not included

  • New York City resident tax, Yonkers resident/nonresident surcharges, and any other city/county/school-district taxes are not modelled โ€” the NY figure is state only.
  • California State Disability Insurance (CA SDI) payroll deduction is not modelled.
  • MFJ vs Single is the only state filing-status distinction fully modeled; MFS and HoH map to Single for state tax in this build, and state credits/exemptions beyond the standard deduction are not modelled.
  • Local taxes generally โ€” especially NYC, Yonkers, and Pennsylvania local earned-income taxes โ€” are not modelled unless a future state page explicitly adds them.
  • This is an annual liability-style estimate, not per-period withholding via Form W-4 / state withholding tables.

Reading the result

  • A higher state top rate does not tax all income at that rate โ€” California and New York are both marginal, so only the slice above each threshold is taxed at the top rate.
  • For an apples-to-apples move comparison, run the same income through CA vs NY vs TX and keep filing status and deduction choice the same.
  • If you live in New York City or Yonkers, add that local liability on top of the New York State figure shown here โ€” otherwise you will understate take-home reduction.

Questions people ask

The US uses a progressive federal tax system with seven marginal tax rates ranging from 10% to 37%. You only pay each rate on income within that bracket โ€” not on all your income. The standard deduction ($16,100 single / $32,200 married filing jointly for 2026) is subtracted from gross income before brackets are applied.
