How much federal income tax will you owe?
Federal income tax is based on taxable income and filing status. The Federal income tax calculator estimates your tax, effective rate and bracket for 2026. The Tax bracket calculator shows the tax in each band, so you can see why moving into a higher bracket does not mean all your income is taxed at that rate.
The 2026 standard deduction is $16,100 for single filers and $32,200 for joint filers. Use these estimates when planning a large purchase, changing jobs or deciding how much money to keep available for your tax bill.
Will your withholding cover your tax bill?
The Tax refund calculator compares your estimated 2026 tax with what has been withheld. If the estimate points to a balance due, the W-4 withholding calculator can help you assess whether to adjust line 4(c) so more is withheld from paychecks. If you expect a refund, consider whether you would rather have more money in each paycheck.
For freelance or contract income, the 1099 tax calculator estimates how much to set aside. The Self-employment tax calculator includes W-2 wages that use up the Social Security wage base, which is $184,500 in 2026. Use the Quarterly estimated tax calculator to estimate payments and review safe-harbor rules before sending money to the IRS.
What tax could apply to investments or a home sale?
The Capital gains tax calculator estimates tax on an investment gain. The Home sale gains calculator helps you check whether a home sale may trigger capital gains tax. These estimates can help you plan the timing of a sale or decide how much of the proceeds to reserve. Confirm tax decisions with a qualified professional, especially when your ownership or use of a property is not straightforward.

State rules can use different brackets, deductions and exemptions. The State income tax calculator estimates tax in any state or D.C.; California income tax, New York income tax and New Jersey income tax are available as separate calculators.

Use Sales tax to add tax to a price, or Reverse sales tax to separate tax from a total. Car sales tax estimates tax on a vehicle purchase. For Texas, Texas sales tax uses the 6.25% state rate and accounts for local rates of up to 2%. Check the applicable rate for the purchase location.
