Method
How this calculator works
It estimates taxable income and applies tax brackets or flat-rate assumptions based on the selected mode.
This calculator is useful for rough tax planning before filing or making withholding changes.
Because assumptions matter, try a few values that represent optimistic, typical, and conservative cases.
Tax and business results are estimates. Rules vary by jurisdiction and can change, so verify important decisions with official guidance or a qualified professional.
Example
Worked example
Using the 2023 single-filer brackets as an illustration: on $60,000 of taxable income, the first $11,000 is taxed at 10% ($1,100), the next $33,725 at 12% ($4,047), and the remaining $15,275 at 22% ($3,361) — about $8,508 in total. That is an effective rate of 14.2%, even though the marginal bracket is 22%. The calculator applies the current year's brackets the same way.
FAQ
Common questions
What is the difference between marginal and effective tax rate?
Your marginal rate is the bracket your last dollar falls into; your effective rate is total tax divided by total income — always lower, because earlier dollars were taxed in lower brackets. Being 'in the 22% bracket' does not mean you pay 22% on everything.
Should I take the standard deduction or itemize?
Take whichever is larger. Since the standard deduction roughly doubled in 2018, most US filers take it; itemizing usually only wins with substantial mortgage interest, state taxes at the cap, or large charitable giving.
Why is my refund not the same as my tax?
The refund is just the difference between what was withheld during the year and what you actually owe. A large refund means you over-withheld — an interest-free loan to the government — not that you paid less tax.
What information do I need for the Income Tax Estimator?
You usually need filing status, income, deductions, credits, and tax year assumptions. You can change the inputs and recalculate as many times as needed.
