Use the free Federal Income Tax Return Calculator 2026 on ToolVexa for a simplified estimate of federal tax, and whether the result is a refund or an amount owed, from income, deductions and tax already withheld.
How to Use
Enter annual income, deductions and federal tax already withheld, then press Calculate.
Formula in Plain Words
Subtract deductions from income to get taxable income. In this simplified model, the first $12,000 of taxable income is taxed at 10% and the rest at 22%. Compare the result with tax withheld: withheld tax above the estimate is a refund, and withheld tax below it is an amount owed.
Worked Example
With income $60,000, deductions $15,000 and tax withheld $9,000, taxable income is $45,000. Estimated tax is $1,200 plus $7,260 = $8,460, so the estimated refund is $540.
FAQs
Is this the official 2026 federal tax calculation?
No. This is a simplified estimate only and is not tax advice; official brackets, deductions and credits can change the result.
What if deductions are larger than income?
Taxable income is then treated as $0 in this calculator, so estimated tax is $0.
Why is there a refund?
A refund in this model means tax withheld was more than the simplified estimated tax.
