2026 federal income tax estimate
A federal tax calculator that shows its work.
Enter the facts you know—starting with W-2 wages and federal withholding—and review a preliminary 2026 federal result. SargoTax AI separates income, deductions, credits, taxes, payments, and supported Schedule 1-A tips or overtime adjustments so the result is easier to understand.
What the federal estimate includes
The supported path starts with filing status, W-2 wages, other ordinary income, adjustments, federal withholding, and estimated payments. Optional modules can add supported self-employment, household credits, investments, deductions, rental, multi-state, foreign-tax facts, and Schedule 1-A qualified tips or overtime when they apply.
The result is not one unexplained refund number. SargoTax AI shows adjusted gross income, the deduction used, taxable income, income tax, supported credits, self-employment tax when applicable, and payments.
Why a refund can change
A refund is generally the difference between supported tax and entered payments or refundable credits. It is not a bonus generated by the calculator. Adding income, correcting withholding, or changing a credit can move the result in either direction.
Unsupported or incomplete facts remain flagged instead of being silently treated as zero. That is especially important for tax situations that require a separate form, allocation, or professional judgment.
Plain-language answers
Common questions
Is this the official IRS tax calculator?
No. SargoTax AI is an independent educational estimator and is not affiliated with or endorsed by the IRS.
Does the calculator file my tax return?
No. It creates a preliminary estimate; it does not prepare, sign, transmit, or file a return.
Can I change the numbers?
Yes. You can revise the entered facts and calculate again to see how the supported result changes.
