US federal tax calculator
Wages plus capital gains, tax year 2025 (the return filed in 2026) -- federal tax only, standard deduction only.
An estimate, computed in your browser — nothing you type here is sent anywhere. It applies the ordinary rules and ignores surcharge relief, set-offs and anything specific to your documents. The return we build from your Form 16 does not.
Why a long-term gain can cost less than the rate suggests
Wages and short-term gains (held a year or less) are taxed together as ordinary income, through the same seven brackets from 10% up to 37%.
A long-term gain (held over a year) does not sit beside that income the way it might elsewhere -- it stacks on top of it. Your ordinary income fills the brackets first; the gain is then taxed at 0%, 15% or 20% depending on where, cumulatively, it lands. That is why two people with the same total gain can owe very different amounts: it depends on what else they earned that year.
This tool applies the standard deduction only -- $15,000 single, $30,000 married filing jointly for 2025 -- and assumes no other income, no itemizing, and no state tax. It does not net a loss in one bucket against a gain in the other; enter a net gain in each.
Common questions
Is this the same engine the real return uses?
No -- this runs in your browser in plain JavaScript. The account-side tool computes in exact decimal arithmetic and is what any return is actually built from. The numbers should match closely, but this one is for a quick estimate, not a filing.
What about state tax?
Not included. State income tax rules vary enormously -- some states have none at all -- and are not built here yet.
Can I use this for Married Filing Separately or Head of Household?
Not yet -- only Single and Married Filing Jointly have bracket tables here today.
Want the exact figure, not an estimate?
Attach your Form 16 and we compute the whole return from the real document — every exemption, every deduction, both regimes, and the right ITR form.
