Capital Gains Tax Calculator

A progressive tax system divides income into slices and assigns each slice its own rate. In the US federal system the lowest slice is taxed at 10%, the next at 12%, then 22%, 24%, 32%, 35%, and a top slice at 37%. Crucially, moving into a higher bracket only raises the rate on the income inside that new slice — not on everything you earned.

Concrete example: a single filer earning $120,000 in 2024. After the standard deduction of $14,600, taxable income is about $105,400. The 12% bracket runs up to roughly $47,150 of taxable income and the 22% bracket begins there, so most of this filer's income is taxed at 10% and 12%, and only the slice above roughly $47,150 hits 22%. The marginal rate — the rate on the next dollar earned — is 22%. The effective rate — total tax divided by total income — lands closer to 15–17%. Two vocabulary words, two very different numbers, and confusing them is the single most common tax misunderstanding.

This is why "I don't want a raise that pushes me into a higher bracket" is always wrong arithmetic: earning one extra dollar can never reduce your after-tax income, because that dollar is only ever taxed at your marginal rate.

A deduction reduces the income your tax is computed on, so its value depends on your bracket: a $1,000 deduction saves $220 at a 22% marginal rate but $120 at 12%. A credit reduces tax directly: a $1,000 credit removes $1,000 from the bill regardless of bracket. Refundable credits go further — they can push the balance below zero and send money back even if no tax was owed. The standard deduction (about $14,600 single, $29,200 married filing jointly for 2024) sits alongside itemized deductions such as mortgage interest, state and local taxes within a cap, and charitable contributions; most filers take whichever is larger.

Freelancers and gig workers carry a second layer. Self-employment tax covers Social Security and Medicare at 15.3% of net self-employment earnings (12.4% Social Security up to the annual wage base — $168,600 for 2024 — plus 2.9% Medicare, with an additional Medicare surtax at high incomes). Employees never see this as a line item because their employer quietly pays an equal share; the self-employed pay both halves. The same income can therefore be taxed twice over: once by income tax and once by self-employment tax.

Because there is no employer withholding, the tax calendar shifts: quarterly estimated payments due in April, June, September, and January keep pace with the liability. Underpaying across the year can trigger penalties even if you settle up in full the following April — the system expects the money spread through the year, not delivered as a lump sum.

Estate and gift tax rules govern how wealth crosses to the next generation. For 2024, the federal estate tax exemption is roughly $13.61 million per person (about $27.22 million for a married couple), and the annual gift exclusion lets each donor give $18,000 per recipient per year with no paperwork. Gifts above the annual exclusion count against the lifetime exemption; only estates above the lifetime exemption face federal estate tax, which is why most estates file no federal estate tax return at all. State rules diverge sharply — several states run their own estate or inheritance taxes with far lower thresholds — and scheduled changes to the federal exemption make the current figures time-bound rather than permanent.

Transfers within families also run through vehicles with their own arithmetic: credit shelter trusts divide a couple's exemption across two estates; grantor retained annuity trusts (GRATs) freeze an asset's growth outside the estate; charitable remainder trusts pay an income stream to beneficiaries with the remainder going to charity, and generate a partial deduction today; qualified personal residence trusts (QPRTs) transfer a home at a discounted value. Each has an IRS-backed calculation — present value, annuity term, remainder factor — that these calculators implement.

There is a plain-English thread through all of it: estate math is present-value math under a deadline. The exemption level, the annual exclusion, the exemption scheduled to change, the age at which a transfer starts — every input is a number with a date on it, and the result is an estimate that must be checked against the rules in force when the transfer actually happens.
