Capital Gains Tax Calculator

Start with the transaction rather than a headline tax rate. Gross proceeds are the sale amount before selling costs. Subtract those costs and adjusted basis to calculate economic gain or loss. Basis adjustments can be positive or negative; they must not produce negative adjusted basis. Tax-recognition adjustments, including an entered wash-sale disallowance or usable exclusion, appear separately so the receipt explains why taxable gain differs from economic gain. For ordinary purchased property, the disposal date on the acquisition anniversary remains short-term, and the following day begins long-term treatment. The planner compares civil dates rather than assuming that every holding period needs 366 elapsed days. Gifted, inherited and other special holding rules need a reviewed manual classification. Keep original acquisition evidence and any depreciation or exclusion calculations with your own records. A saved older plan without a disposal date retains its manual classification; the calculator does not invent a sale date from today. Waiting can change tax treatment, but it also leaves price, liquidity and transaction risk unresolved.

Choose the income basis before interpreting the federal chart. After-deduction ordinary income excludes the modeled sales and separately entered qualified dividends. The labeled gross-income mode instead subtracts the selected federal standard deduction once; it assumes that deduction is available, including the relevant married-filing-separately restrictions. Qualified dividends and eligible long-term gains share preferential rate capacity, while short-term gains generally add to ordinary income. The current calculation uses the Schedule D worksheet structure for special up-to-25% and up-to-28% groups and compares its ordinary-tax alternative. It uses continuous statutory brackets rather than the IRS Tax Table’s discrete intervals, so it remains a planning estimate. NIIT needs different facts: modified adjusted gross income and net investment income. These cannot be inferred from taxable income alone. The all-investment bridge starts from entered before-sale values; mixed noninvestment facts require separately entered final values. A zero preferential rate therefore does not establish zero NIIT, zero state tax or zero tax on every part of an asset’s gain.

Net gains and losses within short-term and long-term groups, including their character-specific carryovers, before cross-netting opposite signs. A remaining net loss can support a current ordinary-income deduction subject to the applicable limit; actual carryover also depends on income before that deduction. The receipt separates the current deduction, amount used and each next-year carryover. It does not add a possible tax reduction to sale cash as though a refund were certain. The harvesting comparison adds an entered eligible loss, disallowed wash amount and trading cost, then recomputes tax. It does not determine whether replacement purchases trigger wash-sale rules or preserve market exposure. Partial realization scales entered proceeds, basis and costs together. Deferred realization uses an actual entered disposal date and supported policy year. A separately confirmed multi-year illustration conserves entered amounts and advances carryovers while holding the selected policy and other income fixed. It is not a future-law forecast. Donation requires an additional deduction already reviewed for itemization, AGI, year and other applicable limits.

For real estate, depreciation generally affects adjusted basis before the recognized gain is classified. Enter ordinary recapture, unrecaptured section 1250 gain and any confirmed usable exclusion in their separate fields; do not add depreciation twice. Personal-use losses and business classifications need their own reviewed treatment. This calculator does not establish home-sale, section 1202, section 1231, installment or like-kind exchange eligibility. The optional legacy state vectors preserve earlier illustrations but have no verified current-law certification. Washington instead has an entered allocation adapter, usable deductions and credits, and the published tiered rate structure. Using its 2025 deduction for a later policy year is an explicit editable assumption. Preserve supporting records outside the calculator. Remember is off by default, and sharing starts with omitted financial values. Including reviewed values or private lot labels requires separate choices. CSV retains unrounded inputs and calculation records; Print prepares a readable receipt through the browser dialog. For related reference material, the 2027 reference page must be read with its own stated policy assumptions rather than treated as a verified forecast.
