What this calculator does and doesn't do
- Computes gain/loss and its holding-period classification.
- Optionally estimates your actual 2026 US federal tax owed on the gain, once you enter your filing status and other income.
- The tax estimate is federal only (no state tax) and assumes no other credits or deductions specific to your situation.
- FIFO matching only -- no LIFO, HIFO, or specific-lot identification.
- Doesn't account for wash-sale-style rules, transaction fees, or non-US regimes.
- Nothing you enter leaves your browser -- no server, no account, no tracking.
This is a free estimation tool, not tax advice. Confirm your numbers with a qualified tax professional before filing.
