Enter your purchase price, sale price, and holding period to see your exact capital gains tax — including federal rate, state rate, NIIT surcharge, and true net proceeds.
Holding an asset for more than one year converts ordinary income rates (up to 37%) to long-term capital gains rates (0%, 15%, or 20%). For most taxpayers in the 22–24% federal bracket, long-term gains are taxed at only 15% — a 7–9% tax rate advantage that makes the holding period decision enormously valuable.
