Capital Gains Tax Calculator
Navigating the 2026 US tax code requires precision. Whether you are selling stocks, liquidated crypto assets, or divesting real estate, understanding your tax liability is crucial for effective wealth management.
Understanding Capital Gains Tax in the USA
Capital gains tax is the levy applied to the profit made from the sale of an asset. In the United States, the Internal Revenue Service (IRS) distinguishes between different types of assets and holding periods. For the 2026 tax year, these rates remain a focal point for investors looking to optimize their portfolios.
Your "cost basis" is typically what you paid for the asset, including commissions and fees. Your "capital gain" is the difference between the selling price and that cost basis.
Short-Term vs. Long-Term Gains
The duration you hold an asset significantly impacts your tax bill:
- Short-Term: Assets held for 365 days or less. These are taxed at your ordinary federal income tax rate (up to 37% in 2026).
- Long-Term: Assets held for more than one year. These benefit from preferential rates: 0%, 15%, or 20%, depending on your total taxable income.
The Capital Gains Formula
Tax Liability = (Sale Price - Purchase Price - Expenses) × Applicable Tax RateDon't forget to include transaction fees or "load" costs in your purchase price to reduce your taxable gain. For real estate, improvements made to the property can also be added to your cost basis.
Projected 2026 Long-Term Brackets

Frequently Asked Questions
What is the "Wash Sale" rule?
The IRS prevents taxpayers from claiming a loss on the sale of a security if they purchase a "substantially identical" security within 30 days before or after the sale. This is vital to remember when trying to offset gains with losses at year-end.
Are cryptocurrencies taxed differently?
No, the IRS treats cryptocurrency as property. This means crypto-to-fiat, crypto-to-crypto, and crypto-for-service transactions are all taxable events subject to the same capital gains rules as stocks.
