Capital Gains Tax Calc
2026 US capital gains tax, explained with IRS sources
Estimate 2026 US capital gains tax on stocks, crypto, and property. See federal tax, supported state taxes, 3.8% NIIT, and home-sale exclusions, with each calculation explained step by step and linked to primary sources. Free, private, and no sign-up required.
Hi !
I'm Amiya, founder of Kordal Systems, and I'm introducing "Capital Gains Tax Calc", a free US capital gains tax calculator built around one principle: "a tax estimate should show its work."
The problem I wanted to solve is simple. Most tax calculators give you a final number without explaining how they arrived at it. Some even confuse your total income tax with the additional tax caused by selling an investment.
I wanted to make that distinction clear and verifiable.
**What I've built:**
- Calculate 2026 capital gains tax on stocks, crypto, and property.
- See federal tax, supported state taxes, and the 3.8% net investment income tax.
- Account for relevant primary-home sale exclusions.
- Understand exactly how each calculation works, with citations to IRS rules and other primary sources.
- Explore what-if scenarios to see how different choices affect the estimate.
Everything runs locally in your browser. No account, no financial data uploads, and no subscription.
The calculator is an educational estimator, not personalized tax advice. I have also published its methodology and known limitations so users can independently examine the calculations.
**I'd really value your feedback:** Which tax scenarios should I prioritize next? Are the explanations clear enough for someone without a tax background?
Thanks for checking it out!
