Capital Gains Tax in 2026: What You Need to Know
When you sell an asset—whether it's stocks, crypto, or real estate—for more than you paid for it, the IRS calls that a "Capital Gain." How much tax you pay depends heavily on how long you held the asset.
Short-Term vs. Long-Term Gains
- Short-Term (< 1 Year): Taxed as "Ordinary Income." This is added to your salary and taxed at your top bracket (up to 37%).
- Long-Term (> 1 Year): Taxed at preferential rates: 0%, 15%, or 20%. Most Americans fall into the 15% bucket.
The NIIT Surcharge (High Earners)
If your Modified Adjusted Gross Income (MAGI) exceeds $200,000 (Single) or $250,000 (Married Filing Jointly), you may owe an additional 3.8% Net Investment Income Tax (NIIT) on your gains. Our calculator automatically checks this for you.
State Taxes Matter
Don't forget your state! While Florida and Texas have 0% state capital gains tax, California can take up to 13.3% extra. This calculator includes logic for all 50 states to give you a realistic "Take Home" number.

Frequently Asked Questions
What if I sell my primary home? ↓
If you lived in the home for 2 of the last 5 years, you can exclude up to $250,000 (Single) or $500,000 (Married) of profit from taxes. This is the "Section 121 Exclusion."
How does Tax-Loss Harvesting work? ↓
If you have other investments that are down, you can sell them to "harvest" a loss. This loss can offset your gains dollar-for-dollar, lowering your tax bill.
Is Crypto taxed differently? ↓
No. In the eyes of the IRS, cryptocurrency is property. Trading one coin for another is a taxable event, just like selling a stock.
