Estimate Investment Sale Outcomes — 2025 Federal Capital Gains Rates
Estimates are for federal capital gains tax only. State taxes, NIIT (3.8%), and other factors may apply.
Long-term capital gains (assets held for more than one year) are taxed at preferential rates of 0%, 15%, or 20% depending on your taxable income and filing status.
| Rate | Single | Married Filing Jointly | Head of Household |
|---|---|---|---|
| 0% | Up to $48,350 | Up to $96,700 | Up to $64,750 |
| 15% | $48,351 – $533,400 | $96,701 – $600,050 | $64,751 – $566,700 |
| 20% | Over $533,400 | Over $600,050 | Over $566,700 |
Married Filing Separately uses half of the Married Filing Jointly thresholds.
When you sell an investment (stocks, bonds, real estate, crypto) for more than you paid, the profit is a capital gain. The tax you owe depends on two key factors:
Short-term capital gains are added to your ordinary income and taxed at your marginal income tax rate, which can be as high as 37% for 2025.
Holding investments for at least one year and one day can significantly reduce your tax bill. For example, a taxpayer in the 32% bracket would save 17 percentage points by qualifying for the 15% long-term rate instead.

Studies show that Americans overpay an average of $1,200 per year in taxes simply because they miss deductions and credits they qualify for. The right tax strategy can save you $2,000 to $10,000 annually, depending on your income, filing status, and life situation.
Not adjusting W-4 withholding after marriage, a new child, or a raise — resulting in a surprise tax bill or an oversized refund (which is an interest-free loan to the IRS).
Choosing the standard deduction without comparing to itemized deductions. Homeowners in high-tax states often miss thousands in savings with the new $40,000 SALT cap.
Missing refundable credits like the Earned Income Tax Credit (EITC). About 20% of eligible taxpayers fail to claim EITC, leaving up to $7,830 on the table.
Tax brackets are marginal. A single filer earning $60,000 pays an effective rate of about 14% — not the 22% bracket rate. Here is how it breaks down:
Average federal tax refund for 2025 filing season. Many taxpayers could keep this money year-round by adjusting their W-4 withholding.
of taxpayers take the standard deduction. With the 2026 increase to $16,100 (single) and $32,200 (married), even more will benefit.
of eligible taxpayers fail to claim the Earned Income Tax Credit, leaving up to $7,830 in refundable credits unclaimed each year.
New 2026 SALT deduction cap under OBBBA, up from $10,000. A major benefit for homeowners in high-tax states like CA, NY, and NJ.
