2026 Real Estate Capital Gains Calculator Tax Year 2026
Calculate your federal capital gains tax on the sale of real estate in 2026. Supports primary residence exclusion (Section 121), investment property depreciation recapture, 1031 like-kind exchanges, and the Net Investment Income Tax (NIIT).
2026 Real Estate Capital Gains Overview
When you sell real estate for a profit, the gain may be subject to federal capital gains tax. The tax rate depends on how long you held the property, your taxable income, and whether the property was your primary residence or an investment property.
2026 Long-Term Capital Gains Tax Rates
For assets held more than one year, long-term capital gains are taxed at preferential rates: 0%, 15%, or 20% based on your taxable income and filing status.
| Filing Status | 0% Rate | 15% Rate | 20% Rate |
|---|---|---|---|
| Single | $0 – $49,450 | $49,451 – $545,500 | $545,501+ |
| Married Filing Jointly | $0 – $98,900 | $98,901 – $613,700 | $613,701+ |

Section 121 Primary Residence Exclusion
Under IRC Section 121, you can exclude up to $250,000 of capital gain (or $500,000 for married filing jointly) from the sale of your primary residence. To qualify, you must have owned and lived in the home as your primary residence for at least two of the five years before the sale. These amounts are statutory and not adjusted for inflation.
Depreciation Recapture on Investment Property
When you sell an investment or rental property, any depreciation you claimed (or were allowed to claim) during ownership is recaptured as taxable gain. For residential real estate (Section 1250), depreciation recapture is taxed at a maximum federal rate of 25% as "unrecaptured Section 1250 gain." Gain above the depreciation amount is taxed at the regular long-term capital gains rates.
1031 Like-Kind Exchanges
A 1031 exchange allows real estate investors to defer capital gains tax by reinvesting the proceeds from the sale of investment property into a like-kind replacement property. To qualify, you must identify replacement property within 45 days and close within 180 days. The deferred gain is not taxed until the replacement property is eventually sold (without another exchange).
Net Investment Income Tax (NIIT)
The Net Investment Income Tax is a 3.8% surtax on investment income (including capital gains) for high-income taxpayers. The thresholds are:
- Single / Head of Household: $200,000
- Married Filing Jointly: $250,000
- Married Filing Separately: $125,000
These thresholds are not indexed for inflation and have remained unchanged since 2013.
