Investment property can be depreciated over time. When you sell, this depreciation is "recaptured" and taxed at 25%. A 1031 exchange defers this tax as well.

Understanding Your Tax Liability

Federal Capital Gains Tax

Long-term capital gains are taxed at 0%, 15%, or 20% depending on your income level. This is calculated on the difference between your sale price and adjusted cost basis.

Depreciation Recapture Tax

All depreciation claimed over the years is "recaptured" and taxed at 25% when you sell. This tax applies even if you didn't claim depreciation on your tax returns.

Net Investment Income Tax (NIIT)

An additional 3.8% tax on investment income for high-income earners. This applies to real estate gains if your modified adjusted gross income exceeds certain thresholds.

State Capital Gains Tax

Most states tax capital gains as ordinary income. Rates vary significantly by state, from 0% in states with no income tax to over 13% in high-tax states like California.
