Understanding Your Results

Federal Long-Term Capital Gains Tax

Applies to profit after depreciation recapture. The rate (0%, 15%, or 20%) depends on your total taxable income. Most investors pay 15%.

Depreciation Recapture (Section 1250)

Often the largest tax component for long-held properties. The IRS "recaptures" depreciation deductions at up to 25% when you sell.

Net Investment Income Tax (NIIT)

An additional 3.8% on investment income if your MAGI exceeds $200,000 (single) or $250,000 (married filing jointly). Not indexed for inflation.
