IRS Form 6252 is used by taxpayers who dispose of property and receive one or more payments after the tax year of sale — known as an installment sale. This form helps calculate the portion of the gain you report in each year payments are received.
When to File Form 6252
You must complete Form 6252 if you:
- Sold real or personal property and received at least one payment in a year after the year of sale.
- Elect to use the installment‑method (under IRC §453) instead of reporting all gain in the year of sale.
- Must file for subsequent years of an installment sale even if no principal payment is received.
Key Sections of the Form
- Part I – Gross Profit and Contract Price: Calculate the profit from the transaction, contract price, and selling expenses.
- Part II – Installment Sale Income: Report payments received during the tax year, apply gross profit percentage, and determine taxable income.
- Part III – Related‑Party Installment Sale Income: Applies when you sold to a related party and must account for accelerated recognition or recapture rules.

Filing Tips & Documentation
- File a separate Form 6252 for each installment sale. Attach it to your tax return (Form 1040 or others as applicable).
- Keep contracts, payment schedules, sale basis information, and records of payments received—these support your entries and future filings.
- Even if you receive only interest in a later year (and no principal), you must still file Form 6252 for that year.
- If you elect out of the installment method (e.g., for certain dealers or inventory property), report the full gain in the year of the sale, not via Form 6252.
Correctly completing Form 6252 ensures the gain from installment sales is reported in the correct years and avoids unexpected tax shortfalls or IRS adjustments.
