Purpose of Form
Generally, use Form 6252 to report income from casual sales during this tax year of real or personal property (other than inventory) if you will receive any payments in a tax year after the year of sale.
Do not file Form 6252 for sales that result in a loss, even if you will receive a payment in a tax year after the year of sale. Instead, report the entire sale on Form 4797, Sales of Business Property, or the Schedule D for your tax return, whichever applies.
Do not file Form 6252 to report sales during the tax year of stock or securities traded on an established securities market. Instead, treat all payments as received during this tax year.
Do not file Form 6252 if you elect not to report the sale on the installment method. To elect out, report the full amount of the gain on a timely filed return (including extensions) on Form 4797 or the Schedule D for your tax return, whichever applies. If you filed your original return on time without making the election, you may make the election on an amended return filed no later than 6 months after the due date of your tax return, excluding extensions. Write "Filed pursuant to section 301.9100-2" at the top of the amended return.
