Under the installment method, each payment of principal is part return of your basis and part gain. The share that is gain, the gross profit percentage, is your gross profit divided by the contract price. Each year you multiply the principal you received by that percentage and report the result on Form 6252.
Real sales are messier: selling costs, recapture and liabilities the buyer assumes all change the math. The example only shows the shape of it.
In an asset sale, the price has to be divided among the assets sold, using seven classes that run from cash, through inventory and equipment, to goodwill. Both the buyer and the seller must file Form 8594 with their returns for the year of the sale. The allocation decides how much of your gain is recapture, how much is capital gain, and how much can be deferred, so it’s worth agreeing on it in the purchase agreement rather than leaving each side to pick its own numbers.
If you use the cash method, interest on the note is ordinary income in the year you receive it. If the note doesn’t carry enough stated interest, the IRS can treat part of the price as interest (unstated interest or original issue discount), and you may have to report some interest even in a year with no payment. For sales, the minimum test rate is generally the lowest applicable federal rate for a note of your term (short, mid or long) in the three-month period ending with the month of the binding contract.
The buyer generally can deduct the interest, subject to limits, and a business that pays $600 or more of interest in the course of its trade to a payee that isn’t a corporation generally files Form 1099-INT. The cleanest result is one interest figure that both sides use.
PaperItUp tracks every payment against your note, splits interest and principal, and gives you and your CPA the year’s figures, with the buyer seeing the same numbers. We never hold your money.
Generally yes: you use Form 6252 for the year of the sale and for each later year in which you receive a payment on the note, so the gain is reported as you’re paid.
No. Interest is ordinary income in the year you receive it (and sometimes in years you don’t, if the interest is unstated or original issue discount). The gain on the sale is reported under the installment method and may qualify for capital gain rates, depending on the assets sold.
Two rules apply to related buyers. If the related buyer resells within two years, you can be taxed on that second sale as if you’d been paid. And sales of depreciable property to certain related persons generally can’t use the installment method. Your CPA should review any related-party sale.
Yes. You can elect out of the installment method by reporting the whole gain on Form 8949, Form 4797, or both instead of Form 6252, by the due date (including extensions) of the return for the year of sale. Once made, the election can be undone only with IRS approval, so talk to your CPA first.
