The following tax forms are typically used when selling a business: Form 8594, Asset Acquisition Statement. Form 4797, Sales of Business Property.
Bottom Line. Ordinary income tax applies to regular earnings like wages, salaries and interest and is taxed at your marginal tax rate, which varies from 10% to 37% depending on your income. Capital gains tax, charged when selling assets for a profit, varies depending on how long you owned an asset.
If you sold property that was your home and you also used it for business, you may need to use Form 4797 to report the sale of the part used for business (or the sale of the entire property if used entirely for business). Gain or loss on the sale of the home may be a capital gain or loss or an ordinary gain or loss.
A penalty may be imposed for failure to file Form 8804 when due (including extensions). The penalty for not filing Form 8804 when due is usually 5% of the unpaid tax for each month or part of a month the return is late, but not more than 25% of the unpaid tax.
