When a seller accepts a Mortgage for part of the sale, the tax on the gain is paid as the mortgage Principal is collected. See also Contract Price, Gross Profit Ratio, Imputed Interest.
Example: Collins sells for $100,000 her land that she bought 3 years ago for $40,000. Her gain is $60,000. She receives 10% ($10,000) as a cash Down Payment and a 90% ($90,000) Purchase Money Mortgage. She will report 10% of the gain in the year of sale and the balance as she collects the principal of the purchase money mortgage. To do so, on her tax return she reports the sale as an installment sale. See Table 28.
