Example: Jones contracts to sell stock in a controlled foreign corporation for $5,000 to be paid in 10 equal payments of $500 each, plus a sufficient amount of interest so that section 483 does not apply. He properly elects under section 453 to report under the installment method gain of $1,000 which is includible in gross income under section 1248 as a dividend and gain of $500 which is a long-term capital gain. Accordingly, $150 of each of the first 6 installment payments and $100 of the seventh installment payment are included in gross income under section 1248 as a dividend, and $50 of the seventh installment payment and $150 of each of the last 3 installment payments are long-term capital gain.
