1040PC Form An income tax return that is prepared by computer in a three column "answer-sheet" format. It only prints the bottom line number, dollar amount, and, for most entries, a brief description called a "legend page." Investopedia Says: The 1040PC form can cut the usual 11-page tax return down to just a couple pages. However, the IRS quit accepting this form in 2000, preferring the e-file format instead.
