What Form 940 is for
irs.gov says to use Form 940 to report your annual Federal Unemployment Tax Act (FUTA) tax, which together with state unemployment tax systems provides funds for paying unemployment compensation to workers who have lost their jobs. It adds that most employers pay both a federal and a state unemployment tax, only employers pay FUTA tax, and you should not collect or deduct it from employees' wages. Some employers also need Schedule A (Form 940) for states with a credit reduction or multi-state employers; that schedule has its own PDF on irs.gov. RepeatForm does not work out any amount.
