Commercial and public service announcement for the IRS; the Harlem Globetrotters are playing around in one of the IRS processing centers, but help highlight seven points for citizens when completing their tax return forms: check your math; compute tax correctly from the right tax table; use the peel off label and coded envelope, included in the received tax packet; attach all W-2 forms from all employers; include all schedules that supplement the main tax return form, and sign the return (if a joint return, ensure there are two signatures); male voiceover: “The main point is, if you’re on the ball at tax time, you’ll score on that refund shot much sooner!”; banner above zoom shot of envelope with refund check: “Department of the Treasury: Internal Revenue Service.”
