In Oklahoma, the paperwork is the receipts.

Oklahoma asks homeschool families for no notice, no registration, and no testing — the state's one piece of homeschool paperwork arrives at tax time, and it is made entirely of receipts. Oklahoma homeschool families may claim the Parental Choice Tax Credit — up to $1,000 per student — at tax filing, with receipts attached to Form 591-D (70 O.S. §28-101). The families who find April easy have one thing in common: every qualifying receipt was captured the day of the purchase, not excavated from a shoebox in March.
