👉 A checkoff is a tax system in which taxpayers pay a fee to have their contributions recognized and credited toward future taxes. This can be done by direct deposit, where a taxpayer's contributions are automatically deposited into their bank account, or through an automated payment system, where the contributions are processed electronically without the need for paper checks. The primary goal of checkoff systems is to reduce the amount of money that taxpayers have to pay in taxes and make it more accessible to those who cannot afford to pay.
