Now that it is January, tax documents from 2020 will be arriving in the mail soon. As a reminder, contributions to 529 Plans generally allow a state income tax benefit. Typically, this is a deduction against state income tax up to a certain amount, but the tax benefit varies among states. Because there are no 529 Plan tax forms for contributions, this tax benefit can easily be overlooked. If you make a contribution to a 529 Plan, make sure you provide your tax preparer with a copy of the December 31, 2020, statement, which should show the amount contributed to the account for 2020.
