36 M.R.S. § 3213 — Refunds of taxes erroneously or illegally collected

If the State Tax Assessor determines that a tax or penalty imposed by this chapter has been erroneously or illegally collected from a user, that user is entitled to a refund of the amount that was erroneously or illegally collected. The refund must be paid to that user from the Highway Fund.
A refund may not be made under this section unless a written claim stating the grounds upon which the refund is claimed in a form prescribed by the assessor is filed with the assessor within 3 years from the date of the payment of the amount that was erroneously or illegally collected.
