(a) Subject to the exceptions to the time limitations in §§404.1287 and 404.1289, a State is not liable for an amount due under an agreement unless the Commissioner makes an assessment for that amount before the later of the following periods ends:

(1) Three years, 3 months, and 15 days after the year in which the wages, upon which the amount is due, were paid; or

(2) Three years after the date the amount became due.

(b) Where the time limitation ends on a weekend, legal holiday or Federal nonworkday, an assessment is considered timely if the Commissioner makes the assessment on the next Federal workday.
