Missouri law allows a taxpayer to appeal a tax assessment by the Missouri Department of Revenue within sixty (60) days from mailing or delivery of the tax assessment, whichever is earlier. Even if Missouri mails the notice of assessment to the wrong address, as long as the address was the last known address that Missouri had for you, that mailing constitutes delivery of the assessment.
