A Notice of Proposed Assessment (NOPA) may be issued if you have an outstanding tax liability with the Department of Revenue. The NOPA includes the delinquent tax account, the filing period, and the amount of tax, interest, and penalty due.
If you disagree with the NOPA, you may request an informal conference within 30 days following the date of the NOPA. If you do not request a conference, the NOPA will become a final assessment on the 31st day after the date of the NOPA. If you timely request a conference, and the conference does not result in an adjustment, the NOPA will become a final assessment on the date of the conference decision. If you timely request a conference, and the conference results in an adjustment, you will receive written determination of the adjusted amount owed, which will be your final assessment.
