Avoid Deadline Disaster
Under the Oklahoma Ad Valorem Tax Code a taxpayer has thirty (30) calendar days from the date of mailing of a notice of increase in value to file an informal appeal with the county assessor. If no notice of increase in value has been issued, a taxpayer can still file an informal appeal by the first Monday in May. The taxpayer has ten (10) working days from the date of the assessor’s informal hearing decision to file a formal appeal with the county board of equalization. A taxpayer has ten (10) calendar days from the board’s final adjournment date to continue the appeal by filing a petition in district court. By statute, boards are to adjourn by May 31st, but they have the authority to extend their sessions so it is critical to confirm each board’s final adjournment date. The lack of consistency in the computation of filing deadlines under Oklahoma law can create confusion, but it is essential that deadlines be met because failure to comply will bar an appeal.
