Petition for Rule Changes
You have the right to petition for the issuance, amendment, or repeal of a rule. This provides you the opportunity to identify problematic rules and to help the Taxation improve rules. Fill out the below form which will be submitted directly to Taxation and will be open for public inspection. Action on the submitted petition is at the discretion of the Taxation, but when we undertake rulemaking on the matter, all related petitions for the issuance, amendment, or repeal of rules will be considered and acted upon in the same proceeding.
