Iowa Admin. Code r. 701-86.4
A determination made by the department of either the correct amount of the tax due, or the amount of refund for excessive tax paid, shall be final unless the taxpayer, or any other party aggrieved by the determination, appeals to the director for a revision of the department's determination. For notices of assessment issued on or after January 1, 1995, the department will consider a protest to be timely filed if filed no later than 60 days following the date of assessment notice or, if a taxpayer failed to timely appeal a notice of assessment, the taxpayer may make a payment pursuant to rule 701-78. (17A) and file a refund claim within the period provided by law for filing such claims. In the event of an appeal, the provisions of 701-Chapter 7 of the department's rules of practice and procedure before the department of revenue and Iowa Code chapter 17A shall apply.
This rule is intended to implement Iowa Code chapter 17A and section 45094..
