On and after July 1, 1987, the period for the department's examination and determination of the correct amount of tax is unlimited in the following circumstances:
For agreements entered into on and after July 1, 1992, the applicable period of limitation can be extended by the taxpayer's signing a waiver on a form provided by the department.
EXAMPLE: An employee of the department examines the books and records of the taxpayer for the period of taxpayer's returns filed on April 30, 1973, to April 30, 1977. The examination is completed on February 3, 1978. The notice of assessment must be given on or before April 30, 1978, in order to include the earliest tax return period above. If the notice of assessment is given on February 2, 1979, it is within the one-year period, but it would not be timely for purposes of the periods April 30, 1973, to December 31, 1973, although the subsequent periods beginning January 1, 1974, to April 30, 1977, could be included.
EXAMPLE: An employee of the department examines a taxpayer's books and records located in Davenport for the returns filed on April 30, 1974, to April 30, 1977. The examination is completed on February 2, 1978. However, the taxpayer's books and records for the same period located in Des Moines have not been examined. The one-year limitation period with reference to the Davenport books and records commences on February 2, 1978. However, the one-year period concerning the Des Moines books and records has not commenced.
This rule is intended to implement Iowa Code subsections 422.54(1), 422.54(2), and 422.70(1) as amended by 1999 Iowa Acts, chapter 156.
