701—108.9(437B) Taxpayers required to keep records.
	108.9(1) Records required by taxpayers taxed under Iowa Code chapter 437B. The records required in this rule must be made available for examination upon request by the director or the director’s authorized representative. The records must include all of those which would support the entries required to be made on the tax return. These records include but are not limited to:
	a. 	Records associated with the total number of gallons of water carried through the taxpayer’s distribution system during the tax year and during each of the immediately preceding five calendar years. For calendar years prior to tax year 2013, the total number of gallons of water carried through the taxpayer’s distribution system is calculated as though Iowa Code chapter 437B was in effect for such calendar year.
	b. 	Records associated with the total amount of nonrevenue water, as that term is defined in Iowa Code section 437B.2(9), carried through the taxpayer’s distribution system during the tax year and during each of the immediately preceding five calendar years. For calendar years prior to tax year 2013, the total number of gallons of nonrevenue water carried through the taxpayer’s distribution system is calculated as though Iowa Code chapter 437B was in effect for such calendar year.
	c. 	Records associated with the total taxable gallons of water delivered by the taxpayer to consumers, as that term is defined in Iowa Code section 437B.2(2), within the service area during the tax year and during each of the immediately preceding five calendar years. For calendar years prior to tax year 2013, the total taxable gallons delivered by the taxpayer to consumers by the water utility is the difference between the gallons of water calculated in paragraphs 108.9(1)“a” and “b.”
	d. 	For tax years 2013, 2014, and 2015, records associated with property tax amounts due and payable as the result of assessment years 2010 and 2011.
	e. 	Records associated with the taxpayer’s calculation of the tentative replacement taxes due for the tax year and required to be shown on the tax return.
	f. 	Records associated with increases or decreases in the tentative replacement tax required to be shown to be due where the replacement delivery tax rates are subject to recalculation under the provisions of Iowa Code section 437B.4(5).
	g. 	All work papers associated with any of the records described in this subrule.
	h. 	Records pertaining to any additions or deletions of property described as exempt from local property tax in Iowa Code section 437B.12.
	i. 	Records associated with allocation of property described in paragraph 108.9(1)“h” above among local taxing districts.
	108.9(2) The records required to be maintained by this rule shall be maintained by taxpayers for a period of ten years following the later of the original due date for the filing of a tax return in which the replacement taxes are reported or the date on which such return is filed. Upon application to the director and for good cause shown, the director may shorten the period for which any records should be maintained by a taxpayer.
