701—104.7 (423A) Application of payments. Since a combined hotel and motel tax and quarterly state sales tax return is utilized by the department, all payments received with the return will be applied to satisfy state sales tax and hotel and motel tax liabilities, which include penalty and interest. Application of partial payments received with the tax return and any subsequent partial payment received for that tax period will be applied based on a ratio formula, unless properly designated by the taxpayer as provided in Iowa Code section 421.60(2)“d.” The denominator in the ratio shall be the total of the hotel and motel tax due and the state sales tax due less any monthly sales tax deposits. The numerators in the ratio formula shall be the amounts of hotel and motel tax due and the net state sales tax due.
Example:  XYZ hotel owes a total of $1,000 in net state sales tax and hotel and motel tax for the quarter. Of the $1,000 owed, $600 is for hotel and motel tax and $400 is for state sales tax. XYZ files its quarterly sales tax return accompanied by a $500 partial payment. The $500 partial payment would be applied based on the following computation:

 	600	×	500	=	$300	Hotel and motel tax	 	
 	1000						 	
 	400	×	500	=	$200	State sales tax	 	
 	1000						 	
All revenues received under Iowa Code chapter 423A are to be credited to the “local transient guest tax fund.” Revenues include all interest and penalties applicable to any hotel and motel tax report or remittance, whether resulting from delinquencies or audits. All revenues received or moneys refunded 180 days after the date on which a city or county terminates its local hotel and motel tax shall be deposited in or withdrawn from the state general fund. The 180-day limitation applies to actual receipts or disbursements and not to accrued but unpaid tax liabilities or potential refunds.
This rule is intended to implement 2005 Iowa Code Supplement section 423A.7.
