After registration, businesses must collect the combined state and local option rate on taxable sales, list tax on invoices, and remit electronically through GovConnectIowa. Sellers must separately state exempt delivery charges to preserve exemption.

Sales Tax return due dates explained.

Annual filers (under $1,200 per year) file by January 31. Monthly filers (over $1,200 per year) must file by the last day of the month following the reporting month, and seasonal filers follow the same rule.

All returns are filed online unless specifically permitted otherwise. If the due date falls on a weekend or holiday, it moves to the next business day. Iowa’s filing system treats local and state tax on the same combined return.

Iowa does not offer quarterly filing; only annual, monthly, and seasonal frequencies are available.
