Who Needs an Iowa Sales and Use Tax Permit

A retailer making taxable sales of goods, specified digital products or taxable services in Iowa, or for use in Iowa, must have an Iowa sales and use tax permit before doing business. A business that makes no taxable retail sales does not need one.

How to Apply

Iowa requires your registration to be displayed at the place of business.

What It Costs

Iowa charges no fee for the sales and use tax permit.

Iowa may require security, such as a bond or deposit. A new applicant may be asked to post a bond or security if the Department finds it could not pay the tax on time, it had tax problems under an earlier permit, or it is controlled by the owners of a business whose permit was revoked. The usual amount is five months of tax for a monthly filer or one year of tax for an annual filer, and never less than $100.

Does It Expire?

The sales and use tax permit does not expire. The permit stays valid until the Department revokes it or you cancel it.

More Than One Location

A business needs a separate sales and use tax permit for each place of business in Iowa. A permit moves with you to a new location in the same county if ownership stays the same. A seller making sales from outside Iowa, or without a place of business in Iowa, gets one permit however many locations it sells from.

Local Sales Taxes in Iowa

Worth Knowing in Iowa

This guide is general information, not legal or tax advice, and reading it does not create an attorney-client relationship. It reports what each state's law and tax agency say about the registration a business holds before it makes taxable sales, with the sources this page cites. It cannot tell you whether your own business must register: that turns on what you sell, where you sell it from, and how much you sell into the state, and fees, security rules and thresholds change between our reviews. Confirm your own position with the tax agency named on this page before you start selling.
