Before a distributor will sell to you tax-free, Iowa requires you to document that the purchase is for resale. That is the job of the Iowa Sales/Use/Excise Tax Exemption Certificate, and getting one is an early, unavoidable step for any reseller based in the state.
This guide covers the Iowa specifics: which agency issues what, the exact form, what it costs, how long it takes, and how your suppliers will verify it. It is part of our step-by-step wholesale sourcing roadmap.
Certificate: Iowa Sales/Use/Excise Tax Exemption Certificate (31-014). Prerequisite registration: Iowa Sales Tax Permit. Issuing agency: Iowa Department of Revenue.
Yes – out-of-state buyers may list their home-state permit number, and Iowa (an SST member) accepts the SST Certificate of Exemption and the MTC uniform certificate.
Iowa has no general public lookup for certificate numbers, so suppliers rely on the completed form itself being accurate and signed. Expect distributors to keep your certificate on file — supplier profiles in our catalogue note when a resale certificate is required at account opening.
Certificates are valid up to 3 years; permit does not expire
Usually yes — but the supplier must then charge you sales tax, which comes straight out of your margin, and some distributors simply refuse accounts without resale documentation. Getting the certificate first is almost always worth it.
Iowa suggests refreshing certificates every three years to remain valid documentation. Registration for out-of-state sellers can also be done through the SST registration system.
Facts above summarise official Iowa Department of Revenue guidance; requirements change, so confirm current fees and forms at the agency site. Next step in the roadmap: choosing and verifying a supplier.
