Iowa law requires that this tax exemption certificate be renewed every three years.
For tax collection purposes, we cannot adjust taxes calculated on accounts. If the exemption is not renewed on time and we collect sales tax on your account, you can file a Claim for Refund Form IA843 with the Iowa Department of Revenue to be reimbursed for any sales taxes you paid on your electric bill.
