How-To Guides: Iowa SaaS VAT

Step: 1 Threshold

Your business must collect sales tax in Iowa if you have either physical or economic nexus in the state.

  • Physical nexus means that your business has a tangible presence or activity in a state to merit paying sales tax.
  • Economic nexus denotes that your business has met a states’ economic threshold for total revenue or the number of transactions.

 

Economic nexus threshold is USD 100,000 in annual Iowa sales. Registration is mandatory once the threshold is exceeded. No transaction-count alternative threshold applies.

Step: 2 Business Registration

Register with the Iowa Department of Revenue through the online GovConnectIowa portal. Non-resident SaaS sellers must obtain an Iowa sales tax permit before collecting tax.

Step: 3 TIN/VAT Number

A Sales Tax Permit Number is issued by the Iowa Department of Revenue upon registration.

Step: 1 Standard Rate

State sales tax rate is 6%, plus possible local option tax up to 1% depending on customer location.

Step: 2 Rate Formula

To calculate your tax amount, use the following formula:

 

Tax Amount=Net Price × Rate%

Step: 3 Reverse Charge (B2B)

Iowa does not use a reverse charge system. If the seller has nexus, the seller must collect sales tax even for B2B transactions unless the buyer provides a valid resale or exemption certificate.

Step: 1 Selling B2C

SaaS and specified digital products are taxable when delivered to an Iowa consumer. Sellers with nexus must charge destination-based tax including local option tax.

Step: 2 Selling B2B

Tax applies unless the buyer provides a valid exemption certificate (e.g., resale or exempt entity). No reverse charge applies; seller remains responsible for collection.

Step: 3 Invoice Requirements

Invoices should contain:

  • Supplier legal name and address;
  • Sales Tax Permit Number;
  • invoice date;
  • unique invoice number;
  • description of SaaS/digital service;
  • taxable amount;
  • tax rate applied;
  • tax amount charged;
  • customer name/address;
  • exemption certificate details if applicable;
  • total invoice amount;
  • currency used.

Step: 1 Filing Interval

Assigned by the Iowa Department of Revenue based on volume: typically monthly, quarterly, or annually.

Step: 2 Filing Deadline

Returns are due on the last day of the month following the reporting period.

Step: 3 Submission

Filed electronically via GovConnectIowa portal; payment through ACH debit/credit or approved electronic payment methods.

Step: 4 Record Keeping

Records must generally be kept for at least 3 years.
