Sales tax exemption certificates play an important role in the landscape of tax compliance, enabling certain buyers to purchase goods without paying sales tax. These certificates serve as essential documentation for both sellers and buyers, ensuring that tax-exempt purchases are well documented and compliant with state regulations.
However, with each state maintaining its own rules regarding exemptions and required documentation, properly managing these certificates is a crucial step for all parties involved.
In this blog post, we’ll dive into the essentials of sales tax exemption certificates, why effective management is critical, and provide you with a comprehensive six-step guide to streamline the process. Whether you’re a business owner or a seller, understanding how to properly handle exemption certificates can save you time, reduce risks, and help you stay compliant as you grow your business.
What are sales tax exemption certificates?
An exemption certificate is a document that allows certain sellers to buy items without paying sales tax. There are a few different types of exemption certificates, which we’ll cover next. Exemption certificates are often used by nonprofits, educational institutions, businesses purchasing for resale, and government entities. Each state has their own rules on who qualifies for exemption and the specific type of documentation required.
Why managing exemption certificates is important
Exemption certificate management is important both for the buyer presenting the certificate, and for the businesses accepting the exemption certificate. In either scenario, proper documentation is required, as states require this information when reporting sales tax collected or paid, to validate any tax-exempt purchases.

Six steps to effectively manage sales tax exemption certificates
1. Understand the different types of exemptions
There are a few types of exemption certificates you may come across depending on the industry you are in, and the types of customers you have. Common types include:
- Nonprofit exemptions: For purchases made by tax-exempt organizations.
- Resale certificates: For businesses that buy products with the intent to resell them.
- Manufacturing exemptions: For businesses that utilize equipment and materials in the manufacturing process.
2. Collect certificates at the point of sale
It’s important to collect any exemption certificate at the point of sale to maintain accurate records. Make it a standard practice to request this documentation from exempt customers before finalizing their purchases.
3. Verify certificate validity
If you are presented with an exemption certificate, it’s up to you to ensure the certificate is valid. Accepting an outdated or inaccurate certificate can result in out-of-pocket expenses, or fines. We outline how to verify a certificate in every state here.
4. Store certificates securely
Create a centralized system for storing exemption certificates. Whether you choose a digital format or a physical filing system, ensure that the certificates are easily accessible and organized, so you are prepared when it comes time to report or in the event of an audit.
5. Periodically review and audit certificates
We recommend conducting regular audits of customer exemption certificates to ensure they remain valid. Expired certificates or duplicates can lead to compliance issues. Set a schedule to review all customer exemption certificates and follow up with customers as needed.
6. Implement technology solutions
Consider using sales tax compliance software to assist with the management of exemption certificates, as many platforms include a feature to help with this. For example, TaxJar customers on the Professional plan can upload and store customer ex
emption certificates in their TaxJar account, keeping all their sales tax data in one place. A solution like this can save you time and reduce the risk of errors.
