Understand Certificates, Affidavits, and Requests in CertCapture

This article applies to:Avalara CertCapture

In CertCapture's exemption matrix, three kinds of documents can be mapped to exposure zones and exempt reasons - certificates, affidavits, and requests. All three document types can be saved to CertCapture via upload, fax, online form submission tool, API, or retail app. Below are descriptions for each type and explanations of when to use them in your compliance process.

Use document types in CertCapture


In CertCapture, certificates are defined as fillable forms that collect required buyer and seller information and create an exemption certificate that is active for the period defined by the exemption matrix. They're saved and associated with your customer's account.


Affidavits are defined as fillable forms that enable a buyer to agree to the requirements of exemption, and may define additional forms/documents that they also need to submit. They're active for a period not defined by the exemption matrix, but by you in your CertCapture settings. They're saved and associated with your customer's account.

In other words, affidavits act like temporary certificates. If a customer would like to transact with your business but they don't have a document present, you may issue an affidavit as a “temporary exemption” for a designated grace period.


Requests are defined as a set of instructions that provides a buyer with all the information they need to submit the state or federal supplied document necessary for exemption. They can be used as a cover sheet to help auto-associate the submitted form with the Buyer account.

In other words, requests are documents with instructions on submitting additional documentation. They can be provided to the customer at the point of sale, but don't grant immediate tax exempt status.
