This guide walks you through the steps for adding and managing customer tax exemptions in Kintsugi. Keeping these records up-to-date helps ensure accurate tax calculations and smooth compliance with state requirements.
Before adding exemptions, gather the necessary information. A well-organized spreadsheet will make the process faster and easier.
Make sure your spreadsheet includes:
Customer name
Contact email
Exemption type
Exemption expiration date (if applicable)
State of operation
FEIN and Sales Tax ID number (if available)
Exemption certificate (if available)
If you don’t yet have a certificate, we recommend requesting one from your customer. This document is important for audit readiness.
Visit Kintsugi App and enter your credentials.
There are two ways to add a tax exemption certificate for a customer via the Customers and Exemptions tabs. We will show you both approaches here.
Navigate to the Customers tab.
Use the search bar to find a customer by email or name.
Click on the customer to open their profile
Click the Add button to add an exemption certificate for the customer.
A pop-up form will appear with the details needed to add an exemption certificate.
Navigate to the Exemptions tab.
Click the Import button.
A pop-up form will appear with the details needed to add an exemption certificate.
The forms above are similar, except that when accessed via the Exemptions tab, you must fill in the Customer field.
Search for the Customer to find them if you access the form via Exemptions.
Fill the rest of the form (Refer to your Customer Exemption Spreadsheet).
a. State: Select the state from the dropdown.
b. Start Date: Use 01/01/2024 as a default if not specified, or enter the actual start date if available.
c. End Date: Enter the expiration date from the spreadsheet. If no specific expiration date is provided, set it at least five years in the future. For exemptions that are in perpetuity, the start/end date may not be necessary.
d. FEIN and Sales Tax ID: Customer exemption identifiers (FEIN & Sales Tax ID) are optional if no certificate is uploaded. They can be used as an alternative proof of exemption. Enter "N/A" if no certificate or identifiers exist.
e. Exemption Certificate: Upload if available. If not, ensure you have valid documentation or proof of exempt status. You can also verify nonprofit exemptions through the IRS Exempt Organization Search
Click Save to apply the exemption.
4. A confirmation message will appear on the screen.

5. Verify the customer exemption in the Customer Details page. It should appear under the Exemptions section.
Repeat the steps for each customer in your spreadsheet.
To update or remove exemptions:
Go to the customer’s profile.
Click the three dots next to the exemption.
Choose Edit, Download, or Deactivate as needed.
Use Actual Dates When Available: Especially important if you're using Kintsugi's Bi-directional Integration, which automatically checks for valid exemption periods.
Keep Certificates On File: In the event of a state audit, these documents are essential. Missing certificates can put your business at risk.
Customer Responsibility: Ultimately, customers are responsible for proving their exempt status. Make sure they provide the required information to avoid potential tax liabilities. Kintsugi recommends keeping these records on file to streamline compliance processes.
We’re working on a feature that will allow you to mark exemptions as never expiring. Until then, if your customer has a long-term or permanent exemption, set the expiration date far into the future (5+ years).
