Kintsugi Mail is a secure virtual mail service that centralizes all your state and local tax correspondence in one place.
When tax agencies send mail to your business, it’s routed to your Kintsugi Mail address, scanned, and securely shared with your authorized team members through your Virtual Mail Group.
This article covers everything you need to know about setting up, verifying, and managing Kintsugi Mail and your Virtual Mail Group.
I. What Is Kintsugi Mail
Kintsugi Mail acts as your official business mailing address for state and local tax authorities.
Our partner, Stable, receives your physical mail, scans it, and sends it securely to Kintsugi. The scanned documents are then automatically distributed to everyone in your Virtual Mail Group.
This ensures:
No lost or delayed government notices
Faster response times
Secure and compliant recordkeeping for tax correspondence

III. Checklist: Requirements to Set Up Kintsugi Mail

1. Primary ID (Government-issued photo ID)
For U.S.-based clients:
Driver’s license
Passport or passport card
Non-driver’s ID card
U.S. Armed Forces card
U.S. permanent resident or USCIS ID

⚠️ Important:

IV. If You Already Have a Stable Account
If you’re redirected to your existing Stable account while setting up Kintsugi Mail, follow these steps:
Easy Fix Guide:
Log out of your personal Stable account.
Go back to the Kintsugi Dashboard → Configuration tab.
Select Kintsugi Mail.
Click Setup under the Physical Mail Address section.
You’ll be prompted to create a new Stable account that’s linked specifically to your Kintsugi Mail setup.
💡 Why a separate account?
This Kintsugi-linked Stable account is used exclusively for tax-related correspondence. Keeping it separate ensures your personal and business mail stay organized and secure.
V. Understanding and Managing Your Virtual Mail Group
Once Kintsugi Mail setup is complete, our Tax Operations team will help you create your Virtual Mail Group — your business’s shared digital inbox for all scanned tax correspondence.
What Is a Virtual Mail Group
The Virtual Mail Group is a list of email addresses (team members) who automatically receive scanned copies of all your tax mail.
Here’s how it works:
Tax agencies send mail to your official Kintsugi Mail address (powered by Stable).
Mail is scanned and digitized by Stable.
The Kintsugi team reviews and processes the content.
Scanned documents are shared automatically with all members in your Virtual Mail Group.
Think of it as your central hub for tax-related mail — ensuring that everyone responsible for filings, compliance, and tax notices stays informed.
Why It’s Important
If you’re not included in the Virtual Mail Group, you may miss critical tax notices or state updates.
Always ensure that the right team members — especially those responsible for compliance or filings — are added.
Quick Guide on How to Manage Your Virtual Mail Group
Managing your Virtual Mail Group is quick and easy through the Kintsugi platform.
Log in to your Kintsugi account.
