Ohio Credentials for Importing Registration

How to locate the state-issued credentials required for importing your Ohio registration.
Updated yesterday

To import your existing Ohio sales tax registration into Kintsugi, you'll need to provide a few details issued by the Ohio Department of Taxation when you registered your business. Ohio manages its tax accounts through OH|TAX eServices, the state's online portal for filing, paying, and managing business taxes. Once imported, Kintsugi can manage your Ohio sales tax filings through AutoPilot.

Required Credentials

When importing an existing Ohio sales tax registration into Kintsugi, you'll need the following:

  • Registered Business Name

  • FEIN

  • Any of the following for validation:

    • Assessment Number

    • Letter ID

    • Payment Amount

    • Refund Amount

What's My Registered Business Name?

Your Registered Business Name is the official legal business name you provided to the Ohio Department of Taxation when you registered for your sales tax account.


Where to find it

You can find your Registered Business Name in any of the following places:

  • Your OH|TAX eServices account. Log in at myportal.tax.ohio.gov and review your business profile to confirm the name on file.

  • Your Ohio Vendor's License. Your registered business name appears on the Vendor's License issued to you by the Ohio Department of Taxation after your sales tax account was approved.

  • Ohio Department of Taxation correspondence. Any notices, letters, or account-related communications from the Ohio Department of Taxation will reference your registered business name.

What's My FEIN?

Your FEIN (Federal Employer Identification Number) is the 9-digit federal tax ID number assigned to your business by the IRS. Ohio uses this to identify your business entity in OH|TAX eServices.

Where to find it

You can find your FEIN in any of the following places:

  • IRS EIN confirmation letter. When your FEIN was issued, the IRS sent a confirmation letter (CP 575) with your number.

  • Prior federal tax filings. Your FEIN appears on any federal business tax return you've filed.

  • Your Ohio Business Gateway account. Log in at gateway.ohio.gov and review your business profile to confirm the FEIN on file.

For Validation 

What's My Letter ID?

A Letter ID is a unique identifier printed on correspondence sent to you by the Ohio Department of Taxation. It is used to verify your identity and link you to your tax account. It begins with the letter L followed by 10 digits (for example: L0000123456).

Where to find it

You can find your Letter ID in any of the following places:

  • Ohio Department of Taxation notices or letters. Any correspondence mailed to you by the Ohio Department of Taxation will include a Letter ID printed on the document.

Once access is confirmed, Kintsugi can continue with the registration import setup in the app.
