Need Assistance Obtaining or Adding a Tax ID?

Please select the option below that applies to your situation:

Already Have a Tax ID?

If your business is already registered with the tax agency and you need Green Leaf to add the tax ID to your account, please submit a request to our Tax Department and select “Add or Remove Tax Jurisdiction” from the ticket-reason dropdown. Please include documentation from the agency confirming the tax ID and account information.

Need to Obtain a New Tax ID?

If your business is not yet registered, you may register directly with the applicable tax agency using the application links provided on this page.

If you would prefer Green Leaf to complete the tax registration on your behalf, please review our State Tax ID Application Process – Let Green Leaf Apply for You! article for information about the service, applicable fees, and how to submit your request.

Important: New tax IDs should be provided to Green Leaf as soon as possible when processing payroll for employees working or residing in the applicable jurisdiction. If payroll tax liabilities are incurred before the required tax ID and account information are provided, Green Leaf may be unable to make timely payments or file required returns. Any resulting penalties, interest, or other fees will remain the responsibility of the business.
