When the tax filing country you submit in Worksuite's Tax Information Form is United States, our system will validate both the Name and Tax Identification Number (TIN) -- whether Social Security Number (SSN) for an Individual or Employer Identification Number (EIN) for a Business -- against official IRS records.

What are the best practices for correctly entering my Tax Information?

For SSN, first select Individual and then enter your ID using the standard 9-digit format, including hyphens: XXX-XX-XXXX

For EIN, first select Business and then enter your ID using the standard 9-digit format, including hyphens: XX-XXXXXXX

I am encountering the error "TIN verification failed: the SSN/EIN you entered is not valid"

This error may indicate a discrepancy between IRS records and either your TIN or the name you are entering.

When filing as a Business, please enter the business name exactly as it appears on the IRS registration form you received.

For example, the IRS disallows commas, so while you might intend for your business name to be "ABC, LLC", you'll see on the registration form that the name is "ABC LLC" and should be submitted as such.

The form saved successfully, and then I received an email that the information is invalid.

Most of our validations occur in real-time, however this is dependent on the availability of IRS's validation service, and some validations occur asynchronously. Please resubmit your information accurately.
