Florida: How do I locate my Business Partner Number?

Your Business Partner Number is the number used to login at the bottom half of this Florida e-file screen:

Florida Business Partner Number

If you're not sure where to locate this detail for your account, there are a couple of places to check:

1) It is listed in smaller print on the back of your Florida sales tax permit.

  • The full Business Partner Number will be 14 digits, but the state requires only the first 13 digits to login to the e-file website.
  • AutoFile enrollment also requires only the first 13 digits.

2) The state can also do a lookup of this number of you give them a call at 850-488-6800.
Press 1 for English, then 2 for general information on taxes, then 2 for any other taxes. (You can also try pressing 0 after pressing 1 for English. This 0 is a hidden option that doesn’t always work!)
