You may already have a MyCPA user account if you have used MyCPA for WebFile.
Accessing More than one Account:
You can register once for the MyCPA Secure Portal and establish access for as many vendor (or taxpayer) IDs as needed. It is not necessary to create a User ID for each company account.
Access for More than one User ID:
More than one company representative can establish access to the same vendor or taxpayer account with a MyCPA login. (Vendors will use the RG# provided at the end of registration to set up additional users.) However, we highly recommend that one individual be responsible for updating your vendor profile.
How to Register as a Texas Vendor
Apply for CMBL or HUB
To register for the CMBL to be a state vendor or to apply for HUB certification, just follow these steps and get started.
Please note: The CMBL annual registration fee is $70.00. Registration payment may be submitted online with a credit/debit card or check debit (US addresses only). Or, vendors may mail payments, if preferred.
Step 1: Set up your MyCPA user account
- Create your own unique user ID for the MyCPA Secure Login Portal (requires at least seven characters including numbers and case-sensitive letters).
- Enter your e-mail address.
Step 2: Create your MyCPA user profile
This will include your name, telephone number, password and a security question and answer (minimum 5 characters). Please keep your information current. This will enable the Comptroller’s office to provide you with the best customer service.
Step 3: Begin CMBL and/or HUB application process
You will need the following information to get started:
An Employer Identification Number (EIN) issued by the IRS is REQUIRED for registration.
- To obtain an EIN number, go to the IRS Web site or contact by phone at 800-829-4933. Foreign address vendors (addresses outside the continental USA including the states of Alaska and Hawaii) should contact IRS at 215-516-6999. The Comptroller's office takes a proactive approach in the prevention of identity theft and does not accept social security numbers for registration.
