Texas Employer Tax Information

To sign up with Square Payroll in Texas, you must provide your Texas Workplace Commission Tax Account Number (TWC Tax Account Number) and State Unemployment Insurance Rate (SUI Rate).

Add Your TWC Tax Account Number to Square Payroll

You must have a TWC Tax Account Number to sign up with Square Payroll. This information is required for us to make tax payments and filings on your behalf.

Don’t Have a TWC Tax Account Number?

The best way to get a TWC Tax Account Number is to create an online account with the Texas Workplace Commission (TWC). Once you successfully enroll, you’ll receive your nine-digit TWC Tax Account Number. 

Alternatively, or if you wish to speak with someone while signing up, you can contact the TWC at 512-463-2731 or tax.statussection@twc.state.tx.us.

Can’t Locate Your TWC Tax Account Number?

To locate your TWC Tax Account Number:

  • If you are transitioning to Square Payroll from a different payroll provider (or have filed state payroll tax returns in the past), you can find your TWC Tax Account Number on any previously submitted quarterly tax filing (Form C-3). The TWC Tax Account Number is a nine-digit number in the following format: XX-XXXXXX-X, and the leading two digits start with either 00-21 or 99.

  • Contact the TWC either via phone at 800-832-9394 or 512-463-2699, or via e-mail at tax.statussection@twc.state.tx.us or tax@twc.state.tx.us.

If you need to update the TWC Tax Account Number we have on file for you, you can do so from the Tax Info tab in your online Square Dashboard.

Add Your Texas SUI Rate to Square Payroll

You must provide your SUI Rate to Square Payroll so we can accurately calculate this tax. To locate your SUI Rate: 

  • Locate the yearly notice sent to you from the TWC that lists your SUI Rate for the upcoming year.

  • Contact the TWC either via phone at 512-305-8708 or via e-mail at taxexperience.rating@twc.state.tx.us.

If your SUI Rate needs to be updated, please contact us.
