Employer’s Quarterly Report Item 2, County Code, refers only to your mailing address.

In Item 11, use the county code for the county in which you had the greatest number of employees.

Several Texas counties have names identical to cities located in other counties. For instance:

• The city of Houston is in Harris County (not Houston County)
• Tyler is in Smith County (not Tyler County)
• Austin is in Travis County (not Austin County) 

Be sure to use the correct county name and the code number which follows it.
