Community Enhancement / Entrepreneurship / Small Business Guide / Getting Started / Name, Registrations, and Tax ID

Another important step in getting a business ready for opening day involves securing a business name, registering the business with the appropriate authorities, and getting tax identification numbers from the federal, state, and/or local government. It is important to take care of these issues early in the process, as this information may be needed to secure permits, licenses, and potentially financing.

Many of these services are provided by the Texas Secretary of State through its online service, SOS Direct.

Naming Your Business

Naming your business requires more than creativity and good spelling skills. After determining the name you would like to use for your business, do a preliminary check of the name’s availability through the secretary of state’s commercial database. This can be done in a matter of minutes. Preliminary checks may be made online.

Corporations and LLCs must secure their names through the secretary of state’s office. This can be done at the time of incorporation or a name may be reserved for sixty days if you are not ready to incorporate. Reserving a name costs $40.

Do not rely on a preliminary check of a name’s availability. Formally reserve the name and wait for confirmation from the secretary of state’s office before obtaining stationery, business cards, phone listings, bank accounts, etc. For the secretary of state’s name filings FAQs, go here.

Registering Your Business

Where you register your business depends on your business structure. Corporations, LLCs, and LLPs need to register at the secretary of state’s office. Forms for registering a business can be found on the secretary of state’s website. Corporations will need to file articles of incorporation at the time of registration. Professional assistance from an attorney is recommended for this process.

Companies that are not incorporated, such as sole proprietorships, register at the county clerk’s office in the county where the entity is doing business. To register your business with the county clerk, you will need to submit an assumed name certificate. You may access the form and the corresponding instructions here.

The completed form will need to be notarized prior to filing it in person at the county clerk’s office. The cost of filing a form in this manner is $18, with an incremental increase for additional owner names. If you wish to complete the form in person at the county clerk’s office, one of the deputies can acknowledge your signature. Plan to bring a state issued picture ID. The cost for filing the form in this manner is $23.

The Williamson County Clerk’s office is located in the Williamson County Justice Center at 405 Martin Luther King St., Georgetown, TX 78626-4901. You may also reach the county clerk’s office at 512.943.1100.
