Where Your Coryell County DBA Actually Gets Filed
If you're starting a lawn business, a craft booth, or any operation as a sole proprietor, general partnership, or family trust, your assumed-name certificate (the 'doing business as' record) goes to the Coryell County Clerk in Gatesville, same as it always has. Estates, nonprofits, and joint ventures file there too.
What changed is the corporate side. A 2019 state law (House Bill 3609) pulled corporations, LLCs, limited partnerships, and similar registered entities out of the county system entirely. Those file their assumed names only with the Texas Secretary of State now, so it's no use standing in line at the Gatesville courthouse for an LLC's DBA.
One thing to keep in mind: a DBA is just a name on the record. It isn't a sales-tax permit, a city or county business license, or a health permit for a food cart. It tells the public who's behind the name. Sort out your business structure first — sole proprietor versus LLC decides which office you're even walking into.
