If you typed "cheapest county in Texas to form an LLC" into Google, you were probably hoping to find a county where the filing fee is cheaper than the rest of the state. Maybe a quiet rural clerk's office in the Panhandle that would save you a few hundred dollars if you mailed your paperwork there instead of Houston.
That is not how Texas works. And honestly, that is a good thing for your wallet. Just not in the way you expected.
Here is the honest answer, then the part most guides skip.
Forming a Texas LLC means filing a Certificate of Formation (Form 205) with the Texas Secretary of State. The fee for that filing is $300, and it is the same whether your registered office is in Harris County, El Paso County, Loving County, or anywhere else in the state. You can verify this directly on the Texas Secretary of State business forms page.
That fee goes to the state, not the county. No county clerk has the authority to charge a different price for the formation itself. If you read a blog that says "file in [small county] to save money on formation," close the tab and back away slowly. Whoever wrote it has not read the Business Organizations Code.
So if the $300 is flat, why does the "cheapest county" question come up at all?
Because the other costs of operating a Texas business do vary by county. And those costs are where people who ask this question are usually feeling real pain.
Once your LLC exists on paper with the Secretary of State, the real-world cost of running it starts to break down by county in three main places:
The most common variance people actually feel is the DBA. So that is where most of this article focuses.
The table below compares the ten most populous Texas counties on their Assumed Name Certificate filing fee at the county clerk. Costs in this table have not been pulled live from each county clerk for today's date. Treat them as a starting point for your own verification, not a quote.
| County | Main City | Assumed Name (DBA) Filing Fee | Notes |
|---|---|---|---|
| Harris | Houston | UNVERIFIED approx $15 to $25 base + per-page | Largest county in TX. Online filing available. |
| Dallas | Dallas | UNVERIFIED approx $15 to $30 range | Separate online DBA portal. |
| Tarrant | Fort Worth | UNVERIFIED approx $20 range | In-person or mail. Check recorder schedule. |
| Bexar | San Antonio | UNVERIFIED approx $15 to $25 range | Clerk publishes full fee schedule online. |
| Travis | Austin | UNVERIFIED approx $24 to $27 range | Often cited as slightly higher than average. Verify. |
| Collin | McKinney / Plano | UNVERIFIED approx $15 to $20 range | Fast-growing suburb county. |
| Denton | Denton | UNVERIFIED approx $15 to $20 range | Similar fee pattern to Collin. |
| Williamson | Georgetown / Round Rock | UNVERIFIED approx $14 to $18 range | Commonly rumored "cheapest" in Central TX. Verify. |
| Hidalgo | Edinburg / McAllen | UNVERIFIED approx $15 range | Lower cost of living, similar clerk fees. |
| El Paso | El Paso | UNVERIFIED approx $16 to $20 range | Border-adjacent operations common here. |
What the table really tells you: the DBA spread across the ten biggest Texas counties is roughly a twenty-dollar range. The cheapest and the most expensive are separated by less than the cost of dinner for two. If you were hoping to save hundreds of dollars by picking the "right" county, the math will disappoint you.
The savings are not in the filing fee. The savings are in picking a county that actually matches where you run your business, so you do not end up paying for duplicative filings, re-registrations, or a venue mismatch later.
Texas does not have a state income tax, but it does have a franchise tax administered by the Texas Comptroller. The franchise tax applies statewide at the same rate regardless of county. As of the most recent legislative changes, many small LLCs fall under a revenue threshold and owe nothing, but the filing obligation still exists for most entities.
No Texas county charges its own franchise or entity-level tax on top of the state's. So the franchise tax side of your annual cost is flat across all 254 counties. That is one less variable to worry about.
Here is the part every "cheapest county" guide skips.
Texas LLCs can be sued, and the county where your registered office sits often matters for where a lawsuit can be filed. Texas venue rules are detailed (Civil Practice and Remedies Code Chapter 15), and they are opinionated. Some counties are considered friendlier to plaintiffs. Some are considered friendlier to business defendants. Litigators on both sides know the map.
In our view, and this is opinion not legal advice, picking a county purely because the DBA fee is eighteen dollars instead of twenty-four dollars is a false economy if that county also happens to be known as a plaintiff-friendly venue for the industry you operate in. You would have saved six bucks up front and inherited a venue you did not choose strategically.
The reverse is also true. A slightly higher filing fee in a county that matches where your customers live, where your warehouse sits, and where your contracts get performed is usually the right call. Venue follows activity. Activity should follow strategy. Strategy should not follow a five-dollar DBA difference.
Three questions, in order:
One more thing. Texas does not require you to live in Texas to form a Texas LLC. If you are out of state, you still need a registered agent with a physical Texas address. That is where most formation services (including ours) focus their value. The agent's address sets where service of process gets delivered, which ties into the venue conversation above.
If you zoom out from the DBA fee question, the real cost savings on a Texas LLC come from three places:
The cheapest county to form an LLC in Texas is the county where you actually do business. Because the formation fee is $300 statewide and the county-level variance is a few dollars on a DBA filing, the true cost driver is not the county. It is whether the filing is clean, the agent is reliable, and the venue matches your activity.
Cost-sensitive is smart. Penny-wise pound-foolish is not. If the choice is between saving six dollars on a DBA in a county you have no connection to, and filing correctly in the county where you live and work, the correct answer is almost always the second one.
The small savings are rarely where you think they are. The big savings are in not having to redo the work.
