So you’ve formed your Texas LLC and now you’re getting mail from the Texas Comptroller with cryptic numbers like “FQ123456” and wondering what the heck is going on. Welcome to the wonderful world of Texas WebFile numbers—one of those bureaucratic peculiarities that makes perfect sense to government officials and confuses everyone else.
Here’s the deal: Texas issues three different types of WebFile numbers to your LLC, and each one serves a specific purpose. Mix them up, and you’ll be calling the Comptroller’s office like I did when I first started helping Texas entrepreneurs (spoiler: they weren’t thrilled).
After navigating this system with hundreds of clients over the years, I can tell you it’s actually not that complicated once you understand the logic. Let me break it down in plain English.
What Are Texas WebFile Numbers?
WebFile numbers are basically Texas’s way of tracking your LLC for different types of filings and payments. Think of them as specialized ID numbers that tell the Comptroller’s computer system exactly what type of business you’re doing with them.
WebFile itself is just the name of Texas’s online filing system—nothing fancy, just government branding for their website portal.
Your Texas LLC will get up to three different WebFile numbers:
- FQ Number: Your starter number for initial franchise tax questionnaire
- XT Number: For annual reports and franchise tax returns
- RT Number: For sales tax and other business taxes
Most LLCs will get an FQ and XT number automatically. You only get an RT number if you register for sales tax or other specific business taxes.
Let me walk you through each one and when you’ll actually use them.
The FQ Number: Your LLC’s First Texas ID
The FQ number is your LLC’s introduction to the Texas tax system. Every single Texas LLC gets one, whether you want it or not.
How You Get Your FQ Number
About 2-3 weeks after the Texas Secretary of State approves your LLC formation, the Comptroller’s office will mail you a “Welcome Letter.” This isn’t just Texas being polite—it’s an official document you need to keep.
The FQ number appears at the top of this Welcome Letter, and it looks something like “FQ12345678.”
Jake’s reality check: I’ve had clients who threw away this letter thinking it was junk mail. Don’t be that person. The Comptroller’s office doesn’t send junk mail—everything they send matters.
What You Do With Your FQ Number
Your FQ number has exactly one job: completing your initial Franchise Tax Questionnaire.
This questionnaire is mandatory for all Texas LLCs. The state wants to know basic information about your business to determine if you’ll owe franchise tax. Most LLCs won’t owe any franchise tax (more on that below), but you still have to complete the questionnaire.
Important timing: You need to complete this questionnaire reasonably soon after receiving your Welcome Letter. Texas doesn’t give you a specific deadline, but don’t let it sit for months.
Lost Your Welcome Letter? Here’s How to Get Your FQ Number
If you can’t find your Welcome Letter (happens to the best of us), call the Texas Comptroller at 512-463-4402. Here’s the exact phone menu sequence that actually works:
- Press option 5
- Press the star (*) key
- Press option 5 again
- Wait through the recorded message
- You’ll get transferred to a real person
Have your LLC’s exact legal name and formation date ready—they’ll ask for it.
The XT Number: For Annual Reports and Franchise Tax
Once you complete your Franchise Tax Questionnaire using your FQ number, Texas will issue you an XT number. This becomes your primary ID for ongoing Texas LLC compliance.
What You Use Your XT Number For
Texas Public Information Report (PIR): Every Texas LLC must file this annually by May 15th. It’s basically Texas asking “Are you still in business and who owns you?”
Texas Franchise Tax Return: Only required if your LLC has gross receipts over $2.47 million annually. Most small and medium LLCs never file this.
How You Get Your XT Number
Texas will mail you an “Annual Report Reminder” about 6 weeks before your first Public Information Report is due. Your XT number will be printed in a box at the top of this reminder.
Timeline reality check: If you formed your LLC in 2025, your first PIR isn’t due until May 15, 2026. So you might not get your XT number until March or April 2026.
Need your XT number sooner? Call the Comptroller’s office at the same number (512-463-4402), but make sure you’ve completed your Franchise Tax Questionnaire first. They won’t issue an XT number until that’s done.
About Texas Franchise Tax (The Good News)
Here’s what most Texas LLC formation services don’t emphasize enough: most LLCs don’t pay franchise tax.
The franchise tax only applies to LLCs with gross receipts over $2.47 million per year. If your LLC makes less than that, you’ll still file the Public Information Report annually, but no franchise tax.
What “gross receipts” means: Total revenue before expenses. So if your LLC brings in $2.5 million but has $2.4 million in expenses, you’re still over the threshold.
The RT Number: For Sales Tax and Other Business Taxes
The RT number is different from FQ and XT numbers because you have to actively apply for it. Texas doesn’t automatically issue RT numbers—you get one when you register for specific business taxes.
When You Need an RT Number
Sales tax registration: If your LLC sells physical products or certain services to Texas customers, you need to collect and remit sales tax.
This includes:
- Retail sales (online or in-person)
- Wholesale to non-exempt buyers
- Certain digital products
- Taxable services (varies by industry)
Other business taxes that use RT numbers:
- Mixed beverage tax (bars, restaurants serving alcohol)
- Tobacco products tax
- Motor vehicle rental tax
- 911 surcharge fees
- Various industry-specific taxes
How to Get Your RT Number
You get an RT number by registering for a Texas Sales Tax Permit through the Comptroller’s website. The process is actually pretty straightforward:
- Complete the Texas Sales Tax Registration Application online
- Provide basic LLC information (name, address, EIN, business description)
- Submit the application (it’s free to register)
- Wait 2-3 weeks for your Sales Tax Permit to arrive by mail
- Your RT number will be on the permit
Jake’s tip: Register for sales tax before you make your first sale, not after. Texas doesn’t mess around with sales tax compliance, and penalties add up fast.
Common WebFile Number Mistakes I See
1. Using the wrong number for the wrong filing: Each number has a specific purpose. You can’t use your FQ number to file annual reports or your XT number for sales tax.
2. Ignoring the Franchise Tax Questionnaire: Just because most LLCs don’t owe franchise tax doesn’t mean you can skip the initial questionnaire.
3. Throwing away Comptroller mail: Unlike most government mail, everything from the Texas Comptroller’s office is important. File it, don’t trash it.
4. Not registering for sales tax when required: If you’re selling products in Texas, you probably need an RT number. Don’t wait until you get caught.
5. Mixing up annual report deadlines: Your PIR is due May 15th every year, regardless of when you formed your LLC.
Practical Timeline for New Texas LLCs
Here’s what to expect after your Texas LLC is approved:
Weeks 2-3: Welcome Letter arrives with FQ number
Week 4: Complete Franchise Tax Questionnaire using FQ number
Months 6-15: XT number arrives with first annual report reminder
As needed: Apply for RT number if you need sales tax registration
First annual report deadline: May 15th of the year following formation
Managing Your WebFile Numbers
Keep organized records: Create a file (physical or digital) with all your Comptroller correspondence. You’ll need these numbers for years to come.
Update your address: If you move your LLC’s address, notify the Comptroller immediately. Missing important mail because of an outdated address creates expensive problems.
Set calendar reminders: Texas annual reports are due May 15th every year. Missing this deadline results in penalties and can eventually lead to involuntary dissolution.
Save contact information: 512-463-4402 is the main Comptroller number. Save it in your phone—you’ll probably need it at some point.
WebFile System Navigation Tips
The actual WebFile portal: Once you have your appropriate WebFile number, you’ll use Texas’s online WebFile system for most filings.
What works well: The system is generally reliable and processes payments quickly.
What’s frustrating: The user interface feels like it was designed in 2005 (because it probably was). Be patient and double-check everything before submitting.
Browser compatibility: Use Chrome or Edge. I’ve seen the system get cranky with Safari and Firefox.
When to Call the Texas Comptroller
Definitely call if:
- You haven’t received expected mail after reasonable time periods
- You’ve lost important documents with WebFile numbers
- You’re unsure which WebFile number to use for a specific filing
- You’re getting error messages in the WebFile system
Have ready when you call:
- Your LLC’s exact legal name
- Formation date
- Current address on file
- Any WebFile numbers you already have
Best times to call: Tuesday through Thursday, 10 AM to 2 PM. Avoid Mondays (they’re busy catching up) and Fridays (reduced staffing).
The Bottom Line on Texas WebFile Numbers
Texas’s three-number system seems overcomplicated until you understand the logic: different numbers for different types of business with the state.
For most Texas LLCs:
- FQ number: Complete your initial questionnaire, then file it away
- XT number: Use for annual reports every May 15th
- RT number: Only needed if you collect sales tax or pay other business taxes
The key is staying organized and not ignoring mail from the Comptroller’s office. Miss important deadlines, and you’ll face penalties that are easily avoidable with basic attention to detail.
Your Texas WebFile Action Plan
Immediate priorities for new LLCs:
- Watch for your Welcome Letter with FQ number (2-3 weeks after formation)

- Set up a system to track annual report deadlines
Ongoing compliance:
- File your PIR annually by May 15th using your XT number
