What the Form Is For
Texas Form 05-164, officially titled ""Texas Franchise Tax Extension Request,"" is the paper document businesses use to request additional time to file their annual or final franchise tax reports with the Texas Comptroller of Public Accounts. The franchise tax itself is a privilege tax imposed on entities formed in Texas or doing business in the state, including corporations, limited liability companies, partnerships, and most other legal business entities (excluding sole proprietorships and general partnerships composed entirely of natural persons).
When you file Form 05-164, you're asking the state to move your filing deadline from the original due date—typically May 15 each year—to a later date. For most businesses not required to use Electronic Funds Transfer (EFT), this means extending the deadline to November 15. The extension gives you extra time to gather financial records, complete calculations, or address unexpected circumstances that prevent timely filing. However, an extension to file is not an extension to pay—you must still submit payment with your extension request based on either 90 percent of the current year's estimated tax or 100 percent of the prior year's tax.
The Texas Comptroller strongly encourages businesses to file extensions electronically through Webfile rather than using the paper Form 05-164. In fact, if you make an online extension payment through Webfile, you should not submit the paper form at all. The paper form remains available primarily for businesses that cannot access online filing or prefer traditional filing methods.
When You’d Use It
Late or Timing-Related Situations
You would file Form 05-164 when you cannot meet the original franchise tax report deadline, which is May 15 each year (or the next business day if May 15 falls on a weekend or legal holiday). Common situations include needing extra time to compile financial records, waiting for federal tax information, dealing with accounting complexities in combined group reporting, or experiencing unexpected business circumstances like personnel changes or system failures.
The extension request must be submitted or postmarked on or before the original due date to be valid. If May 15 is your deadline, the extension form and payment must reach the Comptroller's office or be postmarked by May 15. Missing this deadline means you lose the opportunity for an extension, and your report becomes late immediately, triggering penalties.
Final Reports
For final reports—filed when a business terminates, merges, converts, or ceases doing business in Texas—the same extension rules apply. Texas entities must file their final report in the year they terminate, while out-of-state entities must file within 60 days of ending Texas nexus. The extension for a final report extends the due date by 45 days from the original deadline.
Important Limitation
Importantly, Form 05-164 is not used for amended returns. If you discover errors on a filed franchise tax report, you follow different procedures for amendments. The extension form also doesn't apply to information reports alone, though entities under the no tax due threshold can file a no-payment extension to extend their information report due date to November 15.
Key Rules or Details
Payment Requirements
The most critical rule about Texas franchise tax extensions centers on payment requirements. To receive a valid extension, you must pay either:
- 90 percent of the current year’s estimated tax
- 100 percent of the prior year’s reported tax
This payment must accompany your extension request. You can choose whichever option results in lower payment.
Restrictions on the 100% Option
- First-time filers cannot use the 100 percent option
- Entities changing from combined to separate filing cannot use it
- Entities with zero tax last year may file a no-payment extension
Electronic Payment Requirements (EFT)
Businesses that paid:
- $10,000–$499,999.99 → must use Webfile

Common Mistakes and How to Avoid Them
Confusing Filing vs. Payment Extensions
An extension to file does not extend payment. Always include the required payment.
Missing the Deadline
Late submissions invalidate the extension. Plan at least one week ahead.
Incorrect Payment Calculations
Underpaying leads to penalties. Always verify:
- Prior year return
- Current year estimate
Using Outdated Forms
Always download the correct year-specific form.
Ignoring EFT Requirements
Paper filing when EFT is required can trigger a 5% penalty.
Missing Form 05-165 for Groups
Combined groups must include affiliate details.

FAQs
Can I file an extension without making any payment?
Yes, but only if your prior year tax liability was zero. In that case, the 100 percent prior-year option results in a zero payment. You must still file the extension on time to qualify.
What happens if my extension payment exceeds my actual tax?
The excess becomes a credit. It can be applied to your return, refunded, or carried forward. Refunds require a formal request.
Can combined groups use the 100 percent prior-year option?
Yes, if the group filed as a combined entity last year. If filing structure changes, eligibility may be affected.
What if I missed the original deadline?
You cannot file a late extension. Your return is immediately considered late, and penalties begin applying.
Do I need a separate extension for information reports?
No. Form 05-164 extends both the franchise tax report and any associated information report.
How do I know if I must use EFT?
If you paid $10,000+ in franchise tax during the prior fiscal year, EFT is required. Payment method depends on the amount.
Does filing an extension replace my tax report?
No. The extension only delays the deadline. You must still file the full franchise tax report by the extended due date.
