What the Form Is For
Form 05-164 is the official document businesses use to request additional time to file their Texas franchise tax reports. The Texas franchise tax is a privilege tax that most entities formed in Texas or doing business in Texas must pay annually, including corporations, limited liability companies, partnerships, banks, and professional associations. The standard deadline is May 15 each year, but Form 05-164 allows eligible entities to extend their filing deadline to November 15—a full six additional months.
Think of this form as your official request for a timeout. However, it's important to understand that an extension to file is not an extension to pay. You still need to estimate and pay most of what you'll owe by the original May deadline. The extension simply gives you more time to complete the paperwork and finalize the exact numbers.
According to the Texas Comptroller's guidance on extensions, the extension will be "tentatively granted" upon receipt of a timely request with the appropriate payment. The keyword here is "tentatively"—your extension is valid only if you meet all payment requirements and file by the original due date.

FAQs
Can I file an extension if my business owes no franchise tax?
Yes. If your business is under the no tax due threshold or owed zero tax last year, you can file a no payment extension request. Simply submit Form 05-164 by May 15 without including a payment. This extends your deadline for filing required information reports to November 15.
What if I can't estimate 90 percent of my tax liability accurately?
Make your best reasonable estimate based on available financial information. It's better to slightly overestimate than underestimate. If your actual tax liability is lower, you'll receive a refund or credit. If you underestimate, penalties may apply.
If I was part of a combined group last year, can I use the 100 percent payment option?
No. Entities previously included in a combined group cannot use the 100 percent option when filing separately. You must estimate and pay at least 90 percent.
Do I need to file Form 05-164 if I pay online?
No. An online payment through Webfile serves as your extension request.
What happens if May 15 falls on a weekend or holiday?
The deadline moves to the next business day.
Can I request an extension for a final franchise tax report?
Yes. Final reports can be extended by 45 days using Form 05-164-F.
If my payment doesn't meet 90 percent, is my extension invalid?
The extension remains valid for filing, but penalties and interest will apply to the unpaid portion.
