What Form 05-164 Is For
Form 05-164, officially called the Texas Franchise Tax Extension Request, allows businesses subject to the Texas franchise tax to extend their filing deadline. The Texas Comptroller's office uses this form to grant additional time to prepare and submit franchise tax reports—either annual reports due each May 15 or final reports due within 60 days of ending Texas business operations.
The extension doesn't eliminate your tax obligation or delay payment requirements. Instead, it shifts the report filing deadline while requiring you to estimate and pay most or all of what you'll owe. Think of it as buying time to finalize your numbers while demonstrating good faith by paying upfront. The Comptroller tentatively grants extensions upon receiving a timely request with appropriate payment, giving businesses until August 15 or November 15 (depending on payment method and timing) to submit their complete reports.
Texas businesses can request extensions through multiple channels: filing Form 05-164 by mail, submitting online through the Comptroller's Webfile system, or using TEXNET for electronic funds transfers. Entities that paid substantial franchise taxes in prior years ($10,000 or more) must use electronic payment methods. While the paper form remains available, the Comptroller discourages submitting Form 05-164 when making online extension payments, as the electronic submission automatically serves as your extension request.
When You’d Use Form 05-164
Late or Timing-Related Situations
You'd file Form 05-164 when you realize your business cannot complete its franchise tax report by the original due date—typically May 15 for annual reports. Common scenarios include waiting for year-end financial statements, dealing with complex business restructuring, managing multiple entity consolidations, or simply needing additional time to ensure accuracy in your calculations.
Annual Report Extensions
For annual reports, non-EFT payers (those who paid less than $10,000 in franchise tax during the previous state fiscal year) must submit their extension request on or before May 15. This single extension moves their filing deadline to November 15. Businesses required to pay by Electronic Funds Transfer have a two-stage extension process: the first extension (requested by May 15) extends the deadline to August 15, and a second extension (requested by August 15) can push the final deadline to November 15.
Final Report Extensions
Final reports follow different timing. When your business ends Texas operations—whether through dissolution, merger, or losing Texas nexus—you must file a final franchise tax report within 60 days. If you need more time, submit your extension request on or before that 60-day deadline. The extension grants an additional 45 days beyond your original due date, giving you 105 total days from ending operations.
Situations Where This Form Does NOT Apply
The extension form is not used for amended returns. If you've already filed your franchise tax report but later discover errors, you'll file an amended report using the standard franchise tax forms, not an extension request. Similarly, if you miss the original deadline without requesting an extension, you cannot retroactively file Form 05-164 to avoid penalties—at that point, you must file your delinquent report immediately and may request penalty waivers separately through the Comptroller's waiver process.
Key Rules or Details for Filing
Payment Requirement Rules
The cornerstone rule for valid extensions is the payment requirement. Generally, you must pay either 100 percent of the tax you paid last year or 90 percent of what you'll owe this year. The 100 percent option offers simplicity—if you paid $5,000 last year, pay $5,000 with your extension and you're covered until the extended deadline. The 90 percent option requires estimating your current year liability, which can be tricky but potentially saves money if your tax obligation decreased.
Limitations on the 100 Percent Rule
Important limitations apply to the 100 percent payment option. Businesses filing their first annual franchise tax report cannot use this option because they have no prior year payment to reference. Similarly, if your entity was part of a combined group last year but is filing separately this year, you cannot use the 100 percent option. However, combined groups that remain combined can use the 100 percent option even if individual members changed.
No-Tax-Due Entities
Entities under the no-tax-due threshold present a special case. If your business had annualized revenue below $2.47 million (for reports due in 2024 and later) and only filed an information report last year, you can request a no-payment extension. This makes sense because zero tax last year means 100 percent of last year's tax equals zero. Simply file the extension request without payment to extend your information report filing deadline.
Deadline and Timing Rules
Timing is absolute. Your extension request must be received or postmarked on or before the original due date. If May 15 falls on a weekend or legal holiday, the next business day becomes the deadline. Electronic payments through Webfile must be submitted by 11:59 p.m. Central Time on the due date. TEXNET users must complete payment information by 8 p.m. Central Time on the business day before the due date. Missing these deadlines by even one day invalidates your extension.
Step-by-Step (High Level)
Step One: Determine Your Extension Type and Deadline
Check whether your entity paid $10,000 or more in franchise taxes during the previous state fiscal year (September 1 through August 31). This determines whether you're an EFT mandatory payer and affects your extension options. Calculate whether you're filing an annual report (due May 15) or final report (due 60 days after ending Texas operations).
Step Two: Calculate Your Extension Payment
Decide between paying 100 percent of last year's tax or 90 percent of this year's estimated tax. Review last year's franchise tax report to find the tax amount paid. If estimating this year's liability, calculate based on your current revenue and anticipated margins. Remember that first-year filers and entities moving from combined to separate filing cannot use the 100 percent option.
Step Three: Choose Your Filing Method
Non-EFT payers can use Webfile, approved software providers, or paper Form 05-164. EFT mandatory payers ($10,000-$499,999 in prior year taxes) should use Webfile or approved software. Entities that paid $500,000 or more must use TEXNET exclusively. Gather your 11-digit Texas taxpayer number and accounting year-end date before beginning.
Step Four: Submit Your Extension Request and Payment
For Webfile users, log into the Texas Comptroller's secure system, select the franchise tax extension option, enter your entity information, specify your payment amount, and submit electronically. If using paper Form 05-164, complete all required fields including entity name, taxpayer number, report year, accounting year end, and payment amount. Mail the form with your check to the address printed on the form, ensuring it's postmarked by the deadline. TEXNET users should make their payment using tax type code 13080 (Franchise Tax Extension) and skip submitting a separate Form 05-164.
Step Five: Retain Confirmation Documentation
Save your Webfile confirmation number or TEXNET transaction receipt. For paper submissions, keep copies of your completed form and proof of mailing. This documentation proves timely filing if questions arise later. The Comptroller typically processes extensions quickly, but confirmation provides peace of mind.
Step Six: File Your Report by the Extended Deadline
Mark your calendar for the extended due date—November 15 for most annual reports, August 15 for EFT payers taking only the first extension, or 45 days beyond the original due date for final reports. If your extension payment falls short of 90 percent of your actual tax liability, you'll owe penalties and interest on the shortfall, so file and pay any balance as soon as possible.
Common Mistakes and How to Avoid Them
Mistake One: Submitting Paper Forms After Electronic Payments
Many businesses pay their extension electronically through Webfile or TEXNET, then unnecessarily mail Form 05-164 as well. This creates duplicate records and processing confusion. The electronic payment automatically serves as your extension request. Only submit paper Form 05-164 if you're paying by check.
Mistake Two: Underpaying the Extension Amount
Businesses often miscalculate 90 percent of current year taxes or accidentally reference the wrong prior year amount. If your extension payment doesn't meet the 90 percent threshold, you'll face penalties on the unpaid portion from the original due date plus penalties on the remaining 10 percent from the extended due date. Double-check your calculations before submitting. When in doubt, paying slightly more than required provides a safety margin.
Mistake Three: Missing the Deadline
Extensions requested even one day late are invalid, exposing you to late filing penalties. The $50 late report penalty applies regardless of whether you owe tax. Set reminders well before the deadline to allow time for processing issues, bank delays, or technical problems. For TEXNET users, remember the 8 p.m. deadline on the business day before the due date—not on the due date itself.
Mistake Four: First-Year Filers Using the 100 Percent Option
New businesses filing their first annual franchise tax report cannot use the 100 percent of prior year tax option because no prior year exists. They must estimate and pay 90 percent of current year liability. Similarly, entities separating from a combined group cannot use their prior combined group's payment as reference.
Mistake Five: Assuming the Extension Delays Payment
Unlike some federal tax extensions, Texas franchise tax extensions require paying most of your liability upfront. Businesses sometimes file extension requests with little or no payment, thinking they can pay later. This misunderstanding leads to penalties and interest charges. The extension gives you time to file paperwork, not time to pay taxes.
Mistake Six: Neglecting Second Extensions for EFT Payers
Mandatory EFT payers must request a second extension by August 15 if they need until November 15 to file. Many businesses request the first extension, assume they're covered until November 15, and miss the August 15 second extension deadline. Mark both deadlines if you're an EFT payer needing maximum time.
What Happens After You File
Extension Approval and Status
Once the Comptroller receives your timely extension request with appropriate payment, your extension is tentatively granted. ""Tentatively"" means the extension remains valid unless your final report reveals you didn't pay enough with the extension. You won't receive formal approval letters in most cases—your confirmation number or payment receipt serves as evidence of your extension.
Preparing Your Report
Between filing your extension and the extended deadline, focus on preparing an accurate franchise tax report. Gather complete financial records, reconcile revenue figures, determine the appropriate margin calculation method, and verify all entity information remains current. The extended time should result in a more accurate return, reducing the likelihood of future amendments or audits.
Final Filing and Payments
When filing your report by the extended deadline, you'll calculate your actual franchise tax liability and pay any remaining balance. If your extension payment exceeded your actual liability, you can either request a refund or credit the overpayment toward next year's franchise tax. Payments made with extension requests earn interest if refunded, though most businesses prefer applying credits forward.
Penalties and Interest
Penalties and interest apply in specific situations. If your extension payment falls short of 90 percent of actual tax due, penalties and interest accrue on the shortfall from the original due date. If you pay at least 90 percent with the extension but owe a balance with your report, penalties and interest apply only to the remaining 10 percent, calculated from the extended due date. The statutory penalty is 5 percent if paid within 30 days of the applicable deadline, increasing to 10 percent after 30 days. Interest begins accruing 61 days after the applicable due date at a variable rate set annually (prime rate plus 1 percent).
Missing the Extended Deadline
Missing the extended deadline creates serious consequences. The $50 late report penalty applies even if you owe no additional tax. Late payment penalties of 5 to 10 percent plus interest accumulate quickly. The Comptroller may initiate collection actions including liens, asset seizures, and permit suspensions. File your report as soon as possible if you miss the deadline, then consider requesting a penalty waiver if you have reasonable cause for the delay.
FAQs
Can I file an extension if I don't owe any franchise tax?
Yes. If your entity falls under the no-tax-due threshold but must file an information report, you can request a no-payment extension. This extends your Public Information Report or Ownership Information Report deadline from May 15 to November 15 without requiring payment since you owed no tax in the prior year. Simply file the extension request on or before the original deadline.
Does filing an extension increase my chances of being audited?
No. Extension requests are routine business tools that do not trigger audits or raise red flags. The Comptroller recognizes that businesses often need additional time to ensure accuracy. Filing an extension demonstrates responsibility by acknowledging you need more time rather than rushing an inaccurate report or missing deadlines entirely.
Can combined groups file a single extension for all members?
Yes. A reporting entity filing on behalf of a combined group can submit one extension covering the entire group. However, you must also file Form 05-165, the Extension Affiliate List, identifying all affiliated entities included in the extension. EFT mandatory combined groups follow the same two-stage extension process as individual entities.
What if I paid 90 percent with my extension but my actual tax ends up higher than estimated?
You'll owe the balance when filing your report by the extended deadline. As long as your extension payment met or exceeded 90 percent of the final liability, penalties and interest only apply to the remaining 10 percent from the extended deadline forward. However, if your estimate was too low and your payment didn't reach 90 percent, penalties and interest apply to the shortfall from the original deadline.
Can I get a refund if I overpay with my extension?
Yes. If your extension payment exceeds your actual franchise tax liability, you can request a refund when filing your report or apply the credit toward next year's franchise tax. Many businesses choose the credit option for simplicity. If you request a refund, the Comptroller will issue payment after processing your report, typically including interest on the overpayment from the original due date.
What happens if May 15 falls on a weekend?
When the franchise tax due date falls on a Saturday, Sunday, or legal holiday, the next business day becomes the official deadline. For example, if May 15 falls on Saturday, your deadline extends to Monday, May 17 (assuming Monday isn't a holiday). This grace period applies equally to extension requests and final report filings.
If I'm required to use TEXNET, do I still need to file Form 05-164?
No. Entities required to pay via TEXNET ($500,000 or more in prior year franchise taxes) should not submit Form 05-164. Your TEXNET payment using tax type code 13080 serves as both your payment and extension request. Submitting a paper form creates unnecessary duplication and potential processing confusion. The only exception is if you're requesting a second extension with no additional payment—in that case, use Webfile or Form 05-164 to document your request.
