Why Texas LLC Formation Franchise Tax Mechanics Catch Out-of-State CPA Firms
Texas LLC formation franchise tax mechanics look familiar from the outside. File a certificate, pay $300, get an EIN, move on. Then your client asks your team about a series LLC structure for a real estate portfolio, your firm realizes the no-tax-due threshold just changed again, and the May 15 deadline is six weeks away with no PIR drafted by your preparers. At BusAcTa Advisors, we handle Texas entity setup and ongoing franchise tax filings every quarter behind US CPA partners, and the out-of-state firms inheriting Texas clients usually need a refresher from us on the four or five wrinkles that make Texas different from the states they're used to.
Here's the honest version. Texas has no personal income tax, which makes it a popular entity-formation state for your clients. But it has a 0.75% margin-based franchise tax with a generous no-tax-due threshold, a unique series LLC statute that's misunderstood for tax purposes, a mandatory Public Information Report even when zero tax is owed, and a veil-piercing risk pattern your firm should know cold. This guide walks through the five rules CPA firms with Texas clients need in 2026.
This is general information about Texas LLC formation and franchise tax, not legal or tax advice for any specific filer. Always confirm current rates, thresholds, and series LLC mechanics with the Texas Secretary of State, the Texas Comptroller, and qualified Texas counsel before your firm signs off on entity decisions.
Rule 1: Texas LLC Formation Mechanics (Form 205, BOC Chapter 101)
Answer first: forming a Texas LLC requires filing a Texas Form 205 Certificate of Formation with the Texas Secretary of State and paying a $300 filing fee. The LLC is governed by Title 3, Chapter 101 of the Texas Business Organizations Code (BOC). Your client's entity exists perpetually unless their certificate states otherwise.
Three formation items your firm should walk every Texas client through:
Registered agent and registered office. The Texas LLC registered agent must consent (in writing or electronically) before being named. The registered office address must be a street address where service of process can occur during business hours, not a P.O. box, mailbox service, or telephone answering service (BOC §5.201).
Initial mailing address. Required for all filing entities since January 1, 2022. Easy to miss on the form.
Members. A Texas LLC needs at least one member. Your client's members can be individuals, other entities (corporations, partnerships, other LLCs), trusts, or foreign persons. No residency requirement.
A brief note on the TX LLC vs corporation choice your firm may also need to advise on: Texas LLCs and Texas corporations both pay the franchise tax at the same rate, but LLCs offer more flexibility on internal governance and pass-through federal treatment by default. The Form 205 takes about 5 minutes to complete once the inputs are gathered. The SOS turnaround is typically 3-5 business days for online filings. Have you confirmed your client's registered agent will actually be reachable during business hours at the address your team listed? It's the single most common gap we see when we onboard a new Texas client mid-stream.
Rule 2: The Texas Series LLC Option Is Powerful, Often Misunderstood for Tax
The Texas series LLC is one of the most flexible entity structures in the United States. Under the Texas BOC 101 series LLC framework (BOC Subchapter M, §§101.601 to 101.621), a single Texas LLC can establish multiple series, each with separate assets, separate rights, separate obligations, and (if records are maintained correctly) separate liability protection from the other series and from the master LLC.
Two key types of series:
Protected series: Created via internal documents (company agreement plus notice in the certificate of formation). No filing with the Secretary of State required.
Registered series: Filed separately with the SOS (since SB 1523 effective June 1, 2022). Has additional formal recognition, including the ability to obtain its own assumed name certificate at the state level.
The tax piece is where most preparers get tripped up. For Texas franchise tax purposes, a series LLC is treated as a single legal entity. The master files one franchise tax report and one Public Information Report under one taxpayer identification number, covering all series. The series your firm sets up for them don't file separately at the state level.
The IRS treats each series as a potentially separate entity for federal tax purposes (Treasury Regulation Section 301.7701). A Texas series LLC may file one Texas franchise tax return and multiple federal returns, depending on how each series is structured. The federal-state mismatch is the most common error we catch on series LLC returns prepared by out-of-state firms.
For your client's real estate portfolio with five rental properties, a series LLC can hold each property in a separate series, with each series isolated from the others' liabilities. But the segregation is only real if your firm maintains separate records, separate bank accounts, and separate accounting for each of their series. Has your firm reviewed the recordkeeping discipline for every series LLC client in its book?
Rule 3: The Texas Franchise Tax, the $2.65M Threshold, and the May 15 Deadline
The Texas LLC franchise tax applies to nearly every LLC organized or doing business in Texas, regardless of federal classification. Your client's single-member LLC, your multi-member LLC client, or your S-corp-electing LLC client all pay Texas franchise tax at the entity level. Texas doesn't recognize the federal S-corp election for franchise tax purposes.
Three numbers your firm should hold in mind for 2026:
For your clients above the threshold, the taxable margin is calculated using the lowest of four methods your team should run: 70% of total revenue, total revenue minus cost of goods sold, total revenue minus compensation (capped per employee), or total revenue minus $1 million. Your team should run all four for every above-threshold client your firm prepares for and document the choice in your workpapers. The EZ Computation is simpler but disqualifies from the R&D and other credits, which often matters more than the simplification benefit.
The no-tax-due threshold jumped to $2.65 million for the 2026 report year (up from $2.47 million for 2024 and 2025 reports). The previous threshold under Texas SB 3 of 2023 already more than doubled the pre-2024 figure of $1.23 million. Your firm should re-verify each of your clients' status against the current year's threshold annually, especially for the clients sitting near the line.
Rule 4: The Public Information Report Is Mandatory Even Below the Threshold
This is the trap that catches firms inheriting Texas clients from out-of-state CPAs. The old No Tax Due Report (Form 05-163) was discontinued for reports due on or after January 1, 2024. But your client still has to file a Public Information Report (Form 05-102) annually with your firm's help, even when revenue is below the no-tax-due threshold and zero franchise tax is owed.
What goes on the Texas PIR Form 05-102:
Officer, director, member, and manager information. The PIR captures who's in charge of the entity. This information is forwarded to the Texas Secretary of State and displayed publicly through the Comptroller's Taxable Entity Search.
Registered agent confirmation. The PIR shows the current registered agent, but the PIR cannot update the registered agent. Agent changes are filed separately on Form 401 with the SOS ($15 fee).
Filing officer signature. An officer, director, or other authorized person signs.
Even if your client owes zero franchise tax, skipping the PIR triggers a $50 penalty and ultimately forfeiture of the entity's right to transact business in Texas. Once forfeited, the LLC loses the right to sue or defend in Texas courts, and every officer, member, and manager becomes personally liable for certain entity debts under Texas Tax Code §171.255.
Texas LLCs your firm sets up don't file a PIR in their formation year when they first become subject to franchise tax. The first PIR is due May 15 of the year after the entity became subject to the tax. For an LLC formed in February 2026, the first PIR is due May 15, 2027. Have you flagged the calendar for every newly formed Texas client your firm onboarded in 2025 or 2026?
Rule 5: Veil-Piercing Risk Especially Hurts Series LLCs
Texas LLC liability protection is established under BOC §101.114, which generally provides that members and managers of an LLC are not liable for the entity's debts. Veil-piercing in Texas requires a creditor to demonstrate something like actual fraud, undercapitalization, alter-ego conduct, or commingling that makes the entity indistinguishable from its owners.
For series LLCs, the veil-piercing risk compounds. The liability segregation between series is only real if the records demonstrate it. BOC §101.603(b) requires that assets and liabilities of each series be maintained "in a manner so that the assets of the series can be reasonably identified by specific listing, category, type, quantity, or computational or allocational formula or procedure." Sloppy bookkeeping can destroy the segregation.
Three operational items your firm should enforce on every Texas series LLC client:
Separate bank accounts per series. Each series should hold its own funds. Sweeping balances between series at year-end without proper documentation destroys the segregation.
Separate accounting books per series. Your team should maintain distinct general ledgers, distinct revenue and expense accounts, and distinct asset records per series your client operates.
Series-specific contracts. When your client's master LLC enters a lease, a vendor contract, or a loan, the document should clearly identify which series is the contracting party. Generic "Master LLC and subsidiaries" language is a veil-piercing invitation.
The veil-piercing risk isn't theoretical. Texas courts have pierced the corporate veil in cases of egregious commingling, even where the entity nominally complied with BOC formalities. For your firm's real estate-heavy clients with multiple series, the cost-benefit of disciplined recordkeeping is overwhelming for them.
Filing Mechanics, 2026 Changes, and the Workflow
Three operational items round out the Texas LLC workflow your firm will run on every Texas client:
Webfile is the primary channel. The Texas Comptroller's Webfile system handles franchise tax reports, PIRs, and extensions. Paper filings are technically allowed but processed significantly slower.
Extension to November 15. Filing Form 05-164 by May 15 extends the franchise tax report and PIR deadline to November 15. The extension request itself is mandatory; the deadline doesn't extend automatically.
2026 IRC conformity changes. The Texas Comptroller adopted updated IRC conformity rules for the 2026 report year, including expanded depreciation options. Fixed assets acquired after January 19, 2025 may qualify for full expensing at the Texas level, more closely matching federal bonus depreciation.

Getting Texas LLC Formation and Franchise Tax Right in 2026
Your firm's Texas LLC formation franchise tax workflow is straightforward at the Secretary of State level. The real complexity for your firm sits in the franchise tax mechanics, the series LLC federal-state mismatch, the mandatory PIR even below the threshold, and the veil-piercing discipline you'll need to enforce for multi-series structures. Out-of-state CPA firms inheriting Texas clients almost always need a refresher from your team on at least one of these rules before their first May 15 filing.
