Texas removes the personal income tax burden that defines tax life in most other major metros, and Austin founders, investors, and operators feel that benefit every paycheck. The trade-off is a margin-based franchise tax with four competing calculation methods, a sales tax regime that captures more services than people expect, and federal exposure that grows quickly when an Austin business scales. A CPA who works inside Comptroller rules every week is what turns those moving parts into a clean annual outcome.

Solo Filing With Standard Software
Filed independently with default federal deductions, no entity election explored, no retirement contribution scheduled, and no Texas Franchise Tax method comparison performed. Self-employment tax applies to the full schedule of net earnings, and the franchise margin defaults to whichever method the software selects rather than the one that yields the lowest lawful tax.
Working With an Austin CPA
The CPA elects S-Corp status to lower self-employment tax, opens and funds a SEP-IRA before December 31, runs every available franchise tax margin method to land on the lowest taxable margin, and applies industry-specific federal deductions the software ignored. Same gross income, materially smaller bill at year-end.

An Austin CPA pays for the engagement quickly when one of these four patterns appears in your year. Each is a place where Texas-specific rules diverge from what national tax software assumes, and where doing it yourself or relying on a generalist outside Texas reliably produces a return that is filed but not optimized.
For Austin entities above the 2026 no-tax-due threshold of $2.65 million in annualized total revenue, the Texas Franchise Tax is calculated on taxable margin, and the margin can be computed four ways: 70 percent of total revenue, total revenue minus cost of goods sold, total revenue minus compensation, or total revenue minus $1 million. The lowest of the four wins, and it is rarely the same answer across years as cost structures shift. A Texas-experienced CPA runs all four every cycle and documents the choice. A generalist or DIY filer typically runs one and stops. The standard rate is 0.75 percent (0.375 percent for retail and wholesale), and below $20 million in annualized revenue the EZ Computation at 0.331 percent is also available, though it locks out deductions and credits.
Texas does not limit sales tax to retail goods. Data processing services, information services, certain consulting and professional services, telecommunications, and a meaningful slice of SaaS arrangements fall inside the taxable services list under Texas Tax Code Chapter 151. Data processing carries a 20 percent statutory exclusion that softens the rate, but does not remove the obligation to register, collect, and remit. Austin's density of software companies, agencies, and IT consultancies means a large number of local businesses owe sales tax they have never collected, and Comptroller assessments on unregistered service providers regularly arrive with three to four years of back tax plus penalties and interest. A Texas-fluent CPA performs the taxability review before the assessment does.
Austin has been one of the fastest-growing major metros in the country, and the businesses growing inside it routinely outpace their own quarterly tax planning. Federal estimated tax safe harbors are based on the prior year, so a business that doubled its revenue between Q1 and Q4 owes a balance at filing that the safe harbor never captured. Self-employment tax thresholds, retirement contribution limits, and entity election break-evens all sit at specific revenue levels that pass without notice if the books are not being reviewed quarterly. A CPA running quarterly check-ins catches each threshold as the business crosses it, rather than presenting the full bill in April.
Property values across Austin, Round Rock, Cedar Park, and the wider Travis and Williamson County corridor have produced large embedded gains for owners who bought before the 2020 to 2024 surge. A sale without pre-closing planning sends a meaningful share of the proceeds to federal capital gains tax. The strategies that move this needle, including 1031 like-kind exchanges, opportunity zone investments, installment sale structuring, qualified small business stock exclusion under Section 1202, and cost segregation studies for rental properties, have to be set up before the deal closes. A CPA with active investor clients reviews the structure at letter-of-intent stage, not at filing time.
Plenty of firms list Austin as a service area without doing meaningful Texas-specific work. The credential check matters, but the deeper screen is what the firm actually files in volume and how often they are inside your numbers. Run these five filters before signing anything.
Austin CPA Selection Filters
5 / 5 Complete
Active CPA License Through the Texas State Board of Public Accountancy or IRS Enrolled Agent Status
Confirm the CPA license through the Texas State Board of Public Accountancy database or verify enrolled agent credentials through the IRS directory. Both authorize full representation before the IRS and the Texas Comptroller of Public Accounts in the event of an audit, notice, or compliance dispute. Anything below those credentials cannot represent you in either forum.
Regular Volume of Texas Franchise Tax and Sales Tax Filings
Ask how many Texas Franchise Tax reports the firm files in a typical year, whether they routinely run all four margin methods, and how many sales tax filings they handle for service businesses. A practitioner who files Texas returns weekly will catch sourcing, apportionment, and taxability issues that someone filing two or three a year will not.
Genuine Familiarity With Austin’s Industry Mix
Austin’s economy concentrates around software and SaaS, semiconductors, real estate development, music and entertainment, professional services, and a growing healthcare and biosciences cluster. A CPA whose existing book includes clients in your industry will know the deduction patterns, the typical Comptroller audit triggers, and the credit programs that apply, without needing a learning curve on your time.
Quarterly Engagement Cadence Built Into the Relationship
Texas filings cluster around the May 15 franchise tax deadline rather than April 15 alone, and federal estimated taxes hit four times a year. A CPA who only surfaces in March and April is missing the planning windows where decisions on entity election, retirement contributions, and margin method selection actually move the number. Look for explicit quarterly check-ins or, at minimum, a Q3 planning meeting.
Engagement Letter Defines Scope, Pricing, and Texas-Specific Work in Writing
Push for a written engagement that names every return on the docket (federal, franchise, sales tax, payroll where relevant), every advisory service bundled in, and what each piece costs. Capped hourly, fixed-fee with stated deliverables, or a tiered service shelf are all reasonable structures, provided the boundaries land on paper before kickoff. Texas franchise work in particular tends to attract scope creep, and a clear engagement letter saves both sides from arguments later.
| Filter | What to Verify |
| Credential | Texas CPA or IRS Enrolled Agent |
| Texas filing volume | Routine franchise and sales tax work |
| Engagement model | Quarterly planning plus filing |
| Industry alignment | Active clients in your Austin sector |
| Pricing transparency | Written engagement letter upfront |
If your CPA passes all five filters above, your federal return, franchise tax filing, and sales tax compliance are in solid hands. If something is still fuzzy, sort it out long before the May 15 franchise deadline. Once filing season is on top of you, the planning runway is gone and only paperwork is left.
Skipping state income tax removes one layer, but federal income tax, federal self-employment tax, the Texas Franchise Tax above the no-tax-due threshold, and Texas sales tax on a wide range of services all remain. A CPA earns the engagement back through entity structuring, margin method selection, retirement plan setup, and sales tax taxability work. The headline rate is zero. The total picture is anything but.
The franchise tax is a margin-based tax on most Texas business entities, calculated on taxable margin rather than net income. The 2026 no-tax-due threshold is $2.65 million in annualized total revenue. Below that, you do not owe franchise tax but you must still file an information report. Above that, the tax is calculated using the lowest of four margin methods (70 percent of revenue, revenue minus COGS, revenue minus compensation, or revenue minus $1 million) at 0.75 percent for most entities or 0.375 percent for retail and wholesale. The annual deadline is May 15.
Often, yes, even when founders assume otherwise. Texas treats data processing, information services, telecommunications, and many SaaS arrangements as taxable services under Chapter 151. Data processing receives a 20 percent statutory exclusion, but the obligation to register, collect, and remit still applies. Austin tech businesses that have grown without ever evaluating their sales tax position are common, and Comptroller back-tax assessments on unregistered service providers can cover several years plus penalties and interest.
Post-Wayfair economic nexus rules mean that crossing revenue or transaction thresholds in another state triggers registration and filing obligations there, even if you have no physical presence. An Austin business shipping to or selling SaaS into California, New York, Florida, or any other state may have triggered nexus without realizing it. A CPA experienced in multi-state work maps the exposure, registers where required, and integrates those filings with your Texas Franchise Tax return.
Often yes, once net business income reaches a level where the self-employment tax savings exceed the additional payroll, accounting, and administrative cost of running an S-Corp. The break-even varies by income level and benefits package, which is exactly the calculation a CPA runs in Q3 or Q4 before making the next-year election. Worth noting: Texas does not honor your federal S-Corp election for franchise tax purposes. The franchise tax applies to the entity regardless.
A bookkeeper records transactions and keeps the books current. A CPA prepares federal and franchise returns, plans for tax outcomes, advises on entity decisions, and represents you before the IRS and the Texas Comptroller in audits or disputes. Most growing Austin businesses run both: the bookkeeper feeds clean monthly numbers into the CPA, and the CPA uses those numbers to plan, file, and defend.
Pricing tracks complexity. A straightforward federal personal return sits at the lower end. A growing LLC carrying federal work, franchise tax, sales tax, payroll oversight, and quarterly advisory rises sharply from there. Get a written quote that itemizes each service and its fee before you commit, so the budget is settled and the scope is fixed before May rolls around.
