Texas businesses that spend money on research and development just got a rare bit of good tax news: as of January 1, 2026, the state's R&D franchise tax credit rate jumped from 5% to 8.722% — an increase of roughly 75% — and for the first time, qualifying small businesses can get the credit paid out as a cash refund instead of just carrying it forward against future tax bills they may not owe for years.
If your company does any kind of product development, engineering, software work, or process improvement in Texas, this rewrite of Subchapter T of the state's franchise tax code changes the math on whether it's worth formally claiming the credit at all — especially if you've skipped it in the past because your franchise tax liability was too small to make it worthwhile.
The Old System Wasn't Working for Small Companies
Texas has offered some form of R&D tax incentive since 2014, but the previous version had a structural problem: it only helped companies that owed enough state franchise tax to actually use the credit. A profitable ten-year-old manufacturer with real tax liability could benefit. A two-year-old software startup burning cash and owing little or no franchise tax couldn't — the credit just sat there, unused, carried forward year after year with no cash benefit when the company needed it most.
Businesses also had to choose between two mutually exclusive options: the franchise tax credit, or a sales and use tax exemption on equipment purchased for R&D. Many smaller companies defaulted to the equipment exemption because the immediate savings on a lab bench or a server rack felt more tangible than a credit against a tax bill they might not owe.
The legislature's rewrite — commonly referenced by its bill number, SB 2206 — addresses both problems at once.
What Actually Changed
The rate nearly doubled. The standard credit rate rose from 5.000% to 8.722% of qualifying Texas research expenditures. Research conducted in partnership with a Texas public university or other institution of higher education qualifies for an even higher enhanced rate of 10.903%, up from 6.250% previously.
It's now refundable for the businesses that need it most. This is the headline change. A business can apply for the refundable version of the credit — meaning the state pays it out in cash rather than only letting you offset future franchise tax — if it meets either of these conditions:
- Small business status: annualized total revenue of $2.65 million or less, which lines up with the state's existing "no tax due" franchise tax threshold.
- New veteran-owned business status: qualifying veteran-owned businesses during their first five years of operation (Texas already exempts many new veteran-owned businesses from franchise tax entirely during this window).
For a pre-revenue or early-revenue startup that's investing heavily in product development but has no franchise tax bill to offset, this is the difference between a credit that's theoretical and one that shows up as actual cash.
Definitions now track federal Form 6765. Qualifying research expenses are now defined by direct reference to the same rules businesses already use to calculate the federal R&D credit on IRS Form 6765. Previously, Texas maintained its own separate definitions, which meant double the documentation burden and more room for a state auditor to challenge an expense that the IRS had already accepted. Aligning the two reduces recordkeeping work and, in theory, audit risk — you're defending one set of numbers instead of two.
The credit is now permanent. Instead of being subject to periodic legislative renewal (a real risk for any state tax incentive), the credit is written into law without a sunset date, which makes it usable for multi-year R&D and capital planning rather than something you have to hedge against expiring.
You have to give something up. In exchange for the richer credit, the legislature repealed the parallel sales and use tax exemption on depreciable equipment purchased for R&D (the exemption businesses could previously elect instead of the credit). The repeal applies to equipment purchased on or after January 1, 2026. If your R&D work is equipment-heavy — a hardware startup buying test benches, a biotech buying lab instruments — you'll pay sales tax on that equipment going forward and need to lean on the bigger, refundable franchise credit to make up the difference.
How the Credit Is Actually Calculated
The formula hasn't gotten simpler, just richer. In general terms:
- Take your qualifying Texas research expenses for the current period.
- Subtract 50% of the average qualifying research expenses from the prior three tax periods.
- Multiply the result by 8.722% (or 10.903% for university-collaborative research).
If you have no qualifying research expenses in one or more of the three prior periods — which is common for a young company — the calculation simplifies to 4.361% (half the standard rate) of the current period's qualifying expenses.
A few mechanics carry over unchanged from the old law and are easy to miss:
- The credit can only offset up to 50% of franchise tax liability in a given period.
- Unused credit still carries forward for 20 years.
- The credit is nontransferable — you can't sell it to another company the way some states allow with certain energy or film credits.
What This Means If You Haven't Claimed the Credit Before
A lot of small Texas businesses never bothered to claim the R&D franchise credit because the payoff wasn't worth the paperwork: modest savings against a tax bill that was often near zero anyway. That calculus has changed for two distinct groups:
- Companies under the $2.65 million no-tax-due threshold now have a real reason to look at this — a refundable credit is cash in the bank, not a number on a schedule that never gets used.
- Companies that do qualify for real franchise tax liability get a materially bigger offset than before, at a rate that's nearly 75% richer than the old one.
Either way, the first step is figuring out whether the work you're already doing counts as "qualified research" under the federal Section 41 / Form 6765 definitions Texas now borrows — this typically covers activities aimed at developing or improving a product, process, formula, or software, where you're resolving technical uncertainty through a process of experimentation. It does not need to be groundbreaking or patent-worthy; incremental engineering and iterative software development regularly qualify.
The Bookkeeping Side Nobody Talks About
None of this credit is worth anything if you can't substantiate it — and substantiation is a recordkeeping problem, not a tax problem. To defend a research expense claim (in Texas or with the IRS), you generally need to show:
- Wage records tied to specific projects, not just a payroll total — which employees worked on which qualifying activities, and roughly what percentage of their time went to it.
- Contractor and supply costs coded separately from general operating expenses, so they can be pulled out and totaled by project rather than reconstructed after the fact.
- A contemporaneous trail connecting the expense to the technical uncertainty being resolved — project notes, ticket systems, or engineering logs that show the "process of experimentation," not just an expense hitting the books.
This is exactly the kind of thing that's painless if you set it up from day one and painful if you try to reconstruct it during tax season. Tagging R&D-related transactions with a project or cost-center identifier as you record them — rather than lumping everything into a generic "engineering" or "software" expense account — turns a stressful year-end scramble into a query you can run in minutes.
Simplify Your Financial Management
Claiming a credit like this well starts with books that make the qualifying expenses easy to find, not a spreadsheet reconstructed under deadline pressure. Beancount.io provides plain-text accounting that gives you complete transparency and control over your financial data — every transaction is tagged, version-controlled, and queryable, so pulling together a year's worth of R&D wage and supply costs for a tax credit claim is a matter of running a filter, not an archaeology project.
