Texas has no personal or corporate income tax — but that doesn't mean no state business tax. The Texas franchise tax, a margin-based privilege tax, applies to most entities doing business in the state, and Texas sales tax rules on construction materials carry their own real complexity. Construction bookkeeping for an Austin contractor needs to track both correctly.
This guide covers what's genuinely different about construction cost accounting for a Texas contractor: the franchise tax structure and sales tax treatment on construction materials. If you build in Austin or elsewhere in Texas, this is for you.
1. The Franchise Tax: A Margin Tax, Not an Income Tax
No state income tax doesn't mean no state business tax. Texas imposes a franchise tax — often called the margin tax — under Texas Tax Code Chapter 171, calculated on taxable margin rather than net profit.
TEXAS FRANCHISE TAX: WHAT AUSTIN CONTRACTORS NEED TO KNOW
A margin tax, not an income tax — confirm current thresholds and rates with the Texas Comptroller
Not an income tax | Texas has no personal or corporate income tax — the franchise tax is a separate, entity-level privilege tax under Texas Tax Code Chapter 171 |
Based on margin, not profit | Calculated from gross revenue using one of several statutory deduction methods — a business can owe franchise tax even in a loss year |
A revenue threshold applies | Entities below an inflation-adjusted annual revenue threshold owe no tax, though the exact figure changes periodically — confirm the current threshold with the Texas Comptroller |
Filing may still be required | Even entities below the threshold may have reporting obligations — confirm your specific requirement |
⚠ RED FLAG: Because franchise tax is based on margin rather than net income, a Texas construction business can owe franchise tax in a year with thin margins, and the calculation method chosen can meaningfully change what's owed. Confirm current thresholds, rates, and the right computation method for your business with a CPA or the Texas Comptroller. |
2. Sales Tax on Construction Materials Is Genuinely Complex
Texas sales tax treatment of construction materials depends on factors like whether the contract is for new construction versus improvement to existing real property, and whether the contractor is acting as the ultimate consumer of materials or reselling them. Construction bookkeeping should track material purchases and job type consistently, since the correct sales tax treatment can differ from job to job depending on these distinctions — confirm your specific treatment with the Texas Comptroller or your CPA.
OWNER'S TAKEAWAY: Don't assume every job's material sales tax treatment is the same. New construction and improvement-to-real-property contracts can be treated differently under Texas sales tax rules — track job type consistently so the right treatment gets applied every time. |

3. Why Clean Job-Level Records Matter for Both
Both franchise tax margin calculations and sales tax determinations depend on accurate, job-level financial records — revenue, cost of goods sold, and material purchases tracked by job. Construction cost accounting that already tracks job costs cleanly for profitability purposes is most of the way to having what's needed for accurate Texas tax reporting too.
Texas doesn't tax income, but it still expects your books to prove your numbers — for the franchise tax margin calculation and for sales tax on the materials in every job. Clean job-level records serve both. |
4. The Reports an Austin Contractor Needs
Pulling this together, here's what a Texas-based contractor should track:
Revenue and COGS by job — the basis for franchise tax margin calculation
Material purchases tracked by job type — supporting correct sales tax treatment
Job cost reports — actual cost versus bid, by job
Financial statements — P&L and balance sheet on a set schedule each month
With those in place, an Austin contractor tracks franchise tax and sales tax obligations correctly while keeping job costing accurate. That's construction accounting doing its job for Texas's distinctive tax structure.

Texas's tax structure for a construction business is more than "no income tax" — the franchise tax is a real, margin-based obligation, and sales tax treatment on materials depends on job type. Track revenue and cost of goods sold by job for franchise tax purposes, track material purchases by job type for sales tax, and confirm current thresholds and rules with the Texas Comptroller since both do change.
The Austin contractors who stay compliant aren't assuming Texas has no real tax obligations — they're the ones whose construction bookkeeping services are built for the state's actual structure.
