Corporate Returns for Construction and Contractors in Austin

Which corporate return you file depends on how the contracting business is organized, and for an Austin contractor the federal choice is the whole income-tax story, because Texas imposes no corporate or personal income tax to add a second return on top. The most common setup is the S corporation, which files Form 1120-S federally. The S corporation does not pay federal income tax itself. Instead it reports the business profit and passes it out to the owners on Schedule K-1, and each owner picks up the profit on a personal 1040. A contractor organized as a regular C corporation files Form 1120 and pays the federal corporate income tax of 21 percent at the entity level, then any dividends are taxed again to the owner, which is the double taxation that pushes most contractors toward the S election in the first place.

For construction, the return type is only half the story, because the accounting method matters more than the entity form. Long-term contracts, meaning construction contracts that are not finished in the same tax year they begin, must generally be reported under the percentage-of-completion method of Section 460. That means the return recognizes income as the job progresses, measured by costs incurred against the total estimated cost, rather than when the customer is billed or pays. A contractor who reports revenue on a simple cash basis produces a return that does not match the method the law requires, and the IRS can adjust it, which is why the corporate return has to be built off reliable job cost rather than the bank statement.

Here is how it comes together in numbers. Suppose your S corporation has one main job, a 1,200,000 dollar contract that is 50 percent complete by cost at year-end and carries a 300,000 dollar estimated profit. The 1120-S recognizes 150,000 dollars of that profit this year under percentage-of-completion and passes it to the owners on their K-1s, even if progress billings have brought in less cash so far. Unlike a California S corporation, which owes the state a 1.5 percent tax on that net income, a Texas S corporation owes no state income tax, so the profit is taxed only once, federally, on the owners’ returns. The Texas franchise report is separate and owes nothing below the revenue threshold.

We prepare the federal return built from the same job cost we maintain through bookkeeping, so the entity return reconciles to the WIP schedule your bonding company already relies on and the method is defensible if the IRS asks how the income was figured. One practical point contractors miss is that the entity return and the personal return are joined at the K-1, so an error on the 1120-S does not stay contained, it flows straight onto every owner’s 1040 and changes the personal tax and the estimated payments. That is why we close the entity return and the owner returns as one connected job rather than two separate filings prepared in isolation, and why the job cost feeding the 1120-S has to be right before anything else is calculated.

Percentage-of-completion is the accounting method most long-term construction contracts must use on the corporate return, and it governs how much of each job’s profit shows up in each tax year, though in Texas the income-tax consequence is entirely federal because the state taxes neither the corporation nor its owners on income. Under Section 460, a contractor recognizes contract income in proportion to how far along the job is, and the measure of progress is almost always the cost-to-cost method, which compares costs incurred to date against the total estimated cost of the contract. If a job has incurred 40 percent of its expected total cost, then 40 percent of the contract revenue and its related profit are recognized this year, whether or not the owner has been billed that much. The method exists so that a contractor cannot defer years of profit simply by delaying the final invoice.

The mechanics depend entirely on reliable cost data, which is why job costing is the foundation under the whole return. Consider a 2,000,000 dollar contract with a total estimated cost of 1,500,000 dollars, so an expected profit of 500,000 dollars. By December 31 the job has incurred 900,000 dollars of cost, which is 60 percent of the estimated total. The return therefore recognizes 60 percent of the revenue, 1,200,000 dollars, and 60 percent of the profit, 300,000 dollars, for the year. If your cost estimate was off and the job actually costs more, the percentage complete was overstated and too much profit was pulled forward, which the look-back method later corrects with interest. That sensitivity to the estimate is why a contractor cannot run percentage-of-completion off guesswork, because the tax follows the cost figures precisely.

Because the method is so sensitive to the estimate, the quality of the estimate itself becomes a tax matter, not just a project-management one. A contractor who pads the estimated total cost to look conservative will understate the percentage complete and defer profit that the IRS can pull back, while one who lowballs the estimate pulls profit forward and pays tax early. We review the estimated cost to complete on each open job at year-end against the actual field progress, so the percentage that drives the return reflects reality. That single review is often what separates a clean contract-method return from one that the look-back method later corrects with a bill for interest.

There are limited escapes from the method. A small contractor whose average annual gross receipts over the prior three years fall under the inflation-adjusted threshold can use the completed-contract method for contracts expected to finish within two years, and home construction contracts get their own exemption. But most commercial Austin contractors above that receipts level are locked into percentage-of-completion for regular tax. Because Texas has no income tax, the method choice does not carry a state income-tax effect, though for a contractor over the franchise-tax threshold, how and when revenue is recognized can shift the margin computation. We compute the percentage complete from current job cost, recognize the correct income on the federal return, and keep the supporting WIP schedule through tax strategy consulting, so the profit lands in the right year rather than being pulled forward or pushed back by sloppy cost tracking.

A reasonable salary on a construction S corporation return is the wage a contractor would have to pay someone else to do the work the owner actually performs, and setting it correctly is one of the most scrutinized figures on the whole return, made even more central in Texas because there is no state income tax to complicate the analysis, leaving it a pure federal payroll-tax question. The reason it matters so much is the tax difference between salary and distribution. Wages you pay yourself carry payroll tax, the combined Social Security and Medicare of 15.3 percent split between the company and you, while distributions of the remaining profit pass through free of that payroll tax. That gap creates an obvious temptation to pay a tiny salary and take everything else as distributions, and the IRS knows it, so a low officer salary paired with large distributions is one of the most common triggers for an S corporation audit.

The salary has to reflect what the role genuinely commands in the market. A working general contractor who runs jobs, hires subs, manages the crew, and handles bidding is doing skilled, well-paid work, so a token salary is indefensible. Suppose your S corporation nets 260,000 dollars before your compensation. Paying yourself a reasonable 100,000 dollar salary for a hands-on contractor, reported on a W-2, leaves 160,000 dollars to pass through as profit that avoids self-employment tax. That is legitimate tax planning. Paying yourself 30,000 dollars and taking 230,000 dollars as distributions is not, because no one would hire a contractor of your capability for 30,000 dollars, and if the IRS reclassifies the shortfall as wages you owe back payroll tax on the difference plus penalties and interest.

On the return itself, the salary appears as officer compensation, a deduction that reduces the pass-through profit, and it has to match the wages reported on your W-2 and the quarterly payroll filings. A mismatch between the officer compensation on the 1120-S and the payroll returns is its own red flag. We set the salary against real market data for a contractor doing your specific work, document the reasoning so it can be defended, and reconcile the officer compensation on the return to the payroll filings through payroll compliance. The goal is a number that captures the legitimate self-employment tax savings of the S election while being high enough that it survives the reasonable-compensation test.

The Texas advantage is that the salary figure moves only the federal payroll tax, not a state income tax, so the analysis is cleaner than in a state like California where the same salary also changes a 1.5 percent state entity tax. There is no second jurisdiction pulling the number in a different direction. We set the salary once, against market data for your trade and role, and let it flow correctly through the federal payroll filings and the federal 1120-S officer compensation line, so a single defensible number carries cleanly across both filings instead of drifting between them, and we revisit it each year because a figure that was reasonable when the business was smaller can drift out of line as the work and the owner’s role grow.

Most Austin construction contractors file a Texas franchise tax report with their corporate return but owe nothing on it, and understanding exactly where the tax starts is one of the first things a construction accountant clarifies, because the franchise tax is the only state-level tax on the entity, since Texas has no corporate or personal income tax. The franchise tax, sometimes called the margin tax, applies to most business entities doing business in the state, including LLCs, corporations, and limited partnerships. The key number is the no-tax-due threshold. When your total revenue falls at or below roughly 2.47 million dollars, you owe no franchise tax, and in recent years the state has moved toward not even requiring a report from entities below the threshold, though many still file to keep their status current. So a large share of Austin contractors are in the report-but-owe-nothing zone, which is a very different starting point from a contractor in a state that taxes corporate income from the first dollar.

Once revenue climbs above the threshold, the franchise tax is computed on your taxable margin, not on gross revenue, which is where the corporate return preparation adds value. Margin is generally the lowest of a few calculations, total revenue minus cost of goods sold, total revenue minus compensation, total revenue times 70 percent, or total revenue minus a standard fixed percentage. For a contractor, the cost of goods sold deduction is often the most favorable because construction labor and materials can qualify, and Texas has specific rules allowing contractors to include certain construction costs in COGS. Choosing the right margin calculation can meaningfully lower the tax, so the return is not a mechanical exercise but a choice among methods.

Here is a worked example. Suppose your construction business does 4,000,000 dollars in total revenue, above the threshold, with 2,600,000 dollars of qualifying cost of goods sold. Your margin under the COGS method is 1,400,000 dollars. The franchise tax rate for most entities is 0.75 percent, though a lower 0.375 percent rate applies to qualifying wholesalers and retailers, which most contractors are not. At 0.75 percent on a 1,400,000 dollar margin, the franchise tax is about 10,500 dollars. Had you used the 70 percent of revenue method instead, your margin would be 2,800,000 dollars and the tax about 21,000 dollars, so the COGS calculation saves roughly 10,500 dollars in this case. That is the kind of difference the right method makes on the return, and it is why the margin computation deserves real attention rather than a default election.

We handle the franchise tax through tax strategy consulting and the return preparation, testing each margin method against your actual numbers and making sure your construction costs are captured in COGS where the rules allow. The Texas Comptroller cost of goods sold guidance lays out which construction costs qualify. The practical point is that the franchise tax is not something to fear at the small end, where most Austin contractors owe nothing, but once the boom pushes revenue past the threshold it becomes a real number on the return that rewards careful margin planning, so we watch the revenue trend and prepare for the crossover before it arrives rather than after.

Equipment depreciation on an Austin contractor’s corporate return carries only one set of numbers, the federal set, because Texas has no corporate or personal income tax to decouple from the federal rules, which is a real simplification compared with a state like California that forces a separate state depreciation schedule. On the federal 1120-S or 1120, a contractor buying heavy equipment has two powerful tools. One hundred percent bonus depreciation is permanent again for qualifying property placed in service after early 2025 under Section 168(k), letting you deduct the entire cost of qualifying equipment in the year it goes into service. Section 179 expensing runs alongside it with a 2026 federal limit of 2.5 million dollars and a phaseout that begins around 4.09 million dollars of purchases. So on the federal return, a new 200,000 dollar excavator can often be written off in full the year you put it to work, a large deduction that flows through to the owners.

Where a California contractor would then have to add most of that deduction back for state purposes and track a parallel state basis for years, a Texas contractor does not, because there is no state income tax to require it. The same 200,000 dollar excavator fully deducted on the federal return simply reduces the profit passing to the owners, with no state addback and no separate schedule to maintain. That means the full federal write-off is the entire income-tax benefit, and the owner’s tax result is cleaner and easier to project. The one place equipment interacts with a Texas tax is the franchise tax, where the cost of equipment and materials can feed the cost-of-goods-sold margin for a contractor over the 2.47 million dollar threshold, so we coordinate the equipment treatment with the margin computation for larger contractors.

There is one construction-specific item the corporate return has to handle regardless of the state, the look-back method on completed long-term contracts. When a job reported under percentage-of-completion finally finishes, the original cost estimates that drove the income recognition almost never matched the actual results, so in hindsight too much or too little profit was recognized in the earlier years. The look-back method recalculates the tax as if the actual figures had been known, and computes interest owed to or from the IRS on the difference, reported on Form 8697. It is a required filing on completed long-term contracts above the small-contractor thresholds, not an optional step, and skipping it leaves the return incomplete.

We build the federal depreciation, record the equipment where it feeds the franchise margin for a larger contractor, file the look-back where it applies, and coordinate the equipment purchase timing so the deductions land in the best year through tax strategy consulting. Because there is no parallel Texas basis to maintain, placing a major purchase in a high-income year captures the full benefit without the multi-year state catch-up a California contractor has to track. The practical result is that equipment planning for an Austin contractor is about federal timing and, for larger firms, the franchise margin, rather than the two-system reconciliation that burdens contractors in states that refuse to follow the federal depreciation rules.
