Why Engineering Firms in Dallas Need a CPA Who Understands Project-Based Work
Engineering firms face tax situations that most general-practice CPAs handle poorly or miss entirely. Your revenue arrives in irregular project cycles, your most valuable asset is technical labor, and some of your most significant tax credits require documentation that has to be built throughout the year, not reconstructed at filing time. A CPA who doesn’t understand engineering work will prepare a compliant return but leave tens of thousands of dollars on the table.
At AG Freideman, we work with engineering firm owners across the Dallas-Fort Worth area who need more than basic tax filing. Al Freideman, a licensed CPA with over 30 years of experience, handles every engineering client personally. That means one person who understands your project structures, your labor mix, and your contract types, year after year. No hand-offs to junior staff who have to relearn your business every filing season.
R&D Tax Credits: The Biggest Opportunity Most Engineering Firms Underutilize
The federal Research and Development Tax Credit under IRC Section 41 was designed for exactly the kind of work engineering firms do every day. If your team designs, tests, improves, or develops products, processes, or systems that involve technical uncertainty, those activities likely qualify. Yet many engineering firm owners assume the R&D credit is only for pharmaceutical companies or software startups.
For 2026, qualifying small businesses (under $5 million in gross receipts) can apply up to $500,000 of the R&D credit against payroll taxes annually, a provision made permanent by the PATH Act. That is real cash flow, not just a future tax offset. Qualifying activities for engineering firms typically include:
- Developing new structural, mechanical, or electrical designs that require iterative analysis or testing
- Creating prototypes or models to evaluate performance before final production
- Improving existing processes or systems where the outcome is not certain at the outset
- Environmental and energy compliance engineering that involves technical problem-solving beyond standard application of known methods
The key requirement is “technological uncertainty,” which the IRS defines as uncertainty about capability, method, or design at the start of the activity. Most engineering work meets this threshold. We help our clients document qualifying activities contemporaneously so the credit stands up to IRS scrutiny, not pieced together after the fact when records are incomplete.
Section 179D Energy-Efficient Commercial Building Deductions for Engineers
Engineers who design energy-efficient commercial buildings or government buildings can claim the Section 179D deduction, and the Inflation Reduction Act significantly expanded this benefit starting in 2023. For tax year 2026, the deduction ranges from $0.50 to $5.00 per square foot depending on the level of energy reduction achieved compared to ASHRAE Reference Standard 90.1.
Here is what many engineering firms miss: when you design an energy-efficient system for a government-owned building (schools, municipal facilities, public universities), the building owner cannot use the 179D deduction because government entities do not pay federal income tax. The IRS allows the deduction to be allocated to the designer of record, which is often your engineering firm. This pass-through provision means your firm can claim deductions on projects where you were not even the building owner.
Properly claiming 179D requires a qualified third-party energy study and certification. We coordinate with energy modeling professionals and ensure the deduction is correctly calculated and documented on your return. For Dallas-area engineering firms working on municipal, ISD, or state university projects, this deduction can be substantial.
Government Contract Accounting and Audit Readiness
Engineering firms that hold federal, state, or municipal contracts face accounting requirements that go well beyond standard GAAP. Federal contracts governed by the Federal Acquisition Regulation (FAR) require cost accounting that separates direct costs, indirect costs, and unallowable expenses with precision. If your books are not structured for this from the start, you risk disallowed costs, contract disputes, or failed audits by agencies like DCAA (Defense Contract Audit Agency).
We set up your chart of accounts and bookkeeping processes to support contract-compliant reporting from day one. This includes tracking labor by project, segregating unallowable costs (entertainment, certain interest expenses, lobbying), and maintaining indirect cost rate calculations that hold up under government review. Our monthly bookkeeping packages, which run $300 to $600 per month depending on complexity, include the bank reconciliation and project-level tracking that government contractors need.
Per-Project Accounting: Why Your Books Need to Match How You Actually Work
Engineering firms earn revenue project by project, but many use a single-bucket accounting approach that treats all income and expenses as one pool. This creates two problems: you cannot determine which projects are actually profitable, and you risk misreporting income under the percentage-of-completion method required by the IRS for certain long-term contracts.
Under IRC Section 460, contracts that span more than one tax year and exceed $30 million generally require the percentage-of-completion method. Even for contracts below that threshold, choosing the right accounting method (completed contract vs. percentage of completion) has significant tax timing implications. We evaluate each client’s contract portfolio and select the method that provides the best legitimate tax deferral while maintaining compliance.
Our bookkeeping setup includes project-level cost tracking in QuickBooks, so you can see profitability by engagement and we can prepare your return with accurate project-by-project data.
Common Tax Mistakes We Fix for Engineering Firms
After 30 years of working with business owners across multiple industries, Al Freideman has seen recurring mistakes that cost engineering firms real money. Here are the ones we correct most often:
- Failing to claim the R&D credit entirely. Many CPAs never ask whether your engineering work involves qualifying research activities. We review your project types during onboarding and identify credits going back up to three amended years.
- Misclassifying engineers as independent contractors. The IRS and Texas Workforce Commission scrutinize this heavily. Misclassification triggers back payroll taxes, penalties, and interest. We review your worker classifications and help you structure compliant arrangements.
- Ignoring the Section 199A qualified business income deduction limits. For S-Corp and partnership engineering firms, the QBI deduction phases out above $191,950 (single) and $383,900 (married filing jointly) for 2026 because engineering is a “specified service trade or business.” Proper planning around owner compensation and entity structure can preserve part or all of this 20% deduction.
- Not making timely S-Corp elections. Many engineering LLCs operate as default partnerships or sole proprietorships and overpay self-employment tax by $10,000 or more annually. We evaluate whether an S-Corp election makes sense and file Form 2553 when it does.
- Poor documentation for vehicle and travel expenses on job sites. Engineers who travel to project sites, client offices, or field locations often deduct mileage or vehicle costs without IRS-compliant logs. We set up tracking systems that hold up in an audit.

Frequently Asked Questions from Engineering Firm Owners
Does my engineering firm qualify for the R&D tax credit?
Most engineering firms qualify. If your team designs, tests, or develops products, processes, or systems where the outcome involves technical uncertainty at the outset, those activities meet the IRS Section 41 criteria. Civil, mechanical, electrical, and environmental engineering work all commonly qualifies. We evaluate your specific projects during your free consultation.
How does the Section 179D deduction work for engineers who design government buildings?
When you design energy-efficient systems for government-owned buildings, the 179D deduction passes through to you as the designer of record because the government entity cannot use the tax benefit. The deduction ranges from $0.50 to $5.00 per square foot for 2026 and requires a third-party energy certification. We coordinate the certification process and claim the deduction on your return.
Should my engineering LLC elect S-Corp status?
In many cases, yes. Engineering firm owners with net income above roughly $60,000 to $80,000 annually often save $10,000 or more per year in self-employment taxes by electing S-Corp status. However, the election also triggers payroll requirements and affects your Section 199A deduction. We run the numbers for your specific situation before recommending a change.
What accounting method should my engineering firm use for long-term contracts?
The IRS requires percentage-of-completion for certain long-term contracts exceeding $30 million under IRC Section 460. For smaller contracts, you may be able to use the completed-contract method, which defers income recognition until the project is finished. The right choice depends on your contract sizes, project timelines, and cash flow needs. We evaluate your portfolio and select the method that provides the best tax outcome.
Do you work with engineering firms outside of Dallas?
Yes. While our office is located on Preston Road in North Dallas and we serve engineering firms throughout Plano, Frisco, Allen, McKinney, and Richardson, we also work with clients virtually across Texas and nationwide. Al handles every client personally whether meetings are in-person or remote.
