Construction and design firms face unique financial challenges—from “lumpy” revenue recognition to multi-state tax compliance. We help you utilize strategic accounting methods like the Completed Contract Method to defer income and maximize the newly increased 23% Qualified Business Income (QBI) deduction. We act as your project “back office,” allowing you to focus on the build.


Modern mandates, including the permanent provisions of the One Big Beautiful Bill Act (OBBBA), have created significant opportunities for firms in design and construction. BestFiler provides the technical framework to ensure these advantages are fully integrated into your financial strategy.

Construction and architecture firms require precise tracking of direct labor, materials, and subcontractor costs. We implement Work-in-Progress (WIP) and Percentage-of-Completion (PCM) accounting models to ensure your financial statements accurately reflect project progress.

Whether you are investing in a new fleet of machinery or advanced Building Information Modeling (BIM) software, BestFiler leverages the permanent reinstatement of 100% Bonus Depreciation. This allow firms to write off the full cost of qualified hardware and technical infrastructure in the year they are placed in service. We also coordinate, freeing up the essential cash flow needed to fund your next mobilization.
Our services are tailored to the specific operational and capital needs of your firm:









We provide a streamlined, digital-first workflow that integrates with your project management:
We analyze your contracts to determine if the Percentage-of-Completion or Completed Contract Method offers the best tax-timing advantage for your firm.
We track your high-value assets—from heavy machinery to workstations—and utilize accelerated depreciation to maximize current-year write-offs.
We provide dashboards that highlight key metrics like Overhead Ratios and Job Costing Accuracy, helping you make informed bidding and scaling decisions.
We maintain the technical narratives and financial records required to defend your project-based deductions and energy-efficient design credits.



Yes. While many professional services face income-based restrictions on this deduction, architects and engineers are specifically protected. This allows you to exclude up to 23% of your net business income from federal taxation, regardless of your total earnings.
For work performed within the United States, you can typically deduct 100% of your research and experimental costs in the year they happen. This includes time spent solving technical uncertainties or developing new building methods.
Architects and designers who create energy-efficient commercial buildings can often have the federal tax deduction "assigned" to them by government entities. This provides a direct tax benefit for your design work on interior lighting, HVAC, and building envelopes.
This method allows you to defer recognizing income and expenses until a project is actually finished. For firms with long build cycles, this can significantly improve cash flow by delaying the tax bill until the project has generated actual cash.
