Engineering and Architecture Tax Planning: QBI, Research and Contracts
By AE Tax Advisors · Published 2026-08-11 · Updated November 8, 2026.
Engineering and architecture practices should evaluate the tax treatment of actual services and project costs. Professional status alone does not establish a full QBI deduction or an eligible research credit.
Calculate QBI after the service classification
Engineering and architecture are excluded from the specified-service definition used by Section 199A. The deduction still depends on qualified income, the taxable-income limitation and, where applicable, W-2 wages and qualified property. Other activities within a firm may need separate review.
For a shareholder-employee, compensation must remain reasonable for the work performed. Model payroll and QBI together; an additional wage dollar does not necessarily create a net tax benefit.
Separate research deductions from research credits
Section 174A provides current deduction treatment for qualifying domestic research or experimental expenditures in tax years beginning after 2024, subject to applicable elections and rules. Foreign research and prior capitalized balances need separate treatment. A deduction under the research-cost rules does not automatically establish a Section 41 credit.
Document the research-credit requirements by project
Identify the business component, technical uncertainty, process of experimentation and qualifying activities. Routine design work or a challenging project is not enough by itself. Reconcile qualified expenses to payroll, supplies, contracts and accounting records.
Read the funded-research provisions
Review substantial rights in the research and whether payment depends on successful performance. The funded-research exclusion can apply if the firm lacks sufficient rights or does not bear the required economic risk. A fixed-price label alone does not resolve the question; examine the complete agreement and actual obligations.
Price retirement plans and exit structures separately
Obtain plan-administrator and actuarial projections covering owners and staff before relying on a contribution estimate. Evaluate funding commitments and related-employer rules. Also distinguish QBI eligibility from qualified-small-business-stock eligibility; the rules do not use identical exclusions.
Request a practice tax review with project contracts, payroll, research records and the current entity structure.
Frequently Asked Questions
Does an engineering license guarantee a research credit?
No. The project activities, expenses, contracts and other requirements determine eligibility.
Does a fixed-price contract automatically clear the funded-research rule?
No. Review payment risk, substantial rights and the complete agreement.
