Your Company Is Spending Millions on AI. Your Tax Department Is Probably Not in the Room.
AI spending is not automatically R&E or credit-eligible. Section 174A changed domestic R&E treatment for tax years beginning after December 31, 2024; foreign research and transition elections require separate analysis.
Editorial source review — November 1, 2026. This machine-generated article has been reviewed, but is not certified accurate. Source-backed corrections are incorporated where established. Other legal, survey and product claims may remain unverified; check applicable primary authorities before relying on a deadline or tax position.
Findings in the original version: current domestic five-year section 174 amortisation is wrong after OBBBA. The claimed credit range on total AI spending has no demonstrated qualified-cost/base calculation.
AI investment can create tax-classification, accounting-method and research-credit questions. Neither the label “AI” nor a large project budget determines the answer. Involve tax before contracts and development activities are finalised.
Domestic R&E changed after OBBBA
Section 174A generally allows a deduction for qualifying domestic research or experimental expenditures paid or incurred in tax years beginning after December 31, 2024, subject to applicable elections and transition rules. Presenting five-year domestic amortisation as the universal current rule is incorrect.
Foreign research remains subject to separate section 174 treatment, including the applicable 15-year amortisation rule. Identify where the activity is performed. Software development, purchased products, hosted services, implementation and employee training do not automatically have the same tax character.
Transition balances and elections matter
Section 174A's statutory notes contain options for certain previously capitalised domestic expenditures and eligible small businesses. Eligibility, election deadlines, method changes and amended returns require individual review. Do not assume every taxpayer can deduct all historic balances immediately or make a late election without relief.
Research credits require a separate qualification analysis
A deduction under section 174A does not establish a section 41 credit. Test qualified activities, eligible costs, exclusions and the relevant credit method. The regular credit's 20% and alternative simplified credit's 14% are not flat percentages applied to all AI spending.
A $50 million AI budget therefore does not support a $3–10 million credit estimate without the actual qualified-expenditure and base calculations. Retain contemporaneous technical and cost documentation rather than projecting a credit from the project label.
Provision effects depend on book and tax treatment
Compare the actual book carrying amount with tax basis. If a cost is expensed for book but capitalised for tax, the remaining tax deduction generally gives rise to a deductible temporary difference, subject to deferred-tax recognition and realisability requirements—not automatically a DTL. Other book/tax treatment combinations can produce different results.
Evaluate credit recognition and uncertain positions separately. A webcast or vendor claim is not proof that a company's activity qualifies.
