July 6, 2026 is the deadline to elect and claim immediate expensing of domestic research and development expenditures for 2022–2024 by filing amended returns. Beginning in 2022, Section 174 required R&D costs to be capitalized and amortized over five years, significantly reducing near-term tax benefits, but the One Big Beautiful Bill Act (OBBBA), enacted July 4, 2025, restores immediate expensing under Section 174A and allows retroactive application through amended returns, potentially generating refunds or increasing net operating losses, while failure to act leaves those costs subject to less favorable amortization rules. https://ics-tax.com/news/july-6-2026-deadline-key-opportunity-for-rd-deductions-and-credits/
