The window to amend\u00a0prior year\u00a0returns for the R&D tax credit is closing in 2026.\u00a0<\/p>\n\n\n\n

The July 6, 2026, deadline is not just a date on a calendar\u2014it’s the day the IRS stops allowing you to fix 2022-2024 tax mistakes. <\/p>\n\n\n\n

This is not new information. What\u2019s surprising is how many companies still haven\u2019t acted on it. <\/p>\n\n\n\n

The One Big Beautiful Bill Act didn\u2019t just change how R&D is treated going forward\u2014it created a one-time opportunity to revisit the past. <\/p>\n\n\n\n

Businesses that were required to capitalize R&D expenses from 2022 through 2024 now have a limited window to amend prior returns and recover those deductions. <\/p>\n\n\n\n

\n

That window closes on July 6, 2026.\u00a0<\/strong><\/p>\n<\/blockquote>\n\n\n\n

What changed\u2014and why timing now matters<\/strong> <\/h2>\n\n\n\n

For the past few years, Section 174 has created a disconnect for many businesses\u2014especially in software and product-driven companies. <\/p>\n\n\n\n

R&D costs that were once immediately deductible had to be capitalized and spread over multiple years. The results: higher taxable income, reduced near-term cash benefit, and confusion around how to plan to go forward. <\/p>\n\n\n\n

With the new law, domestic R&D expenses are back. More importantly, there\u2019s now a retroactive pathway<\/strong> to revisit those earlier years. <\/p>\n\n\n\n

But this isn\u2019t automatic. It requires a deliberate decision to amend prior returns\u2014and that decision sits inside a fixed timeline. <\/p>\n\n\n\n

Why most companies will miss this<\/strong> <\/h4>\n\n\n\n

Most companies do not miss out because they don\u2019t qualify. It\u2019s because they haven\u2019t decided. <\/p>\n\n\n\n
