The life sciences industry runs on innovation, and it isn’t just the science that keeps advancing. The regulatory environment, macroeconomic backdrop, and accounting standards are all evolving quickly.
For teams navigating that landscape, Deloitte recently released the 2026 Life Sciences Industry Accounting Guide, with interpretive guidance, illustrative examples, and the latest standard-setting, legislative, and rulemaking developments.
Read on for some of the key updates you should know.
Revenue arrangements continue to raise complex questions for life sciences entities, often requiring the application of significant judgment. This year’s Guide adds content reflecting both market developments and Securities and Exchange Commission (SEC) scrutiny.
As R&D grows more complex and innovation continues to be fueled by mergers and acquisitions, the related accounting requires careful consideration. The Guide offers updated content and clarifications around this issue.
This year’s Guide restructures its tax content around a new section consolidating provisions relevant to life sciences entities, anchored by the One Big Beautiful Bill Act signed into law on July 4, 2025.
IPOs remain a defining feature of the industry: Approximately 43% of all IPOs from 2020 through November 2025 were in the life sciences sector.1 The Guide offers timely insights for current and potential transactions.
The updated Guide also examines hot topics shaped by new standards and by significant developments affecting the industry.
