There is no new ASC 842 rule in 2026. The most recent amendment to the leases standard is still ASU 2023-01 (common control arrangements, March 2023). In November 2025 the FASB completed its post-implementation review of ASC 842, concluded the standard met its objectives, and identified no matters that warrant new standard setting. So the work in 2026 is not learning a new rule, it is getting the recurring judgments right.
Last updated July 2026.
Search interest in an "ASC 842 update" keeps climbing, which is understandable: the standard was a heavy lift, and teams want to know whether the ground is shifting under them again. The honest answer is reassuring. The rule is stable. What is not stable is how consistently companies apply it, and that is where auditors and the SEC are spending their attention.
Is there a new ASC 842 update in 2026?
No. The FASB has not issued any Accounting Standards Update that amends Topic 842 in 2024, 2025, or 2026. The FASB's technical agenda, revised July 1, 2026, contains no leases project. The 2026 updates the board has issued so far address paid-in-kind preferred dividends and environmental credits, not leases. If you see a claim that a 2025 or 2026 ASU changed lease accounting, it is a mix-up with an unrelated standard; none of the recent updates touch leases.
What is the most recent change to ASC 842?
The most recent amendment to ASC 842 is ASU 2023-01, Leases (Topic 842): Common Control Arrangements, issued in March 2023 and effective for fiscal years beginning after December 15, 2023. It gives private companies and not-for-profits a practical expedient to use the written terms of a common-control arrangement to decide whether a lease exists and how to classify it, and it requires common-control leasehold improvements to be amortized over their useful life to the common-control group rather than the lease term. Before that, ASU 2021-09 let private-company lessees elect the risk-free discount rate by class of underlying asset instead of all or nothing. Both are still the current guidance.
What did FASB's post-implementation review conclude?
In November 2025 the FASB delivered its post-implementation review of Topic 842. The review found the standard met its general objectives of putting leases on the balance sheet and improving transparency, but that lessee implementation and ongoing costs were, in the board's words, significantly higher than expected at issuance. Critically, FASB staff identified no matters warranting immediate standard-setting action. In plain terms: the rule works, it was expensive to adopt, and it is not going to change soon. Teams should plan their 2026 close on the assumption that ASC 842 stays exactly as it is.
What still trips teams up under ASC 842?
Because the rule is settled, the risk has moved from adoption to steady-state application. These are the areas that produce the most audit adjustments and SEC comments.
| Issue | Where teams go wrong |
|---|---|
| Embedded leases | Missing leases hidden inside service, supply, or logistics contracts, which leaves the lease population incomplete |
| Discount rate | Unsupported incremental borrowing rates, or over-reliance on a single portfolio rate; private companies mishandling the risk-free-rate-by-asset-class election |
| Classification | Misapplying the five finance-versus-operating criteria |
| Modifications vs remeasurement | Confusing a lease modification with a remeasurement trigger such as a change in term or a reassessed renewal option |
| Common-control leases | Not applying ASU 2023-01's written-terms expedient and leasehold-improvement amortization rule |
| Short-term and renewal judgments | Mis-scoping the 12-month exemption and the reasonably-certain renewal assessment that changes the term |
Most of these failures start upstream, in the lease data. If the abstracted term, options, and payment schedule are wrong, the accounting is wrong no matter how good the software is. That is why a clean abstraction is the foundation of a defensible ASC 842 position. Our guide on how to prepare lease data for ASC 842 walks through the exact fields the calculation needs, and the piece on how to determine lease term under ASC 842 covers the renewal-option judgment that drives the whole schedule.
Is ASC 842 still in effect for private companies?
Yes. ASC 842 has been mandatory for private companies for fiscal years beginning after December 15, 2021, which for a calendar-year company meant the year starting January 1, 2022. It is fully adopted now, and the one-time transition practical expedients were elected at adoption, so there is no fresh transition relief for existing companies in 2026. New entities and first-time filers still apply the standard on adoption using the transition guidance in place.
What are auditors and the SEC focused on for leases?
According to Deloitte's SEC comment-letter analysis, the SEC staff has issued more comments on the application of ASC 842 recently than in prior years. The comments cluster on discount-rate judgments, distinguishing lease from non-lease components, modifications versus terminations, sale-leaseback accounting, right-of-use asset impairment, and the required disclosures. A recurring theme is that boilerplate disclosure that just restates the definition of the incremental borrowing rate does not satisfy the requirement. The takeaway for 2026 is documentation: be able to show the support behind every judgment.
Does the 2026 status differ for GASB 87 or IFRS 16?
Yes, and it is worth keeping straight. ASC 842 governs US GAAP lessees and lessors. Governments follow GASB 87, which took effect for fiscal years beginning after June 15, 2021 and uses a single lease model rather than the operating-versus-finance split. Companies reporting under IFRS use IFRS 16, which puts almost all leases on the balance sheet as finance-style leases with no operating classification for lessees. None of the three changed in 2026. If you operate across frameworks, the classification and expense pattern differ even when the underlying lease is identical, so abstract once and map the same terms into each model. Our comparison of GASB 87 versus ASC 842 lays out where a government's treatment diverges from a company's.
The bottom line for 2026
No new standard, no looming rewrite, and a post-implementation review that closed the book. The compliance risk under ASC 842 in 2026 is execution: complete lease populations, supportable discount rates, correct term judgments, and disclosures that show your work. It starts with accurate lease data. The lease invoices behind those schedules still have to be recorded and paid on time each month, which is why many teams pair their lease accounting with a way to automate the accounts payable behind them.
