Lease Accounting Issues That Trigger Audit Findings (and How To Avoid Them)

Lease accounting has come a long way since the Financial Accounting Standards Board (FASB) issued ASC 842. However, for many organizations, the journey is far from over. Keeping your spreadsheets accurate, complete, and audit-ready year after year is an entirely different challenge.

Whether you’re a Controller managing hundreds of real estate leases or a CFO overseeing a complex multi-entity portfolio, the pressure is real. Auditors are looking harder at lease accounting, and the stakes for getting it wrong are higher than most finance teams realize. For lessees navigating ongoing compliance, understanding where the most common lease accounting errors originate is the first step to staying ahead of them.

Why Lease Accounting Issues Are on the Rise

When the FASB introduced new lease accounting standards under Topic 842 (GAAP) and the IFRS Foundation finalized IFRS 16, they fundamentally changed how companies report their leasing activity. Now, years into implementation, the expectation from auditors is that everyone has their house in order. The problem? Many organizations are still struggling.

Here’s what you need to know:

• Audits are revealing more problems. The Public Company Accounting Oversight Board (PCAOB) anticipates that around 40% of audits reviewed will exhibit one or more deficiencies. This is up from 29% in 2020. Lease accounting consistently appears on the list of problem areas.
• Data centers and real estate are under strict scrutiny. At the 2025 AICPA & CIMA Conference on SEC and PCAOB Developments, Deloitte highlighted that ASC 842 requires the lessee to determine the lease commencement date and, if there is construction, whether the lessee should be considered the deemed owner of the asset during construction.
• ASC 842 issues are getting noticed. Auditors see these compliance issues. And when they surface, the consequences range from restatements and material weaknesses to reputational damage with investors and lenders.

The good news is that the most common lease accounting issues follow predictable patterns. With the right controls in place, they are entirely preventable. Below are the five most common lease accounting mistakes and how to avoid them.

Incomplete Lease Inventory and Embedded Leases

The first major mistake seems deceptively simple: businesses don’t actually know everything they’ve leased.

Under ASC 842, the definition of a “lease” is broad. A lease is any contract that conveys the right to control the use of an identified underlying asset for a period of time in exchange for consideration. That definition includes:

• Real estate
• Equipment lease agreements
• Service contracts
• IT outsourcing arrangements
• Logistics agreements
• Supplier contracts
• And more

Embedded leases are among the most frequently missed items in a lessee’s lease inventory. They arise when a contract grants the customer the right to control a specific underlying asset, such as a dedicated server, a piece of manufacturing equipment, or a warehouse. Often, the word “lease” never appears in the document.

To avoid serious audit errors, you need to identify every contract that qualifies as a lease under this broad definition. It might be particularly hard to find every lease if your organization has legacy lease arrangements that predate ASC 842 adoption or complex vendor relationships that bundle lease and non-lease components in the same contract.

You need a systematic contract review. Without such a review, lease data is incomplete, and the balance sheet understates both lease liabilities and right-of-use assets. Properly separating non-lease components, allocating consideration, and then capturing the lease data accurately in your records requires both rigorous process and the right tools.

Lease Classification Errors That Draw Auditor Attention

Finding every lease is only the beginning. You must also correctly classify your leases. And different accounting standards have different classifications. It’s no wonder why misclassifications are some of the most common lease accounting mistakes that auditors find.

Under ASC 842, a lessee classifies a lease as a finance lease if it meets any one of five criteria at lease commencement:

1. The underlying asset transfers to the lessee
2. The present value of lease payments represents substantially all of the asset’s fair value
3. The lease term covers the major part of the asset’s remaining economic life
4. A purchase option is reasonably certain to be exercised
5. The leased asset is specialized with no alternative use to the lessor

When none of those criteria are met, the lease is an operating lease.

Here’s the problem: lease classification requires judgment, which can be inconsistent. For example, two analysts looking at the same lease agreement might apply the 75% economic life threshold differently.

IFRS 16 takes a different approach. It eliminates the lessee’s distinction between operating leases and finance leases altogether, requiring all leases to be recognized on-balance sheet under a single model. That simplification removes one classification judgment for IFRS 16 preparers, but it introduces its own complexity in areas like lessor accounting, where IFRS 16 retains its own classification criteria.

Organizations reporting under both ASC 842 and IFRS 16 need to manage these differences carefully to avoid lease accounting mistakes in either framework.

The right accounting tool should support configurable lease classification logic that applies your organization’s accounting policies consistently across every lease in the portfolio, reducing the risk of inconsistent judgments and ensuring classifications are documented and defensible at audit time.

Discount Rate Miscalculations

The discount rate is one of the most technically sensitive inputs in lease accounting, and it’s one of the most common sources of ASC 842 compliance issues. Under both ASC 842 and IFRS 16, lessees must discount future lease payments to their present value to calculate the lease liability and the corresponding ROU asset.

The rate used for that calculation has an outsized effect on both balance sheet values, which is exactly why auditors scrutinize it closely.

ASC 842 allows lessees to use the rate implicit in the lease if it can be readily determined. In practice, lessors rarely disclose the implicit rate, so most lessees fall back on the incremental borrowing rate. This is the rate the lessee would pay to borrow funds on a collateralized basis over a similar lease term, for a similar amount, in a similar economic environment.

Several compounding factors make it difficult to get the discount rate correct:

• It takes expertise and information. You need someone on your team who is an expert in financial modeling, access to current market data, and documentation that supports the rate chosen.
• Many opportunities for audit red flags. Auditors look for stale discount rates, rates applied inconsistently across the portfolio, and rates that don’t reflect the correct lease term.
• You must reassess often. You need to run the numbers again anytime lease terms change, lease modifications occur, or certain practical expedient elections are revisited. A discount rate that was reasonable at original lease commencement may be materially wrong for a lease that has been extended or modified.
• It’s a lot to manage manually. If you manage hundreds or thousands of leases, maintaining discount rates across the entire portfolio is genuinely difficult without automation.

Private companies also have a practical expedient available under ASC 842 allowing the use of a risk-free rate as the discount rate for all leases, which simplifies the present value calculation but affects balance sheet values. Finance teams should weigh those trade-offs deliberately and document the election clearly.

Poor Lease Modification Tracking

Lease modifications are a fact of life for any organization with a significant lease portfolio. Each of these events can trigger a requirement under ASC 842 to remeasure the lease liability, update the right-of-use asset, and in some cases reassess lease classification from the effective date of the modification.

The problem is that lease modifications are easy to miss and even easier to mishandle. Here’s why:

• Informal agreements. A lessor and lessee may agree to change lease payments informally, through a side letter or email, without a formal contract amendment.
• Leaving accounting out. Renewal options may be exercised without notifying the accounting team.
• Variable payments change things. Variable lease payments may change based on index adjustments that trigger remeasurement obligations.
• Other transactions. Subleases and leaseback transactions introduce additional accounting complexity that requires careful analysis of who holds what rights and obligations.

When lease modifications are not properly tracked, the required journal entries for remeasurement don’t happen, lease data goes stale, and the financial statements reflect lease terms and payment amounts that no longer match reality.

Managing modifications in spreadsheets? This is a particularly significant lease accounting problem. Manual tracking is error-prone, version control is unreliable, and there’s no built-in trigger to prompt remeasurement when a contract event occurs. Auditors are trained to find discrepancies between contract reality and balance sheet values.

A complete modification tracking process should capture all key lease data events:

• Changes to lease terms
• Renewal options exercised
• Adjustments to lease commencement dates
• Expansions that add new underlying assets
• The creation of subleases or leaseback arrangements

Each event needs to be evaluated against the ASC 842 modification framework to determine whether it qualifies as a separate contract or requires remeasurement of the existing lease liability.

Inadequate Disclosures and Documentation

Even when a company has correctly identified its leases, classified them, applied the right discount rates, and tracked every modification, it can still receive an audit finding. Why? Because of inadequate disclosures.

ASC 842 includes extensive disclosure requirements designed to give financial statement users a complete picture of an organization’s leasing activity, assumptions, and risks.

Under Topic 842 and the related ASUs, lessees must disclose qualitative information about the nature of their leases, as well as quantitative data including:

• Weighted-average discount rates
• Remaining lease terms
• Maturity analyses of lease liabilities
• Lease expense breakdowns
• Short-term lease elections
• Cash flows associated with lease payments

For IFRS 16 reporters, the parallel IFRS 16 disclosure requirements are equally detailed. In some respects, it’s even more prescriptive about how leased asset information should be presented and how depreciation and amortization are disclosed.

A CPA reviewing the footnotes will quickly assess whether the right-of-use asset and lease liability figures are consistent, whether variable lease payment bases are explained, and whether the practical expedient elections applied are properly disclosed.

Common disclosure gaps include:

• Missing maturity schedules for operating leases and finance leases presented separately
• Incomplete descriptions of variable lease payment bases
• Failure to distinguish leased asset categories by classification
• Omitted short-term lease disclosures for portfolios that have elected the practical expedient under an applicable ASU

Each of these gaps signals to auditors that the underlying lease accounting processes may not be as robust as they appear.

How To Build Audit-Ready Lease Accounting Processes

The five issues above share a common root cause: relying on manual, fragmented processes. These tasks really require consistency, completeness, and real-time responsiveness. Building audit-ready lease accounting means building processes that address these failure points systematically.

Here’s what that looks like in practice:

• Centralize your lease data. Every lessee and lessor relationship, every operating lease and finance lease, every sublease, leaseback, and lease arrangement should live in a single system of record. A centralized lease management platform ensures all leased asset information is accessible, current, and traceable back to the underlying asset and contract.
• Automate embedded lease detection. Build a process for reviewing new contracts against ASC 842 and IFRS 16 criteria before they’re executed, so embedded leases are captured at inception. Lease accounting software with contract review workflows makes this systematic rather than dependent on individual judgment.
• Keep discount rates current. Establish a policy for how discount rates are set, by whom, and how often they’re reviewed. Apply FASB-compliant processes for updating rates when lease modifications occur or when lease commencement dates shift.
• Treat lease modifications as triggering events. Any change to a lease term, lease payment structure, renewal option, or underlying asset should immediately enter a defined accounting workflow. Subleases and leaseback transactions should be evaluated for separate accounting treatment under the applicable standard.
• Generate disclosures from source data. Use a system that produces ROU asset rollforwards, lease liability maturity schedules, and operating lease and finance lease expense schedules directly from the underlying lease data. The numbers tie automatically and amortization is always current.
• Maintain a complete audit trail. For every classification judgment, every discount rate selection, every present value calculation, and every journal entry, your system should capture who made the decision, when, and why. That documentation transforms a lease accounting process from reactive to genuinely audit-ready.
