What is lease accounting?
Lease accounting is how organizations record lease transactions in their financial statements. Every time a company rents office space, leases a fleet of vehicles, or signs an agreement for equipment — that lease creates financial obligations that must be measured, tracked, and reported.
Under current accounting standards, lessees must recognize most leases on the balance sheet by recording a right-of-use (ROU) asset and a corresponding lease liability. This means lease obligations are no longer hidden in footnotes — they appear directly in the financial statements where investors, creditors, and auditors can see them.
The practice encompasses the full lease lifecycle: identifying contracts that contain leases, extracting relevant terms, classifying leases, calculating present values, generating journal entries, processing modifications, and producing the disclosures required by each standard.
Why lease accounting changed
Before the current standards took effect, organizations could keep operating leases entirely off the balance sheet. A company with $2 billion in lease commitments could report them only in footnote disclosures — invisible in the primary financial statements.
This created a transparency problem. Investors and analysts had to manually adjust financial statements to account for operating lease obligations. Two companies with identical operations could look dramatically different depending on whether they bought or leased their assets.
The response came in three waves: IFRS 16 (effective January 2019 for international reporters), ASC 842 (phased in between 2019 and 2022 for US GAAP entities), and GASB 87 (effective for government fiscal years beginning after June 2021). Each standard took a slightly different approach, but all shared the same core principle: leases belong on the balance sheet.
The five lease accounting standards
Five standards now govern lease accounting worldwide. Which one applies depends on your reporting framework and jurisdiction. Organizations reporting under multiple frameworks — multinational corporations, accounting firms serving diverse clients, government contractors — may need to apply several simultaneously.
| Standard | Framework | Effective | Lessee model |
|---|---|---|---|
| ASC 842 | US GAAP | 2019 / 2022 | Dual model (operating + finance) |
| IFRS 16 | International | Jan 2019 | Single model (all finance-like) |
| GASB 87 | US Government | Jun 2021 | Single model (straight-line interest) |
| GASB 96 | US Government | Jun 2022 | Single model (IT subscriptions) |
| FRS 102 | UK / Ireland | Jan 2026 | Dual model (aligned with IFRS 16) |
ASC 842 — US GAAP
ASC 842 is the lease accounting standard for entities reporting under US Generally Accepted Accounting Principles. Issued by FASB, it replaced ASC 840 and introduced the requirement to recognize virtually all leases on the balance sheet.
ASC 842 uses a dual classification model. Lessees classify each lease as either an operating lease or a finance lease based on five criteria. Both types appear on the balance sheet, but the expense recognition pattern differs:
- Operating leases — single straight-line lease expense each period
- Finance leases — separate depreciation (straight-line) and interest expense (front-loaded)
ASC 842 became effective for public companies in 2019 and private companies in 2022. All US GAAP entities must now be fully compliant. See our full ASC 842 implementation guide for a step-by-step approach.
IFRS 16 — International
IFRS 16 is the international lease accounting standard issued by the IASB. Unlike ASC 842's dual model, IFRS 16 uses a single lessee model — all leases are accounted for similarly to finance leases under ASC 842, with separate depreciation and interest charges.
This single-model approach means IFRS reporters recognize front-loaded expense on all leases, which can produce materially different income statement results compared to ASC 842 operating lease treatment. Organizations reporting under both standards need parallel calculations from the same lease data.
IFRS 16 provides two exemptions: a short-term lease exemption (12 months or less) and a low-value asset exemption (generally under $5,000). See our IFRS 16 transition guide.
GASB 87 — Government leases
GASB 87 applies to state and local government entities. It uses a single model where lessees recognize a lease asset and a lease liability, with interest allocated on a straight-line basis rather than the effective interest method used by ASC 842 and IFRS 16.
GASB 87 applies to nonfinancial assets only — real estate, equipment, vehicles. Intangible assets like software subscriptions fall under GASB 96 instead. Government entities with fiscal funding clauses must evaluate whether those clauses affect the lease term. See our GASB 87 implementation guide.
GASB 96 — Subscription-based IT arrangements
GASB 96 addresses subscription-based IT arrangements (SBITAs) — government contracts for cloud software, SaaS platforms, and IT services. It follows a recognition model similar to GASB 87: governments recognize a subscription asset and a corresponding subscription liability.
As government IT spending increasingly shifts from purchased software to subscription services, GASB 96 ensures these arrangements receive balance sheet treatment proportional to their financial significance.
FRS 102 — UK and Ireland
FRS 102 is being updated to align with IFRS 16 principles, effective January 2026. UK and Irish entities currently using the dual model (operating/finance) under old FRS 102 will transition to a recognition model that requires balance sheet recognition of most leases.
Arvexi supports FRS 102 alongside ASC 842, IFRS 16, GASB 87, and GASB 96 — all from a single lease data source. Multi-standard compliance eliminates the need for separate tools or parallel data entry.
Key concepts in lease accounting
Right-of-use asset
The right-of-use (ROU) asset represents your right to use the leased asset for the lease term. It is recognized at the commencement date and calculated as:
ROU Asset = Lease Liability + Initial Direct Costs + Prepaid Payments − Lease Incentives
The ROU asset is subsequently depreciated (finance leases) or amortized as part of the single lease expense (operating leases) over the lease term.
Lease liability
The lease liability represents the obligation to make future lease payments. It is measured as the present value of remaining lease payments, discounted at the discount rate (either the rate implicit in the lease or the lessee's incremental borrowing rate).
Amortization schedule
The amortization schedule is the period-by-period breakdown of lease payments into interest and principal components, along with the ROU asset amortization. This schedule drives the journal entries posted each reporting period. For a 10-year lease with monthly payments, that is 120 rows of calculations — and every modification requires recalculating the remaining schedule.
Discount rate
The discount rate determines the present value of lease payments and directly affects the size of the liability and asset on your balance sheet. ASC 842 prescribes a hierarchy: the rate implicit in the lease (rarely determinable by lessees), then the incremental borrowing rate, with a risk-free rate option available to private companies.
Lease modifications
A lease modification is any change to the terms of a lease — rent adjustments, term extensions, scope reductions. Each modification requires remeasurement of the lease liability using a current discount rate and a corresponding adjustment to the ROU asset. For active real estate portfolios, modifications are frequent and compound the accounting complexity.
The lease accounting lifecycle
Lease accounting is not a one-time event — it is a continuous process that follows the lease from inception to termination:
- Identification — determine which contracts contain a lease, including embedded leases within service contracts
- Data extraction — extract key terms from lease documents: dates, payments, escalations, options, incentives. AI-powered extraction eliminates the manual bottleneck
- Classification — apply the lease classification test (ASC 842) or determine the appropriate model under IFRS 16 / GASB 87
- Initial measurement — calculate the lease liability and ROU asset at commencement
- Ongoing measurement — generate journal entries each period from the amortization schedule
- Modifications — remeasure when lease terms change
- Disclosure — produce the quantitative and qualitative disclosures required by each standard
- Audit — provide auditors with complete audit trails from source document to journal entry
Operating leases vs finance leases
Under ASC 842, the classification test determines whether a lease is operating or finance. This distinction affects how expense flows through the income statement:
| Dimension | Operating lease | Finance lease |
|---|---|---|
| Balance sheet | ROU asset + lease liability | ROU asset + lease liability |
| Expense pattern | Single straight-line lease expense | Depreciation + interest (front-loaded) |
| Income statement | Operating expense (single line) | Depreciation + interest expense (two lines) |
| Cash flow statement | Operating activities | Financing (principal) + operating (interest) |
| Total expense | Same over lease term | Same over lease term |
Under IFRS 16, there is no classification test for lessees — all leases use the finance-like model with separate depreciation and interest. Under GASB 87, all leases use a single model with straight-line interest allocation.
Common lease accounting challenges
1. Finding all your leases
The most common audit finding is an incomplete lease inventory. Leases hide in procurement contracts, IT agreements, logistics arrangements, and facility management agreements as embedded leases. Organizations that survey only their real estate and fleet departments typically miss 10-20% of their total lease population.
2. Extracting data from documents
Every lease calculation starts with data extracted from the original document. For a single lease, an analyst needs 30-60 minutes to read and abstract all relevant terms. For a portfolio of 500 leases, that is 250-500 hours before any calculations begin. AI-powered extraction compresses this from months to days.
3. Handling modifications at scale
Active real estate portfolios see frequent modifications — rent escalations, term extensions, space expansions, early terminations. Each modification requires remeasurement with a current discount rate. Spreadsheet-based teams find this unsustainable beyond 50-100 leases.
4. Multi-standard reporting
Organizations reporting under multiple standards (ASC 842 + IFRS 16, or GASB 87 + GASB 96) need parallel calculations from the same lease data. Without multi-standard support, this means maintaining duplicate data sets — doubling the work and the error risk.
5. Maintaining audit trails
Auditors need to trace every balance sheet number back to the source document. In spreadsheet workflows, this trail breaks whenever someone overwrites a formula, edits a cell, or creates a new version of the file. Dedicated software maintains an immutable audit trail from extraction through journal entry.
Spreadsheets vs lease accounting software
Spreadsheets are where most teams start — and where most eventually hit a wall. The question is not whether spreadsheets can handle lease accounting (they can, technically) but whether they should.
| Capability | Spreadsheets | Lease accounting software |
|---|---|---|
| Data entry | Manual typing | AI extraction from PDFs |
| Calculations | Custom formulas (error-prone) | Automated, audited engine |
| Modifications | Manual recalculation | Upload amendment, auto-remeasure |
| Audit trail | File versions (fragile) | Immutable, document-to-entry |
| Multi-standard | Duplicate workbooks | Parallel from single data source |
| Disclosures | Manual assembly | Auto-generated reports |
| Scale | Breaks at 50-100 leases | Handles thousands |
For a small portfolio (under 20 leases) with no modifications and a single standard, spreadsheets may suffice. For everything else, the risk of formula errors, lost audit trails, and unsustainable modification workflows makes dedicated software the more defensible choice.

Getting started with lease accounting
Whether you are implementing lease accounting for the first time or re-evaluating your current approach, the path forward follows the same structure:
- Audit your current state — how many leases do you have? Under which standards do you report? Where are your lease documents stored? Are you managing modifications systematically?
- Identify gaps — are there embedded leases in service contracts you have not accounted for? Are your calculations current after recent modifications?
- Choose the right tool — for portfolios beyond 50 leases, spreadsheets introduce unacceptable risk. Lease accounting software automates the mechanical work so your team focuses on judgment calls.
- Extract and verify — upload your lease documents and verify the extracted data. AI-powered extraction handles the volume; your team provides the expertise on edge cases.
- Go live and maintain — lease accounting is ongoing. Every reporting period requires journal entries, reconciliation, and potential remeasurement. The right platform makes this a routine process, not a quarterly fire drill.
Arvexi's approach
Arvexi was built in 2025 with AI as a core capability — not an afterthought. Upload any lease PDF and the AI reads the document, extracts every relevant term, classifies the lease, calculates the amortization schedule, and generates journal entries. Modifications? Upload the amendment. The AI recalculates automatically.
Support for ASC 842, IFRS 16, GASB 87, GASB 96, and FRS 102 runs simultaneously on the same portfolio — no duplicate data, no separate tools. A dedicated auditor portal gives external auditors read-only access to verify every calculation independently.
