ASC 842 explained: lease accounting for startups, what triggers it, and how to actually deal with it

The day a startup signs its first office lease is also the day a piece of technical accounting becomes the founder’s problem. ASC 842 — the lease accounting standard that took effect for private companies in 2022 — requires that almost every lease your company has be recorded on the balance sheet, with corresponding rules for how the lease expense flows through the income statement.

If you have an office lease, an equipment lease, a vehicle lease, or even some software arrangements, ASC 842 applies. Most founders don’t realize this until their first audit, when the auditor asks for the lease schedule and the answer is “what lease schedule?” By then, the work to remediate is substantial — often 3–6 months of cleanup spread across the finance team and outside specialists.

This post is for founders signing their first material leases, finance leads at companies preparing for their first audit, and operators trying to understand what ASC 842 actually requires. The goal: a clear, operator-grade view of the standard, what it requires, what it costs to implement, and the mistakes that turn it into an expensive problem.

What ASC 842 actually requires

The previous lease accounting standard (ASC 840) treated most leases as off-balance-sheet items — companies disclosed their lease commitments in the footnotes but didn’t book them as liabilities. ASC 842 changed this fundamentally.

Under ASC 842, almost every lease — defined as any contract that conveys the right to control the use of an identified asset for a period of time in exchange for consideration — must be recognized on the balance sheet. Specifically:

• A right-of-use (ROU) asset is recorded representing your right to use the underlying asset
• A lease liability is recorded representing your obligation to make lease payments
• Both are measured at the present value of the lease payments at lease commencement

The income statement treatment depends on whether the lease is classified as an operating lease or a finance lease (the new term for what used to be called a capital lease):

• Operating lease: A single lease expense recognized on a straight-line basis over the lease term. This is what most office leases, equipment leases, and vehicle leases end up classified as.
• Finance lease: Interest expense (front-loaded) plus amortization expense (straight-line). This typically applies to leases that transfer substantially all the risks and rewards of ownership — for example, a 7-year lease on equipment that has an 8-year useful life.

For most startups, the leases that need to be accounted for are operating leases. The mechanics are the same: ROU asset and lease liability on the balance sheet, single lease expense on the income statement.

What counts as a “lease” under ASC 842

This is where founders get tripped up. ASC 842 has a specific definition that’s broader than what most people intuitively think of as a “lease.”

A contract is a lease (or contains a lease) if it conveys the right to control the use of an identified asset for a period of time. The two key criteria:

1. There has to be an identified asset. The contract must specify the asset, either explicitly (this particular machine, this office space) or implicitly (the lessor has no practical ability to substitute the asset).

2. You have to control the use of the asset. Specifically, you must have the right to obtain substantially all of the economic benefits from using the asset AND the right to direct how and for what purpose the asset is used.

Common examples of what counts as a lease:

• Office space lease (almost always a lease)
• Equipment lease — copiers, servers, lab equipment, manufacturing equipment
• Vehicle lease — company cars, trucks, delivery vans
• Coworking space agreements (usually NOT a lease if there’s no identified space, but sometimes a lease if you’re paying for a specific dedicated office)
• Cloud computing arrangements — usually NOT a lease (because the customer doesn’t control the underlying servers)
• Software-as-a-service — usually NOT a lease
• Data center colocation — depends on the specifics; often a lease if you control specific racks or cages

The “embedded lease” trap: Some contracts that aren’t called leases contain lease components. For example, a services contract that includes the right to use specific equipment may contain an embedded lease. A typical case: a managed IT services contract that gives you the right to use specific servers at the provider’s data center. The service portion isn’t a lease; the dedicated server portion may be. Identifying embedded leases is one of the harder parts of ASC 842 compliance.

When does ASC 842 apply to you?

The short answer: if you’re a private company that prepares GAAP financial statements, ASC 842 applies to your fiscal year that began on or after December 15, 2021. For most startups, this means fiscal years 2022 and beyond.

Practically, you need to comply with ASC 842 if:

• You’re audited (every audited company is on GAAP)
• You’re preparing for an audit (your auditor will require it)
• You’re preparing for a fundraise where the lead investor will want audited or compliant financials
• You’re preparing for M&A and the acquirer will run quality of earnings analysis on your financials
• You’re preparing for an IPO (where SEC requirements apply)

You probably don’t need to fully implement ASC 842 right now if:

• You’re truly early-stage (pre-revenue or under $1M ARR)
• You don’t have any material leases
• You don’t anticipate audit, fundraise, or M&A in the next 12–24 months
• Your books are still on cash basis and you have no intention of switching to accrual soon

That said, the moment any of those situations changes, ASC 842 becomes immediately relevant — and the work to implement it correctly takes time. Companies that anticipate any of the triggering events within 24 months should start ASC 842 work proactively rather than reactively.

How ASC 842 actually works mechanically

For each lease, you need to compute and track several pieces of information:

At lease commencement:

1. Identify the lease term. This includes the noncancellable period plus any periods covered by options to extend that you’re reasonably certain to exercise. A 5-year lease with a 5-year renewal option you’ll likely take is a 10-year lease for accounting purposes.
2. Identify all lease payments. This includes base rent, fixed escalations, residual value guarantees, and termination penalties (if termination is reasonably certain not to occur). Variable payments tied to indexes (like CPI) are included at initial measurement; variable payments tied to usage or performance generally aren’t.
3. Determine the discount rate. Use the rate implicit in the lease if it’s known. Most leases don’t disclose this rate explicitly, so you use the lessee’s incremental borrowing rate — the rate the company would pay to borrow on a collateralized basis for a similar term. For private companies, ASC 842 also permits using the risk-free rate for the lease term, which is a simpler alternative.
4. Calculate the lease liability. Present value of all future lease payments using the discount rate.
5. Calculate the right-of-use (ROU) asset. Start with the lease liability, then add prepaid lease payments and initial direct costs, then subtract lease incentives received. For most simple office leases, the ROU asset roughly equals the lease liability.
6. Classify the lease. Operating vs. finance. The classification is based on whether the lease effectively transfers ownership economically — specific tests in the standard determine this.

Each subsequent period:

• Operating lease: Recognize lease expense on a straight-line basis (total lease payments divided by lease term). Increase the lease liability by the implicit interest, decrease it by the cash payment. Adjust the ROU asset by the difference between the straight-line expense and the interest accretion.
• Finance lease: Recognize interest expense on the lease liability and amortization expense on the ROU asset separately. The interest is front-loaded; the amortization is straight-line.

At lease modification, termination, or end:

Remeasure as required by the standard. Modifications that change scope, term, or payments often require resetting the lease liability and ROU asset.

This is enough mechanics that doing it by hand in Excel for more than 2–3 leases becomes impractical. Most companies use lease accounting software (LeaseQuery, Trullion, Visual Lease, Cradle Accounting, etc.) starting at the point where they have 3–5 leases or any moderately complex lease.

What ASC 842 implementation actually costs

The cost depends entirely on whether you’re implementing the standard cleanly from scratch or remediating a prior failure to implement.

Clean implementation:

For a company with 1–3 simple leases (one office, maybe a copier or two), the implementation cost is small:

• Initial setup: $5,000 – $15,000 (one-time)
• Annual maintenance: $1,500 – $5,000 (integrated into ongoing accounting work)
• Software (if needed): $0 – $3,000/year depending on lease count

For a company with 5–15 leases across multiple offices, equipment, and vehicles:

• Initial setup: $15,000 – $35,000
• Annual maintenance: $5,000 – $15,000
• Software: $3,000 – $12,000/year

Remediation (cleanup of prior non-compliance):

This is dramatically more expensive because the work involves identifying and reconstructing historical lease records, applying the standard retroactively, and often working with auditors to validate the result.

• Remediation cost: $35,000 – $150,000+ depending on scope
• Audit fee impact: typically 20–40% increase to audit fees for the first audit after remediation

The pattern: clean implementation costs an order of magnitude less than remediation. The companies that get this right are the ones that engage with ASC 842 before their first audit, not during it.

The mistakes we see consistently

Mistake 1: Treating coworking space as “not a lease.”

Some coworking arrangements are leases, some aren’t. A dedicated office with a specific suite number that you have exclusive use of is almost certainly a lease. A hot desk membership where you have access to any available seat usually isn’t. Founders often assume the entire coworking category is exempt — it isn’t.

Mistake 2: Missing embedded leases in service contracts.

Managed services contracts, equipment-as-a-service arrangements, and outsourced manufacturing contracts often contain embedded leases. The contract needs to be reviewed for whether there’s an identified asset that you control. This is one of the most-missed elements of ASC 842 compliance.

Mistake 3: Forgetting about non-real-estate leases.

The office lease is obvious. The copier lease, the company vehicles, the lab equipment, the IT hardware on multi-year contracts — these all qualify as leases under ASC 842 and are often overlooked.

Mistake 4: Using the wrong discount rate.

Companies sometimes use a too-low rate (the rate on a government bond) or a too-high rate (their cost of capital from venture investors). The correct rate is the incremental borrowing rate — what the company would pay to borrow on a collateralized basis for a similar term — or for private companies, the risk-free rate election. Using the wrong rate produces wrong lease liability and ROU asset values that auditors will challenge.

Mistake 5: Not updating for modifications.

When a lease is modified (extended, expanded, renegotiated), the lease liability and ROU asset usually need to be remeasured. Companies that signed a lease three years ago and then renegotiated the rent during the pandemic often haven’t updated their ASC 842 records — creating a real audit issue.

Mistake 6: Treating short-term leases as exempt without applying the right election.

There’s a short-term lease exception in ASC 842 for leases with a term of 12 months or less and no purchase option that’s reasonably certain to be exercised. You can elect to apply this exception by class of underlying asset (e.g., all your <12-month vehicle leases). But you have to actually make the election and document it; companies that just informally ignore short-term leases are noncompliant.

Mistake 7: Forgetting about lease incentives.

Tenant improvement allowances, rent abatements, and other lease incentives need to be properly accounted for. Companies that received a TI allowance and just expensed it as a rent reduction over time are usually getting the accounting wrong.

How to actually get this right

The pragmatic playbook for ASC 842 compliance at a startup:

Step 1: Identify all your leases. Real estate, equipment, vehicles, services contracts with embedded leases. Make a complete list with the underlying contracts. This is the longest part of the process — typically a 2–4 week effort even for simple companies.

Step 2: Extract the key data. Lease term, payment schedule, escalations, options to extend, renewal terms, lease incentives, initial direct costs. Get this into a structured format (spreadsheet for a few leases, software for more).

Step 3: Classify each lease. Operating vs. finance. For most startups, almost everything is operating, but the classification needs to be documented for each lease.

Step 4: Calculate the initial measurements. ROU asset and lease liability at commencement, using the appropriate discount rate. Document the discount rate methodology.

Step 5: Set up the ongoing accounting. Monthly journal entries for lease expense, interest accretion, and asset/liability movements. This either lives in your accounting software (some integrations exist for QuickBooks Online, NetSuite, Sage Intacct) or in dedicated lease accounting software with sync to the GL.

Step 6: Document the policies and judgments. Auditors will want to see documented positions on discount rate methodology, lease term determination, short-term lease elections, and embedded lease analyses. Build this documentation as you go, not at audit time.

Step 7: Plan for modifications. Every time a lease changes — new lease signed, existing lease extended, payments renegotiated — the records need to be updated. Build a process to flag modifications so they don’t get missed.

Software options worth knowing about

For startups with more than 2–3 leases, dedicated lease accounting software is almost always worth it. The pricing has come down significantly over the last few years.

LeaseQuery / FinQuery. Established platform, well-known to auditors, used by mid-market companies. Pricing typically $5K–$15K/year depending on lease count and features.

Trullion. Modern, AI-assisted lease abstraction (uploads PDF leases and extracts key data automatically). Pricing comparable to LeaseQuery.

Visual Lease. Established player, broad feature set, more enterprise-focused. Higher pricing.

Cradle Accounting. Built specifically for startups and mid-market. More accessible pricing ($3K–$8K/year for typical startup-scale usage).

Direct integrations. NetSuite has built-in lease accounting. Sage Intacct has lease accounting modules. For QuickBooks Online users, integration with one of the above platforms is typically the right path.

For companies with 1–3 leases, a well-built Excel model is acceptable — but the time savings from software at the 4–5 lease threshold usually justifies the cost.

When to bring in operator support

ASC 842 is one of those topics where a few hours of experienced help saves significant downstream cost. Most fractional CFO firms refer this work out because the technical accounting required is genuinely specialized. Pegacorn handles ASC 842 implementation and remediation in-house.

You probably don’t need outside help if you have a strong in-house controller with ASC 842 experience and you’ve been doing the accounting correctly from the start.

You likely do want operator support if:

• You’re about to sign your first material lease and want to set up ASC 842 correctly from day one
• You’re preparing for your first audit and haven’t yet implemented ASC 842
• Your auditor has flagged ASC 842 issues in a prior period and you need to remediate
• You’ve signed several leases without implementing the standard and need to catch up before something forces the issue
• You’ve inherited lease accounting that you suspect was done incorrectly

Pegacorn Group works with venture-backed startups on ASC 842 implementation, remediation, and ongoing lease accounting compliance. If your lease accounting needs a real review — or you’re trying to set it up correctly from the start — let’s talk.
