ASC 340-40 Explained: Sales Commission Capitalization for Startups

ASC 340-40 (Other Assets and Deferred Costs: Contracts with Customers) is the part of US GAAP that decides whether the cost of winning or delivering a customer contract goes on the balance sheet or straight to the income statement. It was issued alongside ASC 606 in ASU 2014-09, and for most startups it matters for one reason: sales commissions earned for closing a deal must be capitalized and amortized, not expensed in the month they are paid.

The subtopic covers two kinds of cost. Costs of obtaining a contract are dealt with in ASC 340-40-25-1 through 25-4. Costs of fulfilling a contract are dealt with in ASC 340-40-25-5 through 25-8. Amortization and impairment of both are in the 35 paragraphs.

It applies to any company that prepares GAAP financial statements, public or private. There is no private-company alternative. If you only produce tax-basis or cash-basis books, it does not apply yet, but it will the moment an investor, lender or acquirer asks for audited GAAP statements, and restating two years of commissions after the fact is slower than doing it monthly.

ASC 340-40-25-1 requires an asset for the incremental costs of obtaining a contract with a customer if you expect to recover those costs. Paragraph 25-2 defines incremental: a cost you would not have incurred if the contract had not been obtained. Paragraph 25-3 adds that costs you would have incurred anyway are expensed when incurred, unless the customer is explicitly charged for them.

The test is simple to state. Ask whether the cost exists because this specific contract was signed. If yes, it is incremental.

Usually capitalized:

• Sales commissions paid to reps for closing a specific contract
• Commissions or accelerators paid to sales managers that are triggered by the same signed contract
• Referral or finder fees paid to third parties when a referred customer signs
• Employer payroll taxes on capitalized commissions (many companies include these; pick a policy and apply it consistently)

Usually expensed:

• Base salaries of sales, sales engineering and customer success staff
• Bonuses based on company-wide metrics or quotas not tied to specific contracts
• Marketing, events, content and paid acquisition
• CRM and sales tooling subscriptions
• Travel and pre-sales demo costs incurred whether or not the deal closes

Pre-sales engineering is the common gray area. Time spent on a proof of concept is incurred before you know whether the contract will be signed, so it fails the incremental test even if it helped win the deal.

ASC 340-40-25-4 lets you expense incremental costs of obtaining a contract as incurred if the amortization period of the asset you would otherwise recognize is one year or less. The key words are amortization period, not contract term.

That distinction trips up a lot of SaaS companies. A monthly or annual contract can still produce an amortization period longer than a year if the commission also relates to renewals you expect (more on that below). A 12-month contract with a large first-year commission and no renewal commission usually has an amortization period equal to the expected customer life, which is rarely under a year.

Where the expedient tends to work:

• Renewal commissions that are paid on each renewal at a rate commensurate with the original commission, so each one relates only to a one-year term
• Commissions on short professional services projects delivered within a year
• Commissions in businesses with genuinely short customer lives, supported by churn data

Most companies elect the expedient as an accounting policy and apply it consistently to similar contracts. Write the election down in your revenue and contract-cost policy memo with the data that supports a one-year-or-less period, because auditors will ask for it.

Costs to fulfill a contract are capitalized under ASC 340-40-25-5 only if they are not covered by another Topic and meet all three criteria: they relate directly to a contract or a specific anticipated contract, they generate or enhance resources you will use to satisfy performance obligations in the future, and you expect to recover them.

For a SaaS startup the usual candidate is setup or onboarding work that is not a distinct performance obligation, such as migrating a customer's data onto your platform. Costs of building the platform itself are not here; internal-use software development falls under ASC 350-40. Hosting costs that support the service as it is delivered are period costs.

General and administrative costs, wasted materials or labor, and costs tied to obligations already satisfied are always expensed. In practice, early-stage companies capitalize far fewer fulfillment costs than acquisition costs. The commission question is the one that moves the balance sheet.

ASC 340-40-35-1 requires amortizing the asset on a systematic basis consistent with the transfer to the customer of the goods or services the asset relates to. Those goods or services can include ones under specific anticipated contracts, such as renewals you expect.

The practical question is whether the commission relates only to the initial term or also to expected renewals. The commonly applied answer, discussed by the FASB-IASB revenue transition group, turns on whether renewal commissions are commensurate with the initial commission:

• If you pay the same rate on renewals as on new contracts, each commission relates to its own contract term. Amortize the initial commission over the initial term.
• If the renewal commission is lower (or zero), part of the initial commission is paying for renewals too. Amortize over the expected customer life, including anticipated renewals.

Estimate customer life from your own cohort data. A rough check is one divided by annual logo churn: 25% annual churn implies about four years. Seed-stage companies with thin history often use the contract term plus a conservative renewal assumption and revisit it each year. Straight-line is the usual pattern for ratable subscription revenue; if revenue ramps, a pattern that follows revenue is more consistent with 35-1.

If your estimate of the period changes, update the amortization prospectively. That is a change in estimate, not a restatement.

Here is a hypothetical seed-stage SaaS company. A rep closes a three-year contract billed annually at $120,000 per year and earns a 10% commission on first-year contract value: $12,000, paid in January. Renewal commissions are 2% of annual value ($2,400), which is not commensurate with the 10% initial rate. Historical cohorts suggest a typical customer stays four years, so the company amortizes the initial commission over 48 months.

Monthly amortization is $12,000 / 48 = $250. The entries:

1. January: debit capitalized contract costs $12,000, credit cash $12,000.
2. Each month: debit commission amortization expense (sales and marketing) $250, credit capitalized contract costs $250.

At the end of year 1, $3,000 of the $9,000 balance is classified as current and $6,000 as noncurrent. Without ASC 340-40, year 1 sales expense would be $9,000 higher.

The $2,400 renewal commission paid at the start of year 4 relates only to that one-year renewal term, so its amortization period is 12 months and the company can expense it under ASC 340-40-25-4 if it has elected the expedient.

ASC 340-40-35-3 requires an impairment loss when the carrying amount of the asset exceeds the remaining consideration you expect to receive for the related goods or services, less the costs directly related to providing them that you have not yet expensed.

In the example above, if the customer terminates after 18 months and pays nothing further, the remaining balance is $12,000 minus 18 × $250, or $7,500. There is no remaining consideration to recover it, so the $7,500 is written off in that month. A partial downsell would call for comparing the remaining balance with the reduced expected consideration.

At portfolio level, rising churn is a signal to shorten the amortization period for new and existing cohorts. Under ASC 340-40-35-6, impairment losses on these assets cannot be reversed later even if the customer comes back.

For federal income tax, ASC 340-40 does not control. Commissions paid to your own employees are compensation, deductible under IRC §162(a)(1), and Treas. Reg. §1.263(a)-4(e)(4)(ii) treats employee compensation (expressly including bonuses and commissions) as not facilitating the creation of an intangible. So employee commissions are generally deducted when paid or incurred under your method of accounting, even though GAAP spreads them over four years.

In the example, that leaves a $9,000 book-tax difference at the end of year 1: the GAAP asset is $9,000 and its tax basis is zero. At the 21% federal rate that is a $1,890 deferred tax liability before state taxes and any valuation allowance.

Third-party referral fees are different. Commissions paid to outside parties to obtain a customer contract are excluded from the $5,000 de minimis rule in §1.263(a)-4(e)(4)(iii)(B), so they may need to be capitalized for tax unless the 12-month rule in §1.263(a)-4(f) applies. Check this before you assume book and tax match. These rules were checked in October 2026 and were not changed by the One Big Beautiful Bill Act.

A workable ASC 340-40 process needs a written policy, contract-level data and a monthly schedule.

The policy memo should list which payments are capitalized, the amortization period and how you estimated it, whether you elected the 25-4 expedient and for which commission types, how you treat payroll taxes on commissions, and how you test for impairment.

The data comes from your CRM and commission plan: rep, customer, contract ID, contract start date, commission amount, renewal commission rate and termination date if any. Every capitalized dollar should tie to a signed contract.

The schedule tracks each commission (or monthly cohort) with its start date, period, monthly amortization and remaining balance, splits the balance between current and noncurrent, and writes off balances for churned customers. Below roughly a few dozen active contracts a spreadsheet is fine. Above that, a commission tool or your accounting system's amortization feature saves time.

We set this up for SaaS companies as part of our accounting and CFO work, usually alongside the ASC 606 revenue schedule so both use the same contract data. This is general guidance, not tax or accounting advice for your specific facts; your auditor's view on your policy elections is what ultimately counts.
