Accounting for Commissions: ASC 606 Capitalization and Amortization

Under ASC 606 and its companion cost guidance in ASC 340-40, accounting for sales commissions under the ASC 606 framework turns on a single question: was the commission an incremental cost of winning the contract? If yes, and the benefit period runs longer than a year, the commission is capitalized as an asset and amortized over the period the customer relationship is expected to last. If the benefit period is a year or less, an elective shortcut lets the company expense it immediately.

Which Commissions Have to Be Capitalized

ASC 340-40-25-2 defines incremental costs of obtaining a contract as costs the entity would not have incurred if the contract had not been obtained.¹ A sales commission is the textbook example named in the codification itself. No deal, no commission — that direct contingency is what makes the cost incremental and what triggers capitalization.

A second condition sits alongside the first and is easy to miss. Under ASC 340-40-25-1, the entity must expect to recover the capitalized amount, meaning future revenue from the contract has to be enough to support treating the commission as an asset.¹ A commission on a contract the company expects to lose money on fails that test.

The clearest qualifying cases are success-based payouts: commissions calculated as a percentage of contract value and paid only after the customer signs. Team bonuses tied to total bookings within a period also qualify, because the payout depends on landing contracts. The analysis always comes back to the plan structure. If no deal means no payout, the cost is incremental.

What Stays a Period Expense

ASC 340-40-25-3 draws the other side of the line. Costs that would have been incurred whether or not the contract was won must be expensed as incurred.¹ That sweeps in most of what a sales organization spends:

Fixed base salaries owed regardless of deals closed.
General overhead like office rent, CRM subscriptions, and sales administrative support.
Marketing, advertising, trade shows, and content lead generation.
Travel and entertainment for client dinners and prospect visits.
Pre-contract legal review and negotiation costs, which are incurred even when a deal falls through.

There is one narrow exception. If a non-incremental cost is explicitly chargeable to the customer whether or not the contract is obtained, it can be capitalized.¹ This rarely applies to commissions.

The One-Year Practical Expedient

ASC 340-40-25-4 offers an elective shortcut: if the amortization period of the resulting asset would be one year or less, the commission can be expensed as it is incurred and never touch the balance sheet.¹

The test is based on the expected amortization period, not the initial contract term. Anticipated renewals and follow-on contracts with the same customer have to be factored in. A 10-month contract where the average customer renews four times does not qualify, because the true benefit period runs well past 12 months.

The election is a policy choice. It has to be applied consistently to all contracts with similar characteristics. A company cannot capitalize commissions on some annual contracts while expensing them on other annual contracts with the same expected customer life.

The appeal is administrative. Capitalization means ongoing asset tracking, monthly amortization, and periodic impairment testing. For short-duration contracts, that overhead often is not worth it. Companies running annual subscriptions or short-term service agreements tend to benefit the most from the election.

Setting the Amortization Period

When the expedient does not apply, capitalization is mandatory and the hardest judgment call follows: how long to amortize. The codification requires a systematic method consistent with the pattern of transfer of the goods or services the asset relates to. Straight-line amortization is the default in most implementations unless the entity can show a meaningfully uneven transfer pattern.

Looking Beyond the Initial Contract Term

Most of the real complexity sits here. The amortization period has to include anticipated renewals if the original commission effectively secured the broader customer relationship rather than only the first contract. A subscription business with historical data showing the average customer stays five years should amortize the commission over five years, not over the initial one-year term.

Supporting an extended period takes evidence. A 90% annual renewal rate gives a defensible basis for looking past the initial term. Without reliable history — common for newer companies or newly launched products — a more conservative approach caps amortization at the non-cancelable contract term.

The period has to be reassessed whenever there is a significant change in the expected timing of the related transfers. Under ASC 340-40-35-2, that reassessment is treated as a change in accounting estimate, affecting only current and future periods.² The remaining balance is spread over the revised remaining life. Prior amortization is not restated.

The Commensurate Renewal Commission Test

If the company pays a renewal commission that is commensurate with the initial commission, the amortization period should not extend beyond the initial contract term. FASB clarified in BC309 of ASU 2014-09 that stretching amortization further would not be appropriate in that fact pattern.¹ The logic: a proportional renewal payout means the initial commission bought only the first contract, not the ongoing relationship.

Commensurate generally means reasonably proportional to the respective contract values. A 5% commission on both the initial and the renewal is commensurate. A 6% initial rate dropping to 2% on renewal is not; the gap signals the first payment was partly buying the longer-term relationship, which pushes the amortization period past the first term. The test looks at proportionality to contract value, not the level of effort involved.

Getting this judgment right matters. It can be the difference between amortizing a commission over one year and amortizing it over a decade, and it flows straight through to reported margins.

The Journal Entries

At payment, debit a balance sheet account (commonly “Capitalized Contract Acquisition Costs”) and credit Cash for the gross commission amount. The asset is classified as non-current unless the entire amortization period falls within the next twelve months.

Each period, debit “Amortization Expense — Contract Acquisition Costs” and credit accumulated amortization. The mechanics mirror depreciation of a fixed asset. The expense generally sits within selling, general, and administrative on the income statement, matching where the commission would have landed under immediate expensing.

Impairment Testing

Capitalized commission assets have to be assessed for impairment whenever facts and circumstances suggest the carrying amount may not be recoverable. Common triggers include a customer entering financial distress, a significant drop in expected renewals, or a discontinued product line.

Under ASC 340-40-35-3, the asset is impaired when its carrying amount exceeds the remaining consideration the entity expects to receive from the customer (including amounts already received but not yet recognized as revenue), less the direct costs of providing the related goods or services that have not yet been expensed.² It is a forward-looking profitability test applied at the contract level, or at the portfolio level if contracts share similar characteristics.

If impairment exists, write the carrying amount down. Debit an impairment loss (operating expense) and credit the asset directly. The reduced carrying amount becomes the new cost basis going forward.

Reversal is not permitted. ASC 340-40-35-6 prohibits reinstating a previously recognized impairment loss even if the customer’s situation improves and the contract becomes profitable again.² Once written down, the loss is permanent.

Commission Clawbacks

Many plans require the rep to return the commission if the customer cancels within a defined window. That does not reduce the amount capitalized at inception. Once a contract qualifies for recognition under ASC 606’s Step 1 (meaning the parties are committed to perform), the full commission is capitalized.³ If the customer later cancels and the clawback triggers, the entity reassesses whether a valid revenue contract still exists and tests the contract cost asset for impairment at that point. The adjustment happens when circumstances change, not at inception based on the possibility.

The Portfolio Approach

Tracking commission assets one contract at a time is impractical for companies with thousands of customers. The portfolio approach in ASC 606 is generally accepted for contract costs as well, provided the effect would not differ materially from applying the guidance contract by contract. Grouping contracts with similar characteristics — same product line, comparable expected customer life, similar commission rates — and amortizing pooled costs on the same schedule is often the only workable method for high-volume subscription books.

Required Disclosures

ASC 340-40-50-2 and 50-3 require specific footnote disclosures for capitalized contract acquisition costs at public entities.¹ Public companies disclose:

The judgments applied in determining which costs to capitalize, including how incremental costs were identified.
The amortization method used and how the expected benefit period was established.
Closing asset balances net of accumulated amortization, broken out by main category.
Total amortization expense and any impairment losses recognized during the period.

Non-public entities carry a lighter load. Under ASC 340-40-50-4, private companies, along with certain not-for-profit entities and employee benefit plans that do not file with the SEC, may elect to skip these disclosures.¹ Most private companies with material capitalized commission balances still provide some level of disclosure to satisfy auditors and lenders. If the one-year practical expedient is elected, that policy choice should also be disclosed as a significant accounting policy.
