How do you account for sales commissions under ASC 340-40?

ASC 340-40RevenueContract costsUpdated July 2026
The short answer

Sales commissions that are incremental costs of obtaining a customer contract — costs the company would not have incurred had the contract not been obtained — are capitalized as a contract cost asset under ASC 340-40-25-1 and amortized on a systematic basis consistent with the transfer of the related goods or services. When commissions paid on renewal are not commensurate with the initial commission, the amortization period extends beyond the initial term to the expected customer life. As a practical expedient, commissions may be expensed as incurred when the amortization period would be one year or less.

Which commissions qualify for capitalization?

The test is incrementality (ASC 340-40-25-2): would the cost have been incurred if the contract had not been obtained? Commissions paid only on a signed deal are incremental. Costs that fail the test — salaries of the sales team, commissions on proposals regardless of outcome, most sales-manager bonuses tied to aggregate targets — are expensed as incurred unless they are explicitly chargeable to the customer.

Judgment areas practitioners see most often:

  • Tiered or accelerator commissions are generally incremental to the pool of contracts that earned them and are capitalized, allocated on a reasonable basis.
  • Fringe benefits and payroll taxes on commissions are incremental (they would not arise without the commission) and are typically capitalized with it.
  • Clawback provisions do not prevent capitalization; they factor into the asset's measurement and impairment assessment.

Over what period do you amortize?

ASC 340-40-35-1 requires amortization "on a systematic basis that is consistent with the transfer to the customer of the goods or services to which the asset relates." The load-bearing question is whether the asset relates only to the initial contract term or also to anticipated renewals:

Fact patternAmortization period
Renewal commission commensurate with the initial commissionInitial contract term
Renewal commission not commensurate (lower or none)Expected period of benefit, typically estimated customer life
Amortization period would be 12 months or lessPractical expedient: expense immediately (ASC 340-40-25-4)

"Commensurate" is evaluated against the level of effort to obtain the renewal, but in practice most companies compare commission rates: a 6% initial commission and a 2% renewal commission are not commensurate, so the initial asset amortizes over expected customer life (initial term plus expected renewals).

Worked example

A SaaS company pays a salesperson a commission on a new 3-year contract: 60% at signing and 40% if the customer renews. Expected customer life is 6 years.

  • The signing commission is an incremental cost of the initial contract. Because the renewal commission (40% of one commission, paid once) is not commensurate with the signing commission, amortize the signing commission over the 6-year expected customer life.
  • The renewal commission, when paid, is an incremental cost of obtaining the renewal and amortizes over the renewal's period of benefit.

Illustrative entries for a $30,000 signing commission:

At signing
Dr. Contract cost asset (ASC 340-40)   30,000
Cr. Commission payable                          30,000

Each year (6-year expected customer life, straight-line)
Dr. Amortization expense                5,000
Cr. Contract cost asset                          5,000

Straight-line is acceptable when it approximates the pattern of transfer; a usage- or revenue-based pattern is used when transfer is not ratable.

Impairment and presentation

The asset is assessed for impairment under ASC 340-40-35-3 when the carrying amount exceeds the remaining consideration expected less directly related costs. Amortization is presented consistently with the nature of the cost — most companies present it in sales and marketing expense, not as a reduction of revenue.

Required disclosures

ASC 340-40-50 requires the closing balances of contract cost assets, the amortization recognized in the period, the method used, and the judgments made in determining the amounts — including the practical expedient election if used.

Frequently asked questions

Can we just expense all commissions as incurred?

Only if the amortization period for the asset would be one year or less (the ASC 340-40-25-4 practical expedient), applied as a policy election. For multi-year contracts, or one-year contracts with non-commensurate renewals, capitalization is required.

Do payroll taxes on commissions get capitalized too?

Generally yes — employer payroll taxes and similar fringe costs are incremental to the commission itself and are typically capitalized with it.

What does 'commensurate' mean for renewal commissions?

The renewal commission reflects a level of effort comparable to obtaining the initial contract. In practice, companies compare rates: a renewal commission materially lower than the initial commission is not commensurate, which extends amortization of the initial asset beyond the initial term.

How is expected customer life estimated?

From historical churn and renewal data, typically at a portfolio level, considering the technology and competitive environment. It is a significant judgment that auditors expect to be supported and disclosed.
