When a salesperson earns a commission on a three-year deal, GAAP treats that commission as an asset that pays off over the customer relationship, not as a one-time expense. ASC 340-40, adopted alongside ASC 606, sets the rules. For SaaS companies with multi-year contracts or long customer lives, the effect on reported operating expense can be meaningful.
What gets capitalized
Incremental costs of obtaining a contract: costs you would not have incurred if the contract had not been obtained.
| Cost | Capitalize? |
|---|---|
| Sales commissions earned on signing | Yes |
| Employer payroll taxes on those commissions | Yes |
| Commissions paid to managers based on the specific contract | Usually yes |
| Base salaries of sales staff | No |
| Commissions based on non-contract metrics (team quota, activity) | Usually no |
| Referral fees to third parties for a specific contract | Yes |
The amortization period
Amortize on a systematic basis consistent with the transfer of the services the asset relates to. That is often longer than the initial term when renewals are expected and renewal commissions are lower than the initial commission. Many companies support a period based on expected customer life from retention data.
The practical expedient
If the amortization period would be one year or less, you may expense the cost when incurred. Monthly plans with commissions that relate only to the first year frequently qualify.
Building the schedule
- Pull commissions by contract from payroll or the commission tool.
- Assign each to a contract and an amortization period.
- Amortize monthly to sales and marketing expense.
- Track the asset balance by contract and write off the remaining balance when a customer churns.
- Split the asset between current and non-current.
Why it matters
Capitalization smooths operating expense and better matches cost with revenue. It also changes the picture on CAC and payback if you calculate them from GAAP expense, so we calculate unit economics on cash commissions paid and show the GAAP view separately.
A worked example
A sales rep earns a $12,000 commission on a new contract worth $40,000 a year for two years. Renewals pay a 2% commission, which is not commensurate with the initial 10%, and retention data supports an expected customer life of five years.
- Capitalize $12,000 plus the related employer payroll taxes.
- Amortize over the five-year expected benefit period: $200 a month plus the payroll-tax portion.
- If the customer churns in year two, write off the remaining balance in that month.
If the renewal commission had matched the initial rate, the initial commission would typically be amortized over the two-year contract term instead.
Choosing the benefit period
Support the period with your own data:
- Historical customer lifetimes by segment
- Expected technology life of the product or contract
- Whether renewal commissions are commensurate with the initial commission
Document the analysis once and revisit it annually. A portfolio approach, applying one period to contracts with similar characteristics, is common and practical.
Tax is different
For federal income tax, commissions are generally deducted under the tax rules for those costs, not the GAAP amortization schedule. The difference creates a book-tax difference to track, which matters for any deferred tax calculation.
Systems
Commission tools can export commissions by deal, which makes the schedule straightforward. If commissions are paid through payroll with no deal detail, start capturing the deal identifier with each payment; it saves a reconstruction later.

Questions founders ask
Do we have to capitalize commissions if we are not audited?
GAAP requires it whenever the amortization period is longer than one year. If you report GAAP financials to investors or a lender, capitalize; tax treatment is separate.
Are commissions on renewals capitalized too?
Yes, if they are incremental costs of obtaining the renewal contract. When renewal commissions are not commensurate with the initial commission, the initial commission is often amortized over a longer expected customer life.
