Lease commission amortization is the practice of capitalizing a broker’s fee at lease commencement and expensing it in equal monthly amounts over the life of the lease, rather than taking the full hit in the period the commission was paid. Under ASC 842, the commission qualifies as an initial direct cost, sits on the balance sheet as an asset, and moves to the income statement one month at a time. Tax treatment follows a parallel but separate track under IRC Sections 178 and 263, and the two schedules rarely match.
Which Commissions Get Capitalized
ASC 842 defines initial direct costs as incremental costs that would not have been incurred if the lease had not been obtained. That word “incremental” is the whole test. If the payment exists only because the lease closed, capitalize it. If it would have been paid regardless, expense it now.
An external broker commission is the clean case. The broker earns the fee only on execution, so the full amount qualifies. ASC 842-10-30-9 lists commissions as an example, and ASC 842-10-55-241 illustrates capitalizing a broker commission because it was “incurred only as a direct result of obtaining the lease.”1DART – Deloitte Accounting Research Tool. 6.11 Initial Direct Costs The rule applies the same way to lessees and lessors.
Internal payments can qualify too, but only when contingent on signing. An employee bonus tied to lease execution is capitalizable. A fixed salary is not, even if that employee negotiated the deal full-time, because the employer would have paid the salary either way.1DART – Deloitte Accounting Research Tool. 6.11 Initial Direct Costs
Legal fees trip people up. Negotiating terms, drafting standard agreements, and running credit checks on a prospective tenant are not initial direct costs, because the attorney gets paid whether or not the tenant signs. Only a true success fee, payable only on execution, could qualify. Most legal fees related to leasing are expensed as incurred. General overhead, marketing, administrative salaries, and due diligence costs fall on the same side of the line.
The One-Year Short Cut
Not every commission needs a multi-year schedule. Under ASC 340-40-25-4, an entity can expense the incremental costs of obtaining a contract immediately when the amortization period would be one year or less. So a broker fee on a twelve-month lease can go straight to expense. The expedient has to be applied consistently across all qualifying contracts, not cherry-picked by deal.
Calculating the Monthly Amortization
Amortization runs from the lease commencement date, not the date the commission was paid and not the date the lease was signed. If a broker was paid three months before the tenant took possession, the meter still starts at commencement.
The term used for the calculation includes any renewal options that are “reasonably certain” to be exercised. That is a judgment call driven by the economics. A five-year lease with a five-year renewal at well-below-market rent will almost certainly be exercised, so the amortization period is ten years. A renewal at above-market rates, with nothing tying the tenant to the space, is not reasonably certain and stays out of the calculation.
The method is straight-line. Divide the capitalized commission by the number of months in the amortization period. A $48,000 commission on a 96-month lease produces $500 per month. For operating leases, ASC 842 requires the lessee to recognize a single lease cost on a straight-line basis, so an initial direct cost folded into the right-of-use asset follows the same pattern.
The Journal Entries
At commencement, capitalize the full commission. For a $36,000 fee on a six-year lease:
- Debit Deferred Lease Commission (asset) $36,000
- Credit Cash or Accounts Payable $36,000
That creates a non-current asset. For lessees, the amount is typically rolled into the right-of-use asset rather than tracked on its own line. For lessors, the deferred commission often sits as its own asset or inside “other assets.”
Each month, move a slice to the income statement:
- Debit Amortization Expense $500
- Credit Deferred Lease Commission (or Right-of-Use Asset) $500
The expense lands within operating expenses. The remaining balance on the asset declines in a straight line to zero by the end of the term.
Modifications and Extensions
When a lease is modified, the remaining unamortized commission is recalculated prospectively. Say a $20,000 commission was capitalized on a five-year lease, and two years in the tenant extends for another three years. At the modification date, $12,000 remains unamortized. That $12,000 now amortizes over the six years still remaining after the modification, giving a new monthly charge of about $167. The original schedule stops from the modification date forward.2Deloitte. ASC 842-10 Roadmap Leasing Chapter 8 Lessee Accounting 8-6 Lease Modifications
Any new commission paid to secure the extension is a separate initial direct cost. It gets its own capitalization entry and its own schedule over the renewal period. The two assets then run in parallel.
Early Termination
If the lease ends before its scheduled expiration, the remaining balance is written off in the period of termination. ASC 842-20-40-1 requires the lessee to derecognize the right-of-use asset and lease liability, with any difference recognized as a gain or loss.3Deloitte. 8.7 Derecognizing a Lease If $10,000 of commission remains unamortized:
- Debit Loss on Lease Termination $10,000
- Credit Deferred Lease Commission $10,000
The full balance hits the income statement at once. There is no option to spread the loss.
Partial terminations, where a tenant gives back some square footage and keeps the rest, are treated as modifications. Write off a proportionate share of the deferred commission for the surrendered space and keep amortizing the rest over the adjusted term for the retained space.3Deloitte. 8.7 Derecognizing a Lease
Impairment
A capitalized commission, whether embedded in the right-of-use asset or on its own line, is subject to impairment testing under ASC 360 when a triggering event occurs. Common triggers include a major tenant bankruptcy, a significant decline in the property’s market value, or a decision to sublease at a loss. When a trigger hits, compare the carrying amount of the asset (or asset group containing it) to the undiscounted future cash flows expected from the lease. If the carrying amount is higher, write the asset down to fair value and recognize the difference as an impairment loss. The write-down is permanent under current GAAP; the asset cannot be written back up if conditions improve.
Tax Treatment Runs on a Separate Schedule
The IRS does not allow an immediate deduction for a lease commission. Section 162 lists commissions as a deductible business expense, but it cross-references Section 263, which requires capitalization of amounts that produce benefits beyond the current tax year.4eCFR. 26 CFR 1.162-1 – Business Expenses Treasury Regulation Section 1.263(a)-4 lists leases among the intangibles subject to capitalization and points to Section 1.167(a)-3 for amortization.5IRS. Treasury Decision 9107 – Section 1.263(a)-4 Amounts Paid to Acquire or Create Intangibles
The 75% Rule Under Section 178
IRC Section 178 sets the tax amortization period for a lessee. The default period is the remaining initial lease term. But if less than 75% of the cost is attributable to the initial term, the period must include all renewal options and any other period the parties reasonably expect the lease to continue.6Office of the Law Revision Counsel. 26 U.S. Code 178 – Amortization of Cost of Acquiring a Lease
For a flat-rate lease, the attribution roughly tracks the calendar, so the test compares the initial term to the total foreseeable term. When the initial term is 75% or more of the total, use the initial term. When it is less, stretch the schedule across the whole foreseeable life, renewals included. A lessee with a five-year initial term and two five-year renewal options could end up amortizing over 15 years for tax, even when the GAAP schedule uses only ten.
Early Termination for Tax
When a lease terminates early, the remaining unamortized tax basis is generally deductible as a loss under Section 165 in the year of termination. To claim an abandonment loss, the taxpayer has to show both an intent to abandon and an affirmative act that irrevocably cuts ties to the asset. Internal decisions and non-use of the space do not clear the bar. The IRS looks for an identifiable event observable to outsiders, such as formally surrendering the premises to the landlord.7IRS. Rev. Rul. 2004-58
The Book-Tax Difference
Because GAAP and tax use different tests for setting the amortization period, the deferred commission almost always has a different book basis than tax basis. GAAP includes renewals that are reasonably certain. Tax runs on the initial term, unless the 75% rule pushes it out to the full foreseeable life. Keep parallel schedules for each commission, one for books and one for tax, and reconcile the temporary difference each reporting period as a deferred tax asset or liability.
What to Disclose
ASC 842 has specific disclosure requirements that touch capitalized lease costs. When initial direct costs are embedded in the right-of-use asset, lessees have to disclose those assets in the footnotes if they are not on their own balance sheet line. Finance lease right-of-use assets and operating lease right-of-use assets cannot be combined into one line, and the notes have to identify which balance sheet line contains each. For entities with material deferred commission balances, the footnotes should describe the capitalization policy, the amortization method, and the total amount expensed during the period. Auditors expect enough specificity for a reader to see how the entity decided which costs were incremental and how it set the term, particularly when renewal options are in play.
