Straight-Line Rent for Commercial Landlords: A Worked Example

Straight-line rent means recognizing the total fixed rent from an operating lease evenly across the lease term, instead of following the cash schedule. When a lease has free rent months or annual escalations, the rent you report each month differs from the rent you bill, and the difference builds up as a straight-line rent receivable that unwinds to zero by the end of the lease.

Commercial landlords who prepare GAAP-basis financials, have them reviewed or audited, or report to institutional partners need to get this right. Here is how it works, with a full five-year example.

Why Do Commercial Landlords Straight-Line Rent?

Under ASC 842, a lessor with an operating lease recognizes the fixed lease payments as income on a straight-line basis over the lease term, unless another systematic basis better represents how the benefit is used. In practice, straight-line is the standard approach for commercial leases.

The reasoning is simple. A five-year lease with three free months and rising rent is one deal. Reporting zero income in the first three months and peak income in year five misrepresents its economics.

What Goes Into the Straight-Line Calculation?

Include:

• Base rent for the full lease term
• Fixed, scheduled escalations
• Free rent periods (as zero-payment months)
• Fixed payments that are part of the lease consideration

Generally exclude:

• Variable payments, such as CAM recoveries based on actual costs
• Percentage rent tied to tenant sales
• Escalations tied to an index like CPI, beyond the amount known at commencement

The lease term usually starts when the tenant gets possession, which may be before rent starts. That detail matters: a fit-out period before rent commencement is part of the term.

A Worked Example: Five Years, Free Rent and 3% Escalations

A tenant signs a five-year office lease starting January 1:

• Base rent of $10,000 per month in year one
• The first three months free
• Rent increases 3 percent each year

Step 1: Total the cash rent

Step 2: Spread it evenly

Total rent of $607,096.32 divided by 60 months is $10,118.27 per month, or $121,419.26 per year (year five absorbs two cents of rounding).

Step 3: Track the receivable

In year one, the landlord reports $121,419 of rental income while collecting $90,000. The $31,419 difference is booked as a straight-line rent receivable. From year two onward, cash rent exceeds recognized rent and the receivable winds down to zero at the end of the lease.

What Are the Journal Entries?

Each month during the free-rent period:

• Debit straight-line rent receivable $10,118.27
• Credit rental income $10,118.27

Each month once rent is billed, for example in year one after the free months:

• Debit tenant receivable $10,000.00 (the amount billed)
• Debit straight-line rent receivable $118.27
• Credit rental income $10,118.27

In later years, when billed rent exceeds the straight-line amount, the straight-line receivable is credited for the difference.

Most commercial property software, including Yardi Voyager and MRI, can calculate and post straight-line entries automatically from the lease setup. The calculation is only as good as the lease abstraction behind it.

What Happens When a Lease Changes or a Tenant Leaves?

• Lease modification. An amendment that changes rent or term usually requires recalculating straight-line rent from the modification date over the remaining term.
• Early termination. If the lease ends early, any remaining receivable is written off, which can create a noticeable one-time charge.
• Collectibility. If collecting the remaining lease payments is no longer probable, ASC 842 generally requires switching to recognizing income as cash is received and writing off the receivable.

Do You Straight-Line Rent for Tax Too?

Usually not. For federal income tax, most landlords report rent when it is received or due under the lease. Section 467 can require accrual-type treatment for certain larger leases with deferred or stepped rent. That is a tax question, so confirm with your tax adviser rather than assuming GAAP and tax match.

That difference is also why your GAAP financials and your tax return will show different rental income, and why a reconciling schedule is useful for your CPA.

Getting Straight-Line Rent Right

Straight-line rent errors usually come from incomplete lease abstraction: a missing free rent period, an escalation entered as a percentage instead of a fixed amount, or the wrong commencement date.
