The Unexpected $75,000 Taxable Income Surprise

The tax treatment of tenant improvement allowances depends heavily on how the lease and ownership of the improvements are structured. In general, when a landlord pays a cash allowance to a tenant for leasehold improvements, the payment may be taxable income to the tenant in the year it is received, while the improvements themselves are depreciated over time.

However, the Internal Revenue Code provides a limited safe harbor under IRC §110, which allows tenants to exclude certain construction allowances from income if the lease qualifies as a short-term lease of retail space (generally 15 years or less) and the funds are used for qualified real property improvements that revert to the landlord at the end of the lease.

If the safe harbor requirements are not met, the allowance may need to be recognized as taxable income by the tenant, even though the funds are used to build out the leased space.

This timing can create a particularly confusing situation when improvements are deducted in the opening year using accelerated depreciation or expensing, but the tenant improvement allowance is reimbursed later. In those cases, the reimbursement can create taxable income in the year the cash is received, because the business has already claimed the deduction for the improvements.

For that reason, tax advisors often emphasize reviewing lease agreements carefully and coordinating accounting treatment before construction begins, since small differences in lease language and ownership structure can determine whether the allowance is taxable income or excluded under Section 110.

Example Scenario:

$500K Leasehold Improvements and $75K Tenant Improvement Allowance

A franchise owner opens a new store.

Total Leasehold Improvements (LHI): $500,000

Landlord provides a Tenant Improvement Allowance (TI): $75,000

Construction happens late in the year, and the store opens in Year 1. The landlord reimbursement arrives in Year 2.

Opening Year (Year 1)

The owner spends $500,000 on build-out.

Because Qualified Improvement Property may qualify for bonus depreciation or Section 179, the business elects to expense the full amount.

Year 1 Tax Effect

Item	Amount
Leasehold Improvements	$500,000
Tax Deduction	$500,000

This produces a large deduction in Year 1, which reduces taxable income. At this point, the $75K TI allowance has not been received yet.

Tenant Improvement Allowance Arrives (Year 2)

The landlord reimburses $75,000.

Because the deduction was already taken in Year 1, the reimbursement may now be treated as income (unless Section 110 safe harbor applies).

Year 2 Tax Effect

Item	Amount
Tenant Improvement Allowance Received	$75,000
Taxable Income	$75,000

The owner might be surprised:

They thought the TI allowance simply offset construction costs.

But because the deduction already occurred in Year 1, the reimbursement now appears as income in Year 2.

Combined Effect

Year	Tax Event	Amount
Year 1	LHI expensed	($500,000) deduction
Year 2	TI allowance received	$75,000 income

This timing mismatch is one of the most common surprises in retail and franchise buildouts.
