The Tax Cuts and Jobs Act (TCJA) of 2017 significantly restricted the deduction of business-related interest expense under Section 163(j), limiting the deduction to 30% of adjusted taxable income (ATI) plus business interest income and floor plan financing interest. Initially, ATI was calculated like EBITDA, but since 2022, the add-back of depreciation and amortization has expired, increasing tax liabilities for higher-leveraged taxpayers.

To mitigate or eliminate the limitations, several strategies are available:

Small Business Exception

Businesses with average annual gross receipts of less than $30 million in 2024 may qualify for an exception under Sec. 163(j)(3), although aggregation rules may apply for related businesses.

Real Property Trade or Business (RPTOB) Election

Real property businesses, such as those involved in development, construction, or leasing, may elect to opt out of the interest deduction limitation, though they must switch to an alternative depreciation system and forgo bonus depreciation.

Self-Charged Interest

For partner loans to partnerships, the final 2021 regulations offer some relief by allowing certain interest expense allocations back to the lending partner.

Capitalization Strategies

Taxpayers can capitalize interest on certain properties including inventories, reducing their business interest expense. This applies after any required interest capitalization under Sec. 263A.  This allows for elective capitalization of certain costs, like interest, improving timing for deductions.

Buy vs. Lease Considerations

Taxpayers must weigh the benefits of leasing versus buying assets, considering both tax and financial reporting. With changes to depreciation and interest deduction limits, capital leases (now finance leases under GAAP) might be less attractive than before, as operating leases may allow for more flexible deductions.

Overall, the Sec. 163(j) limitation presents challenges but also opportunities for strategic tax planning, particularly in choosing between exceptions, capitalization, or restructuring to optimize deductions.
