For small-business owners in Hilo, understanding the rules surrounding business interest expense deductions is crucial for effective tax planning. One important section of the Internal Revenue Code (IRC) that addresses this is IRC Section 163(j), which outlines the limitations on the deduction for business interest expenses.

What is Business Interest Expense?

Business interest expense refers to the interest paid on loans or debt that is used for business purposes. This can include loans taken out to purchase equipment, finance inventory, or cover operational costs. Understanding how much of this interest can be deducted on your tax return is vital for maintaining cash flow and reducing overall tax liability.

Limitations on Business Interest Expense Deductions

According to IRC Section 163(j), there are specific limitations on how much business interest expense can be deducted. Generally, the deduction is limited to the sum of:

• Your business interest income for the year.
• 30% of your adjusted taxable income (ATI) for the year.

Adjusted taxable income is calculated without regard to non-business income, business interest expense, and the deduction for qualified business income.
