A business loan repayment may include principal, interest and lender fees. Each component receives different tax treatment, so business owners should check loan statements before preparing a return.
Interest and fees
Is business loan interest tax-deductible in Australia? Interest may be deductible when the borrowed money is used for an income-producing business purpose. Examples may include purchasing trading stock, paying operating expenses or buying equipment used by the business.
Principal repayments
The principal is the original amount borrowed. Repaying it reduces the outstanding debt but does not usually create a deductible expense.
Business owners asking, “Can I claim business loan repayments on tax in Australia?” should separate the principal from interest and eligible fees. Loan statements generally show how much of each repayment was allocated to these components.
The tax treatment of the asset or expense purchased with the loan is considered separately. For example, an asset may qualify for depreciation or another capital allowance even though its loan principal repayments cannot be claimed.
