175.1.1. Subject to section 851.22.13.1, where, at any time, a payment is made to a person or partnership by a taxpayer in the course of carrying on a business or earning income from property in respect of borrowed money or on an amount payable for property acquired by the taxpayer, in this section referred to as a “debt obligation”, as consideration for a reduction in the rate of interest payable by the taxpayer on the debt obligation, or as a penalty or bonus payable by the taxpayer by reason of the repayment by the taxpayer of all or part of the principal amount of the debt obligation before its maturity, the payment is deemed, to the extent that it may reasonably be considered to relate to, and does not exceed the value at that time of, an amount that, but for the reduction or the repayment, would have been paid or payable by the taxpayer as interest on the debt obligation for a taxation year of the taxpayer ending after that time,(a) for the purposes of this Part, to have been paid by the taxpayer and received by the person or partnership at that time as interest on the debt obligation, and
(b) for the purpose of computing the taxpayer’s income in respect of the business or property for the year, to have been paid or payable by the taxpayer in that year as interest pursuant to a legal obligation to pay interest,i. in the case of any such reduction, on the debt obligation, and
ii. in the case of any such repayment, where the repayment was in respect of all or part of the principal amount of the debt obligation that was(1) borrowed money, except to the extent that the borrowed money was used by the taxpayer to acquire property, on borrowed money used in the year for the purpose for which the borrowed money that was repaid was used, or
(2) either borrowed money used to acquire property or an amount payable for property acquired by the taxpayer, on the debt obligation to the extent that the property or property substituted therefor is used by the taxpayer in the year for the purpose of earning income therefrom or for the purposes of gaining and producing income from a business.
The first paragraph does not apply where the payment (a) may reasonably be considered to have been made in respect of the extension of the term of a debt obligation or in respect of the substitution or conversion of a debt obligation to another debt obligation or share, or
(b) is contingent or dependent on the use of or production from property or is computed by reference to revenue, profit, cash flow, commodity price or any other similar criterion or by reference to dividends paid or payable to shareholders of any class of shares of the capital stock of a corporation.
