127.6. Where, at any time in a taxation year of a corporation resident in Canada, a person not resident in Canada owes an amount to the corporation, that amount has been or remains outstanding for more than a year and the amount determined under the second paragraph for the year is less than the amount of interest that would be included in computing the corporation’s income for the year in respect of the amount owing if that interest were computed at a reasonable rate for the period in the year during which the amount was owing, the corporation shall include an amount in computing its income for the year equal to the amount by which the amount of interest that would be included in computing the corporation’s income for the year in respect of the amount owing if that interest were computed at the prescribed rate for the period in the year during which the amount was owing exceeds the amount determined under the second paragraph.
The amount to which the first paragraph refers is equal to the aggregate of(a) an amount included in computing the corporation’s income for the year as, on account of, in lieu of or in satisfaction of, interest in respect of the amount owing;
(b) an amount received or receivable by the corporation from a trust that is included in computing the corporation’s income for the year or a subsequent year and that can reasonably be attributed to interest on the amount owing for the period in the year during which the amount was owing; and
(c) an amount that is included in computing the corporation’s income for the year or a subsequent year under section 580 and that can reasonably be attributed to interest on the amount owing for the period in the year during which the amount was owing.
