nectar88, I'm quite sure that interest is only tax deductible if the share you have purchased is paying dividends, or it is reasonable to expect the company will pay dividends in the year the interest is incurred. If the share you have purchased is not paying dividends, or it is not reasonable to think that it will pay dividends in the year the interest is incurred, the interest is added to the cost base of the shares.
That's my reading of it anyway.
