Q: The Nov.19 response to the tax treatment of GIC interest question is not quite accurate.
Most interest received is treated on a cash basis, so on a 1 year GIC a holder must only wait for the issuer's T5.
As for a COMPOUND interest GIC beyond one year, the second part of your response would apply, except it is the onus of the issuer to do the accounting and issue T5s.
