McQuinn Corp. started operations in 20X5. The company acquired equipment in the first year for a price of $420,000. The equipment will be depreciated for accounting purposes over three years on a straight-line basis (with a full years depreciation in the year of acquisition). For determining income tax payable, the company can deduct one-half of the purchase cost as CCA in the first year, one-third in the second year, and one-sixth in the third year.

The companys 20X5 startup was successful, and in 20X6 the company bought identical equipment for $420,000. In 20X7, a third set of equipment was acquired for $426,000. The pattern of depreciation and CCA is proportionately the same for each acquisition. McQuinns tax rate is 40%. The companys management plans to continue the same level of investment for the foreseeable future, as long as the company remains profitable.

Required: 8 Marks

1. Determine the temporary difference relating to the tax versus accounting bases of the equipment (i.e., CCA versus accounting depreciation) for each year, 20X5 through 20X7. What is the accumulated balance of the temporary difference at the end of each year?

2. What is the balance of the deferred income tax account at the end of each year? Indicate if the year end balance is a debit or a credit

3. What will happen to the accumulated temporary differences and deferred income tax if McQuinn continues to maintain its current level of investment in equipment, replacing each asset as it comes to the end of its useful life?
