In your farming business, you are likely to acquire depreciable property such as buildings or equipment. Since this property wears out or becomes obsolete over time, you can deduct the cost of each item over a period of several years in an annual deduction known as the capital cost allowance (CCA). For example, before recent changes to the rules, you would receive half of the 30 per cent CCA in the first year after purchasing a Class 10 asset (e.g., a self-propelled vehicle). If you bought a tractor that cost $100,000, you would receive a $15,000 write-off in the first year. In subsequent years, that 15 per cent would increase to 30 per cent of the remaining balance.
