Deductibles are often one of the least understood parts of doing taxes. At worst, people simply ignore them. At best, they let their local tax accountant in Ajax deal with it without giving the subject much more thought. If either of these extremes are the case for you, you’re missing out on great opportunities to lower your taxes even more. Knowing which tax deductions you’re eligible for and how to go about claiming them could save you a lot of money when tax season rolls around.
