You can deduct certain expenses (including any GST/HST) you paid to earn employment income. You can do this only if your employment contract required you to pay the expenses and you did not receive an allowance for them, or the allowance you received is included in your income.
Most employees cannot claim employment expenses. You cannot deduct the cost of travel to and from work, or other expenses, such as most tools and clothing.
You have to keep records for each year you claim expenses. For more information, see Keeping records.
Repayment of salary or wages - You can deduct salary or wages you reported as income for 2012 or a previous year, if you repaid them in 2012. This includes amounts you repaid for a period when you were entitled to receive wage-loss replacement benefits or workers' compensation benefits. However, you cannot deduct more than the income you received when you did not perform the duties of your employment.
