How do I claim gas for work

Hi there! 

You can deduct your motor vehicle expenses if you meet all of the following conditions:

1. You were normally required to work away from your employer's place of business or in different places
2. Under your contract of employment, you had to pay your own motor vehicle expenses. You are not considered to have paid your own motor vehicle expenses if your employer reimburses you or you refuse a reimbursement or reasonable allowance from your employer
3. You did not receive a non-taxable allowance for motor vehicle expenses. Generally, an allowance is non-taxable when it is based solely on a reasonable per-kilometre rate
4. You keep with your records a copy of Form T2200, Declaration of Conditions of Employment, which has been completed and signed by your employer

The types of expenses you can deduct include:

• fuel (such as gasoline, propane, and oil) and electricity
• maintenance and repairs
• insurance
• licence and registration fees
• capital cost allowance
• eligible interest you paid on a loan used to buy the motor vehicle
• eligible leasing costs
