If you use your car for work, you may be able to claim a deduction for car expenses, including car insurance. This includes if you are using your car as a ride-sharing service or as an employee travelling for work. However, you probably use your car for both business and private use. As a result, you need to separate your car expenses so that you don't claim for personal use. An effective way to do this is through a logbook.
If you don't use your car for work, it's unlikely you'll be able to claim car insurance on tax.
