Frequently Asked Questions

What is the difference between a deduction and a credit?

A deduction reduces your taxable income, while a credit directly reduces the amount of tax you owe. Both can help lower your tax liability, but they work in different ways.

Can I deduct all my expenses?

No, only eligible expenses can be deducted. You must keep receipts and records to support your deductions. The Canada Revenue Agency (CRA) will review your claims to ensure they are eligible.

When should I file my tax return?

You should file your tax return by the deadline set by the Canada Revenue Agency (CRA). The deadline is typically April 30 for most taxpayers, but it can vary depending on your situation.

What happens if I don't claim my deductions?

If you don't claim your deductions, you may owe more tax than necessary. The Canada Revenue Agency (CRA) can audit your return and assess additional tax if they find you were eligible for deductions.
