How to Handle Your Tax Return When You’ve Made a Mistake
Tax season can be stressful, and mistakes on your tax return are more common than you might think. Whether you’ve missed a deduction, misreported income, or filed incorrectly, it’s important to address the error quickly. The good news is that you can correct these mistakes and minimize the impact on your finances. If you’ve made a mistake on your tax return, don’t panic. Here’s what you should do next to fix it and ensure you don’t face penalties.

Understand the Types of Mistakes You Can Make
The first step in fixing your tax return is understanding the types of mistakes that can happen. Some common errors include:
Forgetting Deductions or Credits: It’s easy to overlook eligible deductions or credits like student loan interest, charitable donations, or business-related expenses. Missing these can leave you paying more tax than necessary.
Claiming Ineligible Expenses: Many taxpayers accidentally claim expenses they are not entitled to, such as moving costs that don’t meet the eligibility criteria or claiming the wrong type of tax credits.
Misreporting Marital Status: If you’re married or living in a common-law relationship, you need to report your status correctly. Misreporting this can affect benefits like the Canada Child Benefit or GST/HST credits.
Incorrect Income Reporting: If you’ve forgotten to include some income or have entered it incorrectly, it could lead to a higher tax liability or an audit.
These mistakes are common, but they can often be corrected without severe consequences if you act quickly.
How to Correct Mistakes After Filing
If you’ve realized that you made a mistake after submitting your tax return, don’t panic. There are ways to correct it.
File an Adjustment Request
Once you’ve received your Notice of Assessment from the Canada Revenue Agency (CRA), you can request a change to your return. Here’s how to proceed:
Log into your CRA My Account: If you filed your taxes online, you can use the “Change My Return” feature to make adjustments. This is a quick and easy way to correct errors without having to file a new return.
Complete a T1-Adjustment Request: If you filed a paper return, you’ll need to complete the T1-Adjustment Request form and mail it to the CRA with your supporting documents.
Wait for the CRA's Response: Once the CRA processes your adjustment request, you’ll receive a Notice of Reassessment if your change is approved. If it’s rejected, you’ll get an explanation, and you can choose to file an objection if necessary.
Use the Voluntary Disclosure Program (VDP)
If you’ve missed reporting income or need to correct a major error, you may be eligible for the CRA’s Voluntary Disclosure Program (VDP). This allows you to make changes to your return without facing penalties, as long as:
You haven’t already been contacted by the CRA about your mistake.
Your disclosure is complete and includes all the necessary information.
The information is over a year old.
The VDP can help you avoid severe penalties, so it’s worth considering if you’ve made a significant error in your filing.
The Consequences of Leaving Mistakes Uncorrected
Ignoring mistakes on your tax return can lead to some serious consequences:
Penalties and Interest: If you owe more taxes due to an error, the CRA will charge you interest on the unpaid amount. This interest can add up quickly, increasing your overall tax burden.
Delays in Refunds or Benefits: If you’ve underreported your income or claimed incorrect deductions, it could delay your refund or cause your benefits (like the Canada Child Benefit) to be recalculated or suspended.
Risk of Audit: Consistently making mistakes on your tax return can raise red flags with the CRA and potentially trigger an audit.
It’s important to address mistakes as soon as possible to avoid these penalties and complications.
