The Canadian and Quebec tax systems are founded on a complex web of concepts and rules. This can make preparing a tax return quite challenging, and it is not unusual for tax specialists to find mistakes in their clients’ files. While some of these are minor and have no serious repercussions, others can result in substantial tax adjustments. Fortunately, the tax authorities provide various ways for taxpayers to fix a mistake.

What is the voluntary disclosure program?

Both the Canada Revenue Agency and Revenu Québec have a voluntary disclosure program allowing taxpayers to correct a tax error or omission. These programs are strictly regulated and have several eligibility conditions that limit the situations in which they can be used. This makes it imperative to carefully analyze their respective rules, which differ in several respects.

Taxpayers can also anonymously contact a representative of either tax authority for clarification before submitting an official application. Generally speaking, for an application to be accepted, it must:

  • be voluntarily presented by the taxpayer;
  • include information related to a tax year that is at least one year past the filing due date;
  • include errors or omissions with applicable interest charges and penalties;
  • include all the application’s supporting documents as required by the relevant tax authorities;
  • be accompanied by a payment or a request for a payment arrangement on the estimated amount of tax payable.

Once an application has been accepted, the charges are still payable in full and penalties will generally not be applied. The interest payable may also be reduced, depending on the type of case and the tax authority concerned.

Good to know: With some exceptions, a voluntary disclosure application may be submitted only once.

Can you simply amend a tax return?

Yes. When an error is small or has minimal financial impact, it is often simpler to correct it by filing an amended return. This simpler and less costly option allows you to regularize your situation without going through the entire voluntary disclosure process, which is often cumbersome and requires a considerable investment of time and money.

However, filing an amended return does not lead to reduced penalties or interest, and the tax authorities are not obliged to process it, so it is only accepted at their discretion.

What if the error was discovered during a tax audit?

Sometimes a taxpayer finds an inaccuracy while preparing the documents requested by the authorities during a tax audit. In such cases, it is often better to report the error to the designated auditor right away. Being transparent in this way can lead to a fairer settlement and reduce the risk of additional penalties.

In conclusion: Correct it, but be methodical

Whether you are making a voluntary disclosure, filing an amended return or making a correction during an audit, it is crucial to adopt a structured and well-documented approach. The financial and legal consequences can be considerable, so it is strongly recommended to consult an experienced tax specialist to get the right advice and the best settlement of your case.
