Voluntary Disclosure vs. Amending Your Return: Which Fits in Canada?

You have found a mistake on a return you filed, or a return you never filed. Before you do anything, you want to know whether a straightforward request to correct the return will do, or whether you need to make a formal voluntary disclosure to the CRA.

The two routes serve different situations. This article explains what the Voluntary Disclosures Program (VDP) is for, the conditions it sets, and the cases where it does not apply, so you can have a more useful conversation with an accountant or lawyer.

This article covers Canadian federal tax law, which applies in every province.

Two routes for two kinds of problem

Amending a return is the ordinary way to fix a filed return. For example, if a principal residence designation was missed, the CRA says to ask it to amend the return for the year of the sale.

The VDP is different. It lets you come forward to correct errors or omissions, such as unreported income or unfiled returns, and if your application is accepted the CRA may give penalty and interest relief and will not refer the disclosed matter for criminal prosecution. The current rules apply to applications received on or after October 1, 2025.

When the VDP conditions point to a formal disclosure

The CRA sets conditions for a valid VDP application. A correction that fits these conditions is the kind the program is designed for:

• The application is voluntary and complete, with all supporting documents.
• It involves interest, penalties or both.
• It includes information that is at least one year past the filing due date.
• It includes payment of the estimated tax owing, or a request for a payment arrangement.

The CRA lists situations that may be eligible, including not reporting or under-reporting income, not reporting foreign income taxable in Canada, and not filing a return that is now a year late. Claiming ineligible expenses is also on that list.

When the VDP is not the right tool

Some situations are generally not eligible. These include applications that produce a refund or no tax or penalties owing, requests for relief on penalties or interest already assessed, applications to make or alter an election, and insolvency for the years involved.

A disclosure is also not voluntary if an audit or investigation has been started against you or a related taxpayer for the information you want to disclose. A CRA letter about a specific issue does not by itself end eligibility, but the application is then treated as prompted, with partial relief, provided you are not under audit or investigation.

If you are not eligible, the CRA points to other options, such as the taxpayer relief provisions. Whether a simple amendment is enough for your facts is worth confirming with a tax professional.

What a VDP application can and cannot give you

Relief depends on whether your application is unprompted or prompted.

An application is generally unprompted if the CRA has not communicated with you about the issue, or if the only contact was a general education letter. It is generally prompted if it follows CRA communication identifying a specific error or setting a correction deadline, or follows third-party information about your non-compliance.

The VDP gives relief on penalties and interest, not on the tax itself, so the tax owing must be paid. The CRA also reserves the right to audit any information in an application whether or not relief is granted.

What to do next

• Write down what was wrong: which return, which year, and whether the CRA has contacted you about it.
• Check whether any CRA letter, audit or investigation already touches the same information.
• Work out whether the correction produces tax owing, a refund, or neither.
• Gather your records for the affected years.
• Ask an accountant or lawyer whether to amend the return or apply under the VDP before you file anything.

Take care with sequencing.
