You find an old mistake and suddenly have ten browser tabs open: penalties, forms, relief, letters. The problem grows before you have even decided what needs to be fixed.

Start as if you were standing at a fork in the road. Was the return already filed? Was it never filed? Has CRA contacted you about the same issue? Those three questions come before the name of any program.

This article explains where the Voluntary Disclosures Program, usually called VDP, fits. You will learn what a CRA letter may change, what VDP can and cannot do, and what to bring to a first conversation.

What is VDP, in plain language?

VDP is a CRA relief program for certain older tax errors or missing information. When a person comes forward with a qualifying correction, CRA reviews the application and decides whether to give relief.

If CRA accepts the application, it may remove penalties and reduce part of the interest connected with the disclosure. The tax itself still has to be paid, along with any interest that is not relieved.

The current VDP rules apply to applications received on or after October 1, 2025. That matters because older articles may describe a program that no longer works the same way.

Key idea

VDP may reduce penalties and some interest. It does not erase the tax itself.

Do you need VDP at all?

Not every old mistake belongs in VDP. First identify which of these three situations looks closest to yours:

  • A return was filed, but something was missing or wrong. CRA has a normal process for changing an assessed return.
  • A return was never filed. It may simply need to be filed late in the usual way.
  • The mistake is old, may involve tax, penalties, or interest, and the VDP conditions may fit. This is the point for a VDP review.

What changes if CRA has already contacted you?

A CRA letter matters, but the word “letter” is not enough to decide the route. Bring the full document and look at what it says about the same issue you want to correct.

General educational information may still leave an application in the unprompted category. A letter that identifies a specific problem or gives a deadline may make the application prompted, which can change the relief. If an audit or investigation has already started about the information being disclosed, the application is not considered voluntary.

Do not ignore a response date while researching VDP. The wording, subject, and stage of the contact need to be reviewed together.

What does CRA check before VDP can help?

You do not need to turn yourself into a VDP specialist. It is enough to understand why CRA asks for a complete picture.

  • the application comes before an audit or investigation into the same information
  • the relevant facts and documents are included
  • the mistake may lead to penalties or interest
  • the information is at least one year past its filing due date
  • the estimated tax is paid, or a payment arrangement is requested and remains subject to CRA approval

What should you gather before asking for help?

Start with a small folder, not a finished application. Write down the years involved and one sentence about what may have been missed.

Add every CRA letter or notice, the returns you still have, and any records connected with the missing income or information. If documents are gone, list what is missing instead of guessing the numbers.

That is enough for a first review. The goal is to choose the correction road and identify the next records to recover.

What happens in the first conversation with Anytime Accounting?

The initial consultation is free. Anytime Accounting can review the CRA contact, map the affected years, and separate information that was already correct from what may need to be fixed.

The first useful result is a correction plan: which road may fit, what documents still matter, and what should happen before anything is sent. If VDP looks relevant, the next step is a full eligibility and completeness review — not a promise that CRA will grant relief.

Bring the letter and the years. We can start there.

You do not need to choose VDP alone or prepare a perfect file before contacting us. In a free initial consultation, we can map the correction route and give you a clear list of next steps.

FAQ

No. A filed return may use CRA's normal change process, and an unfiled return may need an ordinary late filing. VDP is a separate relief route with its own conditions.

No. General information, a letter about a specific issue, and an audit are treated differently. The full letter and its connection to the information being disclosed need to be reviewed.

No. If CRA grants relief, it may remove penalties and reduce part of the interest, but the underlying tax and remaining interest are still payable.

No. Bring the years you know, the CRA letters you have, and the records that survived. A first review can identify what still needs to be recovered before a complete correction is prepared.
