Voluntary Disclosure to CBSA: Coming Clean Before the Verification Letter Arrives

A voluntary disclosure to CBSA lets an importer correct customs non-compliance before CBSA identifies it through verification. If accepted, it can waive applicable penalties and reduce specified-rate interest, although the underlying duties, taxes, and applicable interest still have to be paid.

Timing is critical: once CBSA makes contact on the same issue, the disclosure may no longer qualify as voluntary. For importers that uncover classification, origin, valuation, or reporting errors, acting before the verification letter arrives can materially reduce the cost of correction.

What the Voluntary Disclosures Program Waives, and What It Never Will

The Voluntary Disclosures Program is discretionary relief, not an appeal. When a disclosure tied to imported commercial goods is accepted as valid, CBSA waives the administrative monetary penalties that would otherwise attach to the late or incorrect corrections, and where interest would run at the specified (higher) rate, reduces it to the prescribed rate. For non-commercial casual goods, CBSA may waive interest in full and decline to act against the goods or person. That is the whole of the relief: penalties gone, interest softened.

What the program never touches is the underlying revenue debt. You still owe every dollar of duties, GST, and Special Import Measures Act (SIMA) duties on the affected entries, plus prescribed-rate interest on commercial goods. Per CBSA Memorandum D11-6-4, the program is not a vehicle for clients to intentionally avoid legislated obligations, and it grants no immunity from prosecution for conduct such as fraud or intentional evasion. It also cannot waive penalties or interest imposed by other government departments, such as export-permit authorities, and certain enforcement actions, including terms of release on seized goods and amounts demanded on ascertained forfeitures, sit outside the relief entirely.

For a compliance team, the framing is simple: a valid disclosure buys penalty and interest relief and lowers enforcement risk on the goods, but it does not rewrite what you owe or buy a pass on serious misconduct. The strategic logic mirrors the prior disclosure to CBP playbook: come forward, cap the downside, keep the initiative.

The Four Conditions for a Valid Disclosure

CBSA sets explicit conditions, and a disclosure has to satisfy all of them for a delegated officer to treat it as voluntary. Miss one and the officer can decline relief and open verification instead.

1. It has to be voluntary

The client initiates the disclosure, not a prompt from CBSA or another authority acting on the same goods or issue. A submission is not voluntary once an officer has informed the client, in any manner, that goods are being referred, or have been referred, for examination.

2. It has to involve a penalty

The situation must carry the potential imposition of a penalty and/or specified-rate interest, or potential action against the goods or the person. If nothing was at stake, there is nothing to relieve.

3. It has to be complete

The disclosure covers all incidences of non-compliance across defined lookback periods, not a convenient slice. For trade-program errors (origin, tariff classification, value for duty), that means every affected entry over the reassessment window, typically up to four years. For failures to report or account for the same or similar goods, it reaches back six years prior to the disclosure, and export-reporting disclosures cover six prior years plus the current year.

4. It has to be non-repetitive

Except where the disclosure is made simply to comply with Section 32.2, CBSA may deny relief if a previous disclosure was already granted for the same compliance issue. Alongside this, the client has to explain how the non-compliance happened and how it has been corrected, or what controls now reduce the risk of recurrence.

Completeness is where most disclosures fail before they are read. A schedule that stops at the transactions you noticed first, while the same misclassification runs across a product family or several years of entries, reads to CBSA as incomplete, which invalidates the disclosure and leaves the undisclosed errors exposed to full enforcement.

Why the Verification Letter Is the Deadline That Decides Everything

The enforcement clock is why the program rewards speed. A disclosure is not voluntary if it is made after an officer has informed the client, in any manner, that goods are being referred or were referred for examination. For trade-program verifications, the bright line is the verification notification letter. You remain eligible to apply right up until that letter is issued, and you stay eligible even if you already know your goods sit on CBSA's verification priority list. Being on the list is not a contract. The notification letter is.

Once CBSA issues a notification letter for a given program and period, a disclosure on that same program and period is normally no longer treated as voluntary. The correction obligation does not vanish; you still have to fix the declarations, but the penalty and interest relief is gone. That single sequencing point decides whether the same corrections cost you duties alone or duties plus penalties plus specified-rate interest.

Two carve-outs widen the window more than most importers assume. A Canada Revenue Agency tax audit that happens to include imported goods does not preclude a voluntary disclosure for customs non-compliance under Section 32.2. And a verification on one trade program does not block a disclosure on other programs for the same or similar goods, or on issues beyond that verification's scope. A classification verification, for instance, does not close the door on disclosing a separate valuation error.

How Voluntary Disclosure Backstops the Section 32.2 Correction Duty

Section 32.2 of the Customs Act puts a self-assessment duty on importers. Once you have reason to believe a declaration of origin, tariff classification, or value for duty is incorrect, you must file a correction within 90 days, whether the adjustment produces an amount owing or is revenue-neutral. That duty exists whether or not CBSA contacts you.

Reason to believe can arise from specific information, clear legislative provisions, CBSA decisions or rulings, court decisions, supplier notices, or audit reports that objectively indicate the declaration may be wrong. The obligation covers the same and similar goods and normally ends four years after the goods were accounted for.

From there, timing creates two paths:

• If you are still within the 90-day window: File the correction under Section 32.2. You are meeting the statutory correction obligation, so penalties should not normally apply, although interest on additional amounts may still be payable.

• If the 90-day window has passed: Voluntary disclosure becomes relevant. Memorandum D11-6-6 allows CBSA to treat late adjustments as voluntary disclosures and consider relief from penalties and specified-rate interest.

The program also applies where goods were imported but never reported. In that case, there is no earlier Section 32.2 correction to make late; the disclosure itself becomes the mechanism to report the goods, pay the duties and taxes, and seek relief from non-reporting penalties.

In short, voluntary disclosure acts as a backstop once the normal self-correction window has been missed. The obligation to correct remains, but coming forward before CBSA acts can reduce the resulting penalty and interest exposure.

Filing a Disclosure Before CBSA Contact: The Sequence

Preparing a defensible disclosure is a scoping and documentation exercise before it is a submission. The following sequence takes you from a discovered error to a filed request in the CARM Client Portal.

1. Identify the error and pin the reason-to-believe date: Confirm what went wrong, whether origin, tariff classification, value for duty, GST coding, or unreported imports. Then fix the date you first had specific information that made the error apparent, the supplier notice, ruling, or audit report, because that date drives your correction deadlines and tells you whether you are already late.

2. Scope the full error period: Identify every incidence of non-compliance across the reassessment window, usually up to four years from the accounting date for trade-program issues, and back six years for failures to report or account for the same or similar goods. A systematic review of the entry history, rather than the entries you happened to notice, is what keeps the disclosure complete. A tariff audit engine is built to sort a duty history by program and flag which entries carry the recurring error.

3. Quantify duties, taxes, and interest: Build a transaction-level schedule showing corrected HS codes, origin determinations, values for duty, duty rates, SIMA duties, and GST status for each affected import, then total the duties and GST owing. CBSA expects you to take all steps necessary to return to compliant status, which includes full payment of duties, taxes, and prescribed-rate interest on commercial goods.

4. Confirm you are past the 90-day window: If the reason-to-believe date is less than 90 days old and you can finish the corrections in time, file routine accounting adjustments under Section 32.2 without invoking the program. Once more than 90 days have elapsed, your corrections are late, and you frame them as a voluntary disclosure request.

5. Assemble the disclosure package: Include client identification (business number, legal name, books-and-records address, contacts), the disclosure details (nature of the non-compliance, error period, a summary of all affected transactions, Canadian-dollar amounts for duties, SIMA duties, GST, and other taxes, and how the error was discovered), a description of the corrective measures now in place, and a signed declaration that the information is true and complete.

6. Submit through the CARM Client Portal: In the CARM Client Portal, generate a case number, then upload the request letter and supporting documents under it, labeled as a voluntary disclosure case request. Late Section 32.2 corrections are filed as accounting adjustments, which generate Statements of Adjustment and prescribed-rate interest assessments. Importers are already set up through CARM registration and onboarding file inside the same portal they use for daily accounting.

7. Pay the assessment and manage cash flow: Pay the assessed duties and prescribed-rate interest within the time stated on the adjustment or account. Interest relief is discretionary, and any refunded interest itself earns prescribed-rate interest when returned. If a lump sum is not workable, you can arrange a payment schedule with CRA Collections for commercial goods.

Mistakes That Turn a Disclosure Into an Invitation to Audit

The protection a disclosure offers depends on scoping, completeness, and genuine remediation. The recurring failures below cost importers the relief they came for.

Disclosing partially

Limiting the submission to a narrow set of transactions while similar goods or issues over the four-year and six-year windows go unmentioned. CBSA treats incomplete disclosures as invalid, so clients lose relief and still face verification and penalties on whatever was left out.

Understating the error period

Going back only to the date you discovered the problem, rather than the full reassessment period tied to the original accounting dates and the four-year limit in Section 32.2. The discovery date is when your clock started; it is not where the exposure begins.

Filing after CBSA has made contact

Waiting until after a verification notification letter, a directed-compliance letter, or an examination notice arrives. CBSA then reads the submission as prompted rather than voluntary and can proceed with full enforcement.

Treating a broker error as the broker's problem

Assuming a customs broker will absorb or quietly fix the issue. CBSA holds the importer of record responsible for corrections and disclosure, even where the broker filed the original entries.

Not fixing the process that caused it

Skipping the HS databases, valuation policies, supplier-origin controls, and internal-audit routines that prevent recurrence. CBSA can revisit an importer's compliance and may treat repeated issues as grounds to deny relief on a future disclosure.

That last point is where automation earns its place, because a disclosure is only as complete as the review behind it. One international trade consultant and former customs auditor, after putting Gaia's classification engine to work, described the shift plainly: "This is such an incredible product. I was always the one who didn't believe in AI. I believe in this so much now." A former auditor's endorsement is telling, because the completeness a valid disclosure demands is exactly the sweep an auditor would run against you.

Where Disclosures Are Won: Getting Canadian Classification Right the First Time

Most voluntary disclosures trace back to a tariff classification that was wrong for years before anyone noticed, so the surest way to shrink your disclosure exposure is to classify Canadian entries correctly the first time. Origin, valuation, and HS codes carry different rules on the Canadian side than under the US HTS, and a code that is correct for a US entry can still be wrong for CBSA. Building that accuracy in from the start, as tariff classification in Canada increasingly allows, keeps a reason-to-believe trigger from ever forming, and it is a far cheaper posture than scoping four years of corrections under deadline pressure. Coming clean before the verification letter arrives is the right move once an error has happened. Not creating the error is better.

Gaia's Tariff Classification platform helps importers classify products consistently across Canadian and U.S. customs regimes, validate supporting data before filing, and identify classification risks before they become disclosure or audit issues.

Frequently Asked Questions 

Can I still file a voluntary disclosure if my goods are on CBSA's verification priority list?

Yes, being on CBSA's verification priority list does not prevent a voluntary disclosure. The window remains open until CBSA issues a verification notification letter for the relevant program and period. 

Does a CRA tax audit close the door on a customs voluntary disclosure?

No, a CRA tax audit and a CBSA customs voluntary disclosure are separate processes. You can still make a customs disclosure for classification, origin, or valuation errors, provided CBSA has not already started a verification on the same issue. 

Can I be prosecuted even after CBSA accepts a voluntary disclosure?

Yes, in serious cases involving fraud or intentional evasion. The Voluntary Disclosures Program can reduce penalties and certain interest, but it does not provide immunity from prosecution where criminal enforcement is warranted. 

Is my customs broker responsible for filing the disclosure?

No, the importer of record remains legally responsible for correcting customs declarations and filing a voluntary disclosure. Even if a broker submitted the original entries, the compliance obligation stays with the importer. 

What if I cannot pay all the duties and interest at once?

CBSA expects duties and interest to be paid within the required timeframe. If immediate payment is not practical, commercial importers may be able to arrange a payment schedule with CRA Collections, subject to the applicable requirements.
