Have you discovered an unfiled Quebec return, omitted income, unremitted sales tax or foreign property that should have been reported? Revenu Québec’s voluntary disclosure program may, in some circumstances, allow the situation to be corrected before an enforcement action begins.
A disclosure does not erase the tax owing and acceptance is never automatic. It should be prepared as a complete compliance file covering the affected years, facts, calculations, records, payment and an explanation of the omission.
How a voluntary disclosure differs from an ordinary adjustment
A routine adjustment may be enough when a recent error is discovered and no significant penalty is involved. Voluntary disclosure is generally considered for failures that may expose the taxpayer to penalties, interest or more serious enforcement measures.
The application must be voluntary. If an audit, formal demand, investigation or other enforcement action has already identified the issue, access to the program may be affected. Review the full correspondence history before submitting anything.
Submit a complete and consistent file
The disclosure generally has to cover all relevant facts and affected years. Selecting only favourable years or omitting a known source of income undermines the credibility of the application and can lead to refusal.
Returns, schedules, slips, sales-tax calculations, bank records and foreign documents should be reconciled. If records are incomplete, estimates should be reasonable, explained and updated when better information becomes available.
- Timeline of the error and its discovery.
- Years and Quebec tax statutes affected.
- Tax calculations requiring correction.
- Payment capacity or a realistic proposal if a large balance remains.
Coordinate Revenu Québec and the CRA
The same facts can have provincial and federal consequences. Omitted foreign income, an unreported corporation, business activity or sales tax may require separate applications with different criteria and forms.
Do not assume that a disclosure filed with one authority automatically corrects the other file. See our page on voluntary disclosure of foreign assets and our article on the federal CRA program.
Estimate the real cost of becoming compliant
Even when an application is accepted, the underlying tax remains payable. The relief from penalties and interest depends on the applicable program and the authority’s decision. The possible balance should therefore be modelled before filing.
A well-prepared disclosure reduces uncertainty, but it does not guarantee a particular result. Current practices also need to be corrected: bookkeeping, filing forms, withholding, sales-tax remittances and record retention.
Act before enforcement begins
When an omission is discovered, first preserve the records and establish the facts. A rushed and incomplete filing can eliminate options that should have been reviewed. Our tax representation service can assist when an authority has already contacted you.
Impôts Ici can assess eligibility, reconstruct the affected years and coordinate the Quebec and federal processes. To discuss the file confidentially, contact our team.
