## Overview of the Voluntary Disclosures Program (VDP)
The Voluntary Disclosures Program allows taxpayers to **correct unintentional tax errors or omissions** without facing full penalties. It’s ideal for those who have made mistakes in filings, missed income, or claimed ineligible deductions. Up until now, eligibility has been limited in some cases—but that changes soon.

## Key Changes Effective October 1, 2025
- **Increased eligibility**: Those who have received educational letters or communications from CRA about possible non-compliance may now use the program, so long as they aren’t under audit or investigation.

- **Updated relief levels**:
* **Unprompted applications** (before any CRA communication): up to **75% relief on interest** and **100% penalty relief**. ([canada.ca](https://www.canada.ca/en/revenue-agency/news/newsroom/tax-tips/tax-tips-2025/mistake-on-taxes-changes-voluntary-disclosures-program.html?utm_source=openai))
* **Prompted applications** (after receiving a compliance communication): up to **25% relief on interest**, with up to **100% penalty relief**.

- **Simplified process**: Easier language, fewer barriers, more user-friendly forms. Docs now require last 10 years of foreign income/assets, last 6 years of Canadian income/assets, etc. GST/HST info uses the most recent 4 years.

## What This Means for Taxpayers
- Individuals or businesses who missed income disclosure—say, foreign rental income, investments abroad, or side gig income—can come forward now under these better terms.
- If you received CRA letters or notices or suspect you might be under review later, begin preparing your disclosure—starting before audits intensify.
- Use the time to gather documents: past slips, bank statements, international forms.
## Practical Steps to Use the VDP
1. **Assess** whether you qualify: check your communication history with CRA; ensure you aren’t already under audit or investigation for the same issue.
2. **Estimate amounts owing**, interest, penalties—all necessary for full disclosure.
3. **Prepare documentation**: foreign income/assets for past 10 years; Canadian income/assets 6 years. Have records of deductions claimed, etc.
4. **Submit the disclosure** using CRA’s guidance—clearly mark it as VDP. Pay what’s owing or set up arrangements. Relief is only granted if full payment (or arrangements) in place.
## Example Scenario
Maria worked part-time and did freelance gigs online. She forgot to report some international digital work income over the last 3 years. On receiving an “educational letter” from CRA, she now qualifies for the prompted VDP. She estimates tax owing, corrects omissions, pays what she owes; under VDP she gets up to 25% relief on interest and 100% penalty relief—better terms than before.
## Important Cautions
- If CRA already audited the issue, VDP is **not available**.
- Intentional misreporting or egregious non-compliance still disqualifies.
- Use accurate valuations and inclusive reporting—over or under-estimating can lead to rejection.
Correcting past mistakes now under the improved VDP can give peace of mind and avoid bigger issues down the line. With the changes coming October 1, 2025, it’s time for those who could benefit to take action.
