## What’s New for Corporations
CRA recently updated rules affecting **corporate income tax** and related administrative responsibilities:
- From **November 3, 2025**, any registration for a new **Business Number (BN)** or CRA program account must be done **online**. Paper/phone registrations are being phased out. ([canada.ca](https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/corporations/whats-new-corporations.html?utm_source=openai))
- Effective **October 1, 2025**, changes were made to the **Voluntary Disclosures Program (VDP)** to make it easier to apply and understand. This means that entities seeking relief from penalties must be more aware of the updated format.

## Implications for Setting Up or Running a Business
### Business Number (BN) Registration
Having a BN is a first step for tax registration—goods/services tax (GST/HST), payroll deductions, corporate tax, etc.
**Actionable points**:
- Go online to register — ensure your business has access to computers and stable internet.
- Gather required information ahead: business structure (corporation, partnership), ownership details, address, nature of business activities.
- If migrating from phone/paper to online, allow time for system familiarization.
### Voluntary Disclosures Program (VDP)
VDP allows taxpayers (including corporations) to correct past errors or omissions with potential relief from penalties.
**What’s changed**:
- Easier applications; clearer guidance.
- Enhanced eligibility clarity — potential for more entities to qualify.
**Strategies**:
- If past filings may have errors (e.g. missed GST, payroll deductions), consider if VDP applies now with new rules.
- Consult professionals to determine whether the disclosure is “voluntary” (meaning CRA hasn’t contacted you), and ensure corrections include full details.
- Maintain documentation—dates, amounts, prior communications—since CRA may assess the completeness of the disclosure.
## Sample Use Cases
**Use Case 1**: You start a new tech consulting business. You’ll apply online for BN. When hiring employees, you’ll need program accounts (payroll, GST/HST). Doing it online streamlines access and reduces administrative delays.
**Use Case 2**: A small retail corporation discovered they forgot to remit GST for a prior year. Under the new VDP rules, they may be able to correct that error, pay owed tax plus interest, and avoid penalties, provided they meet the updated eligibility criteria. Understanding what “simple” versus “complex” disclosure means under the new regime is key.
## Tips to Optimize Company Structure with New Changes
- **Pick the right type of entity**: Canadian Controlled Private Corporation (CCPC) vs publicly held vs partnership; understand different tax treatments (small business deduction, refundable credits).
- **Keep accurate books from day one**: digital record-keeping aids in accurate BN registration and easier voluntary disclosures if needed.
- **Plan taxable year-ends and filings**: anticipate deadlines for remittances, returns, disclosure windows under VDP.
- **Stay compliance vigilant**: Payroll, corporate income taxes, sales taxes — non-compliance in any area could trigger disclosure or punitive measures.
## Conclusion
Recent changes in how corporations register and how they can self-correct past issues create opportunity. If you're setting up a business—or running one—these changes reduce friction and offer clearer paths to compliance. Being proactive, gathering the right information, and staying updated will help you take full advantage.
