Choosing the Wrong Business Structure
One of the first decisions you’ll make is selecting the right legal structure. Many business owners jump straight into incorporation without considering whether a sole proprietorship or partnership might be more appropriate at their current stage.
Avoid this by:
- Consulting a legal or financial advisor to assess what’s best for your business goals.
- Considering your tax situation, liability exposure, and growth plans.
-
Picking a Business Name Without a Proper Search
Just because a name sounds great doesn’t mean it’s legally available. Failing to do a proper NUANS (Newly Upgraded Automated Name Search) report can lead to trademark conflicts or forced rebranding down the road.
Avoid this by:
- Conducting a NUANS search before registering your business name.
- Checking domain and social media availability to build a consistent brand.
-
Not Understanding the Difference Between Federal and Provincial Incorporation
Many Canadian business owners incorporate provincially without realizing the limitations on name protection and geographic operation. Others go federal without needing the nationwide reach.
Avoid this by:
- Learning the pros and cons of federal vs. provincial incorporation (see our previous article).
- Choosing based on where and how you plan to operate your business.
-
Failing to Draft a Shareholder Agreement
Even small startups with two or three founders can run into big problems without a shareholder agreement. This document lays out what happens if someone leaves, wants to sell their shares, or disagrees with a decision.
Avoid this by:
- Working with a legal expert to create a custom shareholder agreement early.
- Clearly defining roles, responsibilities, and equity ownership.
-
Not Keeping Up With Corporate Filings
Incorporating isn’t a one-and-done task. Your corporation must file annual returns, keep corporate records up to date, and follow other legal requirements to remain in good standing.
Avoid this by:
- Setting calendar reminders for key filing deadlines.
- Hiring a corporate services provider like MaxPro Financials to stay compliant.
-
Using Personal Accounts for Business Finances
Mixing business and personal finances is a recipe for accounting confusion and possible legal trouble, especially when tax season rolls around or if you face an audit.
Avoid this by:
- Opening a dedicated business bank account immediately after incorporating.
- Keeping clean records of income and expenses from day one.
-
Assuming Incorporation Automatically Grants Licenses
Incorporation gives you legal status—but it doesn’t mean you can start operating immediately. Many industries require additional licenses and permits.
Avoid this by:
- Checking municipal, provincial, and federal licensing requirements based on your business type.
- Consulting local business resource centers or professionals for guidance.
