Incorporated or Not? What Every New Entrepreneur Must Know

The hidden liabilities, real tax advantages, and the honest answer to: "Should I incorporate?"

Every week, we meet new entrepreneurs in the greater Montreal area who are running their businesses without fully understanding the legal and tax framework around them. Some are paying too much in taxes. Others believe their corporation fully shields them from personal liability — until it doesn't. And many are simply unsure whether to incorpor

ate at all.

This blog post is designed to give you a clear, honest picture of what incorporation really means in Canada and Quebec — its genuine benefits, its surprising limitations, and the situations where staying unincorporated actually makes more sense.

Let's start with the most common misconception we hear.

Part 1: The Basics — Proprietorship vs. Corporation

What Is a Sole Proprietorship?

A sole proprietorship is the simplest business structure. There is no legal separation between you and your business. You earn income, you pay tax on it personally, and you are personally responsible for every obligation your business creates — debts, contracts, lawsuits, and tax obligations.

What Is a Corporation?

A corporation is a separate legal entity from its owner(s). It files its own tax returns, enters contracts in its own name, and — in many circumstances — its debts and liabilities belong to the corporation, not you personally. However, as you will read below, this protection is not absolute.

✅  Sole Proprietorship	🏢  Corporation
Simple to set up — no registration required beyond business name	Must be incorporated federally or provincially
No corporate tax returns or annual filings	Separate corporate tax return (T2) required annually
Business losses offset personal income immediately	Lower tax rate on active business income (12.2% in QC up to SBD limit)
Full control — no shareholders or directors obligations	More complex governance (directors, resolutions, minute books)
All profits taxed at personal rates (up to ~53%)	Income splitting and dividend planning opportunities
Personal liability for all business obligations	Limited liability in most (but not all) situations
No cost to wind down	Dissolution process required; legal and accounting costs

Part 2: The Real Tax Advantages of Incorporation

One of the most compelling reasons to incorporate is the tax deferral opportunity. Here is how it works in Quebec:

The Small Business Deduction (SBD)

Canadian Controlled Private Corporations (CCPCs) benefit from a significantly reduced tax rate on the first $500,000 of active business income. In Quebec, this combined federal-provincial rate is approximately 12.2% — compared to a top personal marginal rate that can reach 53.31% for high earners.

This creates a powerful tax deferral: money earned inside the corporation and left there is taxed at ~12.2% instead of your personal rate. You defe

r the personal tax until you choose to pay yourself through salary or dividends — which you can time strategically.

Illustration: The Deferral Advantage

Suppose your business earns $200,000 in profit above your personal needs.

As a sole proprietor: you pay ~$90,000+ in personal income tax immediately.

As a corporation: the corporation pays ~$24,400 in corporate tax, leaving ~$175,600 available to reinvest, grow, or invest inside the corporation.

The difference funds your business growth, not the government — at least until you draw the money out.

Income Splitting Opportunities

A corporation allows you to pay dividends to family members who are shareholders (subject to the Tax on Split Income — TOSI — rules). When done correctly and within CRA's guidelines, this can significantly reduce your overall family tax burden.

Lifetime Capital Gains Exemption (LCGE)

When you sell shares of a qualifying small business corporation, you may be eligible for the Lifetime Capital Gains Exemption — currently over $1 million in Canada (indexed to inflation). This exemption is only available to shareholders of corporations. Sole proprietors selling business assets directly do not qualify.

Salary vs. Dividend Flexibility

As a shareholder-employee of your corporation, you can choose how to extract income — through salary (which creates RRSP room and is CPP/QPP-deductible) or dividends (which receive preferential tax treatment at the personal level). The optimal mix depends on your personal situation, and your CPA should help you determine this each year.

Part 3: The Surprising Limits of Corporate Liability Protection

The Biggest Misconception We Encounter: "My business is incorporated, so I'm protected from personal liability."

This is partially true — and dangerously incomplete. There are several critical situations where incorporation does NOT provides personal protection, such as sales taxes and deduction at source or payroll taxes not remitted to Revenu Quebec and CRA by the corporation.

1. Sales Taxes (GST-HST/PST) — You Are Always Personally Liable

This surprises almost every business owner we speak with. Under the Excise Tax Act and Quebec's Tax Administration Act, if your corporation fails to remit GST/QST it has collected, the CRA and Revenu Québec can pursue the directors personally for 100% of the unremitted amounts — including interest and penalties.

The liability arises because GST-HST/PST is a trust — you collect it on behalf of the government. It is not your money. If the corporation collapses or runs out of funds and those amounts were not remitted, you personally owe them.

Director Liability for GST/QST: What the Law Says

Under Section 323 of the Excise Tax Act and Section 24.0.1 of Quebec's Tax Administration Act:

• Directors of a corporation are jointly and severally liable for unremitted GST/QST.

• This liability cannot be avoided simply by ceasing to be a director after the fact.

• A director can only avoid liability by proving due diligence — i.e., that they took active steps to prevent the failure.

• Revenu Québec has up to 2 years from the date a director resigns to assess them personally.

2. Payroll Source Deductions — Same Personal Exposure

Just like GST/QST, amounts deducted from employee paycheques (federal and provincial income tax, QPP contributions, EI premiums) are held in trust for the government. If your corporation fails to remit these amounts, directors are personally liable.

Under the Income Tax Act (Section 227.1) and Quebec's equivalent provisions, the personal liability for unremitted payroll deductions includes the full outstanding balance, plus interest and penalties. There is no limit and no corporate shield.

Real-World Scenario

A contractor incorporates their business, hires two employees, and falls behind on payroll remittances during a slow quarter. The corporation eventually winds down. Two years later, they receive a personal assessment from CRA and Revenu Québec for $28,000 in unremitted source deductions and GST — plus interest.

The incorporation offered no protection whatsoever for these amounts.

3. Personal Guarantees

When a small corporation applies for a business loan, line of credit, or commercial lease, the bank or landlord will almost always require a personal guarantee from the owner(s). By signing this, you voluntarily waive the corporation's liability shield for that specific obligation.

Many entrepreneurs sign these without fully appreciating the consequence: if the corporation cannot pay, the lender or landlord comes after your personal assets — your home, savings, and investments.

4. "Piercing the Corporate Veil"

Courts can and do set aside corporate limited liability in cases of fraud, personal wrongdoing, commingling of personal and corporate funds, or where the corporation is used as an alter ego. This is rare but very real — and another reason why maintaining proper corporate formalities (separate accounts, proper bookkeeping, resolutions, and minute books) is not optional.

Part 4: What Incorporation Does Protect You From

Despite the above limitations, incorporation does provide meaningful protection in many circumstances:

• Commercial debts to suppliers, vendors, or service providers — if you have not personally guaranteed them

• Contract disputes where the corporation is the contracting party

• Business-related lawsuits (e.g., a client suing for a failed project) — subject to the corporate veil being respected

• General business liabilities from operations

• In some professions, protection against malpractice through a professional corporation structure (note: Quebec regulated professions have specific rules)

The key takeaway: incorporation provides a real but limited liability shield. It works best for general commercial risk. It does not protect you from tax obligations that arise from your role as a director — particularly GST/QST and payroll remittances.

Part 5: When Does Incorporation Make Sense?

Not every business should incorporate — especially not right away. Here is a practical framework to guide the decision:

✅  Incorporation Likely Makes Sense When...

• Your business generates consistent net profit significantly above your personal living needs (general threshold: $50,000+ in retained earnings)

• You operate in a field with meaningful liability risk (construction, consulting, tech, health services)

• You want to build a business you intend to sell — the LCGE can shelter over $1M in gains

• You have family members who could legitimately participate in ownership (income splitting)

• You want to attract investors or partners in the future

• You are planning to grow and hire employees

• Your business contracts with other corporations who prefer or require it

⚠️  Incorporation May NOT Be the Right Move Yet When...

• Your business is in its early stages and not yet consistently profitable

• You need all your business income to fund your personal lifestyle — the deferral advantage disappears when you extract everything

• You are in a profession where Quebec requires specific corporate structures (e.g., notaries, physicians — check with your professional order)

• Your business generates losses — these are trapped in the corporation and cannot offset your personal income

• The added compliance costs (corporate returns, bookkeeping, minute books, legal fees) outweigh the tax savings at your income level

Part 6: Risks of Staying Unincorporated — What Sole Proprietors Must Understand

Sole proprietorship is not inherently bad — for many small businesses, it is the right structure. But you must enter it with clear eyes about the risks:

Risk	What It Means for You
Unlimited personal liability	A client lawsuit, supplier dispute, or business failure can reach your personal bank accounts, home equity, and savings with no limit.
High personal tax rates	All net business income is taxed at personal rates — up to 53.31% in Quebec. There is no deferral opportunity.
No income splitting	You cannot share business income with a lower-income spouse or adult children to reduce total family taxes.
No LCGE on sale	When you sell your business or its assets as a proprietorship, you do not qualify for the Lifetime Capital Gains Exemption.
Harder to raise capital	Investors and institutional lenders generally prefer dealing with incorporated entities.
Succession is complex	A sole proprietorship does not survive the owner. Transferring the business requires selling assets, not shares.

Part 7: If You Are Incorporated — Critical Compliance Obligations

If you have already incorporated or are about to, here are the non-negotiable compliance responsibilities that protect your business — and your personal assets:

Remittances Are Sacred

Never be late on GST/QST or payroll remittances. If cash flow is tight, contact CRA and Revenu Québec proactively to arrange a payment plan. Ignoring remittances creates personal director liability and accumulates penalties and interest rapidly.

Keep Corporate and Personal Finances Completely Separate

Maintain a separate corporate bank account and credit card. Never commingle funds. Pay yourself through formal salary or dividend declarations — not by dipping into the corporate account for personal expenses. Commingling is one of the most common triggers for courts piercing the corporate veil.

Maintain Your Minute Book

Your corporation is legally required to maintain a minute book containing the articles of incorporation, shareholder register, director register, and annual resolutions. This is not optional — and many entrepreneurs discover their minute book is years out of date when they try to sell or refinance.

File Your Corporate Tax Returns on Time

Corporate tax returns (T2 and Quebec CO-17) are due 6 months after your fiscal year-end. If your corporation has a balance owing, it is due 2 months after year-end (3 months for some CCPCs). Missing these deadlines triggers interest and penalties — and can affect your SBD eligibility.

The Bottom Line: Structure Strategically, Not by Default

Far too many entrepreneurs choose their business structure by accident — they either incorporate because it sounds professional, or they stay unincorporated because it seems simpler. The right answer depends on your personal income level, risk profile, growth plans, industry, and family situation.

The most expensive mistake we see? Business owners who wait too long to incorporate (missing years of tax deferral) — or who incorporate and then fail to comply with their remittance obligations, creating personal tax debt that never goes away.

Our Recommendation
