## Legal Structures Overview
When starting a business in Canada, the choice of **entity type** greatly influences taxes, liability, and growth. Here are the primary structures:
- **Sole Proprietorship:** simplest. You and the business are one legal entity. Profits taxed at your personal rates; full liability.
- **Partnership:** shared ownership and liability. Taxed through partners; limited by income pooling, not by law (unless a limited liability partnership).
- **Corporation (federal or provincial):** separate legal entity. Owners are shareholders. Profits may be retained in the company with lower tax; limited personal liability.

## Tax Implications for Each Structure
| Structure | Tax Rate for Profits | Personal Liability | Compliance / Filing Burden |
|---|---|---|---|
| Sole Proprietorship | Taxed at personal marginal rate | Unlimited (you are personally responsible) | Minimal: one T1 return with added schedules |
| Partnership | Similar to sole proprietor for each partner; depends | Shared liability unless limited | Requires partnership allocation returns; partners file own T1s |
| Corporation | Corporate tax rates; small business rates available | Limited to investment in shares | Must file corporate (T2) returns, maintain corporate records, potentially payroll, GST/HST, etc. |
**Example:** If a small tech business in Ontario earns $150,000 net profit:
- As sole proprietor: taxed fully at personal rates—possibly >30% in combined federal/provincial tax.
- Incorporated and eligible for small business rate (~9% federal + provincial) on the first ~$600,000 of active business income—lower tax on retained profits.
- But corporation faces more rules: separate bookkeeping, corporate filings, payment of dividends, potential double taxation when distributing profits.

## When a Corporation Is the Better Choice
Consider incorporating if:
- You expect profits well above your personal needs, letting you retain earnings in the company.
- You want limited liability or formal structure, possibly for investors.
- You wish to access small business deduction (federal and provincial) for reduced tax rates.

## Planning for Growth & Exit
- **Dividend planning:** When distributing profits, dividends are taxed in hands of shareholders—plan to balance salary vs. dividends for tax efficiency.
- **Capital gains:** Shares held long-term may qualify for preferential treatment—e.g., Lifetime Capital Gains Exemption for QSBC shares (Québec/Canada) if eligible.
- **Succession & sale:** Corporations allow share transfers; sole proprietorships require transfer of assets—often less flexible.

## Action Steps When Setting Up
1. Register your business (provincially and/or federally).
2. If incorporating, obtain Business Number and register for GST/HST if revenue thresholds met.
3. Set up separate business bank accounts and accounting system.
4. Meet payroll obligations if hiring staff.
5. Plan tax filings in advance—both corporate (T2) and personal (T1) if drawing salary or dividends.
**In summary:** Your choice of business entity shapes your exposure to tax, liability, compliance, and business flexibility—selecting the right form early saves money and headache long-term.
