At what income should I incorporate in Canada?

Most accountants recommend incorporating when your business earns $60,000-$80,000+ in net income that you do not need to live on. Below that, the tax savings from incorporation are minimal. The key benefit comes from leaving money inside the corporation (taxed at ~12.2%) versus personally (taxed at 30-50%+).

How much does it cost to incorporate in Canada?

Initial incorporation costs $1,000-$2,500 (legal fees + filing). Ongoing costs include corporate tax returns ($1,500-$3,000/year), annual filings ($20-$60), a business bank account, and bookkeeping ($100-$300/month). Total annual overhead is $3,000-$6,000.

Can I save tax by incorporating my side hustle?

Yes, but only if you leave profits inside the corporation. The small business tax rate is ~12.2% (federal + provincial) on the first $500,000 of active business income. If you withdraw all profits as salary or dividends, the total tax is roughly the same as personal income tax due to tax integration.

What is the difference between a sole proprietorship and corporation?

A sole proprietorship is you — all income is personal, all liability is personal. A corporation is a separate legal entity with its own tax return, limited liability, and different tax rates. Sole proprietorship is simpler and cheaper; corporation offers tax planning flexibility and liability protection.

Tax Comparison: Sole Prop vs Corporation

Item	Amount
Business income	$100,000
CPP (self-employed, both shares)	-$7,735
Taxable income	~$100,000
Federal + Ontario tax	~$23,000
CPP premiums	~$7,735
Total tax + CPP	~$30,735
Take-home	~$69,265

Corporation (Leave $40K Inside Corp)

Item	Amount
Corporate income	$100,000
Pay yourself salary	$60,000
Corporate tax on remaining $40,000 (12.2%)	$4,880
Personal tax on $60,000 salary	~$10,500
CPP on $60K salary (employee share)	~$3,867
Total tax + CPP	~$19,247
Take-home (personal)	~$45,633
Retained in corp	~$35,120
Tax deferred	~$11,488

The $35,120 retained in the corporation is available for business investment, corporate savings, or future withdrawal at a time when your personal tax rate is lower.

Tax Deferral Advantage

Net Income	Tax as Sole Prop	Tax with Corp (leave 40% in corp)	Annual Deferral
$60,000	$12,000	$9,500	$2,500
$80,000	$18,000	$13,000	$5,000
$100,000	$30,700	$19,200	$11,500
$150,000	$48,000	$30,000	$18,000
$200,000	$68,000	$42,000	$26,000

Deferral is not permanent tax savings — when you eventually withdraw from the corporation, you pay personal tax. But deferral lets the money grow tax-efficiently inside the corp.

Salary vs Dividends

Factor	Salary	Dividends
CPP contributions	Yes (builds CPP retirement)	No
RRSP room	Creates RRSP contribution room	Does not
Personal tax deduction	No	Dividend tax credit

Most common strategy	Pay salary up to RRSP max ($60K-$80K), take rest as dividends
