Should I incorporate my business in Alberta?

Incorporating makes financial sense once your business earns consistently above $60,000–$80,000/year. Below that, the added costs of incorporation (setup $1,500+, annual accounting $2,000–$4,000) often outweigh the tax savings. At higher incomes, the 11% corporate rate vs. personal rates of 25–40%+ creates substantial savings through income deferral and the dividend strategy.

What is the tax rate for a sole proprietor in Alberta?

Sole proprietors pay personal income tax on all net business profit — combined federal and Alberta rates range from 25% (under ~$57K) to 48% (over $220K). They also pay both employee and employer CPP contributions (11.9% on net income between $3,500 and $71,300), adding up to $8,068/year.

What is the small business corporate tax rate in Alberta 2025?

Alberta CCPCs pay a combined 11% on the first $500,000 of active business income: 9% federal (after small business deduction) plus 2% Alberta provincial. Above $500,000 the general rate is 23% combined.

Do sole proprietors have to register for GST?

Yes — once your business earns $30,000 or more in a rolling 12-month period, GST registration is mandatory in Canada. You must collect 5% GST from customers and remit it quarterly. This applies to both sole proprietors and corporations.

What is the salary vs dividend strategy for a corporation?

Many Alberta CCPC owners pay themselves $3,500 in salary (the CPP basic exemption) to maintain a T4 record without triggering CPP contributions, then take remaining corporate after-tax income as non-eligible dividends. At lower income levels (under ~$60K), dividends from a corporation can be very tax-efficient due to the dividend tax credit and the corporate rate of only 11%.

When to Stay a Sole Proprietor

A sole proprietorship is simpler, cheaper to run, and may actually be more tax-efficient at lower income levels.

Revenue under $60,000 — incorporation overhead often outweighs savings
Business losses can offset your personal income directly
No annual corporate filings, minute books, or T2 returns
Capital cost (setup $0, annual accounting $0–$1,500)
Self-employed CPP builds retirement benefits at a lower net cost

Revenue Thresholds — Rule of Thumb

Under $30K

Sole prop recommended. No GST, no corp overhead. Keep it simple.

$30K–$60K

GST registration required either way. Run the numbers — often sole prop still wins after corp costs.

$60K–$100K

Incorporation starts paying off. Dividend strategy can save $5K–$15K/year.

$100K+

Incorporate. Tax deferral alone saves thousands annually. Dividend mixing optimizes brackets.

The $3,500 Salary Strategy

The CPP basic exemption is $3,500. Paying yourself exactly $3,500 in salary creates a T4 record (useful for mortgage applications, credit, and maintaining your CPP contribution history) without triggering any CPP premiums — the $3,500 falls entirely within the exemption.

If your salary exceeds $3,500, CPP applies to the excess at 5.95% (employee) + 5.95% (employer), up to a maximum pensionable earnings of $71,300 in 2025.

When to Incorporate

Corporations create a tax deferral opportunity — the 11% corporate rate vs. your personal marginal rate of 25–48% means money left in the corporation is taxed much less until you take it out.

Revenue consistently above $60,000–$80,000/year
You don't need all the profit to live on — can leave income in corp
Protecting personal assets from business liability
Planning for future sale of the business (Lifetime Capital Gains Exemption)
Multiple shareholders or income splitting possibilities

Salary vs Dividend — The Core Trade-off

Salary (above $3,500): Deductible to the corporation, reduces corporate tax. Creates RRSP room (18% of earned income). Triggers CPP contributions — employee and employer portions combined cost up to $8,068/year.

Dividends: Paid from after-tax corporate income. No CPP, no RRSP room. Non-eligible dividends (typical for CCPC small-business income) carry a 15% gross-up and 9.03% federal dividend tax credit. Each province also provides its own non-eligible DTC — ranging from 0.67% (YT) to 6.0% (NT) of the taxable dividend — which this calculator applies automatically based on your selected province.
