Should you incorporate your Alberta business?

Corporate tax and owner cash flow

Key takeaways

  • The strongest tax deferral often comes from profits you can leave in the company.
  • Compare personal withdrawals and annual costs before choosing the structure.
  • Use a forecast of retained profit, cash needs and ownership plans.

A growing business brings new decisions. You may be hiring your first employee, signing larger contracts or finding that the business earns more than you need to take home. At that point, incorporation often becomes part of the conversation.

For an Edmonton business owner, the right decision depends on profit, personal cash needs, business risk and future plans. A useful incorporation review compares the money you would keep under each structure after taxes and the costs of running the business.

The corporate tax and financial benefits

Corporate tax deferral. For an ordinary eligible Alberta small business, the combined rate on income qualifying for both small business deductions is currently 11%: 9% federal plus 2% Alberta. Eligibility, available business limits and the type of income matter. Investment income and personal services business income need different treatment. CRA corporate rates; Alberta corporate tax rates.

Personal tax planning. Keeping earnings in the corporation can postpone the personal tax associated with taking that money out. Plan withdrawals around your household needs and other income. Dividends remain taxable personally, so a low corporate rate alone does not establish the total tax cost. CRA taxable dividend guidance.

Cash available for growth. A useful deferral can leave more money inside the business for inventory, equipment or a reserve against slow months. Compare that benefit with the added annual costs and the tax on future withdrawals. This is a cash-flow planning benefit; incorporation does not guarantee financing or permanent tax savings.

A simple comparison of retained profit

Assume an additional $100,000 of business profit can be left invested in the business. All of it qualifies for the combined 11% small business rate. For comparison only, assume the same profit would face an effective 40% personal income tax rate as sole-proprietor income. The 40% is illustrative, not an Alberta tax-bracket quotation. Ignore CPP, credits, setup costs and annual corporate costs.

Current tax and cash on an additional $100,000 of profit
On the additional $100,000Eligible corporationSole proprietor at assumed 40%
Current income tax$11,000$40,000
Cash remaining after that tax$89,000 in the corporation$60,000 personally

Our calculation leaves $29,000 more in the corporation for now. It is a deferral comparison before personal withdrawals, not a claim of $29,000 in permanent savings. The corporate cash still belongs to the company; personal tax may arise when it is paid to you.

Start with the profit you can leave in the business

Revenue tells you how much you sell. Profit tells you what remains after expenses. Your personal budget then helps determine how much of that profit you need to withdraw.

As a sole proprietor, you generally report your net business income on your personal tax return. Leaving some of the cash in a separate business bank account does not, by itself, postpone the tax on that income. CRA guidance on self-employment income.

Consider two hypothetical owners with similarly profitable businesses. One needs almost all the available earnings to cover household spending and taxes. The other can consistently leave a substantial amount in the company. Their incorporation decisions may be quite different, even when their sales and profits look alike.

Include the tax on money paid to you

The corporate tax rate is only one part of the calculation. Your personal tax position also matters when the company pays you.

Taxable dividends are included in a shareholder's income. The dividend gross-up and tax credit system is intended to recognize corporate tax already paid, although the combined result varies with the circumstances. A low corporate rate therefore cannot be treated as the final tax rate on money you will spend personally. CRA guidance on taxable dividends.

Ask for a comparison that shows corporate tax, personal tax, payroll costs where applicable, and the cash left for both you and the business. Include your other income and expected withdrawals. If your personal spending will rise next year, the forecast should reflect that.

Budget for the ongoing work

A corporation is a separate legal entity. Organize its banking and accounting records separately, and obtain a checklist of ongoing corporate registry and legal requirements. CRA corporation guidance.

A corporation generally files a T2 income tax return each year, even when no tax is owing. GST and payroll filings may also apply. CRA corporation guidance.

An Alberta corporate income tax return (AT1) may also be required. Filing the federal T2 does not automatically satisfy the provincial filing requirement; Alberta has its own exemptions. Alberta AT1 filing requirements.

Before deciding, ask what the annual work will involve and what it will cost. Include bookkeeping, financial statements, corporate tax returns, owner compensation records and legal maintenance. Someone also needs to reconcile the bank accounts, organize purchase records and keep track of filing and payment dates.

A structure that looks attractive on a tax calculation still needs to work with your time, systems and budget.

Review the working relationship if you provide services

Consultants and contractors should examine how they work with their customers before incorporating.

If you would be an employee of a customer without the corporation, and the other statutory conditions are met, your company may be a personal services business. That status can remove access to the small business deduction, restrict deductible expenses and result in additional corporate tax. CRA personal services business fact sheet.

Having one major customer is a reason to look closely at the arrangement; it does not decide the issue by itself. Bring your service agreement and explain how the work operates in practice. The review should happen before a forecast assumes that ordinary small business tax treatment will apply.

Consider ownership, risk and future plans

Incorporation also changes the legal structure. A corporation can own property and enter contracts in its own name. Shareholders generally have limited liability, but personal guarantees and certain director liabilities can still expose an owner personally. CRA guidance on corporate liability.

Discuss those risks with your lawyer alongside insurance and contract terms. If another person will become an owner, clarify decision-making, funding obligations and what happens if someone wants to leave. A future sale or transfer to family is also a reason to plan the ownership structure early.

Tell your accountant about every corporation you or related owners control. Associated corporations generally share the federal small business limit, which can change the expected tax result. CRA guidance on the small business deduction.

If you already operate a business, plan the transition as well: equipment, inventory, customer contracts, banking and tax accounts all need attention.

Bring these details to an incorporation discussion

A useful starting package includes:

  • Your latest tax return and current business income and expense reports.
  • An estimate of the money you need personally each month, including taxes.
  • Expected profits, hiring and major purchases over the next two years.
  • A list of business assets, debts, leases and significant customer contracts.
  • Details of proposed owners and any other corporations they control.

With those facts, you can compare incorporating now with continuing under your present structure and revisiting the decision at an agreed point.

Common questions

Will incorporation always lower my total tax

No. Compare corporate and personal tax together, including the cost of maintaining the company. The practical advantage is often strongest when meaningful profits can remain in the business. Money needed immediately for personal spending requires a different calculation.

Is there a single profit level at which I should incorporate

No single number decides it. Retained profit, withdrawals, business risk, ownership plans and ongoing costs determine whether the structure is useful.
