Corporate Tax

Corporate Tax Rates in Alberta (2025)

Alberta’s combined federal and provincial corporate tax rate for small businesses is 11% on the first $500,000 of active business income — one of the lowest combined rates in Canada. This rate is made up of the federal small business rate of 9% and Alberta’s provincial small business rate of 2%. On income above $500,000, the combined rate rises to 23% (15% federal plus 8% provincial). Working with a CPA who understands both the federal and Alberta provincial tax systems ensures your corporation takes full advantage of these rates.

What Is Included in Our Corporate Tax Service

Our corporate tax service is designed to be comprehensive — not a simple return preparation and filing. When you work with Nguyen Scott LLP on your corporate taxes, we prepare and file your T2 Corporation Income Tax Return, prepare your Alberta AT1 return for filing with Alberta Tax and Revenue Administration, calculate and advise on your instalment payment schedule, prepare T4 slips and summary for payroll and T5 slips for dividends, assist with GST and WCB returns, and provide year-round tax planning advice tailored to your business and personal situation.

Owner-Manager Tax Planning

For incorporated business owners, corporate tax does not exist in isolation from your personal tax. The compensation decisions you make — salary versus dividends, timing of distributions, dividend amounts — directly affect both what your corporation pays in tax and what you pay personally. We work with owner-managers to find the most tax-efficient structure for their specific income level, RRSP goals, and business objectives. This is one of the most concrete ways a CPA adds measurable value year after year.

Industries We Serve

Nguyen Scott LLP works with corporations across a wide range of Alberta industries, including construction and trades, oil and gas services, real estate investment, medical and healthcare practices, transportation and logistics, retail businesses, agriculture and farming, and not-for-profit organizations. Understanding the specific tax treatment, deduction categories, and planning considerations relevant to your industry means you receive advice that applies to your actual situation.

Corporate Tax Deadlines

Your T2 Corporation Income Tax Return must be filed within six months of your fiscal year-end. However, your tax payment is due earlier — typically within two or three months of year-end depending on your corporation’s situation. Missing the payment deadline triggers interest charges even if your return is filed on time. We track these deadlines for our clients and provide advance notice when payment and filing dates are approaching.

New Corporations and Wind-Up

We handle corporate tax for newly incorporated businesses navigating their first filing, as well as for corporations undergoing significant changes — amalgamations, wind-ups, and changes in fiscal year. Getting the first few years of a corporation’s tax filing right establishes a clean foundation for the years that follow.
