Frequently Asked Questions
What is the corporate tax rate for small businesses in Alberta?
Canadian-Controlled Private Corporations (CCPCs) in Alberta benefit from a combined federal-provincial tax rate of 11% on the first $500,000 of active business income annually. This consists of the 9% federal small business rate plus Alberta's 2% provincial rate. Income above $500,000 is taxed at the general corporate rate of approximately 23% (15% federal + 8% Alberta). This significant tax advantage makes incorporation attractive for profitable Calgary businesses.
Does my Calgary business need to register for GST/HST?
If your business earns more than $30,000 in revenue over four consecutive calendar quarters, registration is mandatory. Even below that threshold, voluntary registration can be beneficial because it lets you claim input tax credits on business purchases. We help you determine the right approach and handle all registration and filing.
Do you offer representation for CRA audits?
Yes, our CPA-led team provides professional representation and expert advice during CRA audits. We manage the communication and ensure your interests are protected with detailed documentation and strategic reporting.
Can you provide a business valuation for a Canadian company?
Absolutely. We offer professional business valuations and strategic planning that are essential for owners looking to sell, merge, or prepare for future succession and investment opportunities.
What business expenses can I deduct?
Common deductible expenses include rent, utilities, insurance, office supplies, professional fees, advertising, vehicle expenses (business-use portion), travel, meals (50% deductible for business purposes), employee wages, subcontractor payments, software subscriptions, and equipment (through CCA). We review your entire spending to ensure you're claiming everything you're entitled to.
How do I set up a new business for tax purposes in Calgary?
The steps include incorporating (federally or provincially in Alberta), obtaining a Business Number from CRA, registering for GST/HST if applicable, setting up a payroll account if you'll have employees, registering with WCB, and filing your Alberta Corporate Registry annual return. We handle all of this during onboarding so you start on the right foot.
What is the cost of bookkeeping for a small business in Calgary?
Bookkeeping costs in Calgary vary depending on the volume of transactions, the complexity of your business, and the frequency of service. For a typical small business with 50–150 transactions per month, you can expect to pay $250–$500 per month for professional bookkeeping. Businesses with higher transaction volumes, multiple bank accounts, or inventory tracking may pay $500–$1,000 per month. This is significantly less than hiring a full-time bookkeeper (typically $40,000–$55,000 per year plus benefits), and you get CPA-supervised accuracy.
