Who We Help

Sole Proprietorship Tax Services We Provide

Self-Employment Income Reporting

Sole proprietors report business income on their personal T1 tax return using Form T2125 (Statement of Business or Professional Activities). We prepare this form accurately, reporting all revenue sources and claiming every eligible deduction. We also ensure proper reporting of income from multiple clients, including reconciliation with T4A slips received from payers.

Business Expense Deduction Optimization

Self-employed individuals can deduct a wide range of business expenses—supplies, advertising, professional fees, insurance, bank charges, meals (50%), and more. We systematically review your expenses to ensure you're claiming everything you're entitled to, while keeping claims defensible in case of CRA review.

Home Office Expense Claims

If you work from home, you can claim a portion of rent or mortgage interest, property taxes, utilities, insurance, and maintenance based on the percentage of your home used for business. We calculate the optimal method (detailed vs. flat rate) and ensure your claims are properly supported and documented.

Vehicle Expense Deductions

If you use your vehicle for business, you can deduct fuel, maintenance, insurance, financing costs, and depreciation based on business-use percentage. We help you set up a mileage log, calculate the deduction, and choose between the detailed method and the simplified per-kilometre rate.

Incorporation Assessment

When your sole proprietorship income grows, incorporation may offer significant tax savings. The 11% small business rate in Alberta vs. personal rates up to 48% means incorporation can defer substantial tax. We analyze your income, expenses, and goals to recommend the right time to incorporate and handle the transition.

Our Process

Step 1: Initial Review and Setup

We review your current business situation, income sources, expense categories, and record-keeping practices. We set up a simple bookkeeping system (if you don't have one) and create a plan to maximize your deductions.

Step 2: Quarterly Planning and Installments

CRA requires tax installments if you owe more than $3,000 in a year. We calculate your installment amounts, set up payment reminders, and adjust estimates as your income changes throughout the year.

Step 3: Tax Return Preparation and Filing

We prepare your T1 return with T2125, claim all eligible deductions, calculate CPP self-employment contributions, and file before the June 15 deadline (self-employed individuals get an extended filing deadline, though taxes owing are still due April 30).

Local Expertise: Sole Proprietorships in Calgary and Alberta

Calgary has a thriving self-employment community across trades, professional services, technology, and the gig economy. Alberta's flat 10% provincial rate and no PST simplify tax planning for sole proprietors. However, self-employed Calgarians pay both the employee and employer portions of CPP (11.9% total on pensionable earnings), which is a significant cost that proper planning can help manage through RRSP contributions and other strategies.

We understand the seasonal income patterns common in Calgary's economy—many sole proprietors in construction, landscaping, and energy services earn most of their income in specific months. We plan installments and deductions to smooth your tax burden across the year.

What You Can Expect

Timelines: T1 returns with T2125 prepared well before the June 15 filing deadline. Quarterly installment calculations provided before each due date. Incorporation assessments completed within one week.

Pricing: Sole proprietor tax returns start at competitive rates based on complexity. Call 403-768-4444 or book a free consultation.

Why Sole Proprietors Choose Tax Buddies

Frequently Asked Questions — Sole Proprietorship Tax in Calgary

What expenses can I deduct as a sole proprietor in Calgary? Common deductions include home office expenses, vehicle costs, supplies, professional fees, insurance, advertising, phone and internet, bank charges, and meals with clients (50%). Tax Buddies systematically reviews your expenses to maximize deductions while staying CRA-compliant.

Should I incorporate or stay a sole proprietor? Incorporation typically makes sense when business income consistently exceeds $50,000–$75,000, you want liability protection, or you don't need all the business income personally. The 11% corporate rate vs. up to 48% personal rate creates significant deferral opportunity. We analyze your specific situation.

When is the tax filing deadline for sole proprietors? Self-employed individuals have until June 15 to file their T1 returns. However, any taxes owing are still due by April 30. We recommend filing early to avoid surprises and interest charges.

How do CPP contributions work for self-employed individuals? Self-employed Calgarians pay both the employee and employer portions of CPP—approximately 11.9% total on net self-employment earnings between $3,500 and the annual maximum. This is a significant cost but contributes to your retirement benefits.

Do I need to charge GST as a sole proprietor? You must register for GST when your revenue exceeds $30,000 in four consecutive quarters. Below that threshold, registration is optional but can be beneficial if you have significant business purchases (you can claim input tax credits). We advise on the best approach.

How do I calculate home office deductions? Determine the percentage of your home used exclusively for business (by area or rooms). Apply that percentage to eligible expenses: rent or mortgage interest, property taxes, utilities, insurance, and maintenance. The flat rate method ($2/day, up to $500/year) is simpler but usually yields a smaller deduction.

What is the T2125 form? The T2125 Statement of Business or Professional Activities is attached to your T1 personal return and reports your self-employment revenue, expenses, and net income. Tax Buddies prepares this form as part of your tax return.

How do quarterly tax installments work? If you'll owe more than $3,000 in a year, CRA requires quarterly installment payments (March 15, June 15, September 15, December 15). We calculate the amounts using the method that results in the lowest payments and ensure you stay on schedule.

Can I deduct my vehicle expenses as a sole proprietor? Yes, based on the business-use percentage. Keep a mileage log documenting business trips. Deductible expenses include fuel, insurance, maintenance, financing, and CCA. We calculate the optimal deduction method for your situation.

What records should I keep as a sole proprietor? All receipts, invoices, bank statements, mileage logs, and contracts for at least six years. We help set up a simple cloud-based system for organizing records so you're prepared if CRA audits.
