What you need to know about sole proprietor + HST filing

Sole proprietors receive more than you think

Running a business as a sole proprietor means every dollar earned and every expense tracked directly affects your personal taxes. Whether operating in the Greater Toronto Area (GTA) or a non-resident while earning Canadian business income, accurate accounting and HST filing are essential to staying compliant and maximizing profitability.

Specialized support for non-residents

Non-residents who operate businesses or earn self-employment income from Canadian sources face additional reporting rules. Determining HST registration obligations, withholding tax requirements, and treaty eligibility depends on the type of business activity and where services are performed.

Why Our Clients Love Us

Frequently asked questions

  • A sole proprietor is an individual who owns and operates a business under their own name, without incorporating. All business income and expenses are reported on a personal tax return using the T2125 – Statement of Business or Professional Activities form. It’s the simplest and most common business structure for freelancers, consultants, and small business owners in Canada.

  • If your business earns more than $30,000 in sales within a 12-month period, you must register for an HST number with the Canada Revenue Agency (CRA). Once registered, you’re required to charge HST on taxable goods and services, file HST returns (usually quarterly or annually), and remit the collected tax to the CRA.

  • When filing HST, you report the HST collected from clients and subtract the input tax credits (ITCs) paid on business expenses. The difference is the amount you owe to the CRA or can claim as a refund. HST returns can be filed online through the CRA’s portal and are due either quarterly or annually, depending on your revenue and filing schedule.

  • Sole proprietors can claim a wide range of business-related expenses, including:

    • Home office space and utilities

    • Vehicle and mileage costs

    • Internet and phone bills

    • Equipment, supplies, and tools

    • Advertising and marketing expenses

    • Accounting, software, and professional fees

    Keeping organized records and receipts is key to maximizing deductions and lowering taxable income.

  • Non-residents earning income from a Canadian business or Canadian clients must file a Canadian tax return to report that income. The CRA determines tax obligations based on the source of income and residency status.
    Depending on the business type and treaty agreements between Canada and your country of residence, you may also need to register for HST and file regular returns if providing taxable services in Canada.

  • Yes. A non-resident can register for HST if selling taxable goods or services to Canadian customers. In some cases, registration is mandatory once the $30,000 threshold in Canadian sales is reached. HST filing rules for non-residents can be complex, so ensuring the correct tax treatment and registration setup is crucial for compliance.

  • A sole proprietor reports business income on their personal tax return, while a corporation files a separate corporate tax return (T2). Sole proprietorships are simpler to manage and have lower administrative costs, but corporations offer liability protection and potential tax advantages. The best structure depends on income level, growth plans, and business goals.

  • Yes. If business expenses exceed income, the loss can often be applied to reduce other taxable income on your personal tax return. This can result in a lower overall tax bill or a refund from the CRA. Losses may also be carried forward to future tax years.

  • Failing to file an HST return on time may result in CRA penalties and interest charges. If you collected HST but did not remit it, the CRA can charge additional fines. Filing all returns promptly, even if no tax is owed, keeps your business in good standing.

  • Most freelancers automatically qualify as sole proprietors by default if earning self-employment income. You don’t need to register a separate business unless you choose to operate under a business name or exceed the HST threshold. Freelancers must still track income and expenses and file taxes using the T2125 form each year.

  • The CRA requires all business owners to keep detailed financial records for at least six years. This includes invoices, receipts, bank statements, mileage logs, and HST filings. Proper recordkeeping helps verify claims and protects against penalties during a CRA review or audit.

  • No. Some provinces like Ontario use HST (Harmonized Sales Tax), which combines federal and provincial tax rates. Others, like Alberta, only have GST (Goods and Services Tax). The rate charged depends on where your customers are located, not where your business operates.

  • Self-employment income is reported on the T2125 form, which is filed with your personal income tax return. This form summarizes business income, expenses, and net profit (or loss) for the year. The CRA uses this information to calculate how much tax you owe or the refund you’re eligible for.
