Can You Deduct Start-Up Costs Before Your First Client in Canada?

Can You Claim Expenses Before Earning Revenue?

You bought a domain, software, insurance, and equipment before your first client paid you. Can those start-up costs go on your T2125?

Possibly. The CRA focuses on whether you were already carrying on a business when the cost was incurred—not whether you had made your first sale or formally registered a business name. The important date is when your business actually started.

When Does a Business Start for Tax Purposes?

There is no universal start date. The CRA says you must have carried on a business in the fiscal period in which you incurred a deductible business expense. It distinguishes between merely considering a business and taking meaningful preliminary steps toward normal operations.

For a freelancer, evidence that the business has started may include:

Simply researching several unrelated business ideas or buying something you might use someday is weaker. Your start date should reflect serious, reasonably continuous activity connected to a specific income-earning business.

Registration Date and First Sale Are Not the Test

A sole proprietor can operate under their own legal name without registering a separate business name in many situations, subject to provincial rules. That means registration does not automatically create the business for income-tax purposes.

Your first payment is not necessarily the start date either. A freelance designer may begin operating when they launch a portfolio and actively pitch prospects in February, then land the first paid project in April. Reasonable February and March operating expenses may still relate to an active business.

Document the date you believe operations began and what you were doing: save website launch records, proposals, licence applications, contracts, and dated marketing activity.

Current Expense or Capital Property?

Even after establishing the start date, each cost needs the correct tax treatment.

Current expenses are recurring or short-term costs that may generally be deducted in the year incurred if they are reasonable and business-related. Examples include:

Capital property provides an enduring benefit. A laptop, camera, furniture, or other long-lasting equipment will often be claimed over time through capital cost allowance (CCA) rather than deducted in full immediately. Property bought before operations began may still have a capital cost when it is later used in the business, but the CCA and available-for-use rules matter.

What Usually Cannot Be Deducted?

Costs incurred while a business was only a vague possibility generally do not become current T2125 deductions just because you later started operating. You also cannot claim:

When the start date or a large purchase is uncertain, ask a tax professional to review the facts.

Build a Defensible Start-Up Expense File

For every early expense, keep the receipt, date, business purpose, payment proof, and category. Add a short note explaining how it supported the business and whether it is current or capital.
