Your side hustle is growing. Are your finances keeping up?

By Lil Rourke, CPA | Rourke, CPA – Professional Corporation

Perhaps you started selling something you make, taking on freelance projects or offering a service outside your regular working hours. At first, it was a little extra income. Now you have repeat customers, more enquiries and a growing list of things to do.

You might even be wondering whether you could make this your full-time business.

You’re certainly not alone. Ownr, RBC’s business registration and incorporation platform, recently released its 2026 Canadian Side Hustle Report, based on an Ipsos survey. It found that 23% of Canadians surveyed earn income through a side hustle, and 19% of current side hustlers say they are likely to leave their job to pursue their venture full time.

But the findings also highlight a gap: 37% of side hustlers don’t know when they need to register their business, and 38% don’t understand the legal requirements that apply to them.

That uncertainty is understandable. Most people start with an idea, a skill or an opportunity. The accounting and paperwork often come later.

However, some responsibilities arise well before you leave your regular job.

Start with the right advice

Before launching your business, speak with an accountant and a lawyer to help lay a solid foundation.

An accountant can help you choose an appropriate business structure, understand your tax obligations, set up your bookkeeping and plan for cash flow. A lawyer can advise on the legal structure, contracts, ownership arrangements and potential liabilities.

Getting advice early can help you avoid costly mistakes and put the right arrangements in place from the beginning.

Already started? It’s still a good time to review your setup—especially if the business is growing or you’re considering taking it full time.

Here are the questions I would encourage you to consider.

1. Do I need to report the income if it’s just something I do on the side?

Calling something a “side hustle” doesn’t give it a special tax exemption.

If you are earning business income, you need to report it—even if you haven’t registered a business name, incorporated or received a tax slip. Payments made in cash or by e-transfer still count.

For a sole proprietor, business income and eligible expenses are generally reported on Form T2125 as part of the personal income tax return.

You do not need to earn $30,000 before reporting business income.

The amount of income tax you ultimately owe depends on your overall circumstances. But reporting the income and determining whether tax is payable are two different questions.

If you are unsure whether an activity is a business or a personal hobby, ask before assuming the income is exempt—or that its costs can be deducted.

2. What does “registering my business” actually mean?

This is where several different requirements can get mixed together.

Registering a business name: In most provinces and territories, a sole proprietor generally needs to register a business name if operating under a name other than their own legal name. That requirement is separate from the amount of revenue earned. Check the rules where you plan to operate, as requirements and exceptions vary by jurisdiction.

Registering for GST/HST: This is a separate CRA requirement, generally based on taxable sales and the small supplier rules.

Incorporating: This creates a separate legal entity. Registering a business name does not incorporate your business.

Hiring employees: This brings payroll responsibilities, including applicable deductions and employer contributions. Simply calling someone a contractor does not determine their employment status.

Depending on your activity and location, you should also check whether licences, permits or other approvals apply.

These are separate decisions. A single revenue threshold does not answer all of them.

3. When do I need to register for GST/HST?

For most businesses making taxable sales, mandatory registration generally arises when taxable revenue exceeds $30,000 in a single calendar quarter or over four consecutive calendar quarters.

The test uses revenue before expenses, rather than profit. It generally includes worldwide taxable sales from all your businesses, as well as applicable associated persons. Your employment salary is not a business sale.

If you exceed $30,000 in one quarter, GST/HST generally applies to the sale that takes you over the threshold. If you exceed it over consecutive quarters without exceeding it in a single quarter, the start date follows different rules.

Some activities, including commercial ride-sharing, have special requirements.

There may also be good reasons to register voluntarily for GST/HST before reaching $30,000 in taxable revenue. For example:

• Recovering GST/HST on eligible business purchases. Registration may allow you to claim input tax credits on expenses such as equipment, supplies and software used in your commercial activities. This can be particularly helpful when you have significant startup costs.

• Preparing for growth. If you expect to exceed the threshold soon, registering early lets you build GST/HST into your pricing, invoicing and bookkeeping from the beginning.

• Supporting customer confidence. Some potential customers may associate GST/HST registration with an established business. If you do not charge GST/HST, they may assume your sales are below $30,000 and view your business as smaller or less established. That perception may be inaccurate, but registration can help support the professional image you want to present.

  
  

Voluntary registration also brings responsibilities to charge GST/HST on applicable sales, file returns and remit amounts owing. Your accountant can help you decide whether registering early makes sense.

The practical message is simple: monitor your sales throughout the year. Waiting until your accountant prepares your tax return may mean discovering that you should already have been collecting GST/HST.

4. Am I setting aside enough for tax?

The money coming into your bank account is not necessarily all available to spend.

If you have employment income as well as a sole proprietorship, your business profit forms part of your personal income. The tax withheld from your paycheque may not cover the additional income from your business.

CPP can also affect the amount owing. Self-employed individuals generally pay both the employee and employer portions on applicable earnings. If you also contribute through employment, those contributions and the annual limits need to be considered.

Rather than choosing a tax savings percentage at random, have your accountant estimate what you should set aside based on your salary, expected business profit and personal circumstances.

If you collect GST/HST, plan for that obligation separately. It should not become part of the cash you rely on for everyday spending.

5. Do I know what the business is actually earning?

Sales are exciting. Profit tells you more about whether the business is working.

Consider someone who earns $2,500 a month from a side business. After materials, software, advertising, payment processing and other operating costs of $1,000, they have $1,500 left before income tax and any applicable CPP.

If they spend 50 hours a month on the business, that works out to $30 an hour before those obligations.

That might be a worthwhile result. It might also show that pricing or costs need attention before the business can replace a salary.

This example is illustrative only.

Remember to count the time spent answering enquiries, preparing quotes, ordering supplies, keeping records and following up on payments. Those hours are part of running the business, even when you cannot bill for them directly.

6. Are my records keeping up with the business?

A growing business needs a reliable way to track income, expenses and amounts customers still owe.

My recommendation is to establish a routine early:

• Keep business transactions separate from personal spending.

• Record all sales, including cash and e-transfer payments.

• Save invoices and receipts as you go.

• Review the numbers each month.

• Track GST/HST obligations before the threshold becomes an issue.

  
  

Eligible business expenses can reduce taxable profit, but a purchase does not automatically become deductible because you use it occasionally for work. Personal spending must be excluded, mixed-use costs need an appropriate allocation, and some purchases are deducted over time rather than all at once. Supporting documentation matters.

A simple system you use consistently is far more useful than a complicated one you avoid.

7. Should I incorporate?

Incorporation deserves a conversation with your accountant and lawyer. It should not be an automatic response to reaching a particular sales figure.

I would want to understand your expected profit, how much money you need to withdraw for personal living costs, the risks involved in the business and your plans for growth.

There are also ongoing costs and responsibilities. A corporation is a separate legal entity and generally needs its own corporate income tax return each year, even when no tax is payable.

If you need to take out most of the earnings to pay household bills, the potential tax benefit may be quite different from a business that can retain money for future growth.

The right structure should support your circumstances and goals.

8. What would need to be true before I leave my job?

Before making the leap, look beyond your best sales month.

Ask yourself:

• Has the business generated consistent profit over several months?

• How much cash do I need each month for household expenses?

• What will replace the benefits, pension contributions and paid time off provided by my employer?

• Do I have enough cash to manage a slow period or a late-paying customer?

• Am I relying heavily on one customer?

• Will more available working hours realistically lead to more profitable sales?

• Have I included the costs of bookkeeping, insurance, professional advice and administration?

  
  

A cash flow forecast can help you see when money is likely to arrive, when bills must be paid and how much you can reasonably draw from the business.

It can also help you set a meaningful milestone: a level of consistent profit and available cash that supports the transition.

You can build the foundations while the business is still small

Your side hustle may eventually become your full-time work. It may also remain a rewarding source of additional income. Both can be successful outcomes.

Either way, getting professional advice early, understanding your tax obligations, keeping reliable records and knowing what you actually earn will help you make better decisions.

You don’t have to have everything figured out on day one. But you do need a clear picture of where the business stands and what its next stage will require.
