Side Hustle and Gig Work Deductions: What Actually Qualifies, and On Which Form

Most guides to side hustle deductions get two things wrong, and both are the kind of wrong that produces a reassessment rather than a rounding error.

The first is the form. Self-employment income and expenses go on Form T2125, Statement of Business or Professional Activities, filed with your T1. Schedule 8 is a different form entirely: it calculates CPP contributions on self-employment income. Advice telling you to report side income on Schedule 8 is describing a form that does not do that.

The second is that a great deal of what circulates online is American. Flat per-square-foot home office rates, a $500 threshold that turns an expense into a capital asset, and a per-kilometre rate a self-employed person can elect to use instead of tracking costs are all rules that do not exist in Canadian tax law. They appear in Canadian articles constantly.

Here is what the rules actually are.

First: is it a business at all?

There has to be a source of income pursued in a commercial manner. The Supreme Court settled this in 2002, and it is a lower bar than the “reasonable expectation of profit” test that older commentary still repeats: where there is no personal element to the activity, the pursuit-of-profit test is generally satisfied and the CRA does not second-guess business judgment.

Where an activity has a personal or hobby element, the question becomes whether it is carried on in a sufficiently commercial manner. Losses on an activity you would do anyway, that has never come close to profitability, are where this becomes contentious.

Practically, what makes an activity look commercial: separate banking, invoices and records, a pricing structure that could produce a profit, marketing effort, and time spent. What makes it look personal: consumption benefits to you and your family, no attempt to price for profit, and years of losses with no change in approach.

Home office: proportional, and there is no flat rate

Business-use-of-home expenses are available to a self-employed person if the space is either:

• your principal place of business, or
• used exclusively to earn business income and used on a regular and continuous basis for meeting clients, customers or patients

The first branch is the one most side hustlers rely on, and it does not require a dedicated room. The requirements are at business-use-of-home expenses.

There is no simplified or flat-rate method for the self-employed. The temporary flat rate that existed during the pandemic applied to employees and has not been available since the 2022 tax year. The only method is proportional: a reasonable basis, usually area, and where a space is shared with personal use, further reduced by the proportion of time it is used for business.

Two cautions. The claim cannot create or increase a business loss: it is limited to net income before the home expense, with the excess carried forward to a future year of the same business. And do not claim CCA on your home. Doing so can put the business portion of the property outside the principal residence exemption, which trades a small annual deduction for tax on part of the gain when you sell. The proportional calculation is worked through in the home office deduction for the self-employed.

Vehicle: actual costs, tracked, in kilometres

A self-employed person cannot claim a per-kilometre rate instead of actual expenses. The rates published by the CRA are for employers paying allowances to employees and for employee claims. They are not an election available on T2125. Any guide telling a rideshare driver to multiply business kilometres by a published rate is describing a rule that does not apply to them.

What you claim instead: the business proportion of the actual costs of operating the vehicle. Fuel, insurance, licence and registration, maintenance and repairs, lease payments or capital cost allowance, and interest on a vehicle loan. Lease and interest deductions are subject to annual ceilings, and passenger vehicles above a prescribed cost fall into a restricted CCA class of their own. Those limits are announced annually, so take them from the CRA rather than an article.

The proportion is business kilometres over total kilometres for the year, supported by a logbook. Record the odometer at the start and end of the year, and for each business trip the date, destination, purpose and distance.

Travel between home and a regular place of business is personal, not business. For a courier or rideshare driver whose home is the base of the business, the analysis is different, but the distinction still matters: time logged into a platform waiting for a job, versus driving to a location before logging in, is not the same thing.

Equipment: there is no $500 rule

Whether an outlay is currently deductible or capitalised depends on whether it is a current expense or a capital one, not on a dollar threshold. There is no $500 line in the Income Tax Act. A durable asset with lasting benefit is capitalised and deducted over time through capital cost allowance, whatever it cost.

The class determines the rate, and the rates commonly repeated online are wrong:

Confirm any class before claiming at classes of depreciable property. CCA is optional in any year and the half-year rule generally applies in the year of acquisition, though accelerated first-year rules have applied to property acquired in certain windows.

Mixed-use assets are claimed proportionally. A laptop used 60% for the side business goes into the class at 60% of its cost. Claiming a personal phone or laptop at 100% is one of the most reliable ways to attract questions about everything else on the form.

Meals, and the rule people over-apply

Business meals and entertainment are limited to 50% of the lesser of the amount incurred and a reasonable amount. That is the general rule, and it applies to a meal with a client where business was actually discussed, and to meals while travelling on business.

It does not turn an ordinary personal lunch into a half-deductible one. A meal eaten alone between jobs is personal, whether or not you were working. Long-haul transport employees and a few other categories have their own rules.

The documentation that survives a review is the receipt plus, written at the time, who was present and what the business purpose was. A credit card statement line is proof that money moved, not proof of what it bought.

What genuinely gets missed

The categories most side hustlers leave unclaimed are unglamorous and add up:

• Platform and processing fees. The commission a platform takes, payment processor fees, and currency conversion charges are all business expenses. Report gross revenue and deduct them, rather than reporting net
• Business use of phone and internet, at a supportable proportion
• Advertising, including online ads, and website hosting and domain costs
• Accounting and legal fees relating to the business
• Professional development directly related to the current business. Training to enter a new field is generally a capital or personal outlay, not a current expense
• Business insurance, and licences and permits
• Bank charges on the business account, which is one more reason to have one
• Bad debts actually written off, where the income was previously included

GST/HST: the exception that catches drivers

The small supplier threshold is $30,000 of worldwide taxable revenue over four consecutive calendar quarters. Below it, registration is optional.

Taxi and commercial ride-sharing drivers are outside that rule entirely. If you supply taxable passenger transportation services, you must register for GST/HST regardless of revenue, from your first fare. The CRA states this at GST/HST for taxi operators and commercial ride-sharing drivers. Food delivery on its own is not passenger transportation, so the ordinary threshold applies to a courier who does not also carry passengers.

Registering voluntarily is often worth it for a side business with real equipment purchases, because input tax credits on those purchases are only recoverable once registered. See GST/HST registration for small business.

The platform now tells the CRA what you earned

Under the reporting rules for digital platform operators, in force since 1 January 2024, platforms collect and verify seller information and report it to the CRA annually, giving you a copy by 31 January. Your reported income is compared to theirs.

Report gross platform revenue and deduct the platform’s fees as an expense. Reporting the net figure you received produces a mismatch against the gross number the platform filed, and that mismatch is what generates the letter. The CRA’s overview for gig workers is at the gig economy.

What a defensible file looks like

Records must be kept for six years from the end of the last tax year they relate to, and electronic records must remain in an electronically readable format for that period, per keeping records.

The four things that decide a review:

1. A separate bank account. Commingled accounts turn a narrow question into a line-by-line examination of your personal spending
2. A contemporaneous vehicle log. Reconstructed logs are recognised as reconstructed and are worth far less
3. Source documents, not summaries. The invoice is the evidence
4. A written note of business purpose on anything unusual, made at the time

None of this is about being aggressive or conservative. A well-documented claim survives. An undocumented one does not, however modest it was. Related reading: freelancer financial planning for the cash flow and instalment side.

Once a side business has a T2125 attached to it, the return stops being a fifteen-minute job. It is the point where a lot of people stop self-filing and have the return prepared instead.

If you have a side business and are not sure whether your home office qualifies, how to split a vehicle, or whether you should have registered for GST/HST last year, that is worth checking before you file. Fixing a return is straightforward. Defending an undocumented claim after the fact is not.
