Timing is a lever. When you buy equipment, pay a bonus, or make an RRSP contribution changes what you can deduct and when — and the best moves are made before your year-end closes, not in the scramble afterward. Reviewing your position mid-year is what keeps those options open.
Reconciled every month, your books are filing-ready and cheaper to prepare. Rebuilt in a hurry from a shoebox of receipts, they produce a number that's wrong often enough to matter — missed credits, personal expenses left in, transfers coded as revenue. Keep bank, credit-card, and HST records current as you go.

Software reports what happened; it won't tell you what to do about it. A specialist who knows your business structure can flag changes to your instalments, the small business deduction, and your salary-versus-dividend mix while there's still time to act — before the return is filed, not after.
The point is simple: the earlier you look, the more you can change. A review done mid-year gives every decision two quarters to work — the same review in filing season is just a report on choices already made.
“A mid-year review isn't more paperwork. It's the chance to change your tax bill while you still can — deliberately, with the numbers in front of you.”
The right tools cut the manual work — automatic bank feeds, digital receipts, and built-in GST/HST tracking. Paired with a monthly review, the numbers start driving decisions instead of just piling up. We set this up and keep it running as part of every engagement.
If you earn self-employment income in Canada — freelance, contract, gig, or small business — you report it on Form T2125, filed as part of your personal T1 return. Here is what each part covers and the records the CRA expects.
T2125, Statement of Business or Professional Activities, calculates your net business income: gross revenue minus eligible expenses. That net figure flows into your T1 and is taxed at your marginal rate. You are taxed on profit, not revenue — which is exactly why tracking expenses matters.
Complete a separate T2125 for each distinct business activity.
| Category | What you can deduct |
|---|---|
| Home office | % of rent, utilities, and insurance based on workspace size |
| Vehicle | % of fuel, insurance, and maintenance by business km (logbook required) |
| Phone & internet | Business-use portion only |
| Advertising | Website, online ads, platform fees |
| Supplies & software | Tools used to deliver your work |
| Professional fees | Accounting and legal for business |
| Meals & entertainment | 50% of business-related amounts |
Both are calculated on a business-use percentage and both need documentation — a workspace measurement for home office, a mileage logbook for vehicle. The CRA disallows vehicle claims without a log.
Keep all records for six years. Contemporaneous records — kept as you go, not reconstructed in April — are your best defence in a review.
Self-employed individuals file by June 15, but any balance owing is still due April 30. Interest starts May 1 on unpaid amounts.
We map your income and expenses to the right T2125 categories, review for audit risk before filing, and e-file with the CRA.
