The First-Year Freelancer's Tax Checklist
Almost every tax problem self-employed Canadians run into — the terrifying April balance, the shoebox of unsorted receipts, the GST/HST registration letter that arrives months late — traces back to habits that were or weren't built in the first year. Nothing about first-year taxes is difficult; what makes them dangerous is that nobody withholds anything for you anymore, and the consequences of ignoring that arrive twelve months later, all at once. This checklist walks your first year chronologically: what to do in week one, what to set up in month one, what to watch all year, and what to expect the first time you file. Work through it in order and your first tax season becomes an administrative task instead of a crisis.
Week 1 — Set Up the Foundations
☐ Decide your structure (sole proprietor is fine)
For nearly every first-year freelancer, the answer is: operate as a sole proprietor. If you work under your own legal name — "Jane Smith, Consultant" — most provinces require no registration at all. You simply start working. If you want to operate under a trade name ("Maple Design Studio"), that's a provincial business-name registration, typically under $100 and done online in an afternoon.
Incorporation is almost never the right first move. It adds a separate corporate tax return, legal and accounting costs, and payroll complexity — benefits that only start to outweigh costs once income is well above what you spend, which is rarely a year-one situation. Revisit the question in year two or three, not week one.
☐ Don't rush the Business Number
A CRA Business Number (BN) is not a licence to operate — it's an account identifier you need only when you register for a CRA program account: GST/HST, payroll, or import/export. Most new freelancers don't need one on day one. You'll get a BN automatically the day you register for GST/HST, which for most people comes later (see the $30,000 threshold below). One exception worth knowing: some clients ask for a business number on invoices — our business number on invoices guide covers when that matters.
☐ Open a separate bank account
As a sole proprietor operating under your own name, you aren't legally required to have a business account — but you absolutely want a separate account. Every deposit is revenue; every debit is a candidate expense. When your business runs through one dedicated account, your year-end reconciliation is a statement review. When it's mixed with groceries and rent, it's archaeology.
☐ Start the tax-reserve habit with your very first payment
This is the single most important item on the checklist. Every time a client pays you, transfer 25–30% of the gross amount into a separate savings account the same day, and treat that account as untouchable except for tax payments. No employer is withholding anything anymore; this transfer is you doing the employer's job. The full reasoning — including why the percentage covers both income tax and CPP, and why GST/HST is held separately on top — is in our self-employed taxes overview.
Month 1 — Build the Record-Keeping Machine
☐ Capture expenses from receipt #1
Business expenses reduce both your income tax and your CPP contributions, but only if you can substantiate them. The freelancers who lose deductions aren't the ones with ineligible expenses — they're the ones who didn't keep the receipt. Start capturing from the first coffee-shop client meeting: date, vendor, amount, and the tax paid on it. Categorize as you go rather than in April.
☐ Start the mileage log with your first business drive
If you'll use a vehicle for business at all, record your odometer reading now, and log every business trip from the first one: date, start point, destination, purpose, kilometres. The business-use percentage this log produces is what turns your fuel, insurance, and maintenance costs into deductions. A reconstructed log written in April is exactly what CRA reviewers look for. Grab our free CRA mileage log template to start today, and see the CRA mileage log requirements guide for the full rules — including why the famous per-kilometre rate doesn't apply to sole proprietors.
☐ Pick your record system — and stop switching
A spreadsheet works. An app works. What doesn't work is three months in a spreadsheet, two months of "I'll remember," and a photo roll full of unfiled receipts. Pick one system in month one and feed it continuously. If you'd rather not build it yourself: InvoiceFast's Tax tab does this job end-to-end — snap a receipt and AI fills in the vendor, date, totals and GST/HST and suggests the right CRA expense category, while the mileage tracker logs your drives automatically on iOS and Android. Your first 25 expenses and 25 trips are free, which is more than enough to carry a new freelancer through the early months.
☐ Learn what's actually deductible
Home office, the business-use share of your phone and internet, software subscriptions, professional fees, advertising, training, the 50%-limited business meal — the list is longer than most first-year freelancers expect, and every legitimate dollar claimed is roughly 25–45 cents saved depending on your bracket. Read our master list of self-employed tax write-offs once now, so you recognize deductible spending as it happens.
All Year — The Two Numbers to Watch
☐ Track your rolling revenue against the $30,000 GST/HST threshold
You start as a "small supplier" — no GST/HST registration or charging required. That status ends when your taxable revenues exceed $30,000 across four consecutive calendar quarters (or in a single quarter). The threshold is rolling, not calendar-year, and a good first year can cross it faster than expected. Crossing it triggers mandatory registration and charging deadlines measured in days, not months — so keep a running four-quarter total from your first invoice. Registration mechanics, voluntary early registration (and why it can be worth it for the input tax credits), and rate rules by province are covered in our GST/HST guide for freelancers.
☐ Keep your invoicing hygienic
Your invoices are the source records for your income reporting. Two habits make year-end trivial: number invoices sequentially with no gaps, and always show the subtotal separately from any tax charged — because your tax return wants pre-tax income, and your future GST/HST return wants the tax column. The full workflow is in our freelance invoicing guide.
☐ Run a 15-minute quarterly self-check
Every three months, ask: Are all expenses captured and categorized? Is the mileage log current? What's my four-quarter revenue total? Is the tax-reserve account at roughly 25–30% of what I've invoiced? Fifteen minutes per quarter catches drift while it's still fixable.
Your First Tax Season
☐ Meet form T2125
There is no separate "business tax return" for a sole proprietor. Your business income and expenses go on form T2125, a schedule attached to your personal T1 return; its net income flows to line 13500 and is taxed with the rest of your income. If you kept the records above, T2125 is mostly transcription. Walk through it line by line with our T2125 form guide before you file — it shows exactly where invoice subtotals, expenses, vehicle costs and home-office amounts land.
☐ Mark the two deadlines — they are not the same date
Self-employed individuals (and their spouses) have until June 15 to file the T1. But any balance owing is due April 30, and interest starts May 1. The extended filing deadline is not an extended payment deadline — this distinction catches thousands of first-year filers. Practical approach: prepare your return in early April, pay the balance by April 30, file when ready.
☐ Brace for the CPP line
The most common first-filing shock isn't income tax — it's CPP. Employees split CPP contributions with their employer; self-employed people pay both halves, roughly 11.9% of net self-employment income between the basic exemption and the year's maximum pensionable earnings, to an annual maximum of about $7,735 (2026, approximate). A freelancer netting $60,000 owes roughly $6,700 in CPP before income tax is even calculated. This is precisely why the 25–30% reserve exists; if you built it in week one, this line item is already funded.
☐ Decide: software or accountant
A straightforward first year — one revenue stream, standard expenses, no employees, no incorporation — is very manageable in consumer tax software, which walks through T2125 field by field. Hire a professional if you incorporated, crossed six figures, bought significant equipment, or have rental or investment income mixed in. A sole-prop return with T2125 typically runs a few hundred dollars — and the fee is itself deductible next year.
Year 2 — What Changes
☐ Expect instalments if you owed more than $3,000
If your first filing produced a net tax owing above $3,000, the CRA will begin requiring quarterly instalments — due March 15, June 15, September 15 and December 15 — so year two involves paying tax through the year rather than in one spring lump. Paying at least the prior-year amount in equal quarters guarantees no instalment interest.
☐ Settle into a GST/HST rhythm
If you registered during year one, you now have a filing frequency and remittance schedule of your own. Keep every dollar of collected GST/HST out of your operating funds and see our quarterly GST/HST remittance guide for the schedule mechanics and the reconciliation that produces your return.
And that's the arc: the freelancers who find year-two taxes boring are the ones who spent week one of year one setting up accounts and habits. Boring is the goal.
Frequently Asked Questions
Do I need to register a business to freelance?
Usually not at first. A sole proprietor working under their own legal name needs no registration in most provinces; a trade name requires an inexpensive provincial registration. A CRA Business Number only becomes necessary when you register for a program account like GST/HST.
How much should I save for taxes?
25–30% of every gross payment, moved to a dedicated reserve account the day you're paid — closer to 35% at higher incomes. That covers income tax and CPP; GST/HST collected after registration is held separately, in full.
When do I have to start charging GST/HST?
When taxable revenues exceed $30,000 over four consecutive rolling quarters (or in one quarter). Track the running total from your first invoice — the threshold is not a calendar-year figure.
What tax form do freelancers file?
Form T2125, attached to your personal T1 return. File by June 15, but pay any balance owing by April 30 — interest starts May 1 regardless of the filing extension.
Should I hire an accountant in my first year?
Not necessarily. A simple sole-prop year is manageable in tax software. Bring in a professional if you incorporated, crossed roughly six figures, made major equipment purchases, or received CRA correspondence you don't understand.
