What should be on a freelancer tax season checklist?

Three phases. Off-season (now): track expenses as they happen, separate business and personal money, set aside a percentage of every invoice for tax, and pay any required instalments (September 15 and December 15, 2026). January–February: gather slips, 12 months of statements, your kilometre log, and home office numbers, then total everything by T2125 category. Filing (spring 2027): complete the T2125, claim RRSP contributions up to your Notice of Assessment limit, file any GST/HST return, and file by June 15, 2027 — but pay any balance owing by April 30, 2027.

When is the tax filing deadline for self-employed Canadians?

For the 2026 tax year: self-employed filers (and their spouses) have until June 15, 2027 to file, but any balance owing is due April 30, 2027 — interest starts after that date even though the filing deadline is later. GST/HST registrants with a December year-end who file annually also file by June 15 with payment due April 30.

What documents does a freelancer need to file taxes in Canada?

Income records for every client (invoices, platform statements, T4A slips if issued), 12 months of bank and credit card statements, receipts organized by T2125 expense category, a kilometre log if you claim vehicle expenses, home office measurements and costs, RRSP contribution receipts, your prior-year Notice of Assessment, and — if registered — your GST/HST records including input tax credits.

Should freelancers wait until April to start their taxes?

No. The expensive mistakes — missed deductions, no kilometre log, unclaimed home office, a surprise GST/HST registration requirement — happen during the year, not at filing time. An hour of setup now (expense tracking, separate accounts, a tax set-aside) turns filing season into a formality.

Freelancer Tax Season Checklist for Canada: File Your 2026 Return

Tax season isn't really a season. For freelancers, the return you file in spring 2027 is being written right now — in whether you're logging kilometres, keeping receipts, and setting money aside. This checklist covers all three phases.

1 The Off-Season Checklist (Do These Now)

☐ Track expenses as they happen. The free expense tracker puts every expense on the correct T2125 line, with per-province GST/HST extraction, entirely on your device.
☐ Separate business and personal money. One business account, one card — the simple setup.
☐ Set aside tax from every invoice. Run your expected income through the self-employed tax calculator and move that percentage into a separate account every time you're paid.
☐ Pay instalments if they apply to you. Required when net tax owing exceeds $3,000 ($1,800 in Quebec) this year and in one of the two prior years. Remaining 2026 dates: September 15 and December 15. Run the requirement check.
☐ Start (or reconstruct) your kilometre log if you drive for work — vehicle expenses need one.
☐ Watch the GST/HST threshold. One quarter over $30,000, or four consecutive quarters totalling over it, and registration is mandatory — check your position.

2 The January–February Checklist (Gather)

☐ Income: every invoice, platform payout report, and any T4A slips clients issue.
☐ Statements: 12 months of business bank and credit card statements.
☐ Receipts: sorted by T2125 category — the afternoon system, or run statements through the categorizer.
☐ Vehicle: total kilometres and business kilometres from your log.
☐ Home office: workspace size vs. home size, plus rent/utilities/internet totals.
☐ Capital purchases: computers, cameras, equipment — these go through CCA (Area A), not straight expensing.
☐ RRSP room: the deduction limit printed on your latest Notice of Assessment — how it works for freelancers.
☐ Last year's return and NOA for carry-forwards (unused home office amounts, losses, RRSP room).

3 The Filing Checklist (Spring 2027)

☐ Complete the T2125 — the free generator fills it line by line from your totals, or follow the step-by-step guide.
☐ Claim the deductible half of CPP (line 22200, via Schedule 8 — software does this automatically).
☐ Claim RRSP contributions up to your NOA limit.
☐ File your GST/HST return if registered (annual filers with a December year-end: return due June 15, payment due April 30).
☐ Pay any balance owing by April 30, 2027 — interest starts after this date even though the filing deadline is later.
☐ File by June 15, 2027 (the self-employed filing deadline for the 2026 return).
☐ After filing: read your NOA, archive records for 6 years, and check whether instalments apply next year — the post-filing checklist.
