Self-Employed in BC? Here’s How to File Your 2025 Tax Return (And Avoid the April 30 Trap)

Published March 2026 · AL Accounting Inc.

If you’re self-employed in BC, your filing deadline is June 15 — but here’s the catch most freelancers discover too late: any taxes you owe are still due by April 30. Miss that date and interest starts accumulating on May 1, even if you haven’t filed yet.

This guide covers what you need to know: deadlines, what to file, what to deduct, and the BC-specific rules that most national accounting blogs miss.


Key Tax Dates for Self-Employed BC Residents in 2026

DeadlineWhat It Covers
April 30, 2026Pay any taxes owed for 2025 — even if your return isn’t complete
June 15, 2026File your 2025 personal income tax return
March 15, June 15, Sept 15, Dec 15Quarterly instalment payments (if required)

The April 30 trap: Estimate what you owe and pay by April 30. File the full return by June 15. The goal is to stop interest from running.

Instalment payments: If you owed more than $3,000 in net tax in 2025 (and at least one of the two prior years), CRA expects quarterly instalments in 2026. This catches many first-year freelancers by surprise in year two.

What Do You Actually File?

All self-employment income goes on your personal income tax return. You also file a Statement of Business or Professional Activities for each business — that’s where you report income, claim expenses, and calculate net earnings. If you’ve crossed the $30,000 GST threshold, you file a separate GST return as well.


Self-Employed Tax Deductions in BC

Claiming what you’re genuinely entitled to is good tax practice; overclaiming raises your audit risk.

Home Office (Especially Valuable in Vancouver)

Deduct a portion of rent, heat, hydro, and internet based on the percentage of your home used exclusively as your office. In Vancouver’s rental market, this can be worth thousands per year.

Vehicle Expenses

Claim the business-use portion of gas, insurance, maintenance, and parking on business trips. A mileage log is mandatory — without one, CRA routinely rejects vehicle claims.

Other Deductions

Office supplies, software, advertising, professional fees, etc.

⚠️ Keep all receipts and records for at least six years. CRA can audit any year within that window.


GST in BC — Two Systems, Not One

British Columbia left the HST in 2013. Self-employed workers in BC deal with two separate tax systems:

  • GST (5%) — federal, registered and remitted through CRA
  • PST (7%) — provincial, registered and remitted through eTaxBC (BC Ministry of Finance)

Most service-based businesses are PST-exempt on their services — but not on goods they sell.

The $30,000 GST Threshold

Once your revenues exceed $30,000 in a single quarter or over any four consecutive quarters, you must register for GST. The clock starts the day you cross that threshold. Registering voluntarily below $30,000 lets you recover GST paid on business expenses — worth considering if you have significant equipment or professional service costs.

CPP: You Pay Both Sides

Employees split CPP 50/50 with their employer. You pay both sides. In 2025, the maximum combined CPP1 contribution is approximately $8,068 (based on a $71,300 earnings ceiling), plus up to $792 in CPP2 on earnings above that ceiling.

The employer-equivalent portion is deductible, reducing your net income for tax purposes.


Common Mistakes Vancouver Self-Employed Workers Make at Tax Time

  1. Waiting until June 15 to think about taxes — interest runs from May 1 on any unpaid balance
  2. Missing instalment payments in Year 2 — a strong first year triggers CRA expectations the following year
  3. Not registering for GST after crossing $30,000 — CRA can assess retroactively
  4. Confusing HST with BC’s two-system setup — BC uses GST + PST separately, not HST
  5. Underclaiming home office — Vancouver rents make this one of the most valuable deductions going; many people leave thousands on the table
  6. No mileage log — vehicle claims are regularly disallowed without one
  7. Mixing personal and business finances — harder to track, easier to flag in an audit

Should You Incorporate?

A BC corporation pays approximately 11% on the first $500,000 of business income versus your personal marginal rate (up to ~53.5% at income above $259,829 in BC). General rule: under ~$80–100K net income, stay sole proprietor; above that, the conversation is worth having.
