Tax season checklist for Canadian small business owners

Prepare for tax season in Canada with this simple checklist for small business owners. Learn CRA requirements, what documents to gather, and how to maximize deductions.

Updated this week

Tax season can feel overwhelming, but a little preparation goes a long way. Whether you’re a sole proprietor, freelancer, or independent business owner in Canada, getting organized early can help you file accurately, avoid delays, and reduce stress.

This checklist walks you through 3 essential steps:


Tax season prep checklist

Step 1: Know your CRA requirements

Before you gather paperwork, make sure you understand the basics of what the CRA expects from your business.

GST/HST obligations

  • If your business earns more than $30,000 in revenue over the last 4 consecutive calendar quarters, you must:

    • Register for Goods and Services Tax (GST)/Harmonized Sales Tax (HST)

    • Collect tax from clients

    • File and remit payments to the CRA

  • You may be eligible for the Quick Method, which lets you remit a fixed percentage of collected GST/HST instead of tracking every input tax credit. This option can be helpful for businesses with taxable sales under $400,000, but may not be ideal if you have high business expenses.

Income reporting forms

  • T2125 – Statement of Business or Professional Activities: Used by self-employed individuals to report business income and expenses

  • T4A slips: You may receive these from clients who paid you during the year and must include them when filing


Step 2: Gather essential documents

Having your records ready ahead of time can significantly speed up tax filing.

Income records

  • Invoices or statements from clients

  • T4A slips issued to you

Expense documentation

  • Receipts for deductible expenses such as office supplies, advertising, travel, software, etc.

  • Home office expense records: Calculate the percentage of your home used for business

  • Vehicle mileage log: Track dates, destinations, kilometers driven, and business purpose

Financial summaries

  • Profit and loss (P&L) report, or a detailed income and expense record

  • Registered Retirement Savings Plan (RRSP) contribution statements: Contributions made by March 1, 2026 may reduce taxable income for the tax year

Step 3: Maximize deductions and credits

Understanding available deductions can help lower your taxable income. Common examples include:

  • Capital Cost Allowance (CCA): Depreciation for business assets like computers, furniture, or vehicles

  • Business use of home expenses: A portion of rent, utilities, insurance, or property taxes based on workspace usage

  • Professional development and memberships: Courses, certifications, and industry memberships directly related to your business

Final tips

Plan ahead for next year. If personal and business finances were mixed this year, consider opening a separate business bank account to make tracking income and expenses easier going forward.

With a clear understanding of CRA requirements, organized records, and awareness of deductions, you’ll be well positioned for a smoother tax season. If you’re unsure about any step, a qualified tax professional can help you file with confidence.
