Canadian Small Business

Bookkeeping doesn't have to be complicated

Straightforward guidance on organizing receipts, tracking expenses, invoicing clients, and preparing for tax season—written for small business owners in Canada.

The essentials of small business bookkeeping

Whether you run a sole proprietorship or a small corporation, these fundamentals apply.

🧾

Receipt Organization

Consistent filing habits prevent year-end scrambles. The CRA generally requires you to keep supporting documents for six years from the end of the tax year they relate to.

📈

Expense Tracking

Separating personal and business expenses is foundational. A dedicated business bank account and credit card make tracking straightforward and defensible during an audit.

📄

Invoicing Clients

Invoices serve as the primary record of revenue. They should include your business name, HST/GST number if registered, a unique invoice number, and itemized services or goods.

📅

Tax Season Prep

Canadian small businesses report income on a T1 (sole proprietors) or T2 (corporations). Preparing throughout the year rather than in a rush reduces errors and stress.

💸

GST/HST Basics

Once annual revenues exceed $30,000, most businesses must register for GST/HST. Understanding input tax credits (ITCs) ensures you reclaim tax paid on business expenses.

📋

Record Retention

The CRA expects records kept for six years. Digital records are accepted, provided they are stored in a readable format and backed up reliably.
