Preparing to File: What You Need Before Starting
Key Documents and Information to Gather
- Business number (BN): Issued by the Canada Revenue Agency (CRA)
- Financial statements: Including income statement and balance sheet
- Receipts for expenses: Office, equipment, travel, advertising, etc.
- Records of revenue: Sales invoices, bank statements, e-commerce revenue reports
- Employee-related documents: T4 slips, payroll summaries if you have staff
- Previous years’ tax returns: For consistency and reference
Accounting Methods: Accrual vs. Cash
Choose the right accounting method for your business:
- Cash method: Only record income and expenses when cash changes hands. Suitable for small, cash-based businesses.
- Accrual method: Record income when earned and expenses when incurred, regardless of when money changes hands. This is required for incorporated businesses and offers a clearer picture of your financial health.
