Bookkeeping Checklist for Ontario Small Businesses
Running a small business in Ontario involves more than tracking sales and paying bills. Accurate bookkeeping helps business owners understand cash flow, monitor expenses, prepare tax filings and maintain organized financial records.
For Ontario business owners, Sukhraj Atwal provides accounting and bookkeeping support designed to help businesses keep their financial records organized and up to date.
Use the following checklist to stay on top of your bookkeeping throughout the year.
1. Separate Business and Personal Finances
Keep your business banking separate from your personal finances.
- Open a dedicated business bank account.
- Use a business credit card for business purchases.
- Avoid mixing personal and business expenses.
- Record owner withdrawals and contributions properly.
- Reconcile business accounts regularly.
Keeping separate records makes it easier to track business activity and prepare accurate financial statements.
2. Record All Business Income
Record every source of business income, including:
- Customer payments
- Credit and debit card sales
- Online payments
- Cash sales
- Deposits
- Other business revenue
CRA guidance states that income records should include the date, amount and source of income, supported by appropriate documentation.
3. Track Business Expenses
Keep receipts and invoices for business expenses such as:
- Office supplies
- Rent
- Utilities
- Advertising and marketing
- Software subscriptions
- Professional fees
- Insurance
- Business travel
- Vehicle expenses
- Equipment
- Telephone and internet costs
Proper records can help identify deductible expenses and support claims if the CRA reviews your business records.

4. Reconcile Your Bank Accounts
Compare your bookkeeping records with your actual bank and credit-card statements.
Check for:
- Missing transactions
- Duplicate transactions
- Incorrect amounts
- Unrecorded bank fees
- Outstanding payments
- Deposits that have not been recorded
Monthly reconciliation can help identify bookkeeping errors before they become larger problems.
5. Keep GST/HST Records Organized
If your business is registered for GST/HST, maintain records that allow you to determine the GST/HST collected and the GST/HST paid on eligible business purchases.
Keep:
- Sales invoices
- Purchase invoices
- Receipts
- GST/HST calculations
- Supporting documentation for input tax credits
- Copies of filed GST/HST returns
CRA guidance says businesses generally need to retain GST/HST records for six years from the end of the relevant year.
6. Review Accounts Receivable
Don’t only record sales—monitor whether customers have actually paid.
Create a regular accounts-receivable review to identify:
- Outstanding invoices
- Overdue accounts
- Customers approaching payment deadlines
- Long-outstanding balances
Following up on unpaid invoices can improve cash flow and help you understand how much money is actually available to the business.
7. Track Accounts Payable
Maintain a list of bills your business needs to pay.
Track:
- Supplier invoices
- Due dates
- Amounts owing
- Payments made
- Recurring expenses
This helps prevent missed payments and gives you a clearer picture of upcoming cash requirements.
8. Keep Payroll Records
If you have employees, payroll bookkeeping should include records of wages, hours worked and applicable deductions.
CRA requirements include records of amounts withheld for income tax, CPP and EI, along with required employee and payroll documentation.
For 2026 payroll calculations, CRA provides updated payroll deduction tables and its Payroll Deductions Online Calculator.
9. Track Business Assets and Equipment
Keep records for significant purchases such as:
- Computers
- Machinery
- Vehicles
- Furniture
- Tools
- Office equipment
Record the purchase date, cost and relevant supporting documents. Proper asset records can help when preparing financial statements and calculating applicable tax deductions.
10. Back Up Your Bookkeeping Records
Don’t rely on a single copy of your financial records.
Use secure digital storage and regular backups for:
- Accounting files
- Invoices
- Receipts
- Bank statements
- Payroll records
- Tax documents
- Financial reports
CRA’s current guidance recognizes electronic record keeping and recommends appropriate systems, backups and accessible records.
11. Review Your Financial Statements
At least monthly, review key reports such as:
Profit and Loss Statement:
Shows revenue, expenses and profitability.
Balance Sheet:
Shows assets, liabilities and equity.
Cash Flow:
Helps you understand money coming into and leaving the business.
These reports can help business owners identify trends and make better-informed financial decisions. CRA also notes that organized records can help businesses understand their financial position, compare performance and prepare budgets and forecasts.
12. Keep Records for the Required Period
Don’t throw away bookkeeping documents immediately after filing your taxes.
CRA generally requires business records to be retained for at least six years from the end of the last tax year to which they relate, subject to specific exceptions and circumstances.
Keep supporting documentation such as:
- Invoices
- Receipts
- Bank statements
- Contracts
- Deposit records
- Financial statements
- Tax returns
- GST/HST records
- Payroll records
