Start With Organized Financial Records
Tax preparation is much easier when the underlying records are complete before filing begins. Bank transactions, receipts, invoices, payroll records, sales-tax reports, and bookkeeping should be organized before deductions and tax balances are reviewed.
If the books are incomplete, the tax return can be delayed by reconciliation work, missing documents, incorrect transaction coding, or questions that should have been resolved earlier.
- Bank Statements: Keep statements for business bank accounts for the full reporting period.
- Credit Card Statements: Retain business credit-card statements and supporting transaction records.
- Bookkeeping Records: Reconcile accounts and review uncategorized or unusual transactions.
- Sales Invoices: Maintain records supporting business revenue.
- Expense Documents: Keep receipts, invoices, contracts, and other evidence supporting business expenses.
- CRA Correspondence: Retain Notices of Assessment, statements, installment reminders, and other relevant notices.

Q1 Checklist: January to March
The beginning of the year is often focused on closing the previous calendar year's payroll and information-reporting records while preparing for upcoming personal and business tax work.
- Review prior-year payroll records.
- Confirm employee and contractor information where applicable.
- Prepare required payroll and information slips based on your filing obligations.
- Reconcile payroll source deductions.

- Confirm the filing date that applies to self-employed individuals and their circumstances.

- Reconcile first-quarter bookkeeping.

Important: Filing and payment deadlines can vary by taxpayer, reporting period, business structure, fiscal year-end, and CRA account. Confirm the date that applies to your specific account.
Q3 Checklist: July to September
Mid-year is a useful time to review how the business is performing before year-end decisions become urgent. It is also a good point to confirm whether sales-tax, payroll, or installment obligations have changed as the business grows.
- Review year-to-date revenue and expenses.
- Reconcile bank and credit-card accounts.
- Review GST/HST registration and reporting obligations.
- Review BC PST obligations if the business operates in British Columbia and sells taxable goods or services.
- Check upcoming tax installments if applicable.
- Review payroll accounts and remittances.
- Identify missing receipts or documents before year-end.

Q4 Checklist: October to December
The final part of the year is a useful time to review estimated taxable income, upcoming purchases, compensation, outstanding invoices, inventory, tax installments, and any bookkeeping issues that should be addressed before year-end.
- Review year-to-date profit and expected year-end results.
- Estimate tax obligations where practical.
- Review outstanding customer invoices and receivables.
- Review upcoming business purchases based on genuine business needs rather than tax savings alone.
- Review payroll and shareholder transactions where applicable.
- Count inventory if required for the business.
- Resolve bookkeeping problems before the year closes.
- Review whether professional tax planning is appropriate before major transactions are completed.
Filing Requirements Depend on Business Structure
A sole proprietor and an incorporated company do not file in the same way. The reporting schedule also changes depending on payroll, GST/HST registration, fiscal year-end, sales-tax reporting frequency, and other account-specific factors.
| Business / Account Type | Typical Filing Consideration | What to Confirm |
|---|---|---|
| Sole Proprietorship | Business income is generally reported with the owner's personal tax return. | Personal filing and payment dates that apply to the owner. |
| Corporation | The corporation files its own T2 corporate income tax return. | Corporate fiscal year-end, filing deadline, and balance due date. |
| GST/HST Account | Reporting may be monthly, quarterly, or annual. | Reporting period and payment due date assigned to the account. |
| Payroll Account | Payroll deductions may require recurring remittances and annual information reporting. | Remitter type, due dates, and year-end slip requirements. |
Monthly and Quarterly Tax Tasks
Many tax problems begin long before the annual return is filed. Payroll, GST/HST, PST, installment payments, bookkeeping, and other obligations may require attention throughout the year.
- Reconcile bank and credit-card accounts.
- Review unpaid invoices and supplier bills.
- Reconcile payroll records where applicable.
- Review GST/HST and PST collected and paid.
- Confirm upcoming remittance dates.
- Review owner withdrawals, shareholder transactions, or other unusual entries.
- Keep supporting documents attached to transactions where possible.

Review Tax Installment Requirements
Some individuals and corporations may be required to make tax installments during the year rather than paying the entire balance when a return is filed.
The amount and schedule depend on the taxpayer's circumstances and CRA requirements. Review CRA installment reminders and confirm the appropriate payment method and date instead of relying only on a general calendar.
Setting aside tax cash separately can make upcoming payments easier to manage, particularly for businesses with fluctuating income.
Keep Documentation for Business Deductions
A deduction should be supported by records that show what was purchased, the amount, the date, and the business purpose. The exact documentation required can vary depending on the expense.
- Vehicle Expenses: Maintain records supporting business use and applicable vehicle costs.
- Home Office: Keep relevant occupancy and operating-cost information where a business-use-of-home claim applies.
- Meals and Entertainment: Keep the receipt and enough information to explain the business purpose.
- Equipment: Retain purchase invoices and records for capital assets.
- Professional Fees: Keep invoices for accounting, legal, consulting, and other professional services.
- Travel: Maintain receipts and documentation showing the business purpose of the trip.
Plan Tax Payments Before Filing Day
Businesses should not have to discover every tax obligation only after the return has been completed. Regular bookkeeping and periodic tax estimates can provide earlier visibility into potential balances.
When payments are required, use an accepted payment method for the relevant government account and verify that the correct account number and reporting period are being credited.
Year-End Tax Planning Checklist
Year-end planning should focus on legitimate business and tax decisions supported by accurate records. It should not be based on spending money simply to create a deduction.
- Review accounts receivable.
- Review accounts payable.
- Review inventory where applicable.
- Reconcile payroll and source deductions.
- Review business asset purchases and disposals.
- Review shareholder or owner transactions.
- Confirm GST/HST and PST balances.
- Review estimated taxable income.
- Identify missing documents or unreconciled accounts.
- Discuss significant transactions with the appropriate tax, accounting, or legal professional before implementation.

Frequently Asked Questions
What should a small business keep for tax preparation?
Keep bookkeeping records, bank and credit-card statements, sales invoices, expense receipts, payroll records, GST/HST or PST records where applicable, asset purchase documents, and relevant CRA correspondence.
Are all Canadian small-business tax deadlines the same?
No. Deadlines vary depending on whether the business is incorporated, the fiscal year-end, payroll-remitter status, GST/HST reporting period, and other account-specific requirements.
Can business receipts be stored digitally?
Businesses commonly maintain electronic records, but the documents should remain clear, complete, accessible, and connected to the relevant transaction.
When should a business start year-end tax planning?
Planning is most useful before year-end decisions have already been completed. Businesses with significant purchases, owner compensation, corporate transactions, investments, or other major changes may benefit from reviewing the tax impact earlier.
What if my bookkeeping is behind when tax season arrives?
The records may need to be reconciled and cleaned up before reliable tax information can be prepared. Starting the cleanup earlier usually gives more time to resolve missing documents and transaction questions.
