Year-End Bookkeeping Checklist for Canadian Small Businesses

March 9, 2026

Year-end bookkeeping is the process of closing out your financial records for the fiscal year so your accountant can prepare your tax return. When it is done well, tax filing is fast, your deductions are maximized, and there are no surprises. When it is done poorly — or not at all — you end up paying your accountant to do cleanup work at their hourly rate instead of strategic work that saves you money.

This checklist covers everything you need to do (or have your bookkeeper do) to close your books properly and hand off a clean year-end package.

Why Year-End Bookkeeping Matters

Your accountant needs a complete, accurate set of financial records to:

  • File your tax return correctly (T1 for sole proprietors, T2 for corporations)
  • Maximize your deductions and credits
  • Calculate Capital Cost Allowance (CCA) on assets
  • Identify tax planning opportunities for the coming year
  • Prepare financial statements if needed for lenders or investors

    • The cleaner the records you provide, the less time your accountant spends organizing and the more time they spend on work that actually reduces your tax bill. For small businesses in Sault Ste. Marie, this can mean hundreds or thousands of dollars in savings.

    The Year-End Bookkeeping Checklist

    1. Reconcile All Bank and Credit Card Accounts

    Every bank account and credit card used for business must be reconciled through the last day of your fiscal year. This means the balance in your accounting software matches the balance on your bank statement to the penny.

    Check for:

  • Outstanding cheques that have not cleared
  • Deposits in transit
  • Bank fees or interest charges not yet recorded
  • Transactions that posted in early January but relate to the prior year

    • This is the foundation of everything else. If your reconciliations are off, nothing downstream will be accurate.

    2. Review and Reconcile Accounts Receivable

    Pull an aged accounts receivable report as of your fiscal year-end. This shows every invoice that remains unpaid and how long it has been outstanding.

    Actions to take:

  • Confirm all invoices are accurate and have been recorded
  • Follow up on overdue accounts
  • Identify any amounts that should be written off as bad debts (these are deductible and you may be able to recover the HST)
  • Ensure payments received near year-end are recorded in the correct period

    • 3. Review and Reconcile Accounts Payable

    Pull an aged accounts payable report. This shows what you owe to suppliers as of year-end.

    Actions to take:

  • Confirm all bills are entered, including any received in January that relate to the prior year
  • Verify payment terms and ensure nothing is overdue
  • Match purchase orders to invoices where applicable

    • 4. Record Accrued Expenses

    Accruals are expenses you have incurred but not yet paid or recorded. Common year-end accruals include:

  • Wages earned by employees but not yet paid (e.g., the pay period straddles year-end)
  • Interest on loans
  • Property tax
  • Utilities received but not yet billed
  • Professional fees for year-end work

    • Recording accruals ensures your expenses are matched to the correct fiscal year. This is required under the accrual basis of accounting, which most businesses use.

    5. Record Prepaid Expenses

    If you paid for something in advance that covers the next fiscal year (insurance premiums, annual software subscriptions, rent deposits), the portion that applies to the next year should be recorded as a prepaid expense, not a current-year cost.

    For example, if you paid a $2,400 annual insurance premium in October, only 3 months ($600) applies to the current fiscal year. The remaining $1,800 is a prepaid expense.

    6. Review Fixed Assets and Capital Cost Allowance

    List all capital assets purchased during the year:

  • Vehicles
  • Equipment and machinery
  • Computers and technology
  • Furniture and fixtures
  • Leasehold improvements

    • These are not fully deductible in the year of purchase. Instead, they are depreciated over time through Capital Cost Allowance (CCA). Your accountant will calculate the optimal CCA claim, but your bookkeeper needs to provide a complete list of additions and disposals.

    Also record any assets you sold or disposed of during the year, including the proceeds. This affects your CCA calculations and may trigger a recapture or terminal loss.

    7. Reconcile HST/GST

    Verify that your HST accounts are in order:

  • HST collected on sales matches your sales records
  • HST paid on purchases (ITCs) is supported by valid receipts
  • All HST returns filed during the year are reconciled to your books
  • Any HST balance owing or refundable is recorded correctly

    • If there is a discrepancy between what you filed and what your books show, resolve it before year-end. Your accountant should not be the one discovering HST errors.

    8. Reconcile Payroll

    If you have employees, verify that:

  • Total wages paid match your payroll records
  • CPP, EI, and income tax deductions are accurate
  • Employer contributions are recorded
  • Source deductions remitted to the CRA match what was withheld
  • Any taxable benefits are properly recorded

    • This information feeds directly into your T4 slips, which are due by February 28. Errors here mean amended T4s and potential CRA penalties.

    9. Review Loan and Financing Balances

    For any business loans, lines of credit, or financing arrangements:

  • Confirm the outstanding balance as of year-end matches the lender's statement
  • Separate the principal and interest portions of payments made during the year (interest is deductible, principal is not)
  • Record any new loans taken out during the year

    • 10. Prepare the Adjusted Trial Balance

    The adjusted trial balance is a list of all your accounts and their balances after all year-end adjustments have been made. This is the primary document your accountant uses to prepare your tax return.

    It should include:

  • All asset accounts (cash, receivables, inventory, fixed assets, prepaids)
  • All liability accounts (payables, loans, HST owing, accrued expenses)
  • All equity accounts (owner's equity, retained earnings, draws)
  • All revenue accounts
  • All expense accounts

    • The total debits must equal total credits. If they do not, something is wrong and it needs to be resolved before handing off.

    11. Prepare the Year-End Documentation Package

    Your accountant needs more than just a trial balance. A complete year-end package typically includes:

  • Adjusted trial balance
  • Profit and loss statement for the full year
  • Balance sheet as of year-end
  • Bank reconciliations for the final month
  • Aged accounts receivable and payable reports
  • Fixed asset register with additions and disposals
  • HST reconciliation
  • Payroll summary
  • Loan balance confirmations
  • Copies of any significant contracts or agreements entered during the year
  • Details of any unusual transactions (asset sales, insurance claims, legal settlements)

    • The more complete this package, the less back-and-forth with your accountant and the lower your accounting bill.

    Timeline: When to Start

    | Fiscal Year-End | Start Year-End Bookkeeping | Target Completion | Tax Return Due | |---|---|---|---| | December 31 | Early January | End of February | June 30 (T2) | | March 31 | Early April | End of May | September 30 (T2) | | Any date | Within 2 weeks of year-end | Within 60 days | 6 months after year-end (T2) |

    For sole proprietors with a December 31 year-end, the T1 filing deadline is June 15 (but payment is due April 30). Starting in January gives your bookkeeper enough runway to close the books without rushing.

    Most small businesses in Northern Ontario have a December 31 fiscal year-end. If yours is different, adjust the timeline accordingly.

    Common Year-End Mistakes

    Waiting Until Tax Season

    If you start your year-end bookkeeping in April, you are already behind. Your accountant needs time to review, ask questions, and file. Rushing the process leads to missed deductions and errors.

    Not Reconciling Every Account

    Skipping the credit card reconciliation or ignoring a dormant bank account is how discrepancies survive into your tax return. Reconcile everything, even accounts with minimal activity.

    Forgetting Owner Draws and Personal Expenses

    If you paid personal expenses from your business account, these need to be recorded as owner draws or shareholder loans — not business expenses. Your accountant needs to know the total to calculate your tax correctly.

    Missing Documentation

    The CRA requires you to keep supporting documents for at least 6 years. If you claimed a deduction, you need the receipt. "I know I bought it" does not hold up in an audit. Digital copies are acceptable as long as they are legible and complete.

    Frequently Asked Questions

    How long does year-end bookkeeping take?

    For a small business with clean monthly records, year-end adjustments and package preparation typically take 5 to 10 hours. If the books are behind or have not been reconciled during the year, catch-up work can take significantly longer.

    Can my bookkeeper do year-end bookkeeping, or do I need an accountant?

    Your bookkeeper handles the year-end close — reconciliations, adjustments, and package preparation. Your accountant uses that package to file your tax return and provide strategic advice. Both roles are important, and the handoff between them is where efficiency lives.

    What if my books have not been kept up all year?

    Start with catch-up bookkeeping. Your bookkeeper will reconstruct the year's transactions from bank statements, receipts, and invoices. This is more expensive than maintaining books monthly, but it is necessary before year-end can be completed.

    Do I need to do year-end bookkeeping if I am a sole proprietor?

    Yes. Even though your business income flows through your personal T1 return, you still need organized records to report income and expenses accurately. A proper year-end close ensures you claim every deduction you are entitled to.

    What is the difference between a trial balance and financial statements?

    A trial balance is an internal working document that lists all account balances. Financial statements (income statement, balance sheet, cash flow statement) are formatted reports prepared from the trial balance. Your accountant uses the trial balance; your bank or investors want financial statements.
