Why Year-End Prep Starts in December (Not April)
The most expensive accounting bills happen when business owners arrive at their accountant's office in March with a box of unsorted receipts and a Xero file they haven't touched since October.
Your CPA's job is to prepare and file your tax return — not to reconstruct your books. Every hour they spend on cleanup is an hour at $200–$400 per hour that you're paying for work that could have been prevented.
A solid year-end close done in December or January means your CPA receives a clean, organized package and files your return faster, cheaper, and more accurately. Here's the complete checklist.
December: Pre-Year-End Actions
✅ Review and Reconcile All Bank and Credit Card Accounts
Before December 31st, ensure every bank account and credit card is reconciled through the current month. Any unreconciled transactions are errors or missing entries that will compound your accountant's work.
Check: Do your closing balances in your accounting software match your actual bank statements? Every account, every month of the year.
✅ Review Accounts Receivable (AR) Aging
Pull your AR aging report. For any invoices outstanding over 90 days:
- Send a final collection notice
- Determine whether any should be written off as bad debts (deductible for tax purposes)
- Confirm the balance matches your customer records
✅ Review Accounts Payable (AP)
Confirm all outstanding vendor invoices are entered and accurately reflect what you owe. Accrue any December expenses that haven't been invoiced yet (e.g., December contractor work invoiced in January — belongs in this year's P&L).
✅ Inventory Count (If Applicable)
If you carry physical inventory, you must take a physical count on December 31st (or as close as possible). The year-end inventory value is used to calculate your Cost of Goods Sold and is required for your tax return.
Document: item descriptions, quantities, and unit costs. Your bookkeeper will calculate ending inventory value using your elected costing method (FIFO, weighted average).
✅ Reconcile Payroll
Ensure all payroll runs for the year are recorded, all CRA remittances have been made and recorded, and year-to-date payroll totals by employee match your payroll software.
You'll need these numbers to prepare T4 slips in February.
✅ Collect All Year-End Receipt Documentation
December is the month to hunt down missing receipts and documentation. Key items:
- Mileage logs for vehicle expenses
- Home office expense documentation (square footage calculation, utility bills)
- Business meal and entertainment receipts with business purpose noted
- Capital equipment purchase invoices
January: Year-End Close Actions
✅ Make Year-End Accruals and Adjustments
Accrued expenses: Record any expenses incurred in the current year but not yet invoiced (e.g., December bank fees posted in January, unbilled professional services).
Prepaid expenses: If you paid for a 12-month subscription or insurance policy, only the portion relating to the current year should be expensed. The remainder is a prepaid asset on your balance sheet.
Depreciation: Your accountant will determine your Capital Cost Allowance (CCA) — the Canadian equivalent of depreciation — for any eligible assets. Make sure all asset purchases during the year are documented with invoice details.
Owner draws and shareholder loans: Ensure all owner withdrawals and contributions are properly classified — whether as salary, dividends, loan repayments, or capital contributions.
✅ Reconcile GST/HST
Pull your GST/HST payable account and confirm:
- The balance matches your CRA account (log in to My Business Account)
- All returns filed during the year are recorded in your books
- Any ITCs claimed are supported by proper documentation
December 31st GST/HST adjustments may be needed if your account is off.
✅ Confirm Your Year-End Loan Balances
For any business loans, lines of credit, or shareholder loans, confirm the outstanding balance as of December 31st matches the statements from your lenders. Record any accrued interest payable.
✅ Close the Year in Your Accounting Software
In QuickBooks Online or Xero, set a "closing date" password for the year you're closing. This prevents accidental edits to historical data after your CPA has reviewed it.
February: CPA Handoff Deliverables
By February, your bookkeeper should prepare and deliver the following to your CPA:
| Document | Purpose | |---|---| | Profit & Loss Statement (Jan 1 – Dec 31) | Income tax calculation base | | Balance Sheet (as of Dec 31) | Asset, liability, equity snapshot | | General Ledger | Transaction-level audit trail | | Bank and CC reconciliation statements | Confirms all accounts tied out | | Accounts Receivable aging | Outstanding customer balances | | Accounts Payable aging | Outstanding vendor balances | | Fixed asset schedule | Depreciation and CCA calculation | | Payroll summary by employee | T4 preparation support | | GST/HST reconciliation | Confirm CRA compliance | | Shareholder loan continuity | Opening balance + activity + closing |
T4 and T4A deadline: Must be issued to employees and filed with CRA by February 28 (or March 2 in non-leap years).
Common Year-End Mistakes to Avoid
1. Recording personal expenses as business expenses Year-end is when CRA auditors look for exactly this. Review all expenses and ensure they have a legitimate, documented business purpose.
2. Missing capital asset additions Any equipment, vehicle, or computer over the $500 threshold should be capitalized (not expensed immediately) and added to your fixed asset schedule for CCA purposes.
3. Forgetting to accrue the owner's management fee or bonus If your corporation pays a management fee or bonus to the owner-operator, it must be paid (or at minimum accrued and paid within 180 days of year-end) to be deductible in the current year.
4. Not reconciling the shareholder loan account The CRA scrutinizes shareholder loan accounts closely. If the account has a debit balance (you owe the corporation) at year-end for more than two consecutive years, it may be deemed a taxable benefit.
