Year-end is not a March problem. The Canadian owner-operators whose year-ends are calm are the ones who treat the last two months of the fiscal year as the work, and who hand their accountant a clean, closed set of books by mid-January. Everyone else pays — in CPA billable hours, in CRA late-filing penalties, in the quiet cost of decisions made on stale numbers.
This is the complete year-end bookkeeping checklist for Canadian owner-operators with a corporation. It is written for a calendar-year fiscal end (December 31), which is the most common in Canada, but every step applies at any year-end with the months shifted accordingly. Work through it in order. The steps compound; skipping one forces rework two or three steps later.
Why year-end preparation matters
Three concrete reasons, in order of cost.
The CRA has hard deadlines. The T2 corporate tax return is due six months after fiscal year-end. Tax owing is due earlier — two months after year-end for most corporations, three months for Canadian-controlled private corporations eligible for the small business deduction. T4 and T4A slips are due the last day of February. GST and PST filings run on their own schedules. Miss any of these and the penalties and interest compound.
The CPA bill depends on the handoff. CPAs charge by the hour. A clean year-end package — reconciled books, a trial balance that ties to sub-ledgers, and supporting schedules — means the accountant moves straight to tax strategy and the T2. A messy handoff means the accountant does the bookkeeper's job first at accountant rates. Most owner-operators who switch to a disciplined monthly rhythm see their year-end CPA engagement fees drop materially in the first year.
Tax planning has a window. The final weeks before year-end are when most legitimate tax-planning moves still work — capital purchases, bonus declarations, dividend versus salary choices, RRSP and TFSA contributions for shareholders, charitable donations. These decisions need current numbers. A ledger that's six weeks behind cannot support a tax-planning conversation in mid-December.
When to start
For a calendar-year business, the year-end conversation starts in early November. Not because anything is urgent at that point — because by early November the first ten months of the year are set in the books, the last two months are reasonably predictable, and any decisions that can still be made have enough runway to execute cleanly.
A reasonable timeline for a December 31 year-end:
| Window | What happens |
|---|---|
| Early November | Year-end planning meeting with bookkeeper and CPA; tax-planning decisions scoped |
| Mid-November to mid-December | October and November books closed; asset register reviewed; tax-planning decisions executed |
| Mid-December to early January | December transactions coded, credit card statements closed, year-end expenses booked |
| First two weeks of January | Final reconciliations; accrued expenses, deferred revenue, and adjusting entries posted |
| Mid-to-late January | Year-end package assembled and delivered to CPA |
| February | CPA works on T2; T4 and T4A slips filed by February 28 |
| March to June | T2 filed (by June 30 for December year-end); tax owing remitted |
If the business has been on monthly bookkeeping all year, this timeline is routine. If not, the catch-up work extends the left side of the timeline and compresses everything else.
The ten-step checklist
1. Reconcile every bank and credit card account to the statement
Every bank account, every credit card, every line of credit, every merchant processor. Reconciled to the penny, against the monthly statement, for every month of the fiscal year. Not "reviewed." Reconciled.
This is the foundation. A single unreconciled month will hide duplicated transactions, missed receipts, misclassified transfers, and the occasional fraudulent charge nobody noticed in July. If you are running on QuickBooks Online or Xero, the bank feed is a convenience, not a reconciliation — the monthly statement is still the source of truth.
By mid-December, every month through November should be reconciled. The December reconciliation happens in the first full week of January, once the final statements post. If any of this feels like an unreasonable amount of work, monthly bookkeeping is what keeps it from being a year-end event.
2. Collect outstanding invoices and clean up AR
Pull an accounts receivable aging as of the current date. Anything past 60 days is a conversation; anything past 90 is a decision.
Before year-end, make those calls. The goal is not just cashflow — the goal is an AR balance sheet line you believe in. Invoices that will not be collected should be written off before year-end so they do not drag into next year's revenue. Your CPA will thank you, and your taxable income will reflect what actually happened.
While you are in the AR ledger, check two details. First, every invoice marked paid actually has a corresponding deposit in the bank. Second, no customer has paid you twice. Both happen more often than owners expect, and both are easier to fix in December than in April.
3. Capture every business expense with documentation
Receipts, mileage, home office if you claim it, subscriptions paid on a personal card, reimbursements owed to you by the corporation. If it was a business expense and it lives in a shoebox, a drawer, or an email inbox, now is when it joins the books.
Specifics that catch people out:
- Mileage. If you use a personal vehicle for business, you need a log. A dated, per-trip record with kilometres and purpose. Retroactive reconstruction from a calendar is acceptable; "I drove about 8,000 km" is not.
- Home office. Calculate the square footage or room percentage and apply it to utilities, internet, insurance, and mortgage interest or rent. Do this once, write it down, and it takes minutes every year after.
- Personal cards used for business. Reimburse them through the corporation with a proper expense report, or book them as shareholder contributions. Don't leave them hanging.
- Subscriptions. Software, memberships, professional dues. These are easy to miss because they auto-charge. Pull twelve months of card statements and scan for anything recurring.
The CRA's test for a deductible expense is that it was incurred to earn business income, it is reasonable, and you can document it. The receipt is the documentation.
4. Review payroll totals and prepare T4s and T4As
Payroll runs through software — Wagepoint, Payworks, Deluxe, QuickBooks Payroll — but the year-end reconciliation still needs eyes on it. Before the first week of January:
- Confirm every employee's year-to-date earnings, tax, CPP, and EI match the sum of their pay stubs.
- Confirm every T4A recipient (contractors paid over $500, board directors, certain beneficiaries) is accounted for.
- Resolve any discrepancies with the payroll provider before slips are filed.
T4s and T4As are due to employees and to the CRA by the last day of February. The filing window is short; the preparation window is November through January. If there are contractor payments you are unsure about, settle the classification question with your CPA before the slips go out — once they are filed, amendments are a bigger job than getting them right the first time.
If payroll has been a grudge task, this is the piece to fix first. See payroll management.
5. File GST and PST up to year-end
GST/HST and BC PST filings should be caught up through the most recent period before year-end preparation begins. Filing returns out of sequence is always more painful than filing them on schedule, and a late period makes the year-end numbers harder to trust.
Three things to verify while you are in the GST/PST ledger:
- Input tax credits claimed only on legitimate business purchases with GST-registrant vendors.
- PST remitted on taxable goods and services where BC requires it (the list changes; if you are unsure, ask).
- No double-claiming of GST on items that were already expensed gross.
For the complete GST and PST mechanics, see the practical guide to GST and PST filing in BC. For what our service covers, see GST and PST filing.
6. Record capital asset additions and disposals
Capital asset purchases during the year should be captured on the balance sheet, not expensed. Equipment, vehicles, leasehold improvements, the computer you bought in June. Your CPA will handle the capital cost allowance (CCA) calculation at year-end, but the bookkeeping sets them up for it.
Equally important — disposals. If you sold, traded, or scrapped a capital asset, that is a transaction with tax consequences. The gain or loss needs to be calculated against the asset's undepreciated capital cost, which means your CPA needs both the original purchase record and the disposal record. A disposal recorded only as "sold truck — $12,000" is missing half the story.
Walk through your fixed asset register line by line. Anything listed that you no longer own? Dispose of it. Anything you own that is not listed? Add it. Confirm the capitalisation policy (most businesses use a $500 or $1,000 threshold below which items are expensed) and make sure every transaction was treated consistently.
7. Reconcile intercompany transactions for HoldCo and OpCo structures
If you run a holding company and an operating company, the intercompany transactions between them need to reconcile to the cent, in both sets of books, by year-end. Management fees charged by HoldCo to OpCo. Dividends declared and paid. Shareholder loans advanced and repaid. Rent, if real estate sits in HoldCo.
The pattern we see: OpCo's books show $48,000 in management fees paid to HoldCo. HoldCo's books show $50,000 received. Each has been closed by a different bookkeeper, at a different time, without a reconciling entry. This is the kind of thing CPAs find in April that could have been fixed in December for a tenth of the cost.
If intercompany coordination is a recurring headache, fractional controller is often the right answer — not more bookkeeping hours, but a single senior person holding both sets of books to the same standard.
8. Post accrued expenses and deferred revenue
Accrue expenses that have been incurred but not yet invoiced or paid. Typical examples: bonuses declared but not yet paid, professional fees (legal, accounting) earned but not yet invoiced, utilities consumed but not yet billed, interest accrued on loans.
Defer revenue that has been received but not yet earned. Typical examples: customer deposits for work to be done next year, annual subscription payments received in December for services delivered through the following year, retainer payments not yet worked against.
The cut-off principle is the guide: transactions belong in the period they relate to, not necessarily the period they hit the bank. Adjusting entries at year-end align the two.
For owner-operators who have never dealt with accruals before, this step is where a fractional controller earns their keep — the judgement about what to accrue, what not to, and how much, needs a senior eye.
9. Review AR and AP aging and adjust where needed
Pull the final AR and AP aging at year-end. Three actions:
- Write off uncollectable AR. Invoices older than 120 days where there is no realistic prospect of payment should be written off, not carried as a receivable. The write-off reduces taxable income in the correct year.
- Confirm AP reflects actual obligations. Reconcile the AP ledger against vendor statements for all significant vendors. Stale AP balances (invoices long since paid but not cleared) create balance sheet noise and confuse the CPA.
- Document any unusual items. Large disputed invoices, open credit notes, or prepayments against future services all need a note so the CPA knows how to treat them.
10. Assemble and deliver the CPA handoff package
When the books are closed, your CPA should receive a package, not a dump. At minimum:
- Trial balance as of year-end
- Balance sheet and income statement, comparative to the prior year
- General ledger for the full year
- Bank reconciliations for all months, with final statements
- AR and AP aging detail
- Fixed asset register with additions and disposals noted
- Payroll summary and confirmation T4/T4A filings are on track
- GST and PST filing history
- A short written note covering anything unusual — a large one-time transaction, a change in ownership, a material accounting policy change
A package like this lets a CPA move straight to the work that needs their judgement — tax planning, year-end adjusting entries, and the T2 corporate tax return — rather than burning hours sorting the books first. Our year-end preparation service is this package, every year, without the owner lifting a pen.
Common mistakes that delay year-end
Five patterns delay most year-ends. All of them are preventable.
Skipping reconciliations mid-year. Owners who reconcile once at year-end pay twice — once for the catch-up and once for the time it takes the CPA to sort through the result. Reconcile monthly.
Leaving personal expenses to year-end. Personal purchases on the business card, business purchases on the personal card, reimbursements never filed. All of it needs to be sorted before the books close. Sort it monthly.
Not documenting as you go. Receipts lost, mileage unlogged, home-office percentage uncalculated, subscription lists incomplete. Every piece of undocumented expense is a deduction lost or a CRA documentation gap.
Ignoring intercompany. Owners with HoldCo and OpCo who close each set of books separately without reconciling the two. The year-end fix is always harder than the quarterly habit.
Not talking to the CPA until January. Tax planning happens before year-end, not after. Owners who wait until January to call their CPA miss the window for bonus declarations, capital purchases, and dividend-vs-salary decisions.
What your CPA needs from you
A short, explicit list. Hand this to your bookkeeper in October and the year-end preparation should return every item.
- Trial balance at fiscal year-end.
- Comparative balance sheet and income statement (current year vs prior year).
- General ledger for the full fiscal year, exportable.
- Monthly bank reconciliation reports with matching bank statements.
- AR aging as of year-end, with a note on any write-offs.
- AP aging as of year-end, with a note on any disputed or unusual items.
- Fixed asset register with additions, disposals, and current capitalisation policy.
- Payroll year-end summary (PD27 equivalent or direct report from payroll software) confirming T4 and T4A status.
- GST and PST filing history for the fiscal year, including copies of filed returns.
- Shareholder loan reconciliation (opening balance, additions, repayments, closing balance).
- Intercompany balance confirmation (for HoldCo/OpCo structures).
- A written memo covering anything unusual — large one-time transactions, changes in ownership, new loan agreements, material accounting policy changes.
Given this package, most CPAs can produce a T2 and management letter without asking a single bookkeeping question.
