They record transactions, check the bank balance, and treat the year end as when the books become real. That works until the year end, when twelve months of ambiguity must be resolved at once by someone who was not there. **Quick answer:** A [month-end close](https://www.everstonecpa.com/month-end-close) is a short, repeatable routine that brings a set of books to a reliable state: accounts reconciled, revenue and costs in the right period, sales tax and payroll agreed, and the period locked. Done monthly, it turns the corporate year end into a review. Closing means locking the period, not finishing the data entry. ## Key takeaways - Closing means locking the period, not just finishing the data entry. - Reconcile every account the business touches, then agree the sales tax and payroll balances. - Twelve closed months produce a year end that is reviewed rather than rebuilt. - Closed months also give you comparatives, which is what makes the numbers useful. ## What “closing” actually means A period is closed when every account is reconciled to an external record, every transaction sits in its period, and the period is locked so nothing can be posted into it. The lock is almost always skipped, yet it gives the close its value. Without it, a transaction dated last March can be added in November, and your comparatives, GST/HST returns and interim numbers quietly stop agreeing. **Want these claims documented properly?** Our monthly bookkeeping, from $325 a month, keeps every deduction backed by a receipt and a reconciled account before the CRA asks.

Complete the transactions Import and code everything to the cut-off, clear the uncategorized account to zero, and enter bills and invoices dated in the month even if issued later. On the accrual basis, the work date matters, not the paperwork date — see [cash versus accrual accounting](https://www.everstonecpa.com/blog/cash-vs-accrual-accounting-canada). ### 2. Reconcile every account Each bank account, credit card, payment processor, and any loan or lease with a statement. The closing balance must agree and every reconciling item must be explainable. Items outstanding over two months are usually errors, not timing. See [why bank reconciliation matters](https://www.everstonecpa.com/blog/bank-reconciliation-why-it-matters). ### 3. Agree the sales tax accounts The GST/HST collected and input tax credit balances should agree to what your filings say, and the difference between them should be the amount you actually owe or are owed. If the two never agree, one of them is being posted incorrectly, and finding that at month end is far cheaper than finding it during a review of a filed return. ### 4. Agree payroll Gross pay, source deductions and employer portions should agree to payroll records, and remittances should clear the payable. A balance left after the remittance date means a missed remittance or a wrong entry. See [payroll remittances and the RP account](https://www.everstonecpa.com/blog/payroll-remittances-canada-rp-account). ### 5. Review receivables and payables Run the aged listings. Chase what is late, investigate credit balances and anything with a negative sign, and note accounts that are drifting toward uncollectible while the evidence is still fresh. This is where [receivables management](https://www.everstonecpa.com/blog/accounts-receivable-collection-small-business) actually happens. Not sure how this applies to you?

Post the recurring adjustments Amortisation for the month, the current portion of anything prepaid, accrued costs incurred but not yet billed to you, and any inventory movement. These are the entries that separate a book that shows profit from a book that shows cash movement, and doing them monthly means the year-end versions are a check rather than a discovery. Prepaids in particular have a habit of appearing only at year end. See [prepaid expenses at year end](https://www.everstonecpa.com/blog/prepaid-expenses-year-end-canada). ### 7. Clear the owner accounts Process the month’s reimbursements against receipts, record dividends declared, and make sure the [shareholder loan](https://www.everstonecpa.com/blog/shareholder-loans-canada-taking-money-out-of-corporation) balance is a number you recognize. Left to accumulate, it causes more year-end work than any other account. ### 8. Review, then lock Compare profit and loss with last month and the same month last year, and question anything that moved without a reason. Then close the period and set the lock date. File the reconciliation reports and aged listings with the records for the period. ## Why this makes year end straightforward The corporate year end is mostly verification. With twelve closed months, it means reviewing proven balances, applying tax adjustments and mapping to the GIFI codes on Schedules 100 and 125 of the T2, which is fast when the [chart of accounts](https://www.everstonecpa.com/blog/chart-of-accounts-small-business-canada) was built for it. Otherwise it starts with rebuilding the year from statements, with a question for you on every ambiguity. Closed months have a second payoff beyond the CRA: comparatives — this month against last month and against the same month last year. Comparatives make monthly figures useful for decisions, and they make a cash forecast possible, which matters most in a [seasonal business](https://www.everstonecpa.com/blog/managing-cash-flow-seasonal-business-canada). ## Making it stick Book a fixed working day each month and treat it as a deadline. Use the same checklist every time. Keep annual items, such as the inventory count and year-end tax review, on a separate list so the monthly routine stays short. If months have stacked up, close them in order, because each closed month gives the next a reliable opening balance. That is how [catch-up work](https://www.everstonecpa.com/behind-on-bookkeeping) is sequenced.

That silently breaks your comparatives, interim reporting and agreement with the [GST/HST returns](https://www.everstonecpa.com/gst-hst-filing-services) already filed. **How long should a monthly close take?** For a typical owner-managed corporation with a clean chart of accounts and reconciled feeds, it is a short exercise once it is a habit — the work is mostly reviewing rather than fixing. The first few take longer because they surface everything that was never resolved, which is the point of doing them. **Does closing monthly really make year end cheaper?** With twelve closed months, the year-end work is verifying proven balances, applying tax adjustments and mapping to the GIFI codes on the T2 schedules. Without them, it starts with reconstructing the year from statements, months later, with a question for every ambiguity. **What should I do about the shareholder loan each month?** Process reimbursements against receipts, record dividends declared, and confirm you recognize the shareholder loan balance. Left alone, it causes the most year-end work. **What if I am several months behind?** Close them in order, not starting with the current month. Each closed period gives the next its proven opening balance, so working forwards is faster and more reliable. That is how catch-up bookkeeping is structured. ## Want a close that actually happens every month?
