Most small business owners don't find out their books are behind until tax season, a loan application, or a CRA letter forces the question. This checklist is meant to catch that earlier — twelve concrete things to check, grouped into the four places bookkeeping problems most often start.

How to use it: go through each section honestly. If you're missing more than two or three items in any one section, that's usually the first place to focus — not the whole system at once.

Reconciliation

  • Every bank and credit card account is reconciled against its statement, with no month left open.
  • Reconciliation happens monthly, not in a batch at tax time — gaps of 3+ months are where errors hide.
  • Uncleared or stale transactions (voided cheques, old deposits) are investigated, not just left sitting on the books.

Categorization & records

  • Transactions are categorized to a proper chart of accounts, not dumped into a generic "miscellaneous" bucket.
  • Personal and business expenses are kept fully separate — no mixed-use accounts or cards.
  • Receipts for anything you’d want to defend in a CRA review are attached or filed, not just assumed remembered.

HST/GST & payroll

  • You know your actual HST/GST filing frequency (monthly, quarterly, or annual) and its next due date.
  • Input tax credits are being tracked and claimed — not left on the table because receipts weren’t categorized correctly.
  • If you run payroll: remittances, T4s, and ROEs are filed on schedule, not caught up after the fact.

Reporting & review

  • You get a profit & loss and balance sheet monthly — not just once a year for your accountant.
  • Your reports are current enough (within 30 days) to make a real decision from, not three months stale.
  • Someone other than the business owner reviews the books at least once a month, catching errors a single set of eyes tends to miss.

That's not unusual — it's the normal state for a business running its own books alongside everything else involved in running the business. The fix is rarely "try harder," it's usually a system: monthly reconciliation on a schedule, a proper chart of accounts, and a second set of eyes on the numbers.
