How to Prepare Your Books for Corporate Year End
A step-by-step year-end bookkeeping checklist for small incorporated businesses preparing for their corporate tax return.

The short answer: to get ready for corporate year end, reconcile every bank, credit card and loan account to the last day of the fiscal year, review who owes you and whom you owe, reconcile payroll and GST/HST, document large purchases and owner transactions, and gather everything in one place before the tax work starts.
Who this applies to
Small, owner-managed corporations in Canada. A corporation's tax year is its fiscal period, and the CRA requires the corporation income tax return (T2) to be filed within six months of the end of each tax year. Payment of any balance owing is generally due earlier than the filing deadline, so confirm your dates on the CRA's filing page.
The year-end checklist
- Reconcile bank and credit card accountsEvery account should match its statement to the last day of the fiscal year, with no unexplained items.
- Review accounts receivableConfirm which invoices are still owed to you, and identify any that will not be collected.
- Review accounts payableList bills that relate to this year but were not yet paid at year end.
- Reconcile loans and financingMatch loan balances to lender statements and separate interest from principal.
- Reconcile payrollMake sure payroll in the books agrees with payroll records and remittances for the year.
- Reconcile GST/HSTIf registered, confirm that amounts collected and paid in the books agree with what was filed.
- Document large purchasesEquipment, vehicles, computers and renovations are usually treated differently from everyday expenses. Keep the invoices.
- Count inventoryIf you hold inventory, count it as close to year end as possible.
- Record owner transactionsMoney the owner put in or took out, and expenses paid personally for the business, all need to be recorded and explained.
- Gather it in one placeStatements, the notes above, and last year's financial statements and return.
Common problems we see
- Personal and business spending mixed on the same card
- Deposits recorded as sales when they were loans, transfers or owner money
- Missing statements for an account that was opened or closed during the year
- Receipts for large purchases that cannot be found
All of these are much easier to fix monthly than at year end. That is why corporate tax preparation and monthly bookkeeping work best together.
