Canadian Payroll Year-End Checklist: T4 and T4A Workflow

Payroll year-end is not finished when someone clicks “submit.” The right returns must be prepared from reconciled records, authorized, filed through the appropriate process, distributed securely and checked for acceptance. Payment and remittance obligations have their own rules and do not disappear because a return was filed.

This checklist helps organize the work. It does not calculate payroll or decide everything you must report. Check the Canada Revenue Agency (CRA) guidance for the tax year and your situation, plus the provincial rules that apply. Bookwits is not a payroll calculator or a CRA filing tool.

1. Confirm the employer, tax year and responsibilities

Start with the correct legal entity, payroll accounts, tax year, service providers and people responsible. Calendar-year information reporting and the company’s fiscal year-end are not automatically the same timeline. Do not copy last year’s assignments without checking changes.

Check which returns and slips you need. A slip reports amounts for a recipient; the return is the information filed with the tax authority. T4 and T4A slips serve different purposes and cannot simply replace each other. Paying a contractor does not settle every T4A question. Ask a qualified person to check the worker’s status, payment type and current official rules.

Clarify who prepares records, resolves discrepancies, approves the final return, submits, checks acceptance and distributes recipient copies. Where another provider does a step, identify what evidence the employer receives and who follows up if it is missing.

2. Reconcile the payroll records before preparing slips

Gather the payroll register, relevant accounting balances, remittance records, account information and supporting records for adjustments. Reconcile the categories that actually apply to the employer, including the relevant tax, pension and insurance amounts. Investigate differences rather than assuming a service provider’s total must be correct.

• Check employee changes, missing periods and final or off-cycle runs.
• Review benefits, adjustments and other reportable amounts using the appropriate guidance.
• Check corrections made outside the usual payroll process.
• Confirm that payments and remittances are recorded in the right periods and accounts.

Keep an exception list with an owner, evidence needed and resolution. A rounding explanation should be supported by the actual calculation; “probably rounding” is not a universal reason to ignore a discrepancy.

3. Build the actual filing and distribution calendar

CRA guidance generally places the standard T4/T4A annual information-return filing deadline on the last day of February following the relevant calendar year. Special situations can have different rules. If the applicable deadline falls on a Saturday, Sunday or CRA-recognized public holiday, check the CRA’s next-business-day rule.

Verify the precise date for the return, tax year and situation instead of hard-coding February 28 into every checklist. Separately confirm recipient-copy requirements, remittance dates, applicable electronic-filing requirements and any other authority’s obligations.

Separate deliverables with separate evidence

Deliverable	Calendar check	Completion evidence
Reconciled records	Internal review cutoff	Approved reconciliation and resolved exceptions
Information return	Actual return/year/situation	Submission and acceptance status
Recipient copies	Applicable distribution rule	Authorized secure distribution record
Payments/remittances	Applicable remitter obligations	Verified payment and account records

Set an earlier internal review date that allows time for missing information and rejection recovery. An internal target is not a replacement for the legal deadline.

4. Review the final data and protect personal information

Check the employer details, required recipient information, amounts, classifications and return totals using the current instructions. Have the authorized reviewer confirm the actual final version, not an earlier draft that has since changed.

Payroll files can contain very sensitive personal information. Collect only what you need. Use approved access and secure ways to handle and send files. Check the actual recipient before sending. Keep social insurance numbers (SINs) out of ordinary task titles and comments visible to a wide group.

If a name, identifier or classification is uncertain, resolve it through the appropriate process. Do not invent missing information to get past a validation screen. A technically accepted file is not proof that its underlying facts are correct.

5. Distinguish submission, acceptance and correction

Retain the submission evidence and check the returned status or confirmation through the applicable official/provider process. A click, a success message in another system or a saved PDF is not automatically evidence that the required return was accepted.

If the result is uncertain, check status before sending the same return again. Do not treat duplicate submission as a harmless retry. CRA guidance cautions against sending another electronic return unless the original was rejected; use the proper amendment process when correcting accepted information.

Keep filing, recipient distribution, remittance reconciliation and later amendments visible as separate steps. When a provider reports an error, assign the recovery, preserve useful evidence and check the actual outcome before closing the item.

6. Close with a retrievable handover record

Keep a short completion record. Include the business, tax year, returns required, approved comparison of records, approval date and proof of filing, acceptance and distribution. Include the check of remittances (amounts sent to the tax authority) and anything unresolved. Name who will handle questions or corrections after year-end work ends.

Bookwits’ assigned and recurring tasks can coordinate those responsibilities, and documents can organize appropriate evidence subject to your access and privacy rules. The actual payroll calculation, submission and acceptance check remain in the authorized payroll and government/provider processes.

Before copying the checklist into next year, review changed people, services, requirements and recurring exceptions. The goal is a supported completion trail, not simply reusing last year’s dates or marking every client green at once.
