A missing timesheet can become a costly problem long after the employee who completed it has moved on. The same is true of an unfiled TD1, a payroll adjustment with no explanation, or a T4 amount that cannot be traced back to a pay run. Payroll record retention is not simply an administrative task. It is the evidence behind the wages, deductions, remittances, and year-end slips your business reports.
For Canadian small-business owners, keeping complete payroll records protects the business during a CRA review, helps answer employee questions with confidence, and makes year-end reporting far less stressful. The goal is not to save every piece of paper indefinitely. It is to retain the right information, in a secure system, for the required period.
What payroll records should you keep?
A payroll file should allow someone to understand exactly how each employee’s pay was calculated and where the money went. If a number appears on a pay stub, remittance, T4, or T4A, you should be able to support it with underlying records.
For each employee, this generally includes their name, address, Social Insurance Number, date of hire, job title, rate of pay, and completed federal and provincial TD1 forms. Keep employment agreements and written records of changes to pay, benefits, vacation arrangements, or work status as well. These documents establish the terms behind the payroll calculation.
For every pay period, retain time records, salary or commission calculations, overtime details, vacation pay calculations, pay statements, and records of taxable benefits or allowances. For owner-managers, keep the records supporting any salary, bonus, director fee, or other payroll payment. A payment from the company account alone does not explain whether an amount was employment income, a shareholder advance, a dividend, or a reimbursement.
Your payroll records should also include documentation showing deductions for income tax, Canada Pension Plan contributions, and Employment Insurance premiums. Save payroll registers, remittance calculations, confirmation numbers, bank records, and notices or correspondence from the CRA. At year-end, retain copies of T4 and T4A slips and summaries, along with the working papers used to prepare them.
Where benefits are provided, keep the details used to determine whether they are taxable. This may include vehicle logs, group insurance invoices, cellphone policies, expense reimbursements, gift records, and records of employer-paid premiums. These items are often where payroll treatment becomes less obvious, so clear supporting documents matter.
How long should payroll records be retained?
The CRA generally requires businesses to keep records and supporting documents for six years from the end of the last tax year to which they relate. For example, records relating to a 2025 tax year would generally be kept until the end of 2031. This period applies broadly to records used to determine tax obligations, including payroll documentation.
Six years is a baseline, not an automatic disposal date. Do not destroy records if the CRA has asked you to keep them, if an objection or appeal is underway, or if a matter involving an employee remains unresolved. You may also need to consider provincial or territorial employment standards, workers’ compensation requirements, benefit-plan rules, and contractual obligations. These requirements can differ by location and record type.
For that reason, a practical policy is often to retain payroll files for at least six full years after the relevant tax year, then review whether there is a reason to keep them longer. Businesses with ongoing disputes, complex compensation plans, or frequent employee turnover may benefit from a longer retention schedule for selected employment records.
Why payroll record retention affects more than compliance
Good records are your first line of support if the CRA asks how you calculated a remittance or reported an employee benefit. Without them, a review can take longer, require more reconstruction work, and create unnecessary uncertainty. Accurate documentation helps your accountant respond based on facts rather than estimates.
Retention also protects the relationship with your employees. Questions about overtime, vacation balances, tax deductions, or a prior year’s T4 can arise months later. When payroll information is organized, you can give a timely, consistent answer instead of searching through emails and old bank statements.
There is also a business-management benefit. Payroll records show the real cost of employing people, including employer CPP and EI contributions, benefits, and vacation pay. When these details are captured properly, owners can make better decisions about hiring, pricing, cash flow, and compensation.
Create a payroll retention system you can actually maintain
The best system is one your business will use every pay period. A sophisticated platform is not helpful if timesheets are still being approved by text message and payroll changes are kept only in someone’s inbox. Start by choosing one central, access-controlled location for payroll records, whether that is a payroll platform, secure cloud storage, or both.
Organize files by tax year, then by employee and pay period. Use consistent names that make documents easy to locate, such as “2025-04-15 Payroll Register” or “Employee Name – 2025 TD1.” Keep a separate folder for CRA remittances, year-end slips, and payroll correspondence. The person reviewing a file should not have to guess which version is final.
A simple recurring process is more valuable than an annual cleanup. After each payroll run, save the payroll register, approved time record, pay statement, remittance calculation, and proof of payment. When a pay rate changes or a benefit is added, save the approval and the effective date at the same time. This takes minutes when done regularly and hours when reconstructed later.
Because payroll files contain highly sensitive personal information, limit access to people who genuinely need it. Use strong passwords, multi-factor authentication where available, and secure sharing methods. Avoid sending Social Insurance Numbers, TD1 forms, and payroll reports through unsecured personal email accounts. Paper files should be stored in a locked location, with a clear process for who may access them.
Common recordkeeping gaps to address now
Many payroll issues begin with a small process gap rather than an incorrect intention. An owner may pay a casual worker before receiving a completed TD1, reimburse an expense without retaining receipts, or change an employee’s salary without documenting the effective date. Each choice makes later reporting more difficult.
Watch for these common gaps:
- Employee files that do not include current TD1 forms, written pay terms, or records of changes to employment status.
- Time and overtime records that are incomplete, approved late, or kept only in informal messages.
- Payroll remittances that can be seen in the bank account but are not matched to a payroll calculation or CRA confirmation.
- Taxable benefits, bonuses, advances, and reimbursements that are not clearly categorized and supported.
- Year-end T4 records that do not reconcile to payroll registers, general ledger wages, and remittances.
A bank withdrawal confirms that money left the account. It does not prove the correct payroll treatment. Reconciliation between payroll reports, bank activity, remittances, and year-end slips is what makes the record reliable.
Payroll record retention when you use software or a provider
Payroll software can produce useful reports, but the business remains responsible for its records. Before changing providers or cancelling a subscription, download payroll registers, employee histories, remittance reports, year-end slips, and relevant audit reports. Confirm that the exported files are readable and stored securely.
The same principle applies when an outside bookkeeper or accountant manages payroll. A qualified provider can improve accuracy and keep the process on schedule, but you should know where your records are kept and how to access them. Clear roles help: the employer supplies approved hours and payroll changes, while the payroll professional calculates, files, reconciles, and flags issues requiring a decision.
At RheaM Accounting, we encourage clients to treat payroll documentation as part of their financial foundation, not a pile of forms to address at year-end. A short review of your current payroll files can reveal what is missing before a CRA question, employee concern, or deadline forces the issue.
Set aside time after your next payroll run to check one employee file from start to finish. If you can trace their hours, pay, deductions, remittance, and year-end reporting without searching through multiple systems, you are building the kind of recordkeeping that supports your business when it matters most.
