Business Records Retention in Canada: How Long to Keep Records
Records retention in Canada: how long to keep business records, CRA's six-year rule, electronic records, and a simple retention schedule for sole proprietors.
In Canada, records retention for a sole proprietorship generally means keeping your business records for at least six years from the end of the last tax year they relate to. That requirement comes from the federal Income Tax Act and applies to the files behind your T2125, your GST/HST returns, and any payroll you run. Most sole proprietors keep records longer than the minimum, because certain events restart the clock.
How long do you need to keep business records in Canada?
The general rule is six years from the end of the last tax year to which the records relate. Because a sole proprietor's income tax year is the calendar year, records supporting your return would ordinarily be kept for at least six years. A similar six-year expectation applies to GST/HST records and to payroll records. Retention rules can change, so confirm the current period on the CRA website before you shred anything.
Different record types are tied to different starting points:
| Record type | Typical retention period |
|---|---|
| Income tax records (receipts, invoices, bank statements, T2125 backup) | Six years from the end of the last tax year they relate to |
| GST/HST records and returns | Six years from the end of the year to which they relate |
| Payroll and employee records | Generally six years federally; provincial employment standards may set different periods |
| Records for a capital asset you sold | Six years from the end of the tax year in which you disposed of it |
| Records tied to an objection or appeal | Until the matter is settled, plus the normal period |
What counts as a business record?
CRA's definition of a record is broad. It covers anything that supports the income you reported and the expenses you deducted, whether it lives on paper or on a hard drive.
- Sales invoices and receipts you issued
- Purchase receipts, supplier invoices, and bank or credit card statements
- Contracts, leases, and loan or financing documents
- GST/HST returns, working papers, and input tax credit calculations
- Payroll records, T4 and T4A slips and summaries, and source deduction remittances
- Mileage logs, inventory counts, and capital asset purchase and disposal records
- Digital files, spreadsheets, and emails that document a transaction
Your invoicing habits matter here. If your invoices don't show the details CRA expects — including your Business Number where GST/HST applies — your records are weaker. See GST/HST invoicing requirements in Canada and how to invoice as a sole proprietor for the fields to include.
Can you keep records electronically?
Yes. CRA allows electronic records, and most sole proprietors now work paperless. The conditions are practical rather than technical: records must be kept in an accessible and readable format, retained for the full period, and produced in a readable form if CRA asks to see them. Back up your files, restrict access where records contain personal information, and make sure you can still open older formats years later.
If you store data with a cloud provider, confirm you can retrieve and provide the records on request. Keeping a simple folder structure by tax year, with separate folders for GST/HST and payroll, saves hours during a review. Good bookkeeping and retention go together — see bookkeeping for sole proprietors for a workable routine, or compare tools in accounting software for Canadian small business.
When does the retention clock restart?
Several situations extend the six-year rule:
- Late filing. If you file a return after the deadline, keep the supporting records for six years from the date you filed, not the original due date.
- Objections and appeals. Keep everything connected to a notice of objection or appeal until the matter is resolved, then for the normal period.
- Disposing of property. Records for a capital asset — including its purchase cost — must be kept for six years after the year you sell or dispose of it.
- Non-tax obligations. Provincial employment standards, workers' compensation, and immigration rules can require different or longer retention for employment records.
If you're winding down, plan the retention side too; closing the business does not erase your record-keeping obligations. Our guide to closing a sole proprietorship in Canada covers what to keep after you stop operating.
Practical storage and organization tips
A retention policy only works if you can find the document later. A few habits make this easy:
- Name scans with the date, vendor, and amount so they sort chronologically.
- Keep tax-year folders for income tax, GST/HST, and payroll separately.
- Back up to two locations — for example, a cloud drive and an external drive.
- Review and securely destroy records only once their retention period has genuinely expired.
When you do dispose of old records, shred or securely delete anything containing personal or client information, since privacy obligations continue independently of tax retention rules.
What happens if you can't produce records?
If CRA reviews your return and you can't support a deduction, the expense can be disallowed, which increases your taxable income and the tax owing. Failing to keep records as required can also attract penalties under federal tax legislation, and the amount depends on the circumstances. Because the burden of proof sits with you, a modest amount of organised record keeping is far cheaper than reconstructing a year from bank statements.

Frequently asked questions
How long do I need to keep business records in Canada?
Generally six years from the end of the last tax year the records relate to. For a sole proprietor on a calendar tax year, records for 2026 would normally be kept until at least the end of 2032. GST/HST and payroll records follow a similar six-year expectation. Certain events — late filing, an objection, or disposing of a capital asset — extend the period, so confirm the current rule on the CRA website.
Can I keep my business records electronically for CRA?
Yes. CRA accepts electronic records provided they are kept in an accessible, readable format, retained for the full period, and can be produced in a readable form if requested. Many sole proprietors scan receipts and store them in the cloud. Back up your files, keep them secure, and make sure you can open older file formats years later in case of a review.
Do I need to keep records for a year I had no income?
Yes. Even in a year with no revenue, you may have expenses, GST/HST filings, or a loss to carry forward, and all of those need supporting records. The retention clock runs from the end of the tax year regardless of whether you earned income. Keeping records for slow or dormant years protects you if CRA later reviews that return.
What happens if I don't keep proper business records?
If you cannot support a deduction, CRA can disallow the expense, which increases your taxable income and the tax you owe. Failure to keep records as required may also result in penalties under federal tax legislation, with amounts depending on the circumstances. The legal obligation to keep records rests with you, so organised files are the simplest protection.
