The General Rule: Six Years

In Canada, the general rule is that you must keep your tax records for six years from the end of the tax year they relate to. For example, if you are filing your 2024 tax return, you must keep all supporting records until at least December 31, 2030.

This is because the CRA normally has three years from the date of assessment to reassess your return, but keeping records for six years provides an extra safety margin and meets the legal requirement.

For proper compliance, many Canadians use tax return filing services.

What Records Do You Need to Keep?

The CRA requires you to keep any document that supports the income, deductions, and credits you claimed on your return. This includes:

• T4 slips, T5 slips, T3 slips, and other income slips
• RRSP and TFSA contribution receipts
• Receipts for medical expenses, charitable donations, and tuition
• Notices of Assessment from the CRA
• A copy of your filed tax return for each year
• Rental income and expense records
• Investment purchase and sale records
• Employment expense receipts if you claimed them
• Business income and expense records if self-employed

Working with tax and accounting services can make this process easier.

Records for Self-Employed and Business Owners

If you operate a business, the CRA requires you to keep your business records for six years from the end of the last tax year they relate to. This includes:

• Sales records and invoices issued to customers
• Expense receipts and purchase invoices
• Bank and credit card statements
• Payroll records if you have employees
• GST/HST records and returns
• Contracts, leases, and business agreements

If you close a business, you must still keep the records for six years from the end of the tax year in which the business closed.

A small business accountant can help organize these records efficiently.

Capital Property Records: Keep Longer

For capital property such as real estate, stocks, or other investments, the rules are different. You must keep records for as long as you own the property, plus six years after the year you sell it.

This means if you bought a rental property in 2005 and sold it in 2025, you would need to keep all related records until at least December 31, 2031.

This includes the original purchase price, improvement costs, and all rental income and expense records throughout the ownership period.

A professional tax accountant near me can help calculate adjusted cost base correctly.

Electronic Records Are Acceptable

The CRA accepts electronic records, as long as they are legible and accessible. If you scan your paper receipts and store them digitally, you can discard the paper copies once the scanned versions are verified to be complete and clear.

Digital record-keeping tools and accounting software are fully acceptable.

Many tax accountants recommend maintaining cloud backups.

What If You Filed Late or There Was a Dispute?

The six-year retention period starts from the end of the tax year, regardless of whether you filed your return on time or late.

However, the CRA can reassess a return beyond the normal period if there was misrepresentation, fraud, or if you waived the limitation period.

In those cases, there is no time limit on how far back the CRA can go.

For disputes, an accountant for taxes may help you manage CRA reviews.
