How Long to Keep Tax Records in Canada (2026 Guide)

You filed your taxes — great. Now you are staring at a pile of receipts, slips, and old returns wondering: do I actually need to keep all of this?

The short answer is yes — for at least six years. But there are important exceptions that could cost you money if you ignore them.

This guide explains exactly how long to keep your Canadian tax records in plain language, what documents to hold onto, and when you can safely shred the rest.

Quick Answer: Keep your tax records for 6 years from the end of the tax year they relate to. For your 2026 tax return, that means keeping everything until at least December 31, 2031. Some records — like property documents — need to be kept much longer.

The Basic Rule: 6 Years

The Canada Revenue Agency (CRA) requires all taxpayers — individuals and businesses — to keep their tax records and supporting documents for six years from the end of the last tax year they relate to.

This is not a suggestion. It is a legal requirement under the federal Income Tax Act. If the CRA audits you and you cannot produce your records, they can deny your deductions, reverse your credits, and charge penalties of up to $25,000.

When does the 6-year clock start?

This is where most Canadians get confused. The clock does not start when you file your return or when you receive your Notice of Assessment. It starts at the end of the tax year the records relate to.

For individuals, the tax year is the calendar year (January 1 to December 31).

Practical tip: Keep records for 7 years to give yourself a comfortable buffer. It costs almost nothing to store a folder of old files, and it protects you completely.

3 Situations Where You Must Keep Records Longer

The 6-year rule has exceptions. In these situations, you need to hold on to your records longer — sometimes much longer.

1. If You Filed Your Return Late

If you filed a tax return after its due date, the 6-year clock starts from the date you actually filed, not from the end of the tax year.

Example: You filed your 2021 tax return in 2024 (late). Your 2021 records cannot be destroyed until 2030 — not 2027.

This catches a lot of Canadians off guard. If you have ever filed late even once, double-check your timeline for that year.

2. If You Have Filed an Objection or Appeal

If you have formally disputed a CRA assessment or are in the middle of an appeal, you must keep all related records until the latest of these three dates:

• When the objection or appeal is fully resolved
• When the deadline for any further appeal has passed
• When the normal 6-year period ends

Tax disputes can take years to resolve. Do not destroy anything while a case is open.

3. If You Own Property (Real Estate, Rental, Business Assets)

This is the most important exception for homeowners and landlords. If you own a property, you need to keep records related to that property from the day you buy it until 6 years after the year you sell it.

Example: You bought a rental property in 2015 and renovated the basement in 2018 for $30,000. You sell the property in 2026. You need to keep those 2018 renovation receipts until 2032 — because they affect your adjusted cost base and your capital gain when you sell.

If you cannot prove your purchase price and renovation costs, the CRA may calculate a much higher capital gain than you actually had — and you pay more tax than you owe.

Rule of thumb: Keep property records indefinitely while you own the property, then for 6 years after the year you sell.

What Documents Do You Actually Need to Keep?

For Personal Tax Filers

• A copy of your filed tax return (T1 General)
• Your Notice of Assessment (NOA) for each year
• T4 slips — employment income from your employer
• T5 slips — investment income (interest, dividends)
• T3 slips — trust income
• RRSP contribution receipts
• Medical expense receipts
• Charitable donation receipts
• Childcare expense receipts
• Tuition receipts (T2202)
• Moving expense receipts (if you claimed them)
• Bank statements as backup for any deduction or credit you claimed

For Self-Employed Canadians and Business Owners

Business owners have more extensive obligations on top of everything above:

• General ledger and bookkeeping records
• All sales invoices issued to clients
• All purchase receipts for business expenses
• Bank and credit card statements
• GST/HST returns and remittance records
• Payroll records including T4s issued, CPP and EI deductions
• Vehicle logbooks if you claimed vehicle expenses
• Contracts and agreements
• Business asset purchase records

Vehicle logbook tip: The CRA frequently challenges vehicle expense claims. Your logbook must record the date, destination, purpose, and kilometres for every business trip — all year long. Recreating it at tax time from memory is both difficult and a red flag for auditors.

Can You Keep Digital Copies Instead of Paper?

Yes — the CRA fully accepts electronic records. You do not need to keep boxes of paper. But there are rules your digital records must meet:

• Documents must be clear and legible — a blurry photo does not count
• Each record must show the date, vendor or payer name, amount, and description
• You must be able to produce them on request in a format the CRA can read
• Keep backup copies stored in a second location (second cloud account, external hard drive kept at home)

One Thing Most Canadians Do Not Know About Cloud Storage

If your digital records are stored on servers located outside Canada, the CRA does not consider them to be kept in Canada — even if you can access them from your living room in Hamilton.

Many popular cloud storage services (Google Drive, Dropbox, iCloud) may use American servers. To store records abroad legally, you need written permission from the CRA.

Safer options: Microsoft 365 with Canadian data residency selected, AWS Canada (Montreal region), or physical backup drives kept at your Canadian home or office.

What Happens If You Destroy Records Too Early?

Destroying records before the 6-year window closes — without CRA permission — is a serious mistake:

• The CRA can deny any deductions you claimed if you cannot prove them during an audit
• Penalties of up to $25,000 under the Income Tax Act
• In cases of deliberate destruction to evade taxes, criminal prosecution is possible

If you genuinely need to destroy records early — for storage or privacy reasons — apply to the CRA in writing using Form T137 (Request for Destruction of Records). The CRA reviews your situation and responds with written permission if approved.

What You Can Safely Clear Out in 2026

As of 2026, based on the 6-year rule, most Canadians can safely destroy records from 2019 and earlier — as long as:

1. You filed that year's return on time (if you filed late, the clock started from your filing date, not the year end)
2. There are no open disputes, objections, or audits from that year
3. None of those records relate to property you still own today

When in doubt, keep it. A shredder is permanent.

Frequently Asked Questions

How long do I need to keep tax records in Canada?

The CRA requires you to keep tax records and supporting documents for 6 years from the end of the last tax year they relate to. For your 2026 tax return, that means keeping everything until at least December 31, 2031.

Does the 6-year clock start when I file my return or at the end of the tax year?

It starts at the end of the tax year — December 31 for individuals. Not when you file and not when you receive your Notice of Assessment. This trips up a lot of Canadians who assume the clock starts on April 30 when they submit their return.

I filed my taxes late one year. Does that change anything?

Yes — if you filed a return late, the 6-year clock starts from the date you actually filed, not the end of the tax year. For example, if your 2021 return was filed in 2024, you must keep those records until 2030, not 2027.

Can I keep digital copies instead of paper records?

Yes. The CRA accepts electronic records as long as they are clear, complete, and readable. Scanned receipts, digital invoices, and electronic statements all qualify. Make sure to keep backup copies and confirm your cloud storage uses Canadian servers.

How long do I need to keep records for my house?

Keep all records related to a property — purchase price, legal fees, renovation receipts — from the day you buy it until 6 years after the year you sell it. These records affect your adjusted cost base and your capital gains tax when you sell.

Can the CRA go back more than 6 years?

In standard situations, no. But if there is suspected fraud or gross negligence, the CRA can go back further. The normal reassessment window is 3 years from your original Notice of Assessment. The 6-year record-keeping rule is your protection for the window beyond that.

What documents should I keep forever?

Keep your filed tax returns (T1) and Notices of Assessment indefinitely if you can. They are compact, easy to store digitally, and come in handy for mortgage applications, immigration paperwork, legal matters, and benefit calculations well beyond the standard 6-year window.

What happens if I throw away records too early?

If you are audited and cannot produce your records, the CRA can deny your deductions and assess additional taxes plus interest. Intentional early destruction can also trigger penalties up to $25,000. If you need to destroy records early, apply using Form T137 to get CRA permission first.

Do I keep GST/HST records for the same 6 years?

Yes. The same 6-year rule applies to GST/HST records. The clock starts after the last year those records are needed for reporting. If you have unfiled GST/HST returns from more than 6 years ago, you are still required to file them and keep the related records.

I am self-employed. What records do I specifically need to keep?

Self-employed Canadians must keep all personal tax documents plus: business invoices and receipts, bank statements, GST/HST records, payroll records if you have employees or contractors, vehicle logbooks if you claim vehicle expenses, and business asset purchase records. All for 6 years from the end of the tax year they relate to.
