Rauf Hameed on How Long You Actually Need to Keep Business Records for the CRA

Nobody gets excited about record retention. That's just the truth. Every client we talk to at Rauf Hameed wants to talk about deductions and tax savings and none of them want to talk about how long they should be holding onto a stack of receipts sitting in a shoebox in their garage. But this is one of those boring topics that turns into a real problem the moment the CRA sends a letter and someone realizes they shredded exactly the documents they needed three years too early.

The Basic Rule Most People Get Wrong

The general rule is six years from the end of the tax year the records relate to. Most business owners think it's the year they filed the return which is close but not quite right and that small gap has actually burned a few of our clients who did the math slightly off and tossed a box of invoices a full year before they legally could. So if your 2021 fiscal year ended in December that year your records need to stick around until the end of 2027 not 2026.

This applies to everything you'd expect. Invoices bank statements payroll records contracts and any supporting documentation for expenses you claimed. It also applies to things people forget about like mileage logs and home office calculations which sound minor until an auditor asks for them specifically and you're stuck trying to reconstruct a year old commute pattern from memory.

What Happens If You Toss Records Early

Here's where it gets uncomfortable. If the CRA reviews a return and you can't produce supporting documentation they don't just take your word for the deduction. They disallow it. We had a client last year who had claimed a fairly large vehicle expense and when the review letter came in he genuinely could not locate the original logbook because it had gotten mixed into a pile of stuff during an office move. The claim got reduced and he owed money back with interest attached. It wasn't fraud. It wasn't even carelessness in the way people usually picture it. It was just a document that physically disappeared at the wrong moment.

A Small Tangent About My Own Filing Habits

I'll admit something here that has nothing to do with tax law. I still keep every single warranty card for every appliance I've ever bought in a drawer that doesn't even close properly anymore and half of those warranties expired years ago. My wife asks me constantly why I don't just throw them out and I genuinely don't have a good answer. There's something about paperwork that makes people either obsessively organized or completely chaotic and almost nobody sits comfortably in the middle. Business owners are the same way with their books and it usually takes one bad CRA letter to snap someone from chaotic into obsessive practically overnight.

Digital Records Are Fine But Backups Matter More Than People Think

The CRA accepts digital records as long as they're complete and accessible in a readable format for the full retention period. That's good news because almost nobody is printing paper invoices anymore. But we still see business owners store everything on a single laptop with zero backup and that laptop eventually crashes or gets stolen and suddenly six years of documentation is just gone. A cloud backup or a second physical drive costs almost nothing compared to the mess of trying to reconstruct records after a review notice arrives.

When You Can Legally Destroy Records Early

There's one exception worth knowing. If you want to destroy records before the six year window ends you technically need written permission from the CRA which almost nobody applies for and honestly most accountants including us would tell you it's not worth the hassle for the small amount of storage space you'd save. Keep the records. Six years passes faster than people expect anyway.

If your business has ever been incorporated dissolved or sold there are separate rules around final year retention and those get complicated fast which is exactly the kind of situation where a quick call to someone at Rauf Hameed saves a business owner from guessing wrong on something that actually matters.

Frequently Asked Questions

Does the six year record retention rule apply to personal tax returns as well as business filings?
Yes, it applies broadly across both personal income tax records and business bookkeeping documentation though business owners tend to accumulate far more paperwork that falls under the rule.

What counts as acceptable supporting documentation during a CRA audit?
Original invoices receipts bank statements payroll records and any document that directly supports a claimed deduction or reported income figure. Vague summaries or estimates generally don't hold up.

Can a small business rely entirely on accounting software for record keeping instead of physical files?
Yes as long as the software stores complete readable records for the full retention period and there's a reliable backup in place in case of a system failure.

Conclusion

Record retention is not glamorous and it's never going to be the exciting part of running a business. But it's also one of the cheapest forms of protection a business owner has against a CRA review turning into a genuinely expensive problem. SIX YEARS feels like a long time until you're the one standing in front of a review letter with nothing to back up a claim you made honestly. Keep the documents organized keep a backup and treat this the same way you'd treat insurance. You hope you never need it and you're relieved every single time it turns out you did.
