CRA-Ready Records: Can You Explain the Number and Find the Proof?

If the Canada Revenue Agency (CRA) asks for records, can you show where a number on your return came from? That matters more than a complicated folder system. Bank statements, invoices, entries in your books and filed returns each show different details. Keep them connected so someone else can follow the calculation.

“CRA-ready” is an organizing objective, not a certification or a promise that a claim will be accepted. Good retrieval cannot make an ineligible expense deductible. It can make the facts, calculations, and unresolved questions easier to review.

Build an evidence chain, not a document pile

For a sale, keep the invoice, any related credit notes, proof of payment and the entry showing when you recorded the income and how you handled the tax. For a purchase, keep the supplier document and details of its business purpose, any split between uses, and payment where applicable. A card charge alone may not show enough detail to support an input tax credit, which is a claim to recover eligible GST/HST on purchases.

• Connect source documents to transaction dates, amounts, accounts, and reporting periods.
• Preserve calculations for estimates, allocations, adjustments, and reconciliations.
• Keep contracts and correspondence that explain unusual terms or transactions.
• Retain the filed version of the return and the supporting working papers.
• Identify missing evidence explicitly rather than quietly substituting an unsupported number.

Make records easy to find even when staff leave. “In Maya's inbox” is not a reliable filing location. A useful file name helps, but also give each transaction a reference that connects the entry to its supporting document.

Retention is a decision, not an automatic deletion date

For GST/HST support, the general rule is to keep records for six years from the end of the last tax year to which they relate. That wording matters: it is not always six years from the invoice date, upload date, or date a file was closed internally. Other records and circumstances can require different treatment.

Retention review points rather than universal destruction permissions

Record or situation	Starting point	Before disposal
Ordinary GST/HST supporting records	Generally six years from the end of the last relevant tax year	Confirm the relevant year and whether an exception applies
Objection, appeal, unresolved review, or preservation notice	A continuing hold may extend retention	Resolve the hold under applicable instructions; do not rely on age alone
Late or unfiled returns	Special retention consequences can apply	Confirm the applicable period rather than using the normal calendar
Long-lived asset and ownership history	Records may remain relevant to later years or a disposition	Assess ongoing relevance and applicable longer-term requirements
Proposed early destruction	Written CRA permission may be needed	Obtain required permission before destroying records

Registered charities have their own books-and-records requirements and category-specific retention rules. A charity guidance page is not the legal basis for a general business disposal policy. Likewise, a general business minimum should not replace a charity's specific schedule.

Assign disposal approval to someone who can check tax, legal, contractual, and active-review holds together. A storage subscription ending or a cabinet becoming full is not a retention exception.

A fictional request at an upholstery shop

Imagine a small upholstery shop receives a request for support for selected GST/HST input tax credits from a four-month period. Three entries under review contain tax amounts of $312, $188, and $94, totalling $594. The request itself determines what must be supplied and when; this example does not describe an actual CRA selection procedure.

The shop's bookkeeper retrieves the three ledger references, supplier invoices, payment matches, and the return reconciliation. Two invoices are readily available. For the third, only a card slip exists. Instead of treating the slip as equivalent evidence, the team requests a duplicate supplier invoice and flags the gap for the reviewer.

The response index identifies each requested item, its supporting file, and any explanation. If an allocation was used, the calculation accompanies it. The team checks that the uploaded documents are readable and correspond to the correct period before sending them through the authorized channel.

Without that chain, searching by supplier name might find several similar invoices but still fail to explain which one supports the claimed amount. The practical benefit of organization is an answer that can be followed, not simply a faster pile of attachments.

Keep digital records usable beyond today's login

Records must remain accessible to CRA as required. Test whether historical documents, accounting detail, and relevant electronic data can still be retrieved after a software change. A backup that cannot be opened, a broken shared link, or a former employee's account is not a usable retrieval plan.

Keep originals and relevant electronic records. Do not assume a summary PDF replaces them all. Before discarding paper, check that scans are complete and readable and that the rules allow it. Plan how to export and open your records if you cancel a service, and assign someone to do it.

Where records are in another language, retain the originals and be prepared to provide an English or French translation as required. Protect confidential information during retrieval; give access through approved channels rather than forwarding an entire client archive unnecessarily.

Run a small retrieval drill before a real request

Choose one recent return and trace a sale, a purchase, and an adjustment back to their evidence. Record what was missing, who owns the correction, and whether the retention schedule reflects current holds. A short drill can reveal a broken link while the supplier and staff member are still reachable.

Bookwits can coordinate document requests, files, checklists and review tasks. It does not certify your records or decide whether CRA will accept your tax treatment. Keep the final supporting documents, unanswered questions and professional advice clearly identified. A task marked complete does not prove a tax claim is correct.
