Most CRA document requests are informal — a letter asking you to send in a receipt or explain a transaction. A Requirement for Information is different. It's a formal legal demand issued under the Income Tax Act, and unlike an informal request, non-compliance carries real legal consequences of its own, separate from whatever the underlying audit finds.

If you've received a letter labelled as a Requirement (sometimes called an RFI), it's worth understanding exactly what makes it different, and why ignoring it is far riskier than ignoring an ordinary audit letter.

What Makes a Requirement Different From a Regular Request

An ordinary audit or review letter is a request — the CRA is asking, and while non-response has consequences for your audit (denied claims, an unfavourable reassessment), it isn't itself an offence. A Requirement for Information is a formal demand backed by statutory authority under the Income Tax Act. The CRA can use this power to compel a taxpayer — or in some cases a third party, such as a bank — to provide specific documents or information within a stated time.

Key differences:

Why the CRA Uses This Tool

The CRA typically reaches for a formal Requirement when:

Receiving a formal Requirement, rather than an informal letter, is generally a signal that the audit has moved into a more serious phase and warrants a correspondingly serious response.

What to Do If You Receive One

  1. Read it carefully and note the deadline. Formal Requirements specify what's demanded and by when — treat that deadline as firm, not aspirational.
  2. Confirm what's actually being asked for. Requirements can be broad; understand precisely what documents or information fall within its scope before responding.
  3. Get legal advice before responding, especially if:
  1. Don't simply refuse without a documented, defensible reason. Unlike an informal request, walking away from a valid Requirement is not a neutral choice — it can trigger its own enforcement consequences.
  2. Respond completely, not selectively. Partial compliance can be treated the same as non-compliance if it doesn't satisfy what was actually demanded.

What a Requirement Cannot Reach

Not everything is fair game, even under a formal Requirement. Communications between you and your lawyer made for the purpose of seeking or giving legal advice are generally protected by solicitor-client privilege, and privileged documents can be withheld — though the process for asserting privilege against a CRA demand has its own procedural steps, and getting it wrong can waive the very protection you're trying to claim. If you believe privilege applies to some of what's been demanded, that's a strong reason to get legal advice before responding rather than after.

Third-Party Requirements: When the CRA Asks Someone Else About You

A Requirement doesn't only go to the taxpayer under audit. The CRA can direct one at a bank, business associate, or other third party who holds records relevant to your tax affairs. If you learn that a Requirement has been sent to your bank or a business contact regarding your own tax matters, that's a signal the audit has broadened, and it's a good time to involve a lawyer if you haven't already.

Frequently asked questions

Is a Requirement for Information the same as a subpoena?

Not exactly. A Requirement is an administrative demand issued directly by the CRA under the Income Tax Act, without needing to first go before a court, whereas a subpoena is a court-issued order tied to a proceeding. Both are legally compulsory, but a Requirement is a CRA-specific tool used earlier in the process, typically during an audit.

Can I negotiate the deadline or scope of a Requirement?

It's often worth contacting the CRA (or having a lawyer do so) to clarify scope or request a reasonable extension, particularly where the volume of records is genuinely large. Whether an extension is granted is within the CRA's discretion, so don't assume more time until it's confirmed.

What happens if I simply can't produce what's demanded because the records don't exist?

Explain this clearly and provide whatever secondary evidence you can. Non-existence of records is different from refusal to comply, but you'll still need to be able to substantiate that the records genuinely don't exist rather than that you're withholding them.

Should I always get a lawyer before responding to a Requirement?

Given that a Requirement carries its own compliance consequences and can intersect with privilege issues, it's generally worth at least a brief legal consultation before responding — especially if the request is broad, involves a third party, or touches on sensitive information.
