Client document collection for accounting firms: a practical checklist

Give every request a clear next action

A useful document request tells the client what to provide, which period it relates to, where to send it, and what remains outstanding. For an accounting firm, the goal is a request the client can act on without another clarification email.

The checklist below is an operational starting point. Adapt it to the engagement and client. It is not an exhaustive tax filing checklist, and a requested document does not establish that an expense or credit is eligible.

Start with the engagement, not a universal upload list

Create separate request templates for personal tax, business tax, and bookkeeping. Ask the engagement owner to confirm which items apply before sending them. Avoid asking every client for every possible document.

Our suggested request fields are below. Include a way for clients to say an item does not apply or is unavailable, so a missing upload does not become an endless reminder.

• Document or information requested, written in plain language.
• Tax year, month, or other period covered.
• Reason the team needs it for this engagement.
• A clear submission location and requested response date.
• Status: requested, received, needs clarification, or reviewed.
• Team member responsible for the next follow-up.

Keep original evidence connected to the work

The CRA’s record-keeping guidance covers electronic business records as well as paper records. It also explains that using a third party for record keeping does not remove your responsibility to maintain adequate records.CRA: Keeping records

As a workflow recommendation, preserve a link between an extracted fact and the source record. Keep revised files distinguishable from earlier versions. A tidy summary should help someone find the evidence, rather than become the only surviving account of it.

For example, a request for “March bank statement for the operating account” is more actionable than “send banking.” When it arrives, record the period and account, then check whether the requested pages are present before marking collection complete.

Build retention into the process

CRA guidance generally calls for keeping records for six years from the end of the last tax year they relate to. Exceptions and longer requirements can apply, so a general six-year reminder should not become an automatic deletion rule.CRA: Keeping records

Revenu Québec similarly describes a general six-year period after the last year to which registers and supporting documents apply. Its guidance requires electronic records to remain accessible and readable, and notes longer retention for certain objections or court disputes.Revenu Québec: Keeping registers and supporting documents

Have the responsible advisor confirm the retention rule for the actual records and circumstances. Document who can delete records and how the team handles exceptions before relying on an automated cleanup process.

Follow up on the gap, not the whole file

Before sending a reminder, compare the request list with what has arrived. Name only the outstanding or unclear items. If a file was uploaded but cannot be used, explain the problem instead of treating it as absent.

An AI-assisted workflow could draft that targeted follow-up for review. A person should verify that the requested item is actually missing, that the wording fits the client, and that the chosen channel is appropriate. This is a proposed workflow, not a measured claim about response rates.

Keep receipt and approval distinct. “Document received” tells the client the upload arrived; “reviewed” means a person has completed the relevant check. Clear status language helps everyone understand the next action.
