GST/HST Return Checklist: Records, Review and Proof of Filing

A goods and services tax (GST) or harmonized sales tax (HST) return needs a clear plan. Answer five questions: which account and period are involved, what records are needed, who prepares and checks the work, who files the return and how you confirm filing and payment. One date in a spreadsheet cannot answer all five.

This guide helps organize the work. It does not give tax advice or show how to calculate a return. GST/HST rules and deadlines depend on the situation. Check current Canada Revenue Agency (CRA) guidance and the client’s account. Check provincial obligations separately where needed, including those in Québec.

1. Verify the reporting period instead of assuming it

Before creating a recurring task, confirm the legal entity, GST/HST account, reporting period and the person responsible for filing. Use an appropriate identifier in internal records; avoid putting full sensitive account details into broadly visible task titles.

Verify the filing deadline and any payment deadline separately. Do not assume that every client is quarterly or that filing and payment always share the same date. The CRA’s reporting-requirements guidance is the authoritative starting point; a workflow template does not determine a client’s obligations.

2. Request the records required for this return

Start from the agreed work and the accounting system rather than requesting every financial document in the client’s history. Identify missing sales and purchase support, relevant account reports, adjustments and explanations needed by the preparer. The exact list depends on the file and professional judgment.

• State the entity and exact reporting period on the request.
• Ask for complete records, not an unlabeled total or screenshot.
• Give the client a requested response date that leaves room for review.
• Identify the approved delivery location and a responsible contact.
• Record missing, not-applicable and received-but-unreviewed items separately.

A requested document date is your planning date, not a replacement for a legal deadline. If the information is late, reassess the plan and communicate the issue. Do not mark the return ready solely because a request was sent.

3. Separate preparation, review and authorization

Example responsibilities for a GST/HST work item

Stage	Responsible person	Evidence of the next step
Collect records	Client contact / request owner	Required records available or exceptions documented
Prepare	Assigned preparer	Work ready for the designated reviewer
Review	Appropriate reviewer	Questions resolved or explicitly escalated
Submit	Authorized filer	Actual submission confirmation retained
Confirm payment	Agreed payment owner	Payment evidence or outstanding action recorded

Adapt these roles to the work agreed. In a small firm, one person may handle several steps, but each check is still needed. Agree on the client approvals and permissions required. Assigning a task does not give someone permission to access a CRA account or file a return.

4. Handle exceptions without hiding them in a completed task

Suppose records arrive but an unusual transaction still needs review. The collection task can show receipt while preparation or review remains open. Name the unresolved question and the person who will decide it. Do not treat a blank answer as a zero amount or assume that a client’s silence approves a tax treatment.

If the return for that period has already been filed, follow the correct process to change it. Editing your tracking notes is not enough. CRA guidance separates filing, checking a submission and changing a return. Record which action you actually took.

This example is about work visibility. It does not determine the right tax treatment, whether a particular credit can be claimed or whether a filing should proceed. Those decisions belong to the responsible professional and applicable rules.

5. Retain filing and payment evidence separately

“Prepared,” “submitted” and “paid” are different outcomes. After the authorized filer uses the appropriate filing channel, retain the confirmation and identify the relevant period. A task marked complete or an email saying “done” is not equivalent to evidence that CRA accepted a submission.

Similarly, filing a return does not prove that a required payment was made. Confirm who handles payment and retain the relevant evidence or next action. Use the client’s account and current CRA guidance to resolve uncertainties, rather than inferring a result from an internal dashboard.

• Link the reviewed work to the actual reporting period.
• Retain submission confirmation through the approved recordkeeping process.
• Record the separate payment responsibility and outcome.
• Carry unresolved follow-up into a clearly assigned task.
• Check the next reporting period before repeating the workflow.

6. Make the workflow visible in Bookwits

Bookwits Client Lists can organize GST/HST-related client work. Tasks can assign collection, review and follow-up, while Client Tasks and Documents help keep requests and supporting material associated with the right client. Use the Client Lists guide to understand the available controls.

Bookwits is used here for coordination. This article does not claim that it calculates GST/HST, validates credits, determines statutory deadlines or submits returns to CRA. Keep the actual accounting, authorization and filing processes explicit.
