Quarterly GST/HST review checklist for Canadian freelancers

Confirm the reporting period and both due dates

A GST/HST registrant must file a return for each reporting period. The filing and payment deadlines depend on whether the account is monthly, quarterly, or annual and, for some annual filers, on the business and fiscal year-end facts.

CRA currently states that monthly and quarterly returns and payments are generally due one month after the reporting period ends. Annual deadlines vary. If a due date falls on a Saturday, Sunday, or CRA-recognized public holiday, CRA applies its next-business-day rule.

Do not infer the period or deadline from a bookkeeping label. Confirm the reporting period and account details in the current CRA account or registration record, then preserve the exact period end, filing deadline, and payment deadline as three separate facts.

Close sales before touching the return

Reconcile the sales ledger to invoices, credit notes, refunds, and other adjustments for the reporting period. Keep the gross consideration, GST/HST collected or collectible, processor deductions, and net deposit separate so a smaller bank deposit does not erase part of the transaction trail.

For foreign-currency invoices, preserve the original currency and amount, conversion date, rate, source, method, and Canadian-dollar result. Recheck the same method and source used during the period rather than choosing a favourable rate after the quarter ends.

Classification remains a separate question. A foreign customer, a zero-dollar tax line, or a processor label does not by itself establish zero-rating, exemption, place of supply, or who made the supply.

• Match every sales-ledger row to an invoice, agreement, credit, or other source reference.
• Separate gross sales from GST/HST, fees, refunds, chargebacks, and deposits.
• Keep taxable, zero-rated, exempt, outside-Canada, and unresolved classifications distinct.
• Reconcile foreign-currency rows to documented Canadian-dollar conversions.

Review purchases before claiming an input tax credit

CRA says input tax credit eligibility depends on several conditions, including being a registrant in the relevant period, acquiring the property or service for commercial activities, having GST/HST paid or payable, obtaining sufficient documentary evidence before making the claim, and claiming within the applicable time limit.

A receipt showing tax is therefore only one part of the review. Confirm the purchaser, supplier, date, description, amount, tax information, business purpose, and any allocation between commercial and other use. The information required on supporting documents can vary with the transaction amount and circumstances.

Accounting methods can change the result. CRA notes that a person using the quick method generally cannot claim input tax credits for ordinary operating expenses, although some property may receive different treatment. Do not apply the ordinary checklist without confirming the actual method.

Reconcile the filing result to cash and evidence

A provider or bank deposit can combine sales, tax, fees, reserves, refunds, chargebacks, and foreign-exchange effects. Build a bridge from the sales and purchase records to the return calculation, and a separate bridge from the provider statement to actual cash received.

If a platform may be a reseller or merchant of record rather than only a payment processor, review the contract, invoice flow, tax role, and payout statement before mapping customer payments to the seller's return. A dashboard label does not decide the legal or accounting role.

Resolve unexplained differences before treating the quarter as closed. Keep sales-tax cash distinct from product-performance measures so the business review does not mistake money held for a tax obligation for earned product contribution.

Freeze a review record you can reproduce

Retain the working calculation, filing confirmation, payment reference, sales and purchase evidence, foreign-currency support, provider statements, and notes explaining every material adjustment. A later reviewer should be able to reproduce the path without relying on memory.

CRA says businesses generally need to retain GST/HST-related invoices and records for six years from the end of the year to which they relate, and may require longer retention in some situations. Confirm the rule that applies to the actual record before destruction.

The Thirty North Quarterly Review Workspace can organize a local supply log, FX evidence, backup, CSV export, and printable review record. It does not connect to CRA, determine input tax credit eligibility, prepare a GST/HST return, or replace the source documents.
