Where Sales Tax Returns Get Complicated


Get a written scope that identifies the returns, periods, approvals, and payment responsibilities before work starts.

What Our Sales Tax Filing Service Covers

We start with the accounts and reporting periods you need filed. Then we review your books, supporting records, and previous returns to see what’s ready and what needs work.

GST/HST return preparation and filing

Tie sales, GST/HST collected or collectible, and eligible input tax credits to your records. We prepare the return and file it when submission is included and authorization is in place.

B.C. PST and Saskatchewan PST returns

We review provincial sales and tax records separately for each account in scope and prepare the applicable PST returns using the province’s reporting requirements.

Manitoba Retail Sales Tax (RST)

We review the Manitoba sales and tax records for your RST return. Manitoba RST is filed separately from the federal GST/HST return.

Input tax credit review

We review GST/HST paid or payable on eligible business purchases and check for supporting invoices. We flag unclear items and missing documentation before the return is finalized.

Sales tax reconciliation

Compare sales reports, purchase records, refunds, and tax accounts. We investigate differences between your accounting reports and what you expect to report. For an online store example, see our guide to Shopify and QuickBooks reports to review before filing GST/HST.

Overdue returns and bookkeeping catch-up

We identify unfiled periods and review which records need to be reconciled first. We quote catch-up work separately when the books need more than a filing review.

Reporting periods and filing deadlines

We confirm the periods and due dates for each account in scope. We distinguish the filing deadline from the payment deadline and flag instalments for review where applicable.

Tax codes and sales across provinces

We compare your invoices, sales channels, and accounting tax codes. If a sale raises questions about where it’s taxed, exemptions, or provincial registration, we flag it for review before filing.

Return summaries and filing records

Keep the return figures, supporting reports, and any filing confirmation together. We identify the payment amount and due date when a balance is payable.

Accounting Tools and Records We Use

We work in QuickBooks Online or Xero and review sales, payment, and purchase records from your existing systems. Paperless Books uses an audit ready system to match source files to transactions in Quickbooks and Xero. This is in compliance with CRA’s sales tax filing expectations.

Frequently Asked Questions

What records do you need to prepare my sales tax return?

We typically need your sales and purchase records, previous returns, tax account details, and reporting dates. If the books aren’t reconciled, we also need the statements and reports required to explain the balances.

How much does GST/HST or PST filing cost?

Pricing depends on the accounts, number of periods, and condition of your books. We confirm the fee in writing and quote any bookkeeping catch-up separately. See our bookkeeping and sales tax service plans.

Do GST/HST and PST go on the same return?

They’re separate filings. GST/HST is reported to the CRA. B.C. PST, Saskatchewan PST, and Manitoba RST have separate provincial accounts, returns, and deadlines.

Can you help with overdue GST/HST or PST returns?

Yes. We check which periods are outstanding and whether the books need cleanup first. We agree on the filing order and fee before starting.

Do I need to file a GST/HST return if I had no sales?

If you’re registered for GST/HST, you generally still need to file a return for each reporting period even when there’s no activity or no balance owing. Provincial return requirements are checked separately.

How do we share records and authorize filing?

We agree on access and how to share records during onboarding. We confirm whether you’ll submit the return yourself or authorize us to submit it for you.

How do you review GST/HST input tax credits?

We review the GST/HST on eligible business purchases and the invoices supporting those amounts. If documentation or eligibility is unclear, we flag the item before including it.

When are my sales tax return and payment due?

Use the filing and payment dates that apply to your account and reporting period. We confirm both dates for the returns in scope and tell you who is responsible for paying any balance.
