GST / HST / QST Services
GST, HST and QST handled end to end — accurate registration, filing and remittance across every Canadian province, on time.
Overview
GST / HST / QST Services for Canada
Canada's indirect tax regime is layered and unforgiving: federal GST, harmonized HST in five provinces, and Quebec's separately administered QST each carry their own rates, place-of-supply rules, and filing calendars. A single miscoded invoice or missed deadline can trigger interest and penalties. AccountsUp manages the entire lifecycle — registration, transaction-level rate coding, input tax credit recovery, remittance, and period-end reconciliation — so nothing slips.
Rather than bolting on another portal, we work inside the accounting stack you already run — QuickBooks, Xero, NetSuite, or Sage — mapping tax codes to your chart of accounts and reconciling every filing back to the general ledger. A dedicated team pairs with AI-assisted checks that flag rate mismatches and unclaimed credits before a return is ever submitted to the CRA or Revenu Québec.
- A faster, cleaner period-end close with fewer manual adjustments
- Fewer late-filing penalties and interest charges from the CRA and Revenu Québec
- Higher input tax credit and ITR recovery you would otherwise leave on the table
- Audit-ready working papers and reconciliations for every filing period
What's included
Everything the gst / hst / qst services engagement covers
GST/HST & QST Registration
We register your business with the CRA (Form RC1) and Revenu Québec, set the right filing frequency, and handle voluntary, non-resident, and multi-entity registrations.
Place-of-Supply Rate Calculation
We apply the correct GST, HST, or QST rate to every transaction based on customer location and supply type, eliminating over- and under-charging.
Input Tax Credit & ITR Recovery
We identify and substantiate every recoverable input tax credit and Quebec ITR, applying eligibility and documentation rules correctly so you never leave eligible refunds unclaimed.
Return Preparation & Filing
We prepare and file GST34, RC7200, and Quebec FP-500 returns through GST/HST NETFILE, My Business Account, and Revenu Québec's online services, matched to your filing period.
Remittance Management
We calculate net tax, schedule instalments, and remit on time to both the CRA and Revenu Québec, protecting you from interest and late penalties.
Period-End Reconciliation
We reconcile tax collected, input tax credits, and GL control accounts against each filed return, surfacing variances before they become audit exposures.
Audit Support & CRA/RQ Correspondence
We respond to notices, assemble audit-ready working papers, and manage assessments and objections with the CRA and Revenu Québec on your behalf.
Cross-Border & Digital Economy Compliance
We manage non-resident registration, self-assessment on imported services, and the simplified GST/HST rules for digital platforms and cross-border supplies.
Why AccountsUp
The advantage of gst / hst / qst services done right
A Dedicated Indirect-Tax Team
You get a named team fluent in CRA and Revenu Québec rules — not a rotating queue — who learn your business and its filing patterns.
AI-Assisted Accuracy
AI-assisted checks scan every return for rate mismatches, duplicate credits, and coding errors, catching problems human review alone can miss before submission.
Works Inside Your Stack
We operate directly in QuickBooks, Xero, NetSuite, or Sage, so there is no new portal to learn and no data to migrate.
On-Time, Penalty-Free Filings
Every return and remittance is tracked against a compliance calendar with built-in buffers, so deadlines with the CRA and Revenu Québec are never missed.
Enterprise-Grade Security
Your financial data stays protected by role-based access, multi-factor authentication, encryption, and audit trails inside a controlled, office-only working environment.
Multi-Province, Multi-Entity Coverage
Whether you sell into one province or all thirteen jurisdictions, we handle every rate, registration, and return under a single coordinated engagement.
AI-powered, expert-led
The reliability of an in-house team, without the overhead
Most providers hand you software or a junior preparer; AccountsUp gives you both a dedicated team of Canadian indirect-tax specialists and an AI-assisted review layer that catches rate mismatches and unclaimed credits before filing. We work inside the accounting stack you already run, protect your data with enterprise-grade, office-only controls, and reconcile every return to your ledger — turning GST, HST, and QST from a recurring risk into a controlled, predictable process.

Stack Integration & Tax-Code Mapping

Questions
GST / HST / QST Services, answered
When does my business need to register for GST/HST and QST?
You must register for GST/HST once worldwide taxable revenue exceeds $30,000 over four consecutive quarters; QST follows a similar Quebec threshold. Voluntary early registration can unlock input tax credits sooner. We assess your thresholds, recommend timing, and complete every registration with the CRA and Revenu Québec.
How is QST different from GST/HST, and why does it matter?
QST is Quebec's provincial tax, administered separately by Revenu Québec rather than the CRA, with its own registration, return (FP-500), and input tax refund rules. Its ITR eligibility and documentation requirements diverge from the federal ITC regime in ways that are easy to miss. Handling QST as if it mirrors GST/HST is a common, costly error we prevent.
Do you work in our existing accounting software?
Yes. We work directly inside QuickBooks, Xero, NetSuite, and Sage, mapping tax codes to your chart of accounts rather than asking you to adopt a new platform. There is no migration, no parallel system, and your team keeps full visibility into every entry we make.
How do you keep our financial data secure?
Your data is protected by multi-factor authentication, role-based access controls, encryption in transit and at rest, and complete audit trails. Our teams operate from secured, office-only facilities with no removable media. These controls align with SOC 2 and ISO 27001 practices and pre-empt the top outsourcing concern.
How is the service priced?
Engagements start from a fixed monthly fee scoped to your transaction volume, number of registrations, and filing frequency. Multi-province or QST-inclusive businesses sit in a higher tier reflecting added complexity. You receive a transparent quote after a short discovery call — no per-hour surprises or hidden charges.
Can you handle non-resident or digital-economy registration?
Yes. We register non-resident vendors, set up simplified GST/HST accounts for digital platforms, and manage self-assessment on imported services. If you sell into Canada from abroad or supply digital products to Canadian consumers, we ensure you collect, file, and remit correctly across every jurisdiction.
