Avoid the Last-Minute Scramble — 5 Organization Tips to Prepare for TPS/TVQ (GST/QST) Deadlines

Filing your TPS/TVQ (GST/QST) returns doesn’t have to feel like a race against the clock. With the right organization habits, you can stay ahead of deadlines, reduce stress, and ensure every submission to Revenu Québec and CRA is accurate, complete, and penalty-free. Mackisen CPA Montreal shares five proven strategies to help you file with confidence not panic.
Why Organization Is the Key to Stress-Free TPS/TVQ Filing
Too many Quebec business owners wait until the last week (or day) before the filing deadline to pull together invoices, receipts, and reports. The result? Missing documents, miscalculations, and sleepless nights sometimes followed by late penalties or lost refunds.
Under the Excise Tax Act and Tax Administration Act, every business must file its TPS/TVQ (GST/QST) returns on time. But being organized isn’t just about avoiding fines it’s about controlling your cash flow, improving financial accuracy, and building trust with Revenu Québec and the CRA.
A business that files early and accurately is seen as compliant, disciplined, and low-risk and that reputation pays dividends.
Tip 1 — Schedule Your TPS/TVQ Filing Dates in Advance
The first step in organization is simple: mark your deadlines. Whether you file monthly, quarterly, or annually, record all your TPS/TVQ (GST/QST) due dates for the next 12 months and add reminders to your phone or calendar system.
Your filing deadlines depend on your reporting frequency:
Monthly filers: Return due the last day of the following month.
Quarterly filers: One month after quarter-end.
Annual filers: Three months after fiscal year-end.
Mackisen CPA Montreal recommends setting alerts 10 days before every due date. This buffer gives you time to review documents, double-check calculations, and file early not at the last minute.
Tip 2 — Keep All Receipts and Invoices in One Place
Every GST/QST return depends on accurate documentation. If you can’t find receipts, you can’t claim Input Tax Credits (ITCs) or Input Tax Refunds (ITRs) meaning you lose money unnecessarily.
Use cloud-based accounting systems like QuickBooks, Xero, or Sage to scan and store receipts the moment you receive them. Create folders labeled by month or quarter, and separate:
Sales invoices (TPS/TVQ collected)
Purchase receipts (TPS/TVQ paid)
Credit notes or refunds
Mackisen CPA Montreal helps clients set up automated systems that link these records directly to CRA and Revenu Québec accounts eliminating the chaos of paper files.
Tip 3 — Reconcile Monthly (Even If You File Quarterly or Annually)
One of the biggest filing mistakes is waiting until the end of the quarter or year to reconcile accounts. This creates rushed, error-prone reporting.
Instead, review and reconcile your GST/QST transactions monthly:
Match invoices to payments.
Check that GST/QST collected matches what’s in your accounting software.
Verify ITC/ITR eligibility and totals.
This monthly discipline takes 30 minutes but saves hours of stress later — and prevents filing errors that could trigger a Revenu Québec review.
Tip 4 — File Electronically and Early
Paper returns are a relic of the past they take weeks to process and risk delays or errors. Filing electronically through Mon dossier pour les entreprises (Revenu Québec) and CRA My Business Account ensures:
Immediate confirmation numbers
Faster refunds
Secure digital recordkeeping
Filing early also gives you flexibility to correct or amend your return if needed without facing a missed deadline. Mackisen CPA Montreal always files electronically, providing clients with confirmation receipts for audit protection and peace of mind.
Tip 5 — Delegate or Automate — Don’t Do It Alone
Managing TPS/TVQ (GST/QST) filings on your own can quickly become overwhelming, especially when you’re running a growing business. Missing one small detail can mean costly penalties.
Working with a CPA ensures every number aligns with the Excise Tax Act and Tax Administration Act. Mackisen CPA Montreal automates every step from document tracking to final submission so your filings are always:
Accurate and verified by professionals
Submitted before every deadline
Fully compliant with Revenu Québec and CRA
Delegating to professionals isn’t an expense — it’s an investment in accuracy, time, and peace of mind.
Real Example — From Last-Minute Panic to Perfect Routine

Result: zero penalties, faster refunds, and full compliance. “I used to dread tax season,” he said. “Now I don’t even think about it.”
