Company Saves on QST Remittances with Simplified Filing

A small Montreal service company was drowning in paperwork. Every GST/QST filing period felt like a battle dozens of invoices, endless categorization, complex ITC/ITR calculations, and constant reconciliation issues. Despite all the work, refunds were often questioned or delayed. Then Mackisen stepped in and discovered something the business had never considered: the Quick Method.
By switching to the GST/QST Quick Method, the business dramatically simplified compliance and saved thousands in QST remittances. Here is how it happened.
The Situation: Traditional Filing Was Draining Time and Money
The company:
• tracked every ITC and ITR manually
• had messy documentation
• filed returns inconsistently
• dealt with refund delays each quarter
• spent too much time reconciling expenses
• mixed personal and business purchases
• had trouble keeping QuickBooks tax codes consistent
Traditional GST/QST filing had become an exhausting chore and prone to error.
The Turning Point: A CPA Review
During a routine review, Mackisen noticed that:
• the business had low expenses relative to sales
• most expenses did not generate significant ITCs/ITRs
• taxable supplies were consistent and predictable
• the company’s activity fell squarely within Quick Method eligibility
The owner had no idea this option existed.
How The Quick Method Changed Everything
Step 1 — Confirming Eligibility
Mackisen verified that the business:
• had under $400,000 in annual taxable revenues
• did not fall into an excluded profession
• had a simple service-based model
• could legally elect the Quick Method
The company was an ideal candidate.
Step 2 — Filing the Quick Method Election
Mackisen filed:
• GST74 for CRA
• FP-505. D. A for Revenu Québec
The Quick Method took effect at the start of the next reporting period.
Step 3 — Reconfiguring Accounting Software
The team updated:
• QuickBooks tax codes
• invoice templates
• reporting settings
• remittance calculations
The system now automatically applied Quick Method logic.
Step 4 — Training the Owner
The business learned:
• how the remittance percentages work
• which expenses still qualify for ITCs
• how to treat capital purchases
• how to file Quick Method returns effortlessly
The owner gained complete confidence.
The Outcome: Big Savings and Zero Stress
Switching to the Quick Method delivered:
• thousands in QST remittance savings
• faster rebate cycles
• almost no documentation burden
• clean, simple filings
• fewer questions from Revenu Québec
• no need to track every ITC and ITR
• reduced audit risk
• more predictable cash flow
The business owner now spends minutes not hours preparing GST/QST returns.
Key Lessons
• The Quick Method is one of the most underused tax strategies for small businesses
• Service-based companies with low expenses save the most
• Switching requires proper filing and software setup
• Many businesses waste time tracking ITCs they don’t need
• A CPA review can uncover major savings
