6 worked Quarterly GST/HST Filing case studies — the position a client typically comes to us with, what we do, and what it is worth. Each is an illustrative example built on the rules that apply to quarterly gst/hst filing work, not a specific client's file.
Case Study 1 · Scaling without breaking
Scaled To 76 Staff With $53,000 Of Working Capital Freed — Mixed-Use Landlord, Saskatoon
Client: A residential landlord also renting commercial space · Where: Saskatoon, Saskatchewan · Engagement: 7 weeks, fixed fee
Headcount reached76
Working capital freed$53,000
Missed deadlinesZero
The situation — A residential landlord also renting commercial space, Saskatoon, Saskatchewan
A residential landlord also renting commercial space in Saskatoon, Saskatchewan was growing fast — headcount to 76 in eighteen months — and the back office had not kept up. HST charged at the home-province rate on sales into four different provinces was the first thing to break.
What we did for A residential landlord also renting commercial space, Saskatoon, Saskatchewan
We rebuilt the sales ledger by customer province, applied the correct place-of-supply rate to each stream, and filed corrected returns before the CRA opened a review, and built the compliance calendar for the size the business was becoming rather than the size it had been.
The result — A residential landlord also renting commercial space, Saskatoon, Saskatchewan
The business reached 76 staff with no missed remittance and no late filing. $53,000 of working capital was freed in the process.
Case Study 2 · Deadline rescue
Filed On Time From A Standing Start, $57,000 Penalty Avoided — Wholesale Food Distributor, Brampton
The situation — A wholesale food distributor, Brampton, Ontario
A wholesale food distributor in Brampton, Ontario came to us 8 weeks before its filing deadline with input tax credits claimed on the exempt side of a mixed-supply business. A late filing would have triggered a penalty of roughly $57,000 before interest.
What we did for A wholesale food distributor, Brampton, Ontario
We worked backwards from the deadline. We filed the section 156 election for the related registrants, so supplies between them stopped carrying tax that served no purpose but cash-flow drag, prioritising the items that actually gated the filing and deferring everything that did not.
The result — A wholesale food distributor, Brampton, Ontario
The return was filed on time and complete. The $57,000 penalty never arose, and the compliance calendar we set means the next deadline is scheduled rather than discovered.
Case Study 3 · Sale and succession
$560,000 Sheltered By The Lifetime Capital Gains Exemption — Late GST/HST Registrant, Red Deer
Client: A seller who crossed the registration threshold before registering · Where: Red Deer, Alberta · Engagement: 10 weeks, fixed fee
Gain sheltered$560,000
ClosingOn schedule
Share qualificationMet
The situation — A seller who crossed the registration threshold before registering, Red Deer, Alberta
A seller who crossed the registration threshold before registering in Red Deer, Alberta had an offer on the table and 26 months to close. The shares did not qualify for the capital gains exemption, and a shareholder loan balance that would have been picked up as income on closing was part of the reason.
What we did for A seller who crossed the registration threshold before registering, Red Deer, Alberta
We purified the corporation so the shares met the qualifying tests, then backdated the registration to the day the threshold was crossed, remitted the tax owing, and applied for relief on the penalty portion well ahead of the closing date.
The result — A seller who crossed the registration threshold before registering, Red Deer, Alberta
The sale closed on schedule with $560,000 sheltered by the lifetime capital gains exemption across the shareholders.
Case Study 4 · Planning that cut the bill
$11,000 Cut From The Annual Tax Bill — Interprovincial Marketing Agency, Moncton
Client: A marketing agency billing outside its home province · Where: Moncton, New Brunswick · Engagement: 8 weeks, fixed fee
First-year saving$11,000
RepeatsAnnually
Filing positionUnchanged in risk
The situation — A marketing agency billing outside its home province, Moncton, New Brunswick
A marketing agency billing outside its home province in Moncton, New Brunswick was compliant but paying more than it needed to. The prior year had been filed correctly and still left a commercial property purchase closed on the assumption no tax applied because the vendor was not registered on the table.
What we did for A marketing agency billing outside its home province, Moncton, New Brunswick
We modelled the current position against the alternatives before changing anything, then self-assessed the tax on the real property acquisition in the correct reporting period and claimed the offsetting input tax credit in the same return.
The result — A marketing agency billing outside its home province, Moncton, New Brunswick
The change saved $11,000 in the first year and repeats annually. Nothing about the filings became more aggressive; the position is simply the one the rules already allowed.
Case Study 5 · Objection and relief
Desk-Review Assessment Of $87,000 Vacated — Exempt-Supply Clinic, Guelph
Client: A health clinic making exempt supplies · Where: Guelph, Ontario · Engagement: 3 weeks, fixed fee
Assessment vacated$87,000
Supporting recordsNow on file
AccountCleared
The situation — A health clinic making exempt supplies, Guelph, Ontario
A health clinic making exempt supplies in Guelph, Ontario was carrying $87,000 of penalties and interest arising from a registration threshold crossed nine months before anyone registered, much of it accumulated during a period the CRA itself had delayed.
What we did for A health clinic making exempt supplies, Guelph, Ontario
We set a defensible input tax credit allocation between taxable and exempt supplies and documented the method for future filings and framed the relief application on the specific grounds the CRA guidelines recognise rather than on general hardship.
The result — A health clinic making exempt supplies, Guelph, Ontario
The assessment was vacated. $87,000 came off the account, and the documentation now on file makes the same position straightforward to defend next time.
Case Study 6 · Missed incentive claimed
$83,000 Credit Claim Filed And Accepted Without Adjustment — Used-Equipment Dealer, Calgary
Client: A used-equipment dealer · Where: Calgary, Alberta · Engagement: 6 weeks, fixed fee
Claim value$83,000
AcceptedWithout adjustment
RepeatableAnnually
The situation — A used-equipment dealer, Calgary, Alberta
A used-equipment dealer in Calgary, Alberta assumed the credits did not apply to a business its size. Export sales zero-rated with no shipping documentation behind them meant they had applied all along.
What we did for A used-equipment dealer, Calgary, Alberta
We identified the qualifying activity, built the documentation to support it, and brought the nil and missing periods current so the account was clean before the refund claim was filed.
The result — A used-equipment dealer, Calgary, Alberta
$83,000 recovered. Because the eligibility analysis is on file, the same claim can be repeated each year with a fraction of the effort.
