6 worked Charity GST/HST Return 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 charity gst/hst return work, not a specific client's file.
Case Study 1 · Scaling without breaking
Second-Province Expansion Handled, $47,000 Of Cash Released — Interprovincial Marketing Agency, Windsor
Client: A marketing agency billing outside its home province · Where: Windsor, Ontario · Engagement: 3 weeks, fixed fee
Cash released$47,000
New registrationsComplete on day one
Compliance gapsNone
The situation — A marketing agency billing outside its home province, Windsor, Ontario
Revenue at a marketing agency billing outside its home province in Windsor, Ontario was up sharply and cash was tighter than ever. Underneath it sat HST charged at the home-province rate on sales into four different provinces.
What we did for A marketing agency billing outside its home province, Windsor, Ontario
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. Every new obligation — registration, remittance frequency, provincial filing — was set up before it was triggered, not after.
The result — A marketing agency billing outside its home province, Windsor, Ontario
$47,000 of cash was released from the working capital cycle, and the expansion completed with every registration and filing obligation covered from day one.
Case Study 2 · Cash and remittance control
$29,500 Of Working Capital Freed From The Tax Cycle — Mixed-Use Landlord, Calgary
Client: A residential landlord also renting commercial space · Where: Calgary, Alberta · Engagement: 7 weeks, fixed fee
Working capital freed$29,500
On-time remittancesEvery period since
Forecast horizon13 weeks
The situation — A residential landlord also renting commercial space, Calgary, Alberta
A residential landlord also renting commercial space in Calgary, Alberta was profitable on paper and short of cash every month. Export sales zero-rated with no shipping documentation behind them explained most of the gap.
What we did for A residential landlord also renting commercial space, Calgary, Alberta
We 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 and built a thirteen-week cash view so tax payments stopped competing with payroll for the same dollars.
The result — A residential landlord also renting commercial space, Calgary, Alberta
$29,500 was released back into working capital. Remittances have been on time every period since, and the forecast shows the tax outflow before it lands.
Case Study 3 · Backlog brought current
Collections Halted And $27,000 Cut From A 3-Year Backlog — Cross-Border SaaS Company, Surrey
Client: A SaaS company with Canadian and US customers · Where: Surrey, British Columbia · Engagement: 7 weeks, fixed fee
Balance reduced by$27,000
Backlog cleared3 years
CollectionsHalted
The situation — A SaaS company with Canadian and US customers, Surrey, British Columbia
By the time a SaaS company with Canadian and US customers in Surrey, British Columbia called, 3 years were outstanding and the CRA had assessed on estimates. Underneath it sat a commercial property purchase closed on the assumption no tax applied because the vendor was not registered.
What we did for A SaaS company with Canadian and US customers, Surrey, British Columbia
We reconstructed the records year by year and set a defensible input tax credit allocation between taxable and exempt supplies and documented the method for future filings. Each filing replaced an arbitrary assessment with a real one.
The result — A SaaS company with Canadian and US customers, Surrey, British Columbia
The account is current. Filing on real numbers rather than CRA estimates reduced the balance by $27,000, and a relief application addressed part of the accumulated interest.
Case Study 4 · Planning that cut the bill
$68,000 Cut From The Annual Tax Bill — US-Bound Exporter, Kitchener
Client: A manufacturer exporting to the US · Where: Kitchener, Ontario · Engagement: 5 weeks, fixed fee
First-year saving$68,000
RepeatsAnnually
Filing positionUnchanged in risk
The situation — A manufacturer exporting to the US, Kitchener, Ontario
A manufacturer exporting to the US in Kitchener, Ontario was compliant but paying more than it needed to. The prior year had been filed correctly and still left a registration threshold crossed nine months before anyone registered on the table.
What we did for A manufacturer exporting to the US, Kitchener, Ontario
We modelled the current position against the alternatives before changing anything, then tested the quick method against the account’s actual input tax credit history and stayed on the regular method where the credits were worth more.
The result — A manufacturer exporting to the US, Kitchener, Ontario
The change saved $68,000 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 · Structure rebuilt
Reorganisation Completed Tax-Deferred, $66,000 Saved Each Year — Multi-Province Online Retailer, Guelph
The situation — A multi-province online retailer, Guelph, Ontario
A multi-province online retailer in Guelph, Ontario had outgrown the structure it started with. A sales tax account filed annually while the CRA had moved the business to quarterly was the immediate problem; the longer-term one was that the structure blocked the next step.
What we did for A multi-province online retailer, Guelph, Ontario
We mapped the current structure, modelled the target, and filed the section 156 election for the related registrants, so supplies between them stopped carrying tax that served no purpose but cash-flow drag — with the tax-deferred elections filed on time and the supporting valuations documented.
The result — A multi-province online retailer, Guelph, Ontario
The reorganisation completed without triggering tax, and the new structure saves approximately $66,000 a year while removing the exposure the old one carried.
Case Study 6 · Objection and relief
Notice Of Objection Allowed In Full, $63,000 Reversed — Restaurant Group, Ottawa
Client: A restaurant group · Where: Ottawa, Ontario · Engagement: 4 weeks, fixed fee
Amount reversed$63,000
ObjectionAllowed in full
Account balanceNil
The situation — A restaurant group, Ottawa, Ontario
A restaurant group in Ottawa, Ontario had been reassessed for $63,000 and had 20 days left on the objection deadline. The reassessment rested on nil periods left unfiled, which held up the refund on the one period that mattered.
What we did for A restaurant group, Ottawa, Ontario
We filed the objection inside the deadline with a complete submission rather than a placeholder, and backdated the registration to the day the threshold was crossed, remitted the tax owing, and applied for relief on the penalty portion.
The result — A restaurant group, Ottawa, Ontario
The appeals officer allowed the objection in full. $63,000 was reversed and the account returned to a nil balance.
