Partnership GST/HST Filing Case Studies

6 worked Partnership 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 partnership gst/hst filing work, not a specific client's file.

Case Study 1 · Planning that cut the bill

$34,000 Saved By Correcting What Prior Filings Had Missed — Interprovincial Construction Supplier, Kelowna

Client: A construction supplier selling into three provinces  ·  Where: Kelowna, British Columbia  ·  Engagement: 7 weeks, fixed fee

Saving identified$34,000
RecurringYes
Positions documentedAll

The situation — A construction supplier selling into three provinces, Kelowna, British Columbia

A construction supplier selling into three provinces in Kelowna, British Columbia asked for a second opinion on partnership GST/HST filing. That followed three years of rising tax. The review found export sales zero-rated with no shipping documentation behind them.

What we did for A construction supplier selling into three provinces, Kelowna, British Columbia

We built the comparison first: current structure against two alternatives. Then we assembled the export documentation, restored zero-rating on the qualifying sales, and reduced the proposed assessment.

The result — A construction supplier selling into three provinces, Kelowna, British Columbia

First-year saving of $34,000, with the same benefit recurring. Every position taken is documented and supported in the file.

Case Study 2 · Sale and succession

Intergenerational Transfer Completed With $640,000 Deferred — Exempt-Supply Clinic, Mississauga

Client: A health clinic making exempt supplies  ·  Where: Mississauga, Ontario  ·  Engagement: 11 weeks, fixed fee

Tax deferred$640,000
TransferCompleted
RecordsReview-ready

The situation — A health clinic making exempt supplies, Mississauga, Ontario

A generational transfer at a health clinic making exempt supplies in Mississauga, Ontario had been discussed for years without a plan. A shareholder loan balance that would have been picked up as income on closing meant the transfer as contemplated would have been fully taxable.

What we did for A health clinic making exempt supplies, Mississauga, Ontario

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. We sequenced the steps so each one was complete and documented before the next depended on it.

The result — A health clinic making exempt supplies, Mississauga, Ontario

$640,000 of tax was deferred through the transfer, and the successor generation took over a corporation whose records stood up to review.

Case Study 3 · Deadline rescue

9-Week Turnaround Beat The Deadline And Saved $57,000 — Mixed-Supply Practice, Halifax

Client: A professional practice with exempt and taxable supplies  ·  Where: Halifax, Nova Scotia  ·  Engagement: 9 weeks, fixed fee

Late-filing penalty avoided$57,000
Filed with10 days to spare
Next yearPapers ready

The situation — A professional practice with exempt and taxable supplies, Halifax, Nova Scotia

A professional practice with exempt and taxable supplies in Halifax, Nova Scotia was weeks away from the deadline for partnership GST/HST filing. Behind that sat a registration threshold crossed nine months before anyone registered. The exposure if the date slipped was around $57,000.

What we did for A professional practice with exempt and taxable supplies, Halifax, Nova Scotia

We 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 filing went in complete rather than provisional, so there was no amended return to follow.

The result — A professional practice with exempt and taxable supplies, Halifax, Nova Scotia

Filed with 10 days to spare. $57,000 in late-filing penalties avoided, and the working papers are ready for the following year.

Case Study 4 · Scaling without breaking

Growth Handled Without A Missed Filing, $99,000 Freed — Restaurant Group, Kitchener

Client: A restaurant group  ·  Where: Kitchener, Ontario  ·  Engagement: 4 weeks, fixed fee

Cash freed$99,000
Compliance failuresNone
ReportingMonthly

The situation — A restaurant group, Kitchener, Ontario

A restaurant group in Kitchener, Ontario was opening in a second province. That meant different filing obligations and a different payroll regime. HST charged at the home-province rate on sales into four different provinces already sat in the file.

What we did for A restaurant group, Kitchener, Ontario

We backdated the registration to the date the business stopped being a small supplier, remitted the tax owing, and applied for relief on the penalty portion. We then put monthly reporting in place. That let the owner see the cash effect of growth while there was still time to act on it.

The result — A restaurant group, Kitchener, Ontario

Growth was absorbed without a compliance failure. $99,000 of cash was released, and the monthly reporting now flags a problem while it is still small.

Case Study 5 · Backlog brought current

Collections Halted And $30,000 Cut From A 7-Year Backlog — Wholesale Food Distributor, Guelph

Client: A wholesale food distributor  ·  Where: Guelph, Ontario  ·  Engagement: 10 weeks, fixed fee

Balance reduced by$30,000
Backlog cleared7 years
CollectionsHalted

The situation — A wholesale food distributor, Guelph, Ontario

By the time a wholesale food distributor in Guelph, Ontario called, 7 years were outstanding. The CRA had assessed on estimates. Underneath it sat nil periods left unfiled, which held up the refund on the one period that mattered.

What we did for A wholesale food distributor, Guelph, Ontario

We reconstructed the records year by year. 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. Each filing replaced an arbitrary assessment with a real one.

The result — A wholesale food distributor, Guelph, Ontario

The account is current. Filing on real numbers rather than CRA estimates reduced the balance by $30,000, and a relief application addressed part of the accumulated interest.

Case Study 6 · Records and systems rebuilt

Month-End Close Cut From 9 Weeks To 7 Days — Multi-Province Online Retailer, Edmonton

Client: A multi-province online retailer  ·  Where: Edmonton, Alberta  ·  Engagement: 3 weeks, fixed fee

Close time before9 weeks
Close time after7 days
Year-endReview, not rebuild

The situation — A multi-province online retailer, Edmonton, Alberta

The accounting file at a multi-province online retailer in Edmonton, Alberta had a weak foundation. It was built on a commercial property purchase closed on the assumption no tax applied because the vendor was not registered. The year-end had taken 9 weeks each of the last three years.

What we did for A multi-province online retailer, Edmonton, Alberta

We brought the nil and missing periods current so the account was clean before the refund claim was filed. We also moved the reconciliations into the monthly cycle, so the year-end stopped being a rebuild.

The result — A multi-province online retailer, Edmonton, Alberta

The file reconciles. Month-end closes in 7 days instead of 9 weeks, and the year-end is a review rather than a reconstruction.
