Import and Export GST Accounting Case Studies

6 worked Import and Export GST Accounting 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 import and export gst accounting work, not a specific client's file.

Case Study 1 · Objection and relief

Notice Of Objection Allowed In Full, $93,000 Reversed — Used-Equipment Dealer, Mississauga

Client: A used-equipment dealer. Where: Mississauga, Ontario. Engagement: 10 weeks, fixed fee.

Amount reversed$93,000
ObjectionAllowed in full
Account balanceNil

Case 1: the situation

A used-equipment dealer in Mississauga, Ontario had been reassessed for $93,000. 13 days were left on the objection deadline. The reassessment rested on a registration threshold crossed nine months before anyone registered.

Case 1: what we did

We filed the objection inside the deadline with a complete submission rather than a placeholder. Alongside it, 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.

Case 1: the result

The appeals officer allowed the objection in full. $93,000 was reversed and the account returned to a nil balance.

Case Study 2 · Backlog brought current

$28,000 Of Arbitrary Assessments Vacated After 6 Years — Mixed-Supply Practice, Edmonton

Client: A professional practice with exempt and taxable supplies. Where: Edmonton, Alberta. Engagement: 9 weeks, fixed fee.

Arbitrary tax vacated$28,000
Years brought current6
Account statusCurrent

Case 2: the situation

6 years of unfiled returns had turned into notional assessments at a professional practice with exempt and taxable supplies in Edmonton, Alberta. Underneath lay management fees between two related registrants carrying tax that only ever went out and came back. Collections had already started.

Case 2: what we did

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. We then filed every outstanding year in chronological order so the CRA could vacate the notional assessments cleanly.

Case 2: the result

All 6 years were accepted as filed. $28,000 of arbitrarily assessed tax was vacated, collections action stopped, and the account is current for the first time in 6 years.

Case Study 3 · Missed incentive claimed

$56,000 In Credits Claimed That Prior Filings Had Missed — Digital Platform Seller, Ottawa

Client: A platform seller collecting tax at checkout. Where: Ottawa, Ontario. Engagement: 11 weeks, fixed fee.

Credits claimed$56,000
Years adjusted7
Review outcomeNo adjustment

Case 3: the situation

A platform seller collecting tax at checkout in Ottawa, Ontario had been filing for 7 years. In that time, the incentives its activity qualified for were never claimed. Behind that sat nil periods left unfiled, which held up the refund on the one period that mattered.

Case 3: what we did

We tested each activity against the eligibility criteria rather than the description on the invoice. Then 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.

Case 3: the result

$56,000 in credits claimed, with the open prior years adjusted as well. The claim passed review without adjustment.

Case Study 4 · Scaling without breaking

Growth Handled Without A Missed Filing, $149,000 Freed — Wholesale Food Distributor, Winnipeg

Client: A wholesale food distributor. Where: Winnipeg, Manitoba. Engagement: 6 weeks, fixed fee.

Cash freed$149,000
Compliance failuresNone
ReportingMonthly

Case 4: the situation

A wholesale food distributor in Winnipeg, Manitoba was opening in a second province. That meant different filing obligations and a different payroll regime. A commercial property purchase closed on the assumption no tax applied because the vendor was not registered already sat in the file.

Case 4: what we did

We assembled the export documentation, restored zero-rating on the qualifying sales, and reduced the proposed assessment. 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.

Case 4: the result

Growth was absorbed without a compliance failure. $149,000 of cash was released, and the monthly reporting now flags a problem while it is still small.

Case Study 5 · Cash and remittance control

Remittance Schedule Corrected, $121,000 Refunded — Freight Brokerage, Hamilton

Client: A freight brokerage. Where: Hamilton, Ontario. Engagement: 5 weeks, fixed fee.

Overpayment refunded$121,000
Late remittances sinceZero
ScheduleAutomated

Case 5: the situation

Remittances at a freight brokerage in Hamilton, Ontario were consistently late by a few days. That was enough to trigger penalties every quarter. Behind it sat export sales zero-rated with no shipping documentation behind them.

Case 5: what we did

We set a defensible input tax credit allocation between taxable and exempt supplies and documented the method for future filings. Then we moved the remittance dates into a scheduled process rather than a monthly decision.

Case 5: the result

Penalties stopped from the following remittance onwards, and $121,000 of overpaid instalments was refunded.

Case Study 6 · Deadline rescue

Filed On Time From A Standing Start, $29,500 Penalty Avoided — Late GST/HST Registrant, Surrey

Client: A seller who crossed the registration threshold before registering. Where: Surrey, British Columbia. Engagement: 5 weeks, fixed fee.

Penalty avoided$29,500
Turnaround5 weeks
FiledOn time

Case 6: the situation

A seller who crossed the registration threshold before registering in Surrey, British Columbia came to us 5 weeks before its filing deadline. The file came with nil periods left unfiled, which held up the refund on the one period that mattered. A late filing would have triggered a penalty of roughly $29,500 before interest.

Case 6: what we did

We worked backwards from the deadline. We rebuilt the sales ledger by customer province and applied the correct place-of-supply rate to each stream. We filed corrected returns before the CRA opened a review. We prioritised the items that actually gated the filing and deferred everything that did not.

Case 6: the result

The return was filed on time and complete. The $29,500 penalty never arose, and the compliance calendar we set means the next deadline is scheduled rather than discovered.
