6 worked Ontario Employer Health Tax 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 ontario employer health tax filing work, not a specific client's file.
Case Study 1 · Scaling without breaking
Growth Handled Without A Missed Filing, $130,000 Freed — Seasonal Landscaping Employer, Kelowna
Client: A landscaping company with seasonal staff · Where: Kelowna, British Columbia · Engagement: 7 weeks, fixed fee
Cash freed$130,000
Compliance failuresNone
ReportingMonthly
The situation — A landscaping company with seasonal staff, Kelowna, British Columbia
A landscaping company with seasonal staff in Kelowna, British Columbia was opening in a second province. That meant different filing obligations and a different payroll regime. T4s that did not agree to the payroll register or the general ledger already sat in the file.
What we did for A landscaping company with seasonal staff, Kelowna, British Columbia
We reconciled the payroll register, general ledger and T4 summary to the cent, then filed the amended slips. 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 landscaping company with seasonal staff, Kelowna, British Columbia
Growth was absorbed without a compliance failure. $130,000 of cash was released, and the monthly reporting now flags a problem while it is still small.

RecurringYes
Positions documentedAll
The situation — A security services contractor, Vancouver, British Columbia
A security services contractor in Vancouver, British Columbia asked for a second opinion on Ontario employer health tax filing. That followed three years of rising tax. The review found long-term contractors who met every test for employment.
What we did for A security services contractor, Vancouver, British Columbia
We built the comparison first: current structure against two alternatives. Then we paid the accrued bonus inside the 180-day window and kept the deduction in the year it was accrued.
The result — A security services contractor, Vancouver, British Columbia
First-year saving of $58,000, with the same benefit recurring. Every position taken is documented and supported in the file.
Case Study 3 · Cash and remittance control
$73,000 Of Working Capital Freed From The Tax Cycle — Stock-Option Tech Team, Hamilton
Client: A growing tech team with stock options · Where: Hamilton, Ontario · Engagement: 10 weeks, fixed fee
Working capital freed$73,000
On-time remittancesEvery period since
Forecast horizon13 weeks
The situation — A growing tech team with stock options, Hamilton, Ontario
A growing tech team with stock options in Hamilton, Ontario was profitable on paper and short of cash every month. T4 slips filed weeks after the deadline with no relief request made on the per-slip penalty explained most of the gap.
What we did for A growing tech team with stock options, Hamilton, Ontario
We corrected the CPP and EI withholding for the balance of the year. We set the employee up to recover the over-deduction on the personal return. We also built a thirteen-week cash view so tax payments stopped competing with payroll for the same dollars.
The result — A growing tech team with stock options, Hamilton, Ontario
$73,000 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 4 · Records and systems rebuilt
16 Months Reconciled And $11,500 Of Input Tax Recovered — Two-Province Retail Chain, Burnaby
Client: A retail chain across two provinces · Where: Burnaby, British Columbia · Engagement: 4 weeks, fixed fee
Months reconciled16
Input tax recovered$11,500
Close time4 days
The situation — A retail chain across two provinces, Burnaby, British Columbia
Nothing reconciled at a retail chain across two provinces in Burnaby, British Columbia. Every filing started with 16 months of cleanup. The file was carrying a bonus accrued to bring the year-end tax bill down and still unpaid more than a year later.
What we did for A retail chain across two provinces, Burnaby, British Columbia
We rebuilt from source rather than correcting on top of the existing file. We filed the outstanding slips and summary and requested relief on the per-slip penalty with the reasons documented in writing. Then we set the routine that keeps it clean.
The result — A retail chain across two provinces, Burnaby, British Columbia
16 months reconciled to the bank. The close now takes 4 days, and $11,500 of previously unclaimable input tax was recovered in the process.
Case Study 5 · Deadline rescue
$18,000 Late-Filing Penalty Cancelled On Relief Application — Mixed-Crew Construction Firm, Victoria
Client: A construction firm with union and non-union crews · Where: Victoria, British Columbia · Engagement: 3 weeks, fixed fee
Penalty cancelled$18,000
Relief applicationGranted
ReturnAccepted as filed
The situation — A construction firm with union and non-union crews, Victoria, British Columbia
A construction firm with union and non-union crews in Victoria, British Columbia had already missed one deadline and was about to miss a second. Behind it sat a director facing a personal assessment for unremitted source deductions. A penalty of $18,000 was accruing.
What we did for A construction firm with union and non-union crews, Victoria, British Columbia
We split the work into what had to happen before the deadline and what could follow it. Then we wrote each pay code against its income tax, CPP and EI treatment. That way, a new benefit could not reach the payroll without a decision on how it was withheld.
The result — A construction firm with union and non-union crews, Victoria, British Columbia
The outstanding return was accepted as filed, and the taxpayer relief application cancelled $18,000 of the penalty already assessed on the earlier year.
Case Study 6 · Objection and relief
Notice Of Objection Allowed In Full, $120,000 Reversed — Home-Care Agency, Guelph
The situation — A home-care agency, Guelph, Ontario
A home-care agency in Guelph, Ontario had been reassessed for $120,000. 10 days were left on the objection deadline. The reassessment rested on company vehicles used personally with no logbook and no taxable benefit reported.
What we did for A home-care agency, Guelph, Ontario
We filed the objection inside the deadline with a complete submission rather than a placeholder. Alongside it, we moved the account to the correct remitter frequency and caught up the arrears. We filed a taxpayer relief request that cancelled the bulk of the penalty.
The result — A home-care agency, Guelph, Ontario
The appeals officer allowed the objection in full. $120,000 was reversed and the account returned to a nil balance.
