CactusComply Government: one configurable system for permits, returns, refunds and inspections
A working prototype prepared in response to a Government of Yukon request for information on tax administration modernization. It runs tobacco, insurance premium and fuel oil tax in one platform, on synthetic data, with an inspections app that works offline.
Sized to a real program
The prototype is seeded to the scope in the RFI. Every permit holder, return and payment in it is synthetic.
3
Tax programs in one platform: tobacco, insurance premium and fuel oil
628
Active synthetic permits, matching the count stated in the RFI
8
Permit types, from tobacco wholesalers to inter-provincial carriers and insurers
32
Requirements traced from the RFI to a screen and the code behind it
What it does
Permits and returns
Apply, approve and renew permits, then file monthly, quarterly and annual returns. Tax is calculated from effective-dated rates and validated before submission.
Amendments that keep history
An amendment is a new version linked to the original, with a field-level comparison, recalculated tax, and a balance due or refund. Nothing is overwritten.
Offline inspections
An installable web app works with the network off: checklists, product counts, photos and notes. On reconnect it syncs and shows conflicts instead of silently overwriting them.
Refunds with separation of duties
Refunds and penalties move from assessment to approval against signing limits. The person who assesses cannot approve. Digital signatures are simulated in the prototype.
Reconciliation and reporting
Auto-match a simulated deposit feed, with an exceptions queue for the rest. KPI dashboards, a report builder, and illustrative agency report layouts round it out.
Tamper-evident audit trail
A hash-chained log you can verify on screen, anomaly flags for officers, and an access-request export that redacts third-party information.
Who it helps
TAX OFFICERS
Work from one queue
Permits, returns, inspections and refunds in one place, in place of manual mirroring between systems.
DIRECTORS
Review and sign
Approval routing by role and amount, with a record of who decided what and when.
ADMINISTRATORS
Change without code
Rates, filing rules and even a new levy are configuration. The levy in the demo is hypothetical.
TAXPAYERS
File online
A secure portal with multi-factor sign-in for filing, amendments, messages and payment status.
What is real, and what is simulated
The workflows, tax calculations, offline sync, audit chain and REST status API run in the prototype. Published tobacco, fuel and insurance premium tax rates were checked against yukon.ca on October 12, 2026; penalty amounts and signing limits are labelled placeholders.
Staff single sign-on, digital signatures, the invoicing API and the deposit feed are simulated. Agency report layouts are illustrative. The proposed production design hosts all data in Canada on Microsoft Azure. The commodity-tax configuration has no government deployment yet. It builds on CactusComply, our tax platform, which the Arizona Department of Revenue has approved for e-file and which has been live since April 22, 2026.

CactusComply Government is an independent prototype by Osonwanne Group LLC, prepared in response to Government of Yukon RFI-2026-9-5562, a market-research request that does not select a vendor. All data is synthetic. It is not a Government of Yukon system, and it is not affiliated with or endorsed by the Government of Yukon or any agency.
