HST Audit Recovery
We review up to four years of your GST/HST filings for missed input tax credits, overpaid tax, and unclaimed rebates. The review is free. We're only paid a percentage of what we recover.
Most businesses leave HST unclaimed.
Input tax credits get missed all the time: HST paid at the border that never made it into the books, invoices coded without tax, capital purchases expensed with no credit claimed, rebates nobody knew to file. CRA won't tell you what you forgot to claim, and once the time limit passes, that money is gone for good.
What we look for
Missed Input Tax Credits
Vendor bills and card purchases recorded without their HST, subscriptions from registered suppliers, and expenses split incorrectly between business and personal use.
GST/HST Paid on Imports
Tax paid to CBSA at the border is usually recoverable, but it often sits in a customs broker invoice and never reaches the GST/HST return.
Capital Property & Vehicles
Equipment, leasehold improvements, and vehicles. The ITC on a passenger vehicle bought in 2026 is capped at the tax on $39,000, and it's often missed entirely.
Tax Charged in Error
Suppliers who charged HST on exempt or zero-rated supplies. We recover it through a supplier credit note or a CRA rebate application, which generally must be filed within two years.
Public Service Bodies' Rebates
Charities and qualifying nonprofits in Ontario can recover 50% of the federal part and 82% of the provincial part of HST paid. Many never claim it.
How it works

Our fee is the agreed percentage of what's recovered. If we don't find anything, you owe nothing.
HST Audit Recovery FAQs
The review is free. If we find recoverable HST, our fee is an agreed percentage of the amount recovered, set out in writing before we start. If we don't find anything, you don't pay anything.
