CPA-led GST/HST registration, return preparation, ITC reconciliation, and audit support for businesses in Toronto and across Canada.
GST/HST compliance is not a single filing. It is a continuous obligation — registration at the right threshold, correct application of place of supply rules, ITC documentation for every business purchase, and timely remittance on the correct reporting frequency.
Errors in GST/HST compliance — missed registration, incorrect ITC claims, or late remittances — result in penalties, interest, and CRA audit exposure. TYM prepares GST/HST returns with the documentation standard that CRA review requires.
Failure to register when taxable revenues exceed $30,000 results in liability for all GST/HST that should have been collected from the date the threshold was crossed — plus interest and penalties. The CRA can assess the unregistered business for the full amount of tax that should have been collected.
ITCs claimed without proper documentation — supplier name, GST/HST registration number, date, amount, and description — are disallowed on audit. The CRA routinely requests ITC documentation during GST/HST audits. Disallowed ITCs result in additional tax, interest, and potential gross negligence penalties.
Businesses operating in multiple provinces must apply the correct HST rate based on the place of supply rules. Applying the wrong rate — or failing to collect HST on supplies made in participating provinces — results in a liability for the uncollected tax, interest, and penalties.
Self-employed individuals who have crossed the $30,000 registration threshold, or who wish to register voluntarily to recover ITCs on business expenses.
Corporations with GST/HST obligations — including businesses with multiple revenue streams, real property transactions, or cross-border supplies that require specific place of supply analysis.
Businesses that export goods or services, import goods or services, or supply digital services to Canadian consumers — each category has specific GST/HST treatment that must be applied correctly.
Businesses that have not registered when required, have not filed returns, or have claimed ITCs without adequate documentation — voluntary disclosure is available before the CRA initiates contact.
GST/HST on real property transactions — new construction, substantial renovations, commercial property sales — involves specific rules and elections that differ from the treatment of most other supplies.
Law firms, accounting firms, consulting firms, and other professional services businesses with GST/HST obligations, including the interaction between GST/HST and provincial sales taxes in non-harmonized provinces.
TYM assesses the registration threshold, the correct reporting frequency, and whether the Quick Method election is beneficial. Registration is completed with the CRA, and the reporting period is set to match the business's cash flow and compliance capacity.
GST/HST returns are prepared with a full reconciliation of GST/HST collected on sales and ITCs available on business purchases. Each ITC is supported by documentation that meets the CRA's requirements for the amount claimed.
For businesses with multi-province operations or cross-border transactions, TYM applies the place of supply rules to determine the correct rate and treatment for each supply. Zero-rating provisions and non-resident registration requirements are addressed as part of the compliance engagement.
If the CRA selects the GST/HST account for audit or review, TYM manages the response with the return support file and ITC documentation. For businesses with prior period non-compliance, voluntary disclosure is available before the CRA initiates contact.
