The CRA HST number is essential for businesses in Canada to validate whether a supplier is properly registered for GST/HST.
Without confirming this number, your input tax credit claims may be denied, and you risk paying tax that cannot be recovered.
How to Confirm a CRA HST Number
The Canada Revenue Agency provides a free GST/HST Registry that allows businesses to confirm if a supplier is registered. You must confirm the CRA HST number before claiming any input tax credits.
Steps to confirm:
- Visit the CRA GST/HST Registry.
- Enter the first nine digits of the supplier’s GST/HST account number. Do not include letters.
- Provide the business name as listed on invoices or official documents.
- Enter the transaction date from the receipt, invoice, or contract.
- Review and print the search confirmation for your records.
If the number is valid, you can safely claim input tax credits. If the number is invalid, contact your supplier or call the CRA Business Enquiries line at 1-800-959-5525.
Information You Need Before Using the Registry
To search the CRA HST number, you must have:
- GST/HST account number: First nine digits only.
- Business name: The legal, operating, or trade name on the invoice.
- Transaction date: The date listed on the business document.
Suppliers are required to display their HST number on all receipts, invoices, contracts, or related documents for taxable goods and services of $100 or more.
If a supplier does not provide their HST number, you should request it directly. If they refuse, call CRA to verify.
What to Do After Confirming the CRA HST Number
Once confirmed, print the search results page as proof. This ensures that any GST/HST credits you claim can be supported during a CRA audit.
Remember:
- Input tax credits can only be claimed on transactions with registered suppliers.
- Keep documentation for your records in case of review.
When You Cannot Use the Online Registry
The CRA’s online registry cannot validate numbers used for QST purposes by selected listed financial institutions (SLFIs). For these cases, contact CRA’s Business Enquiries line directly.
For QST-only validations, use Revenu Québec’s verification tool.
