Closing a sole proprietorship in Canada is simpler than closing a corporation, but it involves several distinct steps across different government levels. Missing any of them can create ongoing compliance obligations or unexpected tax bills. Here is the complete process.
Step 1: Decide on Your Closing Date
Choose a specific date on which business operations cease. This date determines:
- Your final GST/HST reporting period
- The fiscal year end for your final T2125 (business income and expenses)
- When to issue final invoices and collect outstanding receivables
It is usually simplest to choose December 31 as your closing date so it aligns with your personal tax year and simplifies the final T1 filing.
Step 2: Complete All Final Business Obligations
- Invoice and collect all outstanding receivables before closing
- Pay all outstanding business debts and obligations (suppliers, contractors)
- Complete any in-progress client work or formally terminate contracts
- Notify clients and suppliers of your closure
Step 3: Cancel Provincial Business Name Registration
If you registered a business name provincially, you should cancel (dissolve) the registration:
- Ontario: File a dissolution through the Ontario Business Registry (ontario.ca/businessregistry). There is no fee to dissolve a sole proprietorship registration in Ontario.
- British Columbia: File a Statement of Dissolution through BC Registries (bcregistry.gov.bc.ca). No fee.
- Alberta: File a Cancellation of Trade Name through an authorized registry agent (~$30–$50).
- Quebec: File a declaration of closure at the Registraire des entreprises (REQ). No fee for simple closures.
If you simply let your registration lapse (expire without renewing), it will eventually be removed from the registry, but you may receive renewal notices or fines for failure to update the registry in some provinces.
Step 4: File Your Final GST/HST Return and Close the Account
If you are registered for GST/HST:
- File your final GST/HST return covering the period up to your closing date — include any GST/HST collected that has not yet been remitted
- When you have a zero balance, contact the CRA to close (deregister) your GST/HST account, or do it through My Business Account online
- The CRA will send a confirmation of deregistration by mail
- If you had significant business assets, the CRA treats the deemed disposition of those assets as a taxable supply at market value — discuss this with your accountant
Keep your GST/HST records for 6 years after the last return is filed, even after deregistration.
Step 5: File Your Final Personal Tax Return
In the year you close, file your T1 personal return as usual, including Schedule T2125 for the final partial or full year of business income. Report:
- All business income received up to the closing date
- All allowable business expenses incurred up to the closing date
- Any disposal of business assets (equipment, vehicle) — capital gains or recaptured depreciation (CCA) may apply
- Home office expenses proportional to the period the business was operating
Pay any balance owing by April 30 of the following year. File by June 15 if you or your spouse were self-employed during the year (even if you closed the business partway through).
Step 6: Close Your Business Bank Account
After all final payments are cleared and the GST/HST account is closed, close your business bank account. Make sure all outstanding cheques or pre-authorized payments have cleared before closing.
Step 7: Keep Records
The CRA requires you to keep business records for 6 years after the last tax year they relate to. Even after closing your business, retain:
- All invoices (incoming and outgoing)
- Bank statements
- Expense receipts
- GST/HST returns and records
- T2125 worksheets and supporting documentation
Frequently Asked Questions
Do I owe any closing fees to the government for closing a sole proprietorship?
Generally no. Cancelling a provincial business name registration is free (or very low cost) in most provinces. Closing CRA accounts is free. The main costs are any outstanding tax balances due, your accountant’s fee for the final return, and any bank fees for closing accounts.
What if I want to reopen the same business later?
You can re-register the same or a similar business name later. There is no restriction on reopening. You would simply go through the same provincial registration and CRA registration process again. If you retained your records, the historical business context (for tax purposes) carries forward to the extent the new operation is a continuation of the old one.
Do I need to notify clients formally?
From a legal standpoint, no — there is no requirement to formally notify every client. However, for good business practice, notify regular clients with enough advance notice to find alternatives, complete any outstanding work, and settle all accounts. Abrupt closure without notice can damage professional relationships and create dispute risk over outstanding deliverables.
