How to Close a Sole Proprietorship in Canada

What closing a sole proprietorship actually means

To close a sole proprietorship in Canada, you stop operating, cancel your business registration with the registry that issued it, close any CRA program accounts such as GST/HST or payroll, report your final year on Form T2125 with your personal tax return, and keep your business records for the retention period the CRA requires. Because a sole proprietorship is not a separate legal entity, there is no dissolution filing equivalent to what a corporation completes.

A sole proprietorship is not separate from you — you and the business are the same taxpayer. Closing it is therefore a sequence of administrative steps rather than a formal wind-up. Name registration happens at the provincial, territorial or federal level, while tax accounts sit with the Canada Revenue Agency (CRA), so closing a sole proprietorship usually means dealing with more than one government office. As of the current tax year, most jurisdictions allow you to cancel a business name registration online, but the process and any final fees differ. Confirm the current steps with the registry that issued your registration.

Step 1: Settle your affairs before you cancel anything

Cancelling too early can leave loose ends — unpaid suppliers, GST/HST you collected but never remitted, or payroll you have not finished. Before you cancel your registration:

• Issue and collect outstanding invoices, and clear customer deposits.
• Pay or make arrangements for suppliers, leases, loans and credit accounts.
• Finish and remit any GST/HST you collected (GST/HST invoicing requirements in Canada).
• If you had employees, complete final pay, source deductions and T4 slips (can a sole proprietorship have employees).
• Reconcile your books so your final return reflects reality (bookkeeping for sole proprietors).

Step 2: Cancel your business registration

To cancel business registration for a sole proprietorship, contact the provincial, territorial or federal registry that issued it. Depending on where you operate, that could be a provincial registry, a territorial one, or the federal Business Number name registration handled through the CRA for certain businesses. No two registries work identically, so check your registry's cancellation page, download any confirmation, and keep it with your records as proof of the closing date.

Not every sole proprietor is registered at all. If you only ever operated under your own legal name and never registered a business name, there may be nothing to cancel (do I need to register a sole proprietorship). You should also cancel or transfer anything registration-related that sits outside the registry: municipal business licences, zoning permits, professional licences, and health, liquor or contractor permits. Those are issued by separate bodies and are not closed automatically.

Step 3: Close your CRA program accounts

Once your registration is cancelled, you can ask the CRA to close the program accounts tied to your Business Number (BN). The CRA generally expects a final return for each account before it will close it, so file first and close second. Closing an account does not erase a balance owing, and you can request closures through CRA My Business Account, by phone, or in writing.

Step 4: File your final income tax return

Sole proprietorship income and expenses are reported on Form T2125, Statement of Business or Professional Activities, filed with your personal T1 return. Your final year is the year you ceased operating, and it should include business income up to the closing date, plus recaptured depreciation or a terminal loss on assets you disposed of. If you sold or transferred business assets — inventory, equipment, or a vehicle used partly for business — report those dispositions correctly. Final-year adjustments are easy to overlook, so consider working with an accountant for that return.

Step 5: Wind down contracts, employees and accounts

Closing a business in Canada also means tidying up obligations that have nothing to do with the registry. Review leases, service contracts, insurance policies, merchant accounts, business phone, domain and email, and any subscriptions billed to the business. If you employed staff, issue a Record of Employment through Service Canada whenever there is an interruption of earnings, and keep payroll records with your other books. If you are closing because you are incorporating instead, the timing of the wind-up matters — see sole proprietorship vs corporation.

Records, deadlines and common mistakes

The CRA requires business records to be kept for a set retention period after the end of the last tax year they relate to, and that clock keeps running after you stop operating (business records retention in Canada). Keep ledgers, invoices, receipts, GST/HST returns, payroll records and your final T1 and T2125 together, stored somewhere you can access later.

• Assuming a cancelled registration cancels your tax debts.
• Stopping operations without filing a final GST/HST return or payroll remittance.
• Forgetting municipal licences, permits, domain names and software subscriptions.
• Discarding records too soon after closing.
• Not telling the CRA that you stopped operating, so notices and filing expectations continue.

This is general information, not legal or tax advice. Processes, fees and filing rules vary by province, territory and business type, so confirm the current requirements on the CRA website and with your provincial or territorial registry before you cancel anything.
