How to Close a GST/HST Account in Canada
Close a GST/HST account in Canada: when you can deregister, the one-year rule for small suppliers, Form RC145, the final return and two reporting periods, and the tax on property still held at closing.
How to close a business in Canada the right way: wind-down order, closing CRA payroll and GST/HST accounts, final T1 and T2 returns, the TX19 clearance certificate, and dissolution fees for federal, Ontario, BC, and Alberta — plus what actually happens if you just stop filing.
Applies in: across Canada
Closing a business in Canada is not one form — it is a sequence, and the order matters. Close things in the wrong order and you create work for yourself: CRA treats an undissolved corporation as still alive (returns owed every year, even at zero income), and a closed bank account before the final GST/HST remittance means hunting down how to pay it. Get the order right and the whole thing is five steps: wind down, close the CRA accounts, file the final returns, dissolve or cancel the registrations, then shut the money off.
This guide uses the current government fees and the official process pages, with the worked specifics for Ontario, British Columbia, and Alberta plus the federal track. Figures that come with a caveat say so.
Before touching a government form, settle the real world. CRA and the registries both expect the business to have no outstanding liabilities at the end: a federal corporation can only be dissolved once it has no property and no liabilities, and every province's dissolution process assumes debts are paid first. Practically this means:
CRA has a dedicated page for this — "Closing CRA program accounts" (canada.ca) — and it walks through each account separately.
Payroll account (RP). Before closing, you must remit all outstanding payroll source deductions, calculate pension adjustments for former employees under a registered pension plan or deferred profit-sharing plan, file the final payroll information returns, and give T4 and T4A slips to the employees. When the business stops operating: remit any CPP, EI, and income tax owing within 7 days of the day the business stops, and file the T4 Summary within 30 days of the business ending.
GST/HST account (RT). CRA treats account closure as the expected companion to business closure — it is presented as the standard step, not an optional one. You notify CRA and give the reason; the cancellation date is the day your business closes. Close it through My Business Account or Represent a Client, by mailing Form RC145 (Request to Close Business Number Program Accounts, Part B) to your tax centre within 6 months of signing it, or by phone at 1-800-959-5525. Then file the final GST/HST return and remit anything owing. Two details catch people out on the final return: CRA deems you to have sold all non-capital property held for consumption, use, or supply in the commercial activity — you remit GST/HST on its fair market value just before closing — and all capital property used in the commercial activity is deemed collected at its basic tax content, which generally means repaying some or all of the input tax credits you previously claimed. You may need to file two returns: one for the period ending the day before closure, and one for the stub period ending the day of closure (only if there is tax to remit in that stub).
Corporation income tax account (RC). The order here runs the other way: dissolve the corporation at the registry first, file the final T2, then consult Form RC145 and send a copy of the articles of dissolution to CRA. This is the account-closure step people skip — and CRA's warning is blunt: otherwise "the CRA considers that the corporation still exists and it will have to file a return even if there is no tax payable."
Sole proprietors report business income on the T2125 business schedule of the personal T1 — there is no separate business return to close, so the "final return" is your regular T1 for the last year of operation. Filing deadlines: June 15 for self-employed filers, with any balance owing still due April 30. (CRA's own filing-due-dates page sets both dates for the 2025 return.)
Corporations file a final T2 within six months of the end of the tax year — the same deadline as every other corporate return, per the T2 Corporation Income Tax Guide (T4012). Late filing draws penalties, and the final return is the one that has to balance: all income, all payroll, all GST/HST accounted for.
The clearance certificate (Form TX19). Recommended, not required — but worth understanding what it actually buys. The TX19 protects the legal representative (the director, liquidator, or executor) from personal liability for the corporation's unpaid tax if company property is distributed before CRA's assessments are done. CRA's archived circular IC82-6 puts it this way: for a corporate dissolution, you "should" get a clearance certificate before distributing the property — and if you distribute without one, you are liable for the unpaid amounts (ITA s. 159(2)). Do not apply until all required returns are filed, the final notices of assessment are in hand, and all income taxes, CPP, EI, interest, and penalties are paid or secured. If the business had a GST/HST account, file Form GST352 with the TX19. For a corporation you will need a directors' or shareholders' resolution confirming the intent to dissolve and the dissolution date, the notice of assessment for the final T2, a statement of asset distributions to date plus the proposed distribution plan, and proof of legal-representative status.
Federally incorporated (Corporations Canada). The official dissolution guide lays out two paths, and both start from the same rule: the corporation can only be dissolved when it has no property and no liabilities. A bankrupt or insolvent corporation cannot voluntarily dissolve. The paths are: (1) liquidate first, then apply for a certificate of dissolution; or (2) file Form 19 – Statement of Intent to Dissolve first — the corporation must then stop carrying on business except to liquidate, notify its creditors, and publish notice in each province where it carries on activities — and once liquidation is complete, submit the articles of dissolution online. The fee, officially: no filing fee for either certificate (both the certificate of intent and the certificate of dissolution are free). If no shares were ever issued, a directors' resolution suffices instead of a shareholder special resolution.
Ontario. A sole proprietor or partnership cancels the master business licence through the Ontario Business Registry: log in, select the registration, and choose "cancel" under the "Make changes" tab — no fee to cancel a sole proprietorship. An Ontario corporation files Articles of Dissolution online through the Registry: you need the corporation name, the Ontario Corporation Number, and the effective date; the Ministry of Finance consent is forwarded automatically for online filings (no separate consent-letter step), and the fee is $25.00.
British Columbia. A BC company files Form 17 – Application for Voluntary Dissolution through Corporate Online; the company must be in good standing (annual reports current) before the registrar will issue the certificate of dissolution and publish the notice. The official BC Registry dissolution package lists the fee at $20.00 plus a $1.50 BC OnLine service fee; requesting a future effective date (up to 10 days ahead) adds $100. One caveat: that $20 figure comes from the Registry's official dissolution package — the gov.bc.ca fee schedule page for the standard Form 17 did not render a fee line, so treat the package figure as the one to verify at filing time.
Alberta. Corporations file dissolution through an authorized Alberta service provider (a registry agent): vote to dissolve, sell property and pay debts (or appoint a liquidator), complete the Articles of Dissolution, and bring the forms, ID, and fee payment to the agent. The official Registry Agent Product Catalogue lists the government fee for a certificate of dissolution at $0.00 — the registry agent adds their own service fee on top. (That catalogue is dated 2021; the agent will quote current fees when you file.)
Quebec. Quebec runs its own registry, the Registraire des entreprises du Quebec (REQ), and the route depends on the legal form. A sole proprietor files a declaration of radiation through the REQ online service in Mon Bureau (in French only), after submitting all required documents and collecting any refunds owed. A Quebec corporation's shareholders pass a special resolution to dissolve. If there is nothing to liquidate, the corporation files a declaration of dissolution with the REQ. If liquidation is required, it files a notice of liquidation followed by a notice of closure of liquidation. Once the documents are accepted, the Registraire issues a certificate of dissolution, which is what ends the corporation's legal existence. The law requires a registered legal person that has decided to dissolve to file a declaration to that effect with the enterprise registrar without delay, and the directors must appoint a liquidator. The REQ filing closes the registration only. It does not close the tax accounts: the CRA closures and the Revenu Quebec GST/QST and payroll cancellations in Step 2 still have to be done separately.
Once the accounts and registrations are closed: close the business bank accounts, cancel the business credit cards, cancel insurance policies, deregister from municipal business licences, and cancel any extra-provincial registrations in other provinces. Then archive the books — CRA's assessing and audit powers do not end when the business does, and a clean paper trail is what makes a reassessment a non-event instead of a disaster.
This is the FAQ with the most wishful thinking around it, so here is what the official pages actually say. If you are required by law to file and do not, CRA may assess you estimated tax under subsection 152(7) of the Income Tax Act, estimating from your prior filings — plus late-filing and repeat late-filing penalties under section 162 when tax is owing, and interest. For a corporation, there is no "quietly going away": if you never dissolve and never notify CRA, the CRA treats the corporation as still existing and it owes a return every year even with no income. Being struck off the registry for non-compliance is not a clean close either — it is the registry acting against you, and it runs independently of what CRA is doing.
Directors carry personal exposure. Under the directors' liability rules, directors in office when the corporation failed to remit payroll source deductions or GST/HST are jointly and severally liable with the corporation for those amounts, plus penalties and interest, and CRA can assess a former director within two years of when they last served. The defence is due diligence — showing a reasonably prudent director would have acted the same way. And dissolution does not end this: the rules expressly cover corporations that have commenced dissolution proceedings or have already been dissolved. In plain terms: closing properly is cheaper than abandoning, and the cleanest $0 you will ever spend is the free federal dissolution certificate after the debts are paid.

Government fees only — the accountant's bill for the final T2 return is usually the bigger cost.
There is no single form for the whole shutdown — it is a sequence. Close your CRA accounts (GST/HST via My Business Account or [Form RC145](https://www.canada.ca/en/revenue-agency/services/forms-publications/forms/rc145.html), payroll after final remittances), file your final tax return (the [T2125](https://www.canada.ca/en/revenue-agency/services/forms-publications/forms/t2125.html) business schedule on your personal T1, due June 15 for self-employed with any balance owing due April 30), then cancel your Ontario master business licence by logging into the Ontario Business Registry, selecting your registration, and choosing 'cancel' under the 'Make changes' tab — there is no fee for the cancellation.
Less than most founders expect, but it varies by registry. Corporations Canada charges no filing fee for a federal certificate of dissolution. Ontario charges $25.00 for online Articles of Dissolution. British Columbia's official dissolution package lists $20.00 plus a $1.50 BC OnLine service fee ($100 extra if you request a future effective date). In Alberta, the government fee on the official Registry Agent Product Catalogue is $0.00 — but you file through an authorized registry agent who adds their own service fee. These are government fees only; accountant bills for the final T2 return are the bigger cost.
Yes. CRA's own closing-a-business guidance treats GST/HST account closure as the standard companion step to shutting down, not an optional extra: you notify CRA and give the reason, the cancellation date is the day your business closes, and you file a final GST/HST return and remit anything owing. Close it online through My Business Account or Represent a Client, by mailing [Form RC145](https://www.canada.ca/en/revenue-agency/services/forms-publications/forms/rc145.html) (Part B) to your tax centre within 6 months of signing it, or by phone at 1-800-959-5525.
CRA keeps assessing. Under subsection 152(7) of the Income Tax Act, CRA can assess estimated tax for a corporation or business that never filed, with late-filing and repeat late-filing penalties under section 162 if tax is owing, plus interest. If the corporation is never dissolved and CRA is never told, CRA treats it as still existing — it owes a return every year even with zero income. Walking away does not end the obligation; dissolving and filing the final returns does.
It is recommended, not legally required. The [TX19](https://www.canada.ca/en/revenue-agency/services/forms-publications/forms/tx19.html) clearance certificate protects the corporation's legal representative — the director, liquidator, or executor distributing the property — from personal liability for the corporation's unpaid tax amounts if assets are distributed before CRA finishes assessing. You apply only after all required returns are filed, the final assessments are in, and all taxes, CPP, EI, interest, and penalties are paid or secured. If the corporation had a GST/HST account, file [Form GST352](https://www.canada.ca/en/revenue-agency/services/forms-publications/forms/gst352.html) alongside the [TX19](https://www.canada.ca/en/revenue-agency/services/forms-publications/forms/tx19.html).
They can be. Under the Income Tax Act and the Excise Tax Act, directors in office when the corporation failed to remit payroll source deductions or GST/HST are jointly and severally liable with the corporation for those amounts, plus penalties and interest — and CRA can assess a former director within two years of when they last served. The defence is due diligence: showing a reasonably prudent director would have acted the same way. Dissolving the corporation does not block CRA from proving its claim — the directors' liability rules specifically cover corporations that have commenced dissolution or have already been dissolved.
A voluntary dissolution is something you file for — a deliberate, clean shutdown after paying debts and filing returns. Being struck off is what the registry does to you for non-compliance, such as failing to file annual returns for years. Struck-off corporations can sometimes be revived, but a strike-off is not a shortcut to a clean close: CRA's estimated assessments and directors' liability operate independently of what the corporate registry does.
Before CRA will close a payroll account, you must remit all outstanding source deductions, calculate pension adjustments for former employees under a registered pension or deferred profit-sharing plan, file the final payroll information returns, and hand T4 and T4A slips to the employees. When the business stops, remit any CPP, EI, and income tax owing within 7 days of the cessation day, and file the T4 Summary within 30 days of the business ending.
