GST/HST Small Business Deregistration: When and How to Exit

If your small business revenue has dropped below the GST/HST registration threshold, or you're planning to wind down operations, you may wonder whether you can deregister. The answer depends on your current sales level and whether you meet CRA eligibility rules. In most cases, if your revenue falls below $30,000 over four consecutive quarters, this CRA rule may apply to you for voluntary deregistration. However, deregistration isn't automatic, and there are important tax and cash flow consequences to understand before making the move. Not every business owner who wants to deregister can do so immediately. The CRA has specific rules about when deregistration is allowed. You may be eligible to deregister if: - Your revenue has fallen below $30,000 over four consecutive calendar quarters - You're winding down your business and expect sales to remain below $30,000 - You're discontinuing commercial activities entirely - You meet the Small Suppliers Exemption criteria (revenue under $30,000 annually, though this rule may apply to you if you elected to register voluntarily) If you're a large business that voluntarily registered for GST/HST even though you weren't required to, you still need CRA approval to deregister.

Frequently Asked Questions

Can I deregister from GST/HST if my revenue drops below $30,000?

You may be eligible to deregister if your revenue has fallen below $30,000 over four consecutive calendar quarters and you meet CRA eligibility criteria. However, you cannot simply cancel registration yourself; you must request approval from the CRA, which will review your situation and confirm the deregistration date.

What happens to GST/HST on my unsold inventory when I deregister?

When you deregister, the CRA may consider your inventory as a deemed supply, meaning you could owe GST/HST on the fair market value of unsold goods. This tax liability must be calculated and included in your final GST/HST return before deregistration is approved.

Will I lose input tax credits after deregistration?

Yes. Once deregistered, you can no longer claim input tax credits on business expenses, even if you pay GST/HST on supplies or equipment. This is one of the biggest cash flow impacts of deregistration, especially for businesses with significant ongoing expenses.

Do I need to file a final GST/HST return when I deregister?

Yes. Before the CRA approves deregistration, you must file a final return covering the period up to your deregistration date. This return accounts for all tax owing or refunds due and ensures all outstanding obligations are settled.

Can I re-register for GST/HST after deregistering if my business grows again?

Yes. If your revenue exceeds $30,000 over four consecutive quarters after deregistering, you may be required to re-register. You can also request re-registration voluntarily at any time if you believe it benefits your business.

Steps

  1. Gather your revenue records: Collect your sales revenue for the past four consecutive calendar quarters to demonstrate that your revenue has fallen below or will stay below $30,000. Accurate records are essential because the CRA will verify this information before approving deregistration.
  2. Calculate your inventory value: Determine the fair market value of any unsold inventory or stock on hand at the time you plan to deregister. This value will be subject to GST/HST under the deemed supply rule and must be included in your final return.
  3. Request deregistration from the CRA: Contact the CRA's GST/HST enquiries line or submit a written request through CRA My Account. Provide your GST/HST account number, revenue documentation, and evidence that you meet the eligibility criteria for deregistration.
  4. File your final GST/HST return: Complete and submit a final GST/HST return covering the period up to your requested deregistration date. Include any tax owing on inventory, outstanding credits, and adjustments needed to close out your account.
  5. Receive CRA approval and confirmation: Wait for the CRA to review your request and approve deregistration. They will provide a letter confirming your deregistration date (usually the first day of a calendar month) and any final amounts owing or refundable.
  6. Stop charging GST/HST after the deregistration date: On the deregistration date, cease charging GST/HST to your customers and update your invoicing templates and systems. Keep records of the deregistration approval from the CRA for your files.
