What Happens If You Don’t Charge GST/HST When You Should?

Failing to charge GST/HST when required can have serious financial and legal consequences for your business. Whether it’s an honest mistake or a misunderstanding of tax rules, ignoring your GST/HST obligations can lead to unexpected liabilities. This guide will walk you through what happens if you don’t charge GST/HST, how to correct the mistake, and how to avoid future issues.

1. Consequences of Not Charging GST/HST

If your business surpasses the $30,000 small supplier threshold but fails to register and charge GST/HST, you may face the following.

  • Unpaid Tax Liability: The Canada Revenue Agency (CRA) may require you to remit the GST/HST you should have collected—even if you didn’t charge your customers.
  • Penalties and Interest: The CRA can impose penalties and interest on unremitted taxes, increasing your financial burden.
  • Audits and Scrutiny: Consistently failing to charge GST/HST can trigger an audit, leading to further compliance checks and potential fines.

2. How to Correct a GST/HST Charging Mistake

If you realize you haven’t been charging GST/HST when you should have, here’s what you can do.

  • Register for GST/HST Immediately: If your revenue exceeds $30,000, apply for a business number and register for GST/HST to become compliant.
  • Voluntary Disclosure Program (VDP): If you’ve failed to charge GST/HST in previous years, you can apply to the CRA’s VDP to disclose your mistake and possibly reduce penalties.
  • Reassess Past Transactions: Identify past sales where GST/HST should have been applied and determine if customers can be billed retroactively.
  • Remit Owed Taxes: If you owe GST/HST from past sales, submit the amount to the CRA as soon as possible to minimize penalties and interest.

3. How to Avoid GST/HST Compliance Issues

To prevent future mistakes and ensure compliance, consider the following.

  • Understand Taxable Sales: Determine whether your products or services are taxable, zero-rated, or exempt.
  • Charge the Correct Rate: Apply the correct GST/HST rate based on your customer’s location.
  • Keep Accurate Records: Maintain detailed invoices, receipts, and accounting records to track tax obligations.
  • Use Accounting Software: Automate tax calculations with software like QuickBooks or Xero to minimize human error.
  • Consult a Tax Professional: If you’re unsure about your GST/HST obligations, seek advice from an accountant to avoid costly mistakes.

Final Thoughts

Not charging GST/HST when required can create financial and legal risks for your business. The best approach is to stay informed, register on time, and maintain proper records. If you’ve already made a mistake, act quickly to correct it and ensure compliance moving forward. Being proactive will save you from potential penalties and financial strain.
