Understanding GST/HST is essential for every Canadian business owner. Getting it wrong can lead to penalties, interest charges, and cash flow problems. Here’s everything you need to know.
What is GST/HST? — GST (Goods and Services Tax) is a 5% federal tax on most goods and services sold in Canada. HST (Harmonized Sales Tax) combines the federal GST with provincial sales tax in participating provinces. In Ontario, HST is 13%.
When Must You Register? — You must register for GST/HST when your revenue exceeds $30,000 in any single calendar quarter or over four consecutive calendar quarters. Even below this threshold, voluntary registration can be beneficial as it allows you to claim Input Tax Credits.
Input Tax Credits (ITCs) — When you pay GST/HST on business purchases, you can claim those amounts back as Input Tax Credits. This is one of the key benefits of GST/HST registration. Keep all receipts and ensure they include the supplier’s GST/HST number.
Filing Frequency — Depending on your annual revenue, you’ll file GST/HST returns annually, quarterly, or monthly. Annual filers with revenue under $1.5 million file once per year. Quarterly filing is required for revenue between $1.5 million and $6 million.
Quick Method of Accounting — Small businesses with revenue under $400,000 can use the Quick Method, which simplifies calculations by applying a flat remittance rate to revenue instead of tracking every ITC. This often results in keeping more GST/HST collected.
Common Mistakes — The most frequent GST/HST errors include: not registering on time, failing to charge tax on taxable supplies, not filing returns by the deadline, and not claiming all eligible ITCs.
Penalties for Non-Compliance — Late filing penalties start at 1% of the amount owing plus 0.25% for each month late, up to 12 months. Interest is also charged on outstanding balances. The CRA takes GST/HST compliance very seriously.
