Canada Tax Guides 2026

Overview – Canadian tax in 2026

Canada’s tax system is administered by the Canada Revenue Agency (CRA). For 2026, indexation adjustments apply to brackets and credits. This guide covers the essentials: GST/HST for businesses and consumers, federal income tax brackets, common deductions, and smart filing tips.

GST/HST – what you need to know

The Goods and Services Tax (GST) is a 5% federal tax. Some provinces have harmonized sales tax (HST) combining provincial and federal portions. Others apply separate provincial sales tax (PST).

2026 GST/HST rates by province

Who must register for GST/HST?

If you are a sole proprietor, partnership, or corporation that makes taxable sales (other than zero‑rated) over $30,000 in any four consecutive calendar quarters, you must register. Under the $30,000 small‑supplier threshold, registration is voluntary but can allow input tax credits.

Filing and remitting

GST/HST returns are usually filed annually, quarterly, or monthly depending on revenue. The CRA offers online filing via GST/HST NETFILE. Keep all receipts to claim input tax credits (ITCs) for GST/HST paid on business expenses.

2026 federal income tax brackets

For 2026, federal brackets are indexed by 2.5% (estimated). The basic personal amount is approx. $15,000. Below are the projected brackets for 2026:
