CRA Audit

HST combines the 5% federal GST with a provincial component in five participating provinces. For 2026 the combined rates are 13% in Ontario, 15% in New Brunswick, Newfoundland and Labrador, and Prince Edward Island, and 14% in Nova Scotia since 1 April 2025. Elsewhere you charge the 5% GST alone, or GST plus a separate provincial tax. The rate follows the province of supply, not where your business sits.

A tax return is the annual filing that reports your income, deductions and credits to the CRA so the final tax for the year can be settled. Payers withhold tax during the year and the return reconciles that against what you actually owe, producing either a refund or a balance to pay. For 2025 returns filed in 2026, refunds usually arrive in about two weeks for an online return, while a paper return runs on a considerably longer standard because it is handled manually.

EI benefits are taxable income. Service Canada withholds income tax before each payment reaches you, and the total benefits plus the tax withheld appear on your T4E for the year. That withholding follows a basic calculation rather than your full marginal rate, so people who also worked during the year often end up with a balance owing at filing. Asking Service Canada to withhold more, or setting money aside yourself, avoids a surprise. Higher-income claimants can also have to repay part of their regular benefits through the return.

Federal income tax is the share of income tax that goes to the federal government, calculated on taxable income using federal brackets and then reduced by federal credits. Your province or territory levies its own income tax on the same income, which is why a paycheque outside Quebec shows one blended deduction rather than two. Employers estimate both when withholding. For your own figure, read the federal tax line on your assessed T1 rather than a rate table.
