Registered Education Savings Plan (RESP)

Your marginal tax rate is the rate on your next dollar of income, not on your income as a whole. Federally for 2026 that is 14%, 20.5%, 26%, 29% or 33% depending on the bracket you have reached, and your province's rate stacks on top, so an Ontario earner in the 26% federal band adds the Ontario rate for their own band. The two sets of thresholds rarely line up, so add the two rates together.

Most enquiries are settled without a phone call in My Account, My Business Account or Represent a Client, where assessments, balances, slips and CRA mail all sit. When you need a person, use the enquiries line for your programme from the contact page on canada.ca, and have your social insurance or business number plus a figure from a recent return ready for identity checks. Written enquiries go to the tax centre named on your notice of assessment.

Tax exempt describes an amount or a transaction that tax does not apply to at all, which is different from a deduction or credit that merely reduces tax. Common examples are supplies that are exempt or zero-rated for GST/HST, investment income earned inside a TFSA, and specific receipts Parliament has excluded from income. Registered charities and non-profits can be exempt from income tax while still carrying filing duties. Exemption is never automatic; the rule must fit your facts.

Federal tax is the share of income tax that goes to the federal government, charged on taxable income in graduated brackets that are the same everywhere in Canada. Your total bill is that federal amount plus your province or territory's own tax, less the credits you claim. Payroll deductions shown on a T4 cover both layers. Quebec residents receive a refundable abatement of their federal tax because Quebec opted out of certain federal-provincial programs and funds them itself; separately, Quebec also collects its provincial tax through its own return.
