Input Tax Credit (ITC)

GST/HST

An input tax credit is the GST/HST a registered business pays on its purchases, which it claims back so that it only remits tax on the value it adds.

GST/HST is a value-added tax, so businesses do not bear the tax on their inputs. When you buy supplies, equipment or services for your business, the GST/HST you pay is recoverable as an input tax credit, netted against the tax you collected on sales. You remit only the difference.

To claim ITCs you must be registered, the expense must be for commercial activity, and you must hold proper documentation showing the tax. Common errors include claiming the full ITC on expenses that are only partly commercial, or on the 50% non-deductible portion of meals. Missed ITCs can generally be claimed for up to four years.

Example

You buy a $2,000 laptop plus $260 HST for your business. You claim the $260 as an input tax credit on your HST return, reducing what you owe the CRA dollar for dollar, so the laptop effectively costs you $2,000.

The questions Canadians actually search on this topic, answered plainly. Browse every question in the Canadian tax answers directory.

Yes, the CRA does telephone people, usually about a balance owing, a missing return, an audit or to verify information, and calls can come from many different numbers, so caller ID proves nothing either way. A real agent never demands payment by gift card, cryptocurrency or e-transfer, never threatens immediate arrest or deportation, and never asks for a password. If a call feels wrong, hang up, check your balance and mail in My Account, then call back using a number from canada.ca.

Canada uses a progressive system, so only the income falling inside a bracket is taxed at that bracket's rate. Moving into a higher bracket never raises the tax on the income below it. You face a federal set of brackets plus a provincial or territorial set, and both are indexed most years. Credits, starting with the basic personal amount, then reduce the calculated tax. Look up the brackets for the specific tax year before planning around them.

A ratepayer is someone who pays municipal rates, meaning property taxes and local utility charges, on property they own or occupy. The municipality sets a rate against assessed value, bills the ratepayer, and funds local services from what it collects; ratepayer associations speak for owners in an area. Property tax is municipal and quite separate from income tax, though on a rental or business property it is generally deductible against that income.

Personal income tax is the tax an individual pays on income from all sources: employment and self-employment earnings, pensions, investment income and the taxable portion of capital gains. Canada applies graduated federal rates with a provincial or territorial layer on top, reduced by credits such as the basic personal amount. Residents are taxed on worldwide income, non-residents only on certain Canadian-source income. You report it on a T1 return each year, and employers withhold tax as you are paid.
