HST/GST ITC Checker

Check if your business purchase qualifies for an input tax credit and estimate how much HST you can recover.

How the ITC calculation works

An input tax credit (ITC) lets GST/HST-registered businesses recover the HST paid on eligible business purchases. The recoverable amount is: purchase amount × business-use % × 13% (Ontario HST rate). You must have a valid HST invoice from a registered supplier, and your own sales must not be fully tax-exempt.
