Does the Harmonized Sales Tax (HST) apply if the contract was awarded before July 1, 2010?
HST may apply depending on the percentage of work performed prior to July 1, 2010. If at least 90% of the work is completed prior to July 1, 2010, then HST does not apply. However, if less than 90% of the work is completed, HST applies to the portion of work done after July 1, 2010. For example, if a contract valued at $50,000 is awarded on January 1, 2010 and 60% of the work is completed before July 1, 2010, then HST would apply to 40% of the value of the contract or $20,000. You will need to amend your contract to remove the GST applicable to the portion of services received after July 1, 2010 and include the value of HST.
