Here are some of the key dates you should be aware of as you prepare for the Harmonized Sales Tax (HST).

June 18, 2009

October 14, 2009

  • Ontario released its transitional rules regarding property and services in Information Notice No. 3, General Transitional Rules for Ontario HST, available at ontario.ca/taxchange
  • Certain businesses and public service bodies may be required to self-assess the provincial component of the HST on consideration paid or payable after this date and before May 1, 2010 for property or services to be provided after June 2010. The Ontario component of the HST must be accounted for by the due date of their GST/HST return for the reporting period that includes July 1, 2010, if that return is due before November 2010.

May 1, 2010

June 30, 2010

  • All RST vendors will receive a final Retail Sales Tax (RST) return that ends on this date. Vendors whose normal reporting period ends after June 30, 2010 will be required to file a final RST return for the shortened period ending on this date. Final returns are due by July 23, 2010.

July 1, 2010

  • Implementation date of HST in Ontario. Suppliers of taxable goods and services in Ontario are generally required to charge, collect and remit HST.
  • RST will continue to apply to taxable insurance premiums and private sales of used vehicles.

October 31, 2010

  • All RST liabilities are to be reconciled no later than this date and any RST that is collected or becomes payable (for example, any tax still owing from customers) after June 2010 is to be reported on a supplemental return to be filed by the business owner on or before the 23rd day of the following month. Additional information about supplemental returns will be provided in the near future.
