Mr. Speaker, in processing parliamentary returns, the government applies the Privacy Act and respects the principles set out in the Access to Information Act. In responding to questions relating to the harmonized sales tax, HST, it also respects its commitments under the comprehensive integrated tax coordination agreements, CITCAs, with HST provinces.
With regard to the harmonized sales tax, it is a value-added sales tax imposed under federal legislation and administered by the Canada Revenue Agency, CRA, and the Canada Border Services Agency, CBSA. The tax has a federal portion that is equivalent to the goods and services tax, GST, with a rate of 5 percent, and a provincial portion, with a rate that varies by province. Currently, the combined federal-provincial rates are 13 percent in Ontario and 15 percent in Newfoundland and Labrador, Nova Scotia, New Brunswick, and Prince Edward Island. The tax base of the HST, i.e., what is subject to the tax, is essentially that of the GST. The operation of the HST is governed by CITCAs between Canada and each HST province. Under the CITCAs, provinces are provided with certain flexibilities. Specifically, provinces are allowed to increase or decrease the rate of the provincial portion of the HST; provide provincial rebates to consumers at the point of sale, subject to an overall limit of 5 percent of the estimated GST base in a province and certain other conditions; set the rates applicable to the provincial component of the HST for rebates provided to public service bodies; and set the rate and thresholds of provincial new housing rebates, based on the general structure of the federal rebate.
Under the HST, businesses deal with only one tax administration and remit HST using the same return that they use for the GST. When filing their returns, businesses are not required to track the HST by the province in which transactions occur or to differentiate the provincial portion from the federal portion of the tax. All GST and HST is remitted as a single amount. In lieu of collecting such detailed information from businesses, the revenues attributable to the provincial portion of the HST are paid to provinces using a revenue-estimation formula known as the revenue allocation framework, RAF. That framework is set out in annex A of the CITCAs.
With regard to the revenue allocation framework, the RAF makes use of economic data from Statistics Canada and administrative data from the CRA and the CBSA to determine taxable consumption in Canada and the share of that consumption attributable to each participant in the RAF, i.e., the HST provinces and the federal government. More specifically, taxable consumption is estimated through five bases: consumer expenditure, approximately 63%; public sector bodies, approximately 12%; housing, approximately 17%; business, approximately 2%; and financial institutions, approximately 6%.
There are two fundamental components in the determination of the amount of sales tax revenue that each HST province will receive: the size of the GST/HST revenue pool and the provincial shares. The GST/HST revenue pool is the sum of all GST/HST assessed by the CRA and the CBSA nationally, net of input tax credits and applicable rebates. The provincial shares are determined by measuring the revenue potential of the total of the five bases in each jurisdiction, relative to the total revenue potential of the GST/HST.
The GST/HST revenue pool is currently on the order of $71 billion per year.
With regard to the revenue estimation process, annual provincial revenue entitlements are the product of the assessed GST/HST, meaning the revenue pool, and each province’s share of the common tax base. Payments for a given entitlement year are first estimated in December prior to the start of the entitlement year. They are recalculated each December for five years, i.e., those five years are open. In the June that follows the fifth year, i.e., five and half years after the end of the calendar year in question, provincial payments are finalized and cannot be re-estimated. For example, in December 2016, the first estimate for 2017 was provided; in June of 2023, the final estimate for 2017 will be calculated and the year will close. Because revenue entitlements are estimated and since data comes in over several years, the amount of revenue to which an HST province is entitled for a particular year can change. As a result, a province may receive more revenue or may be required to repay revenue that it has already received, as revenue entitlements for open years are recalculated each December. In the event that a total repayment associated with prior years is greater than 7% of the estimated current entitlement, e.g., the 2017 entitlement year currently, provinces have the option of repaying the entire amount over three years.
