PEI HST: 15% rate, heating rebate and CRA filing

PEI's HST transition in April 2013 — and what it replaced

Prior to 1 April 2013, PEI ran a separate 10% Provincial Sales Tax (PST) under the Revenue Tax Act in parallel with the federal 5% GST. The two were cascaded: GST applied first to the pre-tax price, then PST applied to the GST-inclusive amount — so a $100 sale produced $5 GST and then $10.50 PST (10% on $105), for a $15.50 total tax on $100 of base. Effective combined rate was 15.5%, not the 15% headline.

The 2013 HST switch eliminated the cascade and harmonised the provincial 10% portion with the federal 5% into a single 15% rate applied to the pre-tax price — saving customers 0.5 percentage points on the effective rate, and saving businesses the administrative overhead of two parallel tax administrations. Pre-2013 PST-period transactions still have residual reporting obligations for the few audits that reach back that far, but the modern framework is entirely HST-driven.

PEI's heating point-of-sale rebate

PEI offers one major point-of-sale rebate that reflects the province's cold winters and heavy reliance on heating fuel: the 10% provincial portion is rebated on residential heating oil, residential electricity for home heating, and propane for home heating. Sellers charge HST on the federal 5% portion only and claim the rebate back via Line 111 of the GST/HST return. The rebate doesn't extend to commercial heating, motor vehicle fuel, or industrial energy use.

Practical mechanics for utilities and fuel-oil dealers: tag residential heating accounts in the customer master; HelloBooks applies the rebate logic on those accounts automatically and runs commercial accounts at the full 15% rate. The split matters for utilities serving mixed residential/commercial portfolios where the rebate is consequential to the customer's bill.

Filing cadence and the small-province context

Standard CRA-assigned frequencies: annual under CAD 1.5M, quarterly $1.5M-6M, monthly above $6M. Returns via GST/HST NETFILE by end of next month for monthly/quarterly filers, 3 months post year-end for annual filers. PEI's small size (under 170,000 population) means most businesses are sole proprietors or small partnerships at the annual-filing tier — but the federal threshold still applies, so a successful tourism-season business in Cavendish that crosses the $30K small-supplier threshold mid-year must register and file monthly returns even when off-season volume drops below threshold.
