Newfoundland & Labrador Sales Tax Rate History
Newfoundland and Labrador was one of the three original provinces to adopt the Harmonized Sales Tax in April 1997, alongside Nova Scotia and New Brunswick. NL's pre-HST provincial sales tax was among the highest in Canada at 12%. This page documents every major rate milestone from the 1991 dual-tax era through the 2016 increase to 15%, and the reverse-calculation formulas that apply in each period.

Historical Context
1991: GST and Newfoundland Retail Sales Tax
When the federal Goods and Services Tax replaced the Manufacturers' Sales Tax on January 1, 1991, Newfoundland and Labrador retained its 12% Retail Sales Tax alongside the new 7% GST. The provincial RST was one of the highest provincial sales tax rates in Canada at the time. The combined nominal burden of 7% GST plus 12% RST was 19% on most taxable goods, administered through two separate authorities: the CRA for GST and the Newfoundland Department of Finance for RST.
1997: Original HST Adoption
On April 1, 1997, Newfoundland and Labrador became one of the three original HST provinces alongside Nova Scotia and New Brunswick. The harmonization set the provincial component of HST at 8% — considerably lower than the pre-existing 12% RST — combined with the 7% federal GST for a total of 15%. For most goods, the effective tax burden decreased substantially from the pre-HST combined rate of approximately 19%, as the provincial component dropped from 12% to 8%. The provincial RST was abolished and all administration transferred to the Canada Revenue Agency on a single combined return.
2006–2008: Federal GST Reductions
The federal GST component within HST was reduced by one percentage point on July 1, 2006 (total HST from 15% to 14%) and again on January 1, 2008 (from 14% to 13%). Newfoundland and Labrador's provincial component remained at 8% throughout; only the federal portion changed. These reductions applied uniformly across all HST provinces.
2016: Provincial Component Increase
On July 1, 2016, Newfoundland and Labrador raised the provincial component of HST from 8% to 10%, bringing the total rate from 13% to 15%. The increase was announced in the province's April 2016 budget under Premier Dwight Ball's Liberal government as a response to a severe fiscal deficit driven in part by falling oil revenues. Newfoundland and Labrador and New Brunswick increased their HST rates simultaneously on the same effective date — both moving from 13% to 15%.
Reverse Calculation by Era
When working backwards from a gross total to extract the pre-tax amount, the divisor depends on which rate was in effect at the time of the transaction. For pre-1997 transactions, note that the combined rate was approximately 19%, and the GST and RST were separate taxes with different exemption schedules.
| Era | Tax Structure | Reverse Formula |
|---|---|---|
| 1991–1997 | GST 7% + PST 12% | Pre-tax = Total ÷ 1.19 |
| Apr 1997–Jun 2006 | HST 15% | Pre-tax = Total ÷ 1.15 |
| Jul 2006–Dec 2007 | HST 14% | Pre-tax = Total ÷ 1.14 |
| Jan 2008–Jun 2016 | HST 13% | Pre-tax = Total ÷ 1.13 |
| Jul 2016–present | HST 15% | Pre-tax = Total ÷ 1.15 |
For current transactions, divide by 1.15 to isolate the net pre-tax amount. When auditing pre-1997 transactions, use 1.19 as an approximation — but note that the 12% RST and 7% GST were separate taxes with different exemption rules, so precise historical filings may require separating the two components individually rather than applying a single combined divisor.
