HST in Nova Scotia
The rate went down, and half the internet never noticed
Nova Scotia is the one province where an old chart will actively cost you a customer conversation. The number moved, and a lot of the pages you would find first still have not caught up.
Nova Scotia charges 14% HST. The province cut the provincial share on 1 April 2025, which brought the total down from 15% where it had sat since 2010. There is no separate provincial sales tax to add. Use the rate that applied on the date of the invoice, not today's rate, when you bill old work.
Rates on this page are read from the same table our GST/HST calculator uses, checked against the Canada Revenue Agency. It is a rate page, not tax advice.
A cut that most rate charts slept through
HST in Nova Scotia is a single 14% harmonized tax covering both the federal and the provincial share. One rate, one line, nothing added on top. It is the lowest HST rate in Atlantic Canada after the April 2025 cut.
The province lowered its own portion of the harmonized rate. Nothing else about how you invoice moved. Same taxable supplies, same single line, same rules about place of supply.
What did change is the reliability of anything you look up. A rate chart from before that date is now wrong for Nova Scotia and right for everywhere else, which is exactly the kind of half-wrong that survives a quick glance.
- 01Cut the provincial share of the HST

- 03Left the federal share exactly where it was
- 04Did not introduce a separate provincial tax
- 05Did not change what the tax applies to
Why the Maritimes stopped being one number
For years a contractor working across the region could carry one rate in their head. That stopped in April 2025.
- Nova Scotia and New Brunswick matched
- One number covered most Atlantic work
- A rate written on the van was good enough
- A stale chart was still accurate
- Nova Scotia sits below its neighbours
- Crossing the border changes the invoice
- The rate has to come off the job address
- A stale chart is a wrong invoice
Four questions that decide the rate you charge
Run these in order before you write the number on a quote. Most rate mistakes are a wrong answer to the first one.
- 01
Where was the work actually done?
The place of supply sets the rate, not where your business is registered.
- 02
Goods, or work on a building?
Delivered goods and work on real property follow different rules.
- 03
Are you registered yet?
Under the small-supplier threshold you do not charge GST or HST at all.
- 04
Does a separate provincial tax apply?
Four provinces charge one alongside the 5% GST, on the same pre-tax amount.
What do you do about an invoice from before the change?
Use the rate that was in force on the date of the invoice. That is the rule, and it is worth saying plainly because the instinct is to reach for the current number.
If you are chasing an old unpaid job, the tax on it stays what it was. Reissuing at today's rate would leave you having collected one figure and declared another, which is a reconciliation nobody enjoys explaining.
The same applies to a credit note against old work. Match the original. This is one of the few places in Canadian sales tax where the calendar does real work, and it is the reason both the calculator and the invoice builder keep the historical table around instead of only the current one.
A two minute check on your own paperwork
Find an invoice from spring 2025
Look at what rate you actually used either side of 1 April. That is where a stale figure would have crept in.
Check where the number came from
If it was typed by hand or copied off a chart, it is worth a second look. If it came from a table that updates, it is fine.
Look at any job that crossed a border
A Nova Scotia outfit working in New Brunswick now charges a different number than it does at home.
Fix the source, not the invoice
Changing one invoice fixes one invoice. Changing where the rate comes from fixes every job after it.

The rate follows the job. If the work crosses a border, so does the number you charge.
Nova Scotia HST, answered
Nova Scotia charges 14% HST. That one rate covers the federal and the provincial share together, so nothing gets added on top. It went down from 15% on 1 April 2025 when the province cut its portion.
Because the cut is recent and a lot of rate charts are copied rather than checked. Anything published before April 2025 will show the old number, and plenty of pages written since have simply reused it. Check the date on any chart before you trust it.
The one that applied on the invoice date, not the one that applies now. If the work was billed before 1 April 2025 it carries the old rate. Reissuing an old invoice at today's rate would understate the tax you already collected.
No. Nova Scotia is an HST province, so the provincial share already sits inside the single rate. There is nothing separate to calculate and nothing extra to put on the invoice.
Once your taxable sales pass $30,000 over four straight calendar quarters. Below that, registering is your choice, and it is often worth it because you can then claim back the tax you paid on tools and materials.
New Brunswick's, because the rate belongs to the place the work was done. The two provinces no longer match, so a job over that border is a different number on the invoice even though both are HST provinces.
Because the number in your head was right until April 2025. StrikeHoney reads the rate from a table that moved when the province did, applies it by province, and keeps the tax report. That is the whole reason not to type a rate in by hand.
What to remember
Nova Scotia is straightforward to invoice and easy to get wrong, and the reason is timing rather than complexity. The rate is 14% today and it was higher until 1 April 2025. Bill against the date the work was done. If you copied a rate off a chart at any point in the last couple of years, it is worth checking which number you actually put on those invoices.
