Business accounting in Atlantic Canada starts with HST: 15% in New Brunswick, Newfoundland and Labrador and Prince Edward Island, and 14% in Nova Scotia since April 1, 2025. One registration covers the federal and provincial parts, and you file one return. For 2026 the provincial small business rates run from 1% to 2.5%.
How much HST do you charge down east?
The CRA lists Nova Scotia at 14% after the provincial part fell from 10% to 9%. The CRA’s page on which rate to charge says the same. Our rate table, built from the CRA’s rate information, has the other three at 15%. Here’s a $1,000 sale in each, from the GST/HST calculator.
| Province | HST rate | Tax on $1,000 | Invoice total |
|---|---|---|---|
| New Brunswick | 15% | $150 | $1,150 |
| Newfoundland and Labrador | 15% | $150 | $1,150 |
| Prince Edward Island | 15% | $150 | $1,150 |
| Nova Scotia | 14% | $140 | $1,140 |
The Nova Scotia cut has transitional rules. Anything invoiced or paid before the change may still carry 15%, and real property depends on when ownership and possession both pass. The CRA points to two notices on this, GST/HST Notices 342 and 343. If you still have invoices dated around April 1, 2025 in dispute, read them before you amend anything.
Working backwards from a receipt? The reverse HST calculator pulls the tax out of a total.
The percentages look small until the invoices get bigger. On a $5,000 job, a Halifax contractor charges $700 of HST while a Moncton one charges $750. The extra $50 isn’t the contractor’s to keep. It goes to the CRA, so the books should never count it as revenue.
What corporate tax rates apply for a small company?
The CRA lists all four provinces on its corporation tax rates page, which we checked in November 2026. Here is what it shows. The lower rate is the provincial small business rate and the higher rate is the general rate.
| Province | Lower rate | Higher rate | Small business limit | Start date on the CRA page |
|---|---|---|---|---|
| New Brunswick | 2.5% | 14% | $500,000 | Not stated |
| Nova Scotia | 1.5% | 14% | $700,000 | Not stated |
| Newfoundland and Labrador | 2% | 15% | $500,000 | January 1, 2026 (down from 2.5%) |
| Prince Edward Island | 1% | 15% | $600,000 | July 1, 2025 (general rate down from 16%, limit up from $500,000) |
The federal rate for a Canadian-controlled private corporation is 9% on income under the federal limit and 15% on the rest. The full picture is on our small business tax rates page and the corporation tax rates page.
What does $300,000 of profit cost in tax?
Take a Canadian-controlled private corporation with $300,000 of active business income. That is under every provincial limit above, so the small business rates apply. Federal tax is $27,000 at 9% in every province. The provincial slice and the total differ.
| Province | Provincial tax | Federal tax | Total |
|---|---|---|---|
| Prince Edward Island (1%) | $3,000 | $27,000 | $30,000 |
| Nova Scotia (1.5%) | $4,500 | $27,000 | $31,500 |
| Newfoundland and Labrador (2%) | $6,000 | $27,000 | $33,000 |
| New Brunswick (2.5%) | $7,500 | $27,000 | $34,500 |
That is a $4,500 spread between the cheapest and the dearest on identical profit. It is a reason to read a province’s budget before you decide where to incorporate, not a reason to move a head office. The corporate tax calculator uses the same method. It leaves out credits, and associated companies and passive income only enter through optional boxes, so a real bill can differ.
How does business accounting in Atlantic Canada handle payroll and filing?
Payroll is federal in all four provinces. You withhold income tax, CPP and EI and remit to the CRA. The payroll remittance calculator shows what that looks like. For one employee on $3,000 every two weeks in Nova Scotia, the total to send is about $1,104 a pay period, including your own share. Provincial income tax is the only part that changes with the province.
The CRA says most GST/HST registrants must file electronically, through your CRA account or the GST/HST NETFILE form. If you are not registered yet, our page on getting an HST account explains when you need one. Get your online account working before your first due date, not on it.
How do seasonal businesses cope with HST?
Fishing, tourism and farming income arrives in lumps, but HST is due on the reporting period you’ve registered for. Picture Lena, who runs a boat tour on the Newfoundland coast and sells $60,000 of tours between June and September. At 15% she has collected $9,000 of HST on those sales. The money feels like cash in the bank in August and stops being hers on the due date.
Put a slice of each deposit aside as you go, in a separate account if you can. A good summer can leave you short on the day the return is due, and nobody sends a polite reminder for the winter months.
What mistakes do Atlantic businesses make most?
Using the wrong Nova Scotia rate on old invoices is the obvious one. Next is assuming a cheap provincial rate means a cheap bill, when the limit and the federal tax change the picture. Then there’s the records rule. The CRA wants books kept in Canada for six years after the year they cover, in a format it can read. A cloud tool whose servers sit abroad is worth a question to the provider. The Nova Scotia GST and HST page covers the transition rules, and accounting software for GST/HST explains how to test a rate table.
Where did we check this?
In November 2026 we read three CRA pages: the corporation tax rates page (last modified October 21, 2026), the page on which GST/HST rate to charge (Nova Scotia at 14% from April 1, 2025, with Notices 342 and 343 on the transition) and the CRA guidance on keeping records. The 15% HST rate for New Brunswick, Newfoundland and Labrador and Prince Edward Island comes from our rate table, which is built from CRA rate information. This site is independent and is not connected to any government. We did not confirm provincial payroll levies or workers’ compensation rates, so none are quoted.
Frequently asked questions
What is the HST rate in Atlantic Canada?
It is 15% in New Brunswick, Newfoundland and Labrador and Prince Edward Island. Nova Scotia charges 14% because its provincial part fell from 10% to 9% on April 1, 2025. On a $1,000 sale that is $150 of tax in three provinces and $140 in Nova Scotia.
Which Atlantic province has the lowest small business tax rate?
On the CRA corporation tax rates page, Prince Edward Island shows 1%, Nova Scotia 1.5%, Newfoundland and Labrador 2% (from January 1, 2026) and New Brunswick 2.5%. Add the federal 9% for a Canadian-controlled private corporation to get the combined rate on income under the limits.
Do I file separate GST and HST returns in Atlantic Canada?
No. All four provinces are HST provinces, so one registration and one return cover the federal and provincial parts. You report the tax collected on sales and claim input tax credits for what you paid. Most registrants must file electronically, through My Business Account or GST/HST NETFILE.
Is payroll different in Atlantic Canada?
The withholding system is the CRA’s in every province outside Quebec. You withhold income tax, CPP and EI and remit to the CRA. Only the provincial income tax part of the deduction changes with the province. Provincial levies and workers’ compensation are separate and we did not verify them.
How long must an Atlantic business keep its books?
The CRA says to keep records for six years from the end of the last tax year they cover, in Canada and in a form it can read. A cloud tool whose servers sit abroad is worth a question to the provider. Electronic records must stay readable for the whole period.
