Moving from the US to Nova Scotia: What Changes on Your Taxes

Nova Scotia has one of the heaviest tax loads in Canada: a top provincial rate of 21%, stacked on federal tax for a combined marginal rate above 54%, plus 15% HST on nearly everything you buy. Americans still take the corridor anyway, drawn by Irving Shipbuilding’s decades-long federal shipbuilding contract, CFB Halifax, the Dalhousie and QEII healthcare cluster, and a small but real ocean-technology sector. This page covers what’s specific to landing in Nova Scotia; the federal cross-border mechanics (1040 filing, FBAR, FATCA, RRSP treatment) are the same regardless of which province you land in.

Why are Americans moving to Nova Scotia?

Halifax’s economy runs on a small set of large, durable employers, which is unusual for a city its size and part of the appeal. Irving Shipbuilding anchors the National Shipbuilding Strategy, a program worth more than $60 billion over its life, and it hires engineers, tradespeople, and project managers steadily enough that it pulls talent directly from US defense and marine contractors.

• CFB Halifax, the largest military base in Canada, creates a parallel corridor for defence contractors and support staff, often overlapping with people who already have security-cleared backgrounds from US Navy or defense-industry work.
• Healthcare is the other pillar. The QEII Health Sciences Centre and Dalhousie University form a teaching-hospital cluster that recruits physicians, nurses, and researchers directly from the US, particularly from New England where licensing and practice patterns are closer to Nova Scotia’s than they are to, say, California’s.
• Layered on top is a smaller but genuine ocean-technology sector, built around the Centre for Ocean Ventures and Entrepreneurship and a cluster of subsea and marine engineering firms, plus a Halifax tech scene that’s grown enough to support its own recruiting pipeline.
• The strongest pull, in either direction, runs through the long-standing Halifax-to-Boston relationship: shared industries, shared universities, and a direct flight that makes the move feel less like emigrating and more like relocating within the same region.

How do Nova Scotia’s tax rates compare to home?

Nova Scotia’s five provincial brackets top out at 21% on income above roughly $154,650 (2026, confirmed annually against the Nova Scotia Department of Finance schedule). Add federal tax and the combined marginal rate on the top bracket clears 54%, among the highest anywhere in Canada, matched only by a handful of other provinces.

Jurisdiction	Top rate	Threshold	Sales/consumption tax
Nova Scotia	21% (about 54%+ combined with federal)	~$154,650	15% HST
Massachusetts	5% flat (9% surtax above $1M)	$1,053,750 for the surtax	6.25%
Maine	7.15%	$61,600	5.5%
New Hampshire	0% on wages	n/a	0%

The gap is large at every income level, not just the top bracket. A US move that looks like a modest raise on paper can still land at a materially higher marginal rate once Nova Scotia’s brackets and HST are both in the picture, especially for anyone coming from Massachusetts’s flat 5% or New Hampshire’s 0% on wages.

How does HST work compared to US sales tax?

Nova Scotia charges HST (Harmonized Sales Tax) at 15%, a single blended rate combining the federal GST portion with the provincial component. There’s no separate PST to track and no exemption patchwork to learn province by province; one rate applies to most goods and services, administered entirely by the CRA. That’s simpler to administer than a US state-plus-local system, but it’s also higher than nearly every US sales tax rate, and unlike US sales tax it applies to most services as well as goods.

• For a household budgeting the move, the practical effect is that everyday costs run higher than the sticker-price comparison to Halifax rents and groceries suggests, once HST is added at the register.

When does MSI coverage start?

MSI (Medical Services Insurance) is Nova Scotia’s public health plan, and it isn’t immediate. New residents typically wait through the balance of their arrival month plus two full months before coverage begins, a gap of up to three months depending on when in the month you land. During that window you need private insurance; an employer relocation package sometimes bridges it, but confirm that in writing before you rely on it.

• Apply for your Nova Scotia Health Card as soon as you have a permanent address, since the waiting period is calculated from your application and residency date, not from when coverage happens to kick in.
• If you’re coming from a US employer plan, check whether COBRA continuation coverage can bridge the gap; it’s often cheaper than a short-term private Canadian policy and easier to arrange before you leave.

What happens to my 401(k), IRA, and Roth IRA?

Your US retirement accounts don’t close or convert when you move; they keep growing under US rules, but Canada’s treatment of each account differs and matters for reporting.

• 401(k) and traditional IRA. These are treaty-deferred: Canada doesn’t tax the growth as it accrues, matching US deferral, and you report the accounts on your Canadian return without current tax. Withdrawals are taxed by both countries when they happen, with a foreign tax credit coordinating the two.
• Roth IRA. A Roth doesn’t get treaty protection automatically. It stays tax-free in Canada only if you file the one-time Article XVIII election with your first Canadian return. Miss that election and Canada can tax the Roth’s growth as it happens, which defeats the entire point of holding it.
• FBAR and FATCA never stop. Every account above the filing thresholds gets reported on FBAR and, separately, on Form 8938 under FATCA. Moving to Halifax doesn’t end US reporting on US or Canadian accounts; it just adds a Canadian return alongside the 1040 you keep filing every year you hold US citizenship.

What does housing cost in Halifax?

Halifax’s housing costs have climbed sharply over the past several years, and while the absolute dollar figures still sit below Toronto or Vancouver, the comparison that actually matters is cost against Nova Scotia incomes, which run lower than in Canada’s largest cities. A salary that covers a comfortable Halifax mortgage today buys noticeably less than the same salary would have five years ago, and newcomers used to Boston-area pricing sometimes assume Halifax is automatically cheap; it’s cheaper in absolute terms, not necessarily cheaper relative to what the local job market pays.

• Budget the move with Nova Scotia’s after-tax income, not the gross US salary you’re leaving behind, since the 21% top provincial rate and 15% HST both bite before a single housing dollar is spent.

What should I do next?

Model both returns before the move: the final US-year return and the first Canadian return, so the FTC position and the NS bracket exposure are known quantities rather than a surprise at filing time. Pre-move planning is the window to decide on Roth elections, HSA liquidation, and timing income around the move date. Apply for your MSI card the day you have a permanent Halifax address, and line up private or COBRA coverage for the gap before it opens, not after.
