Moving from the US to Nova Scotia: What Changes on Your Taxes, and What Follows You

Halifax is the Atlantic city Americans move to: Dalhousie and the health sciences, the naval and shipbuilding sector, ocean technology, and a growing software scene. Nova Scotia is a high-rate province, with a 21% top provincial bracket for a combined top marginal rate near 54%, and a 14% HST after the 2025 cut. The US filings follow you regardless of province.

Key takeaways

• No arrival tax. Property is deemed acquired at fair market value when you become a Canadian resident; US basis is unchanged.
• NS's combined top rate is about 54%. The foreign tax credit generally eliminates US tax on NS-taxed income.
• 14% HST on most purchases.
• MSI (Medical Services Insurance) coverage generally begins on the first day of the third month after arrival.
• Nova Scotia charges a Non-Resident Deed Transfer Tax on residential purchases by buyers who are not residents; becoming a resident before you buy avoids it.

Becoming a Nova Scotia resident

Residency starts when you establish residential ties. From that date Canada taxes worldwide income, and under section 128.1 of the Income Tax Act most property is deemed acquired at fair market value on arrival. Your US basis stays where it was.

NS specifics:

• Provincial tax. Brackets top out at 21%. Combined top rate about 54%. Brackets are not fully indexed, so real bracket creep is a feature.
• Sales tax. 14% HST.
• MSI. Register on arrival; coverage generally begins the first day of the third month after you establish residence.
• Property. Municipal deed transfer tax of up to 1.5% (Halifax charges 1.5%), plus the provincial Non-Resident Deed Transfer Tax of 5% if the buyer is not a Nova Scotia resident at purchase and does not move in within six months.

What follows you from the US

• Annual 1040 with Form 1116 foreign tax credits; NS's rates cover the US liability on employment income with excess credits to carry forward.
• FBAR and Form 8938 on Canadian accounts above thresholds.
• PFIC. Canadian mutual funds and Canadian-listed ETFs each require Form 8621. Hold US-listed ETFs instead.
• TFSA. Taxable in the US and potentially a foreign trust. Skip it.
• RRSP. Canadian deduction, US deferral under the treaty.
• Roth IRA. Article XVIII(7) election on the first Canadian return; no contributions after arrival.
• 401(k) and IRA. Stay in the US; taxable in Canada on withdrawal with a foreign tax credit; section 60(j) rollover available.
• T1135 once non-Canadian property exceeds $100,000 CAD in cost (arrival year exempt).

Who moves to Nova Scotia

Academics and clinicians into Dalhousie and the health authority, naval and shipbuilding engineers, ocean technology researchers, software developers, and Americans with Maritime families or retirement plans on the South Shore.

Worked example

An American physician moves from Boston to Halifax on August 1 with $350,000 in a US brokerage account (US basis $220,000), $400,000 in a 403(b), and a Roth IRA of $90,000. She buys a house in October.

• Arrival. Brokerage deemed acquired at $350,000 for Canadian purposes; US basis stays at $220,000.
• 403(b). Left in place; taxable in Canada on withdrawal.
• Roth. Article XVIII(7) election on the first T1; no further contributions.
• House. Bought as a Nova Scotia resident, so no Non-Resident Deed Transfer Tax; Halifax's 1.5% municipal deed transfer tax applies.
• NS. Salary taxed at combined rates reaching 54%; foreign tax credit eliminates the US tax on it. MSI from the first day of the third month.
• Reporting. FBAR and Form 8938 on new Canadian accounts; no TFSA, no Canadian mutual funds.

Practitioner note

The Nova Scotia sequencing question is the house. Buy before you are a resident and the 5% Non-Resident Deed Transfer Tax applies unless you move in within six months; buy after and it does not. On a $900,000 Halifax home that is $45,000. We put the closing date after the residency date whenever the client's timeline allows.
