Moving from Canada to Connecticut: Graduated Rates, the NYC Commute, and the Fairfield County Corridor

Connecticut is where a large share of 'moving to New York' Canadians actually live: Stamford's hedge funds and Greenwich's family offices, Hartford's insurers, Yale and the New Haven biotech cluster, and the Fairfield County commuter towns that feed Manhattan. The tax picture is a graduated state income tax topping out at 6.99%, high property taxes, and a commuter problem: Connecticut has no reciprocity with New York, so a Fairfield County resident who works in Manhattan pays New York first and claims a Connecticut credit.

Key takeaways

• Connecticut's graduated income tax runs 2% to 6.99%.
• No city income tax.
• Sales tax is 6.35% statewide with no local additions.
• Property tax is high, near 1.8% to 2% effective.
• Connecticut's estate tax exemption matches the federal exclusion. No reciprocity with New York for commuters.

The Canadian departure

Departure tax applies to non-registered investments, private company shares, crypto, and foreign property at fair market value on the day you leave. Canadian real estate, RRSPs, TFSAs, and pensions are excluded. Report on Form T1243, list holdings on Form T1161 if the total exceeds $25,000, and post security under Form T1244 to defer tax on illiquid assets. The rate is your province's: on a $300,000 unrealized gain, roughly $72,000 from Alberta and $80,000 from Ontario, Quebec, or BC. Provincial health coverage ends around your departure date; confirm the exact date with your plan and arrange US coverage to start the same month.

US federal side

Dual-status return in the arrival year, FBAR on Canadian accounts above $10,000 aggregate, Form 8938 above thresholds, and the RRSP treaty deferral federally. The TFSA loses its tax-free status the day you become a US person; close it before crossing. Equity compensation vesting after the move is split by working days between Canada and the US.

Connecticut's side

Graduated income tax from 2% to 6.99%, with a recapture provision that phases out lower brackets for high earners; no city income tax; 6.35% sales tax with no local additions; property tax near 1.8% to 2% effective, among the highest in the US; estate tax with an exemption tied to the federal exclusion. Connecticut starts from federal AGI. A resident who works in New York pays New York non-resident tax and claims a Connecticut credit for it; the net effect is roughly New York's rate.

The RRSP

Federally deferred under Article XVIII of the treaty and deferred for Connecticut because the state starts from federal AGI. Withdrawals face 25% Canadian withholding on lump sums, 15% on periodic RRIF payments within the treaty limit, a US foreign tax credit federally, and Connecticut's graduated rates, with a partial pension exemption available at lower incomes.

Who makes this move

Bay Street finance professionals to Stamford's hedge funds and Greenwich's family offices, Canadian insurance staff to Hartford's insurers, Canadian biotech researchers to Yale and the New Haven cluster, and Canadians working in Manhattan who choose Fairfield County for space and schools.

Worked example

A Toronto hedge fund analyst moves to Stamford on June 30 with $300,000 of unrealized gain in a non-registered account, $600,000 in an RRSP, deferred compensation vesting over three years, and a Toronto condo sold in the departure year.

• Departure tax. $300,000 gain, $150,000 taxable, at about 53.5%: roughly $80,000.
• Condo. Sold as a resident under the principal residence exemption.
• Deferred comp. Split by working days; Connecticut taxes its share.
• RRSP. No tax on departure; federal and Connecticut deferral.
• Stamford. Combined top rate about 44% for a Stamford-based job. HST 13% becomes sales tax 6.35%. Property tax on a $1.2 million home around $22,000.

"When you leave Canada, you are considered to have sold certain types of property (even if you have not sold them) at their fair market value (FMV) and to have immediately reacquired them for the same amount. This is called a deemed disposition and you may have to report a capital gain (also known as departure tax)." — Canada Revenue Agency, Leaving Canada (emigrants), https://www.canada.ca/en/revenue-agency/services/tax/international-non-residents/individuals-leaving-entering-canada-non-residents/leaving-canada-emigrants.html

"You will be considered a United States resident for tax purposes if you meet the substantial presence test for the calendar year. To meet this test, you must be physically present in the United States (U.S.) on at least: 31 days during the current year, and 183 days during the 3-year period that includes the current year and the 2 years immediately before that." — Internal Revenue Service, Substantial Presence Test, https://www.irs.gov/individuals/international-taxpayers/substantial-presence-test

Practitioner note

The Connecticut decision is the commute. A Greenwich resident working in Manhattan pays New York's rate on wages and gets a Connecticut credit; the same person working in Stamford pays Connecticut's 6.99%. We run both before the client picks between the two.
