Moving from Canada to Arizona: A Flat 2.5%, the Snowbird Pipeline, and Low Property Tax

Arizona has been a Canadian snowbird destination for decades, and it has become a semiconductor, aerospace, and financial back-office hub in the last one. The tax picture is among the simplest in the US: a flat 2.5% state income tax, the lowest flat rate of any state that taxes income, no city income tax anywhere in the state, and property tax among the lowest in the country. The Canadian side carries the departure tax, and for retirees, the substantial presence test was probably met before the move.

Key takeaways

• Arizona's flat 2.5% income tax; no city income tax anywhere in the state.
• Arizona starts from federal AGI, so the treaty's RRSP deferral flows through.
• Sales tax runs about 8.6% in Phoenix, 8.05% in Scottsdale, 8.7% in Tucson.
• Property tax is near 0.6% effective.
• No estate tax. Snowbirds usually meet the substantial presence test before the move.

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.

Arizona's side

Flat 2.5% state income tax; no city income tax; sales tax (Arizona's transaction privilege tax) of about 8.6% in Phoenix, 8.05% in Scottsdale, and 8.7% in Tucson; property tax near 0.6% effective with an owner-occupied classification that caps annual increases; no estate tax. Arizona starts from federal AGI and taxes capital gains as ordinary income at 2.5%, with a 25% subtraction for long-term gains on assets acquired after 2011.

The RRSP

Federally deferred under Article XVIII of the treaty and deferred for Arizona 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 Arizona's 2.5%.

Who makes this move

Canadian retirees going permanent in Scottsdale, Mesa, and Tucson after years of wintering, Ontario and Quebec engineers to the Chandler and north Phoenix semiconductor fabs, Canadian aerospace engineers to Honeywell, Boeing Mesa, and Raytheon Tucson, and Canadian finance staff to the banks' Phoenix back offices.

Worked example

An Ontario couple leaves on September 30 with $250,000 of unrealized gain in a non-registered account, $900,000 in RRSPs, and a Toronto home sold in the departure year.

• Departure tax. $250,000 gain, $125,000 taxable, at about 53.5%: roughly $67,000.
• Home. Sold as a resident under the principal residence exemption.
• RRSP. No tax on departure; RRIF conversion and periodic withdrawals at 15% Canadian withholding; Arizona 2.5% on the US side.
• CPP/OAS. Taxable only in the US; no clawback.
• Scottsdale. Combined top rate about 39.5%. HST 13% becomes sales tax 8.05%. Property tax on a $700,000 home around $4,200.

Official sources

"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

Arizona retiree files are the ones where we most often find a client who met the substantial presence test two winters before the move. We count days for the prior three years before we set the departure date, because the answer changes which year the FBAR and the TFSA exposure began.
