Moving from Canada to New Mexico: Graduated Rates, Gross Receipts Tax, and the National Labs Corridor

Los Alamos and Sandia National Laboratories, Intel's Rio Rancho fab, Albuquerque's film industry, and the state's universities draw Canadian scientists and engineers. New Mexico's tax picture is a graduated income tax topping out at 5.9%, a gross receipts tax that functions like a sales tax but also applies to services, low property tax, and no estate tax. National lab roles typically require US citizenship or a green card.

Key takeaways

• New Mexico's graduated income tax runs 1.5% to 5.9% under the brackets restructured for 2025. No city income tax.
• The gross receipts tax runs about 7.6% to 8.3% in Albuquerque and Santa Fe and applies to services as well as goods.
• Property tax is near 0.8% effective.
• No estate tax.
• New Mexico starts from federal AGI and exempts Social Security for most taxpayers. National lab roles usually require a green card or citizenship.

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.

New Mexico's side

Graduated income tax from 1.5% to 5.9%; no city income tax; gross receipts tax of about 7.6% in Albuquerque and 8.3% in Santa Fe, applied to most goods and services and typically passed through to consumers; property tax near 0.8% effective with a 3% annual cap on residential valuation increases; no estate tax. New Mexico starts from federal AGI, exempts Social Security for taxpayers under an income threshold, and allows a deduction for a portion of capital gains.

The RRSP

Federally deferred under Article XVIII of the treaty and deferred for New Mexico 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 New Mexico's graduated rates.

Who makes this move

Canadian physicists, engineers, and computer scientists to Los Alamos and Sandia National Laboratories and their contractors, Canadian semiconductor engineers to Intel Rio Rancho, Canadian film crews to Albuquerque and Santa Fe productions, and Canadian academics to the University of New Mexico and New Mexico State.

Worked example

An Ottawa physicist moves to Los Alamos on August 31 with $180,000 of unrealized gain in a non-registered account, $450,000 in an RRSP, and a Kanata home sold in the departure year.

• Departure tax. $180,000 gain, $90,000 taxable, at about 53.5%: roughly $48,000.
• Home. Sold as a resident under the principal residence exemption.
• RRSP. No tax on departure; federal and New Mexico deferral.
• Los Alamos. Combined top rate about 42.9%. HST 13% becomes gross receipts tax about 7.3%. Property tax on a $600,000 home around $4,800.

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

National lab roles require a security clearance, which requires citizenship or a green card, and the green card's issue date becomes the US residency start. We coordinate the Canadian departure date with it. Consultants should note that New Mexico's gross receipts tax applies to their service revenue, not just to goods.
