Moving from Canada to Oklahoma: A 4.5% Top Rate, High Sales Tax, and the Energy and Aerospace Corridor

Oklahoma City and Tulsa are energy cities with growing aerospace and healthcare sectors: Tinker Air Force Base, American Airlines' Tulsa maintenance base, and the state's oil and gas operators recruit Alberta and Saskatchewan engineers directly. Oklahoma's tax picture is a graduated income tax topping out at 4.5% for 2026, after 2025 legislation cut the rate from 4.75% and collapsed six brackets into three, high combined sales tax, low property tax, and no estate tax.

Key takeaways

• Oklahoma's graduated income tax tops out at 4.5% for 2026, down from 4.75%, with further trigger-based cuts scheduled. No city income tax.
• Combined sales tax runs about 8.6% in Oklahoma City and 8.5% in Tulsa.
• Property tax is near 0.9% effective with a homestead exemption and a 3% annual cap on assessment increases for homesteads.
• No estate tax.
• Oklahoma starts from federal AGI, exempts Social Security, and allows a $10,000 retirement income exclusion.

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.

Oklahoma's side

Graduated income tax topping out at 4.5% for 2026 (three brackets after the 2025 reform, with trigger-based cuts scheduled until the tax is eventually repealed); no city income tax; 4.5% state sales tax plus local, about 8.6% in Oklahoma City and 8.5% in Tulsa; property tax near 0.9% effective with a homestead exemption and a 3% annual cap on homestead assessment increases; no estate tax. Oklahoma starts from federal AGI, exempts Social Security, and allows a $10,000 per person retirement income exclusion.

The RRSP

Federally deferred under Article XVIII of the treaty and deferred for Oklahoma 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 Oklahoma's graduated rates after the $10,000 retirement income exclusion. CPP and OAS, treated like Social Security under the treaty, are exempt from Oklahoma tax.

Who makes this move

Alberta and Saskatchewan oil and gas engineers to Oklahoma City's and Tulsa's producers and service companies, Canadian aerospace engineers and technicians to Tinker AFB's contractors and American Airlines' Tulsa base, Canadian healthcare professionals to OU Health and the Tulsa hospital systems, and Canadian academics to the University of Oklahoma and Oklahoma State.

Worked example

A Calgary reservoir engineer moves to Oklahoma City on June 30 with $200,000 of unrealized gain in a non-registered account, $450,000 in an RRSP, and a Calgary home sold in the departure year.

• Departure tax. $200,000 gain, $100,000 taxable, at about 48%: roughly $48,000.
• Home. Sold as a resident under the principal residence exemption.
• RRSP. No tax on departure; federal and Oklahoma deferral.
• Oklahoma City. Combined top rate about 41.5%. GST 5% becomes sales tax 8.6%. Property tax on a $400,000 home around $3,600.

"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

Practitioner note

Oklahoma's combined sales tax is nearly double Alberta's GST, and it is the line Calgary movers notice first. Property tax after the homestead exemption is low and capped, which offsets it for homeowners. The Calgary corporation is the item that needs attention before the move.
