Moving from Canada to Louisiana: A Flat 3%, High Sales Tax, and the Oil, Gas, and LNG Corridor

Louisiana's petrochemical corridor along the Mississippi, its offshore oil and gas sector, and the LNG export terminals on the Gulf recruit Alberta and Newfoundland energy professionals directly. New Orleans's port, healthcare, and film sectors draw others. Louisiana overhauled its tax system in 2025: a flat 3% income tax replaced graduated brackets, offset by a higher state sales tax that stacks with some of the highest local rates in the US.

Key takeaways

• Louisiana's flat 3% income tax replaced graduated brackets in 2025. No city income tax.
• Combined sales tax runs about 9.5% to 10.5% in the major cities after the 2025 state rate increase.
• Property tax is low, near 0.55% effective, with a $75,000 homestead exemption.
• No estate tax.
• Louisiana starts from federal AGI and exempts up to $12,000 of retirement income for taxpayers 65 and older.

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.

Louisiana's side

Flat 3% state income tax; no city income tax; 5% state sales tax plus local rates that push combined rates to about 9.5% in New Orleans and above 10% in Baton Rouge and Lafayette; property tax near 0.55% effective with a $75,000 homestead exemption; no estate tax. Louisiana starts from federal AGI and exempts up to $12,000 of annual retirement income for taxpayers 65 and older.

The RRSP

Federally deferred under Article XVIII of the treaty and deferred for Louisiana 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 Louisiana's flat 3% after the retirement income exemption.

Who makes this move

Alberta and Newfoundland energy professionals to Louisiana's petrochemical plants, offshore operators, and LNG terminals, Canadian engineers to the Baton Rouge and Lake Charles industrial corridor, Canadian port and logistics staff to New Orleans, and Canadian healthcare professionals to Ochsner and the New Orleans health systems.

Worked example

A Calgary process engineer moves to Lake Charles 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 Louisiana deferral.
• Lake Charles. Combined top rate about 40%. GST 5% becomes sales tax about 10.75%. Property tax on a $400,000 home around $1,800 after homestead.

"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

Louisiana's 2025 reform traded income tax for sales tax, and Canadians moving from Alberta's 5% GST feel it: the combined rate in Baton Rouge is roughly double. Property tax after the homestead exemption is among the lowest in the US, which offsets it for homeowners.
