Vancouver to Portland: The I-5 Corridor, No Sales Tax, and Two Local Income Taxes

Vancouver and Portland are five hours apart on I-5 and share a tech, outdoor-industry, and clean-energy workforce. The tax picture is nearly lateral on income: BC's combined top rate of about 53.5% becomes about 51% inside Portland or about 47% in Washington County. BC's 12% sales tax becomes zero, and the Vancouver home left behind is the planning item.

Key takeaways

• BC's roughly 53.5% top rate sets the departure tax. On a $300,000 unrealized gain, about $80,000.
• Oregon's top rate is 9.9%; Portland's county and Metro taxes push the combined top rate near 51%.
• Oregon follows the treaty's RRSP deferral.
• BC's 12% combined GST and PST becomes zero sales tax.
• A Vancouver home kept empty faces three vacancy taxes. MSP ends on permanent departure. Oregon's estate tax exemption is $1 million.

The BC departure

Departure tax applies to non-registered investments, private company shares, crypto, and foreign property at fair market value on the departure date. BC 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 for illiquid assets. The Vancouver home is excluded, but kept empty it invites BC's Speculation and Vacancy Tax, Vancouver's Empty Homes Tax, and the federal Underused Housing Tax; rent it under NR6 and Section 216, or sell in the departure year. MSP ends on permanent departure.

Portland's side

Oregon's graduated state income tax tops out at 9.9% above roughly $125,000 (single); Portland residents in Multnomah County also pay the Preschool for All tax (1.5% above $125,000 single, 3% above $250,000) and the Metro Supportive Housing Services tax (1% above $125,000), which together push the combined federal, state, and local top rate near 51%; no sales tax anywhere in Oregon; property tax near 1% effective; estate tax on estates above $1 million with rates from 10% to 16%.

The RRSP in Oregon

Federally deferred under Article XVIII of the treaty and deferred for Oregon because the state starts from federal taxable income. Withdrawals face 25% Canadian withholding on lump sums, 15% on periodic RRIF payments within the treaty limit, a US foreign tax credit federally, and Oregon's graduated rates.

Who makes this move

Vancouver software engineers to Portland's tech employers, BC hardware engineers to Intel Hillsboro, Vancouver outdoor-industry professionals to Nike and Columbia, and BC clean-energy staff to Portland's renewable energy firms.

Worked example

A Vancouver software engineer moves to Beaverton on May 31 with $200,000 of unrealized gain in a non-registered account, $350,000 in an RRSP, and a Vancouver condo sold in the departure year.

• Departure tax. $200,000 gain, $100,000 taxable, at about 53.5%: roughly $53,500.
• Condo. Sold as a resident under the principal residence exemption. No vacancy taxes.
• RRSP. No tax on departure; federal and Oregon deferral.
• Beaverton. Combined top rate about 47% outside Multnomah County. Sales tax 12% becomes zero.

"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

Vancouver-to-Portland clients often ask whether Washington State across the river is better: no income tax, but a capital gains excise and a 10% sales tax. For a salaried worker with a modest portfolio, Vancouver, Washington usually wins; for a retiree drawing a RRIF, it is closer. We run both.
