Cross-Border Tax (U.S.–Canada)

Montreal to Washington DC: International Organizations, Three Authorities, and the Reciprocity Decision

Reviewed by the Fairlight Accounting cross-border tax team — U.S. & Canadian Tax Desks

On this page

Montreal's international-organization professionals, many of them alumni of the UN agencies headquartered in the city, move to Washington's World Bank, IMF, and Inter-American Development Bank. The tax picture depends on where you live and where you work: Quebec's combined top rate of about 53.3% becomes about 47.75% in the District or about 42.75% in Northern Virginia, and international organization salaries have their own federal treatment. The departure year runs through Revenu Québec, the CRA, and the IRS.

Key takeaways

  • Two Canadian departure returns: the federal T1 and Revenu Québec's TP-1, with matching departure dates.
  • Quebec's roughly 53.3% top rate sets the departure tax. On a $300,000 unrealized gain, about $80,000.
  • The District's top rate is 10.75%; Virginia's is 5.75%; Maryland's is 5.75% plus a county piggyback. Wages are taxed where you live.
  • Salaries from the World Bank, IMF, and similar organizations are exempt from US federal income tax for non-US citizens on a G-4 visa; state treatment varies and should be documented.
  • Quebec's 14.975% combined GST and QST becomes 6% sales tax. RAMQ ends on departure.

The three-authority departure

The federal deemed disposition applies to non-registered investments, private company shares, crypto, and property outside Canada; Quebec mirrors it. Report on federal Form T1243 (with T1161 if the property list exceeds $25,000) and on the Quebec equivalents. RAMQ ends when you leave Quebec to settle outside Canada. A Montreal condo kept and rented brings NR6 and Section 216 federally plus Quebec equivalents.

Washington DC's side

The District taxes income on graduated brackets from 4% to 10.75%; Virginia's top rate is 5.75% with no county income tax; Maryland's top state rate is 5.75% plus a county piggyback tax of up to 3.2%, pushing the combined state and local rate near 9% in Montgomery and Prince George's Counties. All three tax wages where you live under their reciprocity agreements, so the residence decision, not the office location, sets the state layer. Sales tax is 6% in the District and Maryland and about 6% to 7% in Northern Virginia; property tax runs near 0.85% in the District and about 1% in the suburbs; the District and Maryland each have an estate tax (the District's exemption is about $4.99 million, Maryland's is $5 million), and Virginia has none.

The RRSP in the DC area

Federally deferred under Article XVIII of the treaty and deferred for the District, Virginia, and Maryland because all three start 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 the resident jurisdiction's income tax.

The residence decision

A worker with a downtown DC office pays about 10.75% at the top as a District resident, about 5.75% as an Arlington or Fairfax resident, and close to 9% as a Bethesda or Silver Spring resident. On a $250,000 salary the difference between Virginia and the District is roughly $10,000 a year. Virginia also has no estate tax. For most Canadian movers, Northern Virginia is the tax answer; the commute and the schools decide the rest.

International organization salaries

Under the organizations' founding instruments and the International Organizations Immunities Act, salaries paid by the World Bank, IMF, and similar bodies to non-US-citizen staff on G-4 visas are exempt from US federal income tax. The District, Virginia, and Maryland each take their own position; the District generally follows the federal exemption for G-4 holders, and the position should be documented in the first-year file. Canadian-source income (rental, investment) is taxed normally.

Who makes this move

Montreal international-organization professionals to the World Bank, IMF, and Inter-American Development Bank, Quebec policy analysts to Washington's think tanks and the Canadian Embassy, Montreal lawyers to the international trade bar, and Quebec francophone professionals to the Organization of American States.

Worked example

A Montreal economist moves to Washington on August 31 for a World Bank role with $180,000 of unrealized gain in a non-registered account, $350,000 in an RRSP, and a Plateau condo sold in the departure year.

  • Departure tax. $180,000 gain, $90,000 taxable, at about 53.3%: roughly $48,000 across the T1 and TP-1.
  • Condo. Sold as a resident under the principal residence exemption on both returns.
  • World Bank salary. Federal exemption on G-4; District treatment documented.
  • RRSP. Federally deferred; state deferral in all three jurisdictions.
  • Washington. Sales tax 14.975% becomes 6%.

"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

"If you are an employee of an international organization, you may be able to exempt your international organization compensation from U.S. income tax either under a provision, if one exists, in the international agreement creating the international organization, or by meeting the requirements of U.S. tax law." — Internal Revenue Service, Employees of Foreign Governments or International Organizations, https://www.irs.gov/individuals/international-taxpayers/employees-of-foreign-governments-or-international-organizations

Practitioner note

Montreal-to-DC files for international organization staff turn on the visa and the organization: a G-4 holder at the World Bank has a different federal and state position from a contractor at a think tank. We document the exemption position and the state residence choice in the first-year file.
