Key takeaways
- Moving to Canada does not end your US filing obligation, because the US taxes citizens and green card holders on worldwide income wherever they live.
- Canada also taxes its residents on worldwide income, so most Americans in Canada file two full returns and rely mainly on foreign tax credits to avoid paying twice.
- The income tax treaty and the totalization agreement are separate instruments, and only the totalization agreement decides whether you pay into CPP/QPP or US Social Security.
- RRSPs and RRIFs get specific US relief, while TFSAs, RESPs and most Canadian mutual funds and ETFs do not and can create US tax or reporting problems.
- Leaving Canada can trigger a Canadian departure tax on unrealized gains, and the treaty offers an election to keep the US side in step.
Do Americans living in Canada still file US taxes?
Yes. The United States taxes its citizens and resident aliens, including green card holders, on worldwide income wherever they live. The IRS says Americans abroad generally file and pay "in the same way" as people living in the US (IRS, U.S. citizens and residents abroad – Filing requirements, reviewed Sept. 28, 2026).
Filing threshold. Whether you must file depends on worldwide gross income, filing status and age, using the table in IRS Publication 54. Income excluded under the Foreign Earned Income Exclusion still counts. For a single filer under 65, the threshold generally tracks the standard deduction: $16,100 for 2026 and $15,750 for 2025, indexed annually (IRS 2026 inflation release) — this guide inferred the 2026 threshold from the standard deduction rather than reading it directly off the published 2026 Publication 54 table. A much lower threshold applies to married people filing separately, which matters for Americans married to Canadians. Self-employed people generally must file once net self-employment earnings reach $400, per secondary sources not independently refetched for this guide.

When does Canada treat you as a tax resident, and what does it tax?
Residence is a question of fact, not immigration status. The Income Tax Act does not define "resident." The Canada Revenue Agency (CRA) applies case law and weighs residential ties. Its Income Tax Folio S5-F1-C1 (modified Jan. 20, 2026) says a home, a spouse or common-law partner, and dependants in Canada will "almost always" be significant ties. Secondary ties include a provincial health card, driver's license, bank accounts and personal property. The CRA adds that someone who obtains permanent resident status and provincial health coverage will, except in exceptional circumstances, be resident. That is a factual inference, not a rule that immigration status equals tax residence.
When residency starts. Someone who establishes ties is generally resident from the date of entering Canada (Folio ¶1.28) and is taxed on worldwide income only for the resident part of that year.
The 183-day rule. A person who is not factually resident but "sojourns" in Canada for 183 days or more in a calendar year is deemed resident for the whole year under paragraph 250(1)(a) (Folio ¶1.32). Daily commuting is not sojourning.
Treaty override. If the treaty tie-breaker makes you a US resident, subsection 250(5) deems you a non-resident of Canada for all purposes of the Act (Folio ¶1.37–1.38).
What Canada taxes (confirmed in the statute). Subsection 2(1) of the Income Tax Act imposes tax on the taxable income of "every person resident in Canada at any time in the year," and paragraph 3(a) builds that income from sources "inside or outside Canada." Together these charging provisions establish worldwide taxation of residents, not a territorial or remittance basis.
Rates. 2026 federal rates run from 14% on taxable income up to $58,523 to 33% above $258,482, with brackets at $117,045 and $181,440 (CRA 2026 rates page, modified June 25, 2026). Brackets are indexed annually. Provincial tax is added based on your province on December 31. Quebec administers its own personal income tax through Revenu Québec.
Local filing. The 2026 T1 return is due Friday, April 30, 2027. If you or your spouse or partner is self-employed, filing is due June 15, 2027, but any balance owing is still due April 30 (CRA, Important dates for individuals). Canada's tax year is the calendar year, like the US year.
Is there a US–Canada tax treaty?
Yes. The Convention with Respect to Taxes on Income and on Capital was signed September 26, 1980 and entered into force August 16, 1984. Protocols followed in 1983, 1984, 1995, 1997 and 2007; Canada's consolidated treaty act shows its last amendment on December 15, 2008 (IRS treaty text; Treasury Technical Explanation of the 2007 Protocol; Canada–United States Tax Convention Act, 1984).
The saving clause. Article XXIX(2) lets the US tax its citizens "as if there were no convention." Article XXIX(3) keeps certain protections for citizens, including Article XXIV (elimination of double taxation), parts of Article XVIII (pensions and social security) and Article XXV (non-discrimination). Most rate reductions therefore help Canadians investing in the US, not Americans living in Canada.
Tie-breaker (Article IV(2)). For a dual resident: permanent home, then center of vital interests, then habitual abode, then citizenship, then mutual agreement. A US citizen who is a Canadian resident under the tie-breaker is still taxed by the US because of the saving clause. The test matters most for green card holders.
Relief for US citizens in Canada (Article XXIV(4)–(6)). Canada credits US tax on US-source income only up to what the US would charge a non-citizen. The US then credits the remaining Canadian tax, and income can be re-sourced to Canada so the credit works.
Pensions (Article XVIII). The 2007 Technical Explanation confirms that "pensions" includes RRSP and RRIF payments as well as US IRAs and 401(k)s. Article XVIII(7) lets a plan beneficiary elect to defer residence-country tax on income accrued in the plan until distribution. Roth IRAs generally stay "pensions" for Canadian purposes, but contributions made while resident in Canada lose that status for the new money.
Social security benefits (Article XVIII(5), as amended in 1997). Benefits are generally taxable only in the recipient's country of residence; US Social Security paid to a Canadian resident is taxed like CPP, with 15% exempt. In non-precedential Field Service Advice 199932046, the IRS concluded it may not tax US Social Security paid to US citizens resident in Canada. The parallel rule for CPP, QPP and OAS covers residents of the US, not US citizens living in Canada; reading the 1997 text alone suggests those benefits are reportable on the US return with a credit, though this guide did not confirm that reading beyond the treaty text itself.
Dividends (Article X). Canada may withhold up to 15% on portfolio dividends paid to US residents, or 5% for a company owning at least 10% of the voting stock.
Collection (Article XXVI A). Each country can collect the other's finalized tax debts, but not for a period in which the taxpayer was a citizen of the country asked to collect (Article XXVI A(8)(a)). This protects dual US–Canadian citizens for those periods, not Americans who are not Canadian citizens.
Death (Article XXIX B). Canada has no estate tax but taxes a deemed disposition at death. Article XXIX B coordinates this with the US estate tax, including a credit for Canadian income tax arising on death (paragraph 7).
How do you avoid paying tax twice?
Two US tools exist, and they cannot be used on the same dollars.
Foreign tax credit (Form 1116). A dollar-for-dollar credit for Canadian income tax, limited to the US tax on foreign-source income in each category, mainly general (wages, business) and passive (interest, dividends). Unused credits can generally be carried back one year and forward ten (IRC §904(c)), per secondary sources not independently refetched for this guide. Because combined Canadian rates are often at or above US rates, the credit frequently eliminates US tax on Canadian wages and builds carryovers.
Foreign Earned Income Exclusion (Form 2555). Excludes up to $132,900 of foreign earned income for 2026 ($130,000 for 2025), indexed annually (IRS 2026 inflation release). It covers earned income only. It does not reduce US self-employment tax, and Canadian tax on excluded income cannot also be credited (IRC §911(d)(6)) — again per secondary sources. Revoking it generally bars reuse for five years without IRS consent, also per secondary sources.
Which fits. In higher-tax provinces the credit often works better because it also covers investment income and keeps carryovers. The exclusion can suit lower earners or years with unusually low Canadian tax, such as an arrival year. Model both for your province and income mix.
Timing. Both countries use the calendar year, so there is no fiscal-year mismatch. Mismatches can still arise when one country taxes an event the other defers, such as Canada's deemed disposition on emigration or at death; Articles XIII(7) and XXIX B address these.
Social security: will you pay both CPP and US Social Security?
The totalization agreement, separate from the income tax treaty, entered into force August 1, 1984 (SSA). It covers Old Age Security and the Canada Pension Plan; a separate Understanding covers Quebec's QPP.
Employees. The basic rule is territorial: you are covered where you work. Under the detached-worker exception, an employee sent by a US employer to Canada on a temporary assignment expected to last five years or less stays in the US system; work for a foreign affiliate requires a section 3121(l) agreement (SSA overview). The employer requests a certificate of US coverage from SSA.
Self-employed. Coverage follows residence: a self-employed person living in Canada is covered by CPP (or QPP) and exempt from US self-employment tax (SSA, Totalization Agreement with Canada). The exemption must be documented. Request a certificate of Canadian coverage with CRA form CPT56 (or QUE/USA 101 from Retraite Québec); SSA says self-employed workers should attach a copy to their US return every year.
CPP in 2026. Employees and employers each pay 5.95% on earnings between the $3,500 exemption and $74,600, up to $4,230.45 each; self-employed people pay both halves, up to $8,460.90 (CRA table, modified Oct. 31, 2025). A second tier, CPP2, applies above $74,600. Figures are indexed annually.
Benefits. SSA can count CPP/QPP periods if you have at least six US quarters of coverage. Canada can count US credits toward OAS residence if you lived in Canada at least a year after age 18. OAS generally requires 10 years of residence after 18, or 20 years to be paid abroad (SSA).
Which US forms apply to accounts and assets in Canada?
FBAR. Required if your foreign financial accounts total more than $10,000 at any time in the year, including signature-only accounts at work. The threshold is not indexed. RRSPs, RRIFs, TFSAs, RESPs and brokerage accounts generally count.
Form 8938. For people living abroad, required if specified foreign financial assets exceed $200,000 at year-end or $300,000 at any time ($400,000 and $600,000 for joint filers). It is filed with Form 1040 and is separate from the FBAR (IRS comparison chart).
FATCA and CRS. Canada's FATCA agreement with the US entered into force June 27, 2014, implemented through Part XVIII of the Income Tax Act. Canadian institutions identify accounts held by US persons and report them to the CRA, which shares them with the IRS. Part XIX, enacted December 15, 2016, implements the Common Reporting Standard, with collection from July 1, 2017 (CRA FATCA/CRS page). Expect banks to ask about US citizenship and your US taxpayer number.
Local pensions, retirement accounts and investment funds
RRSP and RRIF. Under Revenue Procedure 2014-55, eligible US individuals get the treaty deferral automatically and need not file Forms 3520 or 3520-A for these plans (IRS filing-requirements page). They still count for the FBAR and Form 8938. Contributions are deductible in Canada but generally not on the US return. Article XVIII(13) may allow limited US deductions for some contributions by US citizens employed in Canada, though this guide did not confirm that reading.
TFSA. No treaty provision or Revenue Procedure covers it, so income inside a TFSA is generally taxable on the US return as earned. Practitioners disagree on whether a TFSA is a foreign grantor trust requiring Forms 3520 and 3520-A. 2024 proposed regulations (Prop. Reg. §1.6048-5) exempt certain tax-favored foreign trusts from Form 3520 reporting; whether a TFSA qualifies is unsettled. Many advisers suggest Americans avoid opening one.
RESP and RDSP. These may be foreign trusts for US purposes. The proposed regulations cover trusts providing educational, medical or disability benefits, and taxpayers may rely on them for tax years ending after May 8, 2024 if applied consistently (IRS filing-requirements page). Qualification depends on plan terms, and the relief is from reporting, not tax.
FHSA. No IRS guidance specific to the First Home Savings Account was found for this guide; treat its US status as unsettled.
Canadian mutual funds and ETFs. Canadian pooled funds are widely treated as PFICs by practitioners, requiring Form 8621 and facing harsh default treatment unless an election is available. Funds inside an RRSP or RRIF generally fall under the treaty deferral; the same funds in a TFSA or taxable account do not.
Running a business or company in Canada
Sole proprietor. Report on Canada's T2125 and US Schedule C. Contributions go to CPP/QPP, and US self-employment tax is waived only with the certificate of coverage described above.
Corporation: check the classification first. US regulations list "Canada, Corporation and Company" as a per se corporation, which cannot elect flow-through treatment (Treas. Reg. §301.7701-2(b)(8)(i)). The exception is a Nova Scotia unlimited liability company or any company whose owners all have unlimited liability (§301.7701-2(b)(8)(ii)(A)(1)); these are eligible entities that can be flow-through. Canadian partnerships are generally eligible entities too. ULCs can raise hybrid issues under treaty Article IV(7).
CFC exposure. A Canadian corporation more than 50% owned by US shareholders who each hold at least 10%, such as a one-person consulting company, is a controlled foreign corporation. Subpart F income and the section 951A inclusion can be taxed to you yearly without a dividend. For tax years beginning after December 31, 2025, the One Big Beautiful Bill Act renamed GILTI "net CFC tested income" (NCTI) and changed the calculation, per secondary summaries of the law. A section 962 election or the high-tax exclusion may reduce the cost. Expect Form 5471 annually, and Forms 8992 and 8993 where relevant.
Salary versus dividends. Common Canadian advice favors dividends, but dividends are not earned income for the exclusion and credits may not line up. Model both sides first.
Buying, renting and selling property
Selling your home. Canada generally exempts the gain on a designated principal residence, and the sale is reported on your return — this guide did not independently confirm the exemption's mechanics against the CRA's own page. The US exclusion under IRC §121 is capped at $250,000, or $500,000 for qualifying joint filers, after ownership and use as a main home for two of the five years before sale; the caps are fixed in the statute and, per secondary sources, do not depend on where the home is. Gain above the cap is US-taxable even if Canada exempts it, and with no Canadian tax there may be nothing to credit. The US gain is measured in dollars, so currency moves alone can raise it.
Canadian-dollar mortgage. Repaying a foreign-currency mortgage on a personal residence is a separate transaction from selling the home. If the Canadian dollar has weakened since you borrowed, repayment produces a taxable currency gain; a currency loss is not deductible and cannot offset the gain on the house (Rev. Rul. 90-79; Quijano v. United States, 93 F.3d 26 (1st Cir. 1996)).
Canadian capital gains. One-half of a capital gain is included in income (ITA s.38); a proposed increase to two-thirds was cancelled March 21, 2025, per secondary press coverage.
Rentals. Rent is taxable in Canada and on your US return with a credit. Canadian capital cost allowance does not carry over to US depreciation, so keep separate records.
Employment, equity compensation and remote work for a US employer
Source. Wages are generally sourced where the work is done. Remote work from Canada for a US employer is generally Canadian-source, taxed by Canada as your residence and by the US as your citizenship, with a credit.
Withholding. If a US employer keeps withholding only US tax, you can be over-withheld in the US and short in Canada. The employer may also face Canadian payroll obligations and permanent establishment questions under treaty Article V, though this guide did not confirm the specifics. A remote employee not sent on a temporary assignment is generally covered by CPP where the work is done.
Options and RSUs. Canada generally taxes an employee stock-option benefit as employment income on exercise; a one-half deduction may apply, subject for many employers to a $200,000 annual vesting limit (CRA, Employee security (stock) options). Paragraph 6 of the 2007 Protocol's General Note splits option income by days of principal employment in each country between grant and exercise (2007 Technical Explanation). RSUs are generally taxed as employment income at vesting or settlement in both countries, but timing can differ.
Leaving Canada
Departure tax. On ceasing residence, Canada generally deems you to have sold most property at fair market value (ITA s.128.1), reported on Form T1243; Form T1161 may also be required, with a $25,000 threshold commonly cited in secondary sources. Excluded property includes Canadian real property, pension rights and certain employee options (2007 Technical Explanation). Some short-term residents can exclude property owned on arrival, per secondary sources.
Deferral. Form T1244 defers payment. If federal tax on the deemed disposition exceeds $16,500 ($13,777.50 for former Quebec residents), you must post security (CRA, Dispositions of property for emigrants).
Matching the US side. Treaty Article XIII(7), as revised in 2007, lets you elect for US purposes to be treated as selling and repurchasing the property at fair market value at the Canadian deemed disposition, so the US gain and Canadian tax fall in the same year.
US side. There is no US exit tax for leaving Canada. IRC §877A applies only if you renounce US citizenship or, as a long-term green card holder, give up residence, and only if you meet its tests — this guide did not independently verify those tests against the statute for this particular guide.
Mistakes Americans commonly make in Canada
- Treating the TFSA as tax-free. It is tax-free only in Canada.
- Holding Canadian mutual funds or ETFs outside an RRSP. These are commonly PFICs.
- Skipping the CPT56 certificate. Without it, the IRS can assess self-employment tax even though you paid CPP.
- Defaulting to the exclusion. The foreign tax credit often works better in Canada, and switching back is restricted.
- Missing FBAR accounts. RRSPs, TFSAs, RESPs, joint accounts with a spouse and signature-authority accounts are often missed.
- Incorporating on standard Canadian advice. A Canadian corporation is a per se corporation and, for a sole American owner, a CFC.
- Selling a home without checking the US side. The §121 cap and a Canadian-dollar mortgage can produce US tax.
- Leaving without planning the departure tax and the Article XIII(7) election.
Checklist
Before moving: gather recent US returns; ask your employer whether a certificate of US coverage applies; hold off on TFSAs and Canadian funds until you have advice.
First 90 days: get a Social Insurance Number and provincial health coverage; record your entry date and asset values on arrival; if self-employed, request a certificate of coverage; give banks your US taxpayer number when asked.
Every year: file the T1 (and Quebec return) by April 30; file Form 1040 with Form 1116 or 2555 and Form 8938 if required; file the FBAR; file Forms 8621 and 5471 where applicable; attach the coverage certificate if self-employed; track credit carryovers.
Before leaving: value assets for T1243 and T1161; decide on the T1244 deferral and Article XIII(7) election; plan any RRSP, TFSA or home sale; consider Form NR73 for a CRA residency opinion.
Frequently asked questions
Do I have to file US taxes if I live in Canada? Generally yes, if worldwide gross income meets your threshold. Excluded income still counts.
Does the US–Canada tax treaty stop double taxation for Americans? Not by itself. The saving clause preserves US taxation of citizens; relief comes mainly from foreign tax credits and Article XXIV.
Is my TFSA taxable in the US? Generally yes, and its reporting treatment is unsettled.
Do I need to report my RRSP to the IRS? Yes on the FBAR and, above the threshold, Form 8938. Revenue Procedure 2014-55 removes Form 3520 reporting and makes the deferral automatic.
Will I pay both CPP and US Social Security? Generally no, but self-employed people need a certificate of coverage to prove the US exemption.
Will the CRA collect my IRS debt? It can, except for periods in which you were a Canadian citizen.
When to hire a professional
- Self-employment or a Canadian corporation: a cross-border CPA or Enrolled Agent preparing both returns, with Form 5471 experience.
- TFSA, RESP, FHSA or Canadian funds: a preparer experienced in PFIC and foreign trust reporting.
- Equity compensation: a cross-border adviser familiar with treaty option allocation.
- Missed FBARs or returns: a US tax attorney or Enrolled Agent experienced with IRS compliance programs.
- Leaving Canada with significant assets: a Canadian CPA working with a US preparer.
- Considering renouncing citizenship: a US tax attorney, before you start.
