US-Canada Tax Relationship

The US-Canada income tax treaty addresses residence, income categories and relief from double taxation. Its saving clause generally preserves US taxation of US citizens and residents, with specified exceptions. Retirement plans, social security benefits and investment income have different rules. Review the applicable provision and your circumstances rather than assuming the treaty eliminates filing or tax.

Use a US-Canada tax consultation to discuss your filing history, Canadian accounts and which preparation services you need.

Key Tax Considerations for Canada

2026 Canadian Federal Tax Brackets

For 2026 taxable income, federal rates are 14% up to C$58,523; 20.5% on the portion over C$58,523 to C$117,045; 26% over C$117,045 to C$181,440; 29% over C$181,440 to C$258,482; and 33% above C$258,482. Provincial or territorial rates apply in addition. Each rate applies to its bracket, not your entire income.

RRSP Treaty Election & Form 8833

Check eligibility for RRSP deferral under Revenue Procedure 2014-55. Do not assume every treaty benefit requires Form 8833: the IRS lists disclosure exceptions for certain pension, social security and withholding benefits. Assess FBAR and Form 8938 separately. Form 8938 thresholds depend on filing status and whether you meet the foreign tax home and presence-abroad conditions. Form 8621 has a reporting exception for certain treaty-covered foreign pension arrangements; review the conditions before deciding how holdings within an RRSP must be reported.

TFSA: Review US Tax and Reporting Treatment

Before opening, contributing to or closing a TFSA, review its US tax and information-reporting treatment using the account agreement and investment holdings. Do not assume that Canadian tax-free treatment determines US treatment. Vanguard publishes PFIC statements for VFV and VCN, so this page does not recommend either as a way to avoid PFIC reporting.

Departure Tax: Deemed Disposition on Emigration

Ceasing Canadian tax residence can trigger a deemed sale at fair market value for certain property. Exceptions include Canadian real property and specified registered plans. Review the assets, residency dates, reporting requirements and any available elections before moving; this is not a tax on every asset.

Home Sales: Separate Eligibility Tests

A Canadian principal residence exemption is conditional; it does not make every home sale fully tax-free. Reporting and designation requirements apply. The US home-sale exclusion has its own eligibility tests and limits. Review both countries before deciding when to sell.

PFIC Rules for Canadian Mutual Funds

Review each fund and account before deciding whether Form 8621 is required. Reporting exceptions can apply, including for certain treaty-covered foreign pension arrangements. Vanguard publishes PFIC statements for VFV and VCN; these funds should not be presented as automatic ways to avoid PFIC reporting.

FBAR Filing: Accounts and Threshold

A US person generally must file an FBAR when they have a financial interest in or signature authority over foreign financial accounts whose combined value exceeds $10,000 at any time during the calendar year. Exceptions apply. FBAR is separate from the income tax return; review missing reports promptly rather than relying on a generic penalty estimate.

RESP: Education Savings Reporting

Review the RESP agreement and your role in the plan before deciding which US forms apply. IRS instructions provide reporting exceptions for certain eligible individuals and qualifying tax-favored foreign trusts. An exception to foreign-trust reporting does not resolve separate income tax, FBAR or Form 8938 obligations.

CPP, QPP, and OAS Treaty Treatment

For US residents, CPP, QPP and OAS benefits are taxable only in the United States and follow US Social Security reporting rules. Canada lists a zero non-resident withholding rate for these benefits paid to US residents. Do not apply the withholding rules for private pensions to these benefits.

Social Security Totalization Agreement

The agreement coordinates US and Canadian social security coverage; Quebec has a separate understanding. SSA says self-employed residents of Canada are assigned Canadian or Quebec coverage. A certificate of coverage establishes an exemption from US Social Security contributions: use CPT56 for CPP coverage or QUE/USA 101 for QPP coverage.

Provincial Tax Differences & Quebec

Use the CRA rate table for the relevant tax year and province or territory. For example, Alberta starts at 8% on the first C$61,200 in 2026; it is not a flat 10% across the lower brackets. The CRA links to Revenu Quebec for Quebec rates.

Streamlined Filing Compliance Procedures

Streamlined Foreign Offshore eligibility requires non-willful conduct, the applicable non-residency test and the general eligibility criteria. Eligible taxpayers must submit the required returns and information returns for the most recent three overdue tax years, six overdue FBAR years, certification, and any tax and interest due. Penalty relief requires compliance with all instructions; previously assessed penalties are not abated.

US State Tax After a Move

State filing needs a separate review. California, for example, taxes residents on all income and nonresidents on California-source income; part-year residents apply different rules to the resident and nonresident periods. Bring your move dates, remaining state ties and income records to the consultation.

T1/T4 Equivalents & Currency Conversion

US returns generally report amounts in US dollars. Use the exchange-rate method appropriate to the item and retain your conversion records. A single annual average rate is not appropriate for every transaction or reporting form.

Required US Tax Forms

Form 1040

US Individual Tax Return

Check US filing requirements using your filing status, age, worldwide gross income and any special filing triggers. Living in Canada does not by itself remove a US citizen or resident alien from these rules.

Form 2555

Foreign Earned Income Exclusion

The foreign earned income exclusion requires foreign earned income, a foreign tax home, and a qualifying residence or physical-presence test. Compare the exclusion and foreign tax credit for your circumstances; neither is automatically the better choice simply because you live in Canada.

Threshold: Eligibility and annual exclusion limit apply

Form 1116

Foreign Tax Credit

A foreign tax credit may reduce US tax on income also taxed abroad, subject to the applicable rules. Not every foreign payment qualifies. Taxes on income excluded under the foreign earned income exclusion cannot also generate a foreign tax credit.

Threshold: Dollar-for-dollar credit up to US tax on foreign income

FBAR (FinCEN 114)

Foreign Bank Account Report

Review foreign accounts, ownership and signature authority against the FBAR requirements and exceptions. File separately through FinCEN. The annual deadline is April 15, with an automatic extension to October 15.

Threshold: Aggregate foreign account value exceeds $10,000 during the year

Form 8938

FATCA Statement of Foreign Financial Assets

For qualifying taxpayers living abroad, the threshold is more than US$200,000 at year-end or US$300,000 during the year for unmarried or married-separate filers; joint filers use US$400,000 and US$600,000. Foreign tax home and presence-abroad conditions apply. Review exceptions and the requirement to file an income tax return.

Threshold: Depends on filing status and qualifying residence abroad

Form 8833

Treaty-Based Return Position Disclosure

Use Form 8833 for treaty-based return positions that require disclosure. Exceptions apply; review the form instructions for your position instead of assuming that every treaty benefit requires this form.

Threshold: Reportable treaty positions; exceptions apply

Form 8621

PFIC Annual Information Return

A US shareholder of a PFIC may need Form 8621. Filing requirements depend on ownership, transactions, elections and applicable exceptions; do not assume every fund in every account has the same reporting requirement.

Threshold: Review the applicable filing requirements and exceptions

Form 3520/3520-A

Foreign Trust Reporting

Review foreign-trust classification, your role, reportable transactions and applicable exceptions before deciding which forms are required. Check the instructions for each required form; do not assume they share an income tax return deadline.

Threshold: Review reportable events, ownership and exceptions

Form T1161

List of Properties by an Emigrant (Canadian)

Review Form T1161 when the total fair market value of property included in its calculation exceeds C$25,000 on departure. Excluded property is omitted from the calculation and list. This is an aggregate test, not a C$25,000 threshold for each property.

Illustrative Filing Scenarios

American Working in Toronto (C$120,000 Salary)

US citizen earning C$120,000 at a Toronto employer, contributing to group RRSP, has TFSA and chequing accounts at TD Canada Trust, maintains a US credit card and small US brokerage account.

Our Approach: Prepare your Canadian return, employment slips, US income records and account statements for review. Compare available credits and exclusions using your actual facts. This example does not establish a zero US tax balance or a credit carryforward.

Canadian Green Card Holder in US with RRSP

Left Canada 3 years ago, maintains RRSP with C$250,000 balance, receives CPP of C$1,200/month, owns rental condo in Vancouver, has NR status for Canadian tax purposes.

Our Approach: Review CPP under US Social Security reporting rules. For the consultation, list the RRSP, Canadian rental property and any distributions, and bring prior returns and account statements. These facts need separate review; the account balance alone does not establish every reporting obligation or a foreign tax credit.

Dual Citizen Running Small Business in Vancouver

Born in the US, living in Vancouver for 15 years, operating a web design consultancy (sole proprietor), married to Canadian spouse, two children in Canadian schools, has TFSA, RRSP, and RESP for children.

Our Approach: Bring business income and expense records, prior returns, account agreements and social insurance coverage documents. Ask which income tax and information returns apply before engaging preparation services; this example is not a residency determination or tax calculation.

Retiree Receiving CPP and OAS in the US

A retiree living in the United States receives CPP and OAS and also has an RRIF and Canadian savings account.

Our Approach: Report CPP and OAS under US Social Security rules. Review the RRIF separately rather than applying the same treatment to all Canadian retirement income. Bring benefit slips, account statements and prior returns to the consultation; this example does not estimate tax owed.

Real Estate Investor with Canadian Rental Property

US citizen living in Texas, owns a C$800,000 rental condo in Toronto purchased for C$500,000. Annual rent C$36,000, mortgage interest C$18,000, property taxes C$5,000, condo fees C$6,000.

Our Approach: Bring purchase records, improvement costs, rental income and expenses, prior returns and any periods of personal use to the consultation. Request a review of rental reporting and a separate review before selling. This example does not calculate tax, depreciation or a foreign tax credit.

Freelancer / Self-Employed Digital Nomad in Montreal

US citizen living in Montreal, working as a freelance software developer earning US$150,000/year from US clients. No Canadian employer. Has Quebec health insurance (RAMQ), opened Wealthsimple TFSA.

Our Approach: Bring records of where you performed the work, income, expenses, prior returns and social insurance coverage. Request a review of the filings and services needed in each jurisdiction. Do not close investment accounts or assume a zero US tax balance based on this example.

Frequently Asked Questions

Do I need to file US taxes if I live in Canada?

US citizens and resident aliens abroad generally follow the same income tax filing rules as those living in the United States. Filing requirements depend on gross income, filing status and age, with additional rules for situations such as self-employment. Qualifying exclusions or credits may reduce tax, but do not assume that paying Canadian tax removes a US filing requirement.

Do I need to file Form 8833 for my RRSP?

Not automatically. Revenue Procedure 2014-55 treats eligible individuals as having elected deferral for undistributed income in qualifying Canadian retirement plans. Eligibility depends on your filing and reporting history. Form 8833 also has reporting exceptions, including for certain pension and social security treaty benefits. Check the applicable requirements before filing; FBAR and Form 8938 obligations are separate.

Is my TFSA taxable in the US?

US citizens and resident aliens generally report worldwide income. Before relying on the Canadian tax-free label, have the TFSA agreement, holdings and transactions reviewed for US treatment and any required forms. Do not liquidate or replace investments solely on the basis of this guide.

What is Canadian departure tax and does it affect Americans?

Canada may treat certain property as sold when Canadian tax residence ends, subject to exceptions. Form T1243 reports deemed gains or losses; Form T1161 has a separate property-listing test. Review the US consequences and timing separately rather than assuming an automatic foreign tax credit.

Is my Canadian home sale taxable in the US?

A Canadian exemption does not establish the US result. Qualifying US taxpayers may exclude up to $250,000 of main-home gain, or up to $500,000 on a qualifying joint return. Ownership, use and other conditions apply. Review your residence history and property records before relying on either exemption.

What if I haven't filed US taxes from Canada?

Have your filing history and circumstances reviewed before choosing a catch-up procedure. Living in Canada does not by itself establish Streamlined Foreign Offshore eligibility. The IRS requires non-willful conduct and other eligibility conditions. Tax and interest remain payable, and previously assessed penalties are not automatically removed.

How are CPP and OAS payments taxed for US residents?

For US residents, CPP, QPP and OAS benefits are treated as US Social Security benefits and reported on the Social Security lines of Form 1040 or 1040-SR. Canada lists zero non-resident withholding for these benefits. The taxable amount depends on the Social Security calculation; it is not automatically zero.

What about Canadian mutual funds and PFIC?

Check the specific fund, account and Form 8621 filing rules before buying, selling or making an election. Vanguard provides PFIC statements for VFV and VCN. Request the relevant fund-year information from the issuer rather than assuming that statements are unavailable or that a Canadian ETF avoids PFIC reporting.

What is the US-Canada tax treaty rate on dividends and interest?

Treaty rates depend on the income, recipient and applicable conditions. Publication 597 explains Canadian-source investment income received by qualifying US residents. Confirm treaty eligibility and documentation before applying a reduced withholding rate; do not assume all withholding automatically becomes a US foreign tax credit.

Do I have to report my RESP to the IRS?

The answer requires reviewing your ownership, the plan and the applicable reporting rules. The Form 3520 instructions include exceptions for qualifying tax-favored foreign savings trusts and eligible individuals. Do not assume every RESP either requires foreign-trust forms or is exempt from all US reporting.

Is there a US-Canada Totalization Agreement for Social Security?

Yes. Coverage and benefit eligibility have separate rules. For Canadian-covered self-employment, request the appropriate certificate of coverage and follow SSA instructions for attaching it to the US return. Have your work and residence history reviewed rather than assuming a particular combination of years guarantees benefits.

What Canadian tax documents do I need for my US return?

For the consultation, gather prior Canadian and US returns, tax slips, assessments, account statements, retirement-plan documents and records of property transactions. Include account maximum balances and exchange-rate records. The preparer can identify additional documents after reviewing your circumstances.
