Moving From Canada to the US With OAS
Moving from Canada to the United States does not automatically cancel your Old Age Security pension. OAS is based mainly on your age, Canadian residence history, and qualifying international agreements, rather than on current employment or contributions.
The outcome can be different for the Guaranteed Income Supplement, Allowance, and other benefits. These programs are designed around living in Canada, so a permanent move across the border may reduce or stop support even when OAS continues.
Your tax treatment, payment method, reporting duties, and eligibility should be reviewed before leaving. The details depend on how long you lived in Canada after age 18, whether the move is temporary, and whether the Canada–US social security agreement helps you meet a residence requirement.
OAS eligibility after leaving Canada
To receive a full OAS pension while living outside Canada, you generally need at least 20 years of residence in Canada after turning 18. If you have between 10 and 19 years, you may qualify for a partial pension if an international social security agreement helps you meet the rules.
Someone who applies while living in Canada may qualify with at least 10 years of Canadian residence after age 18. Moving later does not usually erase an OAS entitlement that has already been approved, but Service Canada must be notified of the new address and residency status.
The Canada–US agreement can coordinate certain social security coverage and residence periods. It does not guarantee a benefit or change every OAS condition, so applicants should request an official eligibility decision rather than relying only on years spent in either country.
How payments work in the United States
OAS can generally be paid to an eligible recipient living in the US. Payments may be deposited into a Canadian or US account, depending on the available arrangements and the information provided to Service Canada. Currency conversion can affect the amount that arrives in a US account.
A move can also change the timing of deposits, especially if banking information or a mailing address is updated. Keep records of payment dates and amounts, and use the payment schedule guide when checking expected government deposits.
If payments stop unexpectedly, contact Service Canada promptly. A missing declaration, outdated address, identity review, or returned payment can create a delay that is separate from the question of whether you remain eligible.
GIS and other income-tested benefits
The Guaranteed Income Supplement usually requires you to live in Canada. If you leave Canada for more than a permitted temporary absence, GIS can stop. In many cases, the benefit may continue for up to six months during a temporary absence, but a permanent relocation to the US normally ends GIS eligibility.
The Allowance and Allowance for the Survivor follow similar residence-based rules. They are intended for low-income spouses, common-law partners, or survivors who meet Canadian residence requirements. These benefits should not be treated as portable simply because OAS remains payable abroad.
The Canada Child Benefit generally ends when a family is no longer resident in Canada for tax and benefit purposes. Families should review their status with the Canada Revenue Agency and explore any US programs for which they may qualify.
Tax withholding and annual reporting
A Canadian non-resident receiving OAS is generally subject to non-resident withholding tax. The standard rate is often 15%, but the Canada–US tax treaty and individual circumstances can affect the final amount. You may be able to request a lower withholding rate by filing the appropriate form, such as an NR5, before the relevant tax year.
The US may also require you to report Canadian pension income on a US tax return. Whether OAS is taxable, how it is classified, and whether foreign tax credits apply depends on US rules and your broader income profile. Professional cross-border tax advice can prevent double-tax problems.
OAS recovery tax, commonly called the OAS clawback, is based on income thresholds and can affect higher-income recipients. A non-resident’s reporting obligations may differ from those of a Canadian resident, so keep OAS slips, withholding records, exchange-rate details, and other income documentation.
| Situation | Likely OAS result | Other consideration |
|---|---|---|
| Temporary stay in the US | OAS may continue | Report the absence and maintain current contact details |
| Permanent move with 20+ years of Canadian residence after age 18 | OAS can generally continue abroad | Non-resident tax withholding may apply |
| Permanent move with 10–19 years of residence | Eligibility may depend on the Canada–US agreement | Apply for an official assessment |
| Recipient of GIS who settles in the US | GIS will usually stop | Temporary absence rules may differ |
| Higher-income OAS recipient | OAS may be reduced through recovery tax | Canadian and US tax reporting may both matter |
Steps to take before crossing the border
Start by telling Service Canada about your planned move, effective date, foreign address, and banking information. Also notify the CRA when your Canadian tax residency changes. These agencies handle different records, so updating one does not necessarily update the other.
Review your private pensions, CPP, investments, health coverage, and provincial benefits separately. OAS eligibility does not automatically preserve provincial health insurance or every payment connected with living in Canada. A permanent move can also affect tax residency, estate planning, and access to provincial credits.
Useful preparation steps include:
- Confirm your Canadian residence history after age 18.
- Ask Service Canada whether the Canada–US agreement affects your eligibility.
- Arrange direct deposit and keep both Canadian and US banking records.
- Estimate non-resident withholding and possible US tax obligations.
- Check whether GIS, Allowance, provincial benefits, or family payments will stop.
For broader updates on eligibility rules and government support, review N-Grid’s coverage of social welfare programs. Rules and payment administration can change, so use current government guidance when finalizing a move.
Moving to the US does not necessarily mean losing OAS, but it can change the amount you receive, the tax deducted, and the benefits available alongside it. Confirm your residence record and cross-border tax position before departure, then keep Service Canada and the CRA informed whenever your address, banking details, or residency status changes.
