How the Windfall Elimination Provision Impacts Canadians with U.S. Social Security

For many Canadians who have spent part of their careers working in the United States, understanding how U.S. Social Security interacts with Canadian pensions is essential. One of the most confusing and controversial rules affecting cross-border retirees has been the Windfall Elimination Provision (WEP).

This article explains what WEP is, why it was introduced, how it used to affect Canadians, the major changes now that it has been repealed, and what steps Canadians should take to make the most of their retirement income.

1. What is the Windfall Elimination Provision (WEP)?

The Windfall Elimination Provision (WEP) was a U.S. Social Security rule that reduced retirement benefits for people who received a pension from employment not covered by Social Security.

Normally, U.S. Social Security benefits are calculated based on your average indexed monthly earnings (AIME). The formula uses different percentage factors to determine your Primary Insurance Amount (PIA). Workers with lower lifetime earnings receive a higher replacement rate, reflecting the program’s progressive design.

However, if a person also received a pension from non-covered work—such as a foreign pension or a government job that did not pay into Social Security—the U.S. Social Security Administration considered that person at risk of receiving a “windfall.” The WEP therefore reduced the first percentage factor in the formula, lowering the benefit amount.

For example:

  • Without WEP, the first factor (90%) might apply to your lowest tier of earnings.

  • With WEP, that factor could drop to as low as 40%, depending on how many years of “substantial earnings” you had under Social Security.

  • The more years of covered work you had (up to 30 years), the smaller the reduction.

In short, the WEP was designed to adjust Social Security benefits downward for anyone who also had a pension from non-covered employment.

2. Why Did the U.S. Create WEP?

The U.S. introduced the Windfall Elimination Provision in 1983 to address perceived fairness issues in the Social Security system.

The problem was that the formula for determining benefits assumed that low-average lifetime earnings indicated a low-income worker who had contributed to Social Security for most of their career. But when someone split their career between covered and non-covered employment, they could appear to have low covered earnings even though they had a full career and an additional pension.

The WEP was designed to prevent such individuals from receiving disproportionately high Social Security benefits.

While the intent was fairness, many argued that it penalized honest workers—especially teachers, government employees, and foreign workers—who had simply spent part of their careers in systems outside Social Security. Canadians working cross-border were among those affected.

3. How WEP Affected Canadians with U.S. Social Security

3.1 Who Was Impacted

Canadians who worked in both countries were often caught by WEP. This included:

  • Canadians who worked in the U.S. long enough to earn 40 quarters (10 years) of Social Security coverage.

  • Canadians who also contributed to the Canada Pension Plan (CPP) or Québec Pension Plan (QPP) for their Canadian work.

  • Canadians receiving any employer pension from Canadian employment not covered by U.S. Social Security.

For these individuals, the U.S. considered their Canadian pension a non-covered pension, which could trigger the WEP reduction on their U.S. Social Security benefit.

3.2 How the Reduction Worked

Under WEP, your U.S. benefit was calculated normally and then reduced. The reduction depended on your years of substantial earnings under U.S. Social Security.

  • If you had 30 years or more of substantial covered earnings, WEP did not apply.

  • If you had 21–29 years, the reduction was smaller.

  • If you had 20 years or fewer, the reduction was greatest—often reducing benefits by hundreds of dollars per month.

The reduction was capped at no more than half of your non-covered pension amount.

For example, a Canadian receiving $1,000 per month in CPP could see their U.S. benefit reduced by up to $500 under the old WEP rules.

3.3 Why It Was a Big Issue for Canadians

For Canadians who divided their careers between both countries, this rule created confusion and frustration. They often contributed fairly to both pension systems, only to see their U.S. Social Security benefit reduced because of their Canadian pension.

The result: cross-border retirees often received lower U.S. benefits than they expected. Many Canadians felt the rule unfairly penalized international workers who had paid into both systems separately.

4. The Repeal of WEP and Its Impact on Canadians

In early 2025, the U.S. Congress passed the Social Security Fairness Act, which repealed both the Windfall Elimination Provision (WEP) and the Government Pension Offset (GPO).

The repeal applies to benefits payable for months after December 2023. That means anyone who previously had their benefits reduced by WEP will now have them recalculated without the WEP adjustment.

4.1 What the Repeal Means

For Canadians, this is excellent news. It means:

  • Higher monthly U.S. Social Security benefits going forward.

  • Possible retroactive payments for the difference between January 2024 and the date of recalculation.

  • Simplified retirement planning, with fewer complex cross-border rules to worry about.

4.2 Who Benefits

The repeal benefits:

  • Canadians already receiving reduced U.S. benefits due to WEP.

  • Canadians soon to claim U.S. Social Security while also receiving CPP/QPP or a Canadian pension.

  • Dual citizens and cross-border retirees with mixed work histories.

If you are already receiving U.S. benefits, you should review your Social Security statement or contact the SSA to confirm how your benefit has changed and whether you’re owed retroactive payments.

5. What Has Changed and What Remains the Same

5.1 What Has Changed

  • No more WEP reductions on U.S. Social Security benefits.

  • Canadians with CPP/QPP or other non-covered pensions will now receive the full U.S. benefit they earned.

  • Retroactive payments may be issued for benefits reduced since January 2024.

  • Simpler retirement planning for cross-border Canadians.

5.2 What Remains the Same

Even with WEP gone, other rules and interactions still matter:

  • You still need 40 U.S. work credits (10 years) to qualify for your own U.S. Social Security benefit.

  • The U.S.–Canada Totalization Agreement remains in effect, allowing you to combine work periods from both countries to meet eligibility requirements.

  • Your Canadian pensions (CPP, QPP, OAS) remain governed by Canadian rules and taxation.

  • U.S. Social Security benefits are still taxable in Canada, though the tax treaty provides relief by allowing you to deduct a portion of that income.

  • Currency exchange and residency status continue to influence your overall retirement income.

5.3 Tax and Residency Implications

If you live in Canada and receive U.S. Social Security, the income must be reported on your Canadian tax return. However, the Canada–U.S. tax treaty allows you to exclude 15% of the benefit from taxable income in Canada.

If you live in the U.S., your benefits are taxed under U.S. rules.
If you move between countries, the treaty ensures you won’t be double-taxed, but professional tax advice is still essential.

6. Planning Considerations for Canadians with U.S. and Canadian Pensions

Even without WEP, Canadians with cross-border pensions face important financial planning questions. Here are key steps to consider:

6.1 Verify Your Eligibility

  • Review your U.S. Social Security statement online or request one to confirm your work credits.

  • Verify your Canadian pension contributions with the Canada Pension Plan or Québec Pension Plan.

  • Check whether you qualify for Old Age Security (OAS) based on your years of residence in Canada.

6.2 Estimate Your Benefits

  • Use online calculators or contact the SSA to estimate your U.S. Social Security benefit.

  • Estimate your Canadian CPP/QPP benefit using Service Canada tools.

  • Combine the two for a clearer picture of your total retirement income.

6.3 Check for Retroactive Payments

If your U.S. benefit was reduced under WEP, contact the Social Security Administration to see if you are due a retroactive payment.

The SSA is expected to automatically adjust benefits, but confirming your individual case ensures you don’t miss out on any owed amount.

6.4 Integrate Both Pension Systems into One Plan

Plan your retirement income holistically by considering:

  • The timing of when you claim each benefit.

  • The exchange rate and how currency fluctuations affect income.

  • The tax treatment in both countries.

  • The potential impact on other income sources, such as RRSPs, RRIFs, or U.S. 401(k)s.

6.5 Get Professional Advice

Cross-border retirement planning is complex. It’s best to consult:

  • A cross-border financial planner familiar with both Canadian and U.S. pension systems.

  • A tax professional experienced in Canada–U.S. treaty rules.

  • Legal or estate planners if you hold assets or residency ties in both countries.

A small investment in professional advice can prevent costly mistakes and ensure you receive every dollar you’re entitled to.

7. Frequently Asked Questions (FAQs)

Q1: What is the Windfall Elimination Provision (WEP)?
The WEP was a U.S. rule that reduced Social Security benefits for people who also received a pension from work not covered by Social Security, such as a Canadian pension (CPP or QPP).

Q2: Does the WEP still apply to Canadians?
No. The WEP was repealed effective for benefits payable after December 2023. Canadians will now receive full Social Security benefits without the WEP reduction.

Q3: I already receive U.S. Social Security and a CPP pension. Will my benefit increase?
Yes. If your benefit was reduced by WEP, the U.S. Social Security Administration will recalculate your benefit. You may receive higher payments and possibly a retroactive adjustment starting from January 2024.

Q4: Will this repeal affect my Canadian CPP or OAS benefits?
No. The repeal of WEP only affects your U.S. Social Security benefits. Your Canadian pensions remain governed by Canadian laws.

Q5: Can I use my Canadian work history to qualify for U.S. Social Security?
Yes, under the U.S.–Canada Totalization Agreement, you can combine Canadian and U.S. work periods to meet eligibility thresholds. However, your benefit amount is still based only on your U.S. earnings.

Q6: How are U.S. Social Security benefits taxed in Canada?
If you live in Canada, your U.S. benefits are reported as income but only 85% is taxable, thanks to the Canada–U.S. tax treaty. You may also be eligible for foreign tax credits if any U.S. tax was withheld.

Q7: How should I plan my retirement income after the WEP repeal?
Recalculate your U.S. benefit, integrate it with your Canadian pensions, review tax impacts, and adjust your retirement strategy. Consider delaying or advancing benefits depending on your overall income and lifestyle goals.

Q8: Will there be any other reductions on my U.S. benefits?
The WEP and GPO are repealed, but standard Social Security rules—such as early-retirement reductions or taxation—still apply.

8. Summary

The Windfall Elimination Provision was a U.S. Social Security rule that reduced benefits for people who also received a pension from non-covered employment. For many Canadians who worked in both countries, this meant lower U.S. benefits because the Canada Pension Plan was treated as a non-covered pension.

As of 2025, the WEP has been repealed, ending decades of confusion and frustration for cross-border retirees. Canadians will now receive full U.S. Social Security benefits without a WEP reduction, and some may receive retroactive payments for amounts previously withheld.

However, while WEP is gone, retirement planning for Canadians with ties to both countries still requires careful attention to eligibility, taxes, and timing.

9. Conclusion

The repeal of the Windfall Elimination Provision marks a significant victory for Canadians who worked in the United States and contributed to both pension systems. It ensures fairer treatment and higher benefits for those who earned their Social Security entitlements honestly.

Canadians who were previously affected should verify their new benefit amounts and check for retroactive adjustments. Those planning retirement now have a simpler and more predictable outlook for their U.S. Social Security income.

Even without WEP, cross-border retirement planning remains complex. Taxes, currency, and timing all influence your total income. Engaging a qualified cross-border financial or tax professional can help maximize your income and ensure you take full advantage of the opportunities created by this historic change.

By staying informed and proactive, Canadians with U.S. Social Security benefits can look forward to a smoother, fairer, and more financially secure retirement.
