OAS Calculator 2025 – Canada Old Age Security Pension Updated February 2026
Old Age Security (OAS) is a monthly pension payment available to most Canadians aged 65 and older. Unlike the Canada Pension Plan (CPP), OAS is funded through general tax revenues and does not require contributions during your working years. Our free OAS calculator helps you estimate your monthly pension amount and determine if you may be subject to the OAS clawback based on your income level.
Understanding your OAS entitlement helps with retirement planning and budgeting. Whether you are approaching retirement age or planning years ahead, knowing your pension amount allows you to make informed decisions about deferral, additional savings, and overall retirement income strategy.
What Is Old Age Security (OAS)?
Old Age Security is Canada's foundational pension program, established in 1952. It provides a basic monthly income to seniors to help cover living expenses in retirement. Key features include:
- Universal Benefit: Available to most seniors aged 65+ who meet residency requirements
- Tax-Funded: Paid from general government revenues, not individual contributions
- Monthly Payments: Paid every month for life, indexed quarterly to inflation
- Taxable Income: OAS payments are taxable and must be reported on your tax return
- Supplement Available: Low-income seniors may also qualify for GIS
Key Takeaways
- Eligibility Age: 65 years old (can be deferred until 70)
- Maximum Monthly Payment (Jan-Mar 2025): $727.67 for ages 65-74
- Enhanced Amount (75+): $800.44 per month (10% increase at age 75)
- Residency Required: 40 years in Canada after age 18 for full pension
- Clawback Threshold (2024): Starts at $90,997 net income
- Full Clawback: At $148,179 net income (ages 65-74)
OAS Eligibility Requirements
To qualify for Old Age Security, you must meet these criteria:
Age Requirement
You must be at least 65 years old. You can choose to start receiving OAS at 65 or defer it to receive a higher monthly amount later.
Legal Status
You must be a Canadian citizen or legal resident of Canada when your pension application is approved.
Residency Requirement
The amount of OAS you receive depends on how long you have lived in Canada after age 18:
| Years in Canada (after age 18) | OAS Pension Amount |
|---|---|
| 40+ years | Full pension (100%) |
| 30-39 years | Partial pension (75-97.5%) |
| 20-29 years | Partial pension (50-72.5%) |
| 10-19 years | Partial pension (25-47.5%) |
| Less than 10 years | No OAS (unless covered by international agreement) |
International Agreements
Canada has social security agreements with many countries. If you lived in one of these countries, those years may count toward your Canadian residency requirement.

Example Calculation
Scenario: Margaret is 65, lived in Canada for 40 years, and has a net income of $45,000.
- Full OAS entitlement: $727.67/month (Jan-Mar 2025 rate)
- Income level: Below clawback threshold ($90,997)
- Clawback amount: $0
- Monthly OAS payment: $727.67
- Annual OAS income: $8,732.04
Margaret receives the full OAS pension without any clawback.
Current OAS Payment Amounts (January-March 2025)
OAS payment amounts are reviewed quarterly and adjusted for inflation:
| Age Group | Maximum Monthly Payment | Annual Amount |
|---|---|---|
| Ages 65 to 74 | $727.67 | $8,732.04 |
| Age 75 and over | $800.44 | $9,605.28 |
10% Increase at Age 75
Starting July 2022, seniors aged 75 and over receive a permanent 10% increase in their OAS pension. If you are already receiving OAS when you turn 75, the increase is automatic. There is no need to apply.
Partial Pension Calculation
If you have less than 40 years of Canadian residency, your pension is calculated as:
For example, with 30 years in Canada: $727.67 × (30/40) = $545.75/month
Understanding the OAS Clawback (Recovery Tax)
High-income seniors may have to repay some or all of their OAS pension through the OAS Recovery Tax, commonly called the clawback.
How the Clawback Works
The clawback applies to your net income (line 23600 of your tax return) before adjustments:
| Age Group | Minimum Income for Clawback | Income for Full Clawback |
|---|---|---|
| Ages 65 to 74 (2024) | $90,997 | $148,179 |
| Age 75 and over (2024) | $90,997 | $153,771 |
Clawback Calculation
For every dollar of income above the minimum threshold, you repay 15 cents of OAS:
Clawback Example
Scenario: Robert is 68 with a net income of $110,000.
- Income over threshold: $110,000 - $90,997 = $19,003
- Clawback amount: $19,003 × 15% = $2,850.45/year
- Monthly clawback: $237.54
- Net OAS received: $727.67 - $237.54 = $490.13/month
Robert keeps some OAS but loses approximately 33% to the clawback.
Avoiding the Clawback
Strategies to minimize or avoid the clawback include:
- Income splitting with a spouse (if applicable)
- Deferring OAS to age 70 (reduces years of clawback)
- Timing RRSP withdrawals strategically
- Using TFSA for retirement savings (withdrawals not taxable)
- Managing taxable income in retirement
Guaranteed Income Supplement (GIS)
The GIS provides additional monthly payments to low-income OAS recipients.
GIS Eligibility
To qualify for GIS, you must:
- Be receiving OAS
- Have income below the maximum threshold
- Live in Canada
GIS Payment Amounts (January-March 2025)
| Situation | Maximum Monthly GIS |
|---|---|
| Single, widowed, or divorced | $1,026.40 |
| Spouse receives full OAS | $618.15 |
| Spouse does not receive OAS | $1,026.40 |
| Spouse receives GIS/Allowance | $618.15 |
Income Thresholds for GIS
GIS payments are reduced as your income increases. For a single person, GIS is fully phased out when income reaches approximately $21,000 (excluding OAS).
Deferring Your OAS Pension
You can delay receiving OAS to get a higher monthly amount later.
Deferral Benefits
For every month you defer OAS past age 65, your pension increases by 0.6%:
- Defer to age 66: 7.2% increase
- Defer to age 67: 14.4% increase
- Defer to age 68: 21.6% increase
- Defer to age 69: 28.8% increase
- Defer to age 70: 36% increase (maximum)
At age 70, your monthly OAS could be $989.63 (based on Jan-Mar 2025 rates for ages 65-74).
When to Consider Deferral
Deferral may be beneficial if:
- You have sufficient retirement income from other sources
- You expect to live a long life (break-even typically mid-80s)
- You want to reduce clawback during high-income years
- You are still working at age 65
How to Apply for OAS
Service Canada typically sends automatic enrollment letters to eligible seniors. However, you may need to apply if:
- You did not receive an automatic enrollment letter
- Service Canada has incomplete information about you
- You deferred your pension and now want to start it
Application Methods
- Online: Through your My Service Canada Account
- By Mail: Download and mail the application form
- In Person: At a Service Canada Centre
When to Apply
You can apply up to 11 months before you want your pension to start. Apply at least 6 months before your 65th birthday to ensure timely payment.
Taxation of OAS Benefits
OAS payments are taxable income that must be reported on your tax return.
Tax Withholding
You can request voluntary tax withholding from your OAS payments to avoid owing taxes when you file your return. Options include withholding:
- No tax (default)
- 10% tax
- 20% tax
Combined with Other Income
Your OAS is added to other income (CPP, RRIF withdrawals, pension income, employment income) and taxed at your marginal rate. Use our Canadian income tax calculator to estimate your total tax liability.
Old Age Security Programs Around the World
Canada's Old Age Security (OAS) is part of a global network of government-funded pension programs designed to provide income security for seniors. Each country takes a different approach to funding, eligibility, and benefit levels.
| Country | Program | Min Age | Funding Source | Max Monthly Benefit |
|---|---|---|---|---|
| Canada | Old Age Security (OAS) | 65 (or 70 deferred) | General tax revenues | ~$728-$800 CAD (2025) |
| United States | Social Security | 62 (reduced) / 67 (full) | Payroll taxes (FICA) | ~$3,822 USD/month (maximum, 2025) |
| United Kingdom | State Pension | 66 (rising to 67) | National Insurance contributions | ~£221.20/week (new state pension, 2024/25) |
| Australia | Age Pension | 67 | General government revenue (means-tested) | ~$1,116 AUD/fortnight (couple, 2025) |
| Germany | Gesetzliche Rentenversicherung | 63-67 (flex) | Payroll contributions (18.6% split) | Points-based; ~38% of prior earnings average |
| India | National Pension System (NPS) + Indira Gandhi National Old Age Pension | 60+ | Contributions + government subsidy | Very limited state pension; NPS market-linked |
Canada's OAS is funded through general tax revenue rather than payroll contributions, making it unique compared to contribution-based systems like CPP, US Social Security, or the UK State Pension. This design provides a universal safety net for seniors regardless of work history, though it is subject to a clawback for higher-income earners.
Frequently Asked Questions
For January-March 2025, the maximum monthly OAS payment is $727.67 for ages 65-74 and $800.44 for age 75 and over. These amounts are reviewed quarterly and indexed to inflation.
No, OAS is not based on employment history or contributions. It is funded through general tax revenues. You qualify based on your age (65+) and years of residency in Canada after age 18. You need 40 years in Canada for the full pension.
The OAS clawback (Recovery Tax) begins when your net income exceeds $90,997 (for 2024). You must repay 15% of the excess income. For example, if your income is $100,997, you repay 15% of $10,000 = $1,500. Full clawback occurs at $148,179 for ages 65-74.
Deferring OAS increases your monthly payment by 0.6% for each month deferred, up to 36% at age 70. This may be beneficial if you have other income sources, expect a long lifespan (break-even typically mid-80s), want to reduce clawback exposure, or are still working at 65. However, you give up 5 years of payments.
Yes, you can receive OAS outside Canada if you meet certain conditions. If you lived in Canada for 20+ years after age 18, you can receive OAS anywhere in the world. If less than 20 years, you can only receive OAS for 6 months outside Canada unless you return. Your payments continue but may be subject to withholding tax depending on the country.
The GIS is a monthly non-taxable benefit for low-income OAS recipients. As of January-March 2025, single seniors can receive up to $1,026.40/month in addition to OAS. The amount decreases as your income increases and phases out around $21,000 for singles. Unlike OAS, you cannot receive GIS while living outside Canada.
Most Canadians are automatically enrolled and receive a letter from Service Canada. If not automatically enrolled, apply online through your My Service Canada Account, by mail using the application form, or in person at a Service Canada Centre. Apply at least 6 months before turning 65 to ensure timely payment.
Yes, OAS payments are taxable income and must be reported on your tax return. They are added to your other income and taxed at your marginal rate. You can request voluntary tax withholding from your OAS payments (10% or 20%) to avoid owing tax at filing time. GIS, however, is non-taxable.
Starting the month after you turn 75, your OAS pension automatically increases by 10%. This is a permanent increase. For January-March 2025, this means your monthly payment increases from $727.67 to $800.44. No application is required - the increase is automatic.
No, unlike pension income splitting for tax purposes, OAS cannot be split with a spouse. Each person receives their own OAS based on their individual eligibility and years of residency. However, CPP and eligible pension income can be split, which may help manage your overall tax situation and reduce clawback exposure.
OAS and CPP are completely different programs. OAS is funded by general taxes, based on residency (40 years for full benefit), starts at 65, and is subject to clawback. CPP is funded by contributions you made while working, based on contribution history, can start at 60 (reduced) to 70 (increased), and is never clawed back. Most Canadians receive both.
Unlike CPP which has a dedicated fund, OAS is paid from general government revenues. While the program faces challenges with an aging population, it is considered sustainable through general taxation. The government periodically reviews OAS but there are no current plans to eliminate it. Changes to eligibility age (moved from 67 back to 65 in 2015) show the program evolves with political priorities.
Strategies to reduce clawback include: deferring OAS to age 70 (fewer years of clawback), income splitting with a spouse (pension splitting), using TFSA instead of RRSP/RRIF (TFSA withdrawals not taxable), timing RRIF withdrawals to stay under threshold, and managing capital gains realization. Consult a financial planner for personalized strategies.
If you have less than 40 years of Canadian residency after age 18, you receive a partial OAS pension. The formula is: Full pension × (Years in Canada ÷ 40). For example, with 30 years: $727.67 × 0.75 = $545.75/month. Years in countries with social security agreements may count toward the 40 years.
OAS payments are reviewed quarterly (January, April, July, October) and increased based on the Consumer Price Index to keep up with inflation. In recent years, payments have increased regularly. The 10% age 75 increase is permanent and applied on top of inflation adjustments.
