Because this clawback is based on net income (Line 23600 of your tax return), it is triggered by standard retirement income sources like mandatory Registered Retirement Income Fund (RRIF) withdrawals, corporate dividends, and even capital gains on investment properties. If you do not plan your withdrawal order carefully, you will face an effective marginal tax rate of over 50%.
Understanding the 2026 OAS Clawback Thresholds
The OAS clawback operates on a simple scale: for every dollar your net income exceeds the annual threshold, you must repay 15 cents of your OAS pension. This repayment is clawed back directly from your monthly OAS deposits during the next benefit cycle (running from July to June of the following year).
For the 2026 tax year, the clawback threshold is set at $90,997.
This means if your net income is below $90,997, you receive your full OAS payment. Once your net income exceeds this amount, your pension is reduced. If your net income reaches roughly $148,000 (depending on your exact age and the matching pension indexation), your OAS benefit is clawed back completely to $0.
For official verification of these thresholds, review the Government of Canada OAS benefit tables.
Worked Example: How the Clawback Math Impacts Your Monthly Cash Flow
Let's look at Sarah, a 68-year-old retired nurse living in Ontario. She has structured her retirement income around a few different streams:
- Canada Pension Plan (CPP): $14,000 per year
- Defined Benefit (DB) pension from her career: $42,000 per year
- Mandatory minimum RRIF withdrawal: $18,000 per year
- GIC interest and taxable stock dividends: $15,000 per year
- Base OAS pension: $8,500 per year
When Sarah files her taxes, her total net income (excluding OAS itself for clawback calculation purposes, but including other taxable items) is:
$14,000 + $42,000 + $18,000 + $15,000 = $89,000.
When we add her OAS pension, her total income is $97,500. For the clawback calculation, the CRA looks at her net income of $97,500 (since OAS is included in net income on Line 23600).
The Calculation:
- Calculate the excess income over the threshold: $97,500 - $90,997 = $6,503
- Calculate the annual clawback amount (15%): $6,503 * 0.15 = $975.45
- Calculate the monthly reduction: $975.45 / 12 = $81.29 per month
Starting in July of the following year, Sarah's monthly OAS check will be reduced by $81.29. Instead of receiving her full base monthly payment of roughly $708, she will only receive $626.71.
The Five Rules for OAS Clawback Avoidance
Avoiding the clawback requires managing your taxable income. Here are the five most effective tax bracket optimization strategies to protect your OAS:
1. Use Pension Income Splitting
If you are married or in a common-law relationship, you can allocate up to 50% of your eligible pension income to your spouse for tax purposes. Eligible income includes Defined Benefit pension payments and RRIF withdrawals (after age 65).
In Sarah's case, if her spouse has no pension income, she can split her $42,000 DB pension and $18,000 RRIF withdrawal, transferring $30,000 of taxable income to her spouse. This brings her personal net income well below the $90,997 threshold, saving her full OAS benefit.
2. Run a "RRIF Meltdown" Strategy Before Age 65
Most Canadians wait until age 71 to convert their RRSPs to RRIFs. But if you have a large RRSP, the mandatory minimum withdrawals starting at age 72 will be huge. This forced income can easily push you into the OAS clawback zone.
To avoid this, draw down your RRSPs early (between ages 60 and 64, before your OAS starts). By melting down your RRSP early, you pay tax now, but you reduce the future size of your RRIF. This keeps your future mandatory withdrawals small enough to avoid the clawback later. Read more details in our RRIF Minimum Withdrawal Guide.
3. Delay Your OAS Pension to Age 70
You can start collecting OAS at age 65, or you can delay it up to age 70. For every month you delay, your pension increases by 0.6% (or 7.2% per year). If you delay to age 70, your pension will be 36% larger.
If you are working or consulting between ages 65 and 69, your high income will likely claw back your OAS entirely. By delaying OAS to age 70, you avoid wasting the benefit during your high-income years. Once you stop working at 70 and your income drops, you can collect a much larger, clawback-free pension.
4. Prioritize TFSA Contributions Over Taxable Accounts
Interest from GICs and dividends from taxable stock accounts are included in net income. However, withdrawals from a Tax-Free Savings Account (TFSA) are completely exempt from tax and do not count toward your net income for OAS calculations.
If you need extra cash, withdraw it from your TFSA rather than selling taxable investments that generate capital gains or interest. Model these options using the Retirement Calculator at CalculatorVillage to see the long-term impact on your assets.
5. Corporate Tax Planning for Business Owners
If you own a Canadian Controlled Private Corporation (CCPC), do not pay yourself large taxable dividends in retirement if it will trigger the OAS clawback. Keep excess cash inside the corporation, or use corporate holdings to fund your retirement lifestyle in a tax-efficient way.
Summary of Avoidance Strategies
| Strategy | How It Works | Best For |
|---|---|---|
| Pension Splitting | Transfer up to 50% of pension income to a lower-income spouse. | Couples with unequal pension incomes. |
| RRIF Meltdown | Withdraw RRSP funds early to reduce future mandatory RRIF minimums. | Retirees with large RRSPs ($300k+). |
| Delaying OAS | Postpone OAS start date to age 70 for a 36% larger monthly payment. | Seniors working or consulting between ages 65 and 69. |
| TFSA Withdrawals | Use TFSA funds to supplement income without adding to taxable net income. | Retirees who have accumulated significant TFSA room. |
Frequently Asked Questions
Does selling a house trigger the OAS clawback?
If the house is your principal residence, the capital gains are tax-exempt (using the Principal Residence Exemption) and will not affect your OAS. However, if you sell an investment property or cottage, the taxable portion of the capital gain will count toward your net income and can trigger a clawback for that year.
Is the OAS clawback based on individual or household income?
The OAS clawback is based strictly on your individual net income. Your spouse's income does not affect your clawback calculation, though you can use pension income splitting to balance your individual incomes.
Can I request a waiver for the OAS clawback if my income drops?
Yes. If you experience a sudden drop in income (for example, if you retire or stop consulting), you can file Form T1213(OAS) to request that the CRA reduce the recovery tax deducted from your monthly payments.
