Many Canadians spend decades building retirement income through pensions, RRSPs, TFSAs, dividend stocks, ETFs, and sometimes rental properties. Once Old Age Security starts at 65, some of that income can create an unexpected problem: the OAS clawback. You did the right things, you saved, you diversified, and then a chunk of your OAS gets reduced because your taxable income looks higher than it feels.
This article is the OAS clawback explained in plain language. You will learn what triggers it, which income sources count, and how thoughtful account planning can reduce surprises. It is a rule to plan around, not an emergency to react to.
What Is the OAS Clawback?
The OAS clawback is a rule that can reduce your OAS payments when your income is high enough. The government’s official name is the OAS pension recovery tax, often shortened to “recovery tax.” It applies when your net income before adjustments, reported on your tax return, is over a yearly threshold.
How the OAS Recovery Tax Works
In plain language, if your income is over the threshold, you repay 15% of the amount above it. The repayment is usually spread out through the year as a reduction in your monthly OAS payments, so the impact shows up quietly rather than all at once.
The threshold changes over time
The OAS income threshold is indexed annually. The Government of Canada publishes a table showing the minimum threshold (where the clawback begins) and the maximum (where OAS is fully clawed back). Recent figures:
- 2024 income (OAS July 2025 to June 2026): starts at $90,997
- 2025 income (OAS July 2026 to June 2027): starts at $93,454
- 2026 income (OAS July 2027 to June 2028): starts at $95,323
It’s based on your tax return, not your bank account
For Canadians living in Canada, OAS repayment is tied to net income before adjustments (line 23400). Cash you withdraw from taxable sources, like a RRIF or a non-registered account, usually raises that number. Cash you withdraw from a TFSA does not.
Quick example
If your 2024 net income before adjustments was $98,000 and the 2024 threshold was $90,997, the calculation is $98,000 minus $90,997, which is $7,003. That amount multiplied by 15% comes to about $1,050 repaid through reduced OAS over the year.
Which Types of Retirement Income Count?
A useful rule of thumb: if it shows up as taxable income, it can increase OAS clawback risk. Common sources include CPP, workplace pensions, RRSP and RRIF withdrawals, interest from GICs and bonds, eligible Canadian dividends, foreign dividends, capital gains from non-registered accounts, and rental income. All of these flow into line 23400.
How Dividends, Interest, and Capital Gains Affect OAS
Investment income is often the biggest variable for self-directed Canadian retirees. It is also where surprises happen.
Interest income (often the “highest impact”)
Interest from GICs, bonds, and savings is generally fully taxable, so it can push net income higher dollar for dollar. If you are close to the OAS income threshold, a large GIC ladder in a non-registered account can raise clawback exposure faster than many investors expect.
Eligible Canadian dividends (watch the gross-up)
Eligible dividends can be tax-efficient, but they come with a wrinkle. On your tax return they are grossed up, so the reported figure is higher than the cash received. A common example is a 38% gross-up: $100 of eligible dividends may be reported as $138 of income. Red flag: if your reported dividend income trends near the threshold, the gross-up alone can be the difference between full OAS and clawback territory. That is why “dividend income and OAS clawback” is a common pain point.
Foreign dividends (usually fully taxable, plus withholding)
Foreign dividends, including U.S. dividends, are generally taxed like regular income in a taxable account, and U.S. dividends often face withholding tax. The cleanest place to hold them is usually inside an RRSP, where U.S. withholding is typically exempt on direct U.S. dividends.
Capital gains (only part is taxable, but timing matters)
Capital gains are more flexible because you control when you sell. Only the taxable portion is included in income, but a large one-time sale, like rebalancing a concentrated position, can still create a clawback year.
TFSA, RRSP, and RRIF Planning Basics
This is where taxable income retirement planning becomes real. The accounts you use can change your OAS result.
TFSA and OAS clawback
TFSA withdrawals do not count as taxable income. That means TFSA cash flow can fund retirement spending without raising the number that drives any clawback. If you need an extra $10,000 for a car or home repair, pulling it from a TFSA is usually cleaner than from a RRIF or a taxable account.
RRSP withdrawals and OAS
RRSP withdrawals are taxable. Many investors wait until mandatory RRIF withdrawals start and then feel stuck with higher taxable income later in retirement. A common planning idea, though not one-size-fits-all, is gradual RRSP withdrawals before age 72, especially in years where taxable income is temporarily lower.
RRIF withdrawals and OAS
Once you convert to a RRIF, minimum withdrawals begin and can push taxable income up even if you do not need the cash. That is why “RRIF withdrawals and OAS” is such a hot topic. The RRIF minimums can force higher taxable income later, which increases clawback exposure.
How Canadian Investors Can Reduce OAS Clawback Surprises
This section is about being practical, not perfect. The goal is not always to avoid clawback at all costs. Sometimes earning more, even with some clawback, still leaves you ahead.
Estimate your retirement income before age 65
Before OAS starts, sketch a simple income map: CPP, OAS, pensions, expected RRSP and RRIF withdrawals, taxable interest and dividends, planned capital gains, and rental income. If that total sits near the OAS income threshold, you have found your planning zone.
Use TFSA withdrawals strategically
A TFSA acts like a pressure release valve. In a year that already looks high, TFSA withdrawals for discretionary spending help you avoid stacking more taxable income on top.
Consider smoothing RRSP withdrawals before RRIF conversion
Waiting until RRIF minimums begin can create a sharp jump in taxable income. A smoother approach: planned RRSP withdrawals in your late 60s, topping up TFSA room if available, and avoiding spikes later.
Balance dividend income with capital gains (and watch the dividend gross-up)
Dividend investing can be a solid strategy. Remember that eligible dividends in a non-registered account report higher income due to the gross-up, while capital gains give you more timing control. Many retirees aim for a mix for flexibility year to year.
Review your taxable income before year-end
If you are close to the threshold, small timing decisions can matter. Selling in December versus January, taking an extra RRIF withdrawal this year versus next, or realizing gains in a lower-income year can change the outcome.
When to Speak With a Tax Professional
OAS clawback planning is best tailored to the individual. The right approach depends on your province, your mix of TFSA, RRSP, RRIF, and taxable accounts, pension splitting opportunities, corporate investments, and one-time income events like selling a property. This article is educational, not personal tax advice. If you are within a few thousand dollars of the threshold, or expect a big income year, it is worth getting tailored help.
Conclusion: Plan for OAS Like You Plan for Income
OAS clawback is driven by Canadian retirees income tax mechanics, not portfolio size. The discipline is to plan withdrawals in advance rather than react in March when the slips arrive. With smart account structure, especially thoughtful TFSA use and controlled RRSP and RRIF withdrawals, you reduce surprises and stay in control. Used well, that patience protects both your OAS and the capital that has to fund the next 20 to 30 years.
