OAS Clawback Guide Canada 2026 | How to Avoid the Recovery Tax

What Is the OAS Clawback?

The Old Age Security Recovery Tax — universally known as the OAS clawback — is a mechanism that requires high-income seniors to repay some or all of their OAS pension. It exists because OAS is a universal benefit not tied to employment history, and the government limits the net cost by recovering it from recipients whose income exceeds a set threshold.

The mechanics are straightforward: for every dollar of net income above $90,997 in 2026, you must repay 15 cents of OAS. At roughly $148,451 of net income, the full annual OAS benefit has been clawed back entirely. For a senior receiving the full OAS of $727.67 per month, that represents the loss of up to $8,732 per year — a meaningful sum that makes income planning around this threshold genuinely worthwhile.

The clawback applies to your net income (Line 23600 on your T1 return), not your gross income or taxable income. This distinction matters because net income is affected by deductions like RRSP contributions, union dues, and — critically — pension income splitting. The strategies that work to reduce the clawback all operate by reducing your Line 23600 figure below $90,997.

For a quick numerical estimate of your clawback, use the OAS clawback calculator. This guide covers the full rules, the income traps to avoid, and the proven strategies for keeping more of your OAS.

2026 OAS Clawback Amounts by Income Level

The recovery tax is linear: every dollar above the threshold costs you exactly $0.15 in OAS. The table below shows the annual clawback and monthly OAS reduction at various income levels. These figures assume you receive the full OAS of $727.67 per month — if you deferred OAS to 70 for a 36% increase, your full elimination threshold is slightly higher because your annual OAS is larger.

Full elimination: $8,732 annual OAS ÷ 15% + $90,997 threshold ≈ $148,200.

A key implication of the linear structure is that a relatively modest income reduction can produce a disproportionately large benefit. If your net income sits at $105,000, you are losing $2,100 per year in OAS clawback. Reducing your net income by just $15,000 — perhaps through pension income splitting or TFSA substitution — eliminates the clawback entirely and restores your full OAS. The strategies below show how to make that reduction in practice.

Which Income Counts Toward the Clawback?

Not all income is created equal for OAS clawback purposes. The clawback is based on your net income (Line 23600), which follows specific CRA rules about what is included and excluded. Understanding this list is the foundation of any clawback avoidance strategy.

The Dividend Gross-Up Trap

One of the most common OAS clawback surprises involves Canadian dividends held in non-registered accounts. Eligible dividends are grossed up by 38% for tax purposes — meaning $20,000 of eligible dividends adds $27,600 to your net income, not $20,000. The dividend tax credit partially offsets the extra tax owed, but the inflated gross-up amount still counts in full for OAS clawback purposes. A retiree with $30,000 of eligible dividends outside a TFSA has an extra $11,400 of phantom income pushing toward the threshold.

The solution is straightforward: hold dividend-paying stocks inside a TFSA where the gross-up does not exist and the income is invisible to the clawback entirely. For retirees with large non-registered portfolios, this reallocation alone can be worth thousands of dollars annually in preserved OAS. The capital gains tax guide explains how realized gains are also reported on Line 23600 and why timing large dispositions matters.

Why TFSA Withdrawals Are the Most Powerful Tool

TFSA withdrawals do not appear anywhere on your tax return. They are not income, not a deduction, and have no interaction with OAS clawback or the GIS means test. A retiree who draws $20,000 from a TFSA instead of $20,000 from a RRIF reduces their net income by $20,000 — potentially keeping $3,000 in annual OAS that would otherwise be clawed back. This is why maximizing TFSA contributions during your working years pays a dividend that is difficult to replicate through any other strategy.

Pension Income Splitting to Reduce the Clawback

If you are 65 or older and receive RRIF income (or other eligible pension income), you can allocate up to 50% of that income to your spouse or common-law partner on your tax return using Form T1032. No money actually changes hands — the allocation is a paper entry that reduces your Line 23600 and increases your spouse’s. If your spouse has lower net income than you, the household tax bill falls and, critically, your personal net income may drop below the OAS clawback threshold.

This is one of the most effective clawback reduction tools available, and it requires no advance setup — just filing Form T1032 at tax time each year.

In the first scenario, shifting $30,000 of RRIF income to a spouse with $40,000 of income brings the higher earner’s net income to $90,000 — just under the $90,997 threshold — and eliminates $4,350 in annual clawback. That is $4,350 per year, every year, for no cost beyond the paperwork. For couples with a meaningful income gap, pension income splitting should be reviewed each year at tax time.

The RRSP Meltdown Strategy: The Most Powerful Long-Term Fix

For Canadians who have not yet reached age 71, the most effective long-term clawback management strategy is deliberately drawing down RRSP balances during the years before mandatory RRIF conversion. This is sometimes called the “RRSP meltdown” strategy, and it can dramatically reduce OAS clawback exposure for the remainder of retirement.

Here is the logic: at age 71, CRA requires you to convert your RRSP to a RRIF. The RRIF then imposes mandatory minimum withdrawals every year — percentages that increase with age — applied to whatever balance exists at January 1. If you retire at 62 and leave your RRSP untouched for nine years, the balance grows substantially. By age 72, the mandatory minimum might force $30,000–$60,000 or more in annual RRIF income on top of CPP and OAS, pushing you well past the clawback threshold for the rest of your life.

The alternative is to voluntarily withdraw from the RRSP in your 60s — ideally in years when your income is low — and reinvest the after-tax proceeds in your TFSA.

The tax cost of voluntary RRSP withdrawals in a low-income year — say, $20,000 withdrawn when total income is $40,000 — is modest. The long-term benefit is a smaller RRIF balance, lower mandatory minimums, and potentially decades of reduced OAS clawback. For detailed sequencing, the RRSP to RRIF conversion guide and RRSP withdrawal tax calculator are the right tools.

Full Strategy Summary

Several strategies can reduce the OAS clawback, either by lowering your net income directly or by restructuring which accounts you draw from. The table below summarizes the main options and their approximate impact for someone currently losing $2,000–$4,000 per year in clawback.

No single strategy works in isolation — the most effective approach combines two or three of the above. A retiree who pension-income-splits with their spouse, holds dividend ETFs in a TFSA, and draws on the TFSA before making extra RRIF withdrawals can often keep their full OAS even at income levels that initially appear to exceed the threshold by $15,000–$25,000.

How CRA Administers the Clawback Year to Year

The clawback is not simply a line on your tax return — it affects your actual monthly OAS cheque in the following year. Understanding the two-stage administration process helps you avoid cash flow surprises.

Stage one — tax filing: When you file your T1 return, you report all OAS income on Line 11300. If your net income exceeds $90,997, you calculate the recovery tax and report it on Line 23500 as an OAS repayment deduction. This simultaneously reduces your net income (useful for other income-tested calculations) and represents the amount you owe back to the government. Your T4A(OAS) slip will show both the OAS received and the repayment amount.

Stage two — prospective withholding: Based on your prior-year income, Service Canada automatically reduces your monthly OAS payments beginning the following July. If your 2025 net income was $110,000, your OAS cheque from July 2026 onward will be reduced by approximately $238 per month until June 2027. You are not double-paying — the monthly reduction replaces the lump-sum repayment at filing.

If your income drops significantly in the current year — due to retirement, a one-time capital gain that will not recur, or a business sale — your monthly OAS will still be reduced based on last year’s high income. You can apply to Service Canada using Form ISP-3520 to waive the withholding reduction. Without this form, you will receive reduced OAS during a year when you may not need to repay any clawback at all, and wait for a refund at the following year’s filing.

The Bottom Line

The OAS clawback starts at $90,997 of net income in 2026 and eliminates OAS entirely above approximately $148,000. Because the clawback rate is a flat 15 cents per dollar, even a modest reduction in net income produces a direct and immediate benefit in preserved OAS.

TFSA withdrawals are the single most powerful clawback management tool because they are completely excluded from net income — reducing RRIF withdrawals dollar-for-dollar by drawing on TFSA instead cuts the clawback proportionally. Combined with pension income splitting, a deliberate RRSP meltdown strategy before age 71, and thoughtful timing of capital gains and dividend income, many Canadians who initially appear exposed to significant clawback can preserve their full OAS benefit through retirement.

The planning is not complicated — it mostly requires awareness of Line 23600, an understanding of which income is invisible to the clawback, and a willingness to adjust the sequencing of account withdrawals each year. The OAS clawback calculator lets you model your specific situation and test the impact of each strategy.
