The OAS clawback — officially called the Old Age Security (OAS) Recovery Tax — reduces or eliminates your monthly OAS pension if your net income exceeds a threshold set by the federal government each year. For 2025, the OAS clawback threshold is $90,997. For every dollar your net income exceeds this threshold, CRA claws back 15 cents of your OAS — meaning your OAS is completely eliminated when your net income reaches approximately $148,000. Understanding how the OAS clawback works and how to legally reduce your net income to minimize or avoid it is a critical retirement tax planning strategy.

How the OAS Clawback Works — The Numbers

Maximum OAS pension (2025): For seniors who turned 65–74, the maximum OAS is $727.67/month = $8,732/year. For seniors 75+, it is $800.44/month = $9,605/year (enhanced by 10% starting July 2022).

What Income Counts for the OAS Clawback?

The OAS clawback is based on your net income (line 23600 of your T1 return), which includes:

• Employment income (full-time, part-time, consulting)
• CPP and other pension income
• RRSP and RRIF withdrawals
• Rental income (net of expenses)
• Taxable capital gains (50% included — or 66.67% on gains over $250,000 after 2024)
• Investment income (dividends, interest)
• Business income (self-employment)
• Foreign pension income

Crucially, TFSA withdrawals are NOT included in net income — they are completely excluded from the OAS clawback calculation. This is the primary reason that maximizing your TFSA in pre-retirement years is so important for OAS preservation.

5 Legal Strategies to Reduce the OAS Clawback

Strategy 1: Maximize TFSA Withdrawals Instead of RRIF Withdrawals

The most powerful OAS clawback reduction strategy: draw retirement income from your TFSA (which has no impact on net income) instead of forcing additional RRIF withdrawals beyond the mandatory minimum. Even converting $20,000 of planned RRIF withdrawals to TFSA withdrawals reduces net income by $20,000 — eliminating $3,000 of annual OAS clawback (15% × $20,000). Over a 20-year retirement, this single strategy preserves $60,000+ of OAS. Our TFSA contribution guide explains how to maximize your TFSA room leading up to retirement.

Strategy 2: Pension Income Splitting with Your Spouse

If you have a spouse or common-law partner, you can split up to 50% of eligible pension income (RRIF withdrawals, defined benefit pension, QPP/CPP after age 65) with them on your tax returns. If your income is above the OAS clawback threshold and your spouse’s income is below it, transferring pension income to your spouse can bring your net income below $90,997 — restoring your full OAS. Example:

• Your net income before splitting: $115,000 — OAS clawback: $3,600
• Transfer $25,000 RRIF income to spouse
• Your net income after splitting: $90,000 — below $90,997 threshold — OAS clawback: $0
• Annual OAS saved: $3,600/year = $72,000 over a 20-year retirement

Strategy 3: Defer OAS Itself to Age 70

You can defer starting your OAS pension from age 65 to as late as age 70. For each month you defer beyond age 65, your OAS increases by 0.6% (7.2% per year). Deferring to age 70 increases your OAS by 36%. The benefit of deferral: if your income between ages 65–70 is above the clawback threshold anyway (you’re still working or taking large RRIF withdrawals), you lose the OAS to clawback in those years regardless. Deferring means you receive a larger OAS starting at 70 — when your income may be lower and the clawback doesn’t apply. OAS deferral is particularly effective if you expect your income to drop significantly between ages 65 and 70.

Strategy 4: Strategic Capital Gains Timing

Capital gains realized in any year increase your net income and can push you over the OAS clawback threshold. Strategies to reduce capital gains impact:

• Spread large capital gains over multiple years rather than realizing them all in one year (requires advance planning for asset sales)
• Use capital losses to offset gains: Harvest capital losses before December 31 to offset capital gains in the same year. See our tax loss harvesting guide
• Hold investments generating capital gains inside the TFSA — gains in the TFSA never appear in net income
• Delay asset sales to a year when other income is lower (lower RRIF year, lower employment income)

Strategy 5: RRSP Contributions in Working Years — Deductions Reduce Future Clawback Years

Every dollar you contribute to an RRSP reduces your taxable income in the contribution year. This delays your tax liability to retirement — but if you plan your RRSP/RRIF drawdown carefully to stay below the OAS threshold, you can come out significantly ahead. The optimal pre-retirement RRSP strategy for OAS preservation:

• Maximize RRSP contributions during your peak earning years (reducing income NOW at 43%+ marginal rate)
• Convert RRSP to RRIF by age 71 (required)
• Draw down RRIF strategically — take only the mandatory minimum or slightly more in early RRIF years to keep RRIF balance low by the time OAS kicks in
• Supplement RRIF income with TFSA withdrawals (no net income impact) to manage the OAS clawback

OAS Clawback and RRSP Meltdown Strategy

The “RRSP meltdown” is a strategy where retirees strategically draw down their RRSP before age 71 (when conversion to RRIF is mandatory) at lower tax rates — to avoid the OAS clawback later. The logic:

• If you retire at 60–65 and your income is temporarily low, you can draw RRSP funds at lower marginal rates (20–30%) before OAS begins at 65
• You invest the after-tax proceeds in your TFSA (sheltering future growth from net income)
• By the time OAS starts, your RRIF balance is smaller — reducing your mandatory RRIF withdrawals below the OAS clawback threshold

This strategy requires careful modelling of lifetime income, tax rates, and clawback exposure. Our estate planning accountant team provides personalized RRSP/RRIF/TFSA drawdown planning for Mississauga retirees.

Frequently Asked Questions

What is the OAS clawback threshold for 2025?

The OAS clawback (OAS Recovery Tax) threshold for the July 2025 to June 2026 payment period is $90,997 of net income (based on 2024 income reported on your 2024 T1 return, filed in April/June 2025). For every dollar of net income above $90,997, you repay 15 cents of OAS. Your OAS is completely eliminated at a net income of approximately $148,179 for 2025. The threshold increases each year with inflation indexing. Call Pathak Professional Corporation at 437-872-7399 to model the exact impact of the 2025 clawback threshold on your retirement income plan.

How does CRA collect the OAS clawback?

CRA administers the OAS clawback in two ways: First, if CRA estimated that your income for the current year will exceed the threshold (based on prior year income), it reduces your monthly OAS payments throughout the year (called “direct recovery”). Second, after you file your T1 return, CRA reconciles the actual clawback amount and either assesses additional recovery tax or refunds any excess reduction. The OAS clawback is reported on Schedule 7 (OAS Recovery Tax) of your T1 return. If your 2024 income triggered a clawback, you will see reduced OAS payments starting July 2025.

Is there a way to defer the OAS clawback to the next year?

If you receive a large one-time income item (a business sale, a large RRSP withdrawal, a capital gain) that pushes you over the OAS threshold in a single year, you cannot defer the clawback itself — the excess income in that year triggers the recovery tax. However, you can manage single-year income spikes through strategic planning BEFORE the income is realized: use capital losses to offset gains, spread income over multiple years (installment sales), use the lifetime capital gains exemption for qualifying property, or use your spouse’s lower income bracket through pension income splitting. Planning before the income event is always more effective than reacting after. Call Pathak Professional Corporation at 437-872-7399 to plan before a major income event.

Does the OAS clawback affect CPP as well?

No — the OAS clawback applies only to Old Age Security (OAS), not to Canada Pension Plan (CPP) benefits. CPP is a contributory pension based on your lifetime CPP contributions and is not subject to a clawback regardless of your income level. However, both CPP and OAS payments are included in your net income — which means CPP income itself can contribute to pushing your net income above the OAS clawback threshold. This is why managing all retirement income sources together (CPP timing, OAS timing, RRIF withdrawals, TFSA drawdowns) through integrated retirement tax planning is essential for Ontario retirees.
