OAS Clawback 2026: Thresholds, Brackets, and How Canadians Can Legally Avoid It

If your retirement income is heading north of $93,000 a year, the Canada Revenue Agency will quietly start taking back 15 cents of every extra dollar through the Old Age Security recovery tax. Most Canadians find out the hard way, after a T4A(OAS) slip lands in February. This 2026 guide walks through the exact thresholds, the math at each income level, and seven legal strategies that can keep tens of thousands of OAS dollars in your pocket over a long retirement.

What the OAS clawback actually is

The Old Age Security recovery tax, almost always called the OAS clawback, is an extra 15% tax the federal government applies to every dollar of net world income above a yearly threshold. It is collected through your tax return on line 23500, then prorated against your July-to-June OAS payment cycle. The CRA does not view it as a benefit cut; legally, it is an additional income tax on higher-income seniors that happens to be calibrated to your OAS.

The number that matters is on line 23600 of your T1 return: net world income. It includes employment, self-employment, CPP, OAS itself, RRIF withdrawals, taxable investment income, capital gains, foreign pensions, and rental income. TFSA withdrawals, the principal-residence portion of a home sale, and the non-taxable half of capital gains do not count.

2026 OAS clawback thresholds: the two numbers you need

CRA publishes two thresholds each year because the OAS payment cycle and the tax year do not line up. For 2026, the numbers Canadians actually need are:

The exact full-clawback ceiling moves quarterly with OAS indexation, but $155,000 to $161,000 is the right ballpark for planning. If your projected 2026 net income sits anywhere between $93,454 and $161,000, you are in the bracket and every planning lever in this article applies to you.

How much OAS will you actually lose? The 15% bracket in dollars

The marginal cost of an extra dollar of income inside the clawback bracket is your normal marginal tax rate plus 15%. For a typical Ontario or BC retiree in the high 20s for federal-provincial tax, that means roughly 45 to 50 cents per dollar of additional income. Below are realistic 2026 numbers for a 70-year-old receiving the standard age 65-74 OAS amount of about $8,800 per year.

Strategy 1: Split eligible pension income with your spouse

Up to 50% of eligible pension income (defined benefit pensions, RRIF withdrawals after age 65, certain annuity payments) can be allocated to your spouse on Form T1032 at tax time. Because the OAS threshold is per person, splitting can pull both partners under $95,000 and eliminate the clawback for the higher-earning spouse entirely. CPP cannot be split through T1032 but CPP sharing through Service Canada is a separate, similar lever.

Strategy 2: Use your TFSA as the late-life income source

TFSA withdrawals are not reported on line 23600 at all. A retiree with $250,000 inside a TFSA can withdraw $20,000 a year without moving the OAS clawback needle by a single dollar. The room comes back the following calendar year, and there is no minimum withdrawal. Over a 20-year retirement, deliberately filling the TFSA before age 65 is one of the highest-value clawback shields available.

Strategy 3: Start RRIF withdrawals earlier than required

The CRA forces you to convert RRSPs to RRIFs by December 31 of the year you turn 71, with minimum withdrawals beginning the next year. By age 80 the minimum is 6.82%, by 90 it is 11.92%. Those forced withdrawals push net income up fast, often straight into the clawback bracket. Drawing smaller voluntary amounts from the RRSP between 60 and 71 spreads taxable income across more low-bracket years and keeps later RRIF balances (and minimums) smaller.

Strategy 4: Defer OAS itself to age 70

Each month you delay OAS past 65 adds 0.6% to the eventual payment, capped at 36% extra if you defer all the way to 70. The bigger benefit moves the clawback threshold higher in real terms for your specific situation, because the recovery tax is calculated on a base that is now 36% larger. Deferral makes the most sense when you have a clear plan to draw down RRSPs or non-registered assets in the gap years.

Strategy 5: Optimise where you hold each asset

Asset location can reduce the line-23600 footprint of the same overall portfolio. Interest-heavy holdings (HISA ETFs, GICs, bonds) generate fully taxable income that goes straight to your clawback calculation, so they belong inside the RRSP or TFSA. Canadian equity ETFs are tax-friendly outside registered accounts because of the dividend tax credit and lower effective rate on capital gains. A rebalancing tool like Wealth Rebalancer makes it easier to see which sleeve sits where before you place your next trade.

Strategy 6: Realise capital gains in non-clawback years

If you have unrealised gains in a non-registered account and a year where your net income is well below $93,454 (say, the year you retire mid-cycle), triggering some gains then can be far cheaper than letting them compound and emerge during high-RRIF years. Only 50% of capital gains count toward net income, but in the wrong year that still pushes a moderate-income retiree into the clawback bracket.

Strategy 7: Beware the dividend gross-up trap

Eligible Canadian dividends get a 38% gross-up on your tax return before the dividend tax credit is applied. The gross-up amount is what hits line 23600, so $10,000 of actual dividends shows up as $13,800 of net income. Retirees with large non-registered Canadian dividend portfolios are routinely shocked by how aggressively this stacks against the OAS threshold. It is not a reason to avoid dividends, but it is a reason to be precise about which account holds them.

When the clawback is not worth fighting

If a planning move costs more than it saves, or forces a worse asset mix on you for a decade to dodge a few hundred dollars of recovery tax, do not bother. Above roughly $155,000 of net income you have already lost the full OAS, so the marginal cost of each extra dollar drops back to your normal tax bracket. The pain band sits firmly between $93,454 and about $135,000, where every dollar matters and small structural moves return outsized lifetime benefit.
