OAS Clawback: How Margaret Stopped Losing 15 Cents of Every Extra Dollar

The benefit you can lose without noticing

Margaret is 68, retired and living in Victoria, and on paper she had a comfortable retirement income. What she did not realize was that part of her Old Age Security was leaking away every year, recovered by the government through a mechanism most retirees barely understand until it hits them: the OAS clawback.

She found out almost by accident, reviewing her tax return, when she noticed an OAS recovery amount she could not explain. "I had earned that benefit," she said. "Why was I giving some of it back?"

It is a remarkably common surprise. OAS is not deducted at source the way employment income tax is, so the recovery often shows up quietly as a line on the tax return or as a reduction in next year's payments. Many retirees never connect that reduction to the choices that caused it. They just notice their OAS cheque got smaller and assume there is nothing to be done. Margaret nearly made the same assumption — until she realized the size of her benefit was not fixed fate, but something her own income decisions were quietly steering.

How the OAS recovery tax works

Old Age Security is one of Canada's foundational retirement benefits, but it is income-tested at the top end. Here is the public rule. Once your net income for the year rises above a threshold the CRA sets annually, you must repay part of your OAS — 15 cents for every dollar of income above that threshold. This repayment is officially called the OAS recovery tax, and almost everyone calls it the clawback.

The cruelty of it is in that 15-cent figure. For income in the clawback zone, every extra dollar you earn does not just get taxed at your normal rate — it also costs you 15 cents of OAS on top. The combined effect can mean that an extra dollar of income is worth far less than you would expect, because two different bites are taken out of it at once.

"Once I understood it was 15 cents on top of regular tax," Margaret said, "I finally understood why earning a little more never seemed to help."

Margaret's situation

Margaret was sitting just above the threshold — not by a lot, but enough that a meaningful slice of her OAS was being recovered each year. The frustrating part was that her income was only barely over the line. A modest amount of careful reshaping could potentially get her back under it, or at least much closer, and stop the leak.

This is the situation where reshaping pays off most. If your income is far, far above the threshold, the clawback may recover your OAS entirely and there is little to be done about that particular benefit. But Margaret was perched right at the edge — and at the edge, small moves have outsized effects. Shaving a relatively modest amount off her net income did not just reduce the clawback proportionally; for her, it had the potential to switch much of it off. Being close to the line cuts both ways: it is easy to slip over, but it is also easy to step back under, if you know which lever to pull.

The key realization was that not all income counts the same way. Some sources land in the net income figure that drives the clawback; others, like withdrawals from a TFSA, do not show up there at all. That distinction is the lever.

This is the part that surprises people most. We tend to think of retirement income as one big pool — money is money. But to the clawback formula, a thousand dollars pulled from a RRIF and a thousand dollars pulled from a TFSA are completely different animals. The first adds to the net income that can cost you OAS; the second is invisible to it. Once Margaret saw her income that way — not as a single number but as a mix of ingredients, each with its own tax personality — the path forward stopped feeling like a sacrifice and started feeling like a recipe she could adjust.

Reshaping the source and timing of income

Margaret used TrackMoola's CPP and OAS tool to see how her benefit responded as she changed where her income came from and when she drew it. She did not change her lifestyle or how much she spent — she changed the composition of the income that funded it.

The comparison pointed toward a few moves that, together, eased her under the pressure point: leaning more on her TFSA for the income that was tipping her over, and rethinking the timing of some of her other withdrawals so that her net income in any single year stayed lower. TrackMoola did not prescribe the mechanics; it let her see how much OAS she kept under each arrangement, and the right shape became obvious.

Measure	Before reshaping	After reshaping
Net income vs. OAS threshold	Above the line	Back near or below it
OAS recovered by the CRA	A meaningful slice each year	Little to none
OAS kept per year (illustrative)	Baseline	About $2,500 more

For Margaret's situation, reshaping her income put roughly $2,500 a year of Old Age Security back in her pocket — benefit she had earned and was no longer handing back. Over a long retirement, a recurring annual amount like that adds up to a great deal. These figures are illustrative; they describe Margaret's circumstances, not yours.

Why the timing matters as much as the amount

One subtlety worth drawing out: the clawback is assessed on a single year's net income. That means a one-time spike — selling an asset, taking an unusually large withdrawal, or bunching income into one calendar year — can push you over the line for that year even if your income is otherwise modest. Spreading income more evenly across years, or sourcing it from accounts that do not feed the net income figure, can keep you out of the recovery zone. It is often less about earning less and more about smoothing and choosing the source.

Margaret learned this the practical way. She had been planning a larger-than-usual withdrawal to help one of her children with a down payment, all in a single year. Before, she would have simply taken it and never connected the dots. Looking at the effect in TrackMoola's CPP and OAS tool, she could see that bunching it into one year would have spiked her net income and clawed back a chunk of OAS on top of the regular tax. Splitting the help across two calendar years, and drawing part of it from her TFSA, kept her under the threshold both years. Same generosity to her child, far less lost to the recovery tax — purely a question of timing and source.

A word on what it is not

It is worth being clear that none of this is about hiding income or gaming the system. Every dollar Margaret drew was reported exactly as it should be; she simply chose, within the ordinary rules, which accounts to draw from and when. The clawback is a feature of how OAS is designed, and arranging your affairs sensibly around it is no different from claiming a deduction you are entitled to. Margaret was not avoiding anything she owed — she was keeping a benefit she had earned and was entitled to keep.

She found that framing genuinely freeing. For a while she had felt a vague unease, as though trying to keep her full OAS was somehow unseemly. But OAS is a benefit Canada deliberately provides to retirees, with an income test built into its design. Working within that design is simply being an informed citizen, no different from a younger Canadian timing a TFSA contribution or claiming child-care expenses. Once Margaret let go of the guilt, she could focus on the practical question that actually mattered: how to arrange her income, year by year, so that more of the benefit stayed where it belonged.

What her story illustrates

• OAS is clawed back at 15 cents per dollar of net income above the CRA's annual threshold.
• In the clawback zone, an extra dollar of income costs you regular tax plus 15 cents of OAS — a double bite.
• Not all income counts toward the clawback the same way; TFSA withdrawals, for instance, do not feed net income.
• Because it is assessed year by year, smoothing income and avoiding one-year spikes can preserve your benefit.

Try it yourself

If you are over 65 and your income is anywhere near the OAS threshold, it is well worth checking whether you are quietly giving some of your benefit back. Try your own numbers in TrackMoola's CPP and OAS tool and see how much OAS you keep as you adjust where your income comes from and when. Like Margaret, you may find that a little reshaping recovers money you did not know you were losing.
