OAS Clawback in Canada: What Retirees Need to Know

OAS Clawback in Canada: Why the Wrong Income Strategy Costs You Twice

Most Canadians spend decades building retirement income.

Few spend any time thinking about how drawing that income will trigger a tax most of them didn't see coming.

The OAS clawback is one of the most avoidable costs in retirement.

It's also one of the most common.

Not because people haven't saved enough.

Because nobody coordinated the sequence.

What the OAS Clawback Actually Is

Old Age Security is a federal benefit paid to most Canadians starting at age 65.

In 2025, the maximum monthly OAS payment is approximately $727 for those aged 65 to 74.

But there is a threshold.

Once your net income exceeds $93,454, CRA begins clawing back your OAS at a rate of 15 cents for every dollar above that line.

At roughly $151,000 in net income, OAS is fully eliminated.

That is not a small number. But for HNW retirees drawing from RRIFs, non-registered accounts, investment income, rental properties, and corporate dividends simultaneously, it is closer than most expect.

The clawback is not the problem. Uncoordinated income is the problem.

Where It Breaks

Here is the scenario that plays out more often than it should.

A retiree has:

- A RRIF drawing down at a mandatory minimum rate

- Non-registered investments generating dividends and capital gains

- A rental property producing income

- CPP and OAS both in payment

On paper, each piece looks reasonable.

In practice, the income stacks.

The RRIF minimum is non-negotiable. CRA sets the rate, and it increases each year. By age 75, mandatory minimums are pulling significant income regardless of need.

Add CPP. Add rental income. Add non-registered investment income that was never structured for tax efficiency.

Now you are over $93,454.

Every dollar above that line costs 15 cents in clawback on top of marginal tax.

Two tax events on the same dollar. And it was often preventable.

The Sequencing Problem Nobody Talks About

OAS clawback is almost always a sequencing problem dressed up as an income problem.

The question is not how much retirement income you have.

The question is which accounts you draw from, in what order, and how that stacks against the threshold.

Most retirees draw income reactively. RRIF minimums run automatically. CPP starts because it feels like the right time. OAS turns on at 65 because that is what everyone does.

Nobody is actively managing the stack.

That is the gap.

The clawback is not what you pay at 75. It is what you did not plan at 62.

The Low-Income Window Strategy

The years between retirement and age 70 are often the most valuable planning window in a person's financial life.

Income is lower than it will be. CPP has not started, or can be delayed. OAS has not started, or can be deferred. A DB pension, if present, may have deferral flexibility. Mandatory RRIF minimums have not yet escalated.

That window is an opportunity.

Most retirees do not use it. They take CPP early, turn OAS on at 65, and let the RRIF run at minimums, because each decision feels reasonable in isolation.

Coordinated, those same decisions quietly build a clawback problem for the next two decades.

The strategy is to engineer that low-income window deliberately, and use it aggressively.

Step 1: Delay CPP and Pension Income

CPP can be deferred to age 70. Every month of deferral past 65 increases the benefit by 0.7%. The total increase from 65 to 70 is 42%.

OAS can also be deferred to age 70. Every month of deferral increases the benefit by 0.6%. Delay the full five years and OAS is 36% higher permanently.

Delaying CPP and OAS keeps net income lower in early retirement. That creates room to restructure RRIF assets at lower marginal rates before CPP, OAS, and pension income stack on top.

Note: CPP and OAS deferral does not make sense in every situation. Health, liquidity needs, and survivor considerations all matter. The point is that deferral creates planning room, and that room should be used intentionally, not ignored.

Step 2: Accelerate RRIF Draws Beyond the Minimum

This is the move most retirees never make, and the one that matters most.

While the low-income window is open, CPP delayed, OAS deferred, pension not yet in payment, draw RRIF assets faster than the mandatory minimum requires.

The goal is to pull taxable income forward at a lower marginal rate than it would face later.

Why This Works

At 65 with CPP and pension delayed, a retiree might be in the 33% marginal bracket.

At 72 with CPP running, OAS in payment, and mandatory RRIF minimums escalating, that same retiree could be in the 46-50% bracket, plus clawback on top.

Drawing RRIF income early means paying tax at 33% instead of 46-50%. The RRIF balance shrinks. Future mandatory minimums are smaller. The income stack at 72 is lower.

That is tax arbitrage. Pay less now to avoid significantly more later.

The Estate Dimension :This Is Critical

For many HNW retirees, an unmanaged RRIF does not just create a clawback problem during their lifetime.

It creates a massive tax bill at death.

Unless transferred to a surviving spouse or a financially dependent child, the entire RRIF balance is fully taxable as income in the year of death. Not capital gains. Not partially included. Fully taxable income.

At a large RRIF balance of $800,000, $1,200,000, $1,500,000, that terminal tax return hits the highest marginal rate. Depending on the province, the tax bill can approach 50% of the remaining balance.

CRA becomes one of the largest beneficiaries of the account.

The accelerated draw strategy solves two problems at once. It reduces clawback exposure during retirement. And it reduces the tax liability the estate faces at death.

That is the coordination argument. Two outcomes. One strategy.

Step 3: Convert Proceeds to TFSA

RRIF withdrawals generate tax. But the after-tax proceeds do not have to sit in a taxable non-registered account generating more income.

They go into the TFSA.

TFSA withdrawals are not included in net income. That means the money pulled forward from the RRIF, taxed once at a lower rate,now lives permanently outside the OAS clawback calculation.

It does not generate taxable income. It does not count toward the threshold. It can be drawn in retirement without triggering clawback.

The TFSA is not the strategy. It is where the strategy lands.

One practical note: this is a multi-year strategy. TFSA contribution room is based on annual limits plus unused room carried forward. Available room needs to be mapped before the draw strategy is built.

Pension Income Splitting

For couples, pension income splitting is one of the most direct tools for managing OAS clawback exposure.

Up to 50% of eligible pension income, including RRIF income after age 65, can be allocated to a lower-income spouse for tax purposes.

If one spouse has net income approaching the OAS threshold and the other is significantly below it, splitting can reduce the higher earner's net income and preserve OAS entitlement.

Most couples discover pension income splitting exists. Fewer use it as a deliberate planning tool built into a coordinated income strategy from the start.

The Business Owner Dimension

For those who built wealth inside a corporation, the clawback conversation has an additional layer.

Corporate dividends flow as personal income. Depending on dividend type, eligible or non-eligible, they count toward net income and can push a retiree over the OAS threshold quickly.

For business owners in the drawdown phase, the question becomes how to sequence corporate distributions against other income sources.

Years where RRIF minimums are lower may be the right years to take larger corporate draws. Years where RRIF minimums are higher may call for reduced corporate distributions and greater TFSA use instead.

This is plannable. But most business owners never had this conversation until OAS was already in payment and the clawback had already started.

What Good Planning Looks Like

OAS clawback planning is not a single decision. It is an income sequencing strategy built over time, reviewed annually, and adjusted as income sources and tax rules shift.

When the pieces are coordinated:

- CPP and OAS deferral extends the low-income window

- Accelerated RRIF draws reduce the balance and future mandatory minimums

- After-tax proceeds shift to TFSA and exit the clawback calculation permanently

- Pension income splitting manages the threshold for couples

- Corporate draw sequencing is timed against RRIF minimums

- The estate faces a smaller RRIF balance and a lower terminal tax bill

None of these decisions exist in isolation. Each one affects the others.

That is the coordination problem that turns a manageable tax situation into an expensive one.

The OAS clawback is not a tax problem. It is a sequencing problem. And sequencing problems are solved before they show up on your tax return.

Frequently Asked Questions:

What is the OAS clawback threshold in Canada?

In 2025, OAS begins to be clawed back once net income exceeds $93,454. The clawback rate is 15 cents per dollar above that threshold.

Can you delay OAS in Canada?

Yes. OAS can be deferred from age 65 up to age 70. Each month of deferral increases the benefit by 0.6%, for a maximum increase of 36% at age 70.

Do TFSA withdrawals affect OAS clawback?

No. TFSA withdrawals are not included in net income calculations and do not trigger OAS clawback.

What happens to a RRIF at death in Canada?

Unless transferred to a surviving spouse or a financially dependent child, the entire RRIF balance is taxed as income in the year of death, at the highest marginal rate.

Can pension income splitting reduce OAS clawback?

Yes. Allocating eligible pension income to a lower-income spouse reduces the higher earner's net income, which can reduce or eliminate clawback.

Does CPP income affect OAS clawback?

Yes. CPP payments count as net income and contribute to the clawback threshold calculation.

Can corporate dividends trigger OAS clawback?

Yes. Both eligible and non-eligible dividends count as personal net income and can push retirees over the OAS threshold.

When should I start planning for OAS clawback?

The most effective planning happens 5 to 10 years before OAS begins, when RRIF draw timing, TFSA room, and CPP deferral decisions still have room to move.

Final Thought

Retirement income looks simple from a distance.

CPP. OAS. RRIF. Maybe some investments.

But in practice, each source has timing implications, tax consequences, and threshold interactions that compound quietly, until they show up on a tax return that surprises everyone.

OAS clawback is one of the most visible examples of what happens when income sources are not coordinated.

The income was always there.

The plan to manage it was not.
