The Benefit Everyone Gets and Few People Understand
Old Age Security is the retirement benefit Canadians are most sure they understand and least likely to have read about. Most people know it starts at 65 and that it is “small.” Fewer know that it is earned by residence rather than contributions, that you can be paid more for waiting, that high earners hand part of it back through the tax return, that it can stop 6 months after you leave the country, or that it has no survivor benefit at all.
My thesis is simple. OAS looks like the easiest piece of the Canadian retirement system, but the three decisions that move real money (whether to delay it, how to keep the clawback from eating it, and whether it follows you abroad) each depend on rules most people have never read. A fourth question has now joined them: whether the income thresholds that trigger the clawback will come down. That is a live policy debate, and anyone with a six-figure retirement income should have a view on how exposed they are.
A word on method. Amounts are those published for October to December 2026. The federal budget is scheduled for November 5, 2026, and if it changes anything in this article I will update it. Where I calculated something myself, I say so. Where a number comes from an advocacy group, I say that too.
What OAS Actually Is and Who Qualifies
OAS is a monthly pension paid out of general federal revenue. You do not contribute to it through payroll deductions, which is the key difference from the Canada Pension Plan. It is earned by living in Canada, and it does not matter whether you worked.
The rules, in plain terms:
You must be 65 or older and a Canadian citizen or legal resident when the pension is approved. You need at least 10 years of residence in Canada after turning 18 to qualify while living in Canada, and at least 20 years to keep receiving it while living outside Canada. The amount is built on 40 years: 40 years of residence after age 18 earns the full pension, and each complete year short of that earns 1/40 of it.
A worked example makes the point. Someone with 32 years of residence gets 32/40, or 80%, which is CAD 610.00 a month at 65 on today’s maximum. Someone who immigrated at 45 has 20 years by 65 and gets 20/40, or CAD 381.25 a month. They qualify, but they do not get a full pension, and no later planning move fixes that.
Working has no effect on eligibility, and you do not have to be retired. Years spent in a country that has a social security agreement with Canada can count toward the 10-year minimum, and some years abroad working for a Canadian employer can count as residence. Both depend on your own history, so confirm your residence count with Service Canada before you build a plan on it.
Most people are enrolled automatically and receive a letter around their 64th birthday. If you do not get one, apply roughly 6 months before you turn 65. If you miss the date, ESDC can pay up to 11 months retroactively, but not for any months you chose to defer.
What OAS Pays in Late 2026
| Age | Maximum monthly (Q4 2026) | Maximum annual |
|---|---|---|
| 65 to 74 | CAD 762.50 | CAD 9,150 |
| 75 and older | CAD 838.75 | CAD 10,065 |
Source: ESDC payment amounts for October to December 2026. Annual figures are my multiplication of the quarterly amount and ignore indexation during the year.
Amounts are indexed to inflation every quarter and cannot go down. Since July 2022 the pension rises by 10% starting the month after your 75th birthday, automatically, with no application. OAS is fully taxable income.
Should You Delay OAS Past 65?
The deal on the table
You can postpone your first payment by up to 60 months. Each month of delay raises your pension by 0.6%, which is 7.2% a year, and the maximum is 36% at age 70. The increase is permanent, indexed, and the age-75 bump applies on top of the larger amount.
| Start age | Monthly amount (Q4 2026) | Increase over age 65 |
|---|---|---|
| 65 | CAD 762.50 | 0.0% |
| 66 | CAD 817.40 | 7.2% |
| 67 | CAD 872.30 | 14.4% |
| 68 | CAD 927.20 | 21.6% |
| 69 | CAD 982.10 | 28.8% |
| 70 | CAD 1,037.00 | 36.0% |
Source: ESDC deferral table for the current quarter; I checked each row against the 0.6% a month rule.
What you pay for that is 60 months of forgone payments: 60 times CAD 762.50, or CAD 45,750 before tax. What you buy is CAD 274.50 more every month for the rest of your life, indexed to inflation. CPP offers a richer version of the same trade (0.7% a month, 42% at 70), which is why the two are usually discussed together.
You cannot get GIS or the Allowance while you are deferring, and you can cancel a deferral within 6 months of your first payment if you change your mind.
The breakeven math
I ran the numbers monthly, including the age-75 bump on both paths. The question is how long you have to live before the larger pension has paid back the payments you skipped.
| Real discount rate | Start at 66 | Start at 67 | Start at 70 |
|---|---|---|---|
| 0% (undiscounted) | 79.5 | 80.4 | 83.1 |
| 2% | 81.8 | 82.8 | 86.0 |
| 4% | 85.4 | 86.8 | 91.2 |
My calculation. Each cell is the age at which cumulative payments from starting later catch up with starting at 65. Before tax and before any clawback.
A cleaner way to see the same thing is the real return you earn, after inflation, on the payments you give up.
| If you die at | Real return on deferring 65 to 70 |
|---|---|
| 75 | minus 11.4% |
| 80 | minus 3.6% |
| 85 | 1.4% |
| 90 | 3.7% |
| 95 | 4.9% |
| 100 | 5.5% |
My calculation, before tax and clawback.
Statistics Canada’s preliminary 2024 life expectancy at birth was 82.16 years overall, 80.03 for men and 84.29 for women. A 65-year-old has already got past the early deaths that pull those averages down, so the average age at death for someone reaching 65 is higher. That is why this decision is closer than the headline suggests.
My read: delaying to 70 is longevity insurance, not a bargain. You are buying a government-backed, inflation-indexed annuity at a price that pays off if you reach your mid-80s and pays well if you reach your 90s. It is a poor trade if your health or family history points the other way. Notice also that the first year of delay is the best-priced one: deferring only to 66 earns about 3.9% real if you live to 85, against 1.4% for the full five years. If you want the benefit of waiting without the full cost, a year or two captures the cheapest part.
When the clawback changes the answer
Everything above treats OAS as untouched by the recovery tax. For higher earners that is wrong, and it flips the conclusion.
The recovery tax depends on your income, not on the size of your pension (until it reaches the full OAS you received). That has a surprising consequence. If you start at 65 with a high income, a large share of every payment is clawed back, so the real cost of delaying is small. If you defer, you reach 70 with a pension 36% larger, and that extra amount is not clawed back until your income is much higher.
I modelled this using 2026 Ontario combined tax rates, a flat real income, the 2026 clawback threshold, and the age-75 bump. Income below is before OAS.
| Income before OAS | Deferring to 70, real after-tax return if you die at 80 | at 85 | at 90 |
|---|---|---|---|
| CAD 60,000 | minus 3.6% | 1.4% | 3.7% |
| CAD 100,000 | minus 2.8% | 2.1% | 4.2% |
| CAD 120,000 | 5.0% | 8.7% | 10.1% |
| CAD 130,000 | 12.0% | 14.8% | 15.7% |
| CAD 140,000 | 28.0% | 29.3% | 29.6% |
| CAD 150,000 | No cost: OAS started at 65 is fully repaid | n/a | n/a |
My calculation. It ignores personal credits, assumes income stays flat in today’s dollars and thresholds stay where they are, and applies Ontario’s 2026 combined marginal rates to the OAS itself. Treat it as a direction, not a forecast. A CAD 140,000 earner who starts at 65 keeps about CAD 600 a year after tax and clawback; the same person at 70 keeps about CAD 2,200.
The pattern is the point. Below the clawback zone the return is the plain longevity-annuity return. Inside the zone, deferral is far more attractive than the headline numbers suggest, because you are giving up very little. At around CAD 150,000 of other income, starting at 65 pays you nothing after clawback, and deferral costs nothing at all. Past roughly CAD 165,000 you get nothing either way.
The caution: my model holds income flat. Real retirement incomes move. RRIF minimums rise with age, CPP starts, a house sells. Run your own year-by-year version before relying on this. The answer also depends on the thresholds staying where they are.
Who should not delay
Do not defer if you could qualify for GIS, because deferring means you do not get it. Do not defer if you have under 20 years of residence and plan to live abroad, because a larger pension that stops 6 months after you leave is worth nothing. Do not defer if your health points to a short horizon or you need the cash. And do not treat a deferral as free money if you are on a partial pension: the 36% applies to a smaller number (a 32/40 pension goes from CAD 610.00 to CAD 829.60 a month at 70), and deferral does not repair a thin residence record.
The OAS Clawback
How the recovery tax works
The official name is the OAS recovery tax, and the clawback is what everyone calls it. It is 15% of your net income above a threshold, capped at the OAS you received in the year. Net income for this purpose starts from line 23400 of your return, with a few adjustments, and it is your income alone.
Collection works on a lag. ESDC withholds from your payments from July to June based on the prior year’s income. You reconcile on your tax return: the repayment is deducted at line 23500, and the amount withheld appears in box 22 of your T4A(OAS). Because the repayment is deductible, you pay income tax on net income after it.
| Income year | Clawback starts | OAS fully repaid, ages 65 to 74 | OAS fully repaid, age 75 and older |
|---|---|---|---|
| 2025 (drives July 2026 to June 2027) | CAD 93,454 | CAD 152,062 | CAD 157,923 |
| 2026 (drives July 2027 to June 2028) | CAD 95,323 | CAD 155,320 | CAD 161,320 |
Source: ESDC recovery tax thresholds. Several aggregator sites still show older or incorrect figures; use these.
What this looks like in dollars, using the 2026 threshold and the Q4 2026 annual pension of CAD 9,150:
| Net income | Recovery tax | Share of OAS lost |
|---|---|---|
| CAD 95,323 | CAD 0 | 0% |
| CAD 100,000 | CAD 702 | 8% |
| CAD 110,000 | CAD 2,202 | 24% |
| CAD 120,000 | CAD 3,702 | 40% |
| CAD 130,000 | CAD 5,202 | 57% |
| CAD 140,000 | CAD 6,702 | 73% |
| CAD 150,000 | CAD 8,202 | 90% |
| CAD 155,320 | CAD 9,000 | 98% |
| CAD 170,000 | CAD 9,150 | 100% |
My calculation: 15% of income above CAD 95,323, capped at CAD 9,150.
One-time income matters here. A year with an unusual spike, such as the sale of a cottage or rental, a large capital gain, or collapsing an RRSP, can push you into the zone for that year even if every other year is modest. The following year’s withholding reflects the spike, and then it falls away.
What it does to your marginal rate
Inside the zone you pay income tax and the recovery tax on the same dollar, so the real marginal rate is higher than your bracket. Because the repayment is deductible, the arithmetic is 15% plus 85% of your marginal tax rate.
| Net income range | Ontario combined marginal rate | Effective rate inside the clawback zone |
|---|---|---|
| CAD 95,323 to CAD 107,785 | 31.48% | 41.76% |
| CAD 107,785 to CAD 111,785 | 33.89% | 43.81% |
| CAD 111,785 to CAD 117,045 | 37.91% | 47.22% |
| CAD 117,045 to CAD 150,000 | 43.41% | 51.90% |
| CAD 150,000 to about CAD 155,320 | 44.97% | 53.22% |
My calculation applied to Richter’s 2026 Ontario combined rates. The table uses taxable income breakpoints as a proxy for net income and ignores credits and surtax interactions beyond the published rates. The zone ends where OAS is fully repaid.
This is the planning problem in one table. Earning an extra dollar of RRIF income at CAD 130,000 costs about 52 cents, not 43. It is also why the levers matter: income splitting, drawing on a TFSA rather than an RRSP or RRIF (TFSA withdrawals do not count as income), and managing when an RRSP becomes a RRIF. My comparison of RRSP and TFSAexplains the trade-offs.
Single Versus Married: The Clawback Is Individual
There is no couple clawback. Each spouse is tested on their own income. The household does not matter to the recovery tax, which is why the same combined income can produce very different outcomes.
| Couple | Spouse A income | Spouse B income | A’s recovery tax | B’s recovery tax |
|---|---|---|---|---|
| Lopsided | CAD 150,000 | CAD 40,000 | CAD 8,202 | CAD 0 |
| Balanced | CAD 100,000 | CAD 90,000 | CAD 702 | CAD 0 |
My calculation using the 2026 threshold and CAD 9,150 annual OAS.
Both couples have the same combined income of CAD 190,000. The first loses CAD 8,202 and the second loses CAD 702. The only difference is how the income is distributed.
That is where pension splitting comes in. OAS itself cannot be split between spouses. Eligible pension income can: at 65 and older that includes RRIF payments, defined benefit pension income and annuity payments. Moving 30,000 of that from the higher earner in the lopsided couple cuts their net income by CAD 30,000 and their recovery tax by 15% of that, or CAD 4,500 a year, while the spouse stays well below the threshold at CAD 70,000. That is a large result from a form filed with the return (T1032). Confirm the rules for your own pension types with CRA or an adviser.
Marriage does matter in one place: GIS and the Allowance are tested on combined income, not individual. That is a different system, and it is worth keeping the two apart.
A Brief Word on GIS
The Guaranteed Income Supplement is an income-tested top-up for lower-income OAS recipients living in Canada. For Q4 2026, ESDC lists a maximum of CAD 1,138.90 a month for a single senior with income (other than OAS) below CAD 23,112. Couples are tested on combined income, with different cutoffs depending on whether the spouse receives OAS or the Allowance.
I do not expect many readers here to qualify. If you have a parent who might, I have a post on moving money for a low-income parent and GIS. A full GIS reference is a separate topic. For this article, GIS matters in three places: you cannot collect it while deferring OAS, it is the reason a low-income senior should not delay, and it is recalculated when a spouse dies.
What Happens If You Leave Canada
OAS is a residence benefit, so leaving matters in two ways: whether it keeps paying, and what tax comes off when it does.
Whether it keeps paying. If you have at least 20 years of residence in Canada after 18, OAS can follow you abroad indefinitely. If you have less, payment stops once you have been outside Canada for more than 6 months (the month you leave plus six). GIS and the Allowance stop after 6 months abroad regardless of years of residence. This is a hard stop, not a tax question, and it is the single most expensive thing a short-residence retiree can get wrong.
What tax comes off. Canada withholds non-resident tax on OAS paid abroad. The default rate is 25%, and treaty rates can lower it by country. ESDC publishes the table. From the version I read, the rate varies a lot depending on where you retire:
| Country | OAS withholding rate |
|---|---|
| United States, United Kingdom | 0% |
| Mexico, Portugal, Spain, Colombia, Ecuador, Malaysia | 15% |
| Dominican Republic | 18% |
| Finland | 20% |
| Italy, Netherlands, Croatia, Philippines | 25% |
| Thailand, Costa Rica, Panama, Belize, Japan, France, Vietnam, Indonesia | 25% |
Source: ESDC non-resident tax rate table as I read it in October 2026. Rates and conditions change, treaties distinguish between types of payment, and several countries have additional rules. Verify your own country before relying on this.
Do not assume the 25% default applies everywhere, and do not assume a treaty rate applies automatically either. Some treaties include exemptions on the first slice of income. For example, my reading of the Portugal entry is that a first slice of CAD 12,000 can be exempt with the right paperwork. Check treaty by treaty.
As I read ESDC’s chart, non-residents also have their own recovery tax calculation, which applies a 75% factor to the resident version, and the combined non-resident tax and recovery tax cannot exceed the OAS paid. Non-residents file an OAS Return of Income (T1136) by April 30, though CRA publishes a list of countries for which no filing is required. For the wider picture of what leaving does to your tax position, see my pieces on departure tax and snowbirds versus full relocation, and the country guides for Portugal, Thailand and Costa Rica.
A practical point for expats: CPP is contribution-based and portable, while OAS is residence-based and treaty-taxed. They are different bets, and someone retiring in a 25% country is paying a real price for the OAS half.
Survivors: There Is No OAS Survivor Pension
The answer is short: OAS has no survivor benefit. If your spouse dies, you do not inherit their OAS, and your own OAS does not rise.
What exists instead:
The pension for the month of death is payable. Payments after that month stop, and anything deposited after death has to be returned, so tell ESDC promptly.
The Allowance for the Survivor is for widowed people aged 60 to 64 who live in Canada and have not remarried or entered a common-law relationship. For Q4 2026 the maximum is CAD 1,726.18 a month, and your income must be below CAD 31,152. It ends at 65, when OAS and possibly GIS take over, and ends earlier if you re-partner.
GIS is recalculated for a surviving spouse on their own income, at the single rate. If you are the survivor, report the death promptly so the recalculation starts.
The money that actually changes in a household when one spouse dies is mostly CPP, not OAS. My CPP guide covers the survivor benefit and the death benefit. For a couple the lesson is practical: a household loses one OAS cheque, and a survivor whose income now sits in a higher range can cross into clawback territory on a single income, because pension income no longer splits.
Will the Clawback Thresholds Come Down?
Anyone with retirement income in the CAD 90,000 to CAD 170,000 range has probably heard this argument: OAS was never meant for retirees who are doing this well. It is worth separating what is true today from what is being proposed.
What the rule already is
OAS already has an income test. It starts at CAD 95,323 for the 2026 income year and removes the pension entirely at about CAD 155,320 to CAD 161,320. Between those figures it is a partial means test. The debate is not whether high earners should lose OAS; many already do. It is whether the line should move down, and whether it should be measured on household income instead of individual income.
The case for lowering the thresholds
The most visible proposal comes from Generation Squeeze, a think tank led by UBC’s Paul Kershaw. It asks retirees with household income over CAD 100,000 to take less from OAS, and it describes the effect as roughly 1 in 5 retirees seeing a reduction of about CAD 3,000 after tax. As reported by Global News, the plan would lower the point where benefits begin to phase out for couples from about CAD 185,000 to CAD 100,000. The group’s estimated savings are CAD 7 billion a year, rising to about CAD 9 billion by 2030. A lower threshold of CAD 81,000 would save about CAD 13 billion a year. The group also says OAS will pay about CAD 17.5 billion a year by 2030 to households above CAD 100,000.
Its arguments are the ones you would expect, and some are strong:
The group says OAS is the largest federal program and takes nearly one-fifth of the federal budget. The Auditor General’s December 2024 report on programs to assist seniors found that the department could not show whether the basic OAS payment is enough to support seniors’ financial security. An across-the-board increase, the group argues, is a poorly targeted way to help people who need it, and it points to about 400,000 seniors below the poverty line. It compares the CAD 100,000 level with the Canada Child Benefit cutoff of about CAD 81,000 and median family income of about CAD 74,200, and argues that seniors can hold far more income than families before benefits are reduced. Its plan would send part of the savings to low-income seniors (about CAD 5,000 a year for the poorest) and the rest to housing, child care and other programs for younger people. A March 2026 poll the group commissioned from Research Co. (about 1,000 Canadians, March 12 to 14) found 73% in favour of trimming OAS for higher-income seniors, with support tied to the savings going to senior poverty and to younger generations.
There is also a point the debate tends to skip. The existing rule treats identical households differently. Two spouses each earning CAD 94,000 lose nothing, while a household with one spouse earning CAD 188,000 and the other nothing loses that spouse’s whole pension, and the other spouse keeps theirs. Anyone who accepts the premise that OAS should shrink with household means has to accept that the current individual test does not measure it well.
The case against
CARP, the retirees’ advocacy group, has pushed back hard. Its president, Anthony Quinn, has argued in print that the proposal would roughly double the scale of the cut by moving from individual to household income, and that a couple averaging CAD 50,000 each could see steep clawbacks or lose OAS entirely. CARP says fewer than 4% of seniors earn over CAD 100,000, only a fraction earn over CAD 150,000, and that the savings would therefore come largely from middle-income retirees who paid taxes all their lives and rely on OAS. It points to the cost of retirement living (about CAD 60,000 a year for a basic retirement home with meals, about double that with care). It supports closing loopholes that let wealthy retirees with large liquid assets manage their declared income, and it opposes funding younger-generation programs by taking from seniors.
What the numbers do and do not say
Three observations.
First, the disagreement over who is affected is mostly an argument about the unit of measurement. CARP’s “fewer than 4%” counts individuals over CAD 100,000. Generation Squeeze’s “1 in 5 retirees” counts households over CAD 100,000. Both can be true at once, and they describe very different policies.
Second, I could not find the proposed clawback rate in the sources I read. That matters. To show scale only, apply today’s 15% to a CAD 100,000 household threshold: a couple at CAD 184,000, which loses nothing today, would owe 15% of CAD 84,000, or CAD 12,600, out of roughly CAD 18,300 of combined OAS. A couple at CAD 150,000 would owe CAD 7,500. That is my arithmetic, not their proposal. It also means I could not reproduce CARP’s claim about couples at CAD 50,000 each: at CAD 100,000 household and a 15% rate, that couple loses nothing. Either the rate, the threshold or the design differs from what I found.
Third, there is no federal commitment. In the coverage I read, the government has not said it will adopt a lower threshold, and the Bloc Quebecois has pushed in the opposite direction, for a broad increase. The federal deficit for the current year is estimated at about CAD 65.3 billion, and the budget arrives on November 5, 2026. I am treating a change as possible, not announced.
How I would plan around it
I would plan as though OAS might be smaller, not as though it will be. If your retirement income sits in the CAD 90,000 to CAD 170,000 band, your plan should still work if your OAS is a bonus rather than a core line item. That points toward four habits: build income flexibility (a bigger TFSA and balanced registered accounts across spouses make your income controllable), keep eligible pension income splittable, avoid decisions that only work if the current thresholds persist, and treat a long deferral with caution if it depends on staying inside the current zone. Note that the delay analysis above is most favourable to deferral exactly where this policy risk is highest.
What I’d Actually Do
- Count your years first. Before I plan anything else about OAS, I confirm my residence history with Service Canada: the 10-year minimum, the 20-year rule if I might live abroad, and the 40-year test for a full pension.
- Defer a little, not automatically. If I am healthy, do not qualify for GIS, and do not need the cash, I would consider deferring a year or two, which is the best-priced part of the trade. I would only go to 70 if I was comfortable with a break-even in the mid-80s or later.
- Run the clawback before I decide. If my income before OAS will sit between about CAD 100,000 and CAD 150,000, I would model deferral seriously, because on my flat-income numbers the cost of waiting is small there and the payoff is large.
- Fix the income mix before 65. I would use pension splitting for RRIF and defined benefit income, balance incomes between spouses where I can, and draw from a TFSA when I want cash without increasing net income.
- Watch one-time income. I would plan the sale of a cottage or rental, or a large RRSP withdrawal, around the clawback year, not just the tax year.
- Check the treaty before I move. If I might retire abroad, I would verify the OAS withholding rate for my country, confirm I have 20 years of residence, and confirm what happens to any GIS.
- Plan the survivor gap, not an OAS benefit. I would assume there is no OAS survivor pension, check CPP survivor and death benefits, and model the surviving spouse’s income on a single return.
OAS is not complicated because the benefit is large. It is complicated because it sits at the intersection of residence rules, tax mechanics and politics, and each of those can change your outcome by thousands of dollars a year. The people who do well with it are not the ones who get the biggest cheque. They are the ones who know the rules before they need them.
