Why You Should (or Shouldn’t) Defer OAS To Age 70

Why You Should (or Shouldn’t) Defer OAS To Age 70

I’ve long advocated that anyone who expects to live a long life should consider deferring their Canada Pension Plan to age 70. Doing so can increase your CPP payments by nearly 50% – an income stream that is both inflation-protected and payable for life. If taking CPP at 70 is such a good idea, why not also defer OAS to age 70?

Many people are unaware of the option to defer taking OAS benefits up to age 70. This measure was introduced for those who retired on or after July 1, 2013 – so it is still relatively new. Similar to deferring CPP, the start date for your OAS pension can be deferred up to five years with the pension payable increased by 0.6% for each month that the pension is deferred.

OAS Eligibility

By the way, unlike CPP there is no complicated formula to determine your eligibility and payment amount. That’s because OAS benefits are paid for out of general tax revenues of the Government of Canada. You do not pay into it directly. In fact, you can receive OAS even if you’ve never worked or if you are still working.

Simply put, you may qualify for a full OAS pension if you resided in Canada for at least 40 years after turning 18 (when you turn 65).

To be eligible for any OAS benefits you must:

  • be 65 years old or older
  • be a Canadian citizen or a legal resident at the time your OAS pension application is approved, and
  • have resided in Canada for at least 10 years since the age of 18

You can apply for Old Age Security up to 11 months before you want your OAS pension to start.

Your deferred OAS pension will start on the date you indicate in writing on your Application for the Old Age Security Pension and the Guaranteed Income Supplement.

There is no financial advantage to defer your OAS pension after age 70. In fact, you risk losing benefits. If you’re over the age of 70 and not collecting OAS benefits make sure to apply for OAS right away.

Here are three reasons why you should defer OAS to age 70:

1). Enhanced Benefit – Defer OAS to 70 and get up to 36% more!

The standard age to take your OAS pension is 65. Unlike CPP, there is no option to take OAS early, such as at age 60. But you can defer it up to 60 months (five years) in exchange for an enhanced benefit.

Deferring OAS to age 70 can be a wise decision. You’ll receive 7.2% more each year that you delay taking OAS (up to a maximum of 36% more if you take OAS at age 70). Note that there is no incentive to delay taking OAS after age 70.

Here’s an example. The maximum monthly payment one can receive at age 65 (as of July 2021) is $626.49. Expressed in annual terms, that equals $7,553.88.

Let’s look at the impact of deferring OAS to age 70. Benefits will increase by 0.6% for each month of deferral, so by age 70 we’ll see a total increase of 36%. That brings our annual OAS pension to $10,273 – an increase of $2,719 per year for your lifetime (indexed to inflation).

2). Avoid / Reduce OAS Clawback

In my experience working with clients in my fee-only practice, retirees are loath to give up any of their OAS benefits due to OAS clawbacks. That means designing retirement income and withdrawal strategies specifically to avoid or reduce the OAS clawback.

The Canada Revenue Agency (CRA) calls this OAS clawback an OAS pension recovery tax. If your income exceeds $79,845 (2021) then you are required to pay back some or all of the OAS pension you receive from July 2022 to June 2023. For every dollar of income above the threshold, your OAS pension is reduced by 15 cents. OAS is fully clawed back when income exceeds $129,581 (2021).

So, does deferring OAS help avoid or reduce the OAS clawback? In many cases, yes.

One example I’ve come across many times is when a client works beyond their 65th birthday. In this case, they may want to postpone OAS simply because they’re still working and don’t need the income. In some cases, the additional income received from OAS would be partially or completely clawed back due to a high income. Deferring OAS to at least the next calendar year when you’re in a lower tax bracket makes a lot of sense.

Aaron Hector, financial consultant at Doherty & Bryant, says there is a clear advantage to postponing OAS if someone expects their retirement income to push them into the OAS clawback zone.

“Not only will postponement provide them with an enhanced OAS income, it will also in turn provide them with a higher clawback ceiling,” said Mr. Hector.

It might also allow the opportunity to draw down RRSP/RRIF assets between 65 and 70 which would reduce future expected retirement income (lower RRSP/RRIF assets = lower mandatory withdrawals between age 72 and death).

One could also stash any unspent RRSP/RRIF withdrawals into their TFSA. Growing their TFSA in retirement gives retirees the valuable ability to withdraw money tax-free any time and not have that income affect their means-tested benefits (such as OAS).

3). Take OAS at 70 to Protect Against Longevity Risk

It’s counterintuitive to defer taking pensions such as CPP and OAS (even with an enhanced benefit for waiting) because it forces retirees to tap into their personal savings – depleting their nest egg earlier and faster than they’d prefer. Indeed, people are reluctant to spend their capital.

But this is a good thing, according to Retirement Income For Life author Fred Vettese. Deferring CPP and OAS increases the amount of guaranteed income you will have for the rest of your life, while also reducing your long-term investment risk because you are spending your savings first.

“Spend your risky dollars first because they may not be there for you in your 80s, depending on how your investments do. A bigger CPP (or OAS) cheque, however, will definitely be there for you.”

In one example I looked at a single 59-year-old woman – Jill Smith – who plans to retire on July 1st when she turns 60. Jill requires $48,000 in after-tax spending each year to meet her retirement goals.

She has $775,000 saved in her RRSP, plus $75,000 in her TFSA and $30,000 in cash. She’ll qualify for 80% of the CPP maximum and is fully eligible for OAS.

If Jill takes CPP right away (July 2) at age 60 and takes OAS at the standard age 65 she’ll have enough personal savings to last until she’s 89. Her CPP and OAS pensions make up 30.39% of her total annual income in retirement.

CPP at 60, OAS at 65

Now let’s compare this scenario with deferring CPP and OAS to age 70.

Not only does Jill increase the viability of her retirement plan – her personal savings now last until age 92 – but she has increased the portion of index-protected, paid-for-life government pensions to 54.25% of her total annual income.

CPP and OAS at 70

Mr. Hector says that someone who fears running out of money in old age would be wise to postpone OAS to guarantee a higher base level of income when they are very old.

So those are three great reasons to take OAS at 70 – to enhance your annual OAS benefit, to reduce or avoid OAS clawbacks, and to protect against longevity risk.

Now let’s look at four reasons why you might not want to defer your OAS pension past 65.

1). The OAS Enhancement Is Less Enticing Than CPP

The actuarial adjustment you receive for deferring OAS to age 70 is much less than it is for deferred CPP to 70. It is just 36% compared to 42% for CPP. That makes a big difference, considering you’re foregoing your pension for five years. You want to make sure it’s worthwhile.

“When I compare the two side by side it really jumps out at you how there is a much greater incentive to deferring CPP than there is to defer OAS. This of course is due to the fact that there is a greater enhancement effect for CPP,” says Mr. Hector.

Ignoring income and clawback concerns, it is best to take OAS at age 65 for someone who is going to die between 65 and 79 for OAS, but for CPP the range shrinks to 65 to 77.

Taking OAS at age 70 gives the best outcome for those who live to age 88 and beyond.

2). Emotional Factor

Fred Vettese is a big proponent of deferring CPP until age 70 but not as enthusiastic about deferring OAS. He says that starting CPP late is already forcing the average retiree to draw down their RRIF balance much faster than they planned on doing. It is still a good move, but one that makes people uncomfortable.

He says asking people to start OAS late as well will accelerate the RRIF drawdown and make people that much more uncomfortable.

3). You Need The Money

Deferring CPP and/or OAS is a luxury for those who have the means to fund their lifestyle while they wait. Repeat: This is not a strategy for those who need to access their government benefits right away to get by.

Mr. Vettese says you need at least $200,000 saved before even considering the deferral strategy.

4). Leaving an Inheritance

Deferring OAS and CPP until age 70 means spending down a good portion of your personal savings in your 60s. This could also mean it’s possible to spend down most if not all of your personal savings before you die.

While this ‘die broke’ strategy may be ideal for some, others may wish to leave an inheritance to their loved ones or to charity.

As there is no survivor-OAS pension, someone who is concerned about leaving a large estate to their heirs may decide that they would rather take OAS earlier so that they can leave their investments intact.

“The investments will always have a value for their beneficiaries but that is not true for someone who opted to defer OAS,” says Mr. Hector.

Final Thoughts

There’s no clear-cut answer for deciding if and when to defer OAS.

When I’m working with clients, I always make sure they understand to at least postpone taking OAS until retirement, or the next calendar year after retirement to avoid OAS clawbacks and additional taxes in the final working year.

Then we look at OAS clawback amounts (if any) and see what can be done to avoid them. Sometimes that means taking more from their RRSP/RRIF in their 60s while deferring OAS until somewhere between ages 67 to 70.

But the bottom line is that deferring OAS to 70 is a bet that you’ll live a long life. And, like with an annuity, rather than worrying about what happens if we die early, we should give more thought to whether we’ll live longer than expected.

With that in mind, deferring OAS by 1-5 years can help transfer the risk from your personal savings to the inflation-protected, paid-for-life government pension program.

The more we can ‘pensionize’ our retirement income, the better off we’ll be if we happen to live an extraordinary long life.

    Hi Robb; ” If your income exceeds $77,580 (2019) ” — is that taxable income or gross income?

    Also, to avoid some potential clawback based upon too much mandatory RRIF withdrawals, there is the new 2020 ALDAnnuity option — which lets one buy up to 25% of one’s RRIF as an ALDA… thereby reducing the RRIF withdrawals by that 25% amount… which could keep one’s income below the clawback threshold.
    We still don’t know what these ALDAs will cost, and what perms and coms they may offer… and therefore if they’ll be of benefit in this fashion.

    • Robb Engen on February 18, 2020 at 6:07 pm

      Hi Toby, that amount is based on your net income.

      Good point about the advanced life deferred annuity. I haven’t dug much into this option but I’m hoping to either interview an expert or have a guest post on the topic.

      • Tony Whitaker on August 19, 2020 at 3:34 pm

        If you take OAS at 70, the maximum claw back cut-off income amount is slightly above $143,000.

      • Mary on August 27, 2021 at 12:49 pm

        To be clear: The clawback is based on your “net income before adjustments”, which is line 234 on your income tax return. There are certain deductions that do not apply to this net world income. Income splitting, if available in your specific situation, can be applied before line 234. I point this out as there is more than one interpretation of “net” and “gross” income.

  2. Steve Bridge on February 18, 2020 at 5:57 pm

    Excellent advice Robb! Sadly, very few other planners will give this kind of unbiased advice. Pretty much every commission-based advisor says to take CPP at 60 and not touch RRSPs until 72, which allows them to collect more commissions for a longer time period. I’m not sure if this is done with profit (theirs) in mind or not, but I do know that I agree with you completely when you say that delaying is in most people’s best interests.


    • Robb Engen on February 18, 2020 at 6:09 pm

      Thanks Steve! It’s such a personal decision that’s based on everyone’s unique circumstances, so I don’t want to make blanket rules of thumb that everyone must follow. Instead, I like to present the options, discuss the facts, and show clients (and readers) how these decisions can impact their retirement situation (for better or worse).

      • Steve Bridge on February 18, 2020 at 6:16 pm

        For sure – at the end of the day it’s a personal decision, but financially it is usually (but not always) best to delay. Sometimes I see my job kind of like a doctor- the patient may really enjoy smoking and not want to quit, but it’s my job to show you that quitting is best for you and your family. Many people feel like taking CPP at 60 is what they WANT to do, but I see our job is to show them what’s best for them. Like you, I am agnostic when it comes to the best solution – at the end of the day it’s the numbers that will tell the story.
        Ironically, as someone who intends on retiring early and will have a lot of CPP dropout years, I may end up taking my CPP at 60!

        • Marianne on August 30, 2021 at 2:18 pm

          Can someone explain how having many CPP dropout years will affect whether I delay or not? I am 61, still haven’t taken CPP or OAS, didn’t intend to until 70. However, I have not worked since 58. Would appreciate further detail on this point. Thank you very much.

          • Steve B on August 30, 2021 at 9:27 pm

            Marianne, I will defer to Robb but I would recommend hiring someone like Doug Runchey (contact him at DR Pensions) to run specific calculations for your personal circumstances.

      • Angelo Rao on March 14, 2021 at 8:37 pm

        I don’t understand the benefits of deferral. On is naively banking on a unknown mortality. Also ,when you defer you are leaving money on the table. For example 5 years worth of payments that if taken at 65 can be invested in the market toward property etc. When one waits to age 70, one is working backwards in that your higher benefits first have to go toward the monies lost for the 5 year deferral plus any investment income from that money. Only typically, according to a banker I know, approximately age 77 does either decision coincide, but at this point the benefits start to accrue in the postponement, but still at 77 the person receiving at 65 has a 12 year head start on the initial 5 year early payments received.
        The government, of course loves deferrals as statistically many people will die earlier than expected; disease, accidents, you name it, just ask God. Hence the payouts cease and one is out of luck. I took my CPP at 60 and am still benefiting by the investment benefits of monies I would otherwise never have had.
        I like to think of it this way: is it better to get a lesser lump sum of a lottery win or the full amount in installments? The answer, I believe is obvious, otherwise what is the stock market for?

    • Jay on December 17, 2020 at 8:14 am

      If you do the math, by deferring taking your OAS until 70 rather than 65, you miss out on around $35,000 for the five years. You will be 84 before you get this money back by getting the $200 more monthly after you turn 70. So, the question is….Do you feel lucky? If you live past 84 you will likely not care about the extra $200 a month and it will be worth a lot less after 19 years of inflation…..

      • Steve Bridge on December 17, 2020 at 4:17 pm

        Jay, the other consideration is the tax savings you gain by deferring OAS and CPP. You can take out more of your RRSP/RRIF money at a lower tax rate if no other (or at least less) taxable income. This also helps estate planning, as large amounts left in RRIFs are taxed at death as income. This can be quite considerable and makes probate look like chump change.

        • Jay on December 17, 2020 at 5:29 pm

          The OAS is $614.14 monthly. The average CPP payment is $710.41 monthly. This leaves lots of room to take out RRSP or RRIF money before hitting OAS clawback or a higher tax bracket.
          If somebody wants to give me $100.00, I will gladly give him back $20.00. I am still $80.00 ahead of having nothing…..Being able to split your income with a spouse is also a huge benefit. Putting off taking the OAS is like gambling, similar to an annuity or life insurance policy. You are placing a bet that you will live long enough to recoup the $35,000.00 lost.
          Statistics are not favourable.

          • David on August 25, 2021 at 5:00 pm

            Way long past published date, but article came up in my feed so…GIS is a solid reason to take OAS at 65 and postpone CPP. With proper allotment of withdrawals from TFSA’s, cash on hand and (judiciously) RRSPs, one could qualify for the GIS even though one has substantial financial resources. Not saying whether this is right or wrong, ethically, but getting up to $900 plus OAS plus draining in taxable TFSA as needed and non registered cash reserves sounds pretty good to me.

        • Jay on December 17, 2020 at 5:37 pm

          Life expectancy for male Canada 2017 is 82.25 yrs. For male U.S. 78.54yrs.

  3. Toby Stewart on February 18, 2020 at 6:26 pm

    HI Robb;
    This is the only site where I could find a firm offering to give a quote for an ALDA. I didn’t investigate yet, but you might want to check them out… based in Montréal which may have a Québec twist to it…?

    • Gord on January 28, 2021 at 11:09 pm

      The average life expectancy of a male Canadian is 82 years. However the life expectancy of a 65 year old Canadian male increases by 19.4 years (84.4).
      Further a 70 year old Canadian male, average life expectancy increases to 85.3 years. These are just averages, so many are likely to live considerably longer.
      Future investment returns are also expected to be much lower on account of the new low interest rate environment we’re in.
      Also, I’d suggest doing a google and YouTube search of Boomer Retirement Crisis to see some pretty scary stats on retirees finances. As well as the forecasts about the significant underfunding of public and private pensions.
      10,000 Baby Boomers are turning 65 years old, per day each and every day between now and 2030. In 2025, that increases to 12,000 Baby Boomers reaching 65 daily in the USA.

  4. Scott Harris on February 18, 2020 at 8:22 pm

    Hey Robb, how would the math shake out if you didn’t need OAS early but took it as soon as possible and invested it in something relatively conservative like VBAL. Say you obtained an average 5% return for those 10 years and lived to the average Canadian life expectancy of 82 years. How does this compare to the guy who delays until 70 and lives to the same age?

    • Denis on February 23, 2020 at 5:04 am


      I never thought of that, what if the ROI on early or normal (65) withdrawal earned 5% (actually a good adviser should be able to average 6%) versus leaving it in there until 70?

      Does that 1. mitigate those 36 and 42% increase in payments 2. reduce the risk of dying before at least breaking even?

      I was leaning towards taking both at 70 and taking out that current estimated amount from my RRSP until then (to simulate taking it all at 65).

      I await Robb’s answer and/or analysis with numbers.

      The main reason I wanted to take it out at 70 was to have the biggest cushion possible for later years when who knows what happens generally and what happens to my saving/RRSP etc and if I still have the cognitive to handle my investing in as productive way as I do now (in FIRE since 54).

    • Jay on December 17, 2020 at 5:47 pm

      Right on Scott. Take the OAS and invest it inside a TFSA and you pay no tax and it grows tax free as well.
      OAS and the average monthly CPP payment in Canada anounts to under $16,000.00 a year leaving lots of room to take out Retirement money – especially if you can income split.

  5. Gail Bebee on February 19, 2020 at 7:06 am

    What gets missed in the OAS discussion is that it is funded from general government revenues, and benefits could change at the whim of the government. One real possibility: the government could ratchet down the clawback income level. Another reason to take the OAS money and run as soon as it is offered.

  6. Allard Losier on February 22, 2020 at 4:31 pm

    Thanks for the excellent article. I’m curious as to your total rate of return and inflation assumptions you used for your conclusions regarding running out of savings at 89. Thank you.

  7. David B on July 17, 2020 at 2:05 pm

    Current strategy is to have employment income end in year I turn 70 (June) as current income places me well in the recovery tax zone and money isn’t needed. Can I wait to apply until following January so both CPP & OAS are be paid retroactive to my 70th birthday? In this way income in subsequent tax year is under $80,000 even with 1 1/2 years of enhanced OAS/CPP in my 71st year as other sources are tax free and/or preferred.

  8. Devon on November 15, 2020 at 3:58 pm

    If a new resident person qualifies for 10 years of residence by the age of 68. Would the personal also receive a 21.60% increase on the partial 10/40 OAS payment?

  9. Siv Sarkar on December 14, 2020 at 7:09 pm

    If somebody decides to defer OAS till 70 (because of increased benefit), he/she lose the GIS supplement too, right? But is this lose forever, or only for the period for his/her deferral of OAS ? And when he/she starts receiving OAS at 70, then he/she becomes eligible for the GIS supplement too? Please clarify. Thanks for response in advance.

    • James on August 27, 2021 at 1:04 pm

      You need to be collecting the OAS to be eligible for the GIS. Deferring your GIS payments for 5 years, or any time after age 65, would not be wise as you would be giving up so much more than your increased OAS would pay you. Delaying CPP may however prove beneficial as it would also enhance your GIS benefit.

  10. Rob Dales on January 28, 2021 at 5:35 am

    This was a great article , gives lots to think about. My question is I worked for the provincial government and when I reach 65 and receive OAS my provincial pension drops , if I defer the OAS how will that affect my provincial pension , will it still drop even though I am not collecting OAS?

  11. Kay Fisher on March 2, 2021 at 5:34 pm

    I deferred my OAS until July 2021, but then I sold my house and my OAS will be subject to clawback. So my question is, Can I defer my OAS again…this time to July 2022?

  12. RALPH BENTFELD on April 25, 2021 at 11:29 am

    I am wondering about the inflation consideration.
    Helicopter money from all Governments will probably ignite inflation.
    OAS and CPP are indexed to inflation. Your bond and stock portfolio’s are probably not. Low future returns coupled with inflation could be problematic for some. If your close to retirement you’ve been around long enough to know markets go down as well.
    Delaying until 70 would maximize indexed income if inflation is a concern…..and you can tap
    other income sources to get there.
    Just a consideration in the calculation.

    • Tina on June 30, 2021 at 11:04 am

      Totally agreeing with Ralph about inflation ahead…

      This is very much my concern now and knowing the OAS is indexed is comforting for me, as a very healthy 60 year old female. The challenge will be bridging until then, as my income isn’t high and I don’t have another pension.

      Great article and a helpful, refreshing perspective. Thanks

  13. Tony Whitaker on August 27, 2021 at 12:06 pm

    If you take OAS at 70 in 2021, maximum income before all clawback is used is more than $129,581. It is north of $140K.

    Rob, can you please provide the calculation as to what that number north of $129,581 is?

  14. Ariane on November 24, 2021 at 2:55 pm

    Is the husband’s income considered in the computation of the wife’s OAS if he is still working and the wife isn’t.
