In short

Most changes are indexation, every 20 March and 20 September, needing no action. Otherwise it was a decision — a review, a reported change, deeming, or overseas income — which you can have explained free and challenge within 13 weeks. Pensioners on the pre-2009 transitional rate face two changes that are permanent.

You have looked at your statement and the number is different. Nobody told you it would be, and no letter has arrived explaining it.

Almost every rate change falls into one of two categories, and working out which one you are looking at takes about a minute.

Either it was expected — indexation, or a change you reported working its way through — in which case there is nothing to do.

Or it was a decision — someone assessed something and your rate moved as a result. Decisions can be explained, and if you disagree with one, reviewed. But there is a clock on that, so it is worth knowing which category you are in.

Start with the likely and benign

Was it late March or late September? Then it was probably indexation. Services Australia states that "the Department of Social Services adjusts these rates every 20 March and 20 September" (https://www.servicesaustralia.gov.au/how-much-age-pension-you-can-get). This applies to everyone, arrives without an individual letter, and normally moves the rate up. It is by a wide margin the most common answer to this question, and our article on Age Pension rate indexation explains how it works.

Did you report something recently? A change in your financial situation, your living arrangements, your relationship, a sale, an inheritance? Reported changes flow through on Services Australia's timetable rather than yours, and often land a fortnight or two after you would expect.

Do you hold financial investments? Deeming decides the income Centrelink treats those as producing, regardless of what they actually earn — and deeming rates and deeming thresholds move on separate clocks from each other, and from pension indexation. A deeming change alone can shift your rate without anything in your own circumstances changing at all. See deeming rates and the Age Pension.

If one of those explains it, you can stop here.

The reassessment answers

An annual or periodic review. Services Australia periodically reassesses circumstances, and a review can move a rate without you having initiated anything — see the Age Pension annual review process.

Income or assets outside Australia. Services Australia notes directly that "if you or your partner get income from, or have assets outside Australia, this could affect your Age Pension."

A change someone else reported, or that was data-matched. Information reaches Services Australia from other agencies and from employers, and a rate can move on information you did not personally supply.

The one that does not reverse: the transitional rate

This one deserves its own section, because it affects a specific group who often do not know they are in it, and because what happens is permanent.

Where it came from. On 20 September 2009 the pension rules changed in several ways at once. The Department of Social Services records that the maximum basic rate went up, the additional income test free area for dependent children was removed, and — the change that did the damage for some people — "the income test withdrawal rate was increased from 40c to 50c for each extra dollar of private income above the income test 'free area'" (DSS Social Security Guide 5.1.8.40, Version 1.341, https://guides.dss.gov.au/social-security-guide/5/1/8/40). Pensioners with enough private income felt that steeper taper more than they gained from the higher base, so Parliament preserved the old position for them.

What it actually is. Not simply "the old income test", which is how it is usually described. The Guide is precise: the arrangements let a person "have their pension assessed under the pension rules that applied before 20 September 2009 plus an increase... or the rules that applied from that date, whichever provides a higher rate of payment." So it is old rules plus a fixed fortnightly increase, compared against the current rules, with the higher of the two paid. The legal basis is Schedule 1A clause 146 of the Social Security Act 1991, "Transitional provisions for rates of certain social security pensions on and after 20 September 2009" (DSS Social Security Guide 5.1.8.10, https://guides.dss.gov.au/social-security-guide/5/1/8/10).

Who is in it. Services Australia puts it simply: "The transitional rate started in 2009. It's for pensioners who would get a lower pension rate if we used the new income test." And: "If you were getting a pension on 19 September 2009, we may still be paying you at the transitional rate" (https://www.servicesaustralia.gov.au/transitional-rate-pension).

How you leave it. Services Australia says: "We regularly reassess what is the correct rate of pension for you." They compare the two results, and "if the current rate is the same or higher than the transitional rate, we'll pay you the current rate instead." Note when that happens: "This can happen if your income or assets change."

And then this:

"You can't go back to the transitional rate once you get the current rate of pension."

So an ordinary change — one you were obliged to report — can move you permanently onto the current rules. If your income or assets later move again in a way that would have suited the transitional rate better, that option no longer exists.

There is a second door, and it is sharper. The consumer page does not mention it, but the Guide does: "If the person ceases to receive a social security pension on or after 20 September 2009, the transitional arrangements cease to apply to the person. The person can no longer have their pension calculated under the transitional arrangements." Losing payability altogether — not merely being reassessed — ends the arrangements for good. Someone whose rate falls to nil, or whose payment stops for another reason, does not carry the transitional arrangements back in with them if they later re-qualify.

If you have been on the Age Pension since before September 2009 and your rate has changed in a way you did not expect, this is worth asking about specifically. Services Australia's own page suggests a service officer or a Financial Information Service officer can explain how your rate is worked out, and the FIS service is free and independent of any product.

When a rate change is really a warning

There is one version of this that is not about your rate at all.

If your payment has been reduced because Services Australia has become aware of something you did not report, the rate change may be the visible edge of a larger problem — because the period during which you were paid at the higher rate may now be assessed as an overpayment. Our article on the 14-day rule for notifying changes covers the obligation, and if a debt notice follows, what to do about a Centrelink debt you think is wrong sets out the pathway — including the fact that you can ask for repayments to be paused while you dispute it.

How to find out which one it actually was

Stop guessing and ask. You can request an explanation of a decision at any time. It costs nothing, an independent and experienced staff member calls you, and Services Australia states that "if we find an error in the decision, we'll fix it." They aim to make contact within 14 days.

That single call resolves the question. Either you learn it was indexation or a reported change — reassuring, and the matter ends — or you learn what was assessed and on what basis, which is what you need before deciding whether to challenge it.

Worked strategy examples

Both are illustrative only and neither turns on a dollar amount.

Margaret, 73, single full pensioner, noticed her payment move in early April. She had not reported anything, received no letter, and assumed something had gone wrong. Two things had happened at once. Her rate had been adjusted at the 20 March indexation, which applies to everyone and arrives without an individual letter. Separately, the deeming settings applying to her term deposits had moved, which changes the income Centrelink treats those deposits as producing regardless of what the bank actually pays her — and deeming rates and deeming thresholds run on clocks of their own. On these facts there is nothing to do and nothing to challenge: no decision was made about Margaret, two scheduled adjustments simply landed in the same statement. If she wanted certainty rather than inference, the free explanation would confirm it within about a fortnight, which is generally the rational step for anyone who cannot tell indexation from a decision by looking.

Frank, 81, on the Age Pension continuously since 2007, sold a small parcel of shares. He reported the sale, as he is legally required to do. At the next reassessment Services Australia compared his transitional entitlement against the current rules, found the current rate now produced the same or more, and moved him onto it. His payment did not fall — but the transitional arrangements are now gone, and Services Australia states plainly that "you can't go back to the transitional rate once you get the current rate of pension." If his circumstances shift again in a direction the old rules would have handled more kindly, that comparison is no longer run for him. Nothing here was avoidable: the sale happened, reporting it was an obligation, and the reassessment is Services Australia's to make, not Frank's to time. What is worth doing on these facts is understanding it — a Financial Information Service officer can explain which basis he is now paid on and what that means going forward, which is more useful than discovering it years later.

If you disagree with the change

A rate change is a decision, and decisions are reviewable. That means the same machinery as a rejected claim, and the same deadline: you should apply for a formal review within 13 weeks of being told about the decision. You can apply later and still succeed, but if the decision is then changed you may only be paid from the date you applied rather than from when the change took effect.

The mechanics are identical to those set out in what to do when an Age Pension claim is rejected — a free formal review by an Authorised Review Officer, then the Administrative Review Tribunal if you disagree with that. If the underlying question is how your income has been assessed, the Age Pension income test is the place to check whether the assessment matches your actual position.

The point

Most Age Pension changes are indexation, and if yours landed in late March or late September you can almost certainly stop worrying.

Where it was not indexation, it was a decision — and decisions come with an explanation you are entitled to for free, and a 13-week window if you want to challenge them.

The one to watch is the transitional rate. If you have been on the pension since before 20 September 2009, a routine change in your income or assets can move you onto the current rules permanently — and losing the payment altogether ends the arrangements just as finally. Both doors are one-way, and both are stated in terms by the agencies that administer them. That is worth understanding before you reach one, rather than discovering it afterwards.

Key takeaways

  • Sort it into two boxes first. Either the change was expected — indexation on 20 March or 20 September, or something you reported flowing through — or it was a decision, and decisions can be explained and reviewed.
  • Deeming can move your rate with nothing changing in your own circumstances, because deeming rates and deeming thresholds run on separate clocks from each other and from pension indexation.
  • THE TRANSITIONAL RATE IS THE ONE THAT DOESN'T REVERSE. If you were getting a pension on 19 September 2009 you may still be on it. It is not simply 'the old income test' — the pension is worked out under the pre-2009 rules plus a fixed fortnightly increase, or the current rules, whichever pays more. Services Australia regularly reassesses which applies.
  • TWO separate doors close permanently. Services Australia: 'You can't go back to the transitional rate once you get the current rate of pension' — triggered by a reassessment your income or assets changing. And the DSS Social Security Guide adds a second the consumer page omits: if you cease to receive a pension at all on or after 20 September 2009, the transitional arrangements cease to apply and cannot be recalculated under later.
  • An explanation is free and available at any time, with a 14-day contact aim, and Services Australia says that if an error is found it will be fixed. If you disagree with the decision, apply for a formal review within 13 weeks or you may lose backdating.

Frequently asked questions

My Age Pension changed in March — is that normal?

Almost certainly yes. Services Australia states that the Department of Social Services adjusts pension rates every 20 March and 20 September. Indexation applies to everyone, arrives without an individual letter, and normally moves the rate up. If your change landed in late March or late September and no letter arrived, indexation is by far the most likely explanation and there is nothing you need to do.

My rate changed but nothing changed in my circumstances. How?

Several things can move your rate without you doing anything. Deeming is the most common — it decides the income Centrelink treats your financial investments as producing regardless of actual earnings, and deeming rates and thresholds move on separate clocks from each other and from pension indexation. A periodic review or data matching can also trigger a reassessment, as can income or assets held outside Australia. Ask for an explanation to find out which.

What is the transitional rate of pension?

When the pension income test changed on 20 September 2009 — the withdrawal rate rose from 40c to 50c for each dollar of private income above the free area — pensioners who would have been worse off were protected. Services Australia says that if you were getting a pension on 19 September 2009, they may still be paying you at the transitional rate. It is not simply the old income test preserved: the DSS Social Security Guide describes the pension being assessed under the pre-2009 rules plus a fixed fortnightly increase, or the rules that applied from that date, whichever gives the higher rate. The statutory basis is Schedule 1A clause 146 of the Social Security Act 1991.

Can I go back to the transitional rate if my circumstances change again?

No, and there are two separate ways to lose it permanently. Services Australia states directly: 'You can't go back to the transitional rate once you get the current rate of pension' — which happens when a reassessment finds the current rules pay you the same or more, and they note that can happen if your income or assets change. The DSS Social Security Guide adds a second the consumer page does not mention: if you cease to receive a social security pension at all on or after 20 September 2009, the transitional arrangements cease to apply and your pension can no longer be calculated under them. So a payment that stops — not merely a reassessment — also closes the door. If you have been on the pension since before September 2009, a free Financial Information Service officer can explain your position.

What if I think the change is wrong?

Ask for an explanation first — it is free, available at any time, an experienced staff member calls you, and Services Australia says that if an error is found it will be fixed. If you understand the decision and still disagree, apply for a formal review by an Authorised Review Officer. You should do that within 13 weeks of being told about the decision; you can apply later and still succeed, but you may only be paid from the date you applied rather than from when the change took effect.
