Fixed-term annuities: guaranteed income for a set period — and where they fit in retirement

A fixed-term annuity (also called a term-certain annuity or simply a term annuity) is an income product bought from a life insurer that pays a guaranteed regular income for a set number of years rather than for life. You hand over a lump sum — from your super or other savings — and in return receive a guaranteed amount of income for a fixed period, after which the payments stop. It is the lesser-known sibling of the lifetime annuity: where a lifetime annuity pays for the rest of the annuitant's life and insures against the risk of living a long time, a fixed-term annuity pays for a defined period and then ends. Fixed-term annuities aren't an "income for life" solution; they are a tool for a defined need — bridging the years between early retirement and Age Pension age, covering a period until another income source begins, locking in guaranteed income for the first risky years of retirement, or matching a known future liability. Their Centrelink and tax treatment differs from lifetime annuities, and they sit as one building block in a layered retirement income plan rather than the whole answer. For retirees who want certainty over a known horizon — without market risk, but also without paying for longevity protection they may not need for that period — the fixed-term annuity is worth understanding.

What does the product itself look like?

The product is straightforward. A single purchase price buys a guaranteed regular income — monthly, quarterly, or annually — for a fixed number of years, and the amount is set at the time you buy based on how much you paid, how long the money is invested for, and how often you take payments. At the end of the term the income simply ceases; there is no lifetime component. Two features matter most. First, the residual capital value (RCV) chosen at purchase: at one extreme the capital is fully consumed over the term (an RCV of zero), which maximises the income paid along the way, and at the other the full purchase price is returned as a lump sum at the end, with only the interest paid out as income — lower income, but the capital comes back. Second, whether payments are level or rise each year by a fixed percentage or in line with inflation; indexed payments start lower and grow over the term, which helps protect against the rising cost of living. Because the features and conditions vary between products, it is worth comparing before buying.

How does it differ from a lifetime annuity?

The most important thing to be clear about is the distinction from a lifetime annuity. A fixed-term annuity pays for a set period; a lifetime annuity pays for life. Crucially, a fixed-term annuity provides no longevity protection — if the annuitant outlives the term, the income stops and they must fund the rest of their life from other sources. A lifetime annuity insures against exactly that risk. So the two serve different purposes: the fixed-term annuity is for a defined-period need where the end date is known and acceptable; the lifetime annuity (or the Age Pension) is for the lifelong income-security need. Using a fixed-term annuity where the real need is income for life would be a mistake — it leaves the longevity risk uncovered. Matching the tool to the nature of the need, term versus life, is the first decision.

What are fixed-term annuities actually good for?

The common uses are where fixed-term annuities earn their place. The classic one is bridging to Age Pension age — funding the gap between early retirement (or preservation age, now 60 for anyone born on or after 1 July 1964) and the age the Age Pension starts at 67, with guaranteed income over that defined period. A related use is bridging to another income source — covering the time until a deferred lifetime annuity begins, an inheritance is expected, or downsizing proceeds arrive. Another is providing income certainty for a horizon — locking in guaranteed income for, say, the first five to ten years of retirement, which has the valuable effect of reducing sequencing risk (the danger of poor investment returns early in retirement) by taking that early income off the market. Fixed-term annuities can also match a known future liability over a period, or be laddered — combining different terms, or layered with lifetime annuities and account-based pensions — as part of a structured income strategy. In each case the defining feature is a defined period with a known end.

How is a fixed-term annuity treated for Centrelink purposes?

The Centrelink treatment differs from a lifetime annuity and is worth getting right, because it affects the Age Pension impact of the purchase. Under the income test, Services Australia assesses the gross payment less a "deduction amount," which represents the return of your own capital — so part of each payment is treated as returned capital and not counted, and only the balance is assessed. Under the assets test, a longer-term annuity (a term of more than five years) is assessed at its purchase price, reduced every six or twelve months on a straight-line basis over the term down to any residual capital value. A short-term annuity — one with a term of five years or less — is treated differently again: Services Australia counts it as a financial asset and applies deeming, currently 1.25% on the first $66,800 of financial assets for a single person ($110,600 for a couple, following the 1 July 2026 threshold indexation) and 3.25% above that. Importantly, the favourable assets-test concession that assesses only 60% of the purchase price (dropping to 30% later) applies only to qualifying lifetime income streams purchased on or after 1 July 2019 — it does not apply to fixed-term annuities, which are assessed under the standard income-stream rules above. A retiree should not expect the lifetime-annuity concession from a fixed-term product.

How is a fixed-term annuity taxed?

The tax treatment follows the source of the money. If the fixed-term annuity is bought with super money and the annuitant is 60 or over, the payments are generally tax-free, the same treatment that applies to a super pension from age 60. If it is bought with non-super money, the deduction-amount rules apply for tax too: each payment is split into a tax-free return of capital and a taxable earnings component, with the split depending on the purchase price, the term, and the RCV. So a super-sourced fixed-term annuity for a retiree over 60 is typically tax-free, while a non-super one carries a partly taxable income stream — a genuine consideration in deciding which money to use.

What are the returns, advantages and limitations?

The income reflects a guaranteed rate set at purchase, based on prevailing interest rates and the term and RCV chosen — broadly comparable to a term deposit structured as an income stream, but with the income-stream Centrelink and tax treatment and the RCV options. Choosing an RCV of zero gives higher income (the capital is consumed) than an RCV of 100% (the capital is returned and only interest is paid out), and rates are more attractive when interest rates are higher. The advantages are guaranteed income with no market risk for the term, certainty over a defined period, usefulness for bridging, reduced sequencing risk early in retirement, and the deduction-amount Centrelink treatment. The limitations are significant and must be weighed: no longevity protection (income stops at term end); generally limited liquidity (early access is restricted or penalised); inflation risk if the payments aren't indexed; and opportunity cost, since the rate is locked in and you miss any market upside. What happens on death during the term depends on the product — payments usually stop unless a reversionary beneficiary was nominated or a guaranteed period was chosen at purchase, in which case a beneficiary receives the remaining payments, often at a reduced level such as 60% of the income.

Where does it fit in a layered income plan?

Fixed-term annuities are best used as one layer of a structured plan. A common framing layers retirement income into three: a bridging layer (a fixed-term annuity covering a defined early period, such as the years to Age Pension age, with guaranteed income); a longevity layer (a lifetime annuity and/or the Age Pension covering the lifelong income-security need); and a growth and flexibility layer (an account-based pension providing flexibility and market exposure for the rest). In this framing the fixed-term annuity is one building block — typically the bridging or early-certainty layer — not the whole solution. The alternatives for defined-period income deserve comparison too: a term-deposit ladder (similar security, more liquidity, but deemed rather than getting the deduction-amount treatment), an account-based pension drawdown (flexible but not guaranteed), or a bond ladder. The choice depends on the need for a guarantee, the desired Centrelink treatment, liquidity needs, and the interest-rate environment.

Worked examples

These two cases show fixed-term annuities in use. They are illustrative only and not personal advice.

Susan, 61, retires early after reaching her preservation age, but the Age Pension is still six years away at 67. She has $900,000 in super and wants guaranteed, certain income for those six bridging years while keeping the rest invested for the long term. On these facts a fixed-term annuity suits the bridging need well. Susan could use part of her super to buy a six-year fixed-term annuity; because it is super-sourced and she is over 60, the income is generally tax-free, and it provides guaranteed income through to Age Pension age, taking those six years of income off the market and protecting against a poor sequence of early returns while the balance of her super stays invested for growth. She would likely choose a low RCV to maximise income over the bridge, since the Age Pension and her remaining super take over afterward. On these facts it is generally rational to size the annuity to her income need for the bridge, choose the term and RCV deliberately, and keep the rest of her super invested — the fixed-term annuity doing exactly what it is good at, guaranteed income for a known, defined period.

Reg, 68, is attracted to "an annuity" for guaranteed income and is considering a ten-year fixed-term annuity — but what he really wants is security for the rest of his life. On these facts the fixed-term annuity is the wrong tool for his stated need. A ten-year fixed-term annuity would stop paying at age 78, yet Reg may well live into his late eighties or nineties, leaving the back end of his life uncovered because a term product gives no longevity protection. His real need is lifelong income security. On these facts it is generally rational to look first to the tools built for a lifelong need — the Age Pension as his guaranteed lifelong floor and, if he wants more guaranteed lifelong income, a lifetime annuity, which insures longevity and may attract the favourable assets-test concession that assesses only 60% of the purchase price for qualifying lifetime products bought from 1 July 2019. A fixed-term annuity might still have a role for a specific defined-period sub-need, but not as his core lifelong solution. The case illustrates the key discipline: match the term tool to a term need and the lifelong tool to a lifelong need.

For retirees who need guaranteed income over a defined period, the fixed-term annuity is a useful, lower-profile tool. The work is to identify the defined-period need — bridging to Age Pension age, bridging to another income source, early-retirement sequencing protection, or matching a known liability — confirm it is genuinely a term need and not a lifelong one (because fixed-term annuities give no longevity protection), choose the term and RCV to match the need, model the Centrelink treatment (the deduction amount and assets-test rules, noting the lifetime-annuity concession does not apply), model the tax treatment (super-sourced and 60-plus generally tax-free; non-super via the deduction amount), compare with the alternatives, and fit it into the broader layered plan alongside lifelong income and flexible growth assets. The fixed-term annuity isn't glamorous and isn't a whole retirement income solution on its own — but for the specific job of providing guaranteed, certain income over a known horizon, most classically bridging the years to Age Pension age, it is a clean and effective building block. The discipline is simply to use it for a term need, not a lifelong one, and to weigh its certainty against its illiquidity and the longevity risk it leaves uncovered beyond the term.
