MSBS Pension in Retirement: The Complete Guide for ADF Members

If you served in the Australian Defence Force between 1991 and 2016, your Military Superannuation and Benefits Scheme (MSBS) pension is likely your most valuable retirement asset. This guide covers everything you need to know about how your MSBS pension works in retirement — calculation, tax, indexation, Age Pension interactions, and how to model it alongside your other assets.

1. What is MSBS?

The Military Superannuation and Benefits Scheme (MSBS) — commonly called MilitarySuper — is a defined benefit superannuation scheme for Australian Defence Force members who joined between 1 October 1991 and 30 June 2016. It replaced the older DFRDB scheme and was itself closed to new ADF entrants from 1 July 2016, when new members began joining the accumulation-only ADF Super fund.

MSBS is administered by the Commonwealth Superannuation Corporation (CSC), the same body that administers the PSS and CSS schemes for Australian Public Service employees. Like PSS and CSS, MSBS pays a guaranteed income for life — indexed to CPI — rather than a balance that can run out.

Unlike PSS and CSS, MSBS has a dual structure: a defined benefit pension component and a separate accumulation component called the productivity benefit. Understanding both is essential for retirement planning.

2. How your pension is calculated

Your MSBS pension is calculated using the formula:

Annual pension = Final Average Salary (FAS) × Benefit Multiple (BM)

Final Average Salary is typically your average superannuation salary over the final three years of service (or a shorter period if applicable).

The Benefit Multiple accrues over your career based on your member contribution rate and years of service. MSBS members could elect to contribute at 5%, 10%, or 15% of salary. Higher contribution rates generate a faster-accruing benefit multiple — reflecting the choice between a larger pension and more take-home pay during service.

As a rough illustration: a member who contributed at 5% for 20 years might accumulate a benefit multiple in the range of 0.40–0.55, producing a pension of 40–55% of final salary. Contributing at higher rates for the same period can produce a substantially larger multiple. However, the precise accrual formula is complex and depends on your specific contribution history.

Use the CSC i-Estimator for your individual figure. The i-Estimator is CSC's online tool that draws on your actual contribution history to produce a personalised pension estimate at your chosen retirement age. It is accessible through your CSC member account at csc.gov.au. Any general calculator — including this guide — cannot replicate the precision of a personalised estimate from CSC.

3. The productivity benefit

In addition to the defined benefit pension, MSBS members accumulate a productivity benefit — an employer-funded accumulation component separate from your defined benefit entitlement. Productivity contributions (broadly equivalent to the Superannuation Guarantee in the private sector) were paid into a CSC-managed investment account throughout your service.

Unlike the defined benefit pension, the productivity benefit balance fluctuates with investment returns and is not guaranteed. At retirement you generally have a choice of:

For retirement planning purposes, the productivity benefit is best treated as a separate pool of accumulation super — distinct from your lifetime pension income. It is the component most analogous to a standard super balance, and it is what you'll typically roll over and draw on in addition to your pension income.

Important: The options available for your productivity benefit depend on your specific circumstances and elections. Contact CSC directly before making any decision about how to take your productivity benefit at retirement.

4. Immediate vs preserved pension

Whether your MSBS pension commences immediately on separation from the ADF — or is preserved until a later age — depends on your age and years of service at the time you leave.

Members who reach the qualifying conditions may be entitled to an immediate pensionthat commences on separation. The rules are complex and depend on your category of service, age, and effective service — they are not simply a matter of reaching a minimum age or years served. Members who separate before meeting those thresholds will typically have their benefit preserved.

A preserved MSBS pension does not commence until you reach your preservation age — between 55 and 60 depending on your date of birth (60 for members born after 30 June 1964) — and satisfy a condition of release. During the preservation period, your preserved pension amount is generally CPI-indexed from the date of separation, so it is not eroded in real terms while you wait — but it also doesn't grow in line with wages or market returns.

For members who separated in their 40s or early 50s — common in the ADF — the gap between separation and pension commencement can be 10–20 years. Modelling that gap, and the income you'll need to bridge it, is one of the most important planning exercises for MSBS members.

5. CPI indexation

MSBS pensions are indexed by the Consumer Price Index (CPI) twice each year — on the first pension payday in January and July. The January increase uses the September quarter CPI movement; the July increase uses the March quarter CPI movement. This is the same indexation mechanism as PSS and CSS pensions.

For July 2026, the projected increase is approximately 2.0% — see our detailed pension indexation 2026 article for the full calculation and historical rates.

One important long-term consideration: CPI indexation preserves the real purchasing power of your pension, but it has historically tended to grow more slowly than wages over long periods. The Age Pension, by contrast, is indexed to the higher of CPI or Male Total Average Weekly Earnings (MTAWE), meaning it tends to outpace a CPI-only pension over long retirements. Over a 20–30 year retirement, the MSBS pension's real value remains stable, but its value relative to living standards may gradually decline.

Note also that the indexation has a floor: if CPI falls in any period, your pension stays the same — it is never reduced due to deflation.

Indexation dateBased onIncrease
July 2026March quarter 2026 CPI~2.0% (projected)
January 2026September quarter 2025 CPI0.8%
July 2025March quarter 2025 CPI1.0%
January 2025September quarter 2024 CPI1.3%

6. Tax treatment

MSBS pension tax treatment is more complex than a simple "taxed" or "untaxed" classification because the pension consists of two components that are taxed differently.

The two pension components

Because the employer component is typically the larger portion of the pension, most members will pay some tax on their pension even after age 60 — at marginal rates less the 10% offset. This is a meaningful difference from the common assumption that MSBS pensions are tax-free post-60.

AgeTaxed component (productivity)Untaxed component (employer benefit)
Under preservation ageMarginal rateMarginal rate
Preservation age to 59Marginal rate less 15% offsetMarginal rate (no offset)
60 and overTax-free (up to DBIC)Marginal rate less 10% offset (up to DBIC)

Source: CSC factsheet MS08. Concessional treatment is capped at the Defined Benefit Income Cap ($125,000 for 2025-26) — see Section 7.

Invalidity pensions may qualify for additional tax concessions if the benefit meets the definition of a disability superannuation benefit under the ITAA 1997 — requiring certification by two medical practitioners that the member is unlikely to ever work in a capacity for which they are reasonably qualified. A 15% offset on the taxed component applies in this case regardless of age.

Note: CSC withholds tax based on ATO guidelines but does not have access to your full tax position — additional tax may be payable at year-end. Tax treatment varies depending on your age, component proportions, invalidity status, and pre-1983 service. Seek advice from a tax professional familiar with defined benefit schemes.

7. Defined Benefit Income Cap (DBIC)

Introduced from 1 July 2017, the Defined Benefit Income Cap limits the tax-free treatment of defined benefit pensions. The cap is set at one-sixteenth of the general Transfer Balance Cap.

Financial yearDBIC
2025-26 (current)$125,000
2024-25$118,750
2023-24$118,750
2022-23$106,250

Because MSBS has both taxed and untaxed components, the DBIC affects each differently. For the taxed component above the cap, 50% of the excess is included in assessable income and taxed at marginal rates. For the untaxed componentabove the cap, the 10% offset ceases to apply — the full amount is taxed at marginal rates. See our PSS and CSS guide for how the cap applies to purely untaxed schemes like CSS.

Most MSBS members will not be affected — a $125,000 threshold is above the pension level of the majority of members. However, it is worth checking if you have a long career with high contribution rates, or if you also receive other defined benefit income that counts toward the cap.

8. Transfer Balance Cap (TBC) interaction

When your MSBS pension commences, it counts against your personal Transfer Balance Cap (currently $2 million for new retirees from 1 July 2025). The "special value" of your pension for TBC purposes is:

Special value = Annual pension × 16

A $65,000 per year MSBS pension therefore has a special value of $1,040,000 — consuming 52% of the $2 million TBC. This can significantly limit how much of your productivity benefit (or other accumulation super) you can convert into an account-based pension.

For members with larger pensions — typically long-serving officers or those who contributed at higher rates — the defined benefit special value can consume most or all of the TBC, meaning the productivity benefit must either remain in accumulation phase or be drawn on separately. This affects your minimum drawdown strategy and tax planning.

Unlike account-based pensions, the special value of a defined benefit pension does not decrease over time as pension payments are made — it is a one-time credit when the pension commences.

9. Age Pension interactions

Your MSBS pension counts as income under the Age Pension income test. However, a "deductible amount" — based on the return of your own contributions to the scheme — reduces the assessable income figure. Services Australia calculates this individually based on your personal contribution history.

Many lifetime defined benefit pensions receive concessional assets-test treatment, meaning the income test is often the more significant constraint. However, this treatment is not universal — it applies most clearly to pre-2015 grandfathered income streams. MSBS members commencing their pension today do not have grandfathered status, and Centrelink's treatment can vary depending on individual circumstances and the specific nature of the income stream. Confirm your assets-test position with Services Australia before assuming the income test is the only constraint that applies to you.

The interaction is particularly important for members who take an immediate pension in their 50s and receive the MSBS pension for many years before Age Pension age. By the time they reach 67, the combined effect of the income test and any other income sources needs careful modelling.

Note also that the productivity benefit, once rolled over to an account-based super fund, will be assessed under both the assets test (as a financial asset) and the income test (under deeming rules) — unlike the pension component.

10. Reversionary pensions

Most MSBS pensions include a reversionary pension — a continuation of a portion of your pension paid to your spouse or eligible dependant after your death. The reversionary fraction is 67% of your pension for death as a pensioner, though invalidity, commutation choices, and other circumstances can affect the outcome.

The reversionary pension is CPI-indexed and continues for the spouse's lifetime. Your spouse should be aware of two planning implications:

Note: Reversionary pension rules are scheme-specific and depend on individual elections made at retirement. Confirm your reversionary arrangements with CSC directly.

Frequently asked questions

What is the CSC i-Estimator and how do I use it for MSBS?+

The i-Estimator is an online tool provided by the Commonwealth Superannuation Corporation (CSC) that allows MSBS members to estimate their pension and lump sum benefits at different retirement ages. It draws on your actual member data held by CSC and produces personalised projections. You access it through your account at csc.gov.au. Because it uses your real contribution history, it is far more accurate than any general calculator for determining your individual benefit multiple and pension amount.

How does the MSBS productivity benefit work?+

The MSBS productivity benefit is an accumulation component funded by employer productivity contributions — separate from your defined benefit pension. At retirement, you can take the productivity benefit as a lump sum, roll it over to another super fund, or in some cases use it to supplement your pension. Unlike the defined benefit component, the productivity benefit balance is invested in CSC funds and fluctuates with investment returns. It is important to factor both components into your retirement planning.

Is the MSBS pension affected by the Transfer Balance Cap?+

Yes. When your MSBS pension commences, its "special value" counts against your Transfer Balance Cap (TBC). The special value is calculated as your annual pension amount multiplied by 16. For example, a $65,000 per year MSBS pension has a special value of $1,040,000, consuming 52% of the $2 million TBC for new retirees from 1 July 2025. This limits the cap space available for any additional account-based pension from your productivity benefit or other super.

How does an MSBS pension affect the Age Pension?+

Your MSBS pension counts as income under the Age Pension income test, but a deductible amount — based on the return of your own contributions — reduces the assessable figure. Services Australia calculates your deductible amount individually when you apply. Under the assets test, a defined benefit pension is generally not assessed as an asset. RetireConfident supports the deductible amount directly: enter it under the Income test deductible amount field, which appears below the pension income entry. If unknown, leave it at $0 for a conservative estimate.

What happens to my MSBS pension when I die?+

Most MSBS pensions include a reversionary pension paid to your spouse or eligible dependant after your death. The reversionary fraction is 67% of your pension for death as a pensioner. The reversionary pension is CPI-indexed and continues for the spouse's lifetime. Your spouse should be aware that when the reversionary pension commences, it counts against their own Transfer Balance Cap — potentially limiting how much of their own super they can hold in pension phase.

What is a preserved MSBS pension?+

If you leave the ADF before reaching the qualifying age or service threshold for an immediate pension, your MSBS benefit is preserved. A preserved pension does not commence until you reach your preservation age — between 55 and 60 depending on your date of birth (60 for members born after 30 June 1964) — and satisfy a condition of release. In the meantime, your preserved pension amount is generally CPI-indexed from the date of separation. It is important to understand when your preserved pension will commence and how it will be calculated, as this can significantly affect your retirement income planning.
