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.
- MSBS (MilitarySuper) — ADF members who joined 1 October 1991 to 30 June 2016.
- DFRDB — older Defence scheme for members who joined before 1 October 1991. Different indexation rules apply — see our indexation article.
- ADF Super — accumulation-only scheme for members who joined from 1 July 2016. No defined benefit pension component.
2. How your pension is calculated
Your MSBS pension is calculated using the formula:
Annual pension = Employer Benefit ÷ Pension Conversion Factor
Final Average Salary (FAS) is your average superannuation salary over the final three years (1,095 days) of service.
The Employer Benefit Multiple accrues purely with length of service — it is not affected by your contribution rate. It grows at 0.18 per year for your first seven years, 0.23 per year for years 8–20, and 0.28 per year beyond 20 years. Thirty years of service gives a multiple of 7.05 (7 × 0.18 + 13 × 0.23 + 10 × 0.28). FAS × multiple is your Employer Benefit as a lump sum.
The Pension Conversion Factor (PCF) converts that lump sum into a lifetime CPI-indexed pension. It is 12 at age 55, reducing slightly for every day you are older when you claim — 11 at 60, 10 at 65, and it never falls below 10. A lower divisor means a larger pension, so claiming later increases the annual amount twice over: the multiple keeps growing while you serve, and the conversion factor keeps shrinking until 65.
Worked example: FAS of $100,000 after 30 years of service gives an Employer Benefit of $100,000 × 7.05 = $705,000. Claimed as a pension at age 55, that is $705,000 ÷ 12 = $58,750 per year, CPI-indexed for life.
What about your contribution rate? Member contributions (5% minimum, 10% maximum, paid from after-tax salary — there is no salary-sacrifice option for them) build your separate Member Benefit, an accumulation account. They do not change the employer multiple above. The main strategic consideration in contributing above 5% is that a faster-growing benefit can reach your Maximum Benefit Limit (MBL) sooner — MSBS has a lump sum MBL and a pension MBL, and CSC contacts you with options when you reach one. Salary-sacrificed amounts go to a third component, the Ancillary Benefit, not the Member Benefit.
Maximum Benefit Limits (MBL) — mainly a long-career issue
MSBS caps the total benefit you can accrue. You reach a Maximum Benefit Limit when your Member Benefit plus Employer Benefit equals the limit, which is set as a fixed amount or a multiple of your Final Average Salary and revised annually. There are two: the lump sum MBL and the higher pension MBL. Most members never reach either — it is a consideration for those doing a full 30+ year career.
At the lump sum MBL you may elect to cease member contributions (or continue until you reach the pension MBL, deciding at any time). At the pension MBL you must stop — CSC notifies Defence. Either way, once member contributions cease, Defence's 3% productivity contributions also cease and your Employer Benefit Multiple stops accruing.
The two cessations differ in how permanent they are. If you elect to stop at the lump sum MBL, you cannot resume contributing — not in this period of service and not in any future one. If you stop compulsorily at the pension MBL, you cannot resume during that period of service, but a new pension MBL applies to each period: re-join MilitarySuper later and you can contribute again. That asymmetry is worth understanding before electing to cease early.
Your employer benefit keeps growing after contributions cease, but by a different route: while you continue serving, a formula tracks increases in your FAS and in the MBLs themselves (set out in Appendix A of CSC's MS31 factsheet); once you leave the ADF, the benefit is fixed at transition by that formula and then grows with fund earnings and CPI. Ancillary contributions — including salary sacrifice — can continue throughout. One tax consequence to note: members past the pension MBL are still treated as accruing for tax purposes, so CSC keeps reporting a notional Defined Benefit Contribution to the ATO each year, and it still counts towards your concessional contributions cap.
| Final Average Salary | Lump sum MBL | Pension MBL |
|---|---|---|
| Less than $98,040 | $781,810 | $977,160 |
| $98,040 to $156,520 | 8 × FAS | 10 × FAS |
| $156,521 to $290,340 | $313,040 + 6 × FAS | $469,560 + 7 × FAS |
| Greater than $290,340 | $1,184,060 + 3 × FAS | $1,340,580 + 4 × FAS |
Worked example (CSC's own): a member with a FAS of $105,000 has a lump sum MBL of $840,000 (8 × $105,000) and a pension MBL of $1,050,000 (10 × $105,000). At 25 years of service the employer benefit alone grows by $29,400 a year (0.28 × FAS), so the gap closes faster than most members expect once they are past 20 years.
Members approaching an MBL generally weigh three paths: remain in MSBS to retirement; leave MSBS and open an ADF Super account for the 16.4% employer contribution on Ordinary Time Earnings (the MSBS benefit stays preserved, but MSBS death and invalidity cover is traded for ADF Cover); or discharge. The insurance difference matters as much as the contribution rate, and the decision cannot be undone — a clear case for personal financial advice and a conversation with CSC. See CSC's MilitarySuper Maximum Benefit Limits (MS31) factsheet for the detail.
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
Your MSBS entitlement has three components. The Employer Benefit is the defined benefit covered above — it includes the productivity benefit, an employer-funded accumulation slice (about 3% of super salary, broadly analogous to the Superannuation Guarantee) paid into a CSC-managed investment account throughout your service, with the balance of the Employer Benefit paid from consolidated revenue. The Member Benefit is your own 5–10% after-tax contributions plus fund earnings — it behaves like a standard accumulation fund and follows normal superannuation preservation rules. An Ancillary Benefit holds anything else: salary sacrifice, rollovers, spouse and government contributions.
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:
- Taking the productivity benefit as a lump sum (rolled over to another super fund or taken as cash, subject to tax)
- In limited circumstances, some members may be able to use part of the productivity benefit to adjust their pension arrangements — though commutation and conversion options are constrained and not universally available
- Leaving it invested within CSC if eligible
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 Employer Benefit can generally be claimed as a lifetime pension from age 55 — even if you are still working in a civilian job. The exact options at claim time (pension, lump sum where permitted, or a combination) depend on your exit type and circumstances — confirm your own options with CSC before planning around them. This is a scheme rule that pre-dates the general rise in superannuation preservation age: the standard preservation age (60 for anyone born after 30 June 1964) applies to your Member Benefit, the accumulation component, but not to the defined benefit pension. During the preservation period your Employer Benefit is 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 30s or 40s — common in the ADF — the gap between separation and age 55 can still be a decade or more. 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 confirmed increase is 2.0% (CSC processed the adjustment in June 2026) — 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 date | Based on | Increase |
|---|---|---|
| July 2026 | March quarter 2026 CPI | 2.0% (confirmed) |
| January 2026 | September quarter 2025 CPI | 0.8% |
| July 2025 | March quarter 2025 CPI | 1.0% |
| January 2025 | September quarter 2024 CPI | 1.3% |
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
- Taxable taxed component — productivity contributions and interest converted to pension. These were taxed on entry to the fund (a taxed source). This component becomes tax-free once you turn 60, subject to the Defined Benefit Income Cap.
- Taxable untaxed component — the employer-funded defined benefit component. This is from an untaxed source. It does not become tax-free at 60. Once you turn 60, a 10% tax offset applies on this component (up to the DBIC), meaning it is taxed at your marginal rate less 10%.
- Tax-free component — only applies if you have pre-July 1983 service and transferred from DFRDB to MilitarySuper.
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.
| Age | Taxed component (productivity) | Untaxed component (employer benefit) |
|---|---|---|
| Under preservation age | Marginal rate | Marginal rate |
| Preservation age to 59 | Marginal rate less 15% offset | Marginal rate (no offset) |
| 60 and over | Tax-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 ($131,250 for 2026-27) — 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 year | DBIC |
|---|---|
| 2026-27 (current) | $131,250 |
| 2025-26 | $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 $131,250 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:
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:
- When the reversionary pension commences, it counts against their own Transfer Balance Cap — potentially limiting how much of their own superannuation they can hold in pension phase.
- The reduction to 67% of your pension represents a meaningful drop in household income. Modelling the survivor scenario — with one income stream instead of two — is an important part of retirement planning for MSBS couples.
Note: Reversionary pension rules are scheme-specific and depend on individual elections made at retirement. Confirm your reversionary arrangements with CSC directly.
11. Modelling your MSBS pension in RetireConfident
RetireConfident's Retirement Readiness Calculator and Retirement Manager both support MSBS pensions. The recommended approach is to model the two MSBS components separately:
- MSBS pension — enter your after-tax annual pensionunder the Defined benefit pension (after tax) field in the Income Streams section, set to your pension commencement age. Using this field (rather than Other income) also unlocks the Income test deductible amount sub-field. The calculator does not calculate income tax, so you need to determine your after-tax figure yourself. Because the untaxed employer component is taxed at marginal rates less a 10% offset (not tax-free), there is no simple rule — use Section 6 above and consider seeking tax advice to calculate the correct net figure for your situation.
- Productivity benefit — enter as your main superannuation balance at retirement age, alongside any other accumulated super.
- Survivor scenario — use couple tracking mode and configure the reversionary pension (67% for death as a pensioner) as a partner income stream. The calculator will model the income reduction when one partner dies.
- Age Pension — the calculator applies the income test automatically against your modelled pension income. It now supports the income test deductible amount: enter your deductible amount (Services Australia calculates this from your personal contribution history) in the sub-field beneath the pension income entry. If you don't know it yet, leave it at $0 — the result will be a conservative estimate. You can confirm your actual deductible amount with Services Australia when you apply for the Age Pension.
- Pre-commencement gap — if your pension is preserved and doesn't start until 60, use the Pre-Retirement Accumulation calculator to model the period between separation and pension commencement.

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.
What is the MSBS Maximum Benefit Limit (MBL) and will it affect me?+
MSBS limits the total benefit you can accrue. You reach a Maximum Benefit Limit when your Member Benefit plus Employer Benefit equals a limit set as a fixed amount or a multiple of your Final Average Salary, revised annually. There are two: the lump sum MBL, where you may elect to cease member contributions, and the higher pension MBL, where you must stop. Once member contributions cease, Defence’s 3% productivity contributions also stop, your Employer Benefit Multiple stops accruing, and a separate formula applies under the MSBS Rules. Electing to cease at the lump sum MBL is permanent — you cannot resume in this or any future period of service — while compulsory cessation at the pension MBL applies to that period of service only, and a new pension MBL applies if you re-join later. Most members never reach an MBL; it mainly affects those serving a full 30+ year career. Options include remaining in MSBS, leaving MSBS for an ADF Super account with its 16.4% employer contribution (which means giving up MSBS death and invalidity cover), or discharging. Seek personal financial advice before deciding.
How does the MSBS productivity benefit work?+
The MSBS productivity benefit is an accumulation component funded by employer productivity contributions of about 3% of super salary. Formally it forms part of your Employer Benefit — the funded slice, with the balance paid from consolidated revenue. 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 qualifying for an immediate pension, your MSBS Employer Benefit is preserved — and CPI-indexed while you wait. You can generally claim it as a lifetime pension from age 55, even if you are still working in a civilian job — though the exact options at claim time depend on your exit type; confirm with CSC. Standard superannuation preservation age (60 for anyone born after 30 June 1964) applies only to your Member Benefit — the accumulation component built from your own contributions — not to the defined benefit pension.
