In short

Commuting a pension to accumulation and re-commencing after the transfer balance cap indexes doesn't unlock extra cap space for members who ever fully used their personal TBC. Section 294-40 measures unused cap percentage against the highest-ever transfer balance account balance, not the current one, so once a member hits 100% usage, that 0% unused position is locked in permanently regardless of later commutations.

For Australian retirees with substantial super balances who fully consumed their personal transfer balance cap (TBC) at pension commencement, a strategy known in some commentary as the "pension reset" is sometimes proposed as a way to capture additional cap space from future indexation events. The proposed mechanism is straightforward at first glance: commute some or all of the pension back to accumulation, wait for the General TBC to step up at the next indexation event, then re-commence pension at the higher cap level. The intuition appears sound — by reducing the transfer balance account (TBA) balance through commutation, the member should be entitled to proportional indexation on the now-unused portion. The trouble is that this isn't how the indexation framework actually works. The proportional indexation rules in section 294-40 of the Income Tax Assessment Act 1997 (https://classic.austlii.edu.au/au/legis/cth/consol_act/itaa1997240/s294.40.html, accessed 13 May 2026) measure the unused cap percentage by reference to the highest-ever TBA balance, not the current balance. Once a member has used 100% of their personal TBC at any point, that 100%-used position is locked in for indexation purposes — subsequent commutations don't restore unused-percentage eligibility. The strategy as commonly described does not deliver additional cap space from future indexation, and the practitioner advising high-balance clients needs to surface this clearly to avoid building expectations that the law won't support (ATO — transfer balance cap, https://www.ato.gov.au/individuals-and-families/super-for-individuals-and-families/in-detail/transfer-balance-cap, accessed 13 May 2026).

The TBC indexation framework under Subdivision 294-D operates by reference to CPI in $100,000 increments. The General TBC began at $1.6 million on 1 July 2017 when the framework commenced, indexed to $1.7 million on 1 July 2021, to $1.9 million on 1 July 2023, and to $2.0 million on 1 July 2025 (ATO — key super rates and thresholds, https://www.ato.gov.au/rates/key-superannuation-rates-and-thresholds/?anchor=Generaltransferbalancecap, accessed 13 May 2026). Personal TBCs index proportionally based on the member's unused cap percentage. Section 294-40(3) defines that unused cap percentage by reference to the highest balance the member's transfer balance account has ever had relative to the applicable personal TBC at that time — the higher the historic peak (as a percentage of cap), the lower the unused cap percentage and the smaller the proportional indexation uplift. A member who used 60% of their personal TBC at commencement and never went higher has 40% unused; when the General TBC steps up by $100,000, their personal TBC increases by 40% × $100,000 = $40,000. A member who at any point reached 100% of their cap has 0% unused — proportional indexation produces zero increase regardless of subsequent commutations.

The highest-ever measurement is the legislative feature that closes off the "reset" workaround. When the TBC framework was being designed, this issue was specifically considered, and the proportional indexation was anchored to highest-ever rather than current balance precisely to prevent the cycle the strategy attempts. A member who fully consumed their cap, then commutes back to accumulation, has reduced their current TBA balance under section 294-80 (https://classic.austlii.edu.au/au/legis/cth/consol_act/itaa1997240/s294.80.html, accessed 13 May 2026) — the commutation is a TBA debit. But their highest-ever balance, recorded in their transfer balance account history, is unchanged. The "unused cap percentage" under s.294-40 looks back to that historic peak when calculating the indexation factor, so the reduced current balance doesn't help. Re-commencing the pension after indexation simply uses the same personal TBC the member had before — there is no additional pension cap space to capture.

The practical implication for high-balance retirees who fully consumed their personal TBC is that the personal cap is permanently set at whatever level it was at when 100% consumption first occurred. A member who commenced a pension in July 2017 at the $1.6 million general TBC level, fully consuming their cap, has a personal TBC fixed at $1.6 million — and no amount of subsequent commutation and re-commencement will increase that. The general TBC indexations to $1.7m, $1.9m, $2.0m have not flowed through, and won't, because the highest-ever percentage stays at 100%. The same applies to members who commenced at $1.7m in 2021 fully consuming the then-current TBC — their personal TBC remains at $1.7m.

For high-balance retirees, the strategies that actually work are different from the reset misconception. Partial consumption at commencement is the key timing decision — members who commenced with less than 100% of cap used continue to benefit from proportional indexation on the unused portion, capturing real additional space at each step-up. Members planning pension commencement in coming years can structure the timing so that some headroom is retained for future indexation capture. Spousal allocation can spread balances across two members' personal TBCs, with each spouse's cap operating independently — for couples where one spouse's TBC is fully consumed, contributing to the other spouse's super (within NCC rules) and commencing additional pension in their name can use their unused cap headroom and their separate indexation entitlement. Accumulation-phase retention of additional balance, accepting the 15% earnings tax in accumulation rather than the 0% pension-phase rate, is sometimes the right answer when no further cap space is available — the alternative is to leave the money outside super in personal name where the marginal rate may be higher than 15%. The economic comparison depends on the member's other income and the long-term tax differential.

The commutation-for-balance-management scenarios that legitimately involve TBA debits are different from the reset misconception. Excess transfer balance — where post-indexation increases in the General TBC don't apply to a member who's already over their personal TBC for some reason — requires commutation to bring the TBA balance within cap. Death benefit pension commutation — where a reversionary pension to a surviving spouse needs commutation to fit within the spouse's TBC — involves real TBA reductions. Investment portfolio restructuring — where commutation is part of moving assets between accumulation and pension phases — involves TBA debits with consequent considerations under s.295-387 (the disregarded small fund assets rule covered at articles/2026-05-04-smsf-actuarial-certificate-pension-exemption for SMSFs). These are legitimate uses of commutation; none of them produces additional cap space through the indexation mechanism.

A specific cohort worth flagging is the 2017 transitional pension cohort — members who commenced pensions before 1 July 2017 with substantial pension balances at the transition. Their personal TBC was set based on the pension value at 30 June 2017 under the transitional rules, with subsequent indexation rules applying. For pre-2017 members who fully consumed their initial cap at the transition (TBA balance at 30 June 2017 ≥ $1.6 million), the same highest-ever-percentage logic applies — they don't benefit from subsequent General TBC indexations. The framework treats all members consistently: fully-used at any historic point means zero unused cap percentage for proportional indexation purposes.

For practitioners advising high-balance clients, the conversation needs to be honest about what's achievable. The reset strategy as sometimes circulated is not effective. The strategies that actually work for high-balance retirees are limited to partial consumption planning before commencement (where still possible), spousal allocation across two caps, and accepting accumulation-phase retention for balance above the cap with its 15% earnings tax. None of these unlock additional pension cap from future indexation for a member who's fully used their cap. The honest framing prevents clients building expectations that the law won't support, and focuses the planning conversation on what genuinely produces value.

The broader integration with retirement planning is what matters in practice. The pension serves multiple objectives — income, tax efficiency, estate planning, intergenerational wealth transfer. For high-balance retirees with fully-used TBC, the focus shifts from cap optimisation (which has run its course) to: accumulation-phase investment strategy, estate planning around super death benefits (BDBN coordination, components proportioning under s.307-125 covered at articles/2026-05-04-pension-proportioning-rule-tax-free-lock-in), and broader portfolio management. The constrained TBC framework means high-balance retirees can't grow their tax-exempt pension footprint, but they can manage the residual accumulation-phase super and the broader retirement portfolio with the constraints accepted.

What do worked planning examples show?

These two cases show how the actual TBC indexation framework plays out for high-balance scenarios. Illustrative only — not personal advice — using FY25-26 figures.

Case 1 — Robert, 65, fully consumed his personal TBC of $1.6 million at pension commencement in July 2017. General TBC has indexed to $2.0 million since but Robert's personal TBC has stayed at $1.6 million due to the 100% historic consumption. He's wondering whether commuting $500,000 back to accumulation now, waiting for the next General TBC indexation, and re-commencing pension would capture additional cap space. On these facts, the rational analysis is that this strategy does not work. Robert's "unused cap percentage" under s.294-40 is fixed at 0% because his highest-ever TBA balance reached 100% of his personal TBC at commencement. Subsequent commutation reduces his current TBA balance, but the "highest ever" is unchanged. When the next General TBC step-up occurs, Robert's personal TBC indexes by 0% × $100,000 = $0. Re-commencing the pension after commutation simply puts the same money back into pension phase at the same personal TBC level he had before. The strategy doesn't unlock additional pension cap. The trap to avoid is incurring the operational cost (12 months of accumulation tax on $500,000 ≈ $4,500 on 6% earnings) for a benefit that doesn't materialise. Robert's honest planning conversation accepts the $1.6 million personal TBC limit and focuses on accumulation-phase management of any super above that level.

Case 2 — Margaret and David, both 64. Margaret has $2.3 million in super; David has $400,000. They're planning pension commencement. On these facts, the rational pathway is spousal allocation rather than reset. Margaret can commence pension up to her personal TBC of $2.0 million (FY25-26), leaving $300,000 in accumulation. Through NCC contributions to David (up to his cap and bring-forward depending on his TSB position), some of Margaret's super can be moved to David and commenced as his pension, using David's separate personal TBC. The couple can collectively support two pensions totalling up to $4.0 million in retirement phase (each $2.0m). The cost of moving funds (CGT on personal-name assets if relevant, fund transfer mechanics) needs to be modelled, but the structural ceiling is much higher than the single-spouse path. The trap to avoid is treating Margaret's TBC as the binding constraint when David's separate cap is available — the spousal allocation is the legitimate planning lever, not the reset misconception.

For Australian retirees with substantial super balances, the TBC indexation framework under Subdivision 294-D ties proportional indexation to the highest-ever TBA balance percentage. Members who fully consumed their personal TBC at any historic point have zero unused cap percentage and don't benefit from subsequent General TBC indexations. The commonly-circulated "pension reset" strategy — commute to accumulation, wait for indexation, re-commence — does not unlock additional pension cap space because the highest-ever measurement is sticky. The strategies that actually work are partial consumption planning before commencement (where still possible), spousal allocation across two caps, and acceptance of accumulation-phase retention for excess balance. For practitioners advising high-balance clients, honest framing of what the law allows is the foundation of credible advice.

Key takeaways

  • Under s.294-40, a member's personal transfer balance cap indexes proportionally based on their unused cap percentage, which is measured against the highest-ever balance their transfer balance account has reached, not their current balance.
  • A member who has ever used 100% of their personal TBC has a permanently fixed 0% unused cap percentage, so subsequent commutations and re-commencements produce zero additional indexation, regardless of how many times the general TBC steps up afterwards.
  • Genuine reasons for commutation — excess transfer balance correction, a reversionary pension exceeding the surviving spouse's cap, or portfolio restructuring — are legitimate, but none of them creates additional cap space through the indexation mechanism.
  • The strategies that actually deliver extra cap space are partial cap consumption at initial commencement (preserving headroom for future indexation), spousal allocation of super across both partners' separate personal TBCs, and accepting accumulation-phase retention (at 15% earnings tax) for balances above the cap.
  • The 2017 transitional pension cohort, whose personal TBC was set from their pension balance at 30 June 2017, is subject to the same rule — those who fully consumed their cap at that transition also don't benefit from later general TBC indexation.

Frequently asked questions

Can I unlock more transfer balance cap space by commuting my pension and restarting it?

No, if you've ever used 100% of your personal transfer balance cap. Under s.294-40, your unused cap percentage is fixed by the highest-ever balance your transfer balance account has reached, not your current balance after commutation, so re-commencing simply restores the same personal cap you had before.

Why doesn't my personal transfer balance cap increase when the general cap indexes?

If you fully consumed your personal cap at any point in the past, your unused cap percentage is locked at 0%, so proportional indexation — calculated as your unused percentage multiplied by the general cap's increase — produces zero additional space for you, even as the general cap rises over time.

What strategies actually give high-balance retirees more transfer balance cap space?

Structuring pension commencement to retain some unused cap headroom from the start (if not yet commenced), allocating super across both spouses' separate personal caps rather than concentrating it in one, and accepting that balances above the cap remain in accumulation phase paying 15% earnings tax, since there's no legitimate way to expand a fully-used personal cap.

Are there legitimate reasons to commute a pension back to accumulation?

Yes — correcting an excess transfer balance, adjusting a reversionary pension to fit within a surviving spouse's cap, or restructuring an investment portfolio between accumulation and pension phase are all legitimate uses of commutation. None of them, however, creates additional cap space through the indexation mechanism for a member who has already fully used their cap.
