Many SMSF trustees assume that retirement pension rules remain unchanged once a pension begins. However, several aspects of the system can change over time or apply differently between members, creating areas where trustees may encounter unexpected outcomes.

The general transfer balance cap increased to $2.1 million from 1 July 2026, but not every member receives the same increase. Understanding how indexation works, why personal caps differ and how reversionary pensions are treated can help SMSF trustees manage retirement phase arrangements more effectively.

Indexation moves the goalposts

The transfer balance cap limits how much a person can transfer into retirement phase, where eligible Earnings may receive concessional tax treatment.

The general transfer balance cap is not fixed permanently. It is indexed in increments of $100,000 in line with changes in the consumer price index.

The general cap has increased over time from $1.6 million when the system began, followed by increases to $1.7 million, $1.9 million, $2 million from 1 July 2025 and $2.1 million from 1 July 2026.

These increases affect members who have not yet started retirement phase pensions or those who still have unused transfer balance cap space.

However, the headline general cap does not automatically apply to every member. A person’s own transfer balance history determines the personal cap that applies to them.

Why personal caps differ

Each member has an individual transfer balance cap based on their own retirement phase history.

A person who started a pension when the general transfer balance cap was lower may have a personal cap based on the earlier amount, with adjustments depending on how much of the cap they had used.

Members who have fully used their transfer balance cap generally do not receive further indexation. In contrast, members who have used only part of their available cap may receive some proportional increase.

This means two members with similar balances and the same age may have different personal transfer balance caps because their pension commencement history differs.

The key point for trustees is that the current general transfer balance cap of $2.1 million does not necessarily represent the amount every member can move into retirement phase.

The ATO tracks each member’s transfer balance account, and the personal transfer balance cap is the relevant figure for determining available capacity.

Proportional indexation explained

The difference between members occurs because of proportional indexation.

When the general transfer balance cap increases, a member’s personal cap is adjusted based on the unused portion of their cap at the relevant time.

For example, consider a hypothetical member who had previously used 80% of their transfer balance cap. When indexation applies, only the remaining 20% portion is considered for the increase.

A member who had not used any of their cap would generally receive the full benefit of the increase.

This example is hypothetical and only explains the proportional indexation method.

The practical effect is that members who have already used a large portion of their retirement phase capacity may receive a smaller benefit from future indexation compared with members who have not yet started a pension.

Reversionary pensions and timing traps

Reversionary pensions are another area where SMSF trustees may encounter unexpected outcomes, particularly after the death of a member.

A reversionary pension is an income stream that automatically continues to a nominated beneficiary, commonly a spouse, after the original pension member dies.

When a pension reverts, a Credit generally arises in the surviving beneficiary’s transfer balance account. However, special timing rules apply, and the credit is generally counted 12 months after the date of death.

This timing provides the beneficiary with an opportunity to review their retirement phase position and make adjustments if required.

A key consideration is that the amount counted is generally based on the value of the pension at the date of death rather than the value when the transfer balance account is adjusted.

If the surviving spouse already has their own pension, the combined balances may exceed their personal transfer balance cap. In that situation, adjustments such as commuting part of a pension may be required to manage the excess.

What trustees should check

Trustees can reduce the risk of unexpected pension issues by reviewing each member’s personal transfer balance cap rather than relying only on the general cap.

Important areas to check include:

  • how much of each member’s transfer balance cap has been used;
  • whether future indexation applies to the member;
  • whether pension arrangements are reversionary;
  • who is nominated as a reversionary beneficiary;
  • how death benefit pensions may affect the surviving beneficiary’s transfer balance position.

Keeping pension documentation updated and understanding how each member’s circumstances affect their cap can help avoid future compliance issues.

What to watch next

With the general transfer balance cap now at $2.1 million, future indexation may continue to create differences between members who have used their retirement phase capacity and those who have not.

The introduction of Division 296 from 1 July 2026 also increases the importance for some members of understanding how their Superannuation balances are measured.

Trustees with larger balances or complex pension arrangements may need to review how retirement phase balances interact with broader superannuation settings.

Key Insights

SMSF pension rules can create unexpected outcomes because they are based on individual circumstances rather than a single universal limit.

The general transfer balance cap, personal cap calculations, proportional indexation and reversionary pension rules all influence how much a member can hold in retirement phase.

Trustees who understand their members’ personal positions and review pension arrangements regularly can better manage the risk of excess transfer balance issues and unexpected tax outcomes.
