The transfer balance cap rose to $2.1 million on 1 July. Most trustees will not get the full increase

The general transfer balance cap indexed from $2.0 million to $2.1 million on 1 July 2026. If you have already started a retirement-phase pension, the odds are strong that your own cap did not move by the full $100,000, and it may not have moved at all. The increase is proportional, and the proportion is personal to you.

This is the number that governs how much of a member's superannuation can sit in the retirement phase, where fund earnings are untaxed. It is worth being exact about, because a trustee who assumes the headline figure is theirs can commence a pension that breaches their real cap. An excess transfer balance carries its own tax and a mandated commutation of the excess back to accumulation, which is a fair amount of paperwork to generate from a rounding assumption.

Two members, two different caps

There are two starting positions, and they diverge sharply.

A member who has never held a retirement-phase income stream has never had a transfer balance account. Their personal cap is simply the general cap on the day they first start a pension. Anyone commencing their first pension on or after 1 July 2026 gets the full $2.1 million.

A member who already has a transfer balance account is on the proportional track. Their cap was set when they first entered the retirement phase, and each later indexation lifts it only by the share of the cap they had left unused. Two neighbours who both started pensions years ago, and who both read the same $2.1 million headline this month, can have personal caps that are hundreds of thousands of dollars apart.

How the proportion is worked out

The Australian Taxation Office looks at the highest balance your transfer balance account has ever reached, and expresses it as a percentage of the general cap that applied at that time. What is left over is your unused cap percentage, and that percentage is what every future indexation event applies to.

Suppose your account's highest ever balance used 60 percent of the general cap in force at the time. The unused 40 percent is your indexable share. This year's $100,000 general increase lifts your personal cap by 40 percent of $100,000, which is $40,000. A member whose highest balance used only 20 percent of the cap indexes on the other 80 percent, and gets $80,000 of the increase.

Two details shrink the benefit rather than grow it. The unused percentage is rounded down to the nearest whole number before it is applied. And a member who once filled their cap completely has an unused percentage of zero, so no indexation, this year or any year, moves their cap at all. It stays wherever it was set when they first entered the retirement phase.

The number to trust is the ATO's

Because the calculation depends on a balance and a cap from some earlier year, it is not one most trustees can reconstruct reliably from memory. The figure that governs you is the personal transfer balance cap shown in ATO online services, reachable through myGov. That is the number to check before commencing or increasing a pension, not the general cap in the newspaper.

We set out the general cap alongside the other figures that moved this year at smsfcore.com/blog/smsf-changes-1-july-2026-six-numbers.

Why a report due this month decides your cap

Here is the part that turns this from background reading into a July task. The ATO derives your personal cap, and your indexation entitlement, from the transfer balance account events your fund has reported. An event that was reported late, or with the wrong value, or not at all, feeds a wrong cap straight into your myGov figure.

Since 1 July 2023 every SMSF reports transfer balance events quarterly, within 28 days of the end of the quarter, whether or not any member is near the cap. The June 2026 quarter is due on 28 July 2026. If a member commenced, commuted or partly commuted a pension in that quarter, or if an earlier event was never lodged, this is the window to get it recorded before the indexation calculation reads stale data. The cap the ATO shows you is only as accurate as the events it has been told about.

The same number, a different job

The $2.1 million general cap does more than one job this year, which is a common source of confusion. It also sets the non-concessional bring-forward tiers, tested against a member's total super balance at the prior 30 June. That is a different test on the same headline number, and we cover it separately at smsfcore.com/blog/bring-forward-tiers-fy2026-27.

What we track

SMSF Core carries each member's balance against the caps and the Division 296 thresholds, with the ATO source cited on every figure it holds, so the general cap and the member-specific tests do not get conflated. There is a sample fund at app.smsfcore.com/demo if you want to see the member view with data already in it.

SMSF Core is an information tool, not a licensed financial service. Your personal transfer balance cap depends on your own history. Confirm it in ATO online services and talk to a licensed adviser or your accountant before acting.
