One of the most significant changes to super – the introduction of the transfer balance cap (TBC) – came into effect on 1 July 2017. It’s worth understanding how it is applied and how to take advantage of new opportunities when it’s increased.

As the name suggests, the TBC limits how much super can be transferred into a retirement phase pension account or another income stream for retirement using super money.

When you become eligible to access all your super you have the choice of withdrawing a lump sum, an income stream or a combination of both. If you open a retirement income stream, the income earned on the capital supporting that income stream is tax free.

The introduction of the TBC was designed to reinforce the role of super to provide retirement income, not as a store of intergenerational wealth or means of avoiding tax by placing a reasonable cap on the amount that can be invested in the tax-free retirement phase.

The transfer balance cap (TBC) and how it changes

On 1 July 2017, a cap on the amount that can be used to commence a pension in retirement phase was introduced. The cap was initially set at $1.6 million.

The cap is indexed periodically in $100,000 increments, in line with inflation. Most recently, the cap was indexed to $2 million from 1 July 2025, as shown in the table.

Date of indexation/introductionGeneral transfer balance cap

Need to know

The general TBC is used as a cap for some other super measures, so its indexation impacts the ability of individuals with high super balances to take advantage of those measures.

  • Your Total Super Balance (TSB) on 30 June must be under the general TBC to make non-concessional contributions or be eligible for a co-contribution in the following financial year.
  • Your spouse’s TSB must be under the cap on 30 June for you to claim a tax offset for contributions you make to their super in the following financial year.
  • You must have a TSB lower than the transfer balance cap less 2 x the non-concessional contribution cap to use the three-year bring-forward rule for non-concessional contributions.

How do the transfer balance cap rules work? 

The transfer balance cap limits the amount you can transfer into a retirement income stream, but any change in the value of the income stream after it has started is not taken into account. 

For example, if you transferred $1.7 million to an income stream in July 2022 you used the whole available cap at that time. If the balance of your account later rose above the cap due to investment returns, the limit would not be breached. Only transferring more money into an income stream can cause you to exceed the cap. 

If you exceed the cap, you are liable to pay tax on the excess transfer balance earnings (excess transfer balance tax). You also need to transfer any excess to a super accumulation account or withdraw it as a lump sum. This is called a commutation.

Need to know

Different rules exist for income streams that are ‘capped defined benefit income streams’. These are lifetime pensions paid from defined benefit funds, and certain pensions and annuities purchased prior to 1 July 2017.

Capped defined benefit income streams have a ‘special value’ calculated that is counted towards the transfer balance cap.

If the special value exceeds the transfer balance cap and the owner doesn’t have any income streams that are not capped defined benefits, then they will not exceed the cap or be liable for excess transfer balance tax. This is because these income streams cannot be cashed as a lump sum or transferred back into the accumulation phase, so there is no action the owner could take to avoid exceeding the cap.

Instead, additional tax is levied on payments from capped defined benefit income streams that are above the cap, as explained by the ATO.

Does this mean I can’t have more than my TBC amount in super?

No. You can have more than your cap in super, but you can only use the amount up to your cap to commence a retirement income stream.

If you have more than your transfer balance cap amount after retirement you can leave the remainder in your accumulation account. The fund pays 15% tax on earnings in the accumulation phase rather than 0% if it was in retirement phase. You can also remove it from the super system but, if the amount is then invested in your name, any income will be taxed at your personal tax rate.

What is a transfer balance account?

If you receive your super as an income stream, you will have a transfer balance account with the ATO. That account will start on either the date you first received a retirement income stream after 1 July 2017, or on that date if you were already receiving a retirement phase income stream on 30 June 2017.

A transfer balance account is a record of all the events that count towards your transfer balance cap and is kept by the ATO. If you have more than one super pension account, the amounts you used to commence each one (or the ‘special value’ of the income stream if it is a capped defined benefit) will all be recorded and added together in your transfer balance account report (TBAR) with the ATO. This account remains active until your death, and you can access your TBAR at the ATO via your myGov account.

If you already had a retirement income stream before 1 July 2017, your super fund was required to report the value as at 30 June 2017. If you commenced an income stream after 1 July 2017, your fund will have reported the commencement value of that super income stream. You can always talk to your super fund if you disagree with the amount reported on your TBAR.

If you take a lump sum from your income stream, or transfer some or all of it back into the accumulation phase, a debit is recorded in your transfer balance account. This creates ‘space’ in your account to be used when you later start another income stream.

The transfer balance cap is exceeded when the balance in your TBAR is higher than your personal cap.

A transfer balance account report will include both credits and debits as shown in this example:

What counts towards the transfer balance cap?

Any super transferred into retirement phase from an accumulation account to support an income stream counts as a credit towards the cap, as does the special value of any defined benefit pension you become entitled to.

Death benefit income streams also count as credits towards your cap. A death benefit income stream is an income stream started with the proceeds of a deceased person’s super, most commonly a spouse. Read more about consequences of receiving a death benefit income stream in the last section of this article.

Providing they meet certain criteria, as defined by law in the box below, structured settlement contributions do not count towards the cap. A credit and a debit for the structured settlement amount will appear in your TBAR on the same day. A structured settlement is a payment for a personal injury you have suffered that is contributed to a complying super fund.

“The contribution must arise from:

(a) The settlement of a personal injury claim that is based on the commission of a wrong, or a right created by statute, effected by a written settlement agreement between the parties

(b) Settlement of a personal injury claim arising under an Australian workers compensation law, or

(c) The order of a court made in respect of a claim that is based on the commission of a wrong, or a right created by statute (not including a court order approving or endorsing a settlement agreement as mentioned above).”

What happens if I breach the TBC?

If you breach the cap you may receive an excess transfer balance determination from the ATO. Regardless of whether you receive a determination you are required to pay tax on the excess transfer balance earnings for every day your account is in excess. Those earnings are calculated by a daily pre-determined formula, which is part of the law, and is worked out as follows:

90-day bank accepted bill yield + 7 percentage points ÷ number of days in the calendar year

The tax rate is 15% for your initial excess transfer balance amount, increasing to 30% for your next excess transfer balance amount, if you exceed the cap again.

The earnings compound daily and are credited to your transfer balance account and included in the next day’s earnings calculations. That only stops when the ATO issues an excess transfer balance determination (to crystallise the amount) or you commute the excess transfer balance by cashing it as a lump sum or transferring it back into an accumulation account; whichever is earliest.

If you don’t commute the amount by the required date on the determination, the ATO will send a commutation authority to your super fund to commute the amount even if the remaining amount is small.

What happens when the cap is indexed?

When indexation occurs, anyone who has not already commenced a retirement income stream has access to the new higher limit.

Individuals who have previously started an income stream have a personal transfer balance cap that is adjusted for indexation based on the proportion of the cap they have already used in the past.

If your transfer balance account has ever been equal to or higher than your cap, you will not receive any indexation.

Case study: Timing

In February 2025, Jeremy retired with a super balance of $2.1 million. He had never previously had an income stream.

Jeremy started an account-based pension with $1.9 million, the maximum amount under the 2024-25 transfer balance cap.

When the cap was indexed in July, Jeremy was not able to transfer any more of his super balance into an income stream because he had already used 100% of the cap.

Closing his existing pension and transferring it back into the accumulation phase will not reset his entitlements. Jeremy’s cap is frozen at $1.9 million.

If Jeremy had put off starting his income stream until July 2025, he would have become entitled to the new $2 million cap because he had not previously used any of the cap. He could have then transferred $2 million into his pension, enjoying an additional $100,000 invested in the tax-free retirement phase.

Indexation is calculated by dividing the highest ever balance of your transfer balance account by your transfer balance cap on the earliest day you had that balance. That number is then expressed as a percentage, rounded down to the nearest whole number, and subtracted from 100. The resulting percentage of the indexation increment is then added to your prior cap.

Confused? Luckily, you will not need to calculate this for yourself. The ATO keeps your personal cap up to date with indexation in their online service you can access via myGov. If you’re keen to understand it, here’s how it works.

Case study: How to work out your new transfer balance cap

Marlene started a retirement income stream with a value of $1.2 million for the first time on 1 November 2021. At the time the transfer balance cap was $1.7 million.

When the cap was indexed on 1 July 2023, her new cap was calculated as follows:

  • $1.2 million / $1.7 million = 0.706 or 70.6% (this is rounded down to 70%)
  • 100% – 70% = 30%
  • 30% of $200,000 = $60,000
  • Marlene’s cap after 1 July 2023 indexation was $1.7 million + $60,000 = $1.76 million

In May 2025, Marlene transferred an additional $300,000 into a second retirement income stream. This created a credit of $300,000 transfer balance account, bringing its total to $1.5 million. This is the new highest balance in her TBA and her personal cap on the day was $1.76 million due to the prior indexation

When the cap was indexed on 1 July 2025, her new cap was calculated as follows:

  • $1.5 million / $1.76 million = 0.852 or 85.2% (this is rounded down to 85%)
  • 100% – 85% = 15%
  • 15% of $100,000 = $15,000
  • Marlene’s cap after 1 July 2025 indexation is $1.76 million + $15,000 = $1.775 million

It’s important to remember that if there are transfer balance events that reduce the amount supporting your pension – for example the pension was partially commuted – your indexation will depend on the highest ever balance of your TBA.

Death and the transfer balance cap

When you inherit a death benefit income stream its value is added to your transfer balance account. The timing of the addition depends on whether it is reversionary or non-reversionary.

When a person who held an income stream and had nominated a reversionary beneficiary dies, the ownership of the income stream automatically passes to the reversionary beneficiary and a reversionary death benefit income stream starts.

In this case, the value on the day of death is calculated and a credit of that amount is made to the transfer balance account of the recipient 12 months after the death. This delay provides time for the beneficiary to make adjustments if necessary to avoid exceeding the cap.

A non-reversionary death benefit income stream is an income stream commenced with super death benefits when there was no reversionary nomination. The account may have been in accumulation phase or in a retirement income stream without a reversionary nomination.

In this case, a credit to the recipient’s transfer balance account of the value of the death benefit income stream occurs on the day it commences.

If you inherit a super death benefit as a lump sum, there are no consequences for your transfer balance cap.

Case study: Reversionary pension

Mary and Geoff, married for 40 years, began retirement income streams with $1 million each in August 2021, nominating each other as reversionary beneficiaries.

Geoff passed away in June 2025 and Mary became entitled to the reversionary pension. The balance of Geoff’s account at the time was $900,000. This value will be credited to Mary’s transfer balance account in June 2026.

Mary’s transfer balance cap was increased to $1,826,000 on 1 July 2025 because of proportional indexation.

If Mary does nothing, the total balance in her transfer balance account after the credit from Geoff’s reversionary pension will be $1,900,000, which will exceed her cap of $1.826 million and make her liable for excess transfer balance tax.

To avoid this, Mary can transfer the excess amount of $74,000 from her original pension back into an accumulation account, or cash it as a lump sum. This will cause a corresponding debit to her transfer balance account, removing the risk of exceeding the cap.

When a child receives a death benefit income stream their transfer balance cap is not the general cap. Instead, they have a ‘modified personal transfer balance cap’.

The modification of the transfer balance cap depends on the deceased parent’s super interests – that is, whether they were in accumulation or retirement mode – and the child dependent’s share of the super interests. These modification calculations are called cap increments.

A child recipient of a death benefit income stream must cash it when they reach age 25 unless they are disabled. At the time benefits are cashed, the modified transfer balance cap arrangements end. The rule for child recipients are complex and described in detail on the ATO website – scroll down to ‘child recipients of a death benefit income stream’.

    If you move your pension back into accumulation and then later covert back to a pension is that money counted twice ?

      When money is transferred back into accumulation phase, this is called a commutation. The commutation is deducted from your transfer balance account, reducing its balance.
      Then, when you transfer money back into a pension (retirement phase), the amount transferred is added to your transfer balance account.
      This avoids any double counting.
      The process is explained under the heading ‘What is a transfer balance account?’ in this article.

  2. A word of warning – don’t expect any help from your super fund in dealing with the nuances of Transfer Balances. My experience with HostPlus and Aust Super was that their support people have been told to freeze at the mention of “transfer balance” and start repeating “ATO, ATO, ATO” until you hang up. So not only did I find myself grappling with the verbose and confusing info from the ATO, but no assistance from the Super Funds who appear to be paralysed by the new transfer balance system. My independent financial advisor at least was helpful.
