You have spent years contributing to super, and you have probably heard the term transfer balance cap thrown around. What does it actually do, and why does it matter to someone who is still building a portfolio now rather than winding down?
The short answer: the cap decides how much of your super can sit in a tax-free environment in retirement. Every dollar above it stays in accumulation, where earnings are taxed at 15%. That difference compounds over a long holding period, and property inside an SMSF makes the numbers very concrete.
What the cap is and how it has moved
The transfer balance cap (TBC) limits the total amount of superannuation that can be transferred from the accumulation phase, where earnings are taxed at 15%, into the retirement phase, where earnings are tax-free.
It was originally set at $1.6 million when introduced on 1 July 2017 and is indexed in $100,000 increments in line with CPI. The post title references $1.9 million because that was the general cap for the 2023-24 and 2024-25 financial years. Since then the cap has moved. The general transfer balance cap was indexed by $100,000 to $2 million from 1 July 2025. Per the ATO (ato.gov.au), indexation of the general TBC will occur again on 1 July 2026, increasing the cap by $100,000 from $2 million to $2.1 million.
Your personal cap is not always the same as the general cap. Your personal transfer balance cap depends on when you first started a retirement-phase pension and how much of the cap you have used. If you have ever fully used your transfer balance cap, you are not eligible for future indexation increases. In ATO online services you can view your personal transfer balance cap and your transfer balance account, which records all the debits and credits that make up your balance.
The tax trade-off: accumulation versus pension phase
The cap matters because of what happens on either side of it.
In accumulation phase, the fund's net income, which includes investment income like dividends, interest, and rent, is generally taxed at a flat 15% rate. For capital gains, if an asset is held for more than 12 months, any realised capital gain is eligible for a discount of one-third, resulting in an effective tax rate of 10%. Per the ATO (ato.gov.au), complying SMSFs are entitled to a CGT discount of one-third if the relevant asset had been owned for at least 12 months.
In pension phase, the picture shifts entirely. Once members start a retirement-phase pension, the entire fund, or allocated portion, becomes tax-exempt. No CGT discount is needed because there is zero tax on sale proceeds, rental income, or dividends.
If you exceed your cap, you must commute the excess, and the ATO will apply an excess transfer balance tax at 15% for the first breach and 30% for subsequent breaches, plus notional earnings on the excess. That is a penalty worth avoiding, which is why planning ahead of retirement matters.
How contributions interact with the cap
The cap does not sit in isolation. It connects directly to what you can contribute in the years before retirement.
For 2025-26, the rules are as follows, per the ATO (ato.gov.au):
- The concessional (before-tax) contributions cap is $30,000 for 2025-26. This includes any Superannuation Guarantee contributions made by your employer, as well as any salary sacrifice amounts.
- The non-concessional contributions cap for 2025-26 is $120,000. This means you can contribute up to $120,000 of after-tax money to your super fund in a financial year.
- If your total super balance is equal to or more than the general transfer balance cap at the end of the previous financial year, your non-concessional contributions cap is nil for the current financial year.
The bring-forward rule gives eligible members more room. Depending on your total superannuation balance last 30 June, you may be eligible to bring forward up to two financial years' non-concessional contribution caps, effectively allowing you to contribute up to $360,000 in one go. Both the concessional and non-concessional caps are rising from 1 July 2026. The concessional contributions cap will increase to $32,500 from 1 July 2026, and the non-concessional contributions cap will also rise to $130,000.
A worked example: property inside an SMSF across phases
Consider an SMSF in accumulation phase that holds a residential investment property purchased for $700,000. The fund earns net rental income of $28,000 in a financial year. At the 15% accumulation rate, the tax payable on that income is $4,200. If the same fund were entirely in pension phase, that same $28,000 would attract zero tax.
Now suppose the property is sold seven years after purchase for $1,050,000, producing a $350,000 capital gain. In accumulation phase, the one-third CGT discount reduces the taxable gain to approximately $233,000, and tax at 15% comes to around $35,000. In pension phase, the same sale produces no CGT liability at all.
This is an illustrative scenario only. It does not account for costs, LRBA interest, fund expenses, or any other member contributions. The outcome in any real fund will differ. What it does show is why the timing of the transfer relative to the cap matters, and why maximising the amount you move into pension phase before or at retirement is a consideration worth raising with a licensed adviser.
Note also that any amount above the TBC must remain in accumulation phase or be withdrawn from the super system. You are only permitted to move up to the TBC into the tax-free pension phase. Any amount exceeding this cap must remain in the accumulation phase, where it continues to be taxed at 15%, or be withdrawn from the super system entirely.
What to think about next
If you are in your 30s, 40s, or 50s and building super alongside a property strategy, the transfer balance cap is a number worth tracking over time. Here are three practical steps:
- Check your personal TBC now. Individuals can view their personal TBC in ATO online services through myGov. It takes a few minutes and tells you exactly where you stand.
- Talk to an SMSF specialist accountant about how your current super balance, expected contributions, and any existing SMSF property interact with the cap by the time you reach retirement. The rules around proportional indexation and excess transfer balance tax are detailed, and the numbers are specific to each member's situation.
- Connect with a licensed financial adviser to understand whether an SMSF structure with a property component fits within your broader plan, taking into account contribution caps, liquidity requirements, and the phase of the fund at the time of any asset sale.
If you want to understand how property fits into an SMSF or what the finance options look like, the team at Elite Wealth Creators can walk you through the structure and connect you with the relevant licensed specialists. You can explore our services, read more on the insights blog, or book a call to start the conversation.
