The $1.9M Transfer Balance Cap: How to structure super when you're a high-balance member

If your superannuation balance is approaching or exceeding $1.9 million, you are in a fortunate position — but also one that demands careful planning. The transfer balance cap (TBC) determines the maximum amount you can move from the accumulation phase into the tax-free retirement (pension) phase of superannuation. Get it wrong, and you face excess transfer balance tax, potential penalties, and a less efficient retirement income structure.

For high-balance members, the TBC is not just a number to be aware of. It is the centrepiece around which your entire retirement strategy should be designed — particularly if you are part of a couple with uneven super balances.

What Is the Transfer Balance Cap?

The transfer balance cap was introduced on 1 July 2017 as part of the government's superannuation reforms. It places a limit on the total amount of superannuation that can be transferred into the retirement phase, where investment earnings are tax-free. The general TBC is currently $1.9 million (indexed from the original $1.6 million in $100,000 increments, linked to CPI).

Every individual has their own personal transfer balance cap. If you commenced a retirement-phase pension before 1 July 2017, your personal cap may be lower than $1.9 million, because indexation is proportional — it is based on the highest percentage of your cap you have ever used, not the dollar amount.

Accumulation Phase vs Pension Phase: Why It Matters

The distinction between accumulation and pension phase is one of the most consequential in superannuation. In the accumulation phase, your fund's investment earnings are taxed at up to 15% (with the effective rate often lower due to franking credits, the CGT discount, and tax-exempt income). In the pension phase, those same investment earnings are completely tax-free.

On a $1.9 million balance earning 7% per annum, the difference amounts to roughly $20,000 per year in tax savings within the pension phase. Over a 20-year retirement, that is a material sum — potentially $400,000 or more in additional wealth, before compounding is factored in.

This is precisely why the government introduced the cap. Without it, individuals with very large super balances could shelter millions of dollars from tax indefinitely. The TBC strikes a balance: generous tax concessions up to $1.9 million, with standard superannuation taxation applying to any amount above that threshold.

Strategies for Couples: The Power of Balance Equalisation

For couples, the TBC creates one of the most compelling planning opportunities in Australian superannuation. Each individual has their own $1.9 million cap, meaning a couple can collectively hold up to $3.8 million in the tax-free pension phase.

The challenge is that many couples have uneven super balances. It is common to see one partner with $2.5 million in super and the other with $400,000. Without intervention, the higher-balance member is forced to leave $600,000 or more in the accumulation phase, paying tax on earnings that could otherwise be sheltered.

Contribution Splitting

One of the simplest equalisation strategies is contribution splitting. Each year, you can split up to 85% of your concessional (before-tax) contributions with your spouse. This is particularly effective over a 5–10 year period leading into retirement, gradually building the lower-balance spouse's account while reducing the higher-balance spouse's accumulation.

Spouse Contributions

If one spouse earns less than $40,000 per year, the higher-earning spouse can make a non-concessional contribution of up to $3,000 into the lower-earning spouse's super and receive an 18% tax offset (up to $540). While the tax offset is modest, the real benefit is directing capital to the spouse with more available TBC room.

Re-contribution Strategies

For members already in retirement, the withdrawal-and-recontribution strategy can be powerful. The higher-balance member withdraws a lump sum from their pension account (a debit to their transfer balance account), and the lower-balance spouse contributes that amount as a non-concessional contribution into their own super — subject to their non-concessional contributions cap ($120,000 per year, or up to $360,000 under the bring-forward rule if under age 75 and eligible).

"For couples with combined super above $3.8 million, the question is not whether to equalise — it is how quickly and efficiently you can get there. Every year of delay costs real dollars in unnecessary tax."

Exceeding the Transfer Balance Cap

If you transfer more than your personal TBC into the pension phase, the ATO will issue you with a determination requiring you to commute (move back to accumulation) the excess amount. But the consequences do not stop there.

The excess transfer balance earnings are subject to additional tax. For a first-time breach, the tax rate is 15% on the notional earnings attributable to the excess amount. For subsequent breaches, the rate rises to 30%. The notional earnings are calculated using the general interest charge (GIC) rate, not your actual investment returns — which means even if your fund earned less, you may be taxed as though it earned more.

Tax Implications for High-Balance Members

For members with super balances above $1.9 million, the tax landscape is multi-layered. Here is what you need to consider:

• Division 296 tax: From 1 July 2025, individuals with total super balances above $3 million will face an additional 15% tax on earnings attributable to the portion above $3 million. This tax applies to unrealised gains, making it a significant consideration for members with large illiquid holdings.
• Accumulation phase tax: Any super balance above your TBC remains in accumulation, where earnings are taxed at up to 15%. Effective tax planning — including asset allocation and the use of franking credits — can reduce this effective rate to well below 15%.
• Death benefit taxation: Super balances paid to non-dependants (typically adult children) upon death are taxed on the taxable component at up to 17% (15% plus Medicare levy). Structuring your super to maximise the tax-free component can save your beneficiaries tens of thousands of dollars.
• Non-concessional cap interaction: If your total super balance exceeds $1.9 million, you cannot make any non-concessional contributions. This is measured on 30 June of the prior financial year, so a well-timed withdrawal strategy may restore contribution eligibility.

Re-contribution Strategies: Optimising the Tax-Free Component

One of the most overlooked strategies for high-balance members involves optimising the tax-free and taxable components of your super. When you withdraw a lump sum from super (which comes out proportionally as tax-free and taxable) and re-contribute it as a non-concessional contribution, the entire re-contributed amount becomes tax-free component.

This matters most for estate planning. If your super is paid as a death benefit to a non-dependant, only the taxable component is subject to tax. By progressively converting your taxable component to tax-free through re-contribution strategies, you can significantly reduce the tax burden on your beneficiaries.

Example: The Re-contribution Strategy in Practice

David, aged 67, has $1.8 million in super. His tax-free component is $300,000 and his taxable component is $1.5 million. He withdraws $360,000 as a lump sum (proportionally $60,000 tax-free and $300,000 taxable, both tax-free to him as he is over 60). He then re-contributes the $360,000 as a non-concessional contribution over three years using the bring-forward rule. The result: his tax-free component increases from $300,000 to $600,000, and his taxable component drops from $1.5 million to $1.2 million — a potential tax saving for his adult children of approximately $51,000 on his death.

Practical Steps for High-Balance Members

If your super balance is approaching or has exceeded the transfer balance cap, here is a structured approach to getting your affairs in order:

1. Check your personal transfer balance cap via myGov. Do not assume it is $1.9 million — if you commenced a pension before indexation, your cap may be lower.
2. Model the couple strategy. If you have a spouse, map out both balances and determine the optimal split to maximise combined pension-phase assets.
3. Review your tax components. Understand the tax-free and taxable split of your balance. If estate planning is a priority, explore re-contribution strategies.
4. Consider Division 296 exposure. If your combined super is trending toward $3 million, model the impact of the new tax and whether it changes your contribution or investment strategy.
5. Coordinate with your estate plan. Ensure your binding death benefit nominations, reversionary pension elections, and will are all aligned with your super structure.
6. Review annually. Indexation changes, legislative amendments, and market movements all affect your position. This is not a set-and-forget exercise.

The Bottom Line

The $1.9 million transfer balance cap is not a barrier — it is a planning parameter. For high-balance members and couples, the strategies available to optimise your position are numerous and genuinely impactful. But they require precision. The interaction between personal transfer balance caps, contribution caps, tax components, Division 296, and estate planning creates a web of rules that rewards careful coordination.

If your super balance is in the seven-figure range, this is not territory to navigate alone. A well-structured plan can save you — and your family — hundreds of thousands of dollars over a lifetime.
