In short

Total Superannuation Balance (TSB), measured once at 30 June each year, gates several super contribution entitlements for the following financial year: non-concessional contributions and bring-forward tiers (nil once TSB reaches $2.1 million for 2026-27), carry-forward concessional contributions (lost once TSB reaches $500,000), the government co-contribution, and the spouse contribution tax offset.

For anyone who wants to make voluntary super contributions in the year ahead, one number decides almost all of it: Total Superannuation Balance (TSB), measured once a year at the close of 30 June. TSB is not the same as your account balance and it is not the same as the Transfer Balance Cap. It is a specific legal concept — the sum of all your superannuation interests across every fund and phase — and it functions as the gatekeeper for a range of contribution entitlements. Understanding where your TSB sits relative to the key thresholds is one of the most practical super planning tasks a pre-retiree or retiree can undertake.

TSB includes every super interest a member holds: accumulation-phase balances in any fund, the value of any retirement-phase income streams (account-based pensions, term-allocated pensions), the value of any defined benefit interests (calculated using a specific formula rather than simply the pension amount), and any amounts in transit between funds at 30 June. For most members with straightforward structures, TSB is simply accumulation plus retirement-phase pension. For members with defined benefit interests, the calculation is different and the resulting TSB can be materially different from an intuitive estimate — worth checking in myGov rather than guessing.

The most consequential gate TSB controls is eligibility to make non-concessional contributions (NCCs) and to use the bring-forward provisions that allow up to three years' worth of caps in a single year. The annual NCC cap for 2026-27 is $130,000 per person. The bring-forward tier available depends on TSB at 30 June of the prior year. For 2026-27, members with a TSB below $1.84 million at 30 June 2026 can access the full three-year bring-forward of $390,000. Members with a TSB between $1.84 million and $1.97 million are limited to a two-year bring-forward of $260,000. Members with a TSB between $1.97 million and $2.1 million can contribute only the single-year cap of $130,000. Members with a TSB at or above $2.1 million cannot make non-concessional contributions at all. The $2.1 million ceiling aligns with the 2026-27 general Transfer Balance Cap, which rose from $2.0 million in 2025-26. Members who were just below the nil-contribution threshold in 2025-26 should check their TSB again in 2026-27: the ceiling has moved up.

A second gate — more relevant to members in their forties and fifties but often overlooked by pre-retirees — is the carry-forward concessional contribution. Concessional contributions are the before-tax amounts flowing into super: employer super guarantee, salary sacrifice, and personal deductible contributions. The annual concessional cap for 2026-27 is $32,500. Members who have not used their full concessional cap in prior years can carry forward unused amounts and contribute above the annual cap in a later year — but only if TSB was below $500,000 at 30 June of the year before. Above that threshold, unused carry-forward capacity is not available. This is a significant distinction: the window for catch-up concessional contributions closes permanently once TSB crosses $500,000, and members who are not aware of this can miss a meaningful opportunity to build their balance at concessional tax rates.

Two further entitlements are gated partly by TSB. Government super co-contribution — where the government matches after-tax contributions made by low-to-middle-income earners — requires the member's TSB to be below the general Transfer Balance Cap ($2.1 million for 2026-27) at 30 June 2026. The spouse contribution tax offset, which allows a tax offset of up to $540 for contributing to a spouse's super, similarly requires the receiving spouse's TSB to be below $2.1 million.

SMSF event-based reporting (TBAR) is now uniformly quarterly for all SMSFs since 1 July 2023 — the previous tiered system based on member TSB thresholds was simplified to a single quarterly cycle. SMSF trustees must report Transfer Balance Account events within 28 days of the end of the quarter in which the event occurs (ATO TBAR guidance).

TSB and the Transfer Balance Cap (TBC) are frequently confused and worth distinguishing clearly. TSB is the sum of all super interests across all phases, measured at 30 June, and controls contribution capacity. TBC is the lifetime limit on how much can be placed into retirement phase — where investment earnings are completely tax-free — and controls the tax-free retirement-phase concession. A member with $2.5 million in super is not in breach of the TBC provided the $2.1 million TBC maximum is in retirement phase and the remaining $400,000 is in accumulation. But that member has a TSB above $2.1 million and cannot make further non-concessional contributions. The two concepts intersect at the top end because the nil-NCC threshold is set equal to the general TBC, but they measure different things and sit alongside each other in a compliant structure.

The 30 June snapshot timing matters in practice. TSB is measured once: at the close of 30 June each year. The figure on that date sets contribution eligibility for the following financial year. A member who is above a threshold on 30 June cannot retroactively change their position for the year that follows. For members close to a threshold — particularly the $500,000 carry-forward line or any of the NCC bring-forward tiers — the weeks before 30 June are the planning window. A market-driven balance movement, the timing of a pension payment, or the decision whether to make a final contribution before year-end can all shift TSB across a threshold in either direction.

TSB is calculated per member, not per couple. Each spouse has their own TSB, independent of the other. This produces a material planning lever for couples where the balances are asymmetric. Where one partner's TSB is significantly higher than the other's, the lower-balance partner may retain access to NCC bring-forward, carry-forward concessional capacity, and other entitlements the higher-balance partner has lost. Combined household contribution capacity is maximised when balances are equalised over time rather than concentrated in one partner. Equalisation can be approached through spousal non-concessional contributions (after-tax contributions made directly to the lower-balance spouse's fund), concessional contribution splitting (transferring up to 85 per cent of one partner's annual concessional contributions to the other in the following financial year), or recontribution strategies at retirement. For couples with a multi-year gap between balances, equalisation is a deliberate multi-year project rather than a single decision.

Members approaching the key TSB thresholds — $500,000 for carry-forward concessional access, $1.84 million for full three-year NCC bring-forward eligibility, $1.97 million for two-year bring-forward, and $2.1 million for any NCC eligibility at all — should check their current TSB in myGov under ATO services before the financial year closes. For couples, reviewing both TSBs and the gap between them is worth adding to the annual pre-June checklist.

Key takeaways

  • TSB is measured once, at the close of 30 June each year, and sets your contribution eligibility for the following financial year — it can't be changed retroactively.
  • Non-concessional contribution bring-forward eligibility depends on TSB tiers: full 3-year bring-forward ($390,000) below $1.84 million, 2-year ($260,000) between $1.84m-$1.97m, single-year ($130,000) between $1.97m-$2.1m, and nil at or above $2.1 million (FY2026-27).
  • Carry-forward concessional contributions are lost permanently once TSB crosses $500,000 at the prior 30 June — a fixed, unindexed threshold, unlike the NCC tiers which move with the Transfer Balance Cap.
  • Government co-contribution and the spouse contribution tax offset both require TSB to be below the general Transfer Balance Cap ($2.1 million for 2026-27).
  • TSB is calculated per individual, not per couple — asymmetric balances between spouses create a planning lever, since the lower-balance partner often retains contribution entitlements the higher-balance partner has lost.

Frequently asked questions

What is Total Superannuation Balance and how is it different from my account balance?

TSB is the sum of all your superannuation interests across every fund and phase — accumulation balances, retirement-phase pension values, and defined benefit interests — measured once at 30 June each year. It's a distinct legal concept from both your individual account balance and the Transfer Balance Cap.

What TSB do I need to be under to make non-concessional contributions?

For FY2026-27, TSB below $1.84 million gets the full three-year bring-forward ($390,000), between $1.84m and $1.97m gets a two-year bring-forward ($260,000), between $1.97m and $2.1m gets only the single-year cap ($130,000), and at or above $2.1 million you can't make non-concessional contributions at all.

What TSB do I need for carry-forward concessional contributions?

Your TSB must have been below $500,000 at the prior 30 June. This threshold is fixed by legislation and doesn't move with indexation the way the non-concessional contribution tiers do — once TSB crosses $500,000, catch-up concessional contribution access is lost permanently.

Does my spouse's super balance affect my own contribution entitlements?

No — TSB is calculated per individual, not per couple, so each spouse's entitlements depend only on their own balance. This means a lower-balance partner can often still access bring-forward or carry-forward contributions even after the higher-balance partner has lost that access, which is a genuine planning lever for couples.
