There is a precise moment in the life of a self-managed super fund when the tax treatment of its Earnings flips. On one side sits the accumulation phase, where Investment earnings are taxed at 15 per cent. On the other sits the retirement phase, where earnings on the Assets supporting a pension become Exempt Current Pension Income and are taxed at 0 per cent. The mechanism connecting the two is what accountants and actuaries call the ECPI claim — the technical process by which an SMSF works out exactly how much of its income is exempt. Getting that calculation right is where the real work of a “tax switch” happens, and it is more involved than simply flicking a lever.

 

The switch from accumulation to retirement phase

Accumulation is the default phase for Superannuation savings. Contributions and earnings build up, taxed at concessional rates, until a member is able to convert some or all of their balance into a retirement income stream. When a member meets a condition of release and the trustees commence a retirement-phase pension — most commonly an account-based pension — the assets supporting that pension move into the retirement phase.

From that point, the fund is no longer taxed at 15 per cent on the earnings attributable to those assets. Instead, those earnings become Exempt Current Pension Income (ECPI), meaning the fund does not pay tax on the income and capital gains they produce. The switch is real, but it applies only to the portion of the fund supporting retirement-phase pensions — not automatically to the whole fund.

 

What Exempt Current Pension Income actually is

ECPI is the mechanism the tax law uses to deliver the retirement-phase exemption. Rather than treating a fund as wholly taxable or wholly exempt, the rules require an SMSF to identify the income earned on assets that are supporting retirement-phase income streams and exclude that income from the fund’s assessable income for the year. For a fund that is entirely in retirement phase, effectively all ordinary income is exempt; for a fund with both accumulation and pension interests, only part is.

There are two methods a fund can use to claim ECPI, and the choice — or the requirement — depends on how the fund’s assets are structured.

 

Method one: the segregated approach

Under the segregated method, specific assets are set aside and identified as solely supporting retirement-phase income streams. Because those assets are clearly earmarked, all of the income they generate is exempt, and the fund claims ECPI directly on that income without needing to apportion.

The segregated method can be attractive for funds that are entirely in retirement phase for the full year, where every asset supports a pension. It is more complex where a fund moves between phases or holds a mix of accumulation and pension interests, and there are specific rules that prevent certain funds from using asset segregation for ECPI purposes in particular circumstances. Segregation for tax purposes is also distinct from the ordinary commercial idea of keeping investments separate.

 

Method two: the proportionate approach

Under the proportionate (also called unsegregated) method, the fund’s assets are pooled rather than earmarked. An actuary calculates the proportion of the fund’s income that is exempt, based on the average value of the fund’s retirement-phase liabilities relative to its total liabilities across the year. That percentage — the exempt proportion — is then applied to the fund’s income to determine the ECPI amount.

This method suits funds that hold a single pool of assets supporting both accumulation and pension interests, which is common in practice. It smooths the exemption across the whole pool rather than tying it to specific holdings.

 

When an actuarial certificate is required

The proportionate method depends on an actuarial certificate. Where a fund uses the proportionate method to claim ECPI, it generally must obtain a certificate from an actuary each year confirming the exempt proportion. Without the certificate, the fund cannot claim ECPI under that method.

By contrast, a fund that uses only the segregated method for assets that are solely supporting retirement-phase pensions for the full year generally does not need an actuarial certificate for that income. The interaction between the two methods can be intricate, particularly for funds that are fully in retirement phase for only part of the year, and this is an area where SMSF trustees frequently rely on their accountant, administrator or actuary.

 

A hypothetical illustration

For illustration only: the Nguyen Family SMSF has two members. One member’s balance of $800,000 supports an account-based pension in the retirement phase, while the other member’s $400,000 remains in accumulation. The fund holds all its investments in one pool. Because assets are not segregated, the trustees use the proportionate method and obtain an actuarial certificate showing, say, that roughly two-thirds of the fund’s income is exempt. That exempt proportion is applied to the fund’s earnings to calculate ECPI; the balance of the income remains taxable at 15 per cent. The figures here are hypothetical and used only to show how the mechanics work.

 

What SMSF trustees need to know

The tax switch is powerful, but it is a compliance exercise as much as a tax benefit. Trustees need to know which method applies to their fund, whether an actuarial certificate is required, and that the exemption attaches to assets supporting a genuine retirement-phase pension. Minimum pension payments must still be met, because a pension that fails the minimum can be treated as not being in retirement phase, unwinding the ECPI claim for the year. Accurate valuations and records underpin the whole calculation.

 

Key Takeaway

Entering the retirement phase switches an SMSF’s earnings from 15 per cent tax to 0 per cent through Exempt Current Pension Income. ECPI can be claimed using the segregated method, where specific assets are earmarked to a pension, or the proportionate method, where a pooled fund relies on an actuarial certificate to determine the exempt proportion. Which method applies, and whether a certificate is needed, depends on the fund’s structure.
