Exempt current pension income, disregarded small fund assets, and why the day you draw down your pension matters more than you think.
Many trustees of self managed superannuation funds (SMSFs) assume that once a member moves into retirement phase, the income and capital gains attributable to their pension are simply tax‑free. It is a reasonable assumption and, in the right circumstances, broadly correct. But the mechanics of the exemption are far more subtle than most trustees realise and a single poorly‑timed transaction can turn what looks like a tax‑free capital gain into a substantial tax bill.
This article explains how the exempt current pension income (ECPI) rules actually work, the critical difference between the segregated and proportionate methods, the little‑understood “disregarded small fund assets” rules that force many funds down the more expensive path, and through a worked example why withdrawing a large pension balance early in the financial year can dramatically increase a fund’s tax.
What is exempt current pension income?
When an SMSF pays a retirement phase superannuation income stream (a pension), the income earned on the assets supporting that pension is generally exempt from the fund’s 15% income tax. This exemption is called exempt current pension income and it is found in Subdivision 295‑F of the Income Tax Assessment Act 1997 (Cth) (ITAA 1997).
Critically, ECPI extends beyond ordinary income such as rent, dividends and interest. It also covers net capital gains – so a fund that sells a long‑held property or share parcel while supporting a pension may be able to treat some or all of that gain as exempt.
The obvious question is: how much of the fund’s income is exempt? That depends entirely on which of two methods applies.
The two methods: segregated versus proportionate
The law provides two mechanisms for calculating ECPI, and they produce very different outcomes.
The segregated method (section 295‑385)
Under the segregated method, the fund sets aside specific assets to solely support its retirement phase pension liabilities. Those assets become “segregated current pension assets”, and all of the income and capital gains they generate are exempt, regardless of the size of any other accumulation interests in the fund.
Where a fund is entirely in retirement phase – that is, every member’s interest is a pension and there are no accumulation accounts – the fund is treated as holding all of its assets to support pensions. In that case all of its income is exempt, and (for account‑based pensions) no actuarial certificate is even required.
The segregated method is powerful precisely because it looks at which assets earned the income, not at averages. If the asset that produced a large capital gain was a segregated pension asset at the time of the gain, the whole gain is exempt.
The proportionate method (section 295‑390)
Under the proportionate method – also called the unsegregated method – the fund does not set aside particular assets. Instead, all assets are pooled, and an actuary certifies the proportion of the fund’s income that is exempt using the formula in section 295‑390 of the ITAA 1997:
Average value of current pension liabilities ÷ Average value of superannuation liabilities
That single percentage – the actuarial exempt income proportion – is then applied to all of the fund’s assessable income for the relevant period, including any net capital gain, regardless of which member’s interest the income relates to and regardless of when in the year a particular gain was realised.
This is the crucial distinction. The segregated method asks “was this asset a pension asset when it earned income?” The proportionate method asks “what proportion of the whole fund, on average across the year, was supporting pensions?” and applies that average to everything.
The trap: disregarded small fund assets (section 295‑387)
Here is where many trustees come unstuck. You might assume that a fund can simply choose the segregated method when it is more favourable. For a large number of SMSFs, that choice has been taken away.
Since 1 July 2017, section 295‑387 of the ITAA 1997 provides that a fund has disregarded small fund assets in an income year if all of the following are true:
- at least one member of the fund is, at any time during the year, receiving a retirement phase income stream from the fund;
- just before the start of the income year, a member of the fund had a total superannuation balance exceeding $1.6 million; and
- that member was, just before the start of the year, the retirement phase recipient of a superannuation income stream from any source, not just this fund.
Where a fund has disregarded small fund assets, it is prohibited from using the segregated method and must use the proportionate method for the whole of the income year.
The policy rationale is to stop wealthy members from cherry‑picking segregation to shelter specific high‑gain assets. But the practical consequence is severe: a fund that would have enjoyed a full exemption on a specific asset under segregation is instead forced onto a single blended average and, as we will see, that average can be pushed down to almost nothing by the timing of a large withdrawal.
The one carve‑out: a fund wholly in pension phase all year (section 295‑387(3))
There is an important exception. Section 295‑387(3) provides that a fund is not caught by the disregarded small fund assets rules if, at all times during the income year, all of the fund’s assets would be segregated current pension assets.
In plain terms, if the fund is 100% in retirement phase for every day of the year, every member’s interest is a pension, there are no accumulation interests, and all assets support those pensions, then the fund escapes the proportionate‑method lock‑in, even where a member’s total superannuation balance exceeds $1.6 million. Such a fund can be treated as fully segregated and all of its income (including capital gains) is exempt.
How the proportion is actually calculated – daily weighted average
A common misconception is that the actuary works out the exempt proportion using the pension balance at the start of the year, or at the end of the year. It does neither.
The average values in the section 295‑390 formula are determined using a daily weighted average across the entire income year. The calculation begins with the opening balances of each member’s pension and accumulation accounts and then layers in the size and timing of every material transaction during the year – pension commencements, commutations, contributions, pension payments, lump‑sum withdrawals and transfers.
Two principles follow from this:
- Every day counts. A balance that sits in retirement phase for 300 days contributes far more to the average than the same balance sitting there for 30 days.
- Timing carries weight. A large transaction early in the year affects the average for the many remaining days of the year; the same transaction late in the year barely moves the average at all.
This daily‑weighting is entirely logical but it produces outcomes that surprise trustees who think in terms of a single snapshot balance.
Worked example: the cost of an early withdrawal
Consider an SMSF with two members. Assume the following (figures rounded for illustration):
- At 1 July, the fund’s total assets are $3,500,000.
- On 1 July, Member A commences an account‑based pension of $1,760,000 (having just turned 65). Member B remains entirely in accumulation.
- Early in the income year the SMSF sells a long‑held property, producing a net capital gain (after the one‑third SMSF CGT discount) of approximately $1,200,000.
- On 31 July on settlement of the sale of a major asset of the SMSF supporting the pension, Member A withdraws $1,750,000 of the pension as a lump sum, leaving only about $10,000 in the pension account.
What the trustee expected
The trustee looks at the position on 1 July and reasons: “Half the fund – $1,760,000 out of $3,500,000, or roughly 50% – was in pension phase, so about half of my gain should be tax‑free.”
On that (incorrect) opening‑balance logic:
| Amount | |
| Net capital gain | $1,200,000 |
| Exempt at ~50.3% | $603,000 |
| Taxable | ~$597,000 |
| Tax at 15% | ~$89,500 |
What the law actually produces
Because the $1,750,000 was withdrawn on 31 July, the large pension balance was only in the fund for about 30 of the 365 days. The daily weighted average pension balance across the year is therefore tiny relative to the fund:
- Average value of pension liabilities (daily weighted): ≈ $153,800
- Average value of total fund liabilities (daily weighted, allowing for the $1.75m leaving the fund): ≈ $1,893,800
- Exempt proportion = $153,800 ÷ $1,893,800 = ≈ 8.1%
Applying the correct proportion:
| Amount | |
| Net capital gain | $1,200,000 |
| Exempt at ~8.1% | ~$97,500 |
| Taxable | ~$1,102,500 |
| Tax at 15% | ~$165,400 |
The difference
The trustee expected tax of around $89,500. The correct figure is around $165,400 – a difference of roughly $75,900 on this single gain, driven entirely by the timing of one withdrawal.
Why the early withdrawal is so costly
The damage flows from the interaction of three rules:
- The disregarded small fund assets rule (s 295‑387) removed the option to segregate. Had segregation been available, the fund might have sheltered the specific asset that produced the gain – or claimed a full exemption for any period it was wholly in pension phase.
- The proportionate method (s 295‑390) uses a whole‑of‑year daily average. It does not matter that the property may have been sold on, say, 25 July – while the pension balance was still high. Under the proportionate method the exempt proportion is a single figure applied to all income for the period; it is not matched to the date a particular gain was realised.
- The early withdrawal collapsed the average. By taking $1.75m out on 31 July, the member left the fund with almost nothing in retirement phase for eleven of the twelve months, dragging the average – and therefore the exemption – down to a fraction of what the trustee assumed.
Had the same member instead retained the pension balance in the fund for most of the year and drawn it down late, the daily weighted average – and the exemption – would have been dramatically higher.
Practical lessons for trustees and advisers
- Do not assume “pension phase equals tax‑free.” The exemption is proportional and time‑weighted, not a simple on/off switch.
- Check for disregarded small fund assets before planning. If a member had more than $1.6 million in total superannuation and was already drawing a pension, the fund may be locked into the proportionate method and cannot segregate to protect a specific gain.
- Consider the calendar on large withdrawals and commutations. The timing of a significant lump sum can move the actuarial percentage by tens of percentage points. Where a large realised gain is expected, model the ECPI outcome before moving pension money.
- Consider the sequencing of asset sales and pension drawdowns together. Selling an asset and withdrawing a pension in the same year can produce counter‑intuitive results under the proportionate method.
- Reconcile the actuarial certificate. The certified percentage should be tested against the fund’s records; an unexpectedly low percentage is often explained – as here – by the timing of a withdrawal rather than by any error.
How Vale Legal can help
The ECPI rules sit at the intersection of superannuation law, the capital gains tax provisions and careful transaction timing – and small differences in sequencing can produce very large differences in tax. At Vale Legal we advise trustees, accountants and other advisers on SMSF taxation, the exempt current pension income rules, the disregarded small fund assets provisions and the CGT consequences of asset disposals within superannuation. Where a calculation looks wrong, we review the fund’s returns, actuarial certificates and workpapers to confirm the correct position and, where appropriate, advise on amendment.
