Coverage of the proposed CGT changes has assumed personal investment as the default case. Self-managed super is treated as an afterthought, when it is mentioned at all. This is a gap. SMSF crypto holdings are growing, the existing tax treatment is different from personal holdings, and the proposed changes interact with super in ways that need to be worked through separately.

This article is for SMSF trustees holding crypto, or considering it, who want to understand what the proposal would change and what would stay the same.

How SMSF crypto is currently taxed

Three things to know about the existing framework.

First, complying super funds receive a one-third CGT discount on assets held for more than 12 months, not the 50% discount that applies to individuals. The maximum effective tax rate on long-term capital gains in accumulation phase is therefore 10%, which is two-thirds of the 15% super contributions tax rate.

Second, super funds in pension phase pay zero tax on capital gains from assets supporting a pension. This is the largest tax advantage in the Australian tax system. SMSFs holding crypto that transition into pension phase before a disposal currently pay nothing on the gain.

Third, SMSFs are subject to the same ATO crypto guidance as individuals. Every disposal is a CGT event. Staking, mining, and DeFi yields are ordinary income at receipt. The sole purpose test applies and limits how crypto can be used and stored within an SMSF.

What the proposal would change

The proposed changes apply to super funds, not just individuals. The mechanics work the same way.

• The one-third discount is removed.
• Inflation indexation of the cost base is applied instead.
• A minimum tax rate applies. For super funds, the rate floor has not been explicitly confirmed in the public proposal but the working assumption from tax practitioners is that the floor would be set at the existing super fund accumulation rate of 15%, not 30%.

Pension phase tax-free treatment is not affected by the CGT proposal in its current form. Assets supporting a pension would still pay zero on disposal. This is consistent with the proposal targeting concessions rather than the broader super framework.

Three scenarios for SMSF trustees

Scenario 1: SMSF in accumulation, holding crypto long-term

Current treatment: one-third discount, effective rate of 10% on long-term gains.

Proposed treatment: indexed cost base, taxed at 15% on the indexed gain (assuming no graduated floor change). For long-held positions, the indexing may offset a meaningful portion of the discount loss. A 5-year hold through 15% combined CPI growth indexes the cost base by 15%, which compares against the loss of the one-third discount.

Net effect: depends on inflation and holding period. Long-held, high-inflation environments produce outcomes closer to neutral. Short-held positions or low-inflation periods produce a meaningful tax increase.

Scenario 2: SMSF transitioning to pension phase soon

Current treatment: time the disposal after transition, pay zero.

Proposed treatment: time the disposal after transition, pay zero. The pension phase exemption is preserved.

Net effect: unchanged. This is the most valuable tax planning lever for SMSF crypto holdings and the proposal does not touch it.

Scenario 3: SMSF making new crypto acquisitions after the transition

Current treatment: one-third discount on long-term gains.

Proposed treatment: indexed cost base method only.

Net effect: the tax efficiency of new SMSF crypto investments compared to personal investments narrows under the proposal. Currently the SMSF saves significantly on long-term gains because of the lower super tax rate. Under the proposed rules, the gap remains but is smaller, because both personal and SMSF investors lose their respective discounts and gain inflation indexing.

The structural questions trustees need to think about

Three questions worth raising with an SMSF auditor or financial adviser.

• Pension phase timing. The proposal does not change the value of timing disposals to pension phase. If anything it increases the relative value of the pension phase exemption. Trustees with significant crypto gains and an upcoming retirement should be modelling this carefully.
• Acquisition timing within the SMSF. Holdings acquired before budget night 2026 retain access to the current treatment during the transition. SMSF trustees should know which holdings sit on either side of that cutoff.
• Record keeping at the trust level. SMSFs operate under stricter audit requirements than individuals. The indexed cost base methodology requires precise acquisition dates and AUD values, which most SMSF crypto records already capture but which will be tested more rigorously under the new framework.

Where SMSFs are advantaged under the proposal

Two structural advantages remain.

The pension phase exemption. Untouched by the proposal. Continues to be the most powerful tax planning mechanism for long-term SMSF crypto holdings.

The lower tax rate floor for super funds (assuming the 15% rate holds). Personal investors face a 30% floor under the proposal. SMSFs face their existing 15% rate. The relative advantage of holding crypto in super, compared to personally, is maintained.

Where SMSFs are disadvantaged

Two practical considerations push the other way.

The compliance burden. SMSF audits already scrutinise crypto holdings carefully. Indexed cost base methodology adds another layer of complexity. Auditors will need to verify CPI factors and indexed calculations alongside the existing transaction records.

Reduced flexibility. SMSF trustees cannot react to legislation as quickly as personal investors. The trust deed, investment strategy, and contribution caps all constrain timing decisions. If the proposal passes and pension phase becomes a critical timing variable, trustees with constrained flexibility will pay more.

The bottom line

The proposed CGT changes affect SMSF crypto holdings in ways that are similar in structure to personal holdings but different in magnitude. The lower super fund tax rate floor preserves SMSF efficiency relative to personal investment. The pension phase exemption is unchanged and remains the primary tax planning lever. The compliance burden grows under either tax framework but more under the proposed one.

SMSF trustees holding or considering crypto should be raising this with their auditor and adviser specifically. Generic personal-investor coverage of the proposal does not capture the SMSF interactions accurately.
