Crypto in your SMSF: the honest maths

The pitch for holding crypto inside a self-managed super fund fits in one line: long-term capital gains taxed at an effective 10% instead of up to 23.5% personally. That line sells a lot of SMSF setups. The honest version needs a second line: the concession comes bundled with fixed costs and compliance rules that change the maths entirely depending on how much you're investing. So let's actually do the maths.

The headline rates, fairly stated

Personally, a top-bracket taxpayer selling crypto held over 12 months pays tax on half the gain at ~47% including Medicare — an effective ~23.5%. An SMSF in accumulation phase pays 15% on two-thirds of a long-term gain — an effective 10%. In retirement (pension) phase, assets supporting the pension can pay 0%. On a A$10,000 long-term gain: roughly A$2,350 personally versus A$1,000 in the fund — a A$1,350 saving. Real, but notice: it's proportional to gains, while the costs below are fixed.

The line every spreadsheet must cross

An SMSF costs real money to exist: administration, the mandatory annual audit, ASIC and levy fees — commonly A$2,000–$4,000 a year even for simple funds, before any advice. Against the A$10k-gain column, the concession doesn't even cover one year's running costs. Against the A$200k column, it covers years of them. That's the whole shape of the decision: SMSF crypto is a scale game. The commonly-cited viability threshold for SMSFs generally — a few hundred thousand in fund assets — applies with extra force when the strategy involves an asset the auditor will examine closely.

The constraints the brochure skips

You generally can't move your existing crypto in — related-party acquisition rules block it; the path is selling personally (a CGT event at your personal rate) and contributing cash within caps. The concessional rate only helps if the fund keeps the asset long enough to matter — super is locked until preservation age, so this is a decades bet on an asset class barely one decade into institutional life. And every rule on our SMSF hub — separation of assets, sole purpose, June-30 valuations — carries audit scrutiny and, for breaches, penalties that can dwarf any tax saved.

Who the maths actually favours

The profile where SMSF crypto stacks up: an established fund already paying its fixed costs for other reasons, trustees comfortable with compliance, an allocation sized as a slice of a diversified fund (not a conviction bet), platforms with real SMSF onboarding (we list them), and — for many funds — the simpler exposure of ASX crypto ETFs, which auditors process without a second look. The profile where it doesn't: setting up a fund from scratch primarily to get 10% on a five-figure crypto punt. The concession is real; it just isn't free, and below a certain scale it isn't even cheap.
