2026 Budget and ETFs: What Australian Investors Need to Know About CGT Changes
Most 2026 Federal Budget summaries focus on property, trusts or high-income investors.
But the proposed capital gains tax changes matter for everyday ETF investors too.
If you are buying broad-market ETFs in a taxable brokerage account, the Budget could change how future capital gains are taxed, how important low turnover becomes, and how you think about taxable investing versus super.
For the broader Budget picture, start with our hub article: 2026 Federal Budget: What Australian Investors Need to Know.
What is changing for CGT?
The Budget proposes replacing the 50% CGT discount with cost base indexation from 1 July 2027, plus a 30% minimum tax on capital gains.
Under the current system, an eligible investor who holds an asset for longer than 12 months may generally discount the capital gain by 50%.
Under the proposed system, the cost base would be adjusted for inflation, so tax is aimed at the real gain rather than the nominal gain. The 30% minimum tax is intended to prevent very low effective tax rates on gains.
The proposed rules have not yet been legislated, and the final details may change. Treat this as a planning framework, not personal tax advice.
How ETF investors may be affected
For long-term ETF holders, the big question is simple:
Will indexation be better or worse than the 50% CGT discount?
The answer depends on the relationship between inflation, investment returns and your tax rate.
If an ETF delivers strong returns well above inflation, the current 50% discount may be more favourable. If nominal returns are modest and inflation is high, indexation may produce a smaller taxable gain.
That is why broad rules of thumb can mislead. Use the actual numbers where you can. Our CGT discount vs indexation calculator lets you compare the current 50% discount, indexed cost base and proposed 30% minimum tax rule.
Why low-turnover ETFs may become even more attractive
Low-turnover ETFs already have a tax advantage: they tend to realise fewer capital gains inside the fund.
If the Budget changes pass, low turnover may become even more attractive because investors may want more control over when gains are realised. The less often a fund distributes realised capital gains, the more control the investor may have over the timing of their own CGT event.
That does not mean every low-turnover ETF is automatically better. Fees, index construction, diversification, tracking error and liquidity still matter. But tax drag becomes one more reason to prefer simple, broad, low-cost funds over strategies that churn holdings frequently.
Income, capital growth or total return?
The Budget may push some investors to revisit whether they prefer income-focused ETFs, growth-focused ETFs or a total-return approach.
Income-focused ETFs can be useful when you need cash flow, but distributions are generally taxable in the year you receive them. Capital-growth-focused ETFs may defer more of the tax until sale, which can be valuable for investors in accumulation mode.
The proposed CGT changes do not make income bad or capital growth good. They simply make the trade-off more explicit:
- income can improve cash flow but may create annual tax
- capital growth can defer tax but may face changed CGT treatment later
- total return keeps the focus on after-tax wealth, not just yield
For FIRE investors, the total-return lens is usually the cleanest starting point. The goal is not to maximise distributions or minimise tax in isolation. The goal is to build the most useful after-tax portfolio for your life.
What if you dollar-cost average across 1 July 2027?
Many ETF investors buy regularly: every pay cycle, every month or every quarter.
If you dollar-cost average across the transition date, different parcels may be treated differently.
Based on the Budget materials and NAB’s explanation:
- parcels bought and sold before 1 July 2027 would stay under current rules
- parcels bought after 1 July 2027 would fall wholly under the proposed new rules
- parcels bought before 1 July 2027 and sold after that date would have gains split between pre-transition and post-transition treatment
That makes parcel records more important. If you reinvest distributions, each reinvestment can create a new parcel with its own acquisition date and cost base.
Good ETF administration is boring, but this is where boring wins. Keep broker statements, distribution statements, AMMA tax statements and dividend reinvestment records.
Should ETF investors sell before 1 July 2027?
Not by default.
Selling before 1 July 2027 could realise gains under the current discount, but it may also bring tax forward and reduce the amount left invested. It can also create brokerage, spreads, time out of market and reinvestment risk.
For a long-term ETF investor, the value of deferring tax can be powerful. Even if future rules are less favourable, paying tax earlier is not automatically better.

Taxable brokerage account vs super
The Budget also highlights a bigger planning question: how much should you invest inside super versus outside super?
Taxable brokerage accounts offer flexibility. You can access the money before preservation age, use it for a career break, fund early retirement years or keep options open.
Super is usually more tax-efficient, but access is restricted. For many FIRE investors, the answer is not one or the other. It is a bridge:
- taxable investments can fund the years before super access
- super can fund later retirement
- the right split depends on age, income, savings rate, family plans and risk tolerance
The proposed CGT changes may make taxable investing slightly less attractive in some scenarios, but they do not remove the value of flexibility.
Practical checklist for ETF investors
If you hold ETFs in a taxable account, consider these steps:
- download your broker statements
- check cost base records for each parcel
- keep AMMA and distribution tax statements
- identify large unrealised gains
- review dividend reinvestment plan records
- model likely outcomes before selling
- avoid changing your asset allocation purely for tax reasons
If you are using leverage, margin loans or debt recycling, get personal advice. NAB notes that negative gearing appears to remain viable for shares, but that does not make leverage low-risk.
The bottom line
For ETF investors, the 2026 Budget is mostly about tax timing, record-keeping and after-tax return.
Low-cost, diversified, low-turnover ETFs still make sense for many long-term investors. The proposed CGT changes may change some of the maths, but they do not change the core idea: build a resilient portfolio, keep costs low, stay diversified and make tax-aware decisions without letting tax run the entire plan.
