Water entitlements and the 2027 CGT changes: what's changing and where you stand
From 1 July 2027, the way capital gains are taxed in Australia changes: for individuals, trusts and partnerships, the 50% CGT discount is replaced by inflation indexation of the cost base, with a minimum 30% rate on the real gain. For anyone holding a water entitlement bought years — often decades — ago, it's worth understanding your position early. Here's what's changing and where to start.

What changes on 1 July 2027
The 50% discount
For assets held at least 12 months, individuals (and, through trusts and partnerships, their beneficiaries and partners) are taxed on only half the capital gain. A water entitlement held since the 2000s with a large accrued gain gets the full benefit of that discount on sale.
Indexation + 30% minimum
The flat discount is replaced by cost-base indexation (again with a 12-month holding condition): your cost base is adjusted upward for inflation, and tax applies only to the real gain — but at a minimum 30% rate, with an exemption from the minimum for recipients of means-tested income support such as the Age Pension. For assets whose value has grown far faster than inflation, more of the gain is taxable.
Crucially, the legislated transitional rules mean this is not a sell-by deadline. Assets already held at 30 June 2027 are treated as notionally disposed of and reacquired on that date: the gain accrued up to 1 July 2027 keeps the 50% discount when you eventually sell, generally measured by the asset's market value at 1 July 2027 (an elective apportionment method is the alternative). What changes is the treatment of growth after that date. The practical consequence for entitlement holders is not “sell before the deadline” — it's “be able to prove what your entitlement was worth at 1 July 2027.”
Why water entitlements are squarely in the frame
Water entitlements have appreciated substantially over the past two decades. Many northern Victorian water shares were acquired when water was unbundled from land in 2007 — or earlier — at a fraction of today's values. In the 2025-26 season, high-reliability shares in the Murray below the Choke (Zone 6B/7) have transferred at a volume-weighted average of around $7,950/ML.
Take a worked example: a 100 ML high-reliability water share in Zone 6B/7 is indicatively worth about $795,000 at current published values. If you already hold it at 30 June 2027, the transitional rules preserve the 50% discount on the gain accrued up to that date — measured against the entitlement's market value at 1 July 2027. What falls under the new indexation and minimum-rate rules is the growth after that date. So the question for existing holders isn't “do I have to sell before July 2027” — it's “what will my entitlement be worth on 1 July 2027, and can I prove it later?”
Three groups have particular reason to pay attention. Holders of pre-1985 entitlements, whose historic blanket CGT exemption is curtailed — growth after 1 July 2027 becomes taxable for the first time. Anyone planning to buy or sell in the next few years, because timing now interacts with the new rules. And farming businesses, for whom the small business CGT concessions — which survive the reform unchanged — are often worth more than the discount ever was.
Selling allocation is a different story
This page is about permanent entitlements (water shares). Selling seasonal allocation is generally treated as ordinary income for irrigators — revenue, not a capital gain — so the CGT discount never applied and the 2027 changes are largely beside the point. If you're not sure which you hold, here's the difference explained.
Why it's worth knowing your position now
There is no contract-date cliff for existing holders — the transitional rules see to that. But the new regime turns on a number most entitlement holders have never had to establish: what their water shares are worth at a specific date. Contemporaneous evidence of value around 1 July 2027 — and a record of what you paid and when — will make your accountant's job far easier when you do eventually sell.
And if selling is part of your thinking anyway, a permanent entitlement sale is not an overnight transaction: finding the right buyer, contract, registry transfer and settlement typically takes weeks, and the entitlement market is thinner than the allocation market. Whatever the tax position, you want to be selling into a strong market — not against a calendar.
Current market value of your entitlement, by zone and reliability — and keep a dated record.
Cost base, structure, concessions, transitional rules — the tax side is theirs.

Common questions
Is selling a water entitlement a CGT event?
Generally yes. A water entitlement (water share) is a CGT asset, and selling or transferring it is usually a CGT event — you may make a capital gain or loss based on the sale proceeds versus your cost base. Some specific rollovers exist (for example where an entitlement is reduced or replaced by a government program), and the treatment depends on how and by whom the entitlement is held. Confirm your position with a registered tax agent.
Do the 2027 CGT changes apply to water allocation sales?
For most irrigators, no. Selling seasonal allocation is generally treated as ordinary income (revenue account), not a capital gain, so the CGT discount was never part of the picture. If you hold water as a passive investment rather than in a farming business, the treatment can differ. The 1 July 2027 changes are primarily relevant to permanent entitlements (water shares), which are capital assets. Your accountant can confirm how allocation sales are treated in your circumstances.
What actually changes on 1 July 2027?
Under the legislated reforms, the 50% CGT discount for individuals, trusts and partnerships is replaced by cost-base indexation — your cost base is adjusted upward for inflation (CPI) over the holding period, and tax applies only to the real gain. A minimum 30% rate applies to that real gain, with an exemption from the minimum for recipients of means-tested income support such as the Age Pension. Companies were never eligible for the discount, and complying super funds (including SMSFs) are outside the change entirely — their one-third discount continues.
What happens to gains I have already accrued before 1 July 2027?
The legislated transitional rules preserve them. Assets held at 30 June 2027 are treated as notionally disposed of and reacquired on that date: the gain accrued up to 1 July 2027 keeps the 50% discount when you eventually sell, generally measured by the asset’s market value at 1 July 2027, with an elective apportionment method as the alternative. That makes contemporaneous evidence of your entitlement’s value around 1 July 2027 genuinely important — it is the number your future tax calculation turns on.
Do the small business CGT concessions still apply?
Yes. The Division 152 small business CGT concessions — including the 15-year exemption and the retirement exemption — were unchanged by the 2027 reform, and for entitlements used in a farming business they can reduce or even eliminate a gain entirely. For many family farms they are worth more than the discount ever was, so do not assume the 2027 changes drive your decision before your accountant has looked at the concessions.
What is the cost base of an inherited water entitlement?
It depends on when and how the deceased acquired the entitlement. Broadly, if the deceased acquired it after 19 September 1985, you generally inherit their cost base; if they acquired it before that date, your cost base is usually the market value at the date of death. Inherited water shares are common in family farming succession, and the records are often incomplete — start the conversation with your accountant early.
Are water entitlements bought before September 1985 exempt from CGT?
Historically, yes — assets acquired before 20 September 1985 have been fully exempt as pre-CGT assets, and CGT rollover provisions generally preserved that status through Victoria’s 2007 unbundling. But the 2027 reform curtails the exemption: gains accrued up to 1 July 2027 generally remain exempt, while growth after that date becomes taxable, measured against the entitlement’s market value at 1 July 2027. Pre-1985 holders are among those most affected by the change, and establishing your entitlement’s 1 July 2027 value will matter. Confirm your position with a registered tax agent.
Should I sell my water entitlement before 1 July 2027?
The transitional rules mean there is no discount cliff for entitlements you already hold — the gain accrued to 1 July 2027 keeps the 50% discount whenever you sell. So this is a decision for you and your accountant on its own merits: your cost base, holding structure, any small business concessions, income position, and what you would do with the proceeds, weighed against the water market itself. What we can tell you is the market side: what your entitlement is realistically worth today and how the market is moving. Start with a current valuation, take it to your accountant, and make the call with both numbers on the table.
