In Australia’s dynamic investment environment, unrealised capital gains represent one of the most powerful – yet often overlooked – opportunities for building long-term wealth. These are the increases in the value of your assets – whether shares, property, managed funds, or other investments – that have not yet been “locked in” by selling. As of 2026, Australian tax rules continue to tax capital gains only when they are realised, meaning unrealised gains grow tax-free until you decide to sell. This deferral allows your investments to compound without annual tax drag, a significant advantage in a high-growth market like Sydney’s or the broader Australian share market.
With the new Division 296 rules applying to large superannuation balances from 1 July 2026 (now limited to realised earnings only), and ongoing discussions around potential capital gains tax reforms, understanding how to manage unrealised gains has never been more important. This guide outlines practical, ATO-compliant strategies to optimise your position, defer tax where possible, and maximise after-tax returns. As always, these strategies depend on your individual circumstances – professional advice is essential.

What Are Unrealised Capital Gains and Why Do They Matter in 2026?
An unrealised capital gains occur when an asset’s market value exceeds your cost base, but you have not yet sold or disposed of it. For example, if you bought shares for $50,000 that are now worth $80,000, you have a $30,000 unrealised gain. Under current rules, the Australian Taxation Office (ATO) does not tax this growth until a CGT event happens – typically a sale.
This tax-deferred growth is a cornerstone of successful investing. It lets your portfolio compound fully, potentially adding thousands (or hundreds of thousands) to your wealth over time. In 2026, with strong property and equity markets, many investors hold substantial unrealised gains. The key is managing when – and how – you eventually realise them to minimise the tax impact.
Understanding Unrealised Capital Gains Step by Step
Strategy 1: Hold Assets for the 12-Month CGT Discount
One of the simplest and most effective strategies remains qualifying for the 50% CGT discount. If you are an individual or trustee and hold an asset for more than 12 months before selling, only half of the capital gain is included in your assessable income and taxed at your marginal rate.
In practice, this means never selling just before the 12-month mark if you can wait a few extra weeks. For trusts, the same discount generally applies. Super funds receive a one-third discount. With potential changes to the discount under discussion ahead of the May 2026 federal budget, locking in the current 50% benefit where possible is prudent planning for Unrealised Capital Gains.
Strategy 2: Time Your Realisations Strategically
Tax on realised gains is added to your other income and taxed at your marginal rate. Selling in a year when your taxable income is lower – perhaps after retirement, during a career break, or following a deductible expense-heavy year – can significantly reduce the effective tax rate.
Consider market conditions too. If you need liquidity, look for opportunities to realise gains gradually rather than in one large transaction. Spreading realisations over multiple financial years can keep you in lower tax brackets and preserve access to the CGT discount on each parcel.
Strategy 3: Harvest Capital Losses to Offset Gains
Capital losses are a valuable tool. You can use current-year losses or carried-forward losses to offset realised capital gains dollar for dollar. Any excess losses can be carried forward indefinitely.
A common tactic is “loss harvesting” – deliberately selling underperforming assets at a loss to offset gains elsewhere in your portfolio. This is particularly useful in volatile markets. Just remember the ATO’s anti-avoidance rules: you cannot buy back the same or substantially identical asset within 30 days (the wash-sale rule does not apply in Australia in the same way as some other countries, but related-party rules and general anti-avoidance provisions still apply).
Strategy 4: Maximise Your Cost Base
Your cost base is not just the purchase price. It includes incidental costs such as stamp duty, legal fees, agent commissions, and capital improvements. Keeping meticulous records of every expense increases your cost base and reduces the taxable gain when you eventually sell.
For property investors, this can include renovation costs that improve the asset (as opposed to repairs, which are deductible separately). For shares, include brokerage and any non-deductible holding costs. A higher cost base directly lowers your unrealised gain exposure.
Strategy 5: Consider Ownership Structures and Income Splitting
The structure in which you hold investments can influence how Unrealised Capital Gains are eventually taxed:
- Discretionary trusts offer flexibility to distribute gains to lower-taxed family members.
- Companies pay a flat rate but lose the CGT discount.
- Superannuation provides concessional tax treatment, though balances above $3 million from 1 July 2026 may face additional tax on realised earnings under Division 296.
Reviewing your structures annually – especially with the new super rules now focused solely on realised earnings – can help align your portfolio with your overall tax and estate-planning goals.
Strategy 6: Leverage Superannuation in the 2026 Landscape
From 1 July 2026, Division 296 introduces higher taxes on realised earnings for individuals with total super balances above $3 million (with a new $10 million tier). Importantly, unrealised capital gains are excluded from the calculation.
This change removes earlier concerns about forced asset sales to cover tax on paper gains. Strategies now include:
- Contributing to super while balances are below thresholds.
- Considering the optional cost-base reset for Division 296 purposes (where available).
- Holding growth assets inside or outside super depending on your overall position.
For many investors, keeping unrealised gains growing inside super (subject to the 15% concessional rate until realisation) remains attractive.
Strategy 7: Maintain Impeccable Records and Plan for Transition
The ATO’s data-matching capabilities have increased, making accurate record-keeping non-negotiable. Use software or a professional to track acquisition dates, cost bases, and improvement expenses for every asset.
Regular portfolio reviews with a financial planner can help you model different realisation scenarios, stress-test against potential policy changes, and ensure your strategy remains aligned with your retirement, lifestyle, and legacy goals.
