Minimum 30% CGT From 2027 Forces Rethink on Retiree Sales

A 30% minimum capital gains tax rate that takes effect from mid-2027 will force retirees to rethink two of the most popular retirement strategies: the gradual sell-down of shares and the sale of an investment property into superannuation, an analysis of the new regime shows.

Assets bought before that date are partly grandfathered. Gains accrued up to June 2027 still qualify for the 50% CGT discount. Any gain after that point carries a 30% floor on the effective tax rate, regardless of the owner's total income. That means a retiree who previously paid zero CGT on small share sales each year now faces a minimum 30% charge on every post-2027 gain.

The change hits the gradual share sell-down especially hard. Under the old rules, a retiree could sell shares in small parcels each year and pay little or no CGT because their personal tax rate was below the standard rate. The new minimum eliminates that advantage. Each sale now requires two CGT calculations: one for the pre-2027 portion with the discount, another for the indexed gain under the new regime. The analysis described that administrative complexity as a hidden cost.

Selling an investment property and contributing the proceeds to super was once a strategy that could produce a tax refund. The concessional contribution into super is taxed at 15%, and the sale's CGT could be offset by other deductions. Under the new system, the 30% minimum CGT cannot be reduced by deductions. The same transaction could generate a large tax bill, the analysis said. It noted that the catch-up rules still allow a one-off deductible super contribution of about $140,000 if previous concessional caps were unused, but that deduction now has less value against a non-reducible CGT.

The analysis pointed to one exception: deferring the gain until the owner qualifies for the age pension. At that point the 30% minimum disappears and CGT reverts to standard marginal rates, which are often zero for pensioners. The catch is that the asset must be held longer, and not everyone can wait.

For retirees holding shares with large built-in gains, the analysis suggested recycling into income-focused holdings or even high-yield savings accounts. Interest earned is taxed at personal rates, which can be much lower than 30%. The analysis described that as a counter-intuitive shift for a generation raised on investing in shares and property to reduce tax bills.

Every year that passes pushes more of the gain into the new regime. For assets bought after mid-2027, super tax deductions will be of much less benefit if the taxpayer does not have sufficient income from sources other than capital gains. The analysis advises reviewing investment strategies before July 1 next year, when the first post-2027 gains begin to accrue.
