2026-27 resident rates used for extra tax

A net capital gain is taxed as ordinary taxable income. These bands come from the ATO resident rates page and exclude the Medicare levy. They are the same tables as the 2026-27 income tax calculator.

$18,201 – $45,00015c for each $1 over $18,200

How the 2026-27 CGT figure is built

Sale price minus cost base is the raw result. Losses are subtracted next. A resident sale after the 12-month test then keeps only half of what remains. That net gain is stacked on your other 2026-27 taxable income so the extra tax reflects the 15% second band and the 30%, 37% and 45% bands above it.

Frequently Asked Questions

How is extra CGT tax worked out in 2026-27?

The net capital gain is added to your other taxable income. Extra tax is the rise in 2026-27 resident income tax — and the Medicare levy if you leave that box ticked — compared with the same income without the gain. The second resident band is 15% from 1 July 2026.

Does the 50% discount change in 2026-27?

No. Resident individuals still reduce an eligible gain by half after losses. What changes year to year is the income-tax table applied to the amount that remains.

Which sale date belongs on the 2026-27 return?

The CGT event date. For a property sold under contract that is usually the contract date, not settlement. Events from 1 July 2026 to 30 June 2027 belong in 2026-27. This page still lets you type an earlier sale if you only want to compare extra tax at 2026-27 rates.

Are 2026-27 Medicare levy thresholds published?

The 2% levy rate is published. As of 2026-11-01 the ATO reduction page still lists the 2025-26 singles shade-in amounts. Extra Medicare on this page uses those latest published figures and says so on screen.
