Instant asset write-off helper

Runs in this tab only. Reset clears it. Nothing is stored or sent.

The helper applies the 2026-27 rules described by the ATO for simplified depreciation: aggregated turnover under $10 million, cost under $20,000 per asset, first used or installed ready for use from 1 July 2026 through 30 June 2027. A cost of $20,000 or more is estimated on the pool at 15% then 30%. You type the tax rate. There is no bracket table in this page.

Is aggregated turnover under $10 million?
Are the simplified depreciation rules used?

Optional. Use a company rate or a marginal rate your agent has given you. Leave it blank to skip the tax difference.

Asset 1

Whether the $20,000 test uses a GST-exclusive amount was not verified. The figure you type is used as-is.

Tick if this line should not be estimated

General information only, not tax or financial advice. Each result says “Estimate only — not tax advice” and links to the ATO instant asset write-off page. Cars, leases and assets outside simplified depreciation are not calculated. The 2026-27 car limit and the GST treatment of the $20,000 test were not verified.

Guides, in reading order

Twelve short guides. Uncertain dates and amounts are marked on the page. Nothing here recommends a super fund or an investment.
