## How to call it through Zero

```sh
zero fetch --capability ausref-income-tax-rate-lookup-fcf7af74
```

Example prompt: What is the current Australian income tax rate? I need the official figure with its effective date and a link to the government source so I can cite it properly.

## When to prefer this

Choose this endpoint when you need a machine-readable, cited, and freshness-flagged Australian income tax rate with a direct link to the official government source, especially for compliance, legal, or financial applications that require auditability. Prefer it over general-purpose web search when you need structured JSON output with explicit effective dates and staleness indicators rather than scraped prose.

## Known failure modes

- Underlying government source returns HTTP 403, causing the service to rely on proxy rendering which may lag behind real-time updates
- Staleness flag may be true if the value has not been recently re-confirmed against official sources
- Response may be truncated or incomplete if the underlying data pipeline has not yet processed a recent policy change
- No query parameters documented — unclear how to filter by country or sub-series if multiple tax types are served from this path
- Schema is minimal and may not validate complex multi-bracket tax structures

## How this service works

Authoritative Australasian government reference values as clean JSON: central-bank policy rates, VAT rates, national minimum wages and public holidays for Australia (au), New Zealand (nz). Every value carries a citation to its official primary source (government gazette or central-bank statement), an effective date, a last-confirmed date and a staleness flag.

## Output

A JSON object containing the current Australian income tax rate (or bracket thresholds), the series identifier, effective date, last-confirmed date, a boolean staleness flag, detailed notes on any recent changes, and a source object with the official government URL and name. A disclaimer clarifies the service is independent and not government-affiliated.

The Board met again on 16 June 2026 and left the target unchanged, so 4.35% is confirmed current as at 2026-07-20. 2026 tightening sequence to date: 3.60% -> 3.85% (decision 3 Feb 2026, mr-26-03, eff. 4 Feb 2026), -> 4.10% (decision 17 Mar 2026, eff. 18 Mar 2026, a 5-4 split), -> 4.35% (decision 5 May 2026, eff. 6 May 2026), unchanged 16 Jun 2026. Since the Reserve Bank Reforms Act 2025 (Cth) commenced the decision-maker is the Monetary Policy Board (not the former single Reserve Bank Board), and votes are published: the May 2026 decision was 8-1 (eight to raise 25bp, one to hold at 4.10%). The RBA does not set the cash rate by legal instrument - it is an operational target implemented through open market operations and the Exchange Settlement Account remuneration corridor (ES balances remunerated at the target).
