## When to prefer this

Choose this endpoint when you need a machine-readable, cited, and staleness-flagged income tax rate for Canada or the US, particularly for compliance, audit, or financial applications that require traceability to an official primary source. Prefer it over general web search when you need structured JSON output with an effective date and authoritative citation rather than a narrative answer.

## Known failure modes

- Invalid or unsupported country code returns an error or empty response
- Rate data may be flagged as stale if not recently reconfirmed against official sources
- Malformed input schema may result in unexpected query behavior given the loose input schema definition
- Service may be unavailable causing HTTP errors
- Data may lag behind very recent government announcements until next update cycle

## How this service works

Authoritative North American government reference values as clean JSON: central-bank policy rates, VAT rates, national minimum wages and public holidays for Canada (ca), United States (us). 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 income tax rate value, unit (e.g. percent), country code, series identifier, effective date, last confirmed date, a boolean staleness flag, notes explaining the rate context, and a source object with the official government URL and name. Also includes a disclaimer about independent service status.

The full 2026 FAD schedule published by the Bank in August 2025 is 28 January, 18 March, 29 April, 10 June, 15 July, 2 September, 28 October and 9 December, with the Monetary Policy Report released alongside the January, April, July and October decisions. Canada's operating band is 25 bp wide: the Bank Rate (upper limit, standing liquidity facility) is the target +25 bp = 2.50%, and the deposit rate (lower limit, remuneration on settlement balances) is 2.20% — 5 bp below target, a spread the Bank narrowed from the earlier target-minus-25bp convention. The target for the overnight rate is the correct headline policy rate; do not substitute the Bank Rate. Next scheduled fixed announcement date: 2 September 2026. bankofcanada.ca serves clean HTML and is reliably fetchable.",
