curl http://localhost:3000/api/v1/rates/AU
# No authentication required for rate lookups

# Response:
# { "country_code": "AU", "tax_type": "gst",

#   "currency": "AUD", "last_updated": "2026-01-01" }

Applying the correct rate in code

For B2B sales to Australia, validate the customer's ABN first — a verified registration is typically required for correct invoicing and zero-rated exports. For B2C, charge the Australia GST rate where registration rules require it.

// 1. Validate the customer's Australia tax ID
const check = await fetch(
  'http://localhost:3000/api/v1/validate/AU/CUSTOMER_TAX_ID',
  { headers: { Authorization: 'Bearer YOUR_API_KEY' } }
).then(r => r.json());

// 2. Fetch current Australia GST rates (no auth required)
const rates = await fetch('http://localhost:3000/api/v1/rates/AU').then(r => r.json());
// → { standard_rate: 10, reduced_rates: [] }

// 3. Apply the correct treatment for your supply
applyRate(check.valid && isB2BExport ? 0 : rates.standard_rate);

About Australia GST

Australia's GST has stayed at exactly 10% since its introduction in 2000 — any change requires the unanimous agreement of all states and territories, which has proven politically impossible. Instead of reduced rates, whole categories like basic food, health and education are "GST-free" (zero-rated). Foreign sellers of digital products and low-value goods to Australian consumers must register once sales exceed AUD 75,000, under rules that pioneered the taxation of inbound e-commerce.

GST in Australia is administered by the Australian Taxation Office (ATO). Before applying any zero-rate or exemption to a Australia business customer, validate their registration first.
