Applying the correct rate in code

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

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

// 2. Fetch current Singapore GST rates (no auth required)
const rates = await fetch('http://localhost:3000/api/v1/rates/SG').then(r => r.json());
// → { standard_rate: 9, reduced_rates: [] }

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

About Singapore GST

Singapore completed a two-step GST rise to 9% in January 2024, cushioned by an assurance package of household vouchers — the city-state's first rate change since 2007. The SGD 1 million registration threshold is one of the highest in the world, keeping most small businesses outside the system. Overseas vendors selling digital and imported services to Singapore consumers must register under the Overseas Vendor Registration regime once global turnover tops SGD 1 million and local B2C sales exceed SGD 100,000.

GST in Singapore is administered by the Inland Revenue Authority of Singapore (IRAS). Before applying any zero-rate or exemption to a Singapore business customer, validate their registration first.
