GST

Goods and Services Tax (GST) is a broad-based consumption tax levied on the supply of goods and services in Singapore. At 9% (from 2024), it’s a material cost — or revenue item — for many businesses. Knowing when you must register, and what compliance looks like after, is essential. The GST Threshold In Singapore, GST registration becomes mandatory once your taxable turnover exceeds — or is expected to exceed — S$1 million in a 12-month period. This is measured on a retrospective or prospective basis. Basis Condition Action Required Retrospective Turnover in last 12 months exceeded S$1M Register within 30 days of end of that period Prospective Reasonable grounds to expect next 12 months > S$1M Register within 30 days of making that determination 💡 From 1 Jan 2024, the GST rate in Singapore is 9%. Charging GST without being registered is a criminal offence — as is failing to register when required. Mandatory vs Voluntary Registration Beyond mandatory registration, businesses can voluntarily register for GST even if turnover is below S$1 million. This may be beneficial if your customers are mostly GST-registered businesses (who can claim the GST back) or if you have significant GST inputs to recover. Voluntary registration requires IRAS approval and comes with a 2-year commitment to remain registered. What Registration Means for Your Business Filing Obligations GST-registered businesses file quarterly returns with IRAS, typically within one month of the end of each accounting period. The net GST (output tax minus input tax) is either paid to IRAS or refunded, depending on your position. Penalties for Late Registration IRAS takes late or non-registration seriously. Penalties can include a fine of up to S$10,000, backdated GST liability (meaning you owe GST you didn’t collect), and in serious cases, prosecution.
