Frequently asked questions
Common questions about GST, VAT, SST, and PPN across Asia.
Tax-exclusive means the amount you entered does NOT include tax — the tax is calculated on top and added to arrive at the final total. Tax-inclusive means the amount you entered already includes the tax — the calculator works backwards to extract the tax component from the total. Invoice amounts are usually tax-exclusive; retail prices are often tax-inclusive.
Singapore's GST rate is 9%, effective 1 January 2024. It was previously 8% (from 1 Jan 2023) and 7% before that. Businesses with taxable turnover exceeding S$1 million in a 12-month period must register for GST. Certain supplies are exempt or zero-rated (e.g. financial services, residential property, exports).
India uses a four-slab structure: 5%, 12%, 18%, and 28%. Most everyday goods are at 5% or 12%. Most services (including professional services, SaaS, digital products) are taxed at 18%. Luxury and sin goods attract 28%. There is also a 0% / nil-rated category for essential items like fresh produce. The correct slab depends on the HSN code (goods) or SAC code (services).
Malaysia replaced GST with a two-part SST in 2018. Service Tax (currently 8%, raised from 6% in March 2024) applies to prescribed services — restaurants, hotels, professional services, digital services. Sales Tax applies to taxable manufactured goods and certain imported goods, at either 5% or 10% depending on the category. Most B2B software and consulting services fall under Service Tax at 8%.
Vietnam periodically extends a temporary reduction from 10% to 8% for many goods and services as an economic stimulus. This reduction has been renewed multiple times. The 10% standard rate applies to most remaining categories. Certain essential goods (clean water, fertilisers, medicine) permanently attract 5%. Always verify the current status with your Vietnamese tax advisor, as these policies change with government decrees.
Yes, in most countries registered businesses can claim back (offset) GST/VAT paid on business inputs against the GST/VAT they collect from customers. This is called input tax credit. You only remit the net amount (output tax − input tax) to the tax authority. This means tax is effectively borne only by the end consumer, not by businesses in the supply chain. Rules differ — consult a local tax advisor for your specific situation.
