Malaysian rules & edge cases
SST in Malaysia is two single-stage taxes under the Royal Malaysian Customs Department (JKDM), read here from its MySST FAQ pages and checked on 2026-11-08. Service tax is charged on taxable services; sales tax is charged once by the manufacturer or importer on taxable goods — a normal retailer does not add it at the till. The table below is the engine's own output for a RM 1,250.00 net amount, not a typed example:
| Rate | Effective from | Tax on RM 1,250.00 | Total |
|---|---|---|---|
| 8% | 2024-03-01 | RM 100.00 | RM 1,350.00 |
| 6% | 2024-03-01 | RM 75.00 | RM 1,325.00 |
| 10% | 2025-07-01 | RM 125.00 | RM 1,375.00 |
| 5% | 2025-07-01 | RM 62.50 | RM 1,312.50 |
- Service tax 8% applies to all taxable services except four categories that stay at 6%: food and beverage, logistics, telecommunications and parking. The 8% standard rate took effect on 2024-03-01, while those four categories stayed at or entered the 6% rate.
- Sales tax 5% (and specific rates) applies under the Sales Tax (Rate of Tax) Order 2025 from 2025-07-01. Goods in the Sales Tax (Goods Exempted from Tax) Order 2025 are at 0%. Anything in neither order is 10% from 2025-07-01.
- Single stage. Sales tax is charged once, by the manufacturer or importer — not by a normal retailer at the till. Service tax is charged by the provider of a taxable service, so it is the one a shop, hotel or platform actually adds to an invoice.
- Rounding. The tax is rounded half-up to the nearest sen on integer sen, never on floating point: RM 100.00 on RM 1,250.00 at 8% is exact, and a supplier's accounting system may still differ by a sen.

FAQ
Does this tool decide whether my supply is taxable?
No. It only does the arithmetic once you have chosen a rate. Whether a service or a good is taxable, and which order a good falls under, is JKDM MySST guidance — read the MySST FAQ and your supply agreement before you charge a customer, because a wrong rate is a compliance problem, not a rounding problem.
How is the tax rounded, and why might my supplier differ by a sen?
The tax is rounded half-up to the nearest sen: 0.07 at 8% gives 0.01. The arithmetic is done on integer sen, so there is no floating-point error. A supplier system that rounds per line, or that rounds the net for extract instead of the tax, can still land one sen away — check one line against this calculator before you automate the rest.
Can I add sales tax to a retail price at the till?
No. Sales tax is a single-stage tax charged by the manufacturer or importer of taxable goods; a normal retailer does not add it. Use the sales rates here to work out what a wholesale cost already includes, not to add a percentage to a shelf price. Service tax is the one a provider of a taxable service adds to an invoice.
Is my amount uploaded anywhere?
No. The calculator is static JavaScript in your browser: open the Network tab and you will see zero requests. An invoice total never leaves the machine.
