SST Calculator Malaysia FAQs
What is an SST calculator used for?
An SST calculator helps you estimate the SST amount, the total including SST, or the amount before SST. It is useful when checking invoice amounts, quotations, and simple business records.
How do I calculate SST from an amount before tax?
To add SST, multiply the amount before SST by the SST rate. Then add the SST amount to the original amount to get the total including SST.
How do I remove SST from a total that already includes SST?
To remove SST, divide the SST-inclusive total by 1 plus the SST rate as a decimal. For example, with 8% SST, divide the total by 1.08 to estimate the amount before SST.
What SST rate should I use in Malaysia?
Use the rate that applies to your taxable service or goods category. This calculator includes common percentage rates such as 6%, 8%, 10%, 5%, 0%, and a manual rate option, but you should confirm the applicable treatment with current MySST or RMCD guidance.
What is the difference between sales tax and service tax?
Service tax generally applies to prescribed taxable services provided by a taxable person in Malaysia. Sales tax is a single-stage tax on imported or locally manufactured goods, depending on the goods classification and current rules.
Can this SST calculator confirm whether my item is taxable?
No. The calculator only performs the arithmetic. Taxability depends on the service category, goods classification, exemptions, registration status, and current SST rules.
Can I use this result for SST filing?
Use the result as a checking estimate only. Before filing or issuing tax documents, confirm the SST category, rate, taxable period, and invoice treatment using official guidance or a qualified tax adviser.
