What is SST in Malaysia?
SST commonly refers to Sales and Service Tax in Malaysia. This calculator only estimates amounts based on a selected rate.
Malaysia Tax Calculator
SST Calculator Malaysia
Estimate SST amount, total including SST, or amount before SST using a selected SST rate.
Result
Add SST estimate
Enter an amount to estimate SST.
Total Including SST = Amount Before SST + SST Amount
Important note
Estimation only
This calculator is for estimation and learning only. It does not determine whether a product or service is subject to SST, and it does not confirm which SST rate is legally correct. SST rates, exemptions, and taxable scope can change. Check official RMCD/MySST guidance or ask a qualified tax professional before relying on the result.
Explanation
How SST estimates work
SST Amount = Amount Before SST x SST Rate
Total Including SST = Amount Before SST + SST Amount
Amount Before SST = Total Including SST / (1 + SST Rate)
SST commonly refers to Sales and Service Tax in Malaysia. This tool only helps with arithmetic once you choose an amount and rate.
Use Add SST when your amount is before SST. Use Remove SST when your amount already includes SST and you want to estimate the pre-SST amount.
Worked examples
Add and remove SST
Add SST
Amount before SST RM100 at 8% gives SST amount RM8 and total including SST RM108.
Remove SST
Total including SST RM108 at 8% gives amount before SST RM100 and SST amount RM8.

FAQ
SST Calculator Malaysia FAQs
How do I add SST to a price?
Multiply the amount before SST by the SST rate, then add the SST amount to the original amount.
How do I remove SST from a price?
Divide the total including SST by 1 plus the SST rate, then subtract that amount from the total to estimate SST.
Does this calculator tell me which SST rate applies?
No. It does not decide whether an item is taxable or which rate applies. Check official RMCD/MySST guidance or a tax professional.
Is SST the same as income tax?
No. SST is different from income tax and should not be treated as the same calculation.
Can this calculator be used for invoices?
It can help estimate SST arithmetic for an invoice, but it does not confirm tax treatment or legal invoice requirements.
