Add or extract SST from a price

SST calculator (Malaysia)

Calculate the Sales and Service Tax (SST) amount on a price in Malaysia, or work backward from a tax-inclusive price.

Formula

tax-exclusive price = tax-inclusive price ÷ (1 + rate) · tax amount = tax-exclusive price × rate

Assumptions

• Default rate (8%) reflects the common Service Tax rate — Sales Tax on goods is commonly 10%, with some categories at 5% or exempt.
• Does not determine which SST category a specific good or service falls under — check RMCD guidance for your item.

Frequently asked questions

Should I use the Sales Tax or Service Tax rate?
Sales Tax applies to taxable goods (commonly 10%, some categories 5% or exempt). Service Tax applies to prescribed services like consulting, F&B, and digital services (commonly 8%, some categories remain at 6%). Check the RMCD MySST portal for your specific category.

How do I remove SST from a price I was quoted?
Set "Price already includes SST" to 1 and enter the tax-inclusive price — the calculator solves backward for the pre-tax amount.
