In practical terms, the billing path mostly determines who is responsible for registering, invoicing and remitting the tax to the Royal Malaysian Customs Department (RMCD) — not the rate itself at current settings, which is why this calculator applies the same 8% regardless of which option you select. Registration is covered in our guide to SST on digital marketing.
This tool exists to make the true, tax-inclusive cost of a multi-platform ad budget visible in one place rather than discovered platform-by-platform on separate invoices — useful when budgeting a full year of spend where the SST line item is easy to underestimate across three or four platforms at once.
Treat the output as a planning estimate: SST registration thresholds, specific exemptions and invoicing treatment can vary by business structure, so confirm your exact situation via the MySST portal or a tax adviser rather than relying on this tool alone. For rates and registration, see our SST Malaysia guide.
Budgeting ad spend before tax? Pair this with the Google Ads cost calculator, and if you're also tracking e-invoicing obligations alongside this, see the e-invoice deadline checker.
Selling on a marketplace, not just advertising on one?
The same 8% SST applies to Shopee, Lazada and TikTok Shop's own commission, transaction and platform support fees, not just to ad spend — this calculator covers ad spend specifically, so for a live selling session's full fee stack (already SST-inclusive), see the live commerce ROI calculator and what a live selling session costs in Malaysia.
