SST Invoice Requirements for Malaysian Businesses (2026 Guide)

What Is SST, and Who Needs to Charge It?

Malaysia's Sales and Service Tax (SST) replaced the Goods and Services Tax (GST) in September 2018 and is administered by the Royal Malaysian Customs Department (RMCD). Unlike GST, SST is not one unified tax — it is two separate taxes. Sales Tax applies to the manufacture and import of taxable goods, while Service Tax applies to specific categories of taxable services, from professional consulting to food and beverage.

A key structural difference from GST is that SST has no input tax credit mechanism. Businesses cannot reclaim the SST they pay on their own purchases, so it behaves as a final, non-recoverable cost that moves through the supply chain. This makes correct registration and invoicing especially important, since an error compounds rather than nets out later.

Registration Thresholds

Registration is triggered once your taxable turnover crosses a threshold, assessed on a rolling 12-month basis using either actual past turnover or expected future turnover. Thresholds vary by category:

Manufacturers (Sales Tax): RM500,000
Professional services — consulting, legal, accounting, IT, engineering, architecture, online platforms: RM500,000
Rental and leasing of tangible assets or commercial property: RM1,000,000
F&B, private healthcare, and construction services: RM1,500,000
Some categories, such as credit and charge card providers and customs agents, must register immediately with no threshold

If your turnover sits below the relevant threshold, you can apply for voluntary registration. This is worth considering if you need to issue formal tax invoices for corporate clients who require them, though approval sits with RMCD's discretion.

Current Rates

Sales Tax is charged at the point of manufacture or import, and the applicable rate depends on the product's Harmonized System (HS) code. Check RMCD's official schedule for your specific goods rather than assuming a flat rate applies.

Service Tax follows a two-tier structure:

8% standard rate — most professional and advisory services, including consulting, legal, IT, accounting, and management, plus advertising and general asset rental
6% preserved rate — food and beverage, telecommunications, internet access, parking, and logistics or courier services
A flat RM25 per card per year applies to credit and charge card issuance

Rates for certain categories, including rental, construction, healthcare, and education, have shifted more than once since mid-2025. If your business falls into one of these, verify the current rate directly with RMCD before invoicing a client.

Mandatory Fields on an SST Invoice

A compliant tax invoice under the Sales Tax Regulations 2018 and Service Tax Act 2018 must include:

Your SST registration number
The words "Tax Invoice" stated clearly
Invoice date and a unique serial number
Your business name and address
A description of the goods or services provided
SST charged shown as a separate line item, not bundled into the price

Missing any of these fields can invalidate the invoice for the client's own tax purposes, and non-compliance carries statutory penalties.

E-Invoicing: A Separate Obligation

Malaysia's e-invoicing mandate, run through LHDN's MyInvois system, is being rolled out in phases and is distinct from SST registration. Under the current phase, businesses with annual turnover above RM1 million must submit structured e-invoices in real time. Below RM1 million, you are currently exempt from e-invoicing — but you still need to register for and issue compliant SST invoices once your turnover crosses the relevant SST threshold above. These are two separate obligations that do not automatically align, so crossing one threshold does not mean you have crossed the other.

Common Mistakes to Avoid

Premature charging: applying for registration does not authorise you to charge tax — wait for your SST number to be confirmed before adding SST to any invoice.
Mixed-rate invoices: if you provide services taxed at different rates, such as consulting at 8% alongside logistics coordination at 6%, itemise them separately rather than applying one rate across the whole invoice.
Missing invoice fields: omitting the SST number or the "Tax Invoice" header, or folding tax into the price instead of showing it as its own line item, can invalidate the invoice.

Verify Before You File

Malaysia's SST rates, thresholds, and e-invoicing rules have changed more than once in recent years, and further adjustments are likely. Treat this guide as a starting point rather than a substitute for RMCD's official guidance or advice from a licensed tax professional, particularly before your first filing.

FAQ

Is SST the same as GST?

No. GST was a multi-stage tax with input tax credits, so businesses could reclaim tax paid on their purchases. SST is single-stage with no input tax recovery, so it functions as a final cost that gets passed through pricing rather than reclaimed.

Do I need to charge SST if I'm not registered?

No, and you should not. Charging SST without an active registration is a compliance offence. Unregistered businesses should invoice at the net amount with no tax reference until their SST number is confirmed.

Does my small business need to comply with e-invoicing in 2026?

Only if your annual turnover exceeds RM1 million. Below that threshold, you are exempt from the e-invoicing mandate, though you may still owe SST separately if your turnover crosses the relevant SST registration threshold.

What is the B2B Service Tax exemption?

It is a relief mechanism that lets registered businesses avoid paying Service Tax again when buying the same category of service from another registered provider, such as one IT consultancy subcontracting to another. Both parties need to be registered, and the buyer must keep records to support the exemption.
