SST invoice format Malaysia: Requirements & tax codes (2026)

Key Takeaways:

• The SST invoice format in Malaysia must include specific fields, such as your SST registration number, a clear tax breakdown, and sequential invoice numbers.

• Sales tax (5% or 10%) and service tax (6% or 8%) use different tax codes, and using the wrong one can distort your SST-02 return.

• Malaysia's e-Invoicing system does not replace SST requirements: businesses must ensure their e-Invoices still contain the required SST invoice particulars.

The SST invoice format in Malaysia refers to the exact fields, layout, and tax breakdown that the Royal Malaysian Customs Department (RMCD) expects on every sales tax or service tax invoice you issue.

Get it wrong, and you risk failed audits, rejected B2B exemption claims, or penalties under the Sales Tax Act 2018 and Service Tax Act 2018.

This guide breaks down every mandatory field, walks through the tax codes for sales tax and service tax, and shows you how to calculate SST with a worked example in RM.

It also covers common mistakes and how SST invoicing connects to Malaysia's e-Invoicing (MyInvois) rollout.

What is an SST invoice, and why does the format matter?

A tax invoice is the document a business issues to charge and record sales tax or service tax on a supply. This is different from a plain commercial invoice, which lists what you sold and the amount due but does not show any tax breakdown.

Under Malaysia's Sales Tax Act 2018 and Service Tax Act 2018, only businesses registered with RMCD can issue an SST tax invoice that charges sales tax or service tax.

The invoice must follow prescribed particulars set out in the SST regulations, and that prescribed layout is the SST invoice format this guide covers.

Getting the format right matters because RMCD uses your invoices to verify your SST-02 return, approve B2B exemption claims, and check compliance during an audit. An invoice missing required particulars may not be accepted as sufficient documentation during an RMCD review or audit.

Mandatory fields on a Malaysian SST invoice

The Royal Malaysian Customs Department (RMCD) sets out prescribed particulars for every SST tax invoice. Miss one of these fields, and your invoice may not hold up during an audit or a customer's exemption review.

You can issue invoices in hard copy or electronically, and in Bahasa Malaysia or English.

Invoice and party identification details

Every SST invoice should include:

• Invoice serial number: Number invoices sequentially. Gaps or duplicate numbers may raise questions during an audit.

• Invoice date

• Seller's details: Business name, address and identification number.

• SST registration number: Only SST-registered businesses can issue SST tax invoices.

• Customer's details (where applicable): If your customer is SST-registered, include their business name and SST registration number to support exemption claims.

RMCD also recognises electronic tax invoices, provided they contain all the required information and are delivered electronically to the customer.

Goods, services and SST breakdown

Your invoice should also include:

• Description of the goods or services

• Quantity and unit price

• Total amount before SST

• Applicable SST rate

• SST amount shown separately

Show the SST rate and amount clearly on the invoice rather than hiding it within the item price. This makes reconciliation easier and aligns with RMCD's invoicing requirements.

Correcting an SST invoice

If you need to amend an invoice:

• Issue a credit note or debit note instead of editing the original invoice.

• Include the prescribed particulars required by RMCD.

• Reference the original invoice being corrected.

• Reflect the adjustment in your next SST-02 return.

Sales tax invoices vs service tax invoices

Malaysia's SST framework includes sales tax and service tax, but most businesses only deal with one of them. Which type of SST invoice you issue depends on what your business does.

Here’s a quick overview:

Sales tax invoices

Sales tax invoices are issued by registered manufacturers of taxable goods, including businesses carrying out taxable subcontract manufacturing.

Sales tax is charged once, at the point of manufacture or import. Businesses further down the supply chain, such as wholesalers and retailers, generally do not issue sales tax invoices because the tax has already been paid earlier in the chain.

Service tax invoices

Service tax invoices are issued by registered businesses providing taxable services, such as professional services, hospitality, telecommunications and digital services.

Unlike sales tax, service tax is charged when the service is supplied. If your business provides taxable services, the invoice you send your customer will typically be the service tax invoice for that transaction.

What's the difference?

Both sales tax and service tax invoices must contain the prescribed particulars required by the Royal Malaysian Customs Department (RMCD). The key difference is which tax regime your business is registered under, as this determines the tax rate and SST treatment you apply.

SST tax codes explained

Tax codes help your accounting software apply the correct SST treatment to each transaction and report it accurately in your SST-02 return.

There isn't a standard list of SST tax codes prescribed by RMCD. Instead, each accounting platform uses its own naming convention, although the underlying tax treatments are broadly the same.

Sales tax codes

Sales tax codes are typically grouped by tax treatment, such as:

• 10% sales tax

• 5% sales tax

• 0% or exempt sales

Some accounting systems also include separate codes for different types of sales tax exemptions, depending on your reporting requirements.

Service tax codes

Service tax codes follow the same principle. Most taxable services use the 8% rate, while certain services, such as food and beverage, telecommunications, parking and logistics, remain subject to 6% service tax.

You should also create separate tax codes for exempt transactions, such as eligible B2B service tax exemptions, so they are reported correctly in your SST-02 return.

SST rates in 2026 and how to calculate SST on your invoice

Malaysia's SST rates depend on what your business sells.

Sales tax is charged at 5% or 10%, depending on the taxable goods, while service tax is generally 8%, with certain services (including food and beverage, telecommunications, parking and logistics) remaining at 6%.

Only SST-registered businesses should charge SST on their invoices.

For example, say your business provides IT consulting services and invoices a client RM10,000. The invoice would look like this:

Show the subtotal, SST amount and total payable as separate line items on the invoice. If you supply taxable goods instead, apply the appropriate 5% or 10% sales tax rate for those goods.

If you're unsure which rate applies, confirm the correct classification before issuing the invoice, as applying the wrong SST rate is a common compliance mistake.

Common SST invoicing mistakes to avoid

Most SST invoice rejections trace back to a handful of recurring errors. Check your templates against this list before you send your next invoice.

• Leaving out your SST registration number, which makes the invoice invalid as proof of a taxable supply.

• Bundling the SST amount into the price instead of showing it as its own line, which hides the tax from your customer and from RMCD.

• Reusing an old rate on your invoice template after a rate change, so services get billed at the wrong tax rate.

• Using non-sequential or duplicate invoice numbers, which is one of the first things RMCD checks during an audit.

• Skipping the buyer's SST number on a B2B invoice, which can cause your customer's exemption claim to fail even though the underlying transaction qualifies.

Review your invoice template every time RMCD announces a rate or scope change, not just once a year.

SST invoices and Malaysia's e-Invoicing (MyInvois) rules

Malaysia's e-Invoicing system (MyInvois) does not replace your SST obligations.

If you're required to issue both an e-Invoice and an SST tax invoice, a single e-Invoice can generally satisfy both requirements provided it contains all the prescribed SST invoice particulars.

An e-Invoice is a structured XML or JSON document validated through LHDN's MyInvois platform. The PDF or visual version that you send to your customer is simply a human-readable representation of that validated e-Invoice.

Who needs to comply?

LHDN has introduced e-Invoicing in phases based on annual turnover:

*A penalty-free relaxation period applies until December 2027.

If your business is already required to use MyInvois, make sure your e-Invoice includes all the information required for an SST tax invoice, such as your SST registration number, invoice serial number and SST breakdown.

This helps you meet both LHDN's e-Invoicing requirements and RMCD's SST invoicing requirements using a single document.

Frequently asked questions (FAQs)

Is an SST invoice different from a normal tax invoice in Malaysia?

No, in Malaysia the terms mean the same thing. Only businesses registered with RMCD for sales tax or service tax can issue one, and it must follow the prescribed particulars set out in the Sales Tax Act 2018 or Service Tax Act 2018. A plain commercial invoice, by contrast, does not need to show any tax details.

Do I need to register for SST before I can issue an SST invoice?

Yes. You can only issue an SST tax invoice after RMCD approves your SST registration. Registration requirements depend on your taxable activity and applicable threshold. Charging SST on an invoice before you are registered, or without a registration number on the invoice, makes the document invalid for tax purposes.

Can small businesses use a simplified SST invoice format?

No. Malaysia's former GST system allowed a simplified invoice for small-value sales, but SST does not carry over that option. Every SST-registered business follows the same prescribed particulars regardless of size, so check your invoice against the full checklist even for small transactions.

What happens if my SST invoice is missing required details?

An invoice missing required details, such as your SST registration number or a separate tax breakdown, can be rejected as evidence during an RMCD audit. It can also cause a customer's B2B exemption claim to fail, even if the underlying transaction was valid, and repeated errors can draw penalties under the Sales Tax Act 2018 or Service Tax Act 2018.

How often do I need to file my SST-02 return?

Registered businesses file the SST-02 return bimonthly, covering a two-month taxable period, with payment due by the last day of the following month⁵. You still need to submit a nil return for periods where you have no SST to declare.

How can I check if a business is SST-registered before accepting its invoice?

You can search the MySST portal directly to confirm whether a business holds a valid SST registration number before accepting its invoice as a tax invoice. This matters most when you are relying on the invoice to support a B2B exemption claim, since an invoice from an unregistered business cannot carry valid SST.
