SST Registration Malaysia 2026: Who Must Register, Threshold & Steps for SMEs

Sales Tax vs Service Tax: Two Separate Taxes, Not One

SST gets lumped together as a single acronym. It isn't. SST is two separate taxes administered by RMCD (Royal Malaysian Customs Department) under two separate Acts, and understanding the split determines which threshold applies to you.

Sales Tax is a single-stage tax imposed on the manufacturer. If you produce taxable goods in Malaysia, or import taxable goods, Sales Tax applies at 5% or 10% on the sale value. The manufacturer collects it once. It does not cascade through the supply chain the way GST did.

Service Tax is a single-stage tax on the consumer of prescribed taxable services. If you provide services in a listed category, professional services, hospitality, telecommunications, food and beverage, and others, you charge Service Tax at 6% or 8% to your customers. Since March 2024, the rate increased to 8% for most categories, while certain hospitality and tourism services remain at 6%.

These two taxes operate independently. A restaurant in Kuala Lumpur that produces its own sauces for internal use is not automatically a Sales Tax manufacturer, the manufacturing is incidental to the service. A JB law firm that also sells legal reference books does not necessarily trigger Sales Tax. The primary activity of your business governs. When in doubt, confirm with RMCD or a licensed tax agent which tax applies to your specific business model.

Who Is Legally Required to Register?

Registration is mandatory once you cross the relevant threshold. There is no grace period beyond the 28-day registration window. Not knowing you had to register is not a defence RMCD accepts.

For Sales Tax, you must register if you are:

• A manufacturer of taxable goods in Malaysia with annual taxable turnover ≥ RM500,000
• An importer of taxable goods into Malaysia, no threshold applies, importers must register before any import
• A licensed manufacturer seeking exemptions or drawback under the Sales Tax Act 2018

For Service Tax, you must register if you are:

• A provider of taxable services listed in the First or Second Schedule of the Service Tax Regulations with annual taxable value ≥ RM1,500,000
• A credit card or charge card service provider, no threshold, registration is mandatory regardless of size
• A professional services firm (legal, accounting, engineering) above the RM1,500,000 taxable services threshold

Threshold monitoring uses a rolling 12-month calculation, not your financial year. The moment any consecutive 12-month window exceeds RM500,000 or RM1,500,000, the clock starts. You have 28 days to submit your registration via MySST.

SST Registration Thresholds and Rates for 2026

Here is the summary of who registers for what, at what threshold, and at what rate, the three numbers your accountant needs to know.

Tax Type	Who It Applies To	Registration Threshold	Tax Rate	Governing Act
Sales Tax	Manufacturers of taxable goods	RM500,000 annual taxable turnover	5% or 10% (depends on goods classification)	Sales Tax Act 2018
Service Tax (standard)	Providers of prescribed taxable services	RM1,500,000 annual taxable value of services	8% (most services); 6% (hospitality, tourism)	Service Tax Act 2018
Service Tax (credit cards)	Credit card and charge card operators	No threshold, register before operations begin	8%	Service Tax Act 2018

Both thresholds count taxable turnover, not total revenue. A manufacturer in Penang with RM2 million total revenue but only RM400,000 from taxable goods is not yet liable for Sales Tax. Only the taxable goods revenue counts toward the threshold. This matters for mixed-activity businesses: retailers who do some light assembly, traders who do custom fabrication, or service firms that also sell physical products.

How to Register SST via MySST Portal, 7 Steps

All SST registration happens online at RMCD's MySST portal, mysst.customs.gov.my. Walk-in at RMCD branches is possible but slower. Before you log in, prepare these documents:

• SSM certificate, Form 9 (Sdn Bhd / Bhd) or Form D/A (sole proprietor or partnership)
• MyKad or passport of all directors or business owners
• Business address proof, utility bill or tenancy agreement
• Bank account details (for any refund scenarios)
• List of taxable goods with HS codes (for Sales Tax) or description of taxable services (for Service Tax)

Then follow these steps in the MySST portal:

1. Create your MySST account, at mysst.customs.gov.my, click "Register" and complete the business profile. If your company already has a RMCD account from previous customs dealings, use those credentials.
2. Select your application type, choose Sales Tax registration, Service Tax registration, or both if your business involves taxable manufacturing and taxable services separately.
3. Complete Form SST-01, enter your business registration number (SSM), the nature of your taxable goods or services, your estimated annual turnover, and the date you became liable, that is, the first date your rolling 12-month turnover exceeded the threshold.
4. Upload supporting documents, upload scanned copies of your SSM certificate, identification documents, address proof, and product or service descriptions. Keep each file under 2MB; RMCD's portal rejects oversized uploads without a clear error message.
5. Review before submitting, RMCD cannot amend approved applications easily. Double-check your effective liability date and the list of taxable goods or services before clicking submit. Save your application reference number.
6. Respond to RMCD queries promptly, RMCD may contact you via email or the portal messaging system requesting clarification or additional documentation. Unanswered queries stall approval indefinitely.
7. Receive your SST registration number, RMCD approves and issues your registration certificate via the portal. Print it. Your SST registration number must appear on every tax invoice you issue from your effective date onward.

Your Effective Date, Why the Backdating Rule Bites

When RMCD approves your registration, the effective date is not the approval date. It is the date you became liable, the day your rolling 12-month taxable turnover first crossed the threshold.

What this means in practice: your taxable turnover crossed RM500,000 on 1 March 2026. You only registered on 30 June 2026, three months late. Your effective registration date is still 1 March 2026. You owe Sales Tax on every taxable sale from March, April, and May, transactions you invoiced without Sales Tax. Those customers received invoices without tax. Whether you can recover Sales Tax from them retroactively is your commercial problem, RMCD does not care about your relationship with your customers.

The 28-day window is designed to cap your exposure. Register on day 27 and your backdated liability covers just 27 days. Wait three months and you face a much larger back-filing computation, plus the fine for late registration.

Your effective date is also the anchor for your first taxable period. Your first SST return covers the period from your effective date to the end of that 2-month taxable period. If your effective date falls mid-period, your first return is a partial period, shorter than the standard 2 months.

SST Filing Schedule, Bimonthly Returns

Once registered, SST runs on a bimonthly (every 2 months) filing cycle. Your taxable period is set by RMCD at registration. For most businesses, it follows the standard calendar bimonths. Returns and payments are due by the last day of the month following each taxable period.

Taxable Period (2026)	Return & Payment Due	Sales Tax Form	Service Tax Form
January – February	31 March 2026	SST-02	SST-02A
March – April	31 May 2026	SST-02	SST-02A
May – June	31 July 2026	SST-02	SST-02A
July – August	30 September 2026	SST-02	SST-02A
September – October	30 November 2026	SST-02	SST-02A
November – December	31 January 2027	SST-02	SST-02A

Submissions are made via the MySST portal. Payment can be made by FPX, cheque, or direct debit. Late returns and late payments both attract penalties, the 10% surcharge starts the day after the due date. A nil return must be filed even if you had zero taxable transactions in the period. "Nothing happened this month" is not a reason to skip the return.

Penalties for Late or Non-Registration

The penalties under SST are not administrative slaps. Failure to register when you are liable is a criminal offence under the Sales Tax Act 2018 and Service Tax Act 2018, with every taxable transaction from the liability date constituting a continuing offence.

Offence	Maximum Penalty	Legislation Reference
Failure to register when liable	Fine up to RM30,000 or imprisonment up to 3 years, or both	Sales Tax Act 2018 s.86 / Service Tax Act 2018 s.78
Late payment of SST	10% surcharge (≤30 days late); additional 15% (31–60 days); additional 15% (61–90 days)	Sales Tax Act 2018 s.36 / Service Tax Act 2018 s.26
Failure to submit SST return	Fine up to RM50,000 or imprisonment up to 3 years, or both	Sales Tax Act 2018 s.47 / Service Tax Act 2018 s.37
Under-declaration of taxable value	Fine up to 3× the amount under-declared, plus the tax owed	Sales Tax Act 2018 s.83 / Service Tax Act 2018 s.75

In practice, RMCD more commonly imposes financial penalties and demands back-tax rather than pursuing criminal prosecution for first-time registration failures, particularly when businesses come forward voluntarily. But the criminal exposure is real. If RMCD identifies you through a routine audit or a tip-off from a competitor or customer in Shah Alam or Ipoh, voluntary disclosure is no longer on the table.

Voluntary Registration, Who Should Consider It Early

Both the Sales Tax Act 2018 and Service Tax Act 2018 allow voluntary registration before you hit the mandatory threshold. Three situations make it worth doing early.

You are approaching the threshold. If your taxable turnover sits at RM400,000 and growing at 20% per year, you will hit RM500,000 mid-cycle. Registering now avoids the scramble and backdating risk when you cross the line in a few months. It also gives you time to update your invoicing system and notify customers before SST becomes mandatory.

Your customers require it. SST-registered manufacturers can purchase inputs from other SST-registered manufacturers without paying Sales Tax, under the manufacturer-to-manufacturer exemption mechanism. If your end customers are manufacturers too, they may demand your SST registration number before purchasing. Without registration, you may lose contracts to registered competitors in Petaling Jaya or Selangor industrial parks.

You want a clean setup from day one. Switching to SST-inclusive pricing after you have been selling without it is disruptive, you either absorb the cost or renegotiate with customers. Starting with SST baked in from the beginning is cleaner.
