SST Registration Threshold in Malaysia: The Limits, the 12-Month Test and What to Do

By Axecta Management Services, Kuala Lumpur · Last verified: 29 October 2026

Why the SST threshold matters

Sales and Service Tax (SST) is administered by the Royal Malaysian Customs Department through the MySST portal. Unlike income tax, which follows your accounting year, SST registration is triggered by a rolling 12-month value of taxable goods or taxable services. A business can be perfectly profitable and well within its year-end numbers, yet already be liable to register because the last 12 months, counted month by month, have passed the limit.

If you register late, you may owe tax on sales you never charged to customers. If you register unnecessarily, you take on invoicing, bimonthly returns and record keeping you did not need. This guide sets out the thresholds Customs publishes, how the 12-month test works, and how to build a simple monthly check into your accounts.

The thresholds Customs publishes

Sales tax (manufacturers)

The Customs registering business page says a manufacturer of taxable goods must register when the sales value of taxable goods exceeds RM500,000 for a 12-month period. The same RM500,000 level applies to sub-contract work on taxable goods. Manufacturers of non-taxable goods are not eligible to register. The sales tax FAQ also lists certain manufacturing activities, such as tailoring, jewellery, optical work and engraving, as exempt from registration whatever the turnover.

Service tax (by group)

Service tax thresholds are set per group of services. The table below is taken from the registering business page.

The page’s table did not display a figure for every row when we read it, which is why several rows above say “confirm”. That is not a reason to assume zero. It means you should read your exact service line on the Customs page or ask Customs before relying on the table.

Services added in 2025

Customs’ FAQ on the expansion of service tax scope 2025 covers private healthcare, construction work, private education, rental or leasing, financial services and beauty treatment, effective from 1 July 2025 for the groups where the page states a date. The thresholds shown on that page were:

Secondary sources report that the rental, leasing and financial services threshold was raised to RM1 million. We could not confirm that on the official FAQ page, which still shows RM500,000, so treat rental, leasing and financial services as “confirm with Customs” until you have checked the current policy paper on the Service Tax Policy page.

How the 12-month test works

Customs describes two ways to measure the value:

• Historical method: the month in question plus the 11 months before it.
• Future method: the month in question plus the 11 months that follow it.

If either calculation exceeds the threshold for your category, you are liable to register. In practice the historical method is the one a growing business can run from its ledger every month. The future method is for planned changes, for example when you have signed a large contract that will push the next 12 months over the line.

Two points are easy to miss. First, the value that counts is the value of taxable goods or taxable services, not total company revenue. Exempt or non-taxable income does not count towards the threshold. Second, the test is per category. If a business has a taxable service line and a separate manufacturing line, each is measured against its own threshold.

A worked example (illustrative)

A cafe in Petaling Jaya serves food and drink only. The food and beverage threshold on the Customs page is RM1,500,000, which is an average of RM125,000 a month (RM1,500,000 divided by 12).

The cafe passes the line at month 15. The owner would have seen the trend from month 13 and started preparing, instead of finding out when the annual accounts were drawn up. These numbers are invented for the arithmetic only; your own ledger decides.

A monthly check you can copy

1. Export taxable sales or service income for the last 12 months from your accounting system, split by month and by service category.
2. Strip out income that is not taxable (for example exempt or out-of-scope items) and note why.
3. Add up the rolling 12 months ending this month and compare with the threshold for each category.
4. Run the future method if you know of contracts, price rises or new outlets that will lift the next 12 months.
5. Record the result and the date in a one-line file note. If you are above 80 percent of the threshold, mark the month you expect to cross.
6. When you cross, start the registration application straight away through the MySST portal and keep the evidence of the date.

If you use outsourced bookkeeping, ask for the rolling total to be a standing line in the monthly management pack. Our guide on the documents to send your accountant each month explains what a clean monthly feed looks like.

How to register once you cross

Customs’ registering business page lists the online entry points on the MySST portal: new registration for sales tax and service tax, a registration status inquiry, and retrieval of a saved request. The page does not give a general number of days to apply for businesses that cross the threshold after the original 2018 start. It does say that those who qualified but were not registered at the 2018 start had to apply within 30 days of the commencement date. For a current crossing, do not wait for a deadline you have not confirmed: apply as soon as the rolling total passes the limit, and ask Customs or an adviser what date your liability starts from.

Branch registration is allowed, and group registration is not applicable, according to the same page. Each legal entity therefore tests and registers on its own.

Voluntary registration

Customs allows a business below the threshold to register by application, subject to conditions set by the Director General. For sales tax, voluntary registration is available only to manufacturers of taxable goods. Some register voluntarily because a customer expects an SST number. Remember what you are signing up for: you must then charge the tax, file the return every period even when sales are nil, and keep records for seven years. Voluntary registration is a commitment, not a badge.

Cancelling registration when sales fall

Customs’ service tax FAQ states that if your annual taxable service sales fall below the threshold, you may apply in writing to the Customs Department to cancel your registration, and cancellation needs approval. Until it is approved, keep filing. The filing page adds that a final SST-02 return must be submitted not later than 30 days after cessation of the taxable activity.

What this means for different businesses

• Sdn Bhd: SST registration is per legal entity. Group registration is not available, so a holding company and its operating subsidiaries are tested separately. Reflect SST in your pricing and in the contract wording with corporate customers.
• Sole proprietor or partnership: the legal form makes no difference. A freelance consultant or small restaurant is tested on the same basis as a company in the same group.
• Foreign-owned company: a Malaysian subsidiary providing a taxable service in Malaysia is tested like any other. Separately, Customs’ understanding SST page notes that service tax also applies to imported taxable services, with a separate non-registrant route on MySST. Ask us if you buy services from overseas.

Common threshold mistakes

• Using the financial year instead of a rolling 12-month window.
• Counting total revenue instead of the value of taxable goods or services.
• Ignoring the 2025 expansion groups, such as rental, construction or healthcare, because “SST does not apply to us”.
• Testing once and never again.
• Assuming a blank row in a threshold table means no threshold.
• Registering voluntarily and then forgetting nil returns.

How Axecta helps

Axecta’s tax team runs the rolling test from your ledger, reads the Customs category lists against what you actually sell, files the MySST application when you cross and sets the first bimonthly return dates in your calendar. If you also face e-invoicing, we line up the two so that your e-invoice position and your SST invoices do not contradict each other. See our SST registration and returns service.

Next steps

1. Pull your last 12 months of taxable sales by category this week.
2. Compare each with the threshold on the Customs page, noting any row you could not confirm.
3. Set a monthly reminder to roll the total forward, and add SST dates to your compliance calendar.
4. Read who must register for SST if you are unsure whether your activity is listed, and how the two taxes differ.
5. If you are within reach of a threshold, ask for a registration check.
