SST Audit by Customs (RMCD): What to Expect and How to Respond

The Sales and Service Tax regime is administered by the Royal Malaysian Customs Department (RMCD) — and with the expanded scope of service tax pulling many businesses into the net for the first time, SST audits have become a fact of life for Malaysian SMEs. This article explains what an SST audit involves, what the officers look for, and what to do if the audit ends with a Bill of Demand.

Who gets audited?

Any SST-registered business can be selected — manufacturers under the Sales Tax Act 2018 and taxable service providers under the Service Tax Act 2018. In practice, audits are also triggered by:

• late or amended SST-02 returns;
• claims for exemptions or facilities;
• mismatches between your SST declarations and your income tax filings;
• industry sweeps after the scope of service tax was expanded; and
• businesses that arguably crossed the registration threshold but never registered.

That last category matters: you can be audited even if you were never registered, on the basis that you should have been.

What the officers examine

RMCD officers will typically ask for your SST-02 returns, tax invoices, credit and debit notes, general ledger, contracts with customers, and the documents behind any exemption you claimed. The law requires SST records to be kept for seven years — and the burden of supporting your position sits with you, not with Customs.

Common findings in SST audits include:

1. taxable services classified as non-taxable;
2. under-declared taxable turnover;
3. registration threshold crossed without registering;
4. exemptions or intra-group reliefs claimed without meeting the conditions; and
5. imported taxable services with no reverse-charge accounting.

The Bill of Demand

If the audit concludes against you, RMCD issues a Bill of Demand (BOD) for the tax found short, usually with penalties. Three things to understand:

It is not a final verdict. A BOD is Customs’ position — it can be reviewed, negotiated and challenged.

Silence is expensive. Ignoring a BOD leads to enforcement — and the amount does not shrink while you wait.

The clock is short. Challenges to Customs’ decisions run on strict windows — generally 30 days to apply for review or to appeal to the Customs Appeal Tribunal. By the time a BOD has been sitting in a drawer for two months, most of the good options are gone.

If you find the mistake first

If you discover an SST error before Customs does — a missed registration, an under-declaration — coming forward voluntarily, in the right way and at the right time, generally attracts significantly better treatment than being caught in an audit. The order of steps matters: get advice before you write to Customs, not after.

How a tax lawyer helps

An SST audit is a legal process, not just an accounting exercise. Classification of services, the conditions of exemptions, and the validity of a Bill of Demand are questions of law. We deal with the officers on your behalf, respond to audit findings, apply for review, and — where it counts — appeal to the Customs Appeal Tribunal and the courts.

If you have received an audit letter or a Bill of Demand, do not sit on it. Speak to a tax lawyer while every door is still open.
