If you have been told your company needs to "file in MBRS" or "submit XBRL to SSM," this guide explains what that sentence actually means, without assuming you already know the acronyms.
Where MBRS came from
Before 2018, Malaysian companies filed their annual returns and financial statements with the Companies Commission of Malaysia — known by its Malay initialism, SSM (Suruhanjaya Syarikat Malaysia) — largely on paper or as static digital documents such as scanned PDFs. SSM introduced the Malaysian Business Reporting System, or MBRS, as a phased replacement for that process, with the rollout beginning in November 2018 and key filing types becoming compulsory nationwide from March 2019.
MBRS did not just move paperwork online. It changed the format the data is submitted in, from a static document a human reads, to structured, machine-readable data a computer can process, search, and compare automatically. That underlying format is called XBRL, which has its own dedicated guide linked below.
What MBRS actually submits
MBRS is the platform; the things you submit through it fall into three categories:
- Annual Returns (AR) — the yearly snapshot of a company's particulars: directors, shareholders, registered office, and share capital structure, required under the Companies Act 2016.
- Financial Statements (FS) — the audited or unaudited accounts a company is required to lodge, now prepared and tagged in XBRL format rather than submitted as a plain PDF.
- Exemption Applications (EA) — requests for specific relief from parts of the standard filing requirement, such as aligning a foreign subsidiary's financial year or applying to file only Key Financial Indicators instead of a full XBRL statement. See our audit exemption guide for the detail on EA1, EA2, and EA3.
The three working parts of MBRS
Once you look past the acronym, MBRS is really three separate tools working together:
| Component | What it is | What you use it for |
|---|---|---|
| SSMxT SSM Taxonomy | A standardised dictionary of reporting "elements" — the approved labels for every line item a financial statement or annual return can contain. | Defines what each piece of data is called when it is tagged. |
| mTool MBRS Preparation Tool | A free, downloadable Excel-based application provided by SSM. | Where you actually enter data and tag it against the taxonomy before submission. |
| mPortal MBRS Portal | The online submission platform, reached through the SSM4U/MyCoID login system. | Where the completed, validated file is uploaded, digitally signed, and lodged. |
Our dedicated guide to SSMxT, mTool, and mPortal walks through each of these in more depth, including where to download mTool and how the digital signature step works — or if you haven't registered for portal access yet, see registering for mPortal first.

Who has to use it
In broad terms, MBRS applies to companies registered with SSM under the Companies Act 2016 — both public and private companies incorporated in Malaysia, as well as foreign companies registered to operate in the country (see our guide for foreign companies). Historically, certain financial institutions regulated separately by Bank Negara Malaysia sat outside the mandate; that exemption has since narrowed under MBRS 2.0 (see below). Because eligibility, exemptions, and phase-in dates depend on your specific company type and financial year, this page is a starting point, not a determination — confirm your company's exact obligation on the official SSM website or with your company secretary.
MBRS is the submission platform; XBRL is the data format it runs on; SSMxT, mTool, and mPortal are the three pieces you actually interact with to prepare and file.
MBRS vs MBRS 2.0
If you have seen both "MBRS" and "MBRS 2.0" mentioned and are not sure whether they are the same thing: they are the same platform at different stages. MBRS 2.0 is an enhanced version SSM began rolling out from December 2024, built around updated financial reporting standards and an expanded taxonomy, and it became fully mandatory for financial statement filings from 1 June 2025. If your information is from before that transition, some details — particularly around which entities are covered — may be out of date. See our MBRS 2.0 guide for what specifically changed.
Where to go next
If MBRS is new to you, the most useful next read is usually What Is XBRL? — understanding the underlying data format makes every other MBRS guide easier to follow. If you already know roughly what XBRL is and want to know what changed recently, jump to MBRS 2.0: What Changed.
