If you've landed here from outside Malaysia, you're probably comparing XBRL regimes across borders — for a multinational group, an international audit, or simply out of interest in how the standard is applied differently around the world. This guide is written for that reader.
Why compare at all
XBRL itself is a single global standard maintained by XBRL International. What differs country to country is which regulator adopted it, which companies must use it, what the local taxonomy contains, and what software is available (free or paid) to prepare a filing. Understanding those differences matters if you're managing filings in more than one country, or simply trying to gauge how demanding Malaysia's requirement is relative to peers.
The four regimes side by side
| Jurisdiction | Regulator | Format | Who must file | Prep tool |
|---|---|---|---|---|
| United States | SEC (via EDGAR) | Inline XBRL (iXBRL), since 2018 | Public companies only | Commercial software / filing agents |
| United Kingdom | Companies House | iXBRL | All UK-registered companies (mandatory software-only filing confirmed from April 2028) | Commercial software only — no free government tool |
| Singapore | ACRA (via BizFinx) | XBRL — Full or Simplified template by size | Most companies; dormant and solvent exempt private companies may be exempt | BizFinx Preparation Tool (free) |
| Malaysia | SSM (via MBRS) | XBRL, tagged against SSMxT | Most companies; EA1/EA2/EA3 exemptions available | mTool (free) |
United States: SEC / EDGAR
The US was an early mover: the SEC mandated XBRL for public companies starting in 2009, phased in by company size, and moved to Inline XBRL (iXBRL) — a format that embeds machine-readable tags directly inside a human-readable HTML filing — in 2018. Filings go through EDGAR (Electronic Data Gathering, Analysis, and Retrieval), tagged against the US-GAAP taxonomy (or IFRS for certain foreign private issuers). Critically, this only applies to public companies filing with the SEC; private US companies have no equivalent XBRL obligation.
United Kingdom: Companies House
The UK regime is the most sweeping of the four in scope. Under reforms confirmed by Companies House following the Economic Crime and Corporate Transparency Act 2023, all UK-registered companies — not just public ones, and regardless of size, including dormant companies — will be required to file accounts in iXBRL format using commercial software, with the existing free web and paper filing routes closing. This is confirmed to take effect from April 2028. Unlike Malaysia or Singapore, the UK does not provide a free government-issued preparation tool; companies must obtain commercial software or use an accountant/agent who has it.
Historically, very small UK companies could file simple accounts through free government services. Those routes are being retired as part of the move to mandatory software-based iXBRL filing — a materially different cost picture from Malaysia's free mTool.
Singapore: ACRA / BizFinx
Singapore adopted XBRL filing for its Accounting and Corporate Regulatory Authority (ACRA) in 2007, making it one of the earlier adopters in the region. Most Singapore-incorporated companies filing financial statements must do so in XBRL, using ACRA's free BizFinx Preparation Tool, submitted via the BizFile+ portal alongside the Annual Return. Singapore uses a size-based format split: companies below specific revenue and asset thresholds can use a reduced "Simplified XBRL" template, while larger or more complex companies file the full template. Dormant companies and certain solvent exempt private companies can qualify for a full exemption from filing financial statements at all.
Malaysia: SSM / MBRS
Malaysia's system, covered throughout the rest of this site, sits structurally between Singapore's and the UK's: like Singapore, SSM provides a free preparation tool (mTool) and a size/exemption-based simplified route (the EA2 "Key Financial Indicators" exemption); like the UK's incoming regime, MBRS applies broadly across company types under the Companies Act 2016, not only to public/listed companies.

What's the same everywhere
- The core concept: every regime tags individual financial figures against a taxonomy — a fixed dictionary of approved labels — so a computer can read a filing without a human retyping the numbers.
- Validation before submission: every jurisdiction's preparation tool runs checks before a filing can go through, and error handling (missing tags, mismatched totals) is a universal pain point regardless of country.
- A phased, size-aware rollout: every regime introduced some form of simplified or delayed treatment for smaller entities rather than demanding full compliance from every company on day one.
What's genuinely different
- Scope: the US applies XBRL only to public companies; the UK, Singapore, and Malaysia all apply it much more broadly, including to small and dormant companies.
- Cost of tooling: Singapore and Malaysia provide free preparation software; the UK's incoming regime requires companies to buy commercial software, with no free government alternative.
- Maturity: Singapore (2007) and the US (2009) have over 15 years of XBRL filing history; Malaysia's MBRS (2018, overhauled as MBRS 2.0 from 2024) and the UK's incoming mandate (2028) are comparatively newer.
