What is the ACRA taxonomy
The ACRA taxonomy is a dictionary for XBRL language. It is based on disclosure requirements for financial statements (FS) under Singapore's accounting standards and Companies Act 1967.
Key features of the ACRA taxonomy:
Closed taxonomy: You cannot add or define your own company-specific concepts or create custom relationships between concepts. This ensures all companies report data in a comparable way.
Some flexibility allowed: You can customise labels for your company and reorder concepts for presentation.
Which version to use

How to map financial statement items
Mapping means matching the line items in your annual general meeting (AGM) FS to the relevant concepts in the ACRA Taxonomy. For example, the “amount of fixed assets” in FS maps to “Property, Plant and Equipment” in the taxonomy.
All tabs in the BizFinx preparation tool template must be completed. Fields should be left blank if the information requested in the template is not disclosed in the AGM FS.
Who should do the mapping
You should involve an officer who is most familiar with your FS to do the mapping. To ensure accuracy, your company should review the mapping before submitting it to ACRA.
Types of mapping
There are four ways to map information from your FS to the ACRA Taxonomy:
Ways to map in the ACRA taxonomy
Type | Example |
|---|---|
One-to-one mapping: A single item maps directly to one concept in the taxonomy. | "Turnover" in your FS maps directly to "Revenue" in the taxonomy. |
Many-to-one mapping: Multiple line items are combined and mapped to a single concept in the taxonomy. | If you have "Stocks" and "Inventories and work in progress" as separate line items:
Note: You need to create a footnote to explain the aggregation. Use the footnote mechanism in the XBRL format. |
One-to-many mapping: A single line item is broken down and mapped to separate concepts in the taxonomy. | If you have "Intangibles" as a line item, break it down into:
Then, map to these two separate concepts in the taxonomy. Best-fit principle: If there is no breakdown available or no simple equivalent in the taxonomy, map the full amount to the closest matching concept. For example, the full amount of "Equipment" could be mapped to "Machinery and other equipment" or "Communications and network equipment". This depends on which concept is the best fit. Finding the best fit requires accounting knowledge and judgement. |
Mapping to "Others": If a line item has no relation to any concept in the taxonomy (even under best-fit principles), classify it under "Others". Note: You must include a footnote to explain and break down anything classified under "Others". | - |
