Inline XBRL Tagging Rules and SEC Filing: Key Insights

Inline XBRL (iXBRL) has become the standard for filing financial reports with the U.S. Securities and Exchange Commission (SEC). This format combines the flexibility of HTML for human readability with XBRL’s machine-readable data structure. Understanding the Inline XBRL tagging rules is essential for compliance, accuracy, and efficiency in SEC filings.

Key Inline XBRL Tagging Rules for SEC Filings

The SEC requires public companies to file their financial data using Inline XBRL, adhering to specific tagging rules:

1. Correct Tagging of Financial Data

   Each financial statement element must be tagged with the appropriate XBRL tag from the US GAAP Financial Reporting Taxonomy. Tags identify specific data, such as revenue, expenses, assets, liabilities, and equity. Correct tagging ensures that the data can be accurately extracted and analyzed.

2. Use of the US GAAP Taxonomy

   For U.S.-based public companies, the SEC mandates using the US GAAP Financial Reporting Taxonomy. This taxonomy is updated periodically, and companies must use the latest version to remain compliant. Using the correct taxonomy ensures that financial statements are consistently structured and comparable.

3. Embedding Tags in HTML Format

   iXBRL filings must include the XBRL tags embedded within the HTML content of the financial reports. The tags are invisible to readers but can be extracted by machines for data processing and analysis.

4. Consistency in Tagging Across Reporting Periods

   To maintain consistency, companies must use the same tags and taxonomy elements across different reporting periods. This allows for accurate year-over-year comparisons of financial data and ensures compliance with SEC regulations.

5. Proper Use of Custom Tags

   In some cases, companies may need to use custom tags for items not covered by the standard taxonomy. However, the use of custom tags should be limited to avoid confusion and ensure the data’s clarity and accuracy.

Benefits of Inline XBRL for SEC Filings
