The 5 Most Costly XBRL Tagging Errors in SEC and ESEF Filings

XBRL tagging is one of the most failure-prone stages of the SEC and ESEF filing process. While financial statements may be technically correct, execution issues in structured data often surface late in the cycle, when timelines are tight and tolerance for error is low.

Manual tagging, evolving taxonomies, credential dependencies, and compressed review windows create conditions where small technical mistakes lead to validation failures, delayed submissions, and regulator follow-ups. These issues are operational in nature, but their impact is regulatory and reputational.

This infographic highlights the five XBRL tagging errors that most commonly derail SEC and ESEF filings, along with why they persist and where teams lose time and take on unnecessary risk.

Inside, you’ll learn:

• The most frequent XBRL tagging errors regulators flag across SEC and ESEF filings.
• Why execution issues such as credentials, taxonomy alignment, calculations, and flags cause validation failures.
• How automated, parallel XBRL execution reduces rework, filing delays, and submission risk.
