XBRL Challenges & How We Can Help

Challenge: XBRL Complex Standards

All filings submitted in XBRL format require both block and detail tagging of financial statements and footnotes. Each line item and value must be matched to a taxonomy tag, with proper context periods, precision, and metadata, including parenthetical data.

Solution: Our Accurate Services

Staying compliant with the SEC’s XBRL tagging requirements doesn’t have to be complex. At Colonial Filings, we provide accurate, fast, and fully compliant XBRL filing and iXBRL filing services to help public companies meet regulatory deadlines with confidence.

Why is XBRL Tagging Important?

XBRL tagging allows financial data to be machine-readable and easily analyzed by the EDGAR system, investors, and regulators.
By assigning XBRL tags to each component of a financial report, companies help ensure faster processing and increased transparency.

Under SEC Rule 405 of Regulation S-T,
filers must follow four levels of XBRL tagging for footnotes:

Level 1: Each footnote disclosure

Level 2: Each significant accounting policy

Level 3: Tables and schedules within each footnote

Level 4: Detailed numerical values in text and tables

Where possible, using structured tables instead of unstructured text improves XBRL mapping and reduces errors
