EDGAR Formatting Guidelines

Everything You Need to Know

Accepted File Types and EDGAR Format Standards

When preparing your EDGAR submission, the SEC expects documents to follow a strict set of technical specifications. The main body of your filing must be in HTML or ASCII format. PDFs are only permitted for exhibits, not for the primary content.

You should also adhere to the following formatting standards:

  • Use common fonts like Times New Roman or Arial, typically in size 10.
  • File sizes must not exceed 10MB per file and 200MB per submission.
  • Embedded scripts (e.g., JavaScript), style sheets, or hyperlinks are prohibited.
  • Images should be clear and easy to understand in the document.
  • Financial tables should be neatly pasted in from Excel or created directly in the Word document. Please ensure tables use a table structure, rather than separating text elements with tabs or spaces. Your tables should be in a final format and design that you would like them to appear in. We can add row shading separately. If you need to send Excel files separately as well, please do.

These limitations ensure EDGAR’s system can read and store your files properly.

Structuring the Document with Required Tags

Each EDGAR filing must begin with standardized tags that clearly define the form type, sequence, filename, and body text. These tags tell the SEC’s system how to interpret your file.

A typical section will look something like this:

Code

<DOCUMENT>
<TYPE>10-K
<SEQUENCE>1
<FILENAME>form10k.htm
<TEXT>
<html>…</html>
</TEXT>
</DOCUMENT>
  

Beyond the tags, filings must include a cover page, accurate page numbers, and properly formatted headings and subheadings. Signature blocks are required at the end of applicable forms to certify the content.

The SEC permits basic formatting to aid readability, but everything must be rendered in clean HTML. Financial tables must use <TABLE> tags with rows and columns defined—images of tables are not allowed.

If charts or visual elements are essential, they can be embedded in the HTML file easily when we Edgarize the document for you. They will also be attached as exhibits in the submission file.

Exhibits and Attachments

All supporting materials that are not part of the main form, such as Power of Attorney documents, signatures, or XBRL attachments, must be submitted as exhibits. Each exhibit should be correctly named and tagged, and you’ll need to include an exhibit index within your filing. At Southridge, we handle these technical details for you.

For example:

  • XBRL files use codes like EX-101.
  • Signature pages might use EX-24.
  • Other supplemental materials could use EX-99.1, EX-99.2, etc.

Each exhibit must also follow file-naming conventions and cannot exceed size limits.

Common Mistakes to Avoid

Even experienced filers sometimes overlook small but critical requirements. The most frequent formatting mistakes include:

Submitting the primary document as a PDF instead of HTML

Using incorrect or inconsistent HTML tags

Forgetting to include the cover page or signatures

Including non-standard fonts or special characters that EDGAR can’t process

Skipping validation steps before submission

If all recovery methods fail, the SEC requires submission of a notarized Form ID to reestablish access.
