5 Common Mistakes in ESEF Filings and Why They Keep Happening

Every CFO knows the story. The annual report is ready, the iXBRL tagging “looks fine,” and then the audit comments start rolling in. Hours before submission. ESEF filings (European Single Electronic Format) has been mandatory for listed companies since 2020, yet every year the same problems appear, even among teams that consider their process mature. 

Here are the five traps that keep finance leaders awake at night, and how to avoid them once and for all. 

1. Treating ESEF filings as a technical afterthought 

Many companies still see ESEF filings as a formatting exercise. Tag, validate, submit. 
Except it’s not. It’s now a key part of the audit trail, your report’s digital DNA. 
If tagging accuracy or taxonomy alignment fails, regulators notice. And so do investors. 

How to avoid it?  Integrate tagging early into your close cycle, not at the end of it. ESEF is a reporting process, not a last-minute export. 

2. Copying last year’s tags without validation 

It sounds efficient… until taxonomy changes hit. ESMA updates the ESEF taxonomy every year to reflect new IFRS standards, which means last year’s tags might already be obsolete. Validate against the latest ESMA taxonomy before numbers are final. It saves weeks later. 

3. Relying on spreadsheets to manage tagging 

If your ESEF process still lives in Excel, you’re one error away from a regulatory headache. 
Manual mapping, broken links, and lost version control are the usual suspects. 

It’s time to witch to a controlled, automated workflow that tracks every change, and builds audit-readiness in by design. 

4. Ignoring multilingual consistency 

For EU companies publishing reports in multiple languages, tag mismatches are a hidden liability. Regulators compare them. Auditors flag them. 

We can help you synchronize tags across all language versions from the start. It’s not a detail, it’s compliance. 

5. Underestimating the audit loop 

The number one reason filings go late? Endless auditor revisions. 
Auditors need proof that every tag reflects IFRS meaning. If they don’t get it, you get another round of questions. 

Bring auditors into the process early, and work with a partner who manages that collaboration directly.
