On July 31, 2025, the SEC made the Inline XBRL fee exhibit (EX-FILING FEES) mandatory for all fee-bearing submissions. Your familiar fee table stays, but it now must be mirrored in structured, machine-readable form. EDGAR validates the exhibit, so details like data types, currency, and identifiers must be exact.
This applies to operating companies and to certain investment companies filing on Forms N-2 and N-14. If you maintain a solid fee memo and run a brief pre-validation loop, the transition is straightforward and low risk.
What Changed and Why It Matters
Every fee-bearing filing must include an Inline XBRL exhibit titled EX-FILING FEES. EDGAR uses it to validate your fee facts against strict field rules. If a field expects an integer, a decimal will fail. If a unit is USD in your narrative, the tag must also be USD.
Specifically, EDGAR checks that:
- Share counts are integers, not decimals.
- Monetary amounts use the correct currency unit (typically USD) and scale.
- Rule selections (for example 457(c), 457(o), 457(r)) align with the transaction.
- 457(p) offsets reference a specific prior file number, with a clear remaining balance.
- For N-2 and N-14, series and class identifiers match exactly between the body text and the exhibit.
The aim is consistency and comparability, with fewer last-minute rejections. The SEC’s EDGAR Filing Fee Interface Courtesy Guide and the EDGAR Filing Fees hub provide exact field definitions and validation behavior.

How the EX-FILING FEES Exhibit Fits Your Filing Process
Treat the exhibit as an extension of your fee memo. The memo documents the rule basis, fee rate, aggregate offering amount or price, and any 457(p) offsets with prior file numbers and balances. The exhibit turns those same facts into tagged data that EDGAR can validate.
A practical flow looks like this. Draft the memo and lock identifiers early, especially security titles and, for funds, series and class IDs. Map each figure from the memo to a specific tag with the right unit, currency, and data type. Decide on scale (units or thousands) once and apply it consistently. Run pre-validation, fix warnings, and re-run until clean. Then ensure the narrative fee table and the tagged exhibit tell the same story.
- EDGAR Filing Fee Interface showing integer-only fields for share counts (illustrate 1 vs 1.00).
- Tag mapping sheet linking memo figures to iXBRL tags with units and data types.
The following are examples of how these XBRL tagging attributes are presented in the filing when the linked amount is expanded:
- Maximum Aggregate Offering Price:
- Fee Rate:
- Net Fee Due:
- EDGAR pre-validation results screen highlighting a currency or rule-basis warning and its fix.
Two quick examples
- An overnight S-3 takedown passed on the first attempt after pre-validation flagged a share count entered as 1.00 and an outdated 457(p) balance. Ten minutes of fixes preserved the pricing window.
- A fund’s N-14 reorganization was rejected due to a minor series name variance between the body and the exhibit. Standardizing identifiers from a single source of truth led to fast acceptance on refile.
Error prevention table
Use this quick reference to spot and prevent the most common EX-FILING FEES validation errors in EDGAR:
| Error | What EDGAR sees | How to prevent |
| Integers entered as decimals for share counts | 1.00 shares instead of 1 | Tag counts as integers, verify units and data types during mapping |
| Wrong rule basis in tags | 457(o) selected when the memo uses 457(c) | Lock the rule basis in the memo first and tag to match |
| Currency mismatch | Monetary fact tagged in a non-USD unit with a USD narrative | Set the unit to USD, and confirm units on every monetary tag |
| Incomplete 457(p) reference | An offset with no prior file number or balance trail | Maintain an offset ledger and cite the exact source |
| Series or class mismatch on N-2/N-14 | Identifier strings that differ between the body and exhibit | Freeze identifiers from a single source of truth before tagging |
| Inconsistent scaling | Narrative in thousands, tags in units, or the reverse | Choose a scale once and apply it consistently in both places |
Final pointers
Keep the memo, mapping, and validation logs as an archive for takedowns and amendments. Align rule basis, units, and identifiers once, then carry those decisions through your tags. A short pre-validation loop turns filing day into a routine, not a scramble.
