What the checker does
- Header: reports missing, extra or reordered columns compared with the 5498-SA template.
- Safe fixes: trims stray spaces, writes amounts as plain numbers, leaves $0 cells empty, fills empty Y/N boxes with N, adds dashes to TINs from the TIN type, restores ZIP leading zeros, converts state names to codes and rewrites dates.
- Errors to fix yourself: required columns left empty, values over the length limit, codes that are not in the allowed list, invalid TINs, ZIP codes and dates.
- Split: writes files of up to 250 records and under 100KB, keeping your header row.
Date columns: the IRS guidelines ask for MM/DD/YYYY but also say "Max 8 characters, Digits only". The checker accepts both MM/DD/YYYY and MMDDYYYY. If the portal rejects one, try the other.
For 1099-NEC and 1099-MISC, the main IRIS CSV tool goes further: it builds the template from QuickBooks, Excel or FIRE files.
