Form-specific IRIS troubleshooting

IRIS CSV error guides for every supported form.

Choose the information return you are preparing. Each guide uses that form's bundled CSV layout, exact column count, and form-specific fields to help diagnose header, row-width, identifier, date, amount, code, and spreadsheet-export problems.

35 form-specific guides

Find the exact form you are troubleshooting.

Do not troubleshoot a 1099-NEC file with a generic 1099 checklist. Open the page that matches the actual CSV layout you are uploading.
