Built for the people who actually file
For consultants
Validate and fix client files without cleaning every spreadsheet by hand. Save sessions, duplicate for next year, and keep filing history across clients.
For multi-establishment employers
One file with multiple locations means more ways to fail formatting. Catch cross-field issues and missing values across every establishment before uploading.
For spreadsheet-based teams
Keep your spreadsheet. ITA Ready validates the export, fixes safe formatting problems, and gives you a corrected file to upload.
