Massachusetts 1099-HC CSV Intake Checker
Check the columns and obvious missing data in a local source worksheet for Massachusetts 1099-HC coverage reporting. This checker does not transmit or store data, generate DOR XML, check identity, or confirm MCC eligibility.
Private-by-design: Your selected file is processed inside this browser tab. Nothing is uploaded to 1099ERICH. Because subscriber data can be sensitive, use a secure computer and never email raw subscriber or medical records.
1. Download the starter intake header
Use Y or N for each month. A blank file is supplied; import data only after you map it accurately from your systems. Month flags are source fields and do not determine MCC for you.
2. Check a local CSV
CSV only. For Excel files, save as CSV first. This is a proprietary preparation layout, not an official Massachusetts import format.

Even a clean intake file is not an XML filing file. Validate XML against the latest Massachusetts DOR XSD and verify facts before submission.
