When filing ACA information returns, you may encounter the TPE1101 error in the IRS AIR (Affordable Care Act Information Returns) system. This message means the XML file is not well formed, which prevents the IRS from processing it. In other words, the file has a structural or syntax problem that must be fixed before resubmission.
Common Causes of TPE1101
1. Structural Issues
First, the error often results from:
-
Missing required XML elements.
-
Mismatched or unclosed XML tags.
-
Improperly nested elements.
2. Syntax Errors
Next, the XML may include:
-
Illegal characters such as
-,#,&,<or>. -
Incorrect encoding (for example, not using UTF-8).
-
Extra or missing quotation marks around attribute values.
3. Invalid Data
In addition, problems may arise when:
-
Data violates XML rules (e.g., unescaped characters).
-
Required fields contain null or empty values.
4. File Corruption
Finally, the error can occur if the file becomes corrupted during creation, editing, or transmission.
How to Fix TPE1101
To resolve this error:
-
Validate your XML against the IRS schema.
-
Correct any missing or misplaced tags.
-
Ensure the file is saved in UTF-8 format.
