Hi there, @mcmurren. Rejections are caused by missing recipient data or formatting issues within the T4A boxes.
To help me pinpoint exactly what went wrong, could you provide the specific error code or message?
In the meantime, ensure all names and addresses are free of special characters (like # or &), double-check for missing SINs or Business Numbers, and verify that all amounts are positive values assigned to the correct box numbers.
Keep us posted for any additional information or concerns.
