Submission Errors returned by HMRC during online filing

HMRC acknowledge receipt of your online filing and the software displays a green tick with message - Submission process has successfully completed...' - job done.

The speed of submission to HMRC and responses received from HMRC is determined by many factors - level of tax return data, size of accounts, computations or any supporting PDF you have attached with the returns, your internet speed, HMRC system workload, etc. The software does not control this speed. The most important result is a successful Live submission.

The software performs data validations checks based on HMRC specifications for data entered within the software, you will be prompted to correct any anomaly. The software cannot check the validity of data within any documents attached, for instance 3 rd party generated accounts and computations iXBRL files and any supporting PDF files.

When submitting returns online to HMRC through the software, HMRC's system will perform various data validation check on the data you are submitting. In case it encounters any issue with the data a response is sent back to the software and Andica software simply displays messages returned by HMRC. The software does not control any data entered, any attachments or data within those attachments or messages relayed back by HMRC.
