Online filing error 3304

Full error message

Error type: business

Error number: 3001

The submission of this document has failed due to departmental specific business logic in the Body tag.

Type: Business

Number: 3304

Location: Known facts check

Original return already received for this period.

Reason for error

HMRC records show that they have already received a company tax return for this period. You cannot send two returns for the same period unless the second return is marked as an amendment.

Solution

If you are attempting to file an amended return, then go to Computation Preview > Generate Submission Files and select Amended Return.

If HMRC records are incorrect and a return for this period has not previously been filed, then contact HMRC Online Service Helpdesk on 0845 60 55 999.

This error message can also arise if you attempt to re-submit the return when a submission is already in progress.
