Hi,
I am currently trying to submit an MTD return. The settlement period for this entity is August-October 2020 but we are submitting now as the entity has ceased trading at the end of September.
However whenever I try to send the report I receive an error ;
Response Code : 403
Response Description : WebServiceError
What does code 403 mean? Is it not possible to submit a return before the end of the settlement period?
Thanks for any help
