The Ministry of Revenue & Duties explains
The General Directorate of the Ministry of Revenue & Duties of Ukraine explains there are no restrictions on a number of times the taxpayers can file reports a day, if it is made electronically. Thus, if a taxpayer has not received the first receipt after submitting the documents, the latter can send the reports again on the same day.
Moreover, the taxpayer is entitled to repeatedly send tax returns, payment records in case errors or corrections have been made until the reporting deadlines, putting down "Reporting, New" to indicate the type of a document
It is worth noting that if a taxpayer has sent a few copies of one reporting document to the oversight authority (in case the data has been corrected, but the first receipt has not been received, etc.), the electronic document received the latest is regarded to be an original, on condition that its registration number has been entered into the database, with sending the second receipt to the taxpayer.
