To generate an ESF for a non-resident for a past period, you first need to create a VAT invoice for the non-resident in 1C, and then generate the ESF itself based on it.
Procedure
1. Create the "Invoice" document with VAT accrual for the non-resident — for the period to which the transaction relates (1st quarter).
2. Based on this document, generate the ESF for the non-resident — use the "create based on" command directly from the invoice so that the data is pulled in automatically and you don't have to fill everything in manually.
3. Check the details in the generated ESF (amount, period, non-resident counterparty data) and send the document in the usual manner.
This method allows you to correctly process the transaction with the exact period to which it actually relates, even if you are generating the invoice and ESF now, rather than at the time the transaction was performed.
Frequently asked questions
Can I create an ESF right away, without a VAT invoice?
For transactions with a non-resident, the correct approach is to first issue a VAT invoice for the non-resident, and then generate the ESF based on it, so that the data is consistent between the documents.
What if the period is already closed?
You still create the invoice and ESF with a date relating to the required period (1st quarter) — the system allows this kind of backdating for this type of transaction.
