On 12 November 2025, the Financial Administration of Slovenia (FURS) published an updated list of tax calculations and filings that require a mandatory e-invoice.
This update is part of the ongoing digitalisation of tax reporting and affects how accounting departments and businesses issue and submit tax-related documents.
Incorrect e-invoice formatting can result in:
-
rejected filings,
-
delays in tax submission,
-
additional administrative work,
-
compliance risks for companies.
🔍 Key changes:
-
The list of document types requiring a mandatory electronic invoice has been expanded.
-
Several new types of tax calculations now fall under the e-invoice obligation.
-
Accounting systems and software solutions must be updated accordingly.
-
Standardised formats improve transparency and make automation easier.
How this impacts companies:
-
Older or outdated software may not meet the new e-invoice requirements.
-
Incorrectly formatted e-invoices can cause delays in processing and affect tax deadlines.
-
Companies must ensure all accounting workflows are aligned with the updated FURS rules.
