Font sizing has been optimized across all three VAT PDF forms to help prevent data from overlapping, improving readability, and ensuring information is displayed clearly for review and submission purposes.
Portugal VAT return Annex 40 and Annex 41 reporting
The reporting logic for Annex 40 and Annex 41 has been updated to support more accurate handling of credit notes.
Customers can now exclude certain credit notes from annex reporting when the credit note is issued in the same reporting period as the original invoice. This helps ensure that annex reporting is more accurate and aligned with reporting requirements.
important
Customers using imports should update their import mapping to include the
InvoiceType5
field and identify any credit notes that should be excluded. Romania:
VAT Return has been updated to improve reporting of historical VAT rates of 19%, 9%, and 5%. Transactions can now be reported in boxes 5, 5.1, 7, 7.1, 20, 20.1, 22, 22.1, and 31 for these rates.In addition, support has been introduced to report both invoices and credit notes relating to the historical VAT rates of 19%, 9%, and 5% in boxes 6, 8, 16, 21, 23, and 33. This enhancement improves the accuracy and completeness of VAT reporting and helps ensure historical-rate transactions are reported consistently within the VAT return.SAF-T
Denmark SAF-T header report
A new Header Report is now available for customers using non-registered accounting systems in Denmark.
In line with Danish Tax Agency requirements effective January 1, 2027, non-registered accounting systems may continue to provide SAF-T version 1.0, which consists of a header file only.
This report enables customers to generate the required SAF-T information in accordance with the applicable reporting requirements for non-registered systems. By supporting the approved version 1.0 header file format, the update helps customers maintain compliance with Danish SAF-T obligations and meet their reporting requirements with confidence.
RO SAF-T Double Entry Accounting -Analysis Structure update
The appropriate markup has been added to prevent empty fields from being displayed in the output. This change allows our clients to manage their data with greater flexibility, as they are no longer required to provide optional-mandatory data that was previously treated by our software as hard mandatory.
Poland JPK_KR_PD Reporting Structure
An update has been implemented to improve the generation and reporting logic within the JPK_KR_PD file. The structure has been refined to ensure that journal entries, posting records, and counterparty information are generated at the appropriate level of detail and aligned correctly within the report.
In addition, we added the missing CelZlozenia (Reason for Submission) element to the XML output. The issue was caused by a platform-level database change affecting the report parameter configuration. The XML generation logic has been updated to ensure that CelZlozenia is correctly populated and included in the output, preventing validation errors related to the missing element.
SII
New Rejected status to prevent duplicate AEAT re-submissions.
Enhanced the handling of invoices rejected by AEAT to stop recurring duplicate errors on the
Submissions
screen. Previously, when an already-accepted invoice was re-submitted with the same Invoice ID and Communication Type A0, AEAT rejected it as a duplicate, and the daily scheduler continued to re-pick and re-submit it on every run, generating repeated error rows. With this enhancement, invoices rejected by AEAT are moved to a new "Rejected" status rather than reverting to "To Be Uploaded," so the scheduler no longer automatically re-submits them. The affected records remain visible on the Submissions
screen for more details.E-invoicing data enrichment for Poland JPK VAT reporting - KSeF Id
This enhancement extends how KSeF ID that is part of the invoice in Pagero is populated during Poland JPK VAT reporting. Previously, KSeF information was sourced solely from the imported source file. With this update, when KSeF ID is not available, system can automatically retrieve it from the e-invoicing application (ONESOURCE Pagero), provided a matching record is found. The retrieved KSeF information is displayed in the import detail view, which then included in the JPK VAT XML output, ensuring the required details are reported even when they are not supplied in the source file. If no matching KSeF information is available, the import process continues without interruption, allowing the data to be reviewed and updated as needed.
This enhancement supports more complete and compliant reporting, improves processing efficiency, and helps maintain consistency between the import detail view and the generated XML output.
note
The functionality is driven through a setting "Enable JPK KSeF ID Extraction from OneSource E-Invoicing".

Returns
Accurate Reason Code Reporting in the Hungary VAT Domestic Purchases List:
Hungary VAT reporting now uses Reason Code when grouping transactions on the Domestic Purchases List (M-Sheet). If a single invoice contains transactions with different reason codes, such as V and KÜL, each transaction is reported on a separate row, and its reason code is fully retained. Previously, transactions with matching key details could be combined into one row, allowing only one reason code to appear while the other was omitted.With this update, Reason Code is evaluated together with the existing transaction grouping details. Entries with the same invoice information but different reason codes remain separate, while transactions with the same reason code, or no reason code, continue to be combined as before.
This improvement increases the accuracy and completeness of Hungary VAT DSPL reporting by ensuring the indication of the difference arising from the advance is captured correctly for each transaction, supporting compliance with domestic purchases reporting requirements.
Imports
Reliable Line Type Assignment for Import Rules:
Import Line Type rules are now applied correctly when multiple rules are configured or when a combination of Include and Exclude data rules exists. Previously, such configurations could cause rules to be applied incorrectly, skipped, or assigned inconsistently, in some cases populating values on imported transactions that did not match the source file. With this update, Include and Exclude data rules are evaluated together as intended, ensuring line type assignments reflect the configured rules without conflict or misapplication. This improvement increases the accuracy, consistency, and reliability of import processing, giving greater confidence that imported data is assigned correctly.Reports
Accurate messaging for GL Reconciliation when GL data is missing
: Corrected the messaging on the GL Reconciliation report (Aggregated Mismatch in Amount) for cases where only a transactional file is uploaded and no corresponding GL file is present. Previously, the system misleadingly returned "Reconciled, no mismatches found," implying a successful reconciliation had occurred when in fact none had taken place due to the missing GL data. The system now displays "No GL data available for reconciliation," clearly indicating that reconciliation did not run because of the absent GL file. Additional columns on the UAE Refund Form report
Extended the UAE Refund Form report to further build on the earlier enhancement that split output by box number. The standard report now includes 4 additional columns: - Customs Declaration Number
- Ship to Customer Name
- Emirates
- Customs Authority
These columns better support UAE refund reporting requirements and provide a more complete view of the underlying data.
New Intrastat Transactional Adjustments report
Introduced a new Intrastat Transactional Adjustments report, available from the Reports section, bringing Intrastat reporting in line with the existing Transactional Adjustment report already available for VAT/ESL. This addresses the gap in the audit trail, giving users the ability to trace and reconcile modifications made to Intrastat reporting. The initial release includes a core set of comparison columns showing original values against modified values. The included columns are:
- Entity
- Reporting Date
- Tax Classification Code
- Intrastat Net Amount
- Invoice ID
- Invoice Date, original value

The dashboard now renders successfully for GST jurisdictions, with both chart widgets and detail grid components loading as expected and displaying the appropriate data for the selected entity and reporting period.
Corrected Sales and Purchase Amounts on the OITC Dashboard:
An issue affecting the calculation of Sales and Purchase amounts on the OIC dashboard for the UAE Jurisdiction has been resolved. The dashboard now accurately displays Input Tax, Output Tax, and Net Tax values, ensuring more reliable and consistent reporting. Known issues
No known issues are documented for this release.
