Thomson Reuters' content team constantly monitors changes in ONESOURCE Indirect Tax Legislation, ensuring our content supports the latest requirements from the covered jurisdictions.
Germany ESL
– the encoding of exportable csv output files used for filing has been updated to match the tax administration requirements.France VAT return:
the return has been updated to include new section with boxes related to Increase in excise. The new boxes are MA, M1, M4, M7, MB, M2, M5, M8, MC, M3, M6, M9.Slovakia VAT:
the return has been updated to conform with a new VAT return form starting from the July 2025 tax period. The updated form, titled DPHv25, incorporates significant changes, particularly in the way businesses must report import VAT under the reverse charge mechanism. This will include new boxes and remapping of existing tax codes to support the new reporting requirements.New fields for import VAT reporting include Output VAT Boxes 11c to 12e and Input VAT Boxes 23a to 23c.
Additionally there are sub fields added to existing box numbers with numbering ‘a’ and ‘b’ to provide more granularity in reporting transactions using reduced rates.
VAT returns/listings
Australia:
the formulas have been updated in the Return Summary sheets to ensure the transfer of deferred GST in box 20 is not duplicated and is performed only in the group return if there is a group structure. Previously the transfer happened both in the child return and on group level causing discrepancies. Belgium:
Updated formula for "Adjustment to exclude VAT for credit notes reverse charge as per Belgian Tax Authorities (points 230/231)" in boxes 61/62 in A2 sheet to be visible in case if the value appears.Czechia Control statement:
resolved an issue causing duplicate line entries in section B.2 of the CZ VAT Control Statement when a single InvoiceID is recorded with multiple tax codes. Hungary DSPL listing:
new logic has been implemented to ensure VAT amounts are correctly aggregated in a scenario where the same Invoice Number is used on multiple line items. Previously OIC displayed separate lines per tax rate in DSPL, which is against legal requirements – only one line per the same document number is allowed.Management information consolidation issue
- A fix has been introduced for an issue related to the B5 Annual Management information sheet. This will ensure “VAT due repayable” and “VAT due repayable before adjustments” are being consolidated correctly in both periodic and annual returns (B and B1 in Management Information sheet). This change applies to Austria and Germany templates.Netherlands:
a warning has been added to alert users to mismatches between return values in box 3b of the VAT return (this box includes all intracommunity supplies) and aggregated amounts in the ESL listings sheet. The error can be disregarded before filing if the differences are immaterial.New Zealand:
the pdf form has been updated to reflect the layout of the latest version including the section with refunds.Tax codes
Austria
– new tax codes have been added to allow reporting on Reverse Charge services from non-established suppliers with more granularity and differentiate between EU and non -EU suppliers to match the tax code descriptions to the ones used in other jurisdiction.- Reverse charge services - Services purchased by a non-EU supplier - AP_NONEUSUPSRV
- Reverse charge services - Services purchased by an EU-supplier - AP_EUSUPSRV
France
- a new tax code has been created to automat reporting of transactions related to Consumption of Oil products (AR_CONOIL) in box F4.Slovakia

Increased visibility of ‘Return Status’ through expansion of ‘ONESOURCE Events’:
ONESOURCE Events is an enhancement to the automation capabilities supported through the Compliance APIs. This tool allows customers to implement efficient processes which are driven by activities or updates within the Compliance application, meaning the next step in the compliance operations can be immediately performed either automatically or the relevant team member notified that the system is ready for them to commence the next task. Using ONESOURCE Events, customers can ensure they are promptly notified in case of any changes in the system, whether it’s to configuration, user access, data integrity, or any other action/task that can be performed within the system that the team would like to monitor. With this release, for customers who have implemented ONESOURCE Events, users can leverage this functionality to automatically be notified when there is a change in the ‘Return Status’. For any further queries and information about ONESOURCE Events, please contact the ONESOURCE Indirect Compliance support/account management team.
Imports
Advanced Import - Ensuring Accurate Uploads:
An improvement has been made to the advanced import process for the AUGAT and AUGST template families. Previously, selecting a template family during import would trigger uploads for all returns with matching reporting dates for the imported entities, regardless of the template family used to create them.With the new update, selecting either the AUGAT or AUGST template family during the advanced import process will now exclusively initiate uploads for returns created using the selected template family. This enhancement ensures accurate uploads, eliminating false uploads and providing users with a clearer and more efficient experience.
Data mapping preview format fix
: Display format of reporting dates values seen during the data mapping preview screen when importing data from XSLX files during advanced import have been corrected.Resolution of Inconsistent Transaction Deferral during Bulk Operation:
A recently identified issue caused some transactions to not be deferred during bulk operations when the application's time zone was set to the UK and filtering by invoice date was applied. This was due to an incorrect filter definition that resulted in an inaccurate count of processed transactions. This has now been resolved with an update that ensures the correct filter is applied, ensuring all selected transactions are accurately deferred to the intended reporting date.Other updates
Enhancements to Returns screen:
The Returns screen has been enhanced to enable users to effectively filter through return data, improving usability and data access.- The screen previously labeledAll Returnshas been renamed toReturns up to 2 years.
- TheReturns up to 2 yearsscreen will automatically display datasets created within a two-year date range, calculated from the current date to two years prior, based on the dataset creation date.
- The screen previously labeled 'All Returns with Count' has been renamed to 'Returns by Date'.
- When selectingReturns by Date, users will have access to a date picker, allowing them to specify a custom date range for displaying datasets based on their creation date that can go beyond 2 years as well.
- The default date range for the date picker is set to one year. Users can extend this range up to a maximum of two years between the "from" and "to" dates, providing flexibility in data selection.
- Error messages will guide users in selecting valid date ranges using the date picker.

If the updated label names, 'Returns up to 2 years' and 'Returns by Date' are not visible, clear your browser's cache, local storage, and session storage, then log back in to see the changes.
New standard report for transaction details along with warnings:
This release we have added a new standard report titled 'Transaction details - transactional information with warnings'. This report provides users with detailed insights into transactional data, including any warnings for a selected entity within a time-period. This will enable users to get a view of all plausible warnings in one go alongside the imported transactions. It aims to enhance data management & reviewing by offering comprehensive and actionable information.
note
This report will be functional from the API in the upcoming release.
Enhancement of API processing:
Internal API infrastructure within OIC has been enhanced to support processing and downloading of reports using API which enables users to work with huge volumes of data as well without any errors.Support for Zipping Exported Files for Slovenia VAT Ledgers
: To meet the requirements of Slovenia tax authorities, the exported Slovenia VAT Ledgers data will now be automatically zipped, eliminating the need for users to manually zip the files each month for submission.Enhancements to SAF_T Business Validation Messages:
SAF_T business validation messages have been enhanced to provide more user-friendly and clear messages. These improvements fall into two categories:Simplified the message content

New alert message during AU Bulk E-Filing process:
The bulk e-filing processs has been enhanced to now display an alert message on the ‘Returns screen’ altering the user when data upload to workbook is still in progress.
