Migration information

Transition to NextGen content

We've migrated the ONESOURCE Platform to the NextGen operating system and can now take advantage of new technology in the platform.
ONESOURCE is now more flexible and extendible, so our team has been redesigned the Australian ONESOURCE Corporate Tax content. This gives you streamlined data flow and other enhancements.

Benefits of NextGen content

NextGen content includes several major enhancements:
  • Greater tax sensitivity mapping
  • Automated and dynamic data flow from lead statements to supporting workpapers, tax effect accounting (TEA) workpapers, and ATO Forms
  • Streamlined workpaper management – merging and splitting of workpapers to align better with source data and lead statements
  • Enhanced workpaper analysis – additional automation and data entry options, and improved data import
  • Improved data tracing and linkage
  • New Fixed Assets module, including full fixed asset import
  • ATO Forms – cleaner workpaper style “Form” with new import functionality
  • New data reporting capability – ability to report on calculation and workpaper data

Transition process

Our Professional Services Migration Team will guide you through the process of transitioning to NextGen content. The Transition Guide outlines detailed instructions of the activities you will need to perform.

Costs and timeline

There's no additional cost to transition to NextGen content if your requirements remain within your existing agreement. Our Professional Services Migration Team will guide you through the process and outline complimentary services at your initiation meeting.
If you need extra consulting support beyond our complimentary services, or if you want to turn on paid NextGen features like APIs, we're happy to help through a separate paid engagement.
Classic content won’t support the 2025 tax year. As such, your organization will need to adopt NextGen content before using ONESOURCE Corporate Tax for your first 2025 dataset, at the latest. Our Professional Services Migration Team will assist you in working through the ideal time to transition.

Transition deadline

Classic content won’t be available for the 2025 tax year. You'll need to adopt NextGen content before using ONESOURCE Corporate Tax for your first 2025 dataset. Our Professional Services Migration Team will assist you in working through the ideal time to transition.

Revert to Classic content

You can revert to Classic content as long as Classic content supports the tax year of the calculation you are completing. However, you'll lose any work done in NextGen and will need to re-enter it if you switch back to Classic content.

Decommission of Classic content

We’ll decommission Classic content and no longer support it after the 2024 tax year. Accordingly, customers will only be able to create 2025 tax year calculations using NextGen content. However, customers will still be able to access, amend, and retrieve all historical calculations prepared using Classic content. You can electronically lodge amended returns created using Classic content through ONESOURCE e-Filing Manager.

Training and support

Our Professional Services Migration Team will host public webinars to showcase the key changes in NextGen content and to demonstrate how to use the new features. If you require additional training for your product users, we would be happy to provide you with a quote for our training services.
Once you complete your transition to NextGen content, you can raise any product-related queries through the Thomson Reuters Support Team, as is the current process. For account-related queries, contact your Client Relationship Manager.
