ATC | Orbitax Enablement Services
Helping tax teams implement, adopt, file and independently operate Orbitax solutions with real ownership over the platform.
Supported on the Orbitax platform
Netherlands-based finance and tax technology consultancy, more than 20 years
Software functionality, connected to day-to-day tax compliance execution
ATC is a Netherlands-based Finance & Tax Technology consultancy focused on tax compliance, tax reporting, implementation support and reporting automation for more than 20 years. During those years we have been supporting multinationals as with tax technology journey. As an Orbitax enablement partner, ATC helps clients move from software implementation to practical day-to-day use.
ATC supports multinational tax teams with the practical implementation
We support clients with structured implementation, data loading, process setup, user training, filing readiness and first filing support. Our approach is deliberately focused on operational adoption: the solution should not only be implemented, but also used effectively for real filing cycles. Clients should gain the ownership, confidence and practical knowledge to operate Orbitax themselves, complete filings through the platform and continuously improve how they use the solution in-house.
One partner, three ways ATC helps
ATC acts as a hands-on implementation and enablement partner for Orbitax clients. Rather than positioning ATC as a traditional tax consultancy firm, the emphasis is on helping clients operationalize the software in a pragmatic and controlled way.
With ATC as a partner, the client team learns how Orbitax works in practice. We guide users through the setup, data model, workflow, review steps and filing outputs, so they can make informed decisions, complete filings with the solution, manage changes and gradually take full ownership of the platform.

GMT Enablement approach,
from initial setup to filing execution
The GMT Enablement is a structured implementation approach for clients implementing Orbitax Global Minimum Tax. It focuses on moving the client from initial setup to usable outputs, filing readiness, practical filing execution, optimal platform use and handover
Potential scopes
GMT process walkthrough and project setup
Entity and optional transaction data setup
Safe Harbor input support
GloBE income and covered taxes data support
Additional information and elections support from a process perspective
Country calculator and output review support
GIR and reporting readiness support
Final user training and handover
The GMT Enablement gives clients a structured route from implementation to filing execution and operating model, with a strong emphasis on practical use, knowledge transfer and future self-sufficiency.
CbCR Accelerator, a practical kickstart
The CbCR Accelerator is intended as a practical kickstart for a faster Orbitax GMT setup. Instead of starting from a blank environment, ATC uses existing data sources as CbCR XML files or 1120 tax return output to build an initial structure in Orbitax. This provides a strong starting point for the GMT process, after which the setup can be enriched with additional entity, tax, Safe Harbor and GloBE information where needed to move towards GMT compliance.
Potential scopes
01
Project kick-off and assessment of available source data, including CbCR output, CbCR XML files or 1120 tax return output
02
Mapping of existing data into an initial Orbitax GMT structure
03
Creation of a first-pass entity, jurisdiction and data framework for GMT reporting
04
Identification of missing information required to complete the GMT compliance process
05
Enrichment with additional GMT inputs, including Safe Harbor, GloBE income, covered taxes and elections where relevant
06
Review of data quality, completeness and consistency before running GMT calculations and outputs
07
Support with Orbitax workflow, data review and practical use of the generated GMT setup
08
Preparation of usable initial GMT outputs as a basis for further review, validation and compliance completion
09
Knowledge transfer so the client understands how existing data has been converted into the Orbitax GMT structure
10
Final user training and handover for further in-house completion of the GMT compliance process
Filing readiness and filing support
This service line is relevant for clients that already have Orbitax implemented, but need practical support to get ready for their first filing, complete a specific filing cycle or improve how they use the platform in practice. The focus is on turning the implemented solution into a working filing process, including output review, dry runs, submission support where applicable and follow-up after filing.
Filing readiness review
Review of required outputs from a process perspective
Dry run of filing steps
First filing assistance
Submission support where ATC has the relevant filing role and mandate
Follow-up on submission status where applicable
Built around client ownership
Hands-on and practical
ATC focuses on making the software usable in the client's day-to-day compliance process.
Compliance and reporting focus
The positioning is aligned with tax compliance, financial reporting and reporting automation, not tax advisory.
Technology-focused but process-aware
ATC combines system implementation support with understanding of the underlying reporting process and regulations.
Flexible alternative
Clients can choose from modular service menu items rather than a heavy full-scope consulting model.
Knowledge transfer
The aim is to help clients take ownership of Orbitax, understand how the tool works and avoid unnecessary long term dependency on external support.
In-house ownership
ATC’s enablement model is built around making the client autonomous: able to run the platform, manage the process and understand the logic behind the outputs internally.
