OECD Tax Administration Maturity Model Series2022 model
OECD Digital Transformation Maturity Model: self-assessment tool
Assess how ready your tax administration is for joined-up, data-driven and increasingly real-time taxation, and turn the result into a roadmap.
About the model
What the Digital Transformation model measures
The Digital Transformation Maturity Model describes how a tax administration moves from digitising individual functions and offering e-services towards joined-up processes that are built into the systems taxpayers already use.
It covers digital identity, how taxpayers reach the administration, the data behind it, how tax rules are written and applied, the skills digital work needs, and the governance that holds it together.

What is assessed
The 13 attributes, by theme
Each attribute is rated at the level that best describes the administration today. Not every statement under a level has to be met; the aim is the best overall fit, backed by evidence.

Maturity levels
5 levels, from Emerging to Aspirational
The model describes a direction of travel, not a pass mark. There is no single right level for every administration: you choose the target that fits your context, and Nudj measures the gap to it.
Emerging
Capabilities exist in pockets and depend on individuals; practice is ad hoc and often reactive.
Progressing
Some processes are in place and understood, but they are applied unevenly across the administration.
Established
Processes are standard, coordinated and part of how the administration routinely works.
Leading
Practice is integrated with strategy and performance management and continuously improved.
Aspirational
A forward-looking position few administrations reach yet, often using advanced data and technology.
How it works in Nudj
From self-assessment to an improvement plan.
Discuss
Run the facilitated discussion. Each participant chooses the best-fit level for every attribute.
Evidence
Record the reasons for each rating and attach supporting documents.
Validate
An assessor reviews, challenges and validates the ratings before they count.
Analyse
See the result by attribute and theme, and the gap to your target level.
Act
Turn the gaps into recommendations, a roadmap and owned tasks.
Re-assess
Run the model again later and compare cycles to show progress.
Running the session
Who should take part
ParticipantsBusiness, technology, data, tax policy and operations, taxpayer service, security, HR and governance leads, so that every theme is discussed by the people who own it.

FAQ
Questions about the Digital Transformation model in Nudj
Is this the official OECD Digital Transformation Maturity Model?
Nudj's assessment follows the structure of the OECD Digital Transformation Maturity Model as published by the OECD: the same attributes and the same 5 maturity levels. Nudj is not affiliated with the OECD; we recommend that participants also have the OECD publication to hand.
Can we run the Digital Transformation model as a self-assessment?
Yes. The model is designed as a facilitated self-assessment. Nudj supports a single facilitated session or several respondents rating separately, with an assessor validating the results.
How long does the assessment take?
Typically one to two facilitated workshops, depending on preparation.
Can we compare results over time?
Yes. Each run is a separate assessment event, and Nudj compares cycles side by side so you can show progress against your target.
Is Nudj available in Arabic?
Nudj's interface works in English and Arabic, including right-to-left layout. The OECD model content itself is in English.
Can we add our own questions or use other frameworks?
Yes. You can extend a built-in model with your own questions, and use Nudj's framework builder for your organisation's own models alongside the OECD ones.
Which parts of the administration does the digital transformation model cover?
All of them. It looks at digital identity, taxpayer touchpoints, data, tax rules, skills and governance, so it works best as a cross-functional exercise rather than an IT-only review.
