Launch
Pick the model from the Nudj library, set the target level, dates and participants.
Run the OECD tax administration maturity models as guided, evidence-backed self-assessments, and turn every gap into an owned improvement action.

Each model is ready to run: attributes, maturity levels and guidance are already set up, so you can start an assessment in minutes.
Assess how ready your tax administration is for joined-up, data-driven and increasingly real-time taxation, and turn the result into a roadmap.

Explore the model →The OECD models help tax administrations hold an honest conversation about where they are and where they want to be. The hard part comes after the workshop: keeping the evidence, agreeing the gaps, assigning actions and showing progress at the next assessment.
Nudj keeps all of that in one governed place. Ratings carry their reasons and evidence, assessors validate them, gaps are calculated against your own target level, and recommendations become a roadmap of owned tasks. When you run the model again, you compare the cycles and see what changed.
Pick the model from the Nudj library, set the target level, dates and participants.
Run the facilitated discussion. Each participant chooses the best-fit level for every attribute.
Record the reasons for each rating and attach supporting documents.
An assessor reviews, challenges and validates the ratings before they count.
See the result by attribute and theme, and the gap to your target level.
Turn the gaps into recommendations, a roadmap and owned tasks.
Run the model again later and compare cycles to show progress.
Seven: Digital Transformation, Analytics, Tax Compliance Burden, Enterprise Risk Management, Human Resources, Tax Debt Management, and the Tax Crime Investigation Maturity Model.
A spreadsheet records a rating. Nudj also records who rated what and why, the supporting evidence and the assessor's validation, then turns the gaps into recommendations, a roadmap and owned tasks, and compares each cycle with the last.
Yes. Each model is a separate assessment with its own participants, target and results, all in one place.
No. The models are published by the OECD. Nudj is an independent platform for running assessments based on them.
Nudj's interface works in English and Arabic, including right-to-left layout. The OECD model content is in English.
