FiNK – Fiscal Estates in NRW
With FiNK, NRW is digitizing the specialist procedure for fiscal estates – on reusable low-code building blocks, so that other federal states can reuse it instead of developing from scratch.

The project
When someone in NRW dies and nobody accepts the inheritance, the state inherits. And everything with it: bank account, rented apartment, phone contract, subscriptions and sometimes debts too.
That is what FiNK is for – introduced together with the Ministry of Finance of the State of North Rhine-Westphalia and IT.NRW:
30years
Heirs can come forward up to 30 years later, so every euro must still be accountable after three decades.
We built reusable components and developed them step by step with the department and its users.
Other federal states can adopt FiNK instead of reinventing the wheel.
The digital register of estates is accessible to the administration and to citizens, legally sound and GDPR-compliant.
Thank you to the Ministry of Finance of the State of North Rhine-Westphalia, IT.NRW and T-Systems for the collaboration and trust. And to our team, who dived into estate procedures and limitation periods with enthusiasm.
Reuse
FiNK, proven in NRW, becomes a framework every state can build on.
This framework serves as the basis for other federal states.
Each state adapts only what is different for it.
A shared base carries the business logic; layers for individual tenants, regions, or regulatory variants sit on top of it. If something fundamental changes, it's adjusted once at the base and takes effect everywhere – if something local changes, it stays confined to its own layer.
Inheritance instead of copying – the Situational Layer Cake
This work is carried out by Greenfield AG in close partnership with the Low-Code Competence Center.
Situational Layer Cake
Production line
That is why, together with IT.NRW, we are building a production line for low-code applications, so that the next specialist procedures are created faster and with consistent quality.

One platform for all specialist procedures.
Consistent NRW design and single sign-on integration.
Reusable components, e.g. the e-file interface and basic data for natural persons.
Infrastructure integration, Pega upgrades, assessment of implementation requests, support with deployments, management and updating of components.
The Low Code Public Toolkit helps public authorities that want to digitize and automate their administrative work end to end – with a significant reduction in implementation time and a real increase in their digital sovereignty.
