Will all this soon have to go into the national rental register? Here's how to get your rental data in order now

The question arrives via Teams, with a link to a news article. "Will we soon have to put all our rental contracts into a national register?" Your colleague means it as a quick aside. But as you read the message, it's not the register you're thinking about. You're thinking about where your rental data actually lives right now: the current contracts in your management system, the rent breakdown in a separate spreadsheet, and the oldest files as scans in a folder that only your most experienced colleague can still navigate.

That one question is really two. What will the government ask of you? And can you deliver that right now without setting aside a week for searching? The first question can't yet be answered definitively, because the proposal is still being developed. The second one you can answer today, and for many organisations that answer is more uncomfortable than the register itself.

What the national rental register will record

The government announced the rental register in December 2025 as part of the 2026 rental policy. The aim: to make visible which person or organisation lets which property, so that tenants and municipalities know who they're dealing with. According to Volkshuisvesting Nederland, the register will list which landlords are active and which properties they let or intend to let. The internet consultation ran from 16 April to 28 May 2026, and according to Rijksoverheid, the government wants to decide on the bill before the end of this year.

The scope is substantial. Around 40% of homes in the Netherlands are rental properties, so almost every property manager, housing corporation (woningcorporatie) and private landlord will be affected. How the submission will work technically is still open. But you can already guess what data it will require: who's letting, which address, and very likely characteristics of the tenancy that municipalities need for oversight.

Why waiting for the final legal text doesn't work

You could reason: it's a proposal, the text may still change, so we'll look at it next year. That's true for the legal details. It isn't true for your data. The pattern of recent years has been the same every time: first the Wet goed verhuurderschap (Good Rental Practices Act), then the Affordable Rent Act (Wet betaalbare huur), then the Service Charge Modernisation Act (Wet modernisering servicekosten) on 1 July 2026, and now the rental register. Every new rule hits the same weak spot: fragmented rental data stored in a different place for every file.

Organisations that start collecting data from scratch with every new law pay the same price every time. Once you've put your data in structural order, you can answer the next submission requirement with an export instead of a project.

How to make your rental administration register ready

Register ready doesn't mean you need to submit anything now. It means that for every let unit, you have a single place where the core data is correct and stays up to date. In practice:

• One source system per data point. Agree on where the single source of truth lives: contract data in your management system, not in a parallel spreadsheet. Every duplicate you clean up today is a discrepancy you won't have to chase down later.
• Complete the core data set. Landlord, address or unit, contract type, start date, base rent and servicekosten (service charges). This set almost certainly overlaps with what a register will ask for, and it's the same set you need for the rent price check and the service charge settlement.
• Digitise the scans folder in a targeted way. Not everything needs to be searchable, but the contracts that are still running do. Start with the oldest active contracts, that's where the gaps are.
• Automate the updates, not just the storage. A clean dataset starts ageing from day one. Make sure every new tenancy and every rent adjustment lands directly in the source system, by connecting your letting process to your administration instead of retyping data between them.

The calm between consultation and deadline

The consultation period has closed and the decision making process is underway. That gives you a rare quiet moment: you know something is coming, but the deadline hasn't been set yet. Use that space. Then you won't answer your colleague's question with "we'll figure that out when the time comes", but with "our data is ready, we're just waiting for the submission format". That's the difference between a change in the law that becomes a project and one that stays an export.
