Will everything 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 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, you're not thinking about the register. You're thinking about where your rental data actually lives right now: the active 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 still knows how to navigate.

That one question is actually two. What is the government going to ask of you? And can you deliver that right now without setting aside a week for digging through files? The first question can't be answered definitively yet, because the proposal is still under development. The second one you can answer today, and for many teams, 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 its 2026 rental policy. The aim: to make visible which person or entity rents out which home, so tenants and municipalities know who they're dealing with. According to Volkshuisvesting Nederland, the register will list which landlords are active and which rental properties they let or intend to let. The public consultation ran from 16 April to 28 May 2026, and according to Rijksoverheid, the government wants to reach a decision on the bill before the end of this year.

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

Why waiting for the final legal text doesn't work

You could reason: it's just a proposal, the text may still change, so you'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 is always the same: first the Wet goed verhuurderschap (Good Landlordship Act), then the Wet betaalbare huur (Affordable Rent Act), and from 1 July 2026 the Wet modernisering servicekosten (Service Costs Modernisation Act), and now the rental register. Every new rule hits the same weak spot: fragmented rental data scattered across different places depending on the file.

Teams that start collecting from scratch with every legislative change pay the same price each time. If you get your data structurally in order once, you'll answer the next reporting obligation with an export instead of a project.

How to make your rental administration register ready

Register ready doesn't mean you have to submit anything right now. It means that for every rented unit, you have one place where the basic data is correct and stays up to date. Concretely:

• One source system per data point. Agree on where the single source of truth sits: 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 basic data set. Landlord, address or unit, contract type, start date, net rent and servicekosten (service costs). This set almost certainly overlaps with what a register will ask for, and it's the same set you need for the rent check and the service cost settlement.
• Digitise the scan folder selectively. Not everything needs to be searchable, but the contracts still in effect do. Start with the oldest active contracts, that's where the gaps are.
• Automate the updates, not just the storage. A clean dataset starts going stale from day one. Make sure every new tenancy and every rent adjustment lands directly in the source system, by linking your letting process to your administration instead of retyping data.

The calm between consultation and deadline

The consultation period has closed and the decision making 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 it happens", but with "our data is ready, we're just waiting on the submission format". That's the difference between a legislative change that becomes a project and one that stays an export.
