NoordelijkBelastingkantoor

What NoordelijkBelastingkantoor does

Noordelijk Belastingkantoor is a Dutch public-sector tax collection agency operating as a gemeenschappelijke regeling (joint administrative arrangement) under Dutch public law, headquartered in Haren, Groningen. The organization levies and collects municipal taxes (including OZB, waste collection fees, sewerage charges, tourist tax, parking fees, and reclamebelasting) and water board taxes (water system levies, purification charges, and pollution levies) on behalf of six municipalities — Groningen, Eemsdelta, Noordenveld, Oldambt, Pekela, and (effective 19 May 2026) Achtkarselen — and three water boards: Waterschap Hunze en Aa's, Waterschap Noorderzijlvest, and Wetterskip Fryslân. It also determines WOZ (Wet Waardering Onroerende Zaken) property valuations for the municipalities in its service area and issues approximately one million tax assessments per year to citizens and businesses.

The organization's product surface centers on the MijnNoordelijkBelastingkantoor online portal, where individual citizens authenticate via DigiD and businesses via eHerkenning (EH3) to view assessments, submit objections, request installment plans, and apply for exoneration. Supporting modules include a WOZ calculator, MijnOverheid Berichtenbox integration for official digital delivery, an e-Notaris portal exposing tax and WOZ data to notaries during property transactions, and a physical counter at Raadhuisplein 10 in Haren. The underlying technology stack is predominantly off-the-shelf government infrastructure: a WordPress-based public website (technically realized by Convident), ZIVVER for secure communications, Google Analytics with IP anonymization, and authenticated integrations with national base registries including BRP, BRK, BAG, WOZ LV, RDW, KvK, and the Inlichtingenbureau.

Noordelijk Belastingkantoor is not a commercial enterprise and does not charge citizens directly. Its operating budget is funded by participating municipalities and water boards, and tax rates and tariffs are set annually by the respective municipal councils and water boards. There are no funding rounds, investors, or parent-company relationships; the entity is governed by a four-member board and is publicly accountable to its participating authorities rather than to private shareholders.
