What GBLT does
GBLT is a Dutch public-sector shared service organization (samenwerkingsverband) that levies and collects municipal and water board taxes on behalf of 10 member municipalities and 5 water boards across the Netherlands. Established in 2011 and headquartered in Zwolle, it handles the full lifecycle of local tax administration — property valuation (WOZ), assessment issuance, payment processing, objection handling, remission determination, and enforcement — for residents, businesses, and property owners in its catchment area. The organization is governed by aldermen from member municipalities and representatives from member water boards, with funding derived from member dues rather than direct charges to taxpayers.
The core digital product is MijnGBLT (mijnloket.gblt.nl), a secure 24/7 self-service portal accessible via DigiD for individuals and eHerkenning (EH2+) for businesses, also supporting eIDAS for EU cross-border authentication. Supporting products include a separate digital water board tax return portal for businesses, and the Webis Onvermogenportaal for administrators and debt counselors. Tax assessment delivery occurs through the national MijnOverheid Berichtenbox digital mailbox as the preferred channel, alongside physical mail. Customer service is delivered via phone (up to 5,000 calls/day at 95% answer rate), in-person appointments at the Zwolle office, and digital channels. Notable features include automated remission eligibility determination shown directly on tax assessments, a Diftar differentiated waste-tariff system in select municipalities, free WOZ objection processing, and proactive payment reminders before final notices.
GBLT's revenue model is fundamentally different from a commercial enterprise: it is funded by service-level dues from its 15 commissioning public-sector members rather than transactional fees from end users. It collects a wide range of municipal taxes (OZB/property tax, afvalstoffenheffing/waste, rioolheffing/sewerage, dog tax, tourist tax, advertising tax, BIZ contributions, etc.) and water board taxes (zuiveringsheffing, verontreinigingsheffing, watersysteemheffing), which are passed through to the respective member organizations. With 101-250 employees, GBLT represents a consolidated back-office function for small-to-mid-sized Dutch municipalities that would otherwise lack the scale to operate equivalent tax administration independently.

GBLT competitors and assessment
Company assessmentBroad incumbents
- ADP: Large-scale payroll, tax filing and government-levy services provider. Comparable in operating-model terms — recurring fee-based tax and statutory payment processing — providing a benchmark for high-volume, compliance-driven back-office services similar to GBLT's collection function.
- Capita: UK outsourcing and government services group with revenues-and-benefits, council tax, and digital local-government capabilities. Comparable to GBLT in scale and breadth of public-sector back-office services, though operating through a private commercial model rather than a member-funded scheme.
- Belastingdienst (Dutch Tax and Customs Administration): The national Dutch tax authority. While it operates at a different (national) layer and not as a shared service, it sets the legal and procedural baseline within which GBLT must operate and represents the broader incumbent benchmark for tax-administration digital services in the Netherlands.
- Civica: Large UK-headquartered supplier of software and outsourced services to local government, including revenues & benefits platforms. Comparable as a technology-and-services incumbent delivering back-office tax and benefits administration at scale, providing a useful international peer for shared-service operating models.
- Wolters Kluwer: Global provider of tax compliance, regulatory and administrative software widely used by tax authorities and corporations. Comparable as an enabling technology provider adjacent to GBLT's tax-assessment workflow (rate lookup, valuation references, compliance rules).
Direct peers
- Gemeentebelastingen Amsterdam: Municipal tax authority for the City of Amsterdam, performing OZB, waste and water-board tax collection for one very large principal. Useful peer for assessing scale economics and digital service models in metropolitan contexts parallel to GBLT's multi-municipality approach.
- BsGW (Belastingsamenwerking Gemeenten en Waterschappen): Dutch joint arrangement that, like GBLT, levies and collects municipal and water board taxes on behalf of multiple municipalities and waterschappen in Limburg. Operates with the same statutory logic, similar customer base of principals, and an overlapping digital portal model — making it the closest functional comparator to GBLT.
- SVHW (Samenwerkingsverband Hoeksche Waard): Dutch joint arrangement for tax and social services serving a smaller cluster of municipalities. Comparable to GBLT as a regional shared-service entity performing tax collection (OZB, waste, water board) on behalf of member governments.
- BghU (Belastingsamenwerking Gemeenten en Hoogheemraadschap Utrecht): Joint tax collection scheme for municipalities and the Hoogheemraadschap in the Utrecht region, with a near-identical service portfolio (OZB, waste, sewerage, water board taxes, WOZ). Geographic complement to GBLT and the canonical example of a competing Dutch shared tax service.
- Gemeentebelastingen Rotterdam: Municipal tax collection function within the City of Rotterdam. Comparable to GBLT as a Dutch local-government tax administrator with digital assessment, payment, and objection services for residents and businesses.
