SBR — Standard Business Reporting

SBR (Standard Business Reporting) is the Dutch XBRL framework that standardises all financial and fiscal declarations. Mandatory for income tax declarations since 2013, extended to VAT (BTW), KvK annual accounts and CBS reporting, it makes the Netherlands one of the most advanced countries in the world in standardised fiscal reporting via XBRL taxonomies.

History — 2007 → 2013 mandate

2004-2006 — NTP programme (Nederlands Taxonomie Project). Launched by Ministers of Finance and Justice to reduce business administrative burdens. Led by PWC + Logica + Logius.
2007 — First NT release. Nederlandse Taxonomie 1.0 (built on IFRS-NL and US-GAAP foundations), covers annual reports.
2009 — SBR Memorandum of Understanding. Signed between Belastingdienst, KvK, CBS, AFM (financial regulator) to share the taxonomy.
2013 — Income tax mandate. IB (Inkomstenbelasting) declaration via XBRL/SBR mandatory for third-party filers (accountants, tax advisors).
2014 — VAT (BTW) mandate. Omzetbelasting declaration mandatory in SBR for companies. Coexistence with ELO (Elektronisch Loket Ondernemers, legacy).
2016 — KvK annual accounts mandate. BV (LLC) mandatory, then NV (PLC) in 2017. SMEs in SBR Light since 2018.
2017-2019 — CBS and DNB extension. Economic statistics and prudential reporting.
2021 — iXBRL adopted. Inline XBRL becomes the standard for annual reports — file readable both by humans and machines.
2025 — NT2025 released. Alignment with EU ESEF (European Single Electronic Format) + ESRS extensions for CSRD sustainability reporting.

SBR Nederland governance

SBR Nederland is a consortium led by Logius, bringing together public and private stakeholders of standardised reporting:

Logius — Digipoort operator and technical architect of the framework.
Belastingdienst — tax administration (main consumer).
KvK (Kamer van Koophandel) — Chamber of Commerce, annual accounts deposit.
CBS (Centraal Bureau voor de Statistiek) — national statistics institute.
DNB (De Nederlandsche Bank) — central bank and prudential supervisor.
AFM (Autoriteit Financiële Markten) — financial markets authority.
RJ (Raad voor de Jaarverslaggeving) — Accounting Council for NT development and IFRS-NL alignment.
NBA (Koninklijke Nederlandse Beroepsorganisatie van Accountants) — Order of Accountants.

SBR + XBRL + NT architecture

SBR rests on three superposed technical pillars:

XBRL International 2.1 — the global grammar (W3C-like XBRL.org consortium). Defines instance, taxonomy, label, calculation, dimension concepts.
Nederlandse Taxonomie (NT) — the national taxonomy covering ~8 000 financial, fiscal and statistical concepts. Versioned annually (NT2024, NT2025, NT2026 planned).
SBR Standards — Dutch conventions: security profile, signature, packaging, routing via Digipoort, acknowledgment management.

Nederlandse Taxonomie (NT) — NT2025

The NT (Nederlandse Taxonomie) is the conceptual backbone of SBR. Maintained by SBR Nederland in co-leadership with the RJ (Raad voor de Jaarverslaggeving), it contains definitions of all financial and fiscal concepts used in legal declarations.

Layered architecture (entrypoints):

BD (Belastingdienst): fiscal taxonomies — income tax, corporate tax (VPB), VAT (OB), Intracom reporting (ZM).
KvK: annual accounts deposit — variants BV, NV, Stichting, Coöperatie, Fonds.
CBS: Intrastat, economic statistics, sectoral surveys.
DNB: prudential reporting for banking, insurance, pension funds.
AFM: prospectus, market supervision.
ESEF / ESRS (since NT2025): European Single Electronic Format for listed companies' annual reports + ESRS extensions for CSRD sustainability.

NT2025 (released 1 May 2025) notably adds:

ESRS-E1 (climate), E2 (pollution), E3 (water), E4 (biodiversity), E5 (circular economy) concepts
Pillar Two indicators (15% minimum tax on multinationals)
Crypto-asset concepts (MiCA TFR alignment)
IFRS S1/S2 alignment for sustainability reporting

Supported flows — Belastingdienst, KvK, CBS, DNB

iXBRL — Inline XBRL for annual report

Since 2021, the KvK annual report is filed in iXBRL (Inline XBRL) — an XHTML file containing both the human-readable layout (PDF-like) and the underlying XBRL tags. Advantages:

A single file for human reading (printable PDF) and machine consumption.
Direct alignment with EU ESEF (listed European companies).
Layout controlled by the issuer (official ESEF template).
Automated downstream validation by KvK + RJ + AFM.

Open-source iXBRL validation tools: Arelle, OpenSlate, Reporting Standard.

International fiscal XBRL comparison

Country	Fiscal XBRL mandate	Scope	NL-equivalent status
Netherlands	2013	IB, BTW, KvK, CBS, DNB	—
USA	2009 (SEC EDGAR)	10-K, 10-Q, 8-K listed companies	Advanced but listed only
UK	2011 (HMRC iXBRL)	Corporation tax + Companies House	Comparable KvK perimeter
Japan	2008 (FSA)	Listed companies + IFRS adoption	Less broad than NL
EU (ESEF)	2020 (annual reports)	Listed European companies	NL aligned via NT2025
France	2020 (DGFiP partial)	Optional fiscal balance sheet	Less developed
Germany	2013 (E-Bilanz)	Tax balance + Handelsregister	Comparable but no iXBRL
