Inter-Departmental Business Register
The Inter-Departmental Business Register (IDBR) is a comprehensive business register which contains information on all businesses in the UK which are VAT registered or operating a PAYE scheme. It covers most of the economy including the agriculture, production and service sectors in Northern Ireland. It does not include very small businesses which fall below the VAT and PAYE thresholds.
The IDBR is used by Government for statistical purposes. It provides a sampling frame for the vast majority of government statistical surveys to businesses. The Northern Ireland part of the register is maintained by the Economic and Labour Market Statistics Branch, Northern Ireland Statistics and Research Agency (NISRA).
