The Municipality of Budapest

Delivering and supporting the Municipality of Budapest tax administration system to date

The Local Taxes Information System (HAIR) is one of the oldest, but still efficiently functioning IT systems of the The Municipality of Budapest – Mayor’s Office. The system supports the tax-related tasks falling under the competence of local governments, including the servicing of tax returns of customers and the tax administration tasks of the Office. The proper functionality and operational security of HAIR is of utmost importance for the Office and the local government, as it has to ensure the collection of some HUF 240 billion of revenue per year, while at the same time it affects hundreds of thousands of customers, whose administrative burden has to be kept to the minimum. The system was originally developed in 1995 and implemented by Ulyssys Ltd. as a subcontractor. Due to the constant changes in tax legislation, the modernisation of available technologies and the new functional needs of the system, significant improvements are made to the system every year, and since 2010 we have been directly implementing the system as a main contractor. In recent years, these include the introduction of the electronic tax return (webHAIR), the implementation of the electronic payment facility, the renewal of the tax invoicing module (webAdó), the renewal of the control module and the development of the risk analysis module.
