The survey, Aid to Recovery: The Economic Impact of IT, Software, and the Microsoft Ecosystem on the Global Economy, covers 52 countries worldwide.
IT-related activities will generate 355 million levs in taxes in 2009. Over the next four years that means more than 344 million levs in aggregate net new taxes, the survey said.
That spending growth means that employment in Bulgaria's IT industry and of IT professionals in IT-using organisations will rise by 9,000 jobs in the four years from the end of 2009 to the end of 2013, up from a 2009 base of 41,000.
That represents growth of 4.3% a year from now through 2013, while overall employment in the country of 7.7 million is expected to shrink.
Software drives activity in the services and distribution sectors, as well as in IT-using organisations, which means that while spending on packaged software will be only 13% of total IT spending in 2009, 42% of IT employment will be software-related.
The IT market will drive the creation of more than 300 new businesses in Bulgaria between now and the end of 2013. Most of these companies will be small and locally-owned organisations, IDC said.
IT spending in central and eastern Europe (CEE) will be $46 billion (31.1 billion euro) in 2009. From the end of 2008 to the end of 2013, IT spending will grow 5.8% a year across the region.
Besides Bulgaria, the other CEE countries included in the survey are Croatia, the Czech Republic, Greece, Hungary, Romania, Russia and Poland.
