About 430 Queensland government IT jobs could go next financial year and the minister won't guarantee work will stay onshore.

The state government is divesting its technology services provider, Centre for Information Technology and Communications (CITEC), within two years as part of a cost cutting drive foreshadowed in June. In total some 1700 IT jobs are under likely to go.

The government's information communications technology deputy director-general, Andrew Spina, told a budget estimates hearing on Tuesday job losses were expected to be finalised after a review was handed down in two months time.

"If you look at the service delivery statement, we've identified a reduction of staff for next financial year, which represents a movement of corporate resources and a movement of resources from the chief technology office to a number of 430," he said.

"Depending on what the outcomes of that review are, we would obviously be considering what other options there would be and what would need to occur with staff overall."
