The enterprise minister said she believed the Westminster government was "inherently sympathetic" to lowering corporation tax in Northern Ireland, on 11 December 2012.
Arlene Foster was responding to a question asking if there was any update on devolving powers to reduce the tax.
She said a working group, set up to look at the matter, had completed a report which had been passed to the prime minister on 16 November.
Mrs Foster said the first and deputy ministers had also requested a meeting with David Cameron to discuss the matter.
The minister said she welcomed the Chancellor George Osborne's Autumn Statement announcement that corporation tax was to be cut to 21% from April 2014.
When asked about tourism targets, Mrs Foster said it was estimated that Northern Ireland had welcomed more than 650,000 visitors from Great Britain in the first nine months of 2012.
The minister also addressed topics such as low economic growth and spoke on the help her department was providing to contractors affected by recent redundancies in the construction sector.
Environment Minister Alex Attwood answered on topics including the Marine Bill and the councillors severance scheme.
