The budget for Africa's top oil producer has been held up for months as Buhari had to withdraw his original bill, which set spending at a record $30 billion, in January, due to an unrealistic oil price assumption and flaws in the draft.
Lawmakers approved an amended bill last month but said last week they would hold new talks with the government to discuss "areas of concern" after local media reported disputes over details.
"On the 2016 budget we are still talking," Udoma Udo Udoma, minister for budget and national planning told reporters. He declined further comment.
