Frontier Research's Thilina Panduwawala highlighted that average monthly revenue has been above Rs. 300 billion, with quarterly income tax payments contributing to the May peak.

Meanwhile, total expenditure and net lending decreased to Rs. 1,986.0 billion from January to May 2024, down from Rs. 2,137.1 billion in 2023, leading to a primary surplus of Rs. 550 billion, surpassing the IMF's expectation of Rs. 323 billion for the year. The overall budget deficit reduced to Rs. 366.8 billion, compared to Rs. 1,014.7 billion in the previous year, marking a significant improvement in fiscal stability.
