Ms Kerswell has held the role in Northamptonshire since October 2007
The chief executive of Northamptonshire County Council, who earns £197,136, has published details of her salary online and urged others to follow suit.
Katherine Kerswell said others in her position must show they are committed to "full transparency".
Details of her salary, and expenses of £3,173 between April and November last year, are on the council's website.
Ms Kerswell is also president of the Society of Local Authority Chief Executives (Solace).
The council said the new web page is dedicated to outlining the role of its management team.
Ms Kerswell said: "It is clear that chief executive salaries continue to be an issue which generates debate.
"I believe we must act to show we are committed to full transparency on the costs of these roles and provide information to enable full understanding of the values of these roles."
