This study is an attempt to analyze the insurance premium rate/load as a factor that influences the premium collection revenues for the Social Security Administration by using the Laffer curve logic and to identify the premium load that maximizes premium revenues and the improvement it would bring to the Administration. The monthly data for the period between October 2008 and December 2012 were used in the study. The results of the analysis revealed a significantly parabolic relationship between the Administration's premium revenues and insurance premium load, which is similar to the Laffer curve. The insurance premium rate that would maximize the Administration's premium revenues was found to be 39.6% and it was determined that an improvement amount of 9.4 billion TL would have been obtained for the premium revenues in 2012 if this rate had been applied.
