The Social Security Administration announced October 15, 2015 that there will be no cost-of-living adjustment for benefits in 2016. As determined by the Bureau of Labor Statistics, there was no increase in the CPI-W from the third quarter of 2014 to the third quarter of 2015. Therefore, under existing law, there can be no COLA in 2016. Other adjustments that would normally take effect based on changes in the national average wage index also will not take effect in January 2016. Since there is no COLA, the statute also prohibits a change in the maximum amount of earnings subject to the Social Security tax, as well as the retirement earnings test exempt amounts. These amounts will remain unchanged in 2016.
Here's a summary of all the 2016 Social Security changes.
