Social security base is getting higher and higher wages do not rise

Whether the social security contribution base goes up or not when wages go up is dependent on when your wages are adjusted. If the wage adjustment takes effect exactly the same time as the social security contribution base adjustment, then both will rise accordingly. However, if wages rise at the end of the year, the social security contribution base will generally change only in July of the following year.
