A review of the 2010-2018 data shows that the tax burden in Switzerland has declined during this period.

The decline is most pronounced among middle-income earners and the decline is more marked among couples with children. In addition, various changes are observed among the cantons. The income of natural persons and the profits of legal entities are not evenly distributed across the country. Some regions benefit from more advantageous resources and have therefore been able to reduce the tax rates for their taxpayers. The municipalities of the individual cantons are reclassified by the FTA according to a new indicator for the tax burden of natural persons, which adjusts the differences in resources among the municipalities.

The statistics are available here.
