Why make a withholding tax adjustment?

  • By being taxed at source, the cantonal tax administration applies to cross-border workers and holders of a B permit a scale that only partially takes into account the real situation of the taxpayer;
  • Apart from a few rare cases, the situation of the person who is taxed at source does not correspond to the withholding tax factors, which implies that most withholding taxpayers pay too much tax;
  • Certain expenses can also be deducted;
  • As a result, making a tax adjustment makes it possible to readjust the tax actually due and the tax paid at source;
