The question: I am a maternal assistant and with the introduction of the levy at source on January 1, 2020, I wonder. For example, will my employers have access to my tax situation?
Service-public's response: The tax rate that is transmitted by the tax administration to Cesu or Pajemploi does not reveal any specific information about your situation or the overall level of your income. In fact, the same rate can correspond to very different situations.
Furthermore, you are the one who chooses the rate transmitted: personalized rate, neutral rate...
At the time of filing, your employer is only informed of the amount of net salary deducted from the tax amount.
FYI
If you have any questions about how to apply the withholding tax, the Cesu and Pajemploi will make the website available to you monprelevementalasource.urssaf.fr to accompany you.
