Hi, everybody!

Could you, please, tell me something about taxes in Aargau?
How much will a B holder's permit bonus, representing 34.000 CHF, be taxed, if payed all in one month?

Would taxes be lower if the bonus were split into 3-4 parts along several months?

Thanks for answering.
Regards.

Taxation at source is based on overall yearly income regardless of the payment form and a bonus is likely to push you over into a higher tax bracket which applies to your whole compensation.

I trust your skills to find the threads where links to online tax calculators are given.
