I live in kanton Zug and in 2020 I have been paying monthly quellensteuer.
I earn quite a regular salary, however I had 2 very nice months in the year when my monthly income was CHF 30,000 (due to stock options exercise and bonus). This caused my monthly income tax rate to increase from around 5% to 20% in these months.
Is there any practical solution to flatten out my tax rate by submitting some request to assess my income on a yearly basis? And if so, would it be beneficial at all?
Many thanks for some insight tax wizards!
