As a B permit holder, paying quellensteuer in Zurich, is there the possibility to overpay? Considering how this is all automated and calculated based on how much your salary comes in to be every month, I cant imagine that there's much chance of being overtaxed.
Nonetheless, is it possible to check with the tax authority to confirm that i haven't been overcharged?
Also, I have heard that beyond a specific earning threshold (CHF100K-160K, I don't know) it becomes compulsory for a B permit holder to submit a self assessment. Is this correct?
It is easy to be "overtaxed" based on the gemeinde (commune): withholding taxes do not account for the exact gemeinde they just average for the canton. So if you live in a gemeinde with low tax rate, it is more likely that your actual tax liability is lower than your withholding taxes. Another reason for this to happen is if you have some very large deductions you would be able to make on your income.
You can check with tax folks, but I doubt they will go out of their way to decide for you what is better for you to do. I'd suggest understand roughly how taxes work (in terms of income and wealth), compute approximately your taxable income and wealth and use a tax calculator to see how much you'd own - and compare that to the withholding taxes that you have paid.
If you decide to go for it - you can request your tax office until 31 March to send you the code/forms to submit your tax return.
A subsequent ordinary assessment is carried out ex officio under the following conditions:
For persons who are subject to withholding tax and are resident in the Canton of Zurich
- if a gross annual income of at least CHF 120,000 is achieved in the calendar year from gainful employment (employment relationship) (in the case of persons living in unseparated marriages, the gross income of the spouses from employment is not added together to determine the threshold value; in the case of tax liability during the year, the thresholds, the periodic gross income is converted to twelve months and the non-periodic gross wage components are included without conversion)
- if withholding tax credits are reclaimed
- if the income not subject to withholding tax (e.g. income from securities or real estate) amounts to at least CHF 3,000
- if the taxable assets (e.g. securities, real estate) of individuals amount to at least CHF 80,000 or the taxable assets of joint taxpayers amount to at least CHF 160,000
