Yo everybody! I filed my 2020 tax declaration, received (without surprises) the final federal, cantonal, city tax bills and paid in full what was due. All set! Now I've just found out in ICTax that the income generated by an ETF I owned on Dec 31, 2020 was slightly adjusted upwards; should I expect a "post-final" tax bill? Or are final tax bills really final? Ciao! Giorgio
N.B. the correction on ICTax took place after I settled my final tax bills.
