An alias was made a bank deposit deadline. The gross rate was 1.9% (around 137E). The contract but there was a tax deposits 70E 7E + VAT (77E to taxes). The actual rate he was about 63E, just 0.95% net. Thus, the tax savings was about 50% and not 10%. If the tax was 10% real interest rate should be 1.71%. Question: Does the amount varies from bank to bank? If so is there a website that concentrated taxes deposits of banks? If not how is the tax instead of 10% is over 50%?
