The Withholding Tax The Swiss impose a 35% withholding tax on interest paid in Swiss francs. You can recover this money by the simple expedient of declaring the interest to the IRS. You will come out ahead doing this, because you will receive a refund, if you are in the standard 28% bracket and not subject to state or city income taxes. However, the Swiss do not issue 1099 forms, and it may be difficult to determine the appropriate exchange rate for the dollar. One way to avoid the withholding tax is to have an account denominated in a currency other than the Swiss franc. A certificate of deposit can be denominated in Swiss francs, but held outside the country. However, such accounts may be only as sound as the foreign bank into which the Swiss bank placed your money. Another, very common, way to avoid the withholding tax is to have the Swiss bank act as your money manager, in what is called a fiduciary account. All of the investments are made outside of Switzerland, in whatever you tell the bank to do -- mortgages, mutual funds, other banks. The money is merely passing through Switzerland, and is not taxed there.
