Then, the answer is once again: sales taxes. If UBI is implemented, it should only come with a complete shift of overhead costs (government, environmental, etc) to sales tax. The standard answer of "Sales taxes are regressive!!" ignores how income taxes shift property ownership to the rich so they can be coddled and then taxed in order to 'support' the poor, who should never have given their time and property to make the rich in the first place. People make all of the major decisions at the checkouts, and they need to be informed at that point.
