The present reserch project is about Taxes, that is an important topic in our society. The project has two main objectives. The most important one is to find out people's knowledge about taxes and the other part is to discover what part of our expenses are devoted to the payment of taxes.
In order to get results for these objectives, I did surveys to the population and I collected all the receipts that a random family has.
Key words: tax, tax system, expenses.
