This paper studies how much firms make unintentional mistakes in their tax filing, and to what extent this can be affected by providing information about the tax code. We utilize a novel natural field experiment design, where we candidly provide information to firms reporting their VAT within a survey. The results indicate that firms make unintentional mistakes in their tax reporting and that informing about tax rules reduces these mistakes significantly.
