The President of the Catalan Government, Artur Mas, presented on Monday the model for Catalonia's own Treasury, which will be developed should "the political conditions" be there, he stated. "This is the most serious attempt to build our own Treasury in the last 300 years", stressed Mas. "After two years of work, we are ready" to launch and Catalans should not waste "this great opportunity", he stressed. "Without our own Treasury, there is no real self-government", the Catalan President stated. The system would include Catalonia's own Tax Agency and is inspired by the taxation authorities in countries such as Sweden, Denmark and Australia, which prioritise cooperation with taxpayers over controlling them. In these models, efforts are concentrated on severely persecuting tax evaders and underground economy, while the vast majority of tax-payers who deal correctly with their fiscal obligations receive assistance and have unlimited access to their fiscal data.
