Generally when looking at the total tax burden, it’s not just income tax at play which is not so bad in Argentina (with the exception that the full rate kicks in earlier than other countries due to low thresholds and fewer deductibles) Even a 7% tax on dividends is hardly a grotesque rate of taxation and I would argue is fair given the high levels of corporate taxation on various levels and in various forms.
Where one really pays a lot of tax is on consumption of goods and services, transactions and even wealth. It’s not just IVA, it’s the 28,956 different taxes along the supply chain that are all build into the price we pay or chip away at our earnings. There was a study to show how much of the price of a bottle of Orange Juice in a supermarket here goes towards tax - answer: an obscene amount, more tax than fruit. Hence governments here are so obsessed about “consumo” and prefer to freeze prices rather than give tax breaks.
