Ireland has seen their Tax Freedom Day pushed back further than most countries listed, as in 2019 it took an extra 10 days for the Irish to pay off the taxman compared to the year before. Irish taxpayers had to wait until the 3 June to be free of tax. However, the Organisation for Economic Co-operation and Development (OECD) praises Ireland's tax system which it has called the second most progressive for income tax (out of 36 members), and the most progressive in the EU. The system follows the simple rule of the more you earn, the more tax you pay. So for workers on low salaries the personal tax rate is actually the second-lowest compared to the UK, the US, Germany, France, Sweden, Singapore and Switzerland, according to research by the Irish Tax Institute (ITI), but as salaries go up the scale so does the tax rate and Ireland's rankings in the International Tax Tables.
