Ireland's quite weird in terms of tax policy internationally. We have supposedly low rates of income tax, high sales taxes and low corporate tax. Ireland also has more deductible than I've seen in the UK. I went looking for things I could use to reduce my tax bill (there's loads in Ireland), but there appeared to be no comparable tax reliefs available for me in the UK :(.
At those rates, income tax would also be higher than in the U.S., at least for most people
In Sweden income tax can be over 60% and VAT 25%.
In some places its lower, some places higher, I presume, but I've never heard as high as 23%, I think people here wouldn't stand for that, I presume there are much better social services in Ireland, which would be the benefit of higher taxation
