There is no real place for this - some of the Big 4 do a little blurb on different countires, but it would not be enought to help you with this. Check out their websites just to see.
However, the best thing to do is get an advisor in each country to do a summary for you. However, note that budgets change things, and this will need to be updated regularly.
Alternatively you could get someone in Ireland to do the research for you - but it could cost you!!!
www.worldwide-tax.com is the best tax website I've found, but I would only advise people to use this a general insight to tax issues and suggest that people always appoint a specialist tax advisor.
Tax is almost always the last issue that inexperienced investors consider, but due the huge affect taxes can have by eating into your returns it should always one of the first issues to be clarified. Not only in terms of Stamp Duty, but Income Tax on your returns, Capital Gains Tax and any other local tax that may exist.
Sales agents often promote their developments as being beneficial due to being in a tax free country, leading some people to assume that because a country is tax free eg Dubai that they won't pay tax, whereas in most case you will still be liable for Irish taxes on the returns you make abroad, so speak to a professional tax advisor.
Tax is a special issue when you intend to invest into another country. I also suggest you discuss with local experts before doing anything. As Simon said, tax may change your mind because gross returns are not accurate for investors. You need to know net figures if you want to invest in.
