Basically, it is very expensive! You are not liable for customs tax but are liable for excise AND Vat. Excise is huge. For example, on sparkling wine (which was the subject of my research) it is currently €546.01 per 100 litres. This changes every year. So for 60 litres (80 bottles) that worked out at €327.61 and then they charge 21% Vat on the ENTIRE amount.
Here is a useful link to a revenue leaflet that I finally located after much fannying about; http://www.revenue.ie/index.htm?/leaflets/pn1882.htm
Useful contact emails also; [email protected] and [email protected]
Found them very prompt and clear in their responses. Even if I didn't like the information
Hope this is helpful
