You are directly contradicting what the parent is commenting on. I honestly can’t tell if your current comment is trying to be sarcastic, but you are clearly not putting forth consistent arguments. I personally sincerely doubt EU vat is straightforward. Accounting itself is not straight forward and you can’t do any taxes without accounting. I’m a big fan of corporations paying for failure in compliance, but your tone could be slightly more generous. 25 years could be a big deal if one country requires fifo cost accounting and another requires lifo cost accounting. Do you comply with the one that puts you in jail? do you keep 2 books? do you keep seperate books for each country? Then, which do you actually use to make business decisions? These are kind of hard questions to answer, and can require considerable resources.
