Homework for Grown-Ups Making Sense of Foreign Filings?

Hi everyone,I was helping a Class 2 student with a project about "Global Neighbors" today, and it actually reminded me that I promised to look up some tax info for my cousin who’s setting up a shop in Kyiv!To stay professional and high-quality in my advice, I need to find the latest updates on entrepreneur VAT calculation Ukraine.I want to make sure I’m giving him established facts so his new business venture gets off to a smooth start. Does anyone here have a reliable spreadsheet template or a calculator they use for these specific regional filings?Thanks in advance.
