I've been scratching my head over something and could use some insight. I'm trying to figure out how to use the Irish VAT calculator properly, but I seem to be hitting a wall. Specifically, I'm confused about which items are subject to VAT and at what rates. I've gone through the guidelines, but I'm still unsure about certain scenarios. Could someone please break it down for me in simple terms or share any tips or resources that might clarify things? Your help would be greatly appreciated!
