I'm Ann, from the team here at Shopify :)
When it comes to taxes, the rules will differ all over the world, and will definitely depend on what you're selling and where you're selling to. It's hard to say for sure if what you heard is correct or not, so your best bet will be to reach out to a local tax expert.
We do have some guides on US taxes, and Non-US taxes in our Shopify Manual that might help as well, and some basic information about taxes and Shopify here. Those guides will include all the steps on how to set up tax rules in your store. However, what rules you set up will be up to you. Talking to a local tax expert will be the best bet here, then you can make sure your store is set up correctly.
I hope this helps! If you have any more questions or concerns feel free to reach out to us on this thread :)
Have a great one,
