You are going to have to go in and manually add the sales tax per country into the system for both in-person and online. Unlike other some other features, the sales tax will not sync over from your Square Dashboard to your Square Online Dashboard. I hope that helps! Please let me know if you have any other questions.
To set up taxes for Square Online:
1. Open the Square Online Overview page.
2. Select Shared Settings > Sales Taxes.
To setup taxes for Point of Sale:
1. Visit Account & Settings in your online Square Dashboard > Business information > Sales tax.
2. Click Create tax.
3. Enter the tax name, rate, and locations where the tax applies.

Note: You can choose to Add Tax to Item Price, which adds the tax as a separate line item to the price or Include tax in item price, which shows one amount – the combined sales tax and item price.
5. Click Save.
