The 'Tax rates' feature allows you to create multiple tax rates that you can apply to anything that is sold with Jomres (booking prices, subscription prices, extras, etc).
This feature was designed to help property owners from different countries to easily adapt Jomres to their country tax legislation. Different countries have different VAT, some have tourist taxes, some have different VAT for services (like bookings) and different VAT for products (extras like 'breakfast').
Don`t worry now about associating taxes to different products (booking prices, extras, etc). This will be done from the frontend when setting up your property. For now, we will concentrate to define all possible taxes for the country in which you offer accommodation.
