On the subscription page it states:
Total is VAT/GST inclusive where applicable
Below all the subscription choices. Then before you even complete your order if you read the fine print below it says:
By making your subscription purchase today, you authorize EA to automatically charge the then-current renewal subscription fee (plus applicable taxes or inclusive of applicable taxes based on billing address) to your credit or debit card or other available payment method on each renewal date without any additional action by you.
Then at the very bottom of the page it states:
Sales tax may apply for your region. Click here for details.
The link it goes it states:
You will see a charge on your credit card the day after placing your purchase. It will appear as Electronic Arts - Origin on your statement.
You may see a small transaction appear on your account's online statement within a day or two of any pre-order purchase or update to your stored payment method. These are temporary transactions we use to verify the payment information. The transactions automatically reverse within seven business days.
Applicable sales taxes will be added to the price you see when placing your order.
As @Dassvidanja stated above, this is a tax charged and collected based on local government rules for sales tax. This money does not go to Bioware or EA but your local government.
