Does Apple recover tax paid to government on sales on apps? I signed up to sell my apps on the Apple app stores, and the agreement says:


  Apple shall collect and remit to the competent tax authorities the
  taxes described in Section 3.2 of this Schedule 2 for sales of the
  Licensed Applications to End-Users located in the following countries,
  as updated from time to time via the iTunes Connect site:
  
  Albania Australia Austria Belgium Bulgaria Canada China* Croatia
  Cyprus Czech Republic Denmark Estonia Finland France Germany Greece
  Hungary Iceland Ireland Italy Latvia Lithuania Luxembourg Malta,
  Republic of Netherlands New Zealand++ Norway Poland Portugal Romania
  Slovakia South Africa Slovenia Spain Sweden Switzerland United Kingdom
  United States


Does Apple recover this tax from me? In other words, will I end up paying more than 30% to Apple when a user from one of these countries buys my app?
Apple handles the sales of your app. Technically Apple is the seller, so they collect the taxes. That is why Apple gets 30% of every sold app. 

The 70% you get from an app sale are royalties. You only need to add it to your Income Tax.
