Lots of comments on here from people who don't understand how EU VAT works.
Firstly, while there are general rules for where VAT should be charged on goods and services there are various exceptions for certain goods and services and also some differences for certain services based on where they are used and enjoyed.
For those saying this isn't compliant with EU law: you're wrong. The whole point of this UK law change is to make UK VAT law compliant with EU wide changes to how VAT is charged on certain services, notably electronic services like downloads, from Jan 2015.
Don't think this will just affect the UK, it will affect other EU countries too.
As has been mentioned the motivation for this change is to stop large companies gaining a competitive advantage over local businesses by setting up shop where VAT rates are lower (Luxembourg mainly). This is particularly notable for ebooks as the rate is only 3% vs 20% in the UK. So expect the biggest price increases to be on ebooks.
The biggest problem is the impact this will have on smaller businesses, ironically, as it will mean any VAT registered UK company selling downloads will have to charge and account for VAT in the buyers country.
To keep things simple the UK government will be introducing the Mini One Stop Shop (MOSS) which will allow sellers to register for VAT in just one country (the UK) and the UK (HMRC) will remit the VAT to other countries for you.
Either way it still sounds like a burden to me.
IMO it would have been far simpler to harmonise rates on electronically supplied services across the EU given their intrinsic nature, but this would have been at odds with allowing countries to set their own VAT rates.

MacRumours appear to be Mathematically challenged. If the apps are presently being taxed at 15 percent because they are sold out of Lux and the new rate is 20 percent because the end customer is in the UK.
Somehow that seems like a 5 percent increase to me.
Actually it would be a 4.3% increase on the VAT inclusive price.
