Alright, so IE7 is a fair few years old now, maybe it’s time you move onto something a bit more modern perhaps? Well one Aussie company definitely thinks you should, and so are charging you for not having made the completely free and painless jump to a newer web browser.

Kogan.com have introduced the worlds first tax on Internet Explorer 7, charging folks who still use the archaic browser a ‘tax’ for the effort of keeping the site running in it.

Speaking to the BBC, chief executive of Kogan.com Ruslan Kogan said the measure was brought n to recoup the time and costs involved in “rendering the website into a antique browser.”

It seems that users will be charged 6.8% on all purchases with a 0.1% extra for every month since IE7 launched.

“The amount of work and effort involved in making our website look normal on IE7 equalled the combined time of designing for Chrome, Safari and Firefox,” explained Mr. Kogan.

He explained that around 3% of his consumers use IE7 and he doesn’t actually expect anyone to pay the tax, instead he is trying to encourage them to upgrade to a newer and safer browser.

Internet Explorer 10 is set to release in the Autumn, so IE7 is really rather old.
