Adele has been hit with a £4 million (R85,682,395.96) tax bill for 2014, despite the fact she didn't perform or release any new music that year. The Hello singer returned from hiatus earlier this year with her new album 25, but is still paying off tax bills from 2014, despite the fact she didn't perform or release any new music in that year.However, as she was still earning royalties from her 2011 album 21 and her 2012 Bond song Skyfall, the 27-year-old star's firm Melted Stone Ltd. owes the money in corporation tax, according to the Daily Mirror newspaper.Adele has previously spoken out about having to pay so much tax, saying: "I use the NHS [National Health Service], I can't use public transport anymore. Most state schools are s**t, I've gotta give you, like, four million quid... are you having a laugh?"The Rolling in the Deep hitmaker is worth an estimated £50 million and her latest record - which was released in October - sold over 3 million copies in its first week.And Adele has admitted she still has five "really great" songs leftover from when she was writing the album.She said previously: "There are definitely four or five other songs that I would definitely revisit. We didn't finish it in time and also it just felt like maybe I should be like, 32, when I do it rather than 27?"..
