“If you’re due a tax refund or need to pay more tax, HM Revenue and Customs (HMRC) may send you a P800 tax calculation.” You can find more information here.
The P800 is in the news this week as apparently there have been a few issued in error following on from HMRC errors. These errors are related to income tax, and people are advised to contact HMRC if they receive a notice related to the 2013/14 tax year.
Only a small proportion of P800s are affected by the error, and HMRC are sorry for any worry or inconvenience caused. The interesting thing with this story is that really RTI is supposed to be just that, Real Time Information. So in the press there is considerable speculation as to just how efficient HMRC is at handling the RTI submissions.
So for most people the P800 is far too dull to be concerned with, but if you are one of the unfortunate people to be issued a demand in error, I am sure it will become of the utmost importance and interest.
