Hi, I had worked as a locum medical consultant back in 2010 and filled my tax return at the time. In March 2011 I started working as an NHS consultant (PAYE paid) and moved home. Lst time I completed my tax return and paid was in December 2011 (for year 2010-2011) and then stopped completing tax returns as I am now employed by NHS and no longer self employed. Yesterday I received a letter from HMRC with penalty(1200.00 GBP) for late tax return for year 2012-2013! Any advice please?
