The 31 January deadline for 2012/13 personal tax returns has passed, however please do not put your tax affairs aside for another year.
HMRC have already begun issuing PAYE coding notices in respect of 2014/15 and this is one area where people are often caught out.
Tax advisers are no longer sent copies of your tax codes. Therefore when you receive these please check to ensure they are correct and seek advice if you are unsure about anything.
A mistake on your tax code could mean that not enough tax is deducted during the year and you instead face a nasty tax bill when you submit your return.
