I worked for a private company from 01 September 2010 until 23 June 2011. I have just received a mail enclosing my EMPLOYEE INCOME TAX CERTIFICATE [IRP5/IT3(a)] from my previous employer. She mentioned on this certificate that I worked from 01 September 2010 until 28 February 2011, which is not correct. I would like to know how will this affect me?

Kind regards
