NHS Exemption Thresholds....

I have been given a link / print off of the NHS Exemption threshold figures from my welfare officer

Tax Credits are claiming it is £15, 276

But on the link

that all staff are supposed to use it states

2003-2004 - £14,200
2004-2005 - £14,600
2005-2006 - £15,050
2006-2007 - £15,050

2008-2009 - £15,050
2009-2010 - £15,276

2011-2012 - £15,276
