Confused over CTC

[lisacaton1980]

Hi, I was made redundant in May 2013 and have only just found new employment. I was on JSA for 6 months so advised HMRC about my change in income etc.

I've just been working the figures out so I can update them with my new income and I think I may have made my original estimate £4k lower than it is actually going to be. (Due to me being unemployed my OH worked very long hours so has earned more money).

Is it likely that we will have to pay some money back? We weren't being awarded any CTC until I was made redundant and have received £20p/w

Thanks
