Just wondering if there is any limit on this. Will be putting in for 2009 this week just wonder can I then out in for 2010 in January. I'm PAYE and this is mainly medical, refuse charges etc?
Once you have received your P60 (probably about mid January) you can claim any refunds due for 2010. Reminder!! Many people forget to check if flat rate expenses apply to them
As long as you make a claim for a refund of PAYE within 4 years, then you have plenty of time. As Black Sheep said, once you receive your P60 in Jan/Feb, you can file your return straight away
