ours is usually fairly significant as DH has a lot he can claim due to the type of work he does. thankfully, his bosses are able to pay him part of his income at a rate that has the tax left off anyway (his living away from home allowance is tax free so they pay it tax free during the year - if not, that alone would be almost 14k he is able to claim) - most years he gets back around 5k, mine is around 2k. might be more this year though
