DD is almost 5 and she has to make her bed every morning, empty her lunchbox after school and set the table each night for dinner plus helping out with tidying up etc. She doesn't get pocket money, but if she doesn't do all her jobs, she loses a fridge magnet (lots of fridge magnets equal a little pressie). If you google The Organised Housewife, she has a post the with a whole list of 'responsibilities' that kids of various ages can do.
