I have just about finished my tax return and i think I have already paid on account more than I owe. So what do I do? I have tried to phone the tax office, no answer. EMailed and they say because my question is specific I need to contact the office. SHall I just file it and let them tell me? It says I have a payment due by Jan; some bloke I have already spoken to says I need to take off what I have already paid, it doesn;t do it automatically for you. So do I~ have to npay and then wait for a refund? SEems ridiculous. THank you in advance for any advice!
