I have omitted to claim high rate tax relief for my company pension payments for the last 4 years, because I was originally under the impression that this would be handled automatically. I have in recent years completed my tax returns online. Can I claim retrospectively online, or do I need to ask them for a form, and if so is there a special form you have to complete? An email question to Revenue £ Customs was filtered out by their "it's too hard" software, and I was told to phone my local tax office.
Rather than sit at the end of a phone for an hour listening to music, does anybody here know how to go about this please? Any help greatly appreciated.
