For over 2 years the company have written and phoned to tell HMRC that they have NOT overpaid nearly £60k. HMRC will not accept this and still insist that the company have overpaid. I have traced it all back and found out how it happened and explained it but to no avail.
Bearing this in mind, another client, when I have looked at the annual summary, shows that they have overpaid by nearly £10k. I have written and told them that the two months where HMRC say they have overpaid are correctly submitted and accord with the RTI returns.
dont know what else to do
