HMRC's computer isn't always correct
HM Revenue and Customs have acknowledged that their software and some commercial software used by accountants doesn’t always come up with the right amount of tax payable! You may have seen this reported in some newspapers such as the Daily Telegraph.
This arises because the tax system of different income tax personal allowances, dividend allowances, savings rates has become more complicated rather than getting simpler!
These anomalies only arise in certain limited circumstances depending on the combination of dividends, interest and other income and we can assure you that we will check that our software calculates the correct amount of your tax. We will ensure that where the HMRC computer system comes up with a different figure any anomalies are resolved.
