Self assessment error or mistake or unable to provide paperwork to support an expense?
Income tax penalties may apply. The rate at which the penalty applies ranges from 0% - 100% and is based broadly on 2 factors.
- Who found the error. If it is HMRC, the starting point for the penalty rate will be higher. If you volunteer the information, the penalties could be as low as 0%.
- The reason for the error. There are 3 buckets ranging from i) Not-deliberate ii) deliberate iii) deliberate and concealed. A lower penalty applies for (i) and a higher rate applies for (iii). The burden of proof sits with HMRC and is quite high. As an example, adding an extra 0 in an expense on your tax return may be considered not-deliberate but selling a property and moving the funds into a relatives account overseas could be considered deliberate and concealed.
