Users are currently experiencing tax calculation issues in IRIS
Resolution
17.3.1 is the latest version and this release fixes a number of HMRC calculation issues which HMRC updated on 23 October 2017. In most scenarios the tax calculation that IRIS generates will match the HMRC calculation, there are however some scenarios that the HMRC system will still not deal with correctly and there are warnings in IRIS Personal Tax to highlight these scenarios. If you are not running the latest release we would advise to upgrade to the latest version and then regenerate the tax calculation report. Where a return is rejected due to a HMRC exclusion the return would need to be sent by post with a reasonable excuse claim form. Please advise the customer to note the exclusion ID in the reasonable excuse claim form. HMRC reasonable excuse claim form If the return has not been rejected due to a HMRC exclusion, please send an extract and copy of the tax calculation to support@iris.co.uk for further investigation To take an extract of a client click Client | Extract | choose the folder where you want the extract to be saved to In most cases users believe that the IRIS calculation is overstating the tax liability, this can either be down to: a) User has incorrectly applied the allocation of income and allowances b) The calculation being covered by an Exclusion In most cases, and this will vary depending on types of income and allowances, but in most cases to work out how much of the personal allowance should be set against income in the basic rate band the calculation has to look at what is remaining in the basic rate band after all non-savings income is allocated to it to determine how much of the personal allowance should be set against savings income. If the return is covered by a HMRC exclusion please make reference to the latest HMRC exclusions document.
