Service issues
Where a cash accounting method is held, and customers make a claim for Annual Investment Allowance in-year, they will not be able to view their estimated tax calculation in their software and HMRC online services.
We are working to correct this. In the meantime, your annual investment allowance submission can be deleted to allow the estimated calculations to be produced, and re-entered once we have made an update or before you file your tax return.
