QuickBooks Online with MTD no longer shows its own tax calculations!

I have moved from QuickBooks Self Employed to QuickBooks Online, and successfully connected to MTD, and submitted my Q1 report. But now QuickBooks Online no longer shows any of its own tax calculations.

I couldn’t access my 2025/26 self assessment summary, for my tax return, until a very helpful Kurt, from QuickBooks UK support, arranged for temporary access to my old QuickBooks Self Employed. QuickBooks online shows £0 tax due for that tax year even though all my invoices and expenses are there - presumably because it’s not a MTD year.

The problem I now have is that QuickBooks Online doesn’t show how much tax I owe so far this tax year! It shows how much from MTD Q1 but that’s only up to 5th July so well out of date. I’m having to use a spreadsheet to work out how much money I need to set aside for my tax bill which is a bit silly!
