How do you start a new financial year? I'm trying to file 2018/19 then start 2019/20, any help much appreciated thank you

Hello and welcome to Community tighnacollie,

Can I please confirm whether any filings have been recorded in the QuickBooks Online account? The start of the financial year can be set in the VAT settings under the taxes heading, this is also where you are able to set up MTD with HMRC.
