Thank you so much Davinia,

So there is a minimum of 19 people on the payroll (changes month to month) so no need to use basic tools.

I started at current year and zeroed out all hours from M1 to month 11, submitting an FPS for each month as I went and then submitted an EPS saying its the last of the year. I then did the same for 22/23 tax year. The FPS in M11 23/24 showed no current tax liabilities and no cumulative tax liabilities.

Will I need to redo 23/24 as I didn't start with 22/23?

Thanks for your patience, I've been given so many wrong solutions by HMRC and QB over the last few months, its driving me mad!
