I've taken on a new limited company client - he has ran his own payroll and CIS scheme - I'm hoping for tips on how to unravel the mess he's got himself into:
2015/16 - no payroll - client reported most of the CIS deducted from subbies but not all and some in the wrong period. Also failed to report some CIS suffered. 1. What's the best way to report correct amounts? File late / amended CIS300 reports / EPS? Or can I file EYU (not sure if that is only for PAYE and not CIS)?
2016/17 - director only on payroll and has paid some tax and NI - almost all monthly payroll submissions are wrong. Seemingly not submitted from Xero as planned. Again several of the CIS300's reported are wrong value / wrong period.
2. Shall I submit correct FPS's for each payroll month? Will this result in several penalties?
3. Shall I submit just one additional FPS with correct YTD payroll values?
4. And if I submit corrected CIS300's will the corrected values over-write HMRC's incorrect values? Will multiple penalties be issued?
There are currently lots of estimated PAYE demands showing on the online PAYE account. Client has paid most demands as they arrived believing he was keeping everything up to date.
Thanks, any tip appreciated.
