You will not receive a P60 from your employer for 2019 or subsequent years.
Instead, from 1 January 2020 you will have access to an Employment Detail Summary in myAccount. It is accessible through the ‘Review your tax’ link in PAYE Services.
This summary contains your pay and statutory deductions for the year as reported by your employer or pension provider. You can create a document to view or print if required. The document can be used as proof of income where required by third parties.
