The webinar agenda covers PAYE Modernisation, including an overview of the new legislation, how payroll software will handle the changes, and making corrections in real time. There will be a presentation from Revenue on the new rules. Key points include submitting payroll data to Revenue for each pay period through APIs for automated tax credit retrieval and submissions. Corrections can be made but consistent errors could result in penalties. Split payrolls may require separate employer numbers. The new emergency tax rules remove the first tier of credits.
