Drowning in payroll paperwork? HMRC’s Real Time Information (RTI) rules make payroll mission-critical and unforgiving. For accounting firms, mistakes in RTI reporting mean penalties, frustrated clients, and wasted partner hours. The good news: modern payroll software turns RTI from risk into routine.

RTI in a Nutshell: Why ‘Real Time’ is Non-Negotiable

Since 2013, RTI requires employers to report payroll on or before each payday so HMRC has up-to-the-date visibility of PAYE, National Insurance and student loan deductions. The two submissions you rely on are:

  • Full Payment Submission (FPS): The detailed report for each pay period, covering employee earnings, deductions, and tax codes.
  • Employer Payment Summary (EPS): Used to report adjustments, reclaim statutory pay, claim the Employment Allowance, or crucially declare a ‘Nil’ payment if no one was paid.

Accurate RTI reporting is essential for correct PAYE and NIC collection and avoiding fines.

Common payroll pitfalls (and how automation fixes them)

  • Late or Missed Submissions: Often caused by forgotten deadlines or technical issues.
    Fix: Acting Office sends automated reminders and integrates directly with HMRC to guarantee FPS and EPS submissions are made on time.
  • Incorrect Employee Data: Mistakes in NI numbers, tax codes, or names can cause rejections.
    Fix: Acting Office validates all employee details during onboarding and flags errors before submission.
  • Skipping ‘Nil’ EPS Returns: A month without payroll still requires an EPS submission.
    Fix: Acting Office automatically generates and files EPS returns for months with no payroll activity, ensuring compliance.
  • Miscalculating Statutory Pay: Errors in SMP, SSP, and other statutory payments can be costly.
    Fix: Acting Office automates statutory pay calculations, ensuring accuracy and compliance.
