Operating PAYE and Payroll Software

Your payroll software plays a key role in calculating and deducting the correct amounts for both Income Tax and National Insurance contributions. It factors in:

  • Employee tax codes.
  • Individual thresholds for PAYE and NICs.
  • Any adjustments required for changes in employee income or benefits.

Key Points for 2025

  • Tax-Free Allowance Adjustment: Ensure high-income employees are aware of reductions in their Personal Allowance as their income rises above £100,000.
  • Review Payroll Software: Verify that your payroll system is updated for the 2025–2026 tax thresholds and rates.
  • Stay Compliant: Regularly check for updates from HMRC to ensure your business adheres to the latest tax and NIC regulations.

Why Compliance Matters

Accurate PAYE and NIC deductions:

  • Prevent HMRC penalties for underpayment or non-compliance.
  • Build trust with employees through correct pay processing.
  • Streamline financial reporting for your business.
