HMRC Payroll Updates: Final Deadlines for 2025/26 P11D and Class 1A National Insurance

Navigating the 2025/26 P11D and Class 1A Filing Deadlines

As we progress through the summer, it is essential for employers to ensure their year-end reporting for the 2025/26 tax year is finalised. HMRC has confirmed that the deadline for submitting P11D forms and P11D(b) returns for the previous tax year is 6 July 2026. If you have not yet completed these filings, it is imperative to act immediately to avoid potential penalties. Our managed payroll service at sterlingpayrollsolutions.co.uk/services ensures you stay ahead of every HMRC deadline, allowing you to focus on your core business activities while we handle the regulatory complexities.

Understanding Class 1A National Insurance Payments

Beyond the filing deadline for returns, employers must also ensure that any Class 1A National Insurance contributions are paid to HMRC in a timely manner. The deadline for these payments depends on your chosen method of settlement. If you are paying by cheque, the funds must reach HMRC by 19 July 2026. For those paying electronically, the deadline is 22 July 2026. Missing these dates can trigger interest charges and penalties, which is why accurate and early preparation is vital for every organisation.

The Shift Toward Real-Time Reporting

While the current P11D process remains the standard for the 2025/26 tax year, HMRC is actively preparing the payroll industry for a digital transition. Mandatory payrolling of benefits in kind is currently scheduled for a phased rollout, with specific benefits such as company cars and medical insurance prioritised for the 2027/28 tax year. We recommend that businesses review their current benefit schemes now to determine how these future changes will affect their internal systems. If you require professional guidance on transitioning to payrolling or need assistance with your current obligations, book a free consultation with our Exeter payroll bureau at sterlingpayrollsolutions.co.uk/book.
