Employers’ NICs Calculator

TAX YEAR 2025 - 2026

From April 2025, changes to Employers’ National Insurance take effect. If you’re unsure what the 2024 Autumn Budget means for your payroll, our NI calculator will help. Enter a salary, the NI category letter and any salary-sacrifice pension to see your estimated employer NIC under the new rules and how it compares with 2024/25.

Not sure which category to choose? Category A is the most common starting point; your payroll records will confirm the correct letter.

Looking to manage costs? Apprentices may fall under category H, where employer NICs aren’t due up to the relevant threshold.

We’re here to help—use the calculator for guidance and contact us for advice tailored to your business.
