Understanding your payslip
Are you confused by payslip jargon and abbreviations? Use this interactive tool to help you understand what your payslip means.
NI Categories: Managing Employer Contributions
These categories are vital for your "Value Center" because they indicate the Employer National Insurance costs (the 15% rate for 2026/27). Selecting the wrong category can lead to significant overpayments or arrears.
Centralising Payroll
Centralising payroll and consolidating multiple school PAYE schemes into a single Multi-Academy Trust (MAT) scheme reduces administrative overhead, improves reporting accuracy, and simplifies compliance.
Managing Payroll Corrections for Leavers
Correcting employee pay, deductions, or leaving details after a staff member has departed requires specific handling under HMRC’s Real Time Information (RTI) rules.
Employment Allowance
The Employment Allowance (EA) enables eligible UK employers to reduce their Class 1 National Insurance (NI) liabilities by up to £10,500 per tax year.
HMRC Authentication Failure
When filing Real Time Information (RTI) submissions—such as a Full Payment Submission (FPS) or Employer Payment Summary (EPS) an Authentication Failure error indicates that HMRC's gateway has rejected the login credentials or employer registration details submitted by your payroll software.
Understanding Income Tax and National Insurance Calculations
Managing payroll under HMRC’s Pay As You Earn (PAYE) system requires a clear understanding of how statutory deductions are applied. Tax and National Insurance (NI) liabilities are calculated on each payslip based on gross pay, tax codes, National Insurance categories, and employee status.
Correcting Payroll Filed to HMRC
When errors occur on filed Real Time Information (RTI) submissions, HMRC guidelines specify clear methods for submitting corrections.
Editing or Unfiling Prior Tax Year Payroll Records
When managing historical payroll data, situations may arise where internal records must be adjusted or unfiled—such as when correcting records that were previously processed or filed outside of your main system.
The Difference Between RTI, FPS, and EPS
Under HMRC’s Real Time Information (RTI) framework, UK employers must send payroll data electronically to HMRC every time staff are paid, rather than filing a single report at the end of the tax year.
HMRC RTI Payroll Error Codes: Causes & Resolutions
When submitting Real Time Information (RTI) returns—such as Full Payment Submissions (FPS) or Employer Payment Summary (EPS) filings—HMRC's gateway may reject the data submission and return a specific error code or message.
Filing Missing Payroll Submissions After Tax Year-End (Post-19th April)
Under HMRC’s Real Time Information (RTI) regulations, the standard tax year closes on 5th April, and all year-end payroll filings—including Month 12 submissions—should ideally be completed by 19th April.
Location Onboarding & Transition Guide
There is no need to manually add location or employee data. Once your MAT is created, simply use our 'Importer' tool equipped with 'Smart Check'.
