Many people across the United Kingdom stop and wonder what a line named Co-payment on My Wage Slip actually means. Whether you work in Manchester near the Trafford Centre, in London close to Canary Wharf, in Birmingham by the Bullring, or in Glasgow near George Square, this small word can create confusion. This article explains it clearly so every worker can understand what it means, why it appears, and how it affects take home pay. It is written with real workplace experience and uses guidance trusted by employers across the UK including insights shared by Replacement Payslips Plus.
What Is A Co Payment On A Wage Slip
First, let’s be clear. You are right to be confused. If you search for “co-payment” online, you will find it means a small fee you pay for an insurance claim, usually for health. This is why it feels so out of place on your salary statement.
In the United Kingdom, our pay is handled through the PAYE (Pay As You Earn) system. This means your employer deducts money for tax and other things before you get your final net pay. These deductions have official names. The problem is, sometimes a payroll software might use an unusual or non-standard word for one of these. That “co-payment” is almost certainly one of the common deductions below, just with a strange label.
Why a Co-Payment Appears on Your UK Wage Slip
Many employees are surprised to see a co-payment listed on their wage slip and often assume it should fall under tax or National Insurance. In most cases, a co-payment is a voluntary deduction linked to a benefit or scheme you’ve chosen to take part in. Because it isn’t a government-mandated deduction, it appears separately on your payslip.
A proper UK wage slip must clearly itemise every deduction so you always understand where your earnings are going. Payroll transparency is a legal requirement, whether you work in London near London Bridge, in Edinburgh close to the Castle, around Cardiff Bay, or in central Belfast. No matter the location, the format and clarity of wage slips must follow the same national payroll standards.
The Most Likely Culprit: Your Workplace Pension
This is the number one suspect. A workplace pension is now a legal requirement for most employees in the UK thanks to auto-enrolment.
Here is how it works:
- You pay a percentage of your pay into a pension pot.
- Your employer also pays money in.
- The government often adds to it with tax relief.
Think about that. You are “paying” and your employer is “co-paying” with you. It is a joint payment. It is very likely that your payroll department has simply labelled your pension contribution as a “co-payment” on your wage slip. This is especially common if your employer has a specific company pension scheme. You can check this by looking at your employment contract or the papers you received when you first started your job.
Other Common Deductions It Might Be
If it is not your pension, it will be one of these standard UK deductions. Your mission is to match the amount on your payslip to one of these.
Income Tax (PAYE)
This is the most obvious deduction. This is the money you pay to the government (via HMRC) to fund public services like the NHS, roads, and schools. Whether you are working near The Shard in London or the Angel of the North in Gateshead, everyone pays this. It is calculated based on your tax code and how much you earn. On your payslip, it will usually be labelled “Income Tax” or “PAYE“.
National Insurance (NI)
This is another non-negotiable deduction. Your National Insurance contributions pay for state benefits, like the State Pension, Jobseeker’s Allowance, and the NHS. It is usually labelled “NI”, “NIC“, or “National Insurance”. The amount you pay depends on your earnings.
Student Loan Repayments
If you went to university, this is a very common deduction. Repayments for your student loan are taken directly from your pay once you earn over a certain amount. This could be labelled “Student Loan” or just “SL”.
What About Salary Sacrifice Schemes?
This is another strong possibility. A salary sacrifice is when you agree to give up part of your salary in exchange for a non-cash benefit. Because you are “paying” for a benefit, the system might call it a “co-payment”.
Common examples include:
- Cycle to Work Scheme: You get a new bike, and the cost is deducted from your pay each month.
- Childcare Vouchers: You “buy” vouchers from your pre-tax salary to pay for childcare.
- Company Car Schemes: Part of your salary is taken to cover the cost of the car.
- Private Health Insurance: Your company might offer health insurance, but you have to contribute (or “co-pay”) a portion of the monthly cost. This is one of the few times the word “co-payment” is used correctly in a UK benefits context.
If you signed up for any of these, you have found your answer. Check any agreements you signed when you joined the scheme.
The Serious Possibilities: What is an AEO?
This is much rarer, so please do not panic. But it is important to know about. An Attachment of Earnings Order (AEO) is a court order that can be sent to your employer. It instructs them to deduct money directly from your wages to pay off a debt you have, such as council tax arrears or child maintenance.
This is a very serious deduction. However, you would almost certainly know about this before it appeared on your payslip. You would have received many letters and official court documents. It is highly unlikely to be labelled “co-payment”. It is usually clearly marked as “AEO” or “Attachment of Earnings”.
How to Check Your Payslip and P60
The best way to solve this mystery is to do some simple checks.
- Gross Pay vs. Net Pay: Look at your Gross Pay (the total amount you earned before any deductions) and your Net Pay (the amount that lands in your bank). All the deductions, including the “co-payment”, are the difference between these two.
- Check Your Tax Code: Your tax code (like 1257L) tells your employer how much tax to deduct. You can find this on your payslip. If this code is wrong, you could be paying too much or too little tax.
- Review Your P60: At the end of every tax year (which ends on 5th April), your employer must give you a P60. This is a summary of your total pay and all the deductions you have made for the whole year. Many companies now provide your P60 Online through a payroll portal. This document is very important for checking if your pension and tax payments are correct.
Whether you work for the NHS in Leeds or a tech company near Manchester’s MediaCityUK, the rules are the same. Your employer is legally required to provide you with a payslip that clearly shows all deductions.

FAQs
What is the difference between gross pay and net pay?
Your gross pay is your total salary before any deductions like tax, National Insurance, or pension are taken out. Your net pay is the final “take-home” amount that you actually receive in your bank account.
Why has my tax code changed?
Your tax code can change if your personal circumstances change. This could be because you started a new job, have a second job, started receiving a pension, or have company benefits. HMRC will usually send you a letter to explain the change.
Who do I ask about a mistake on my payslip?
Your first point of contact is always your payroll department or your line manager. They have access to the system and can explain exactly what each deduction is for. Do not be afraid to ask; it is your money and you have a right to understand.
What does PAYE mean on my wage slip?
PAYE stands for “Pay As You Earn”. It is not a separate tax, but the name of the HMRC system used to collect Income Tax and National Insurance contributions directly from your salary.
