Work out your take-home pay
Income tax, National Insurance and net pay for any UK salary, 2026-27.
An employer who fails to comply with a court attachment of earnings order can be fined up to £1,000 for each failure [1]. When a Direct Earnings Attachment arrives from the Department for Work and Pensions, the employer must start deducting without any involvement from a court at all [2]. These two facts sit at the heart of one of the least understood parts of running a UK payroll.
Court order deductions turn the employer into an unpaid collection agent for a debt that has nothing to do with the employment. The instruction can come from a civil court, a magistrates' court, a local authority or a government department, and each route carries its own rules on how much to take, what the employee must be left with, and when the money is due. Getting the arithmetic wrong exposes the business to liability for the shortfall, not the employee.
This guide sets out the main types of order a UK employer will receive, how the deduction is calculated in each case, the priority rules that decide which order is paid first, and the practical steps a payroll team should take from the moment an order lands in the post.
Key takeaways
- Court order deductions are legally enforced instructions to divert part of an employee's pay to a third party, and the employer carries the compliance risk, not the employee.
- The four common orders are the civil court Attachment of Earnings Order, the Council Tax Attachment of Earnings Order, the DWP Direct Earnings Attachment, and the Child Maintenance Service Deduction from Earnings Order.
- Most orders protect a floor of the employee's net pay, and the child maintenance protected earnings proportion is fixed at 60% of net earnings.
- The employer may deduct £1 from the employee's pay towards administrative costs each time a deduction is made under most order types.
- Failing to operate a court Attachment of Earnings Order correctly can lead to a fine of up to £1,000 per breach.
What a court order deduction actually is
A court order deduction is a legally binding instruction requiring an employer to withhold a set amount from an employee's earnings and pass it to a named creditor. The debt being collected is personal to the employee, common examples being unpaid council tax, a county court judgment, a magistrates' court fine or child maintenance arrears. The employer is a third party to that debt, drawn in only because it controls the flow of the employee's wages.
The instruction overrides the ordinary rule that an employer needs written consent before deducting from pay. Deductions required or authorised by statute, which includes court attachment orders, statutory student loan deductions and government-issued attachments, are lawful without the worker agreeing to them [3]. That is why an order can be enforced even where the employee objects, provided the employer follows the calculation and payment rules attached to it.
Every order names three things the payroll team needs: the total debt to be collected, the method of calculation, and the creditor to be paid. Some orders also set a protected earnings figure, a floor below which the employee's pay must not fall. Handling these correctly is a core part of day to day UK payroll software operation, and modern systems apply the tables automatically once the order type is recorded.
The main types of order an employer will receive
Four instruments account for the overwhelming majority of court order deductions operated through UK payroll. They look similar on paper but follow different legislation and different sums.
Attachment of Earnings Orders from the civil courts
An Attachment of Earnings Order (AEO) is issued by a county court or a magistrates' court to recover a judgment debt, a fine or maintenance that has fallen into arrears [1]. The order tells the employer a normal deduction rate, the regular amount to take, and a protected earnings rate, the amount the employee must be left with after the deduction [4].
The employer must comply with the order within the timescale it states and must notify the court if the named person does not work for them or later leaves [1]. Failure to do either can result in a fine, which makes the initial administrative response as important as the ongoing deduction [4].
Council Tax Attachment of Earnings Orders
A Council Tax Attachment of Earnings Order (CTAEO) is issued by a local authority, not a court hearing, to recover unpaid council tax after a liability order has been granted. Unlike a civil AEO, the deduction is calculated from fixed percentage tables set in regulations, and there is no separate protected earnings rate for the employer to apply [5]. The percentage simply rises with the size of the pay packet.
The local authority can run a CTAEO alongside other orders, and a second CTAEO on the same employee is calculated differently from the first [5]. The employer may take £1 for administrative costs on each pay day a deduction is made, in addition to the amount sent to the council [6].
Direct Earnings Attachments from the DWP
A Direct Earnings Attachment (DEA) is not a court order at all. The Department for Work and Pensions can instruct an employer to make a DEA deduction to recover a benefit overpayment or a Social Fund loan without going through a court [2]. The employer is legally required to operate it in the same way as a court order.
A DEA is calculated from percentage tables applied to net earnings, using either a standard rate or a higher rate depending on the notice [2]. The employer must make the deduction and pay it to the DWP by the 19th of the month following the deduction, and may take £1 per deduction for administration [6].
Deduction from Earnings Orders for child maintenance
A Deduction from Earnings Order (DEO) is issued by the Child Maintenance Service to collect ongoing child maintenance or arrears directly from a paying parent's wages [7]. The order states a normal deduction rate and relies on a fixed protected earnings proportion set at 60% of net earnings [7].
The employer must apply the deduction from the employee's net pay and send it to the Child Maintenance Service, again with an optional £1 per deduction for costs [7]. Because child maintenance is treated as a priority, it takes precedence over most other non-priority deductions when several orders are in force [8].
Priority and non-priority orders, and the order of deduction
When an employee is subject to more than one order, the employer cannot simply take them in the sequence they arrived. Orders are ranked as priority or non-priority, and that ranking dictates which is satisfied first from the available pay.
Priority orders include maintenance orders, fines and most attachments made under the maintenance and fines rules, while non-priority orders are typically civil judgment debts [1]. Priority orders are worked out and deducted first, and only the pay remaining afterwards is available for any non-priority order [4].
The distinction also governs what happens when there is not enough pay to satisfy an order in full. For a priority order, the unpaid balance is carried forward and made up on the next available pay day, whereas for a non-priority order the shortfall is disregarded and never carried over [1]. A DEA sits alongside this framework and must not be taken where a court order already reduces earnings below the DEA protected level [2].
The table below summarises how the four common orders behave.
| Order type | Issued by | Calculation basis | Protected earnings | £1 admin allowed |
|---|---|---|---|---|
| Civil Attachment of Earnings Order | County or magistrates' court | Normal deduction rate set by court | Yes, protected earnings rate set by court | Varies by order |
| Council Tax AEO | Local authority | Fixed percentage tables | No | Yes |
| Direct Earnings Attachment | DWP | Standard or higher percentage tables | Yes, 60% of net earnings retained | Yes |
| Child maintenance DEO | Child Maintenance Service | Normal deduction rate | Yes, 60% protected earnings proportion | Yes |
How much can be deducted
The sum an employer withholds depends entirely on the order type. Percentage-based orders climb in bands with earnings, while court-set orders name a fixed figure. Understanding the tables prevents both over-deduction, which harms the employee, and under-deduction, which exposes the employer.
DEA standard and higher rate tables
A DEA applies a percentage of net earnings that rises through defined bands. The standard rate reaches a maximum of 20% and the higher rate, used mainly where an overpayment involved fraud, reaches 40% [2]. No deduction is made where monthly net earnings fall at or below £430, equivalent to £100 a week [2].
The monthly bands are set out below [6].
| Monthly net earnings | Standard rate | Higher rate |
|---|---|---|
| Up to £430 | Nil | Nil |
| £430.01 to £690 | 3% | 6% |
| £690.01 to £950 | 5% | 10% |
| £950.01 to £1,160 | 7% | 14% |
| £1,160.01 to £1,615 | 11% | 22% |
| £1,615.01 to £2,240 | 15% | 30% |
| Over £2,240 | 20% | 40% |
Council tax deduction tables
A CTAEO uses its own statutory tables, which differ from the DEA figures and carry no protected earnings floor. The monthly table below shows how the percentage steps up with pay, with the top band splitting the calculation between a capped rate and a marginal rate [5].
| Monthly net earnings | Deduction |
|---|---|
| Up to £300 | Nil |
| £300.01 to £550 | 3% |
| £550.01 to £740 | 5% |
| £740.01 to £900 | 7% |
| £900.01 to £1,420 | 12% |
| £1,420.01 to £2,020 | 17% |
| Over £2,020 | 17% on the first £2,020, then 50% on the remainder |
Because a CTAEO ignores protected earnings, a high earner can see a substantial portion of pay above £2,020 diverted to the council [5]. Payroll teams running this manually should double check the marginal 50% band, which is a frequent source of error [6].
Protected earnings and the 60% rule
Most orders, the CTAEO aside, guarantee the employee a minimum share of net pay. For a DEA, the combined total of the DEA and any other deductions must never leave the employee with less than 60% of net earnings, and any part of the DEA that would breach this is not taken [2]. The same 60% proportion applies to a child maintenance DEO, so the paying parent always retains at least 60% of their net wage [7].
Where earnings are too low to take the full instructed amount, the employer deducts as much as the protected floor allows and no more [7]. The £1 administrative charge is treated separately: an employer may take it even if doing so dips the employee below the protected earnings rate, provided the payment does not fall below the National Minimum Wage [1]. Confirming the National Minimum Wage position is essential, and the current rates are published by HMRC [9].
The employer's step-by-step obligations
Operating an order well is less about the arithmetic, which software handles, and more about the sequence of actions around it. Three moments matter most: receiving the order, running each deduction, and closing the order out.
When a new order arrives
The first task is to identify the named employee and confirm they are on the payroll. If the person does not work for the business, the employer must tell the issuing body promptly, and for a court AEO that notification is a legal requirement carrying a penalty if missed [1]. For a DEA, the employer should confirm receipt to the DWP and begin deductions from the first pay day that falls after a set number of days from the notice date [2].
The order type, reference numbers and creditor details should be recorded against the employee before the next payrun, so the deduction applies automatically. Bureaux handling this across many clients typically rely on payroll bureau software that stores the order and flags it on every relevant pay period [6].
Running the deduction each pay period
Each pay day, the employer calculates the deduction on the correct earnings base, applies any protected earnings floor, and takes the optional £1 for costs [7]. The amount withheld must appear on the payslip as a separate line so the employee can see the deduction and its purpose, a payslip requirement that applies to every worker [3].
The collected money must then reach the creditor by the stated deadline. A DEA payment is due to the DWP by the 19th of the month after deduction, and a similar discipline applies to council and Child Maintenance Service payments [6]. Late payover, not just late deduction, is a compliance failure [2].
When the employee leaves or earnings are too low
When an employee subject to an order leaves, the employer must notify the issuing body so the order can be redirected or paused [1]. For a DEA, the employer tells the DWP that the person has left and stops the deduction [2].
If earnings in a given period are too low to allow any deduction, the employer records a nil deduction and, for a priority order, carries the shortfall forward to be recovered later [1]. A missed deduction is not written off unless the order type specifically disregards it, which is why the priority classification has to be right from the outset [4]. Employers embedding these rules into their own systems often use an HMRC-recognised payroll API so the carry-forward logic runs consistently across every client [7].
Penalties for getting it wrong
The financial risk of a mishandled order falls on the employer. For a civil Attachment of Earnings Order, an employer who fails to comply, or who fails to notify the court that the employee has left, can be fined up to £1,000 for each failure [1]. The penalty is per breach, so repeated errors compound quickly.
For a DEA, an employer who does not operate the attachment correctly can become liable for the sums that should have been deducted, effectively paying the employee's debt out of the business [2]. The same exposure applies where deductions are taken but not passed on to the DWP by the deadline [6]. Accuracy and timeliness are therefore not administrative niceties but the difference between compliance and an avoidable bill.
Work out net earnings before applying an order
Because a DEA and a DEO are both calculated on net earnings, an employer needs a reliable net pay figure before any order percentage is applied. The Moonworkers UK salary calculator works out take-home pay under the current PAYE and National Insurance rules, giving the net base from which each deduction band is measured.

About this calculator
This calculator gives you a close estimate of your UK payroll deductions for 2026-27, using HMRC's exact percentage method. It covers the vast majority of employees on standard tax codes, but it won't match your payslip to the penny in every case. Edge cases it does not cover include in-year tax code changes, K-code carry-forwards, Week 53 adjustments, payrolled benefits in kind, and multi-employment NI deferral. Powered by the same engine as the Moonworkers Payroll API.
Frequently asked questions
Why might the result differ from my payslip?
This calculator uses your current gross pay and tax code to produce an estimate. Your employer may apply adjustments not covered here, such as mid-year tax code changes, K-code carry-forwards, or benefits in kind processed through payroll. For most employees on a standard tax code these differences are negligible.
What tax code should I enter?
Use the tax code shown on your most recent payslip or the PAYE Coding Notice (P2) from HMRC. If you're not sure, 1257L is the standard code for most employees resident in England, Wales, or Northern Ireland. Use S1257L for Scotland or C1257L for Wales if you pay Scottish or Welsh income tax.
Which NI category applies to me?
Most employees use Category A. Use M if you are under 21, H if you are an apprentice under 25, or C if you are over State Pension age. Your employer is responsible for assigning the correct category — if in doubt, check your payslip.
Which student loan plan am I on?
Your plan depends on when and where you studied. Plan 1 covers students who started before September 2012. Plan 2 is for English and Welsh students who started from September 2012 to July 2023. Plan 5 applies to English students who started from August 2023. Plan 4 covers Scottish students. You can check your plan at gov.uk or on your payslip.
What is the YTD cumulative PAYE mode?
HMRC's standard method calculates income tax on your total earnings to date each period, then subtracts tax already paid. If you're mid-year and want to see exactly what tax should be deducted in a specific period, expand the Year-to-date section and enter your running totals from previous periods only.
Conclusion
Court order deductions convert the payroll function into an enforcement channel for debts the business had no part in creating, and the legislation places the compliance burden squarely on the employer. The four common instruments, the civil AEO, the CTAEO, the DEA and the child maintenance DEO, each carry a distinct calculation, a distinct treatment of protected earnings, and a distinct penalty for error, which is why treating them as interchangeable is the root of most mistakes.
The safest position combines two things: an accurate, up to date understanding of the order type in front of the payroll team, and a system that applies the correct table, protects the right earnings floor, and pays the creditor on time. As enforcement bodies increasingly issue attachments without a court hearing, the volume of orders reaching UK employers is likely to keep rising, and the businesses that handle them cleanly will be those that have automated the rules rather than reworking them by hand each month.
Frequently asked questions
Can an employer refuse to operate a court order deduction?
No. A deduction required by a court attachment order or a government-issued attachment is authorised by statute and does not need the employee's agreement, so the employer must operate it [3]. Refusing or failing to comply with a civil Attachment of Earnings Order can lead to a fine of up to £1,000 per failure [1].
How much can be taken from an employee's wages under a court order?
It depends on the order. A DEA takes a percentage of net earnings up to 20% at the standard rate or 40% at the higher rate, with nothing taken below £430 net a month [2]. A child maintenance DEO must always leave the paying parent with at least 60% of net earnings [7].
What is the £1 deduction on a payslip next to a court order?
Most orders let the employer keep £1 from the employee's pay each time a deduction is made, to cover the administrative cost of operating the order [6]. This £1 can be taken even if it dips the employee below their protected earnings rate, provided pay does not fall below the National Minimum Wage [1].
Which order comes first when an employee has several?
Priority orders such as maintenance and fines are deducted before non-priority civil debts, and only the pay left after the priority order is available for the rest [4]. Where a priority order cannot be paid in full, the shortfall is carried forward to the next pay day, while a non-priority shortfall is disregarded [1].
