A deduction from earnings order can require an employer to hand over part of an employee's pay every payday, and the penalty for getting it wrong is steep: a fine of up to £500 for each missed payment and up to £1,000 for failing to supply information the Child Maintenance Service asks for ([1]). The deduction must also leave the employee with at least 60% of their net earnings, a protected floor set in law ([2]).
For the payroll team, a deduction from earnings order (usually shortened to DEO) is not optional and not negotiable. It arrives as a formal instruction, it names a paying parent already on the payroll, and it sets out the amount to collect. The employer becomes an unpaid collection agent for the state, with legal duties attached.
This guide explains what a DEO is, how it differs from the other earnings orders a UK employer might receive, exactly how to calculate the deduction against the protected earnings floor, what counts as earnings, when payments are due, and what happens when the pay packet is too small to cover the full amount.
Key takeaways
- A deduction from earnings order collects child maintenance directly from a paying parent's wages or pension, issued by the Child Maintenance Service.
- Every deduction must leave the employee with at least 60% of their net earnings, known as protected earnings.
- Net earnings for a DEO means pay after Income Tax, Class 1 National Insurance and pension contributions.
- Employers must send each deduction to the Child Maintenance Service by the 19th day of the month after the deduction was made.
- An employer can keep an extra £1 per deduction towards administrative costs, and faces fines of up to £500 per missed payment.
- A DEO is one of several earnings orders, and the rules on priority decide which is applied first when more than one lands on the same employee.
What a deduction from earnings order is
A deduction from earnings order is a way for the Child Maintenance Service to collect child maintenance directly from a paying parent's earnings or pension, rather than relying on that parent to pay voluntarily ([3]). The paying parent is the parent who does not have main day-to-day care of the child. The employer sits in the middle, instructed to deduct the money and forward it.
Child maintenance itself is calculated by the Child Maintenance Service using the paying parent's gross weekly income. Under the basic rate, a paying parent pays 12% of gross weekly income for one child, 16% for two children and 19% for three or more ([4]). The service can take into account gross weekly income up to a ceiling of £3,000; above that, the receiving parent must apply to court for any additional sum ([5]). The employer never calculates the maintenance figure. That work is done before the DEO arrives, and the order simply states the amount to collect.
When an employer receives a DEO
An employer is sent a deduction from earnings order when an employee who is a paying parent falls into one of several situations: the parent chooses to pay maintenance directly from earnings, does not already pay maintenance they owe, pays the wrong amount, or pays late ([6]). In every case the trigger sits with the employee and the Child Maintenance Service, not with the employer.
Once the order lands, the employer's obligations begin immediately. There is no grace period to decide whether to comply, and no route to challenge the underlying maintenance assessment through payroll. Any dispute about the amount is a matter between the paying parent and the Child Maintenance Service, and the employer must keep deducting while that runs its course ([7]). Handling these instructions accurately is part of what any HMRC-recognised payroll software for SMEs should support out of the box.
DEO, AEO and DEA: three different orders
Payroll teams often use "attachment" and "deduction" loosely, but the UK operates several distinct earnings orders, each with its own rules. A DEO comes from the Child Maintenance Service for child maintenance. An attachment of earnings order (AEO) is issued by a court for debts such as unpaid fines or county court judgments ([8]). A direct earnings attachment (DEA) is issued by the Department for Work and Pensions to recover benefit overpayments without going through the courts at all ([9]).
The table below sets out the core differences an employer needs to keep straight.
| Order | Issued by | Recovers | Protected earnings |
|---|---|---|---|
| Deduction from earnings order (DEO) | Child Maintenance Service | Child maintenance | 60% of net earnings ([[10]](https://www.gov.uk/child-maintenance-for-employers/how-to-make-deductions)) |
| Attachment of earnings order (AEO) | Court (England, Wales, Northern Ireland) | Fines, county court judgment debts | Protected earnings rate stated in the order ([[11]](https://www.gov.uk/debt-deductions-from-employee-pay/deductions-for-priority-order)) |
| Direct earnings attachment (DEA) | DWP Debt Management | Benefit overpayments | 60% of net earnings ([[12]](https://www.gov.uk/government/publications/direct-earnings-attachment-an-employers-guide/direct-earnings-attachment-a-guide-for-employers)) |
Keeping these apart matters because the calculation method, the protected earnings basis and the body to pay all differ. Treating a DEO like a court AEO, or vice versa, produces the wrong deduction and exposes the employer to penalties.
How to calculate the deduction
The mechanics of a DEO deduction are precise. The order states the amount of child maintenance to collect, and the employer's job is to take that amount from net earnings while respecting the protected earnings floor ([13]). The sequence is fixed and should be followed the same way every payday.
First, the employer checks what counts as earnings for the pay period. Second, it calculates 60% of the employee's net earnings, which becomes the protected earnings figure. Third, it makes the deduction from net earnings, provided doing so still leaves the employee with the protected earnings. Fourth, it may take an extra £1 towards administrative costs. Fifth, it sends the deduction to the Child Maintenance Service ([14]).
The 60% protected earnings rule
Protected earnings is the heart of the calculation. The employer must ensure the deduction leaves the employee with at least 60% of their net earnings, and net earnings for this purpose means pay after Income Tax, Class 1 National Insurance and pension or superannuation contributions ([15]). In practice the employer works out net pay, multiplies it by 0.6 to get the protected floor, and confirms that the maintenance deduction does not push take-home below that line ([16]).
The official worked example is straightforward. If the maintenance owed is £150 a month and the employee's net earnings are £1,200 a month, the protected earnings are £720. Net earnings of £1,200 minus protected earnings of £720 leaves £480 of headroom, comfortably more than the £150 due, so the employer deducts the full £150 ([17]).
The £1 administrative charge sits slightly outside the protected earnings rule. An employer can still take the £1 even if doing so dips the employee below the protected earnings rate, but it must never take the employee below the National Minimum Wage ([18]). The minimum wage acts as the outer boundary that no payroll deduction may breach ([19]).
When the pay packet is too small
Some paydays will not cover the full maintenance amount without breaking the protected earnings floor. When that happens, the employer deducts as much as it can, records the shortfall, and carries the unpaid difference forward to the next payday ([20]). It must also send an updated payment schedule to the Child Maintenance Service so the account reflects what was actually collected.
The official example illustrates the carry-forward. If maintenance owed is £250 a month, net earnings are £500 and protected earnings are £300, the headroom is only £200. The employer sends £200, records the £50 shortfall, and adds that £50 to the next payday's deduction, still respecting protected earnings each time ([21]). Modern UK payroll software tracks these rolling balances automatically, which removes a common source of manual error for small teams running payroll in-house.
What counts as earnings
A DEO can only be applied to net earnings, so defining earnings correctly is essential. The categories that count include wages, fees, bonuses, commission and overtime, along with private or occupational pensions, compensation payments, Statutory Sick Pay, and contractual sick, maternity, paternity, adoption and redundancy pay ([22]). The dividing line is that contractual payments count, while their statutory equivalents in several categories do not.
Several payment types are explicitly excluded. An employer cannot deduct from Statutory Maternity Pay, Statutory Paternity Pay, Statutory Adoption Pay or Statutory Redundancy Pay, nor from social security pensions, allowances or benefits, disability pensions, or guaranteed minimum pension ([23]). If one of these excluded payments is the employee's only income for a period, the employer makes no deduction and updates the payment schedule instead.
The table below summarises the divide.
| Counts as earnings | Does not count as earnings |
|---|---|
| Wages, fees, bonus, commission, overtime | Statutory Maternity, Paternity, Adoption Pay |
| Occupational and private pensions | Statutory Redundancy Pay |
| Statutory Sick Pay, contractual sick pay | Social security pensions, allowances, benefits |
| Contractual maternity, paternity, adoption, redundancy pay | Disability pensions and allowances |
Getting this classification right protects both parties. Deducting from an excluded payment such as Statutory Maternity Pay is an error the employer must reverse, and the correct treatment of statutory versus contractual pay is a recurring theme across payslip deductions generally.
Paying the Child Maintenance Service
Collecting the money is only half the duty. The employer must forward each deduction to the Child Maintenance Service so that it arrives no later than the 19th day of the month following the month in which the deduction was made ([24]). Late or missing payments are the most common trigger for enforcement action against employers.
The legal obligations are set out plainly. By law the employer must supply information to the Child Maintenance Service when asked, send payments promptly to meet the 19th-of-the-month deadline, report any problems with taking payments immediately, and make regular deductions ([25]). An employer that fails to send payments and does not explain why can be taken to court.
Administrative costs and record keeping
The single concession to the employer is the £1 administrative charge that can be kept from the employee for each deduction ([26]). It is modest, but it is a recognised entitlement rather than a favour, and it applies per deduction. Over a year of monthly deductions it is a small offset against the payroll effort involved.
Record keeping underpins compliance. The employer should retain a record of each deduction, the running total of any carried-forward shortfall, and the updated payment schedules sent to the Child Maintenance Service. Accountants and payroll bureaux managing DEOs across many client payrolls typically rely on software that logs each order, applies the protected earnings test automatically, and produces an audit trail per employee.
When more than one order applies
An employee can be subject to more than one earnings order at the same time, and the rules on which order takes priority decide how the employer applies them. In England, Wales and Northern Ireland, a DEO takes priority over other deductions unless the employer has received a priority attachment of earnings order for the same employee ([27]). In Scotland, a DEO takes priority over other deductions in all cases.
The distinction between priority and non-priority orders also affects how shortfalls are handled. Under a priority order, any shortfall in the normal deduction or the protected earnings is carried forward from one payday to the next; under a non-priority order, such shortfalls are not carried forward ([28]). When multiple orders stack on one employee, the employer applies them in priority sequence while ensuring the combined deductions never breach the relevant protected earnings floor. This is one of the more error-prone corners of payroll, and it is precisely the kind of rule that a compliance-focused payroll engine is built to enforce consistently rather than leaving to manual judgement.
Conclusion
A deduction from earnings order turns the employer into a collection agent with real legal exposure. The 60% protected earnings floor, the strict definition of net earnings, the 19th-of-the-month payment deadline and the fines for non-compliance combine into a process that rewards precision and punishes guesswork. None of the individual rules is complex, but applying them correctly every payday, across every affected employee, and alongside any competing orders, is where the effort lies.
The wider pattern is that earnings orders (DEO, AEO and DEA) share a family resemblance but differ in the detail that matters most: who issues them, what they recover, and how protected earnings are set. An employer that understands those differences, keeps clean records and forwards payments on time will stay on the right side of the rules, whatever combination of orders lands on its payroll.
Frequently asked questions
What is the difference between a deduction from earnings order and an attachment of earnings order?
A deduction from earnings order (DEO) is issued by the Child Maintenance Service to collect child maintenance, and it protects 60% of the employee's net earnings ([29]). An attachment of earnings order (AEO) is issued by a court to recover debts such as fines or county court judgments, and its protected earnings rate is stated in the order itself rather than fixed at 60% ([30]). They are separate instruments with separate rules.
How much of an employee's wages can a deduction from earnings order take?
There is no fixed maximum percentage for the maintenance itself, but the deduction must always leave the employee with at least 60% of their net earnings, known as protected earnings ([31]). If the full amount owed would breach that floor, the employer deducts only up to the floor and carries the shortfall forward to the next payday.
Can an employer refuse to operate a deduction from earnings order?
No. Operating a DEO is a legal obligation once the order is received, and an employer can be fined up to £500 for each missed payment and up to £1,000 for failing to provide information requested by the Child Maintenance Service ([32]). Any dispute about the underlying maintenance is between the paying parent and the Child Maintenance Service.
When does the employer have to pay the deducted money to the Child Maintenance Service?
The employer must send each deduction so that it reaches the Child Maintenance Service no later than the 19th day of the month following the month in which the deduction was made ([33]). The employer may keep an extra £1 per deduction towards its own administrative costs.
