Sooner or later, most employers receive an official letter telling them to start deducting money from an employee’s wages and send it to a third party. These are attachment of earnings orders and their cousins, and once you receive one you are legally obliged to act. Ignore it, get the maths wrong, or apply the orders in the wrong sequence, and the liability lands on you, not the employee.
There are several different order types, each with its own rules, and they often arrive without much explanation. This guide sets out what each one is, how to handle more than one at a time, and where employers most often slip up.
What an attachment of earnings order is
An attachment of earnings order is an instruction from a court or other authority that requires you, as the employer, to deduct a set amount from an employee’s net pay and pass it to the body that issued the order. The employee does not get a choice, and neither do you. The deduction comes out of pay after tax, National Insurance and pension contributions have been taken off.
The main types you will see
Five types cover almost everything an employer in England and Wales will encounter:
Attachment of Earnings Order (AEO): issued by a civil court for unpaid fines, maintenance, or county court judgment debts. These split into priority orders (fines and maintenance) and non-priority orders (judgment debts).
Council Tax Attachment of Earnings Order (CTAEO): issued by a local authority after a liability order for council tax arrears, with deductions set by statutory percentage tables.
Deduction from Earnings Order (DEO): issued by the Child Maintenance Service for child maintenance.
Direct Earnings Attachment (DEA): issued by the Department for Work and Pensions to recover benefit overpayments. A DEA does not need a court order behind it.
Scottish equivalents: in Scotland these are handled through diligence against earnings, mainly the earnings arrestment and the current maintenance arrestment.
Priority rules when there is more than one order
Employees can have several orders running at once, and this is where most errors happen. Priority orders are always dealt with before non-priority ones. Among the priority orders, you apply them in the order you received them, with each later order calculated on the pay that is left after the earlier one has been taken.
A DEA generally ranks behind genuine priority orders such as a Child Maintenance Service DEO or a court order for fines, then sits ahead of non-priority orders. Student loan repayments, although not technically an order, are treated like a priority deduction. There is also a practical difference in how shortfalls are handled: with a priority AEO, any amount you cannot deduct this payday is carried forward to the next one, whereas with a non-priority AEO it is not, and you simply resume the normal deduction next time.
Working out which order takes precedence, on the right earnings, in the right sequence, is fiddly and easy to get wrong. A payroll bureau that manages court orders correctly removes that risk entirely, because the priority logic is applied for you every pay run.
Protected earnings
No order can leave an employee with nothing. Most carry a protected earnings rule, an amount of net pay that must remain after deductions. For a Direct Earnings Attachment and a child maintenance DEO, the protected figure is 60% of net earnings, so total deductions cannot exceed 40% of net pay. If a deduction would breach that floor, you reduce it, and for a DEO you carry the shortfall forward.
Court AEOs work slightly differently. The protected earnings rate is written into the order itself by the court rather than fixed by a percentage. A CTAEO has its protection built into the deduction tables, with nil bands at the lower end of earnings.
The deduction tables
A Direct Earnings Attachment uses fixed percentage bands applied to net earnings. The standard rate runs as follows for monthly paid employees:
Net monthly earnings
Standard deduction
Up to £430
Nil
£430.01 to £690
3%
£690.01 to £950
5%
£950.01 to £1,160
7%
£1,160.01 to £1,615
11%
£1,615.01 to £2,240
15%
£2,240.01 and above
20%
A higher rate table exists too, rising to 40% on the top band, and the DWP tells you which rate to apply. Council tax orders use their own statutory tables, while court AEOs and child maintenance DEOs state the exact amount to deduct rather than a percentage.
The £1 administration fee
You are entitled to keep £1 from the employee’s pay for each deduction you make, towards your administrative costs. This applies to a DEA, a child maintenance DEO, a court AEO and a CTAEO. You can take the £1 even if it dips the employee below their protected earnings, but never below the National Minimum Wage, and you cannot charge it in a period where no deduction is made at all.
What to do when the employee leaves
When an employee with an order leaves, you must tell the issuing body promptly. For a court AEO, write to the Centralised Attachment of Earnings Payments office within 10 days. For a DEA, notify DWP Debt Management. For a CTAEO, tell the local authority, usually within 14 days. For a child maintenance DEO, tell the Child Maintenance Service. Our guide to processing starters and leavers without penalties covers the wider leaver process this fits into.
Penalties for getting it wrong
These obligations have teeth. Failing to operate a DEA correctly can mean a fine of up to £1,000. With a child maintenance DEO, you can be fined £500 for each missed payment and up to £1,000 for not providing requested information. Both employer and employee can be fined for a court AEO where deductions are not made or false information is given about earnings.
Court orders are exactly the kind of complex, unforgiving deduction that is safer handled by a payroll specialist than squeezed in around everything else. If you would rather not decode a statutory table every pay run, our payroll service operates these deductions as part of the wider process.
