Payroll is not choosing to take the money and cannot choose to stop. Section 47(1) of the Debtors (Scotland) Act 1987 puts the duty on the employer and leaves no discretion in it.

Here is what the deduction does to your pay, what to ask, and what each answer establishes. How you know if you have a wage arrestment covers working out whether you have one in the first place.

Your employer deducts a sum calculated under the Act from your net earnings on every pay day and pays it to the creditor as soon as is reasonably practicable. The money is taken before your pay reaches you.

It is worked out afresh every period

The table is applied again each time you are paid. So the deduction rises when your net earnings rise and falls when they fall.

That is why two months on the same salary can produce two different figures. Why your wage arrestment is taking more than you expected runs through the reasons a period comes out higher.

A period below the threshold produces nothing

Where net earnings for the period fall in the nil band the deduction is nil, and the arrestment carries on regardless. What happens if you earn below the threshold covers what actually brings one to an end.

It stops at the top band, not at half your pay

The highest band takes a fixed amount plus 50% of the excess above it rather than half of everything. Whether an arrestment can take more than half your wages sets out how the top band actually behaves.

Because they are operating a statutory instruction rather than a company policy. An employer who does not operate a valid earnings arrestment becomes liable for the sums that should have been deducted.

What the employer is actually being told to do

Deduct a sum calculated in accordance with the Debtors (Scotland) Act 1987 from net earnings on every pay day, and pay it over. An employer’s legal duties for a wage arrestment sets the duty out in order.

There is no affordability test for payroll to apply and no power to spread it more gently. Asking for a smaller deduction puts the question to the one person in the chain who cannot answer it.

Who at work sees any of it

Only payroll and whoever processes the paperwork need to know. Whether your colleagues find out about your wage arrestment covers who sees what and why.

Ask which instrument the deduction is under, which net earnings figure the table was applied to, and which table was used. Those three answers between them settle almost every question worth asking.

The questions, and what each one gets you

Put it in writing and keep the reply

A short email is enough, and it gives you a dated record of the figures you were given. That record is what makes the figures checkable.

Ask for a balance from the creditor as well as the figures from payroll. Whether sheriff officer fees are added to your wage arrestment balance covers what sits inside the sum being collected.

Start from net earnings for the period, then apply the statutory table for your pay frequency. Net earnings is a defined figure and it is not take-home pay.

The figure the table is applied to

Net earnings is your pay for the period after income tax, National Insurance primary class 1 contributions, pension scheme contributions and a priority child maintenance deduction from earnings order. What counts as net earnings sets out the four items with the paragraph each sits in.

Nothing else comes off before the table is applied. Whether a wage arrestment is taken before or after tax covers the ordering in full.

What the figures look like

Net monthly earnings of £1,800.00 produce £172.50, and £2,200.00 produces £252.50. Net monthly earnings of £749.00 produce nothing at all.

How much they can take from your wages sets out every band above the threshold.

On the weekly table, net earnings of £400.00 produce £36.85 for that week. Those figures come from Schedule 2 as substituted by the Diligence against Earnings (Variation) (Scotland) Regulations 2024, in force since 6 April 2025.

Six checks you can run yourself

There is no fortnightly table. Fortnightly pay is normally handled using the daily table or by applying the weekly table to each week in the period, so ask payroll which method they used.

An employer may deduct £1.00 per deduction as an administration charge. It comes out of your pay on top of the arrested amount rather than out of what the creditor receives.

Where it sits in the order

The charge is taken after the deduction has been calculated, not before. It never forms part of the net earnings figure the table is applied to.

That ordering matters more than the pound does. A charge treated as part of net earnings would pull the whole calculation out by more than a pound.

What it comes to over a year

On monthly pay it is £12.00 across twelve deductions. On weekly pay it is a pound for each week in which a deduction is taken.

The charge attaches to each deduction the employer makes. Ask payroll how a nil period was handled.

Several different instruments can produce a deduction from pay, and they have different rules, different floors and different routes of challenge. Which one it is changes what you can do next.

The ones that exist in Scotland

An earnings arrestment, a conjoined arrestment order, a current maintenance arrestment, a child maintenance deduction from earnings order, a direct earnings attachment, a debtor contribution order and a trust deed payment instruction. The seven types of wage arrestment in Scotland takes each one in turn.

A direct earnings attachment and a child maintenance order both work to a 60% retained earnings rule, and an earnings arrestment does not. The DWP publishes an employer’s guide to direct earnings attachments, and which arrestment takes priority keeps the floors apart.

Two deductions at once

Only one diligence against earnings can operate against the same employment at a time, and a current maintenance arrestment is the exception that can run alongside an ordinary earnings arrestment. Whether you can have more than one at the same time works through the combinations.

Ask payroll in writing for the net earnings figure used and the table applied. If that does not resolve it, section 50(3) of the 1987 Act allows an application to determine a dispute about how the arrestment is operating.

Start with the input, not the band

A difference can come from the figure the table was applied to, or from the frequency used, rather than from the band itself. Challenging a wage arrestment you think is wrong sets out what each application is actually for.

Section 50(1) is the declarator that an arrestment is invalid or has ceased to have effect, and applications go to the sheriff court.

What section 50 will not do

It will not reduce the deduction because you cannot afford it. There is no affordability or hardship ground against an earnings arrestment, and the unduly harsh test reaches funds and moveable property rather than wages.

Where the figure is right but unmanageable, the answer is a statutory route rather than a challenge. How you stop a wage arrestment in Scotland sets those out, and an approved Debt Payment Programme under the Debt Arrangement Scheme stops an existing arrestment and freezes interest, fees and charges.

Council tax arrears are not reported to credit reference agencies, and a decree from an ordinary court action can sit on a credit file for six years from the date of judgment. A bank account is reached by a different diligence with different rules.

Your credit file

Whether a wage arrestment affects your credit score covers the arrestment, and whether council tax arrears show on your credit report separates the Register of Decrees from a credit reference agency record.

Where the debt came from an ordinary court action, a decree on a credit file is held for six years from the date of judgment. The Register of Decrees entry runs for six years unless the decree is set aside or cancelled.

Your bank

An earnings arrestment is served on your employer rather than on your bank, and the money is taken before it reaches your account. A bank arrestment is a separate diligence, attaching only the balance above the £1,000 protected minimum balance fixed on the face of the statute since 1 November 2022.
