Below is the arithmetic on a range of balances, the point where the 10% lands, and what else can be added after it.

It is 10% of the council tax still outstanding when the warrant is granted, not 10% of your annual bill. Anything already paid for the year has come off the figure before the tenth is worked out.

The arithmetic on a range of balances

The table runs a set of illustrative balances through the calculation. They are worked examples rather than figures taken from any real account.

Why a part-paid year gives a smaller figure

Say the annual bill is £1,400.00 across 10 instalments and 7 have been paid. The £420.00 left is what carries the surcharge, so £42.00 is added and the balance becomes £462.00, and our council tax billing guide explains how the annual charge and its instalments are put together.

A tenth of the whole annual bill would have been £140.00. That is not the figure that applies.

Why the figure on your letter may still look different

Water and sewerage charges are billed alongside council tax and handled separately, which makes a total look odd at a glance. Ask the council which part of the figure is council tax.

On grant of the summary warrant, which is the step straight after the final notice period runs out. It is worked out on the council tax still outstanding at that point rather than on your annual bill.

How the warrant is granted

The council applies to the sheriff court supported by a certificate, and the warrant is granted with no hearing. You are not summoned, you do not attend, and liability cannot be contested at that point.

The procedure sits in the Council Tax (Administration and Enforcement) (Scotland) Regulations 1992, particularly regulation 30, alongside s.106 of the Local Government (Scotland) Act 1975. The power itself is Schedule 8 paragraph 2 of the Local Government Finance Act 1992.

That schedule sets no time limit, no duration and no expiry. Our guide to what happens if you do not pay your council tax in Scotland covers the stages that lead there.

The stages before it, and where the 10% is still avoidable

Each stage is triggered by the one before rather than by a calendar date. Day counts vary by council policy, so treat them as typical rather than guaranteed.

No. It is a statutory surcharge added on grant of the warrant, and sheriff officer fees are a separate charge, set by an Act of Sederunt and added to what you owe.

Where the confusion comes from

The 10% is sometimes mistaken for a sheriff officer charge. It lands when the court grants the warrant, which can be before any firm has been instructed.

The council applied for the warrant, so the council is who to ask about the figure.

What sheriff officers do add

The council instructs a sheriff officer firm, and the firms working for Scottish councils include Scott & Co, Stirling Park, Walker Love and Alex M Adamson.

They are officers of the court, appointed by and accountable to the sheriff, and they are not bailiffs. Their fees are set by the court under an Act of Sederunt and added to the debt, rather than set by the firm.

The fee scale is updated from time to time, so ask for a breakdown of any expenses charged to your account.

Everything that can be added to a council tax balance

Each addition has a different source and a different moment at which it lands.

The 10% is added by statute when the sheriff court grants the warrant, so plan around it as part of the balance. Where the liability underneath was wrong, correcting that liability changes the figure the 10% was applied to.

Where the figure comes from

The surcharge is a statutory addition made on grant of the warrant rather than a discretionary charge somebody chose to apply to you. Treat anyone promising to get it wiped with caution.

That is not the same as saying the number is beyond question, because a surcharge calculated on a wrong balance is wrong with it.

Where the liability itself may be wrong

Start with whether you were the person liable for the whole period charged. Our council tax liability guide sets out the hierarchy running from resident owner to non-resident owner.

Single person discount is 25%, and there are further discounts and disregards for students, apprentices, care leavers under 26 and live-in carers. A disabled band reduction charges the bill one band lower where a disabled resident needs an extra room or wheelchair space indoors.

Council Tax Reduction can cover up to 100% of your liability, and working-age awards can be backdated up to six months where there was continuous good cause for applying late.

Who to talk to instead

A free money adviser will not make the surcharge disappear either, and they can check the balance, the discounts and whether a statutory route fits. Our council tax debt advice page covers what to ask a recovery team for.

Each summary warrant carries its own 10%, added to the council tax outstanding when that warrant is granted. Ask the council how each surcharge on your account was worked out.

Ask for the arrears split by financial year with the surcharge shown against each. That gives you a total you can check line by line.

Which year your payments clear

Payments are normally allocated to the oldest year of arrears first unless you say otherwise, which matters when you are trying to keep the current year out of recovery. Our guide to setting up a council tax payment arrangement covers how to put both years into one figure.

If you want a payment credited to a particular year, put that in writing at the time.

Yes. The same 10% statutory surcharge applies to unpaid non-domestic rates, which is the business equivalent of council tax.

The route is the same in structure

A summary warrant is granted without a hearing, the surcharge is added to the rates outstanding, and sheriff officers can be instructed afterwards. The arithmetic in the table above works identically on a rates balance.

Ordinary attachment applies to goods outside a dwelling, which includes business premises.

What a rates payer should ask for

Ask the council for the balance the surcharge was calculated on, split by the years each warrant covers. It is the quickest way to check a total that looks too big.

A bank arrestment behaves differently for a business, because the protected minimum balance of £1,000 applies to personal accounts rather than business accounts.

The surcharge falls under the same 20-year long negative prescription as the council tax it was added to. Council tax and the surcharges, fees and expenses that go with it sit outside the 5-year rule covering most consumer debt.

Why council tax sits outside the five-year rule

Schedule 1 paragraph 2(fd) of the Prescription and Limitation (Scotland) Act 1973 expressly excludes council tax and non-domestic rates from the short negative prescription in s.6. The exclusion reaches the associated surcharges, fees and enforcement expenses, which is where the 10% sits.

So the five-year period that extinguishes an old credit card balance never touches this, and the 20-year period in s.7 applies instead.

Why twenty years is not a countdown

Executing any form of diligence is a relevant claim under s.9. Since 28 February 2025 a relevant claim extends the 20-year period until it is finally disposed of rather than restarting it.

A payment or a written acknowledgement has no effect on the 20 years, because s.10(1) of the 1973 Act now reaches ss.6 and 8A only. The 5-year rule in s.6 is unchanged.

Section 13A also presumes an obligation extinguished unless the creditor proves otherwise. The 20 years runs from the date the obligation became enforceable, which is a question for advice on your own facts.

Deal with the balance before the council applies for the next thing, whether that is a warrant on another year or sheriff officers on this one. A payment arrangement, a Time to Pay Order and the Debt Arrangement Scheme each do that in a different way.

Talk to the council first

Once the right to instalments has gone, ask the council about a special payment arrangement covering the whole remaining balance including the surcharge. Reinstating instalments is at the council’s discretion rather than a right.

Councils commonly work to the current financial year and will consider longer where affordability is evidenced.

A Time to Pay Order at the sheriff court

A Time to Pay Order is competent against a summary warrant, and where the sheriff grants one the sheriff must recall any existing earnings arrestment. For other diligence the sheriff only may recall.

The balance has to be £25,000 or less excluding interest. A Time to Pay Direction is not available here, because a direction responds to a court action.

It is not settled whether an earnings arrestment alone satisfies the entry conditions, so treat this as a route to check rather than an entitlement. A money adviser or the sheriff clerk at your local sheriff court can confirm whether an application is competent on your facts.

The Debt Arrangement Scheme and a moratorium

Once a Debt Payment Programme under the Debt Arrangement Scheme is approved, an existing earnings arrestment stops and creditors cannot start new diligence. The Accountant in Bankruptcy runs it, with interest, fees and charges frozen and written off on completion.

A statutory moratorium gives six months of protection and you get one per rolling 12 months. It stops service of a charge for payment, stops new diligence and stops creditor petitions for sequestration.

It does not stop a creditor obtaining a decree, and interest and charges keep accruing throughout.

What a wage arrestment would take instead

Because the council holds a warrant, it can move to an earnings arrestment without serving a charge for payment first, which is only required for an ordinary court decree.

Deductions come off net pay under Schedule 2 to the Debtors (Scotland) Act 1987, on tables in force since 6 April 2025. Net monthly pay of £1,800.00 gives £172.50 a month.

Our wage arrestment calculator runs your own figure, and your employer may also take £1.00 per deduction as an administration charge.
