VAT on Agency Ad Spend: Disbursement or Recharge? What UK Businesses Need to Know

If your digital marketing agency manages Google Ads, Meta campaigns or LinkedIn advertising on your behalf, you’ve probably noticed the monthly invoice can get complicated. There’s the management fee, the ad spend itself, and sometimes a line labelled “disbursement” or “recharge.” And whether VAT appears against each of those lines varies.

It’s one of the more genuinely confusing compliance questions for UK small businesses. So let’s clear it up.

The Short Version (For Time-Poor Business Owners)

Whether VAT applies to agency ad spend your agency recharges to you comes down to one question: is your agency acting as your agent or as a principal?

If they are acting as your agent — truly passing costs through on your behalf — the ad spend may qualify as a disbursement, and VAT would not apply to it. If they are acting as a principal — buying the advertising in their own name and reselling it to you — VAT applies to the full amount.

In practice, most UK digital agencies are acting as principals. That means you should expect 20% VAT on ad spend recharges.

Read on for why that matters and what to check with your agency.

What Is a Disbursement, and Why Does It Matter?

HMRC’s guidance on costs and disbursements passed to customers draws a clear line between two types of costs your agency might pass on to you:

Disbursements are costs the agency paid on your behalf, where you were always the intended recipient of the service. No VAT is charged on top because the agency is simply collecting money you already owed to a third party.

Recharges are costs the agency incurred themselves and is passing on as part of their service to you. Standard rate VAT (20%) applies.

The distinction sounds simple. The application is where it gets tricky.

HMRC’s Eight-Condition Test for Digital Agency Ad Spend VAT

To treat a cost as a disbursement (and not charge you VAT on it), HMRC requires all eight of the following conditions to be met:

1. The agency acted as your agent when paying the third party
2. You — the client — used the goods or services, not the agency
3. You were responsible for paying the third party
4. The agency was authorised by you to pay on your behalf
5. You knew the goods or services were being provided by a third party
6. The agency’s outlay is separately itemised on your invoice
7. The amount charged back to you is exactly what the agency paid — no markup
8. The goods or services are clearly additional to the agency’s own services

Miss even one of those conditions and the cost becomes a recharge — and VAT applies.

Where Most Digital Agencies Fall on This

Here is the part that catches a lot of people out.

When your agency signs up for a Google Ads account, a Meta Business Manager account, or a LinkedIn Campaign Manager account, they typically set those up in their own name. The contract is between the agency and the platform. The agency is the customer in HMRC’s eyes.

That means the ad spend flows from the agency to Google or Meta as the agency’s own expenditure. When they then recharge it to you, they are not passing through a cost you already owed — they are selling you a service they delivered. That makes it a recharge, and VAT must be charged at 20%.

This is true even if your agency describes the line on the invoice as a “disbursement” or a “pass-through cost.” What matters to HMRC is the legal and contractual reality, not the label.

If you’ve been wondering why Google Ads costs what it does, the VAT treatment of recharged spend is one piece of the picture — your invoice may be larger than the raw ad budget precisely because VAT applies to the whole recharge.

There Are Situations Where Disbursements Are Possible

If your agency has set up the advertising accounts directly in your name — so the contract with Google or Meta is between you and the platform — and the agency is simply administering spend you are already committed to, the disbursement treatment can apply.

This is more common in media buying arrangements where a specialist agency acts purely as a buyer on your behalf, with full written authorisation, and where the exact amounts are passed through without any markup.

To make it work, you would typically need:

• Accounts held in your business name, not the agency’s
• Clear written authorisation for the agency to pay on your behalf
• Invoices that separately itemise the ad spend, showing the exact third-party cost
• No management fee bundled into the ad spend line

Getting this right requires deliberate structuring from the start. Most day-to-day PPC management relationships are not set up this way.

What Does This Mean for Input VAT Recovery?

If your agency charges VAT on ad spend recharges, the good news is that if you are VAT-registered, you can reclaim that input VAT in the normal way — provided the spend was for your business purposes and you hold a valid VAT invoice.

So for most VAT-registered businesses, the 20% is not a permanent cost. It flows through your VAT return.

For businesses below the VAT threshold (currently £90,000 turnover), or for businesses that are VAT-exempt (certain healthcare, financial services, and education providers), the VAT on recharged ad spend is an actual cost you cannot recover. In those cases, it is worth having a clear conversation with your agency about how they structure the billing. It may also be worth reviewing your overall PPC budgets to account for the VAT element correctly.

Common Mistakes Agencies and Clients Make

Labelling recharges as disbursements without meeting the conditions. This is surprisingly common and creates a VAT under-reporting risk for the agency, plus potential compliance issues for the client.

Not checking whether the ad accounts are in the right name. If you want true disbursement treatment, the account needs to be in your name from day one. Retrofitting this later is complex.

Assuming the arrangement is the same as the old way agency media buying worked. Traditional media agencies sometimes operated under genuine disclosed agency structures. Modern digital platforms tend not to work that way — they prefer direct contracts with whoever holds the account.

Forgetting about reverse charge VAT. When a UK agency buys advertising from Google, Meta or LinkedIn — platforms based outside the UK — the reverse charge mechanism applies. The agency accounts for VAT on that purchase internally (it usually nets to zero on their return). This is separate from what they then charge you, but it does affect how the numbers flow through their books.

The fuller technical treatment of these rules is at paragraph 25.1.1 of HMRC VAT Notice 700 if you want to go deeper.

The Honest Bottom Line

For most UK small businesses working with a digital agency on agency ad spend VAT:

• Management fees: Always subject to VAT at 20%
• Ad spend recharged to you: Almost certainly also subject to VAT at 20%, because the agency is acting as a principal
• True disbursements: Possible, but only with deliberate structuring and full documentation

If you are VAT-registered, this is largely a cash flow point rather than a permanent extra cost. If you are not registered for VAT, it is worth asking your agency to show you exactly what is being charged and why.

Not Sure How Your Agency Is Handling This?

It is worth asking. A simple question — “Are you treating the ad spend as a disbursement or a recharge on your VAT return, and why?” — will tell you a lot about how well your agency understands the compliance picture.
