If your agency bills a client £12,000 for a project, and you pay a freelancer £8,000 to deliver the work, how does VAT apply? The answer depends on whether you are acting as principal or as agent. Get this wrong, and you could underpay HMRC or leave your client with a VAT bill they cannot reclaim. This is one of the most common areas where creative agencies trip up on VAT for agencies.
Let me walk through the rules, the scenarios, and the practical steps you need to take. I will use real numbers and real agency examples throughout.
The Core Distinction: Principal vs Agent
HMRC draws a clear line between two ways of working with subcontractors.
Principal: You contract directly with the client. You are responsible for delivering the work. You invoice the client for the full project. The freelancer works for you, not the client. This is the standard model for most creative, digital, and marketing agencies.
Agent: You introduce the client to the freelancer. The freelancer contracts directly with the client. You invoice the client for your introduction fee or commission, not for the full project. This is less common in creative agencies but does happen in recruitment and some PR models.
Most agency founders reading this will be operating as principal. You take the brief, you manage the project, you invoice the client. The freelancer is your subcontractor. That means the VAT treatment follows a specific path.
When You Are Principal: The Standard VAT Treatment
Here is the rule in plain English.
You invoice the client for the full project amount. You charge VAT at the standard rate (20%) on the full invoice. You account to HMRC for that VAT on your VAT return.
The freelancer invoices you for their work. They charge you VAT (assuming they are VAT-registered). You reclaim that input VAT on your VAT return, subject to the normal rules.
Your VAT position is the difference between the output VAT you charged the client and the input VAT you paid the freelancer.
Worked Example
Your agency, based in Shoreditch, wins a website build project. Total fee: £24,000 plus VAT. You subcontract the front-end development to a freelancer in Bristol who charges you £8,000 plus VAT.
- You invoice the client: £24,000 + £4,800 VAT = £28,800 total
- Freelancer invoices you: £8,000 + £1,600 VAT = £9,600 total
- Your VAT return shows: output VAT £4,800, input VAT £1,600
- You pay HMRC: £4,800 - £1,600 = £3,200
This is straightforward. The client reclaims the full £4,800 VAT (assuming they are VAT-registered). You reclaim the £1,600. HMRC gets £3,200 net.
The mistake agencies make is thinking they only owe VAT on their margin (the £16,000 difference). That is wrong. You owe VAT on the full £24,000 because you are principal.
The Common Error: Margin Schemes and Agency Work
Some agency founders hear about the Tour Operators Margin Scheme or the VAT margin scheme for second-hand goods and assume a similar principle applies to freelancers. It does not.
There is no general margin scheme for agency subcontracting. You charge VAT on the full invoice value. Period.
The only exception is if you are acting as agent, which we will cover next. But if you are principal, there is no shortcut.
When You Are Agent: The Commission Model
If you genuinely act as agent, the VAT treatment changes. You only charge VAT on your commission or fee, not on the full project value.
This requires a specific contractual structure. The freelancer must contract directly with the client. You invoice the client for your introduction fee or project management fee. The freelancer invoices the client directly for their work.
Worked Example
Same project, but structured as agent. Your fee is £4,000 plus VAT. The freelancer charges the client £8,000 plus VAT directly.
- You invoice the client: £4,000 + £800 VAT = £4,800 total
- Freelancer invoices the client: £8,000 + £1,600 VAT = £9,600 total
- Your VAT return shows: output VAT £800 only
- You pay HMRC: £800
The client reclaims both VAT amounts. You reclaim no input VAT because you did not pay the freelancer directly.
This model is rare in creative agencies. Clients typically want one point of contact and one invoice. But it does happen in some PR and recruitment models. If you use this structure, your contracts and invoices must reflect the agency role clearly. HMRC will look at the substance, not just the label.
Flat Rate VAT and Subcontractors: A Trap for Agencies
If your agency uses the Flat Rate VAT Scheme, the rules around subcontractor costs are particularly important.
Under the Flat Rate Scheme, you charge your clients the full 20% VAT but pay HMRC a lower flat rate percentage (typically between 9.5% and 14.5% for most agency sectors). You keep the difference. However, you cannot reclaim input VAT on most purchases, including freelancer costs, unless you are a limited cost trader.
Here is where it gets tricky. If you are on the Flat Rate Scheme and you subcontract a significant portion of a project, you may be paying VAT on the full invoice to HMRC but unable to reclaim the VAT on the freelancer invoice. That can wipe out your margin.
Worked Example
Your agency uses the Flat Rate Scheme at 12.5% (digital agency sector). You invoice a client £24,000 plus VAT.
- You charge client: £24,000 + £4,800 VAT
- You pay HMRC: 12.5% of £28,800 = £3,600
- You keep: £4,800 - £3,600 = £1,200
But the freelancer charges you £8,000 plus £1,600 VAT. Under Flat Rate, you cannot reclaim that £1,600. Your net position is £1,200 retained minus £1,600 irrecoverable VAT = £400 loss on the VAT alone.
If you subcontract heavily, the Flat Rate Scheme can cost you money. Many agencies switch to standard VAT accounting once their freelancer costs exceed a certain threshold. Our team at Agency Founder Finance has seen multiple clients make this switch after a single large project with heavy subcontracting.
Limited Cost Trader: What It Means for Agencies
Since 2017, the Flat Rate Scheme includes a limited cost trader rule. If your VAT-inclusive spend on relevant goods is less than 2% of your VAT-inclusive turnover (or less than £250 per year if the 2% figure is higher), you are a limited cost trader. Your flat rate percentage jumps to 16.5%.
Most agencies are limited cost traders because their main costs are salaries, rent, and software, not physical goods. Freelancer costs are services, not goods. So freelancer invoices do not count toward the 2% goods threshold.
If you are on the Flat Rate Scheme and subcontract freelancers, check your limited cost trader status. You may already be on 16.5% without realising it. That makes the Flat Rate Scheme even less attractive for agencies with high freelancer costs.
Reverse Charge for Construction: Does It Apply to Agencies?
There is a specific reverse charge for construction services introduced in March 2021. If your agency subcontracts work that falls under the Construction Industry Scheme (CIS), the reverse charge may apply. This is relevant for agencies that build websites, install hardware, or do physical fit-outs for clients.
Under the reverse charge, the client accounts for the VAT on the subcontractor's invoice, not the subcontractor. This removes the risk of missing trader fraud. If this applies to your agency, your freelancer invoices will show "reverse charge" and no VAT. You do not reclaim input VAT. The client accounts for it on their return.
Most creative agencies will not fall under this rule. But if your agency does physical installation work alongside creative services, check with your accountant before your next project.
International Freelancers: VAT on Cross-Border Subcontracting
If you subcontract to a freelancer based outside the UK, the VAT rules change again.
If the freelancer is based in the EU, you may need to apply the reverse charge mechanism. You do not pay VAT on the freelancer's invoice. Instead, you account for VAT on your return as both output and input, netting to zero. This is called the "reverse charge" for services.
If the freelancer is based outside the EU, the rules are different again. Generally, you do not pay VAT on their invoice, and you do not reclaim any. But the specific treatment depends on where the services are used and enjoyed.
This is complex territory. If you regularly use overseas freelancers, speak to your accountant before your next project. One wrong invoice can create a compliance headache that takes weeks to untangle.
Partial Exemption: When Your Client Is Outside the UK
If you invoice a client outside the UK, the VAT treatment of your freelancer costs can get complicated.
Generally, services to overseas business clients are outside the scope of UK VAT. You do not charge VAT on the invoice. But you can still reclaim VAT on your freelancer costs, provided those costs relate to the taxable supplies you make.
However, if your agency makes both taxable and exempt supplies (rare for most agencies, but possible if you offer financial services or insurance-related work), you fall into partial exemption. You can only reclaim VAT on costs that relate to your taxable supplies. This requires a partial exemption calculation at each VAT return period.
Most agencies will never hit this issue. But if your client base includes banks, insurers, or other financial institutions, check your partial exemption position before the next quarter.
Practical Steps: What to Do Now
Here is what I recommend every agency founder does today.
First, check your contracts. Are you acting as principal or agent? If your contracts say you are principal, your VAT treatment should follow the principal model. If you want to use the agent model, rewrite your contracts and invoicing processes first.
Second, review your VAT scheme. If you are on the Flat Rate Scheme and subcontract more than 20% of your project value, run the numbers. Standard VAT accounting may save you money, especially if your freelancers are VAT-registered.
Third, check your freelancers' VAT status. Before you engage a freelancer, confirm whether they are VAT-registered. If they are not, you cannot reclaim VAT on their invoice. That changes your pricing and margin calculations.
Fourth, get your software right. If you use Xero or QuickBooks, make sure your freelancer invoices are coded correctly. Input VAT on subcontractor costs should go to the correct VAT box (box 4 on the standard VAT return). Do not mix them up with other costs.
Fifth, if your contractor mix has changed in the last 12 months, ask your accountant before year-end. A shift from employees to freelancers, or from UK to overseas freelancers, can change your VAT position significantly.
What HMRC Looks For
HMRC has a specific interest in agency VAT treatment. They look for two things.
First, they check whether you are treating subcontractor costs as your own costs when they should be treated as disbursements. A disbursement is a cost you pay on behalf of the client and recharge at cost. If you treat a freelancer invoice as a disbursement, you do not charge VAT on it. But if you are principal, that is wrong. You must charge VAT on the full invoice.
Second, they check whether you are using the Flat Rate Scheme to avoid VAT on high freelancer costs. If your freelancer costs are significant, HMRC may challenge your use of the scheme.
If HMRC opens a VAT inspection, they will ask for sample invoices from both your clients and your freelancers. They will trace the VAT through the chain. Any mismatch between your treatment and the freelancer's treatment will be flagged.
When to Get Professional Help
If you are doing any of the following, speak to your accountant before your next VAT return:
- Subcontracting more than 40% of your project value
- Using overseas freelancers
- Operating on the Flat Rate Scheme with significant freelancer costs
- Considering a switch from principal to agent model
- Invoicing clients in the EU or outside the UK
Our team at Agency Founder Finance works exclusively with agency founders. We see these issues every week. The cost of getting it wrong is far higher than the cost of a quick check before you submit.
If you are unsure about your VAT treatment on a specific project, email your accountant with the contract and the freelancer invoice. A ten-minute review can save you thousands in penalties and interest.
