Do IR35 Rules Apply to HGV Drivers in the UK?

IR35 rules can apply to HGV drivers, and the sharpest dividing line HMRC draws is whether you supply the vehicle or only your labour. HMRC’s Employment Status Manual states that drivers who provide only labour, using vehicles owned, maintained, and insured by the hiring company, are “likely to be employees,” while drivers who also provide the means of transport are “likely to be self-employed” even if they work mainly for one client.¹ That single distinction pushes most agency drivers on client fleets toward inside IR35, and most owner-drivers running through their own limited companies toward outside. Everything else in the assessment fine-tunes that starting point.

Why the Vehicle Matters So Much

HMRC keeps a dedicated section in its manual for commercial vehicle drivers, and the message is direct: if you turn up, drive someone else’s truck, and go home, the arrangement looks like employment regardless of what the paperwork says. In haulage, the vehicle is the key asset, and who owns it carries significant weight in the assessment.¹

If you own or lease your own HGV through a limited company (often called a personal service company, or PSC), you already meet the most important indicator HMRC looks at. You pay for the vehicle, the insurance, the fuel, the maintenance, and you carry the loss if the truck breaks down mid-job. That pattern of investment and risk is what HMRC expects from a genuine contractor. Owning the vehicle alone does not seal an outside-IR35 result, though. HMRC still runs the wider working relationship through the standard employment status tests.

The Tests That Decide Borderline Cases

Three tests do most of the work: control, personal service (substitution), and mutuality of obligation. HMRC and the tribunals weigh the overall picture rather than any single factor, so a weak score on one test can be offset by strong indicators elsewhere.

Control

Control asks whether the client dictates what you do, when, where, and how. For HGV work this is the awkward test, because delivery slots, loading windows, and routes are often set by logistics reality rather than driver choice. That level of direction can resemble employment.

Owner-drivers usually score best on the “how.” If you set your own driving methods, rest breaks, refuelling strategy, and maintenance schedule without supervision, that points to self-employment. Drivers who plug into a client’s fleet management system, sit through team briefings, and follow the client’s standard operating procedures sit in a weaker position.

Substitution

An employee has to do the work personally; a genuine contractor can send someone else. HMRC’s guidance says an unqualified right to provide a substitute is a strong pointer toward self-employment and could even be decisive on its own.²

The right has to be real. HMRC looks at whether substitution has actually happened or realistically could. A contract clause saying you can send another qualified HGV driver is only worth something if the client would accept the replacement. If they would refuse anyone you propose, or if pre-approval amounts to a veto, HMRC may treat the clause as a sham. Never having needed to send a substitute does not, on its own, mean the right is not genuine.²

Mutuality of Obligation

Mutuality asks whether the client must offer work and you must accept it. During any engagement where you are actually working and being paid, HMRC treats a basic level of mutual obligation as automatic. The Supreme Court confirmed this in the PGMOL decision, describing it as a “wage-work bargain” that is a precondition to any employment relationship.³

What matters more is what happens between engagements. If the client is not obliged to offer you the next job and you are free to refuse work, the case for employment weakens. Drivers picking up loads from different clients on an ad hoc basis are on stronger ground than someone with a standing arrangement to show up at the same depot every Monday morning.

Financial Risk

Employees are insulated from financial loss. Contractors absorb it. For HGV drivers, that shows up in several ways:

Vehicle breakdowns you have to pay to fix, with lost income while the truck is off the road.
Fixed-price work per delivery, where delays and detours eat into your margin.
Your own goods-in-transit, public liability, and commercial vehicle insurance.
Redoing a botched delivery at your own expense.

A driver on a straight daily rate with no vehicle costs, no insurance premiums, and no liability for problems carries little more risk than an employee collecting a wage. The more of that exposure sits with you, the stronger the outside-IR35 case.

Being Part and Parcel of the Client’s Business

If you wear the client’s uniform, use their email address, sit in their staff meetings, or appear on their org chart, you look integrated rather than independent. Drivers dispatched from the client’s depot, running the client’s livery, and reporting to their transport manager in the same way employed drivers do will struggle here.

Who Actually Makes the Determination

It depends on the client. For public sector clients, and for medium and large private sector companies, the client assesses your employment status and issues a Status Determination Statement (SDS). The SDS has to state whether the engagement is inside or outside IR35 and give the reasoning.⁴ The framework has applied to the public sector since April 2017 and to medium and large private sector clients since April 2021.⁵

The client also has to take “reasonable care” over the decision. A determination that fails those tests is invalid, and the tax and National Insurance responsibility shifts to the client itself.⁴ Many large haulage and logistics firms issue blanket inside-IR35 determinations to protect themselves, which pushes genuine owner-drivers into the wrong box.

If your client is a small private sector company, the responsibility stays with your own limited company. A company counts as small under the Companies Act 2006 if it meets at least two of: annual turnover no more than £15 million, balance sheet total no more than £7.5 million, and no more than 50 employees on average. Plenty of smaller haulage operators sit inside that threshold, so the assessment is yours to make.

Challenging an Inside-IR35 Determination

If the client puts you inside IR35 and you disagree, you can challenge it. The disagreement can be raised at any point before the final payment under the contract, and there is no cap on how many times you can dispute the decision during the engagement.⁶

Give reasons tied to the status indicators. A challenge without reasons can be rejected outright. Once you submit, the client has 45 calendar days to respond. If they simply repeat their previous conclusion, you can raise the disagreement again with new facts. Without new information, the client is entitled to stand by the original determination and close the matter.⁶ A specific, well-reasoned disagreement referencing your substitution right, lack of control, and financial risk carries far more weight than a general objection. If the tax difference over the contract is meaningful, paid advice before submitting usually pays for itself.

What Happens When You Are Inside IR35

If the engagement is inside IR35, the deemed employer in the supply chain has to deduct Income Tax and employee National Insurance from payments to your limited company, pay employer National Insurance and any Apprenticeship Levy on top, and report it all through Real Time Information. The deemed employer is usually whoever sits directly above your PSC in the contractual chain, often a recruitment agency.⁷

One warning worth stating plainly, because it catches drivers out: being inside IR35 does not give you employment rights. It applies for tax only. You do not gain holiday pay, sick pay, employer pension contributions, or unfair dismissal protection. Your employment law status is unchanged. The tests overlap with the ones tribunals use for employment rights, but a finding under one does not carry across. Inside IR35 means the tax of an employee with the rights of a contractor, which is why drivers who spend most of their time inside IR35 should genuinely weigh up whether a permanent role would be better.

What Outside IR35 Is Worth

Outside IR35, you keep the full tax efficiencies of the limited company: a low salary combined with dividends, and legitimate business expenses set against company profits. For owner-drivers the deductible costs can be substantial, including fuel, maintenance, tyres, MOT, road tax, goods-in-transit and public liability insurance, LGV licence renewals, Driver CPC training, digital tachograph card fees, medical exams, subsistence on multi-day runs, accountancy fees, and business use of phone and home office.

Every expense has to be incurred wholly and exclusively for the trade. Inside IR35, none of those deductions reduces your deemed employment payment, apart from a flat 5% allowance (available only where your own PSC is responsible for the assessment) and expenses that would also be deductible for an employee. The gap in take-home pay between inside and outside can run into thousands of pounds a year on a full-time engagement.

Practical Steps to Strengthen an Outside-IR35 Position

Own or lease your vehicle. HMRC’s guidance treats supplying the means of transport as the single biggest indicator of self-employment for commercial vehicle drivers.¹
Put a real substitution clause in the contract. Make sure the right is exercisable in practice, and use it at least once if you can.
Work for more than one client. Multiple income sources look like a business, not a job.
Carry genuine financial risk. Take fixed-price work where possible, pay for your own insurance and maintenance, and absorb the cost of mistakes.
Stay out of the client’s internal furniture. Skip the uniform, the internal email, the org chart.
Keep records. Invoices, contracts, evidence of substitution, correspondence showing you set your own working methods. Paperwork wins HMRC arguments.

Drivers who only supply their labour and drive the client’s fleet face a much steeper climb. HMRC’s guidance essentially presumes employment in that scenario, and the other indicators would have to point strongly the other way to overcome it. For most agency drivers using the haulage firm’s own trucks, an inside-IR35 determination is likely to be the correct one.
