Tax-efficient ways to buy a van as a sole trader in the UK

Buying a van for your trade business: the tax angle

A van is probably your biggest business expense after materials. How you buy it affects your tax bill for years. Get this right and you could save thousands. Get it wrong and you pay more tax than you need to.

This guide covers the main options for sole traders buying a van in the 2025/26 and 2026/27 tax years, including capital allowances, the Annual Investment Allowance, and the differences between buying, leasing, and hire purchase.

Capital allowances: the basics

When you buy a van for your business, you do not deduct the full cost from your profits in the year you buy it. Instead, you claim capital allowances, which spread the tax relief over time. The main types relevant to vans are:

• Annual Investment Allowance (AIA) — 100% of the cost in year one, up to £1 million per year
• Writing Down Allowance (WDA) — 18% per year on a reducing balance (main pool)
• First Year Allowance (FYA) — 100% for electric vans (zero emission)

Annual Investment Allowance on vans

The AIA lets you deduct the full purchase price of a van from your taxable profits in the year you buy it. The current limit is £1 million, which comfortably covers any van a sole trader is likely to buy.

Example: you buy a Ford Transit Custom for £30,000 (ex-VAT). You can claim the full £30,000 against your profits in the tax year you buy it. If you are a basic rate taxpayer, that saves you £6,000 in income tax (20% of £30,000). If you earn enough to pay higher rate tax, the saving is £12,000 (40%).

The AIA applies to the purchase price, not the list price. Second-hand vans qualify too, provided you buy them for your business.

Electric vans: extra incentives

Zero-emission vans qualify for 100% First Year Allowance regardless of the AIA. They also attract zero benefit-in-kind tax if used through a limited company. For sole traders, the main benefit is the lower running cost (electricity vs diesel) and the full first-year write-off.

The government's plug-in van grant has ended, but electric vans still save money long-term. Charging at home costs roughly 7p per mile compared to 20p per mile for diesel at current prices. Over 15,000 miles per year, that is around £1,950 saved annually on fuel alone.

Buying outright vs hire purchase vs lease

Buying outright

Simplest option. You own the van immediately. Claim AIA on the full price. No ongoing finance costs. The downside is the upfront cash outlay, which can strain cashflow for a new business.

Hire purchase (HP)

You pay a deposit and monthly instalments. You own the van once you make the final payment. For tax purposes, you can claim AIA on the full cash price (not including interest) in the year you take delivery, even though you have not paid it all yet. Interest payments are a separate allowable expense. HP is often the best balance of tax efficiency and cashflow.

Lease (contract hire)

You never own the van. Monthly payments are an allowable business expense, deducted from your profits each month. You cannot claim AIA because you do not own the asset. Leasing works well if you change vans frequently or want to keep your balance sheet clean, but the total cost over the term is typically higher than buying.

VAT on vans

If you are VAT registered, you can reclaim the VAT on a van used wholly for business. Unlike cars, there is no restriction on reclaiming VAT on a commercial vehicle. A £30,000 van has £5,000 of VAT (at 20%). Reclaiming this significantly reduces the effective purchase price.

If you use the van partly for personal use (most tradespeople do), HMRC expects you to only reclaim the business proportion. In practice, if personal use is minimal (commuting to jobs and occasional weekend use), most sole traders reclaim the full amount and HMRC rarely challenges it for genuine commercial vehicles.

Simplified expenses alternative

If you use the simplified expenses method, you claim a flat rate per business mile instead of the actual costs. The rates are 45p per mile for the first 10,000 miles and 25p per mile after that. This covers fuel, insurance, servicing, and depreciation in one flat rate.

Simplified expenses are easier to administer but usually give a smaller deduction than claiming the actual costs plus AIA. Run both calculations for your first year to see which works out better. Use the mileage calculator to compare.

Timing your purchase

Buy your van near the start of your accounting year if possible. This gives you the maximum AIA benefit in the current tax year. If you buy in the last month of your accounting year, you get the same AIA but your cash is tied up for nearly a year before you see the tax benefit.

FAQs

Can I claim for a van I already own?

If you start using a personal van for business, you can claim capital allowances on its market value at the date you start using it for business. Get a written valuation (even a screenshot from AutoTrader for similar vehicles) to support your claim.

What if I use the van for personal trips too?

HMRC allows sole traders to claim capital allowances on a van used partly for personal purposes, but you must reduce the claim by the private use proportion. If 10% of your mileage is personal, reduce your AIA claim by 10%.

Should I buy through a limited company instead?

If you have a limited company, the company buys the van and claims capital allowances through corporation tax. There is usually no benefit-in-kind charge for a commercial vehicle (unlike a car). This can be more tax-efficient for higher earners but comes with additional administrative requirements.
