How to Record Van Expenses Without Tax-Time Panic

A £90 fuel stop, a new tyre and an MOT can all be legitimate business costs. But if they are sitting in the van door pocket or buried in your bank feed, they are no use when Self Assessment comes around. Knowing how to record van expenses properly means less late-night sorting, a clearer view of what the van is costing you, and a better chance of claiming what you are entitled to.

For most sole traders, the key is not complicated bookkeeping. It is choosing one sensible method, recording costs as they happen, and keeping enough detail to show what was business and what was personal.

First, decide how you will claim for the van

You generally have two ways to claim vehicle costs as a sole trader: mileage rates or actual costs. The right one depends on how you use the van and what it costs to run.

Option one: claim business mileage

With the mileage method, you record each business journey and claim a flat rate per mile. For vans, the usual approved mileage allowance is 45p per mile for the first 10,000 business miles in the tax year, then 25p per mile after that.

This is often the cleanest option if you use the van for both work and private trips. You do not need to split every fuel bill, insurance payment or repair between business and personal use. Instead, keep a mileage log showing the date, where you travelled, why you travelled and how many business miles you covered.

The mileage rate is designed to cover the general running costs of the vehicle, including fuel, servicing, repairs, insurance, vehicle tax and depreciation. You can normally claim business parking charges and tolls separately, but not parking fines or speeding fines.

Mileage works well for a plumber travelling between call-outs, an electrician visiting sites, or a decorator picking up materials. It is simple, provided you actually keep the mileage record. A rough guess made ten months later is not a record.

Option two: claim actual van costs

The actual-cost method means recording what you genuinely spend to buy, run and maintain the van. This can include fuel, insurance, servicing, repairs, tyres, MOTs, breakdown cover, vehicle tax, finance interest and lease costs, where they relate to the business.

If you use the van only for work, claiming actual costs can be straightforward. If you also use it for weekend trips, family jobs or other personal travel, you must only claim the business proportion. So if 80% of the van use is for work and 20% is private, you would usually claim 80% of eligible running costs.

This method can produce a larger claim where the van has high running costs, expensive repairs or a substantial lease payment. It also creates more admin. You need the receipts, invoices and a sensible way to work out private use.

Do not mix the two methods for the same van in the same tax year. If you claim mileage, do not also put through fuel and repairs. If you claim actual costs, do not add a 45p-per-mile claim on top.

How to record van expenses without creating more admin

The best time to record a cost is when you are still standing at the till, not when you are trying to remember what a faded receipt was for in January.

For every van expense, save the receipt or invoice and record the supplier, date, amount, payment method and a short note. “Fuel - travelling to three jobs in Leeds” is far more useful than “Diesel”. For a repair, note the vehicle registration and what work was done, such as “two front tyres” or “alternator replacement”.

If you use actual costs, put each cost into a clear vehicle category. That makes it easier to see what is draining cash. Fuel, repairs and maintenance, insurance, vehicle tax, parking and tolls are usually enough categories for most sole traders. There is no prize for turning a £12 car park payment into an accounting exam.

If you claim mileage, record trips instead of every running cost. A useful mileage entry includes:

• the date of the journey
• the start and finish location
• the job, quote, supplier collection or other business reason
• the number of miles travelled

A trip from home to a regular, permanent workplace may not count as business mileage. Travel between jobs, to a temporary site, to collect materials or to meet a customer is more likely to qualify. Your circumstances matter, so do not assume every mile in a sign-written van is allowable.

Keep business and private use separate

A van can be used mainly for work and still have private use. Taking rubbish to the tip, driving to a family event or doing a mate a favour is not automatically business travel just because the tools are in the back.

The cleanest approach is to build a habit of recording business journeys as you do them. At the end of each month, check the total against the van odometer. This gives you a more believable record than simply writing down an annual mileage total at year end.

For actual costs, work out a reasonable business-use percentage from your mileage log. It does not need to be perfect down to the last mile, but it should be honest, consistent and backed up by records. If private use changes during the year, such as taking on a job closer to home or using the van more at weekends, adjust the percentage rather than forcing the old figure to fit.

Record the bigger costs separately

Buying a van is not the same as filling it with fuel. The tax treatment of the purchase can differ depending on whether you use cash basis accounting, own the van outright, finance it, lease it, are VAT-registered or have private use.

Record the purchase invoice, finance agreement, deposit, monthly payments and any interest separately. Do the same for major upgrades, such as racking, security systems or a tow bar. Some costs may be treated as capital expenditure rather than normal day-to-day expenses, so they may need a different tax treatment.

That does not mean you should ignore them until you speak to an accountant. Get the paperwork recorded now, with a clear description, and deal with the tax treatment when preparing your return. Good records give you options. Missing paperwork does not.

Do not lose the evidence HMRC may ask for

A bank statement proves money left your account. It does not always prove what you bought or whether it was for the business. Keep the receipt, invoice, email confirmation or digital copy alongside the transaction wherever possible.

Paper receipts fade quickly, especially fuel receipts. Photograph them on the day and store the image with the expense. If a receipt is lost, make a note of the date, supplier, amount and what it was for, then keep any card or bank evidence you have. It is better than leaving an unexplained payment in your records, though it is not as strong as the original receipt.

Sole traders normally need to keep business records for at least five years after the 31 January submission deadline for the relevant tax year. That is a long time to rely on a glovebox full of thermal-paper receipts.

Watch the costs that are easy to get wrong

Some van-related spending feels like a business cost but is not allowable. Fines and penalties are the obvious example. You cannot claim a speeding fine because you were late to a job, or a parking penalty because a customer kept you waiting.

Fuel for private journeys must be removed if you use the actual-cost method. Normal commuting can also be a grey area, particularly where you work repeatedly at the same location. If you are unsure, keep a proper journey note and get advice before putting it through as a business expense.

VAT is another area where the receipt matters. If you are VAT-registered, you may be able to recover VAT on qualifying business costs, but private use and the type of expense can affect what you can reclaim. Record the full receipt rather than relying on a rounded figure from your banking app.

Make the van part of your weekly admin routine

A ten-minute Friday check is easier than a four-hour scramble before the tax deadline. Photograph new receipts, log that week’s mileage, and check any van payments that have left the bank. You will spot missed costs while the job is fresh in your mind.

A mobile-first expense tracker is useful here because the record is made from the cab, supplier counter or site gate, rather than waiting for an evening you do not have. TradeTally is built for exactly that kind of admin: capture the receipt, categorise it, and keep your Self Assessment records moving without wading through accounting software.

Your van earns its keep by getting you, your tools and your materials to paid work. Treat its records the same way: keep them current, keep them clear, and tax time becomes one less job waiting for you after a long day.
