Allowable expenses, stall and pitch fees, cash record-keeping, NIC, VAT and MTD explained for UK self-employed market traders.
The tax challenge for a market trader is not complexity, it is cash. A fruit-and-veg or general stall takes hundreds of small payments a day, much of it in notes and coins, buys stock at the wholesale market before dawn, pays a pitch fee to the market operator, and runs a van to haul it all. Margins are thin, volume is high, and almost nothing generates a tidy digital paper trail unless you build one. That makes record-keeping, not clever reliefs, the thing that decides whether your Self Assessment is painless or a nightmare.
This guide is built around how a stall actually runs: cash takings and how to record them, stock as cost of sales, the pitch fees, van and equipment that make up your deductions, and the VAT quirks of selling food. Get the daily takings discipline right and the rest falls into place.
As a sole trader you pay Income Tax on profit, which is your total takings minus the cost of stock sold and your other allowable expenses. For 2025/26 the personal allowance covers the first GBP 12,570, then you pay 20% to GBP 50,270, 40% to GBP 125,140 and 45% above, with the personal allowance tapering away between GBP 100,000 and GBP 125,140 to create an effective 60% band. Class 4 National Insurance is 6% on profit between GBP 12,570 and GBP 50,270 and 2% above, with Class 2 NIC settled through Self Assessment.
Scottish traders pay Scottish Income Tax on their profit through six bands (19%, 20%, 21%, 42%, 45% and a 48% top rate) and carry an S-prefixed tax code, while National Insurance stays UK-wide. Welsh traders have a C-coded tax code at rates currently matching the rest of the UK. If your code looks wrong, perhaps because a part-time PAYE job alongside the stall is distorting it, run it through the tax code checker.
Plenty of traders start with a single weekend pitch to test the water. The GBP 1,000 trading allowance is built for exactly this. If your gross stall takings for the whole year are GBP 1,000 or less, the income is tax-free and you do not need to register for Self Assessment for it. Cross GBP 1,000 and you must register and report the full takings.
Once you are over the threshold you have a choice each year. You can deduct the flat GBP 1,000 trading allowance from your takings instead of working out actual costs, or you can deduct your real allowable expenses if they come to more than GBP 1,000. You cannot do both. For most market traders the allowance is irrelevant after the first few weeks, because the cost of stock alone dwarfs GBP 1,000, so you will almost always claim actual expenses and account for stock properly.
This is the single most important section for a market trader. HMRC knows cash businesses are where income goes unrecorded, so a trader with sloppy records is far more likely to face an enquiry, and far less able to defend their figures when one comes.
The golden rules are simple but unforgiving. Cash up at the end of every single market and write down the total takings, separating cash from card, before you spend a penny. Keep your card-reader (such as SumUp, Zettle or Square) statements, which give an independent record of part of your income. Bank your cash in regular, traceable amounts rather than spending it straight from the tin, and never buy stock or pay a pitch fee out of unrecorded cash, because doing so understates both income and costs and makes your margin look wrong. A consistent set of daily totals that ties back to your bank and card reports is what makes your return defensible.
Stock is not just an expense, it is accounted for differently, and getting this wrong is a common error. You deduct the cost of goods you actually sold during the year, not simply everything you bought. That means counting your stock at the start and end of the year:
Cost of sales = opening stock + purchases during the year − closing stock
So if you began the year with GBP 500 of stock, bought GBP 30,000 over the year and had GBP 800 of unsold stock on the shelves at year end, your cost of sales is GBP 29,700. For perishable goods such as fruit and veg, closing stock is usually small, but you must still do an honest count. Keep every wholesale invoice and cash-and-carry receipt, as these are the backbone of your largest deduction.
An expense is allowable when incurred wholly and exclusively for the business. For a stall the list is dominated by stock, pitch and transport rather than office costs.
| Expense | What qualifies | Notes |
|---|---|---|
| Stock and wholesale purchases | Goods bought to resell, accounted for as cost of sales | Keep every invoice and cash-and-carry receipt |
| Market pitch and licence fees | Daily or weekly pitch rent, council market licence, casual trading consent | Get receipts from the market operator |
| Van and travel | Mileage at 45p/25p, or actual running costs, fuel, insurance, MOT, repairs | Choose simplified mileage or actuals and stick with it |
| Stall equipment | Gazebo, tables, trestles, scales, chiller boxes, display units, the float | Capital items via the Annual Investment Allowance |
| Packaging and consumables | Carrier bags, paper bags, punnets, wrapping, till rolls, labels | Fully deductible running costs |
| Protective clothing | Aprons, gloves, hi-vis, waterproofs and branded uniform | Everyday clothing is never allowable |
| Insurance | Public liability, stock and equipment cover | Essential for most market operators |
| Card-reader and bank fees | SumUp, Zettle or Square transaction fees, business banking | Deduct the fees, report takings gross |
| Accountancy | Bookkeeping and Self Assessment preparation | Fully deductible |
Most traders run a van to move stock. You can use HMRC's simplified mileage rate (45p a mile for the first 10,000 business miles, then 25p) which needs only a mileage log, or you can claim a business proportion of actual running costs including fuel, insurance, road tax, MOT and repairs, plus capital allowances on the van itself. You cannot mix the two methods on the same vehicle, so work out which gives the bigger deduction for your mileage and stick with it. Travel between home and the market counts as business travel for a trader with no fixed business premises.
Your own food and drink on a trading day is not allowable, even on a long market day, because everyone has to eat. Everyday clothing is never deductible even if you only wear it to trade. The private share of a dual-use van, phone or broadband must be excluded. And stock you took home for personal use must be added back as own consumption, valued at cost, rather than quietly left in cost of sales.
Take a fruit-and-veg trader working three markets a week, with GBP 45,000 of gross takings for the year.
Takings: GBP 45,000
Cost of sales: opening stock GBP 400 + purchases GBP 26,000 − closing stock GBP 400 = GBP 26,000
Other allowable expenses:
Taxable profit: GBP 45,000 − GBP 26,000 − GBP 9,900 = GBP 9,100
Because the profit here sits below the GBP 12,570 personal allowance, there is no Income Tax and no Class 4 NIC for the year, which is typical of a low-margin stall, where high takings translate into modest profit. The trader may still choose to pay voluntary Class 2 NIC through Self Assessment to protect their State Pension record. Run your own figures through the sole trader tax calculator to see where your profit lands, and the multiple-income calculator if you also have a job or other income.
For a market trader, the takings you forget to record cost you far more than the receipts you forget to keep. Cash up the same way after every market and your return looks after itself.
You must register for VAT once taxable turnover exceeds GBP 90,000 in any rolling 12-month period. Busy traders on several markets a week can reach this sooner than they expect, so watch your rolling 12-month total rather than the tax year. The wrinkle for food traders is that most unprepared food, including fresh fruit and vegetables, is zero-rated: you charge 0% VAT on sales but can still reclaim the VAT you pay on van fuel, packaging, equipment and other costs. That makes registration genuinely worthwhile for many food stalls rather than a burden. Hot food, prepared food eaten on the go, and most non-food goods are standard-rated at 20%, so a mixed stall needs to keep its VAT categories straight. If you sell standard-rated goods mainly to consumers, adding 20% can hurt your price, so weigh it carefully.
Making Tax Digital for Income Tax Self Assessment replaces the once-a-year return with quarterly digital submissions and a year-end finalisation. The thresholds are based on gross income, not profit:
For market traders this matters more than it looks, because the test is on gross takings. A low-margin food stall can turn over GBP 50,000 while making a fraction of that in profit, yet still be pulled into MTD on the turnover figure. The upside is that the daily takings discipline you already need translates neatly into digital record-keeping: log each day's takings and your wholesale invoices as you go, and the quarterly summary is mostly automatic. Our guide to MTD for sole traders walks through what the quarterly rhythm looks like in practice, and if the stall is a sideline alongside a job, side-hustle income covers how it stacks on top.
Under-recording cash takings. The biggest risk by far. Without a reliable daily takings record, HMRC can estimate your income upward in an enquiry, and you have little to argue back with.
Treating all stock purchases as the year's expense. You deduct cost of sales, not everything bought, so you must count opening and closing stock rather than expensing the full purchase ledger.
Paying for stock out of the cash tin without recording it. This understates both your takings and your costs, distorts your margin and is a classic enquiry trigger.
Forgetting own consumption. Stock you take home to eat must be added back at cost, not left in cost of sales as if it were sold.
Watching the tax year for VAT instead of the rolling 12 months. The GBP 90,000 test is a rolling total, and a multi-market trader can cross it mid-year without noticing.
