Key takeaways
  • A market stall is a cash-heavy, high-turnover, low-margin trade, so the biggest tax risk is under-recording takings rather than missing expenses; HMRC scrutinises cash businesses closely.
  • If your gross takings top £1,000 you must register for Self Assessment; below that the trading allowance covers you, and you can deduct the £1,000 allowance instead of expenses if it gives a lower profit.
  • Stock, pitch and licence fees, van running costs and stall equipment are the core deductions, and stock is accounted for as cost of sales with an opening and closing stock count.
  • VAT can bite earlier than expected because the £90,000 threshold is on gross turnover, but zero-rated fresh food means many food traders benefit from registering.
  • MTD for Income Tax applies from April 2026 above £50,000, April 2027 above £30,000, and April 2028 above £20,000, and the test is on gross takings not profit, so a high-turnover stall is caught easily.

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.

How Tax Works for a Self-Employed Market Trader

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 2026/27 the personal allowance covers the first £12,570, then you pay 20% to £50,270, 40% to £125,140 and 45% above, with the personal allowance tapering away between £100,000 and £125,140 to create an effective 60% band. Class 4 National Insurance is 6% on profit between £12,570 and £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.

The Trading Allowance and Starting Out

Plenty of traders start with a single weekend pitch to test the water. The £1,000 trading allowance is built for exactly this. If your gross stall takings for the whole year are £1,000 or less, the income is tax-free and you do not need to register for Self Assessment for it. Cross £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 £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 £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 £1,000, so you will almost always claim actual expenses and account for stock properly.

Cash Takings: Record-Keeping That Survives a Check

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.

Daily gross takings record
A contemporaneous record of the total money taken each trading day, made up of cash counted from the float plus card-reader settlements. HMRC expects market traders to cash up at the end of every market and record the day's gross takings before any money is spent or banked. A reliable daily takings book or app, backed by card-machine reports and banking that matches, is the evidence that your declared profit is complete and correct.

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 as Cost of Sales

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 £500 of stock, bought £30,000 over the year and had £800 of unsold stock on the shelves at year end, your cost of sales is £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.

Allowable Expenses for Market Traders

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.

Stock and wholesale purchasesGoods bought to resell, accounted for as cost of salesKeep every invoice and cash-and-carry receipt

AccountancyBookkeeping and Self Assessment preparationFully deductible

Van and Mileage in Detail

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.

What You Cannot Claim

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.

Worked Example: A Market Trader on £45,000 Takings

Take a fruit-and-veg trader working three markets a week, with £45,000 of gross takings for the year.

Takings: £45,000

Cost of sales: opening stock £400 + purchases £26,000 − closing stock £400 = £26,000

Other allowable expenses:

  • Market pitch and licence fees: £4,200
  • Van running costs (simplified mileage): £2,400
  • Packaging, bags and till rolls: £900
  • Stall equipment (gazebo, scales, chiller, via AIA): £1,200
  • Public liability insurance: £350
  • Card-reader and bank fees: £450
  • Accountancy: £400
  • Total other expenses: £9,900

Taxable profit: £45,000 − £26,000 − £9,900 = £9,100

Because the profit here sits below the £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.

VAT for Market Traders

You must register for VAT once taxable turnover exceeds £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.

MTD for Income Tax: What Changes for Traders

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:

  • April 2026: Combined trading and property income over £50,000
  • April 2027: Over £30,000
  • April 2028: Over £20,000

For market traders this matters more than it looks, because the test is on gross takings. A low-margin food stall can turn over £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.

Common Mistakes Market Traders Make

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 £90,000 test is a rolling total, and a multi-market trader can cross it mid-year without noticing.

Quarterly expenses under MTD: the £90,000 rule

If your annual business turnover is £90,000 or less, HMRC lets you report a single consolidated expenses total in each Making Tax Digital quarterly update instead of breaking expenses down into itemised categories. Most self-employed market trader businesses are under this threshold, so a quarterly update can be as simple as two figures: total income and total expenses. You still need to keep digital records of each individual expense - the relaxation only changes how much detail goes into the quarterly update itself.
