Allowable expenses, the roaster and van, food stock and wastage, VAT, NIC and MTD for Income Tax explained for UK hog roast and event catering sole traders.
Hog roast catering is a cash-rich, seasonal trade with a deceptively simple set of numbers. You quote a price for a wedding, festival or corporate summer party, you buy a pig and a few gas bottles, you tow the roaster to the field, and you carve crackling for a few hours. But the tax sitting behind that day is shaped by three things most caterers underestimate: takings that arrive in lumps and in cash, big one-off equipment outlays, and a VAT threshold that a fully booked summer can blow straight through.
This guide is written for the self-employed hog roast and mobile event caterer working as a sole trader. It covers how your profit is actually taxed, the specific costs you can claim against this trade, the record-keeping that keeps cash takings honest, National Insurance, when VAT starts to matter, and how Making Tax Digital changes the rhythm of your year.
As a sole trader you pay Income Tax on profit, which is your total catering takings minus 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 caterers 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 caterers 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 or an old employment is distorting it, run it through the tax code checker.
Plenty of hog roast caterers start as a weekend sideline, doing a friend's wedding and a couple of village fetes before it grows. The GBP 1,000 trading allowance is built for exactly this. If your gross self-employed takings from all your catering work are GBP 1,000 or less in a tax year, they are tax-free and you do not need to register for Self Assessment for them. Cross GBP 1,000 and you must register and report the full amount, which for any caterer doing even two or three paid events is almost immediate.
Once over the threshold you have a choice each year. You can deduct the flat GBP 1,000 trading allowance instead of working out actual expenses, or you can deduct your real allowable costs if they come to more than GBP 1,000. You cannot do both. For catering this is rarely a close call: a single pig, a gas bottle and a tank of diesel for the van will usually beat GBP 1,000 in a busy season, so most established caterers claim actual expenses. If your catering sits alongside other casual earnings, our guide to side hustle income explains how the allowance interacts with several small trades.
An expense is allowable when incurred wholly and exclusively for the business. Catering is more cost-heavy than most service trades, with real money going out on stock, fuel and kit before a penny of profit is left.
| Expense | What qualifies | Notes |
|---|---|---|
| Hog roast machine and trailer | The roaster itself, towed trailer, spit, gas burners | Capital item, usually claimed in full via the Annual Investment Allowance |
| Marquee, gazebo and stalls | Event shelter, serving counter, prep tables, lighting | Capital allowances on durable kit |
| Prep and serving equipment | Knives, boards, carving tools, trays, chafing dishes, cool boxes, generator | AIA in the year of purchase |
| Food and stock | Whole pigs, baps, apple sauce, stuffing, salads, condiments, drinks for resale | Fully deductible cost of sales |
| Gas and fuel | LPG bottles for the roaster, generator fuel | Ordinary running cost |
| Disposables | Napkins, plates, cutlery, foil, gloves, packaging | Fully deductible |
| Vehicle | Catering van or pickup to tow and transport | Mileage method or actual running costs plus capital allowances, not both |
| Hygiene and PPE | Aprons, hairnets, food-grade gloves, cleaning chemicals, first aid | Protective and hygiene items are allowable; everyday clothing is not |
| Pitch and event fees | Festival pitch fees, market stall rent, commission to venues | Deduct against the takings they relate to |
| Insurance and registration | Public liability, product liability, food hygiene registration, food safety courses | Allowable where required for the trade |
| Marketing | Website, wedding-fair stands, business cards, photos of the spread | Fully deductible running costs |
| Accountancy and bank fees | Bookkeeping, Self Assessment, business banking | Fully deductible |
The two big-ticket items deserve care. A hog roast machine, trailer and serving kit are capital equipment, so rather than appearing as ordinary expenses they are normally written off in full in the year you buy them under the Annual Investment Allowance. Keep the invoice, because this is often your largest single deduction in your first trading year.
The van is the classic trap. You can either claim HMRC's simplified mileage rate (45p a mile for the first 10,000 business miles, 25p after that), which already covers fuel, servicing and wear, or you can claim a business proportion of actual running costs plus capital allowances on the vehicle itself. You must pick one method per vehicle and stick with it. A caterer towing a heavy roaster long distances to events often does better on actual costs, but mileage is simpler and needs only a trip log. Run both once and use the winner; the sole trader tax calculator helps you see the profit impact.
Many caterers prep at home and store the roaster in a garage or yard. You can claim HMRC's flat-rate working-from-home allowance for the admin and prep hours worked at home, or a fair proportion of actual household and storage running costs. Keep it reasonable and evidenced; this is a modest deduction for a caterer, not the centrepiece.
Your own meals while working are not allowable as a normal part of the trade, only genuine subsistence on overnight or unusually distant jobs. Everyday clothing is never allowable even if you buy a smart shirt for weddings, though branded uniform, aprons and protective wear are. The private share of a dual-use van or phone must be excluded, and entertaining clients is not deductible.
Catering is one of the trades HMRC watches for under-declared cash, so clean records protect you as much as they help you. Capture every booking the moment it is confirmed: the deposit, the balance, and any cash taken on the day at a public event. Match each to the supplier costs for that job, so a wedding's takings sit next to the pig, gas and disposables it consumed.
Because takings cluster into the wedding and festival season while costs are spread, set aside a slice of every payment for tax rather than spending a flush July as if it were all profit. A simple rule of thumb is to move 20 to 25% of each payment into a separate pot. If you also have a PAYE job in the quieter months, the multiple-income tax calculator shows how the two stack together.
VAT is where event catering springs a surprise. You must register once your taxable turnover exceeds GBP 90,000 in any rolling 12-month period, and the test is on takings, not profit. A caterer charging GBP 1,000 to GBP 2,000 a wedding and doing two or three events most summer weekends can reach GBP 90,000 quickly, so check your rolling 12-month total every month, not just at year-end.
Most hot, freshly prepared catered food supplied for an event is standard-rated at 20%, so registration means adding VAT to your quotes. For corporate and business clients that is usually painless because they reclaim it, but for private weddings and parties it effectively raises your price or eats your margin. The compensation is that you can reclaim VAT on the van, the roaster, gas, packaging and food stock. If you are approaching the threshold, plan the transition deliberately rather than crashing through it mid-season.
For a hog roast caterer, the danger isn't the pig you forget to claim, it's the cash you forget to record and the VAT line you blow through in a busy summer. Log every booking as it lands and watch your rolling turnover.
Take a sole-trader hog roast caterer with a busy summer season, totalling GBP 46,000 of takings for the year.
Income: GBP 46,000 (weddings GBP 30,000, festivals and fairs GBP 11,000, corporate GBP 5,000)
Allowable expenses:
Taxable profit: GBP 46,000 minus GBP 21,000 = GBP 25,000
Income Tax: GBP 25,000 minus GBP 12,570 = GBP 12,430 at 20% = GBP 2,486
Class 4 NIC: GBP 12,430 at 6% = GBP 746
Total tax and NIC: GBP 3,232 for the year, plus a small Class 2 amount via Self Assessment. Note this excludes the roaster: if the caterer bought a GBP 6,000 machine and trailer this year, the Annual Investment Allowance would knock that straight off profit, cutting the bill further. Run your own figures through the sole trader tax calculator to sanity-check.
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 a caterer this is actually a helpful nudge. Instead of facing a shoebox of pig receipts and a notebook of bookings each January, you record every deposit, balance and supplier cost digitally as it happens and send HMRC a summary every quarter. The seasonality that makes catering returns stressful, with months of frantic takings then a quiet winter, becomes far easier to handle when the numbers are captured continuously. Our guide to MTD for sole traders walks through what the quarterly rhythm looks like in practice.
Not recording cash takings. Public events pay in cash, and undeclared cash is the single biggest risk in this trade. Log every payment, then bank it.
Treating a flush summer as all profit. Takings peak in wedding season while costs are year-round. Set aside tax from every payment so winter does not catch you short.
Missing the VAT threshold. Turnover, not profit, drives VAT, and a busy season can pass GBP 90,000 mid-year. Track your rolling 12-month total every month.
Mixing capital kit with running costs. The roaster and trailer are claimed through the Annual Investment Allowance, while food and gas are ordinary expenses; keep the two separate.
Double-claiming the van. You choose mileage or actual costs per vehicle, not both. Decide once and keep the same method.
