Allowable expenses, ingredients and equipment, home-kitchen costs, VAT on cakes, Self Assessment and MTD explained for UK self-employed cake makers and home bakers.
A cake-making business runs on tight margins and heavy costs. Every order eats through flour, butter, sugar, eggs, fondant, boards, boxes and hours of oven time, and the equipment bill, from a decent stand mixer to a fridge, tins and a delivery vehicle, adds up fast. Unlike a desk-based freelancer whose costs are small, a cake maker's tax bill is shaped almost entirely by how thoroughly they capture expenses. Forget to log the ingredients and the failed practice bakes and you will hand HMRC tax on money you never really kept.
This guide is built for how cake makers actually trade: a home or small commercial kitchen, a stream of birthday and celebration orders, a seasonal spike around weddings and Christmas, and a pile of receipts from the cash-and-carry. Get the record-keeping right as the orders come in and the annual return becomes a tidy formality.
As a sole trader you pay Income Tax on profit, which is your total cake sales minus allowable expenses, not on turnover. 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 bakers pay Scottish Income Tax on 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 bakers have a C-coded tax code at rates currently matching the rest of the UK. If you also have a PAYE job, perhaps baking around part-time work, your tax code may already use your personal allowance; check it with the tax code checker so you set aside the right amount on your cake profit.
Many cake makers begin by baking for friends, then for friends of friends, before it quietly becomes a business. The GBP 1,000 trading allowance is the line. If your gross cake-making income from all sales is GBP 1,000 or less in a tax year, it 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 amount.
Once over the threshold you choose each year between deducting the flat GBP 1,000 trading allowance instead of working out expenses, or deducting your real allowable costs. You cannot do both. For most cake makers, actual expenses easily beat GBP 1,000 once you add up ingredients, packaging, equipment and kitchen overheads, so keep your receipts and claim actuals. The flat allowance only wins for the smallest, occasional baker with almost no outlay. Our side-hustle income guide covers the move from hobby to declared trade.
Separately from tax, anyone selling food made at home must register as a food business with their local council, normally at least 28 days before trading. It is free, but it is a legal must, and the compliance costs that follow are deductible.
An expense is allowable when incurred wholly and exclusively for the business. For a cake maker the list is dominated by consumables, equipment and kitchen running costs.
| Expense | What qualifies | Notes |
|---|---|---|
| Ingredients | Flour, sugar, butter, eggs, fondant, chocolate, food colouring, flavourings | Include wastage from failed and practice bakes |
| Packaging | Cake boxes, boards, drums, dowels, ribbon, cellophane, bubble wrap | A direct cost of every order |
| Baking equipment | Stand mixer, oven, fridge or freezer, tins, turntables, piping kit, scales | Claimed via the Annual Investment Allowance, usually in full |
| Small tools and consumables | Palette knives, nozzles, baking parchment, cleaning products | Fully deductible running costs |
| Home-kitchen running costs | A fair share of electricity, gas and water used for baking | Apportion by use; ovens are heavy on power |
| Insurance | Public and product liability insurance for selling food | Allowable in full |
| Food hygiene and compliance | Level 2 Food Hygiene certificate, allergen training, council registration | Allowable training and compliance costs |
| Delivery and travel | Mileage to deliver cakes, stall and market pitch fees | Use the 45p/25p flat mileage rate or actual vehicle costs |
| Marketing and sales | Website, Instagram ads, business cards, photography of your cakes | Portfolio photos are a genuine business cost |
| Card and platform fees | Card-machine, Stripe or marketplace commission | Deduct the fee, report income gross |
| Accountancy and bank fees | Bookkeeping, Self Assessment, business banking | Fully deductible |
Ingredients are your biggest recurring cost and the easiest to under-claim because they are bought in bits from supermarkets and the cash-and-carry. Keep every receipt and log it against the business, including the eggs you cracked for a test sponge that flopped. Wasted ingredients from failed or practice bakes are still a real business cost and remain deductible.
Working from a home kitchen, you cannot use HMRC's simplified working-from-home flat rate in the same way an office worker would, because that rate is designed for desk hours, not energy-hungry baking. Instead, claim a fair, reasonable proportion of the household electricity, gas and water actually used for the business. Be honest and keep a note of how you arrived at the figure: a baker running a domestic oven for hours most days can justify a meaningful slice of the energy bill, but it must reflect genuine business use, not the whole household.
The private share of dual-use costs must be excluded: the cake you bake for your own family, the proportion of the fridge used for household food, and personal grocery shopping mixed in with ingredients. Everyday clothing is never allowable, though a branded apron, hairnet and food-safe gloves are. The full cost of a new family kitchen is not a cake-business expense, even if you bake in it; only equipment bought specifically for the business qualifies.
Cake makers buy real kit, a stand mixer, a second oven, a display fridge, a stack of tins and turntables, sometimes a small van. Most of this qualifies for the Annual Investment Allowance, which lets you deduct the full cost of qualifying equipment in the year you buy it rather than spreading it over years. For a baker investing in a big mixer or commercial oven, that can wipe out a large chunk of a profitable year's tax. Keep the invoices, and if an item is part-personal (a fridge used for both family food and cake fillings) claim only the business share.
Take a home-based cake maker with steady celebration orders and a busy wedding season, turning over GBP 34,000 of sales for the year.
Income: GBP 34,000 (celebration cakes GBP 21,000, wedding cakes GBP 11,000, market stall GBP 2,000)
Allowable expenses:
Taxable profit: GBP 34,000 minus GBP 17,500 = GBP 16,500
Income Tax: GBP 16,500 minus GBP 12,570 = GBP 3,930 at 20% = GBP 786
Class 4 NIC: GBP 3,930 at 6% = GBP 236
Total tax and NIC: GBP 1,022 for the year. The headline turnover of GBP 34,000 looks like a lot to be taxed on, but because cake making carries such heavy costs the actual bill is modest, which is exactly why disciplined expense tracking matters. Run your own figures through the sole trader tax calculator, and if you also have a PAYE job or rental income use the multiple-income calculator to see how the streams stack.
For a cake maker, the tax you overpay usually comes from the receipts you never kept. Log every bag of flour, every box, every delivery mile and every failed practice bake as it happens, and you only pay tax on what you actually earned.
Cakes are zero-rated for VAT as food, which is unusually good news. You must still register once taxable turnover exceeds GBP 90,000 in any rolling 12-month period, but once registered you charge 0% VAT on standard cakes while reclaiming the VAT you pay on ingredients, equipment, packaging and overheads. That can put a high-turnover cake business in a VAT-repayment position rather than a paying one, so registering is often worth it for a larger operation.
The catch is the borderline. Not everything a cake maker sells is a zero-rated cake. Chocolate-covered biscuits, some confectionery and sweets, and food sold to be eaten on the premises (for example at a market café table) can be standard-rated at 20%. If you branch into brownies-as-biscuits, sweets or hot drinks, check the liability of each line rather than assuming everything is zero-rated.
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 cake maker the key trap is that the test is turnover, not the thin profit you actually keep. A strong wedding season or a few large corporate orders can push gross sales over a threshold even when your margins are slim, bringing you into MTD sooner than you would guess from your take-home. The upside is that capturing each order and ingredient receipt digitally as you go suits a busy kitchen far better than a January receipt-hunt. Our guide to MTD for sole traders walks through what the quarterly rhythm looks like in practice.
Not registering once over GBP 1,000. The trading allowance is a threshold, not a free pass. Cross it and you must register for Self Assessment, even if baking is a weekend sideline.
Under-recording ingredients. Buying flour, butter and fondant in dribs and drabs from supermarkets makes it easy to lose track. Those receipts are your single biggest deduction.
Forgetting wastage and practice bakes. The ingredients in a cake that collapsed or a sample for a wedding tasting are still a deductible business cost.
Over-claiming the home kitchen. You can claim a fair share of energy for baking, but not the whole household bill or the cost of a new family kitchen.
Confusing turnover with profit for MTD and VAT. Both the MTD thresholds and the GBP 90,000 VAT line are tested on gross sales, so a high-turnover, low-margin baker can be caught earlier than expected.
