Home Bakery Tax UK 2026/27: Kitchen Costs, Ingredients and Equipment
Running a registered home bakery selling cakes, bread and bakes via orders and markets? On £22,000 turnover, typical expenses of around £8,500 bring tax and NI down to roughly £1,700.
A business built on a shared domestic kitchen
A home bakery is unusual among self-employed trades because its main "workshop" — the kitchen — is also where the household cooks its dinner every night. That shared use is what makes use-of-home costs genuinely tricky here, unlike a locksmith's van or a hairdresser's rented chair, which are unambiguously business assets. Everything else about the business is more straightforward: ingredients bought for cake orders or market-stall loaves are a normal cost of sale, and kitchen equipment bought specifically to scale up (a second oven, a spiral mixer, proving drawers) qualifies for full first-year tax relief.

Before selling a single cake, a home baker needs to register the kitchen as a food business with their local council, under the Food Standards Agency's food hygiene rating scheme — this registration itself is free and doesn't need renewing annually. Where cost does come in is training: most bakers take a Level 2 Food Hygiene and Safety course (commonly £15-£30 online, sometimes bundled with an allergen awareness course), and these course fees are a straightforward deductible business expense, as is any paid consultancy to help pass a council hygiene inspection.
Separately, once gross trading income passes £1,000 in a tax year, you must register for Self Assessment with HMRC — below that, the trading allowance covers you and no registration or return is needed.
Worked example: order-based cake business plus market bread stall, £22,000 turnover
Gross income: £22,000 (roughly £14,000 from custom cake orders — birthdays, weddings, celebration bakes — and £8,000 from a weekly farmers' market bread and pastry stall)
Deductible expenses:
- Ingredients (flour, butter, eggs, chocolate, decorations — cost of goods sold): £4,800
- Packaging (cake boxes, bread bags, ribbon, branded stickers): £900
- Food hygiene training course and allergen awareness course: £60
- Kitchen running costs (gas/electricity/water, business-use proportion — see below): £950
- Equipment: second-hand stand mixer and proving baskets (Annual Investment Allowance): £650
- Market stall pitch fees (weekly, 42 weeks): £1,260
- Delivery mileage for cake orders (280 miles at 45p): £126
- Card payment machine and online order platform fees: £340
- Public liability insurance: £180
- Marketing (Instagram ads, local flyers, business cards): £250
- Total expenses: £9,516
Taxable profit: £22,000 − £9,516 = £12,484
Because taxable profit here is below the £12,570 Personal Allowance, no income tax is due at all.
Class 4 NI: profit (£12,484) is below the £12,570 lower profits limit, so no Class 4 NI is due either.
Total tax and NI: £0
Take-home: £22,000 − £9,516 = £12,484
Note there is no Class 2 NI charge at all — it was abolished for the self-employed from 2024/25 onwards, regardless of profit level.

Gross income: £28,000
Deductible expenses:
- Ingredients: £6,200
- Packaging: £1,100
- Food hygiene and food safety training refresher: £40
- Kitchen running costs (business-use proportion): £1,050
- Equipment (replacement oven element, new proving cabinet — AIA): £1,400
- Market stall and event pitch fees: £1,680
- Delivery mileage (600 miles at 45p): £270
- Payment processing and website fees: £420
- Insurance: £190
- Marketing: £350
- Total expenses: £12,700
Taxable profit: £28,000 − £12,700 = £15,300
Income tax: (£15,300 − £12,570) × 20% = £2,730 × 20% = £546
Class 4 NI: (£15,300 − £12,570) × 6% = £2,730 × 6% = £164
Total tax and NI: £710
Take-home: £28,000 − £12,700 − £710 = £14,590
This shows how quickly the numbers shift once profit crosses the Personal Allowance — an extra £2,816 of taxable profit compared with the first example produces £710 of tax and NI rather than nothing, because it's all taxed at the combined 26% marginal rate (20% income tax plus 6% Class 4 NI).
Use of home as kitchen: two ways to apportion costs
This is the area where home bakers most often either under-claim (missing a legitimate deduction) or over-claim (attracting HMRC scrutiny). Two accepted approaches:
| Method | How it works | Best for |
|---|---|---|
| HMRC simplified flat rate | A flat monthly amount based on hours worked from home per month (e.g. £10/month for 25-50 hours, rising for more hours) — no bills apportionment needed | Bakers who bake fewer than ~20-25 hours a week and want simplicity over precision |
| Actual-cost apportionment | Estimate the % of oven/hob hours, and a smaller % of general kitchen electricity/water/heating, used for business vs. private cooking, applied to actual utility bills | Bakers running larger volumes where the flat rate clearly understates real costs (e.g. an oven running most of most days) |
The simplified flat rate only covers utility-type costs — it doesn't include a share of council tax, rent or mortgage interest, and most home bakers don't attempt to claim those anyway, since the kitchen remains a normal domestic room rather than a dedicated business space. Whichever method is chosen, HMRC expects it to be applied consistently year to year, with a reasonable, documented basis (an oven-hours log for a typical week is normally enough evidence).
Equipment and capital allowances
A domestic oven straining under commercial-level order volume, a stand mixer, proving drawers or a second fridge-freezer for storing ingredients and finished bakes are all capital items that typically qualify for the Annual Investment Allowance, meaning the full cost is deducted against profits in the year of purchase rather than spread over several years. For a baker investing £2,500 in a larger commercial-style oven to keep up with wedding cake demand, this produces an immediate, meaningful reduction in that year's tax bill. As with kitchen running costs, if a piece of equipment is also used for ordinary family cooking, only the business-use proportion can be claimed.
Deductible expenses checklist for home bakers
- Ingredients and consumables (cost of goods sold), including reasonable wastage and recipe testing
- Council food hygiene registration (free) and any hygiene/allergen training courses
- Kitchen running costs: business-use share of gas, electricity and water (flat rate or actual-cost method)
- Equipment: ovens, mixers, proving equipment (Annual Investment Allowance)
- Packaging: boxes, bags, ribbon, branded labels
- Market and craft fair stall/pitch fees, gazebo, tablecloths, signage
- Delivery mileage (simplified rate: 45p/mile up to 10,000 miles, 25p after)
- Card payment and online order platform fees
- Public liability insurance
- Marketing and social media advertising
Filing and paying
Register for Self Assessment once gross trading income exceeds £1,000, keep an ingredients and sales log alongside a simple weekly record of oven/kitchen hours for your use-of-home claim, and file online by 31 January following the end of the tax year, paying any income tax and Class 4 NI owed by the same date. Most home bakeries stay well under the £90,000 VAT registration threshold, but it's worth tracking rolling 12-month turnover if markets and wedding orders start to scale up.
self-employed-tax-ukFrequently asked questions
Do I need to register as self-employed to sell cakes from home?
Yes, once your gross income from baking exceeds £1,000 in a tax year, you need to register for Self Assessment with HMRC. Below £1,000 you can use the trading allowance and don't need to register or declare the income at all.
Is food hygiene registration with the council free?
Yes, registering your home as a food business with your local council under the Food Standards Agency scheme is free and has no renewal fee. Any Level 2 Food Hygiene and Safety training course you take (typically £15-£30 online) is a genuine, fully deductible business expense.
Can I claim a proportion of my household bills for baking in my kitchen?
Yes, but it's trickier than a spare-room office because a domestic kitchen is used for both business and private cooking. HMRC accepts a reasonable, consistently-applied proportion of gas, electricity and water based on oven/hob hours used for the business relative to total household use, or you can use HMRC's simplified flat rate instead.
Can I claim the full cost of a new oven or stand mixer in one go?
Yes, via the Annual Investment Allowance, which lets you deduct 100% of the cost of equipment like ovens, stand mixers and proving cabinets against profits in the year of purchase, up to the £1 million AIA limit — provided the item is genuinely used for the business.
What if my oven and kitchen are used for both business and family cooking?
You can only claim the business-use proportion, not the full cost. A common approach is to estimate the percentage of oven hours or kitchen time genuinely spent on paid baking orders versus everyday family meals, and apply that percentage consistently to both running costs and any equipment claimed.
How much tax will I pay on a £22,000 home bakery turnover?
After typical expenses of around £8,500 (ingredients, packaging, hygiene training, a share of kitchen running costs, market stall fees), taxable profit is around £13,500. Income tax and Class 4 NI together come to roughly £1,700, leaving take-home of around £11,800 plus the £8,500 already spent on the business.
Do I need to charge VAT on cakes and bread?
Most cakes and plain bread are zero-rated for VAT, so it doesn't usually change pricing, but you still only need to register for VAT once your taxable turnover exceeds £90,000 in a rolling 12-month period. Below that threshold, registration is optional.
Can I deduct the cost of ingredients even if some bakes don't sell?
Yes — ingredients (cost of goods sold) are deductible as a normal trading expense, including a reasonable amount of wastage, failed bakes and testing new recipes, as long as the overall activity is run as a genuine business rather than a hobby.
Are farmers' market and craft fair stall fees deductible?
Yes, stall or pitch fees at markets, along with any gazebo, table cloths, signage and card payment machine costs used to sell at those events, are all deductible business expenses.
Should I use simplified mileage rates for market and delivery trips?
Many home bakers find HMRC's simplified mileage rate (45p per mile for the first 10,000 business miles, 25p after) easier than tracking actual fuel and running costs, especially since the car is also used privately. Keep a log of dates, destinations and mileage for each delivery or market trip.
