Home Baker
Tax & MTD Guide

The tax challenge for a home baker is not a complicated one, but it is an easy one to get wrong. Money comes in as a stream of small payments: a GBP 45 birthday cake paid by bank transfer, GBP 30 of cupcakes sold at a school fair in cash, a wedding deposit taken months before the big day, and a dozen brownie boxes ordered through an Instagram DM. Each sale is small, some are cash, and many never touch a card machine, which is exactly why home bakers most often trip up by under-recording what they actually earned.

This guide is built around how a home baking business really runs: lots of low-value orders, a heavy ongoing ingredient bill, equipment bought gradually, and a kitchen shared with the family. Get into the habit of logging every order and keeping till receipts for flour, butter and boxes, and your Self Assessment return becomes a tidy summary rather than a January panic.

How Tax Works for a Self-Employed Baker

As a sole trader you pay Income Tax on profit, which is your total baking sales 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, while Class 2 NIC is settled through Self Assessment.

Scottish bakers 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 bakers have a C-coded tax code at rates currently matching the rest of the UK. Many home bakers also have a PAYE job, and a second income can quietly distort your tax code, so if yours looks wrong run it through the tax code checker.

The Trading Allowance and Starting Out

Most home bakers begin as a hobby that turned into orders: a few birthday cakes for friends, then friends of friends, then a stall. The GBP 1,000 trading allowance is built for exactly this stage. If your gross baking 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, not just the bit over the threshold.

Once you are over the line 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 ingredient, equipment and kitchen costs if they come to more than GBP 1,000. You cannot do both. Because baking is so ingredient-heavy, most bakers selling regularly will be far better off claiming actual costs, but a baker who made only a handful of cakes from a well-stocked store cupboard may do better with the flat GBP 1,000. Total your costs and pick whichever leaves the lower profit. If you also have wages or another side gig, the multiple-income tax calculator shows how the streams stack together.

Allowable Expenses for Home Bakers

An expense is allowable when it is incurred wholly and exclusively for the business. For a baker the list is dominated by ingredients and consumables, then equipment and a share of home-kitchen running costs.

Ingredients and the Family Shop

Ingredients are your biggest cost and your biggest record-keeping headache, because the butter and eggs for a wedding cake often come from the same Tesco trip as the family dinner. The clean fix is a separate shop, or at least a separate receipt, for business ingredients so you can claim them with confidence. If you genuinely buy in bulk and split a single shop, apportion it on a fair and consistent basis and keep a note of how you worked it out. Do not simply claim the whole household grocery bill, because the private share is never allowable.

Equipment and the Shared Kitchen

A stand mixer, a second oven or a dedicated chest freezer bought for the business is usually deducted in full in the year of purchase under the Annual Investment Allowance. The catch is dual use. A family oven used for the odd order is not wholly and exclusively for the business, so you restrict the claim to the business proportion. For utilities, you can use HMRC's simplified flat-rate working-from-home allowance or claim a fair proportion of the extra gas and electricity your baking actually uses. A heavy baker running ovens for hours often does better calculating the real additional cost, so it is worth doing the sum both ways once and using the larger fair figure.

What You Cannot Claim

The private share of dual-use utilities, equipment and your car must be excluded. Cakes and treats you bake for your own family or eat yourself are not a business cost. Everyday clothing is never allowable, although a branded apron or printed chef's whites used only for work can be. And the cost of getting set up before your baking trade actually started, such as a food hygiene course taken before your first sale, is treated as pre-trading expenditure, claimed once you begin trading rather than lost.

Record-Keeping: The Make-or-Break for Bakers

Because so much baking income is small and some is cash, your records are where tax is won or lost. Log every order as it is agreed, ideally in a simple spreadsheet or your MTD-ready app, with the date, customer, amount and how it was paid. Photograph or save the messages where orders are placed, keep a paying-in record for cash, and bank your takings so there is a trail. On the cost side, keep every till receipt for ingredients and packaging in one place and note your mileage for deliveries and ingredient runs. HMRC can ask to see records for at least five years after the filing deadline, and for a cash-heavy trade like baking, clean contemporaneous records are your best protection.

Worked Example: A Home Baker on GBP 22,000

Take a home baker selling celebration cakes, cupcake boxes and market trays, turning over GBP 22,000 in the year alongside the family kitchen.

Income: GBP 22,000 (custom cakes GBP 12,000, weekly market stall GBP 7,000, online cupcake orders GBP 3,000)

Allowable expenses:

• Ingredients (flour, butter, sugar, chocolate, fondant): GBP 6,800
• Packaging, boxes, boards and consumables: GBP 1,300
• Stand mixer and dedicated oven (AIA, business proportion): GBP 1,400
• Decorating tools and tins: GBP 500
• Home-kitchen utilities proportion: GBP 900
• Food hygiene, public liability and product insurance: GBP 350
• Market pitch fees and delivery mileage: GBP 1,050
• Website, card-reader and listing fees: GBP 400
• Accountancy and bank fees: GBP 300
• Total expenses: GBP 13,000

Taxable profit: GBP 22,000 minus GBP 13,000 = GBP 9,000

Because the profit of GBP 9,000 is below the GBP 12,570 personal allowance, there is no Income Tax and no Class 4 NIC due on the baking trade in this example. The baker still must register, keep records and file a return, and if there is also a PAYE wage or another income stream, that wage may use up the personal allowance so the baking profit is taxed from the basic rate up.

VAT for Home Bakers

You only register for VAT once taxable turnover exceeds GBP 90,000 in any rolling 12-month period, which the overwhelming majority of home bakers never reach. If you do approach it, baking has its own VAT quirks. Most cakes and plain biscuits are zero-rated, which means no VAT is charged, but chocolate-covered biscuits, confectionery, sweets and hot takeaway items can be standard-rated at 20%. The famous Jaffa Cake case turned on exactly this cake-versus-biscuit line. So as you scale, the VAT liability of each product is not obvious and is worth getting checked, because the difference changes both your prices and your margins. Until then, VAT is one less thing for most home bakers to worry about.

MTD for Income Tax: What Changes for Bakers

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 GBP 50,000
• April 2027: Over GBP 30,000
• April 2028: Over GBP 20,000

For a baker the gross-income test matters because baking is low-margin: you might turn over GBP 30,000 in sales while only keeping GBP 12,000 of profit after ingredients, yet it is the GBP 30,000 that counts towards the threshold. The shift to recording each order and ingredient shop digitally as it happens, then sending HMRC a quarterly summary, actually suits a cash-heavy trade well, because capturing sales as they land is far easier than reconstructing a year of orders each January. Our guide to MTD for sole traders walks through what the quarterly rhythm looks like in practice.

Common Mistakes Home Bakers Make

Not recording cash sales. Fairs, markets and friend-of-a-friend orders paid in cash are taxable income just like a bank transfer. Bank your takings and log every one.

Claiming the whole family grocery bill. Only the ingredients used for the business are allowable. Keep business shops or receipts separate and apportion shared shops fairly.

Forgetting to register as a food business. Registering with your local council 28 days before selling is a legal requirement separate from tax, and it is free.

Treating turnover as profit. A baker who turns over GBP 30,000 but keeps GBP 12,000 should set aside tax on the profit, but watch the gross figure for VAT and MTD thresholds.

Assuming a PAYE wage covers the baking too. If a day job already uses your personal allowance, every pound of baking profit is taxed from the basic rate up, so set money aside accordingly.
