Ceramicist
Tax & MTD Guide

A ceramicist's tax position looks nothing like a desk-based freelancer's. You are running a making trade with genuine physical costs: bags of stoneware clay, buckets of glaze, oxides and stains, kiln firings that drink electricity, and capital kit like a kiln and a wheel that can run into thousands. Income arrives unevenly too, from studio sales, craft fairs and markets, gallery consignment, an Etsy or Shopify shop, commissions, and the odd teaching workshop. The art of getting your Self Assessment right is matching all of that material and firing cost against the right income so you are taxed only on real profit.

This guide is built around how a potter actually works: the materials and stock that flow through the studio, the kiln and equipment that count as capital, the firing and studio overheads that quietly dominate the expense list, and the choice between cash and accruals accounting that decides whether you ever have to value a shelf of unsold mugs.

How Tax Works for a Self-Employed Ceramicist

As a sole trader you pay Income Tax on profit, which is your total pottery income 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 potters 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 makers 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 teaching job or a PAYE role is distorting it, run it through the tax code checker.

The Trading Allowance and Selling Your First Pots

Many potters start by selling at a local market or to friends while holding down another job. The GBP 1,000 trading allowance is built for exactly this. If your gross income from selling ceramics across all channels 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, even if pottery is a sideline.

Once you are over the threshold you choose 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 a working potter the actual-cost route almost always wins, because clay, glazes and especially firing electricity usually swamp GBP 1,000 well before you have sold much. Keep the receipts and claim the real figure.

Materials, Stock and the Cash Basis

This is where a making trade differs sharply from a service trade. Clay, glazes, oxides, slips, underglazes, packaging and postage materials are raw materials and consumables, all fully deductible against profit. The question is when you get the deduction, and that depends on your accounting method.

For most studio potters the cash basis is the sensible choice: you count the money that came in from sales and the money that went out on clay, glazes and firings, and you never have to count a shelf of unsold mugs at midnight on 5 April. If you carry a lot of stock, sell to galleries on consignment with long payment delays, or supply trade buyers on credit, the accruals basis can give a truer picture and may be worth the extra bookkeeping. Use the sole trader tax calculator to see how a given profit figure translates into tax and NIC either way.

Allowable Expenses for Ceramicists

An expense is allowable when incurred wholly and exclusively for the business. A potter's list is dominated by materials, firing and studio costs, with significant capital spend on the kiln and wheel.

Kiln and Equipment: Capital, Not Day-to-Day

The big spend in pottery is capital. A new electric kiln, a potters wheel, a slab roller or a pug mill are assets, not consumables, and you normally claim them in full in the year of purchase through the Annual Investment Allowance. A second-hand kiln bought for the business qualifies just as well. Where a piece of kit is also used privately, you claim only the business-use proportion. The ongoing costs around the kiln, replacement elements, shelves, props, stilts and servicing, are ordinary running expenses you deduct as you incur them.

Firing Costs and the Home Studio

Firing is the hidden giant of a potter's expense list. A single bisque-then-glaze cycle in an electric kiln can use a serious amount of electricity, and over a year it often outweighs the clay itself. If you fire in a dedicated rented studio, the electricity or gas is straightforwardly deductible. If you fire at home, you can either use HMRC's simplified flat rate based on hours worked from home, or claim a fair actual proportion of household power, heat and light reflecting the studio space and kiln use. Because a kiln is so power-hungry, a home-based potter is often much better off metering or reasonably apportioning actual electricity than relying on the modest flat rate. Work it out both ways once and use the larger figure.

What You Cannot Claim

The private share of any dual-use cost, your home broadband, a phone you also use personally, or a vehicle used for the school run as well as deliveries, must be excluded. Everyday clothing is never allowable, even an apron you happen to wear elsewhere, although genuine PPE such as a glaze respirator is fine. Pots you make and keep for yourself, or gift, are not a deductible cost. And entertaining buyers is not allowable, even when it lands you a gallery order.

Worked Example: A Ceramicist on GBP 32,000

Take a maker selling through a studio shop, two craft fairs a season, a gallery on consignment and an online store, with GBP 32,000 of sales for the year and using the cash basis.

Income: GBP 32,000 (markets and studio sales GBP 17,000, online GBP 9,000, gallery sales net of commission GBP 6,000)

Allowable expenses:

• New electric kiln and wheel (AIA, claimed in full): GBP 4,200
• Clay, glazes, oxides and packaging: GBP 3,100
• Firing electricity and kiln furniture: GBP 1,900
• Studio share of rent and insurance: GBP 1,800
• Craft fair pitches, online and card fees, gallery commission: GBP 1,400
• Photography, website and marketing: GBP 500
• Accountancy and bank fees: GBP 400
• Total expenses: GBP 13,300

Taxable profit: GBP 32,000 minus GBP 13,300 = GBP 18,700

Income Tax: GBP 18,700 minus GBP 12,570 = GBP 6,130 at 20% = GBP 1,226

Class 4 NIC: GBP 6,130 at 6% = GBP 368

Total tax and NIC: GBP 1,594 for the year. The kiln purchase is what makes this year's bill so low; in a later year without a big capital buy the profit, and the tax, would be higher. If you also have a part-time teaching wage or another stream, run the combined figures through the multiple-income tax calculator so the streams stack correctly.

Multiple Income Streams

A maker's money rarely comes from one place, and the streams are not all taxed the same way.

The recurring mistake is assuming a salaried job's personal allowance still shelters your pottery. If PAYE already uses your GBP 12,570, every pound of pottery profit is taxed from the basic rate up, so set money aside accordingly.

VAT for Ceramicists

You must register for VAT once taxable turnover exceeds GBP 90,000 in any rolling 12-month period, which most studio potters never approach. If you do reach it and you supply galleries, shops or trade buyers who are VAT-registered, they reclaim the VAT you charge and you reclaim VAT on clay, kilns and firing, so registration is relatively painless. A potter selling mainly to consumers at markets and online should weigh it carefully: adding 20% to a retail price either eats your margin or raises your price, so voluntary registration only makes sense when your customers can reclaim the tax.

MTD for Income Tax: What Changes for Potters

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 maker this is a change of habit. Instead of pulling a shoebox of fair receipts and bank statements together each January, you record each sale, each clay order and each firing digitally as it happens and send HMRC a summary every quarter. The upside is that the uneven, multi-channel income that makes pottery returns fiddly becomes much easier to manage when captured continuously. Our guide to MTD for sole traders walks through what the quarterly rhythm looks like in practice.

Common Mistakes Ceramicists Make

Not registering once over GBP 1,000. The trading allowance is a threshold, not a free pass at any level. Cross it and you must register for Self Assessment, even if potting is a hobby that started paying.

Treating the kiln as a running cost. A kiln is a capital asset claimed through the Annual Investment Allowance, not an everyday expense; logging it wrongly distorts your accounts.

Under-claiming firing electricity. Kilns are power-hungry, and a home-based potter who relies on the small flat-rate home-working allowance often leaves a real deduction on the table.

Recording sales net of fees. Report the gross sale and deduct gallery commission, market pitch fees and online charges separately, so your figures reconcile.

Assuming a PAYE allowance covers pottery too. If a day job already uses your personal allowance, your making profit is taxed from the basic rate up, so set aside more than you expect.
