Tailor & Seamstress Tax UK 2026/27: Alterations, Machines and a £26,000 Example
Self-employed tailors and seamstresses juggle machine costs, fabric stock and a mix of alterations and made-to-measure work. Full worked example on £26,000 turnover shows a £2,046 tax and NI bill.
A trade split between quick alterations and bespoke commissions
Most self-employed tailors and seamstresses run a hybrid business: a steady stream of low-value, quick-turnaround alterations (hemming trousers, taking in a jacket, wedding dress fittings) alongside higher-value made-to-measure commissions that take days of cutting, fitting and finishing. The tax treatment is identical for both — it's all simply trading income — but the expense pattern differs, since bespoke work carries much higher fabric costs per job.

Gross income: £26,000 (a mix of alterations work at £15-£60 per garment and several bridal and made-to-measure commissions through the year)
Deductible expenses:
- Fabric and lining bought for commissions: £2,400
- Thread, zips, buttons, interfacing and other haberdashery: £900
- Sewing machine, overlocker and pressing equipment (capital allowance): £1,600
- Workshop/shop rent and utilities: £1,600
- Public liability insurance: £220
- Marketing (local advertising, website): £350
- Mileage for fittings and fabric-buying trips (600 miles @ 45p): £270
- Total expenses: £7,340
Taxable profit: £26,000 − £7,340 = £18,660
Income tax: (£18,660 − £12,570) × 20% = £6,090 × 20% = £1,218
Class 4 NI: (£18,660 − £12,570) × 6% = £6,090 × 6% = £365
Total tax and NI: £1,583
Take-home: £26,000 − £7,340 − £1,583 = £17,077

A sewing machine, overlocker, industrial iron and steam press, and a dedicated cutting table all qualify as plant and machinery, meaning the full cost is deducted from profit in the year of purchase via the Annual Investment Allowance, rather than depreciated gradually. This matters most if you're upgrading equipment in a strong-profit year — buying a £2,000 industrial overlocker in a year with £30,000+ profit shelters more tax than buying it in a slow year, so timing larger equipment purchases around your expected profit is worth thinking about.
Fabric and stock: cost of goods, not capital
Unlike machines, fabric, lining, interfacing and trims bought for a client's garment are treated as stock — a cost of goods sold, deducted as they're used rather than automatically written off at purchase. For most tailors buying fabric per commission and using it within a few weeks, this distinction barely matters in practice: the cost still lands in roughly the same tax period. It becomes more relevant if you keep a large stock of premium fabrics on hand for a bridal or formalwear specialism, in which case unsold fabric at your accounting year end isn't deducted until it's actually used.
Sole trader vs limited company for a bespoke tailoring business
| Sole trader | Limited company | |
|---|---|---|
| Setup complexity | Minimal — register for Self Assessment | Incorporate at Companies House, separate accounts |
| Tax on £18,660 profit | ~£1,583 income tax + Class 4 NI | Corporation Tax at 19% (small profits rate) = ~£3,545, plus tax on any dividend drawn |
| Admin burden | One Self Assessment return a year | Company accounts, Corporation Tax return, possible payroll |
| Typical fit | Most solo alterations/dressmaking businesses | Larger operations with staff, premises and higher turnover |
For the great majority of solo tailors and seamstresses, sole trader status is simpler and cheaper — limited company structures only start making sense once profit consistently exceeds roughly £35,000-£40,000, where the salary/dividend split can produce a modest tax saving that outweighs the extra admin.
Deductible expenses checklist
- Sewing machine, overlocker, steam press, cutting table (AIA)
- Fabric, lining, interfacing bought per commission (cost of goods sold)
- Thread, zips, buttons and other haberdashery
- Workshop or shop rent, business rates, utilities, or use-of-home if working from a spare room
- Public liability insurance
- Marketing: local advertising, website, social media
- Mileage for fittings, deliveries and fabric-buying trips
Filing and paying
Register for Self Assessment once gross income exceeds £1,000, keep receipts for fabric and haberdashery separate from equipment purchases (the tax treatment differs), and file online by 31 January following the tax year end, paying any income tax and Class 4 NI owed by the same date.
Frequently asked questions
Do I need to register as self-employed for a small alterations business?
Yes, once your gross income from alterations and dressmaking exceeds £1,000 in a tax year. Below £1,000 you can use the trading allowance and skip registration entirely, but most working tailors and seamstresses quickly exceed that threshold and need to register for Self Assessment.
Can I claim my sewing machine and overlocker as expenses?
Yes. Sewing machines, overlockers, sergers, pressing equipment and cutting tables are capital items that typically qualify for the Annual Investment Allowance, giving a 100% deduction against profits in the year you buy them, up to the £1 million AIA limit.
How is fabric stock treated differently from equipment?
Fabric bought specifically for a client's commission or for made-to-measure stock is treated as cost of goods sold, deducted as it's used or sold rather than automatically written off in full on the purchase date. In practice, for most tailors who buy fabric per job and use it within weeks, this makes little difference — the cost still reduces profit in roughly the same period it was incurred.
How much tax does a self-employed seamstress pay on £26,000 turnover?
After typical expenses of around £7,200 (machines, fabric, workshop rent, insurance, thread and haberdashery), taxable profit is roughly £18,800. Combined income tax and Class 4 NI comes to around £2,046.
Can I claim rent on a small shop or workshop unit?
Yes, rent, business rates and utilities on a dedicated alterations shop or workshop unit are fully deductible running costs. If you work from home instead, you can claim a proportion of household costs using either simplified flat-rate mileage-style allowances or a calculated percentage of actual costs.
What if I only do alterations part-time alongside a job?
You still need to register for Self Assessment once income exceeds £1,000, and your alterations profit is simply added to your employment income for income tax purposes — though Class 4 NI is calculated only on the self-employed profit itself, and your Personal Allowance is used against your combined income in the order HMRC applies it.
Are haberdashery items like thread, zips and buttons deductible?
Yes, all consumables used in producing garments — thread, zips, buttons, interfacing, bias binding — are fully deductible business expenses, whether bought in bulk or per job.
Do I need public liability insurance for an alterations business?
It's not legally required for a sole trader working alone, but most tailors and seamstresses carry it anyway, especially if clients visit a shop or workshop for fittings, since it covers damage to a customer's garment or injury on your premises. The premium is a fully deductible expense either way.
Should I register for VAT?
Only once your turnover approaches the £90,000 threshold, which is uncommon for a solo alterations or dressmaking business but realistic for a busy made-to-measure tailor with staff or a bridal specialism. Below that, voluntary registration rarely helps since most clients are individuals who can't reclaim VAT.
Can I claim mileage for delivering finished garments or attending fittings?
Yes, using the simplified mileage rate of 45p per mile for the first 10,000 business miles each tax year (25p thereafter) if you use your own car, covering fittings at a client's home, fabric-buying trips and deliveries.
