The rule behind every claim

Every expense must be incurred wholly and exclusively for the purpose of your tattooing business. That's HMRC's test. If something was bought partly for personal use and partly for work, you can usually claim the business proportion — but you need to record how you calculated that split.

Consumables

Typically the largest expense category and the most straightforward to claim.

Allowable:

Keep supplier invoices. Online orders are especially easy — your order history is a ready-made record.

Equipment

Equipment bought for your work can be claimed in full in the year of purchase under HMRC's Annual Investment Allowance. This covers:

There's no upper limit on AIA for most sole traders, so the full cost is deductible in the year of purchase rather than spread over years.

Studio rent and chair fees

Whether you pay a fixed weekly fee, a daily rate, or a percentage of earnings to a studio owner, these costs are allowable. Keep the evidence: a rental agreement, invoices from the studio, or bank statements showing the payments. Even an informal arrangement (cash in an envelope) can be claimed — you just need to be able to demonstrate what you paid and when.

Hygiene and PPE

These are clearly for business use only:

Portfolio and marketing

Building your professional presence is a legitimate business cost:

Your personal social media account isn't directly claimable, but paid-for promotion on those platforms is.

Training and professional development

HMRC allows training costs that develop or maintain existing skills in your current trade:

What doesn't qualify: a course that retrains you for an entirely different trade. The skill has to be relevant to your tattooing business.

Travel

If you travel for work — guest spots at other studios, conventions, client visits — you can claim:

Your regular journey from home to your usual studio is ordinary commuting and cannot be claimed. Travel to a different location from your normal place of work can be.

What you cannot claim

Normal clothing. Clothing you could wear outside work doesn't qualify, even if you'd only ever wear it for sessions. Genuine PPE (gloves, masks) is allowable; a black t-shirt isn't, even if you wear it exclusively at work.

Client entertaining. Taking a client for food or drinks is explicitly disallowed under UK tax law.

Personal items with a work excuse. An iPad claimed as a "reference tool" needs to hold up to scrutiny. If you genuinely use it for work — displaying flash designs, running your booking system — you can claim the business proportion. If it's primarily personal, it's not allowable.

Record keeping

You don't submit receipts with your return, but HMRC can ask for them during an enquiry (up to four years after filing). A simple system that works: keep supplier invoices either digitally or in a folder, note the business purpose on anything that's not obviously work-related, and log mileage as you travel.

The more organised your records during the year, the faster your January return becomes.
