If you’re a self-employed tattoo artist, self assessment is something you need to get right. Miss a deadline or file incorrectly and HMRC will issue penalties. Get it right and you’ll only pay the tax you genuinely owe.
Who Needs to File Self Assessment?
You need to complete a self assessment return if your self-employment income exceeds £1,000 in a tax year, you have income from multiple sources not fully taxed through PAYE, or HMRC writes to you requesting a return. Even if you have a part-time employed job alongside tattooing, you’ll likely still need to file.
Key Dates
- 5 October: Register for self assessment if it’s your first time
- 31 January: Online return deadline AND payment of any tax owed
- 31 July: Second payment on account due (if applicable)
Miss the 31 January deadline and you face an automatic £100 fine, with further penalties at 3, 6, and 12 months. Full detail on the penalty regime is at gov.uk/self-assessment-tax-returns/penalties.
What Income Do You Need to Declare?
All income for the tax year must be declared:
- Tattooing income — cash, bank transfer, and card payments
- Tips from clients
- Income from guest spots at other studios
- Income from selling flash art, prints, or merchandise
- Employment income if you also have a PAYE job
Cash income in particular must be declared correctly. HMRC has the power to investigate and cross-reference bank deposits against declared income, so accuracy matters.
What Expenses Can You Deduct?
Your business expenses reduce your taxable profit — everything from needles and ink to studio rental, equipment, training, and professional fees. We cover this in full in our guide to tattoo artist expenses UK.
Payments on Account
Once your annual tax bill exceeds £1,000, HMRC requires advance payments towards the following year’s tax in two instalments: 50% by 31 January and 50% by 31 July. This catches many tattoo artists off guard in their second year of trading. Planning your cash flow around this from the start avoids an unwelcome surprise.
What If You’ve Been Trading and Not Filed?
The best approach is to come forward voluntarily. HMRC treats voluntary disclosure more leniently than cases where they identify unreported income first. You can notify HMRC of unpaid tax using the HMRC self assessment registration system and get things regularised properly.
