Tax and Self‑Employment for Authors
What you need to know about tax, National Insurance, and keeping records – without the jargon.
Are You Self‑Employed?
If you earn money from your writing, HMRC considers you self‑employed. You need to register for Self Assessment and pay tax on your profits.
Register with HMRC
You must register for Self Assessment by 5 October in your second tax year. It is straightforward – do it online.
Keep Records
Keep track of all income and expenses – receipts, invoices, bank statements. You will need them to fill out your tax return.
Pay Tax and NI
You pay Income Tax on your profits (after expenses) and Class 2 or Class 4 National Insurance if your profits are above the threshold.
What Can You Claim?
You can deduct legitimate business expenses from your income – that reduces your tax bill.
Writing Equipment
Laptops, printers, software, and stationery – if you use them for your writing, you can claim them.
Professional Services
Editing, cover design, formatting, and legal fees – all deductible.
Marketing and Travel
Website costs, advertising, travel to events or readings – claimable if they are for your writing business.
Submitting Your Tax Return
Once a year, you need to submit a Self Assessment tax return online.
Deadlines
File by 31 January each year (for the previous tax year). You can file earlier if you want.
Pay on Time
You pay your tax bill by 31 January. If you owe more than £1,000, you may need to make payments on account.
Get Help
If it feels overwhelming, hire an accountant – they will save you time and often save you money.
When You Are Ready
Tax is not fun, but getting it right gives you peace of mind.
Keep It Simple
Use a simple spreadsheet or accounting software like QuickBooks or FreeAgent.
