Copywriter & Content Writer

Write off the right expenses and keep more of your writing income.

Allowable Expenses

• Writing Software & Tools — Grammarly Pro, Hemingway App, plagiarism checkers, AI writing assistants, and project management tools.
• Research & Reference Materials — Books, industry journals, online databases, and subscriptions to reference services relevant to your writing niches.
• Home Office Costs — Desk, chair, broadband, and a proportion of utilities if you work from home — use HMRC's £6/week flat rate or calculate actual costs.
• Professional Development — Copywriting courses, CIM membership, NUJ membership, writers' workshops, and relevant training.
• Marketing & Portfolio — Website hosting, domain, email marketing tools, and any advertising to attract new clients.

Tax Tips

• You can deduct the cost of reference materials — books, industry subscriptions, and research tools — as business expenses even if they are also personally interesting.
• If you write for overseas clients, you may need to account for withholding taxes in certain countries — check HMRC's double taxation agreements.
• Use the trading allowance of £1,000 if your writing income is very modest — no need to register or file if you earn below this threshold.
• Record all income, including one-off payments, small platform payouts (Medium, Substack), and barter arrangements.

Frequently Asked Questions

Can I claim books and subscriptions as research costs?

Yes. Books, industry publications, and online subscriptions used for research or to maintain your professional knowledge are deductible, even if they are also of personal interest — provided there is a clear business purpose.

What is the trading allowance and does it apply to me?

The £1,000 trading allowance lets you earn up to £1,000 from self-employment tax-free without needing to register. Above this, you must register and file Self Assessment. Most practising copywriters earn above this threshold.

How do I account for bad debts (unpaid invoices)?

Under the accruals basis, you can claim a bad debt deduction if an invoice has been outstanding for a reasonable period and there is no realistic prospect of payment. Under the cash basis, this issue does not arise as you only declare income when received.

Are AI writing tool subscriptions (ChatGPT Plus, Jasper) deductible?

Yes. AI writing and editing tools used to assist with client work are professional software subscriptions and fully deductible. Keep the billing receipts from ChatGPT Plus, Jasper, Copy.ai, or whichever tools you use for business.
