Ghostwriter Self-Employed Tax Guide UK (2026/27)
How self-employed ghostwriters in the UK are taxed on book fees, NDAs and rights transfers, plus which expenses — research, software, courses — are allowable in 2026/27.
How Ghostwriting Income Is Taxed
A self-employed ghostwriter's income — book fees, memoir project payments, corporate or public-figure writing commissions, and any contracted share of royalties — is trading income for Income Tax and Class 4 National Insurance purposes, reported through Self Assessment in the normal way.

Model self-employed profit and taxAllowable Expenses for Ghostwriters
Common allowable costs include:
- Research materials, books and paid subscriptions bought for a specific commission
- Transcription and interview recording services
- Writing and project-management software subscriptions
- A proportion of home-working costs, using HMRC's simplified flat rates or apportioned actual costs
- Professional memberships (for example, the Society of Authors) where relevant to the trade
The Trading Allowance Option
Ghostwriters with relatively low costs can claim the £1,000 trading allowance instead of itemising expenses, which is often the simpler route in a quiet year. Once genuine expenses — software, courses, a proportion of home costs — exceed £1,000, itemising actual expenses is usually the better outcome.

Frequently asked questions
How is a ghostwriter's income taxed?
Fees for writing work — whether a flat project fee, a day rate, or a share of royalties assigned under contract — are ordinary self-employed trading income, taxed through Self Assessment via Income Tax and Class 4 National Insurance in the same way as any other freelancer's profits.
Can a ghostwriter claim for research materials and books?
Yes, books, research subscriptions, interview transcription services and similar materials bought specifically for a commissioned project are allowable business expenses, deducted from profits before tax.
Is client confidentiality relevant to ghostwriting tax at all?
Not directly — HMRC taxes the income and allowable expenses in the normal way regardless of NDAs or anonymity clauses in a contract. What matters for tax purposes is the substance of the work and payment, not whether the writer's name appears on the finished book.
Can a ghostwriter use the £1,000 trading allowance instead of claiming actual expenses?
Yes — anyone with self-employed income can choose to deduct the £1,000 trading allowance instead of itemising actual expenses, which is often simpler for a ghostwriter with modest costs in a quiet year, though claiming actual expenses is usually better once genuine costs (courses, software, a portion of home costs) exceed £1,000.
Are ghostwriting royalties taxed differently from a flat fee?
No — both flat fees and any royalty share received under a ghostwriting agreement are trading income for a self-employed ghostwriter, taxed in the tax year they are received (or earned, depending on the accounting basis used), not given special tax treatment because they're structured as royalties.
Could averaging relief for creative artists apply to a ghostwriter?
Potentially — averaging relief is aimed at self-employed creators of original literary works, and a ghostwriter who is the actual author of the text may qualify if profits fluctuate significantly year to year, though this depends on the specific facts and is worth checking with an accountant.
