Hong Kong Author & Writer Royalty Tax — Expert Advisory

Book royalties received by HK authors are generally assessable as profits from a trade or profession if writing is the author's regular occupation. The income is assessable in the period when the royalties are earned (typically based on the publisher's accounting period for sales). If writing is occasional and non-systematic, royalties may not be assessable as trading income. Most professional authors with multiple works and active writing careers will be assessed on their royalty income as trading profits.

Publisher advances are effectively advance royalty payments — they are earned as the book generates sales against which the advance is recouped. The most defensible tax treatment is to defer recognition of the advance until actual royalties accrue against it. This prevents the entire advance from being taxed as income in the year received when the book may not even be published yet. However, non-returnable advances (retained regardless of sales) may need to be recognised sooner — the contract terms are critical.

Yes. Many countries impose withholding tax on royalties paid to non-residents. The withholding rate depends on the country and any applicable tax treaty. For HK authors receiving royalties from US publishers — 30% withholding under US domestic law (reducible to 0% under some circumstances with a W-8BEN). UK publishers typically withhold at 20% (reducible under treaty). The withheld tax may be creditable against HK profits tax. HK has treaties with 45+ countries that can significantly reduce withholding rates.

Deductible writing expenses include: research books and subscriptions; research travel (flights, accommodation) for project-specific research; writing software (Scrivener, Word, reference management tools); home office expenses (proportionate to writing use area); professional membership fees (Hong Kong Writers Circle, PEN International); agent fees and commissions; marketing and self-promotion costs for independently published books; and computer equipment (capital allowances). Personal reading for general education or enjoyment (not specific to a project) is not deductible.

Yes — translation rights royalties are treated as copyright royalties and are assessable income for professional authors. The sourcing of translation rights royalties may be interesting: if translated by an overseas publisher and sold in overseas markets, there may be an offshore-source argument for the portion attributable to overseas sales. The withholding tax in the country of the translation publisher also applies. Translation rights royalties require the same careful analysis as primary royalties.
