You Can Legally Pay Less Tax on Your Royalties — Here's How

There's a very specific kind of panic post that shows up in author groups every few months: someone had a great year, royalties jumped, and then the tax bill landed and it was brutal. Usually followed by "I have an accountant, but is there something I'm missing?"

Here's the honest answer: probably, yes — not because your accountant is bad, but because a lot of legitimate tax-reduction tools are opt-in. Nobody applies them automatically on your behalf; you have to know they exist and ask for them. So here's the real list, sorted by what actually works and where.

One thing up front: everything below is a legal, ordinary part of the tax system in each country — not a loophole, not aggressive planning, just tools that exist and go unused because nobody mentioned them. This is general education, not personalized advice for your specific numbers — take it to an accountant in your country before you act on it.

Pay the tax man - just don't leave a tip!

Before anything clever, the biggest lever most authors leave on the table is simply under-claiming ordinary business expenses. If it's spent to produce or sell your books, it's almost certainly deductible against your royalty income, wherever you are:

• Editing, proofreading, cover design, formatting

• Advertising (Facebook/Amazon/BookBub ads, ARC services, promo sites)

• Software and subscriptions (writing software, Klaviyo/mailing list tools, Canva, stock photos, Shopify/BookFunnel fees)

• Website and domain costs

• Courses, conferences, and professional memberships (yes, including this one)

• A portion of your home office, internet, and phone

• Equipment (laptop, microphone for audiobooks, external hard drives)

• Bank and payment processing fees on your business account

The reason this matters more than people think: every dollar of legitimate expense reduces your taxable royalty income before any of the country-specific tools below even come into play. If you're not running these through a dedicated business account with real bookkeeping, you're almost certainly missing some of them.

United States

Retirement contributions are your biggest lever. A SEP IRA or Solo 401(k) lets you shelter a serious chunk of royalty income before tax. For 2026, a Solo 401(k) allows an employee deferral of up to $24,500 plus an employer contribution of up to 25% of compensation, for a combined cap of $72,000 (more if you're 50+, thanks to catch-up contributions). A SEP IRA caps out at the same $72,000 figure, calculated as roughly 20% of your net self-employment income after adjusting for self-employment tax — simpler to administer, slightly less flexible than a Solo 401(k). Either one is a direct, dollar-for-dollar reduction in taxable income, not just a "someday" retirement gesture.

Self-employed health insurance deduction. If you're paying your own health insurance premiums (common for full-time indie authors), those premiums are deductible above the line — a genuinely underused deduction for people who left a day job with employer coverage.

The QBI deduction (Section 199A). As a pass-through business (sole prop, LLC, S-corp), you may be able to deduct up to 20% of your qualified business income before tax. This one has income-level phase-outs and nuances your accountant needs to check every year, but it's automatic in the sense that you don't have to "do" anything except make sure it's being claimed.

Home office deduction, done properly (a space used regularly and exclusively for your author business), is a legitimate deduction most people either skip out of fear of an audit or claim incorrectly.

Once profit is solidly six figures, an S-corp election lets you split income into salary + distributions, reducing the portion subject to the 15.3% self-employment tax. (Covered in more depth in an earlier post — it's a structure decision, not a same-year tax hack, so don't rush it.)

Canada

RRSP contributions are the single most direct lever available to a sole proprietor. For 2026, you can contribute up to 18% of your prior year's earned income, to a maximum of $33,810 (plus any unused room carried forward from previous years) — and every dollar contributed comes straight off your taxable income for the year. If you had a huge royalty year, this is the first thing to check before your accountant files.

Capital cost allowance (CCA) lets you depreciate equipment — your laptop, microphone, office furniture — against income over time, rather than just claiming the year-of-purchase cost.

Home workspace expenses (a reasonable proportion of rent/mortgage interest, utilities, and home insurance based on the percentage of your home used for the business) are fully deductible for a sole proprietor working from home, which is most authors.

Once your royalty income comfortably exceeds what you need to live on, incorporating lets you pay the (much lower) small business corporate tax rate on income you leave inside the company to reinvest or grow, rather than your full personal marginal rate — you're only taxed personally when you actually pull the money out. This is a genuine deferral strategy, but it only pays off once there's real surplus income to defer, and the incorporation/accounting costs need to be worth it.

Spousal RRSP contributions are worth a conversation with your accountant if there's a significant income gap between you and a spouse — it's a legitimate, CRA-sanctioned income-splitting tool in retirement, unlike a lot of income-splitting ideas that get flagged by the newer TOSI (tax on split income) rules.

United Kingdom

Pension contributions are the headline lever. For every £80 you personally pay into a pension, HMRC adds £20 automatically (basic-rate relief at source) — turning it into a £100 gross contribution. If you're a higher-rate taxpayer, you claim the additional relief through your Self Assessment return, which doesn't happen automatically — you have to declare the gross contribution amount yourself. The annual allowance for 2026/27 is £60,000 (or 100% of your relevant UK earnings, if lower), so a big royalty year is exactly the moment to check whether you're using this fully — including any unused allowance carried forward from the previous three tax years.

Claim every allowable business expense (see the universal list above) rather than the flat £1,000 trading allowance — once your real expenses exceed £1,000, itemizing wins every time.

Gift Aid. If you're a higher or additional-rate taxpayer and give to charity, Gift Aid donations extend your basic-rate tax band, effectively giving you extra relief on the donation beyond what the charity itself receives — a genuinely underused lever after a high-income year.

Once profits are consistently outpacing your living costs, moving to a limited company and paying yourself a mix of salary and dividends (rather than taking everything as sole-trader profit taxed at your full marginal rate) becomes worth running the numbers on — this is the UK equivalent of the US S-corp / Canada incorporation conversation, and again, it's a structural decision, not a quick fix for one big year.

Australia

Income averaging for special professionals — this is the one authors specifically should know about and often don't. The ATO has a dedicated averaging scheme for "special professionals," and authors are explicitly included in the definition (alongside performers, inventors, and other creatives with copyright income), as long as you've earned more than $2,500 in professional income in the current or an earlier year. The mechanism: your current year's professional income is compared against your average taxable professional income over the preceding four years, and only the amount above that average gets the special treatment — spread across a five-step calculation that effectively taxes the spike at something closer to your average rate rather than your marginal rate for that one big year. This exists precisely for the "huge launch, huge tax bill" scenario, and it's genuinely underused because most general accountants don't think to check for it unless you ask.

Concessional super contributions are the other major lever — the cap for 2026-27 is $32,500, and personal contributions you claim as a tax deduction reduce your taxable income directly (note: contributions above your regular employer-style super get taxed at 15% inside the fund rather than your marginal rate, which is the whole point).

Instant asset write-off / depreciation on equipment purchases (laptop, audio gear, office setup) reduces taxable income in the year of purchase or over time, depending on current thresholds — worth checking with your accountant each financial year since these rules shift.

Prepaying deductible expenses before June 30 (ads, subscriptions, editing booked in advance) is a classic, entirely legitimate way to bring a deduction into the current financial year if you're having a big one.

The bottom line

None of this is about being aggressive with the tax office — it's about not leaving money on the table because nobody told you these tools existed. The retirement-contribution options in every country do double duty: they reduce this year's tax bill and build your actual retirement, which as a self-employed author is entirely on you to sort out. And the Australian income-averaging rule in particular is the kind of thing that exists specifically for people like you — a spiky, unpredictable, royalty-driven income — and sits unused because it's buried in ATO paperwork nobody reads for fun.

If you had a big tax surprise this year: don't just ask "what did I miss," bring your accountant this specific list and ask which of these apply to you before next year's bill lands.

Jo and Jodi's takeaway: If you are not sure, take 30% or your earnings and put them in a separate account as you go. Then, when it comes to tax time, you have the money ready to pay it without the panic. If you've done a great job in deducting your expenses you may even end up with a little left over in your account.

The numbers above can change, so it's always worth checking with your accountant before filing your taxes. When choosing an accountant, find one who is used to working with authors or with self employed people. They may even have some ideas we've missed from this list!
