Tax Basics for Indie Authors: What You Need to Know

Taxes are the part of author business finances most authors prefer not to think about. The combination of self-employment complexity, unfamiliar forms, and the generally unpleasant nature of giving money to the government produces a reliable pattern of avoidance — until the bill arrives and the avoidance has made it significantly larger than it needed to be.

The good news: the tax situation for most indie authors is genuinely more manageable than the anxiety around it suggests. The core concepts aren't complicated, the deductions available are meaningful, and the main requirement is keeping organized records throughout the year rather than scrambling to reconstruct them in April. This article covers the fundamentals every indie author needs to understand — with the consistent caveat that tax law is jurisdiction-specific, changes over time, and your specific situation deserves professional advice rather than reliance on a general overview.

The Two Taxes You Pay on Publishing Income

Most employees are familiar with income tax — the federal, state, and sometimes local tax on earnings. Self-employed people pay income tax too, but they also pay a second tax that employees split with their employers: the self-employment tax, which covers Social Security and Medicare contributions.

⚠ The rates, brackets, and thresholds above reflect US federal tax law as of 2024-2026 and are subject to change. State tax law adds additional variation. Authors in other countries face entirely different tax structures. The numbers here are for orientation, not for tax preparation — consult a tax professional for rates and rules applicable to your specific situation.

Deductible Business Expenses: What You Can Claim

The offset to the self-employment tax burden is that genuine business expenses are deductible — they reduce your net self-employment income, which reduces both income tax and self-employment tax. Most authors claim fewer deductions than they're entitled to, either because they don't know what qualifies or because they haven't kept records.

The key to claiming these deductions is documentation: receipts, bank statements, credit card statements, and a clear business purpose for each expense. The business bank account and expense tracking system from BS09 make this documentation straightforward throughout the year rather than a reconstruction effort at tax time.

Quarterly Estimated Tax Payments

The US tax system is pay-as-you-go — the IRS expects taxes to be paid throughout the year, not in a lump sum at filing time. For employees, this happens automatically through paycheck withholding. For self-employed people, including indie authors, it happens through quarterly estimated tax payments.

The quarterly payment schedule (for US federal taxes) runs roughly as follows:

● Q1 (January 1 - March 31): payment due April 15

● Q2 (April 1 - May 31): payment due June 15

● Q3 (June 1 - August 31): payment due September 15

● Q4 (September 1 - December 31): payment due January 15 of the following year

The amount of each payment should cover at least 90% of your current year tax liability or 100% of the prior year's tax liability (110% if your prior year income exceeded $150,000). Underpayment of estimated taxes results in an underpayment penalty — not dramatic, but avoidable. The tax savings account from BS09 makes these payments straightforward: the money is already set aside.

⚠ Authors who have both W-2 employment income and author business income can sometimes use their W-2 withholding to cover their estimated tax obligations, but this requires careful calculation. Authors whose sole income is publishing are almost certainly required to make quarterly estimated payments once their tax liability exceeds $1,000 for the year. Get clarity on your specific situation from a tax professional before skipping estimated payments.

International Tax Considerations

Authors who publish on international platforms — which includes Amazon's international marketplaces, Apple Books, Kobo, and others — face some additional tax considerations worth understanding.

● W-8BEN form: non-US authors publishing on US platforms need to complete the W-8BEN (for individuals) or W-8BEN-E (for entities) to claim treaty benefits that reduce or eliminate the 30% US withholding tax that would otherwise apply to US-sourced royalty income. US authors may need equivalent forms for non-US platforms.

● Amazon international marketplaces: Amazon collects VAT/GST on ebook sales in markets where it's required (UK, EU, Australia, etc.) and remits it on the author's behalf. The royalty you receive is net of this — you don't separately owe VAT on Amazon sales because Amazon handles it. This is not true for direct sales, as covered in BS09.

● Foreign bank accounts and FBAR: if you maintain a bank account in a foreign country with a balance that exceeds $10,000 at any point during the year, US citizens are required to file an FBAR (FinCEN Form 114) regardless of any tax owed. Most indie authors won't encounter this, but it's worth knowing.

● Authors in non-US countries: the entire tax structure described in this article is US-specific. Authors in the UK, Canada, Australia, and elsewhere have entirely different tax structures, self-employment treatment, and deduction rules. The principles — track income and expenses, understand what you owe, pay on time — are universal; the specifics require a professional familiar with your jurisdiction.

When to Hire a Tax Professional

The question of when to hire an accountant or tax professional is simpler than most authors make it. The answer for most people who are earning meaningful income from a self-employment activity is: as soon as possible, and certainly before their first full year of filing as a self-employed person.

A tax professional who is familiar with self-employment income and creative business deductions will almost always save an author more in correctly claimed deductions than they cost in fees — particularly in the first two or three years when there are structural decisions to be made (business entity, accounting method, depreciation decisions) that have multi-year implications. They also provide the peace of mind that your filing is correct, which has real value in a context where errors have financial and legal consequences.

● Look for a CPA (Certified Public Accountant) or EA (Enrolled Agent) rather than a seasonal tax preparer, particularly if your situation includes an LLC, significant business expenses, or international income

● Look specifically for someone with experience with small business or self-employment income rather than someone whose primary practice is personal returns — the deduction landscape is different enough that general tax preparers sometimes miss legitimate business deductions

● The accountant relationship should be year-round, not just at filing time — your accountant should be available to answer questions about tax implications of specific decisions (LLC formation, S-Corp election, major purchases) before you make them, not just to report them afterward

Conclusion

Tax compliance for indie authors isn't complicated at its core — it requires tracking income and expenses, paying estimated taxes quarterly, claiming the deductions you're entitled to, and filing your return accurately and on time. The complexity lives in the details of your specific situation, which is why the general guidance in this article is the beginning of the conversation rather than the end. A tax professional who understands your business is worth every dollar they cost. The next article moves from the financial and legal infrastructure of your author business to a critical strategic question: when and how to build your backlist as a long-term income asset.
