Building your career as an author—whether self-published, hybrid, or traditionally published with side income—is thrilling. But there’s one crucial part of the business that too many creatives overlook: taxes. We get it—“estimated quarterly payments” aren’t exactly inspiring. But understanding your financial responsibilities as an author in 2025 will save you from IRS nightmares and help you run your writing life like the business it is.
At Midnight Editors, we’re not CPAs, but we are pros at helping authors thrive—and that includes making sure your career has a solid, sustainable foundation. Whether you’ve sold 500 books or 50,000, here’s what you need to know about filing taxes as a working author in 2025.
You Are a Business—Even If You’re Just Starting Out
The IRS still classifies self-published writers as sole proprietors or self-employed individuals. That means your book income—whether it’s from Amazon KDP, Etsy, Substack, Patreon, speaking gigs, or freelance writing—must be reported on your Schedule C as part of your personal tax return.
Even if you’re also employed full-time elsewhere, your author income is still taxable, and the IRS expects you to treat it like a small business. And yes, that means you’ll likely owe self-employment tax in addition to federal and state income tax.
What’s a Schedule C (and Do You Really Need It)?
Short answer: Yes. IRS Form Schedule C is where you report your business income and expenses as a sole proprietor.
Here’s a breakdown:
- Part I: Gross income from all sources—book sales, royalties, speaking fees, courses, coaching, Patreon, etc.
- Part II: Your deductible business expenses (see below!).
- Parts III–V: Used if you carry inventory, drive for business purposes, or have additional info not captured above.
If you net more than $400/year from your writing-related work, the IRS considers that taxable self-employment income.
Common Author Deductions in 2025
Here’s where it gets fun. You can absolutely deduct legitimate expenses that support your author business. In fact, it’s a smart strategy to reduce your taxable income while building your brand. Just remember: your deductions must be ordinary and necessary per IRS rules.
Here’s what authors are deducting in 2025:
✅ Professional Services:
Editing, book coaching, ghostwriting, cover design, formatting, website development, AI assistants like ChatGPT Pro (yes, software counts!).
✅ Tech & Subscriptions:
Scrivener, Canva Pro, Zoom Pro, Jasper, Grammarly, AI transcription services, Substack Pro, newsletter tools like ConvertKit, and your domain/hosting fees.
✅ Marketing Costs:
Book launch ads (Amazon, Facebook, TikTok), newsletter swaps, promo sites, ARCs, PR consultants, and swag.
✅ Research & Books:
Any books, films, or subscriptions (hello, Criterion Channel and MasterClass) used for novel research or education.
✅ Home Office:
If you have a dedicated writing space in your home, you can deduct a portion of rent, utilities, and internet.
✅ Office Supplies:
Printers, ink, notebooks, pens, lighting, ergonomic chairs, whiteboards—if you use it to write, it’s likely deductible.
✅ Travel & Conferences:
Registration fees, airfare, lodging, and mileage to writer events or for research. (Meals are still only 50% deductible unless part of a business meeting.)
✅ Coaching & Education:
Online courses, mentorships, editorial feedback, and writing retreats—if they help your writing biz grow, they qualify.
✅ eBook & Audiobook Production:
ACX fees, narrator payments, translation costs, or AI tools used to generate or enhance audio/eBooks.
New in 2025: What’s Changed?
Digital Assets + NFTs: If you sold or minted digital content like limited-edition eBooks or NFTs, the IRS now treats these as capital gains in some cases. You may need to report proceeds separately. Track them carefully.
AI Revenue Streams: Income from licensing your writing voice to AI platforms or collaborating with synthetic narrators is taxable—and should be reported just like royalties.
Social Media Monetization: If you earn from platforms like TikTok Creator Fund, YouTube Ads, or Instagram Reels bonuses, you must include that income on your return.
Cash App Reporting Thresholds Lowered: Payment platforms like Venmo, PayPal, and Zelle are now required to issue 1099-K forms if you receive more than $600/year for business transactions—down from $20,000 a few years ago.
Pro Tips for Authors Managing Taxes in 2025
Track Everything: Use tools like QuickBooks Self-Employed, Wave, or even Notion templates to track your income and expenses throughout the year.
Pay Quarterly: If you expect to owe over $1,000 in taxes this year, you’re required to make quarterly estimated tax payments (due April, June, September, and January).
Separate Bank Accounts: Keep your book biz separate from your personal life. Open a dedicated checking account for royalties, expenses, and tax savings.
Hire a Pro: Especially if you’re making over $10K/year in author income or navigating multiple revenue streams, a tax professional who understands creative freelancers is worth every penny.
Final Word
Being an author in 2025 means being a business owner, marketer, and yes—even a part-time bookkeeper. But don’t let the word “taxes” scare you away from pursuing your dream. When managed properly, your writing income can fund your future, fuel your creative freedom, and open up new opportunities year after year.
