Just because you’re an author doesn’t mean everything is deductible.

One of the fastest ways authors get themselves into trouble is by assuming that anything vaguely related to writing must be deductible. Bought a new laptop? Deductible. Subscribed to five streaming services “for research”? Maybe not. Took a vacation where you thought about your book once? Definitely not.

Understanding what you can deduct—and what you shouldn’t—isn’t about being stingy or paranoid. It’s about running a legitimate business, keeping clean records, and avoiding problems that can snowball later.

The golden rule of deductions: ordinary and necessary

The IRS uses two deceptively simple words to define business expenses: ordinary and necessary. Ordinary means common and accepted in your field. Necessary means helpful and appropriate for running your business.

Notice what’s missing: fun, convenient, or ‘I really wanted it.’ If an expense doesn’t clearly support your author business, it doesn’t belong on your tax return.

Expenses that are usually deductible for authors

These are the expenses that typically pass the ordinary-and-necessary test for indie authors and publishing professionals.

Production costs

Editing, proofreading, cover design, interior layout, ISBNs, illustrations, maps, proof copies, and formatting tools all directly support producing a book. These are core business expenses.

Marketing and promotion

Ads, newsletter promos, ARC services, blog tours, social media graphics, email platforms, and review services generally qualify because they’re tied to selling and promoting your work.

Software, tools, and subscriptions

Writing software, design tools, accounting platforms, cloud storage, font licenses, and stock image subscriptions are deductible if they’re used for your author business.

Professional services

Editors, designers, accountants, lawyers, consultants, and virtual assistants aren’t luxuries—they’re part of running a business. Their fees are legitimate deductions.

Education and industry development

Courses, conferences, workshops, and memberships are deductible when they improve your existing skills or help you operate your author business more effectively.

Expenses that are sometimes deductible (with conditions)

These expenses live in the gray area. They may be deductible, but only if you meet specific criteria and keep good documentation.

Home office expenses

If you qualify for a home office deduction, a portion of utilities, internet, rent, or mortgage interest may be deductible. If the space isn’t used regularly and exclusively for business, it doesn’t qualify.

Travel and meals

Travel for book signings, conferences, or publishing events can be deductible. Meals may be partially deductible when they’re clearly tied to business. Personal travel with a ‘business excuse’ does not count.

Equipment

Computers, monitors, cameras, and other equipment may be deductible or depreciated if they’re used primarily for your author business. Mixed personal use complicates things.

Expenses that usually are NOT deductible

This is where authors often get tripped up—not out of malice, but optimism.

Personal living expenses

Groceries, rent, utilities, clothing, and personal entertainment aren’t deductible just because you write at home or read books for inspiration.

Hobbies and unrelated purchases

Craft supplies, random online courses, or software unrelated to publishing don’t become deductible simply because you’re an author.

Commuting costs

Driving to your regular coffee shop or writing space is considered commuting, not business travel—even if that’s where you do your best work.

Why mixing personal and business expenses causes problems

When personal and business expenses blur together, your records become unreliable. That makes it harder to defend deductions, harder to see true profitability, and harder to work with a tax professional.

Clear separation protects you. It also saves time and stress when tax season arrives.

How to stay on the safe side (without paranoia)

You don’t need to audit yourself. You do need consistency and documentation. Track expenses as they happen, keep receipts or invoices, and categorize thoughtfully.

When in doubt, ask a CPA—or don’t deduct it. Paying a little more tax is far less painful than paying penalties later.

Let’s Be Honest: deductions should support your business, not stretch the truth

Deductions are there to recognize the real costs of running a business—not to justify personal spending. When you understand the difference, you protect your money, your credibility, and your long-term author career.
