Categorizing Author Tax Deductions: What You Can Legally Write Off

One of the biggest mistakes authors make is paying more tax than necessary simply because they don't understand which business expenses are deductible.

If you're earning income as an author, the tax authorities generally allow you to deduct reasonable expenses incurred to earn that income. In other words, if the expense helps you write, publish, market, or sell your books, it may qualify as a business expense.

Keeping accurate records throughout the year can save thousands of dollars at tax time.

Disclaimer: Tax laws vary by country and individual circumstances. Always consult a qualified accountant or tax professional regarding your specific situation.

Software & Subscriptions

Many of the tools authors use every day are legitimate business expenses.

Examples include:

• Writing software (Scrivener, Atticus, Vellum)

• Editing tools (ProWritingAid, Grammarly)

• Design software (Photoshop, Canva)

• Email marketing platforms (Klaviyo, MailerLite, ConvertKit)

• Website hosting and domain registration

• Project management software

• Cloud storage subscriptions

If the software is used primarily for your author business, it is often deductible.

Professional Services

The people you hire to help produce and market your books are typically deductible business expenses.

Examples include:

• Editors

• Proofreaders

• Cover designers

• Formatters

• Virtual assistants

• Advertising consultants

• Accountants and bookkeepers

• Website developers

Keep invoices and receipts for all contracted services.

ARC Copies & Review Expenses

Advanced Reader Copies (ARCs) are a marketing expense.

You may be able to deduct:

• Printed ARC copies

• Shipping costs

• Packaging materials

• Promotional bookmarks and inserts

• Review copy giveaways

These expenses are incurred specifically to generate reviews and book awareness.

Advertising & Marketing

Marketing is one of the most common author deductions.

Examples include:

• Facebook ads

• Amazon ads

• BookBub promotions

• Newsletter swaps

• Giveaway costs

• Book fair fees

• Conference sponsorships

• Promotional graphics and videos

Maintaining records of ad spend throughout the year is essential.

Research Expenses

Research directly related to your books may be deductible.

Examples include:

• Books purchased for research

• Historical archives

• Museum admission fees

• Research databases

• Expert consultations

• Language resources

The expense should have a clear connection to your writing business.

Research Trips & Travel

Travel can become deductible when it is primarily for business purposes.

Examples may include:

• Visiting a book setting for research

• Attending writing conferences

• Author conventions

• Industry networking events

• Educational workshops

Keep documentation showing the business purpose of the trip.

Travel expenses can include:

• Transportation

• Accommodation

• Registration fees

• Business-related meals (subject to local tax rules)

Personal vacation expenses generally cannot be claimed as business deductions.

Home Office Expenses

If you regularly work from home, you may qualify for a home office deduction.

Potential deductions can include:

• A percentage of rent or mortgage interest

• Property taxes (where permitted)

• Utilities

• Internet

• Home insurance

• Maintenance costs

The workspace typically needs to be used regularly and primarily for business activities.

Many full-time authors overlook this valuable deduction.

Equipment & Technology

Authors often invest heavily in technology.

Potential deductible purchases include:

• Computers

• Monitors

• Printers

• Cameras

• Microphones

• Audiobook recording equipment

• Tablets and e-readers used for business

Depending on local tax regulations, these purchases may be deducted immediately or depreciated over time.

Books, Courses & Education

Investing in your professional development can often qualify as a business expense.

Examples include:

• Writing courses

• Marketing courses

• Publishing workshops

• Industry conferences

• Business coaching

• Educational books

The education should relate directly to improving or maintaining your author business.

The Importance of Record Keeping

A deduction is only valuable if you can support it.

Best practices include:

• Saving all receipts

• Using a dedicated business bank account

• Tracking expenses monthly

• Maintaining digital copies of invoices

• Recording the business purpose of major purchases

Good records make tax season faster, easier, and far less stressful.

The Bottom Line

Every dollar you legally deduct reduces your taxable profit.

Most successful authors don't just focus on increasing revenue—they also focus on understanding their expenses, tracking their deductions, and keeping more of what they earn.

The goal isn't to avoid taxes.

The goal is to pay only the taxes you actually owe.
