Can I Deduct Expenses for Writing a Book?

You can deduct the expenses of writing a book on your federal tax return if the IRS treats your writing as a business rather than a hobby. Once that threshold is cleared, ordinary and necessary costs of researching, producing, and promoting the book come off your book income on Schedule C, and you pay tax only on the net profit. If your writing is classified as a hobby, none of those expenses are deductible.

The Business-or-Hobby Gate

Everything downstream depends on this classification. Writing pursued for profit is a business; writing pursued mainly for personal enjoyment is a hobby. The Tax Cuts and Jobs Act eliminated the deduction for hobby expenses, and the One Big Beautiful Bill Act made that elimination permanent beginning in 2026.¹

The IRS presumes your writing is a business if it turns a profit in at least three of the most recent five tax years.¹ Meeting the test shifts the burden to the IRS to prove otherwise. If you don’t meet it, you can still qualify by showing a genuine profit motive through other evidence:

Businesslike conduct: separate financial records, a business bank account, systematic tracking of income and expenses.
Time and effort devoted regularly to writing, revising, and marketing.
Expertise developed through study, workshops, or work with publishing professionals.
Whether you depend on the income or treat it as recreational.
A history of profit, or losses that shrink as you build an audience.
Active marketing: seeking publishers, pitching agents, promoting self-published titles.

Enjoying the work does not by itself make it a hobby. But no business plan, no marketing, and consistent losses with no sign of a push toward profitability point the other way.

What You Can Deduct

To be deductible, an expense must be ordinary (common and accepted in the writing profession) and necessary (helpful and appropriate for your work). It doesn’t have to be indispensable, only useful for your writing business.² The categories writers most often claim:

Research materials: books, database subscriptions, archive access fees, and museum admission tied to your manuscript topic.
Travel: airfare, hotel stays, and meals (subject to percentage limits) when traveling overnight for research, conferences, or book events.
Vehicle use: mileage for local research trips at the 2026 standard rate of 72.5 cents per mile, or your actual vehicle expenses.
Office supplies: paper, ink, printer cartridges, binding materials, postage.
Equipment and software: laptops, tablets, writing software, reference applications used for your writing business.
Professional services: freelance editors, cover designers, indexers, formatters, literary agents.
Advertising and marketing: website hosting, social media promotion, book launch costs, paid ads.
Education: workshops, conferences, and courses that maintain or improve your existing writing skills. Courses that qualify you for an entirely new profession are not deductible.

Every expense needs a clear connection to your writing business. A laptop used only for writing is fully deductible; one shared with personal use is deductible only for the business portion. Mixed-use items require an honest allocation, and the allocation is what you’ll have to defend if asked.

Deduct Now, Not Later: The Writer’s Exemption

Most businesses that produce physical products must spread production costs over the life of the product under the uniform capitalization rules. Writers get an exemption. Under Section 263A(h), individuals whose personal efforts create a literary manuscript are not required to capitalize their creative expenses, so costs like research, travel, and supplies come off in the year you pay them rather than being spread across future years.³

One boundary matters if you self-publish in print: costs related to printing, photographic plates, video tapes, and similar physical reproduction are excluded from this exemption.³ Printing a run of books is not something you can immediately expense under this provision.

Where the Deductions Go on Your Return

Self-employed writers report both income and expenses on Schedule C (Form 1040). Income means royalties, advances, freelance article payments, and anything else your writing brings in.⁴ Schedule C has designated lines for the common expense categories:⁵

Line 8, Advertising: book promotion, paid social campaigns, marketing materials.
Line 9, Car and truck expenses: mileage or actual expenses for local business driving, such as trips to libraries, archives, or meetings with editors.
Line 11, Contract labor: payments to freelance editors, cover designers, indexers, and other independent contractors.
Line 13, Depreciation and Section 179: equipment like laptops and professional software. Section 179 lets you deduct the full cost of qualifying equipment in the year you buy it rather than depreciating over several years.
Line 18, Office supplies: paper, ink, postage, similar consumables.
Line 24a, Travel: airfare, hotel stays, transportation costs for overnight business trips related to your manuscript.
Line 30, Business use of home: your home office deduction.

Anything without a specific line, such as research database subscriptions or conference registration fees, goes on Line 48 (Part V, Other Expenses) with a description.⁵ Line 31 shows your net profit or loss, which flows to Form 1040. A net loss can offset other income like wages or investment earnings, which is one of the main reasons the business classification matters.

Home Office

If you use part of your home regularly and exclusively for writing, you can claim a home office deduction. The space doesn’t need to be a separate room; any identifiable area works, but it can’t double as personal space.⁶

Regular Method

Calculate the percentage of your home devoted to writing, then apply that percentage to actual home expenses like rent or mortgage interest, utilities, insurance, and repairs. A 200-square-foot office in a 1,600-square-foot home is 12.5% business use, so 12.5% of qualifying household expenses is deductible.⁶

Simplified Method

The simplified method skips the percentage math. You deduct $5 per square foot up to 300 square feet, for a maximum of $1,500 per year.⁷ Recordkeeping is far lighter. If your actual expenses would produce a bigger deduction, the regular method is worth the extra paperwork.

Health Insurance and Retirement Contributions

Two more deductions come with self-employed status and often outweigh the line-item expenses on Schedule C.

If you’re self-employed and not eligible for a health plan through a spouse’s employer, you can deduct 100% of health insurance premiums for yourself, your spouse, and your dependents, including children under age 27 whether or not they are your dependents. The plan must be established under your business, and the deduction goes on Schedule 1 (Form 1040) using Form 7206.⁸ The deduction cannot exceed your net profit from writing for the year.

Self-employed writers can also open tax-advantaged retirement accounts and deduct the contributions. A SEP IRA allows contributions of up to 25% of net self-employment income, with a maximum of $69,000 for 2026.⁹ A solo 401(k) offers similar limits with the added option of employee elective deferrals.

What About Grants, Fellowships, and Advances

Not every dollar a writer receives is a royalty, and the tax treatment shapes what you owe before deductions apply. Book advances are taxable income in the year you receive them and go on Schedule C alongside royalties. If you later return an unearned advance, you can deduct the repayment in the year you pay it back.

Writing grants and fellowships are generally taxable unless you are a degree-seeking student and the money goes to qualified education expenses like tuition and required fees. A fellowship that requires you to produce a manuscript, deliver lectures, or perform research in exchange for the award is treated as payment for services and is fully taxable regardless of student status.¹⁰ Fulbright grants follow the same rule: the portion used for qualified education expenses may be excludable, and any remaining amount is taxable income.

Records That Protect the Deductions

Deductions survive an audit only if you can substantiate them. At a minimum, keep:

Receipts, digital or paper, for every business purchase.
A contemporaneous mileage log showing date, destination, business purpose, and miles driven.¹¹
Income records: 1099 forms, royalty statements, direct sales records.
A dedicated bank account for writing income and expenses, which isolates business transactions cleanly.
Home office measurements if you use the regular method.

Keep tax records for at least three years from the date you file or the due date, whichever is later. If you file a claim for a loss from worthless securities or a bad debt deduction, retention extends to seven years.¹² Copies of the returns themselves are worth keeping indefinitely.
