What Business Expenses You Can Deduct on a 1099

Business expenses reduce your taxable income when you file a 1099

When you receive a 1099, you report the income on your tax return, but you also get to subtract business expenses — the costs you paid to earn that income. The IRS calls this a deduction. The money you spend on supplies, equipment, or services that directly help you do the work counts. What you cannot deduct are personal expenses, things you would buy anyway, or costs that benefit you outside of work.

The key rule is this: the expense must be both ordinary (common in your line of work) and necessary (helpful to doing the job). A plumber can deduct a wrench. A freelance writer can deduct software. A consultant cannot deduct a vacation, even if they think about work while there.

You do not need to itemize or use a special form to claim deductions — you report them on Schedule C (Form 1040), which is where 1099 income goes. The more legitimate expenses you can document, the lower your taxable income becomes.

Key Takeaways

• You can deduct supplies, equipment, software, and tools you buy specifically for the work the 1099 reports.
• Home office expenses — a portion of rent, utilities, and internet — are deductible if you use a dedicated space only for work.
• Vehicle expenses count only for business miles, not commuting, and you must track mileage or keep receipts for gas and repairs.
• Professional services like accounting, legal information, and contractor fees are deductible if they relate directly to earning the 1099 income.
• You must keep receipts and records for every deduction; the IRS can ask you to prove an expense was real and business-related.

Supplies, equipment, and tools you buy for the work

Anything you purchase specifically to do the job — and that wears out or gets used up — is deductible. This includes office supplies (paper, pens, ink cartridges), software subscriptions (design tools, accounting software, project management apps), and small tools or equipment under a certain cost threshold.

The IRS sets a dollar limit for what counts as a small tool versus a capital asset. Generally, if something costs less than $2,500 and lasts less than a year, you can deduct it in full in the year you buy it. If it costs more or lasts longer — like a computer or camera — you may need to depreciate it over several years instead of deducting the whole cost at once. Your tax software or accountant can walk you through which category an item falls into.

Keep the receipt or invoice showing what you bought, when, and how much you paid. If you buy supplies in bulk, you can deduct them in the year you purchase them, even if you use them over multiple years.

Home office expenses

If you work from home and use a dedicated space only for work, you can deduct a portion of your rent or mortgage interest, utilities, internet, and home insurance. You cannot deduct the whole amount — only the percentage that matches the square footage of your office compared to your whole home.

For example, if your office is 200 square feet and your home is 2,000 square feet, your office is 10 percent of your home. You can deduct 10 percent of your rent, electric bill, internet, and similar expenses. You can also deduct 100 percent of expenses that are only for the office, like a desk lamp or office paint.

The IRS offers two methods: the regular method (calculate the percentage and deduct that share of actual expenses) and the simplified method (deduct $5 per square foot of office space, up to 300 square feet, for a maximum of $1,500 per year). The simplified method is easier if you do not want to track every utility bill. Keep receipts for whichever method you choose.

Vehicle and mileage expenses

If you use your car for work — driving to client meetings, job sites, or to pick up supplies — you can deduct those miles. You cannot deduct commuting to and from your regular workplace, but you can deduct miles driven for business purposes during the workday.

You have two options: track your actual mileage and use the IRS standard mileage rate (which changes each year), or keep receipts for gas, repairs, insurance, and maintenance and deduct a percentage based on how much of your driving is for work. The mileage method is simpler for most people. Write down the date, destination, purpose, and miles driven for each trip, or use a mileage-tracking app.

If you own the vehicle outright, you can also deduct depreciation. If you financed it, you can deduct interest on the loan (but not the principal payment). Your accountant can help you decide which method saves you more money.

Professional services and contractor fees

You can deduct fees you pay to accountants, lawyers, bookkeepers, and other professionals who help you run your business or understand your taxes. You can also deduct payments to other contractors or freelancers if you hire them to do work related to your 1099 income — for example, hiring a designer to create a logo for your consulting business, or paying a virtual assistant to manage your schedule.

Keep invoices from these professionals showing what service they provided and when. If you pay a contractor more than $600 in a year, you will need to issue them a 1099-NEC form, so track those payments carefully.

Meals, travel, and client entertainment

Meals and entertainment are only partially deductible. As of 2024, you can deduct 50 percent of meal expenses if they are directly related to your business — for example, a meal with a client to discuss a project. You cannot deduct meals you eat alone while working, even if you work through lunch.

Travel expenses for business trips are deductible: airfare, hotel, rental car, and meals while traveling. The trip must be primarily for business, not pleasure. If you combine business and vacation, you can only deduct the business portion. Keep receipts for flights, hotels, and rental cars. For meals during travel, the 50 percent rule still applies.

Client entertainment — tickets to a game or show, for example — is also 50 percent deductible if it is directly tied to your business relationship. Gifts to clients are deductible up to $25 per person per year.

Insurance, licenses, and professional memberships

Business liability insurance, professional liability insurance, and health insurance premiums you pay as a self-employed person are deductible. If you are a sole proprietor, you can also deduct a portion of your self-employment tax on your income tax return.

Professional licenses, certifications, and renewal fees are deductible. Membership dues to professional organizations related to your field are deductible. Continuing education courses that help you stay current in your profession are deductible, including tuition, books, and materials.

Keep receipts for all of these. If you renew a license every two years, you can deduct it in the year you pay for it.

What you cannot deduct

Personal expenses are never deductible, even if you use them while working. Clothing is not deductible unless it is a uniform or protective gear required for the job (a chef's coat, safety glasses, a hard hat). Gym memberships, haircuts, and grooming are personal. A home office in a shared space where you also watch television or sleep is not deductible.

Commuting to your main workplace is not deductible. Fines and penalties are not deductible. Expenses for hobbies or side projects that do not generate income are not deductible. Gifts over $25 per person per year are not deductible. Alcohol is not deductible (though meals that include alcohol are 50 percent deductible if the meal itself is business-related).

If you are unsure whether an expense qualifies, ask yourself: would I buy this if I did not have this 1099 income? If the answer is yes, it is probably personal, not business.

Frequently Asked Questions

Do I need receipts for every deduction?

Yes. The IRS can ask you to prove any deduction, and a receipt is your proof. For expenses under $75, you can use a credit card statement or bank record instead of a receipt in some cases, but a receipt is safer. Keep receipts for at least three years after you file your return.

Can I deduct a computer or phone I use for work?

Yes, but how depends on the cost and how long it lasts. A computer or phone under $2,500 that you use only for work can usually be deducted in full in the year you buy it. If it costs more, you depreciate it over several years. If you use it for both work and personal use, you can only deduct the work percentage.

What if I work from a coffee shop instead of home?

You cannot deduct the coffee shop rent or your coffee. You can deduct internet if you pay for a dedicated business plan, but not the cost of sitting there. If you rent a dedicated office or coworking space, that rent is fully deductible.

Can I deduct my internet bill if I work from home?

Only the business percentage. If you use your home internet 50 percent for work and 50 percent for personal use, you can deduct 50 percent of the bill. If you pay for a separate business internet line, you can deduct 100 percent of that line.

What happens if I claim a deduction and do not have a receipt?

If the IRS audits you and asks for proof, you cannot claim the deduction without documentation. The IRS may disallow it and charge you back taxes plus interest. It is not worth the risk — keep receipts for everything.
