What You Can Deduct as a 1099 Contractor

You can deduct business expenses that reduce your taxable income, but only costs directly tied to earning your 1099 income

As a 1099 contractor, you report income on Schedule C (Profit or Loss from Business), and that form lets you subtract business expenses from your gross income. The IRS allows deductions for ordinary and necessary expenses — meaning costs that are standard in your line of work and genuinely required to do the job. The key rule: the expense must be for your business, not personal use, and you must have records to back it up.

The difference between a 1099 contractor and a W-2 employee matters here. Employees can only deduct certain unreimbursed work expenses on Schedule A (if they itemize), and those are capped. Contractors deduct on Schedule C, which means the deductions reduce your self-employment tax as well as income tax — a bigger benefit. But the IRS watches 1099 deductions closely, especially if your expenses are high relative to your income.

Key Takeaways

• Home office, vehicle mileage, equipment, software, and professional services are commonly deductible if they are used only for your business.
• You must keep receipts, invoices, mileage logs, or other records for every deduction you claim, because the IRS can ask for proof.
• Personal expenses — groceries, rent, utilities for your whole home — are never deductible, even if you work from home.
• If you use something for both business and personal reasons, you can only deduct the business percentage, and you must track that split.
• Meals, entertainment, and vehicle expenses have special rules about what portion you can deduct and what records you need.

Home office deduction: the two methods and what each covers

If you have a dedicated space in your home used only for work, you can deduct home office expenses. The IRS offers two ways to calculate this: the simplified method and the regular method.

The simplified method lets you deduct $5 per square foot of dedicated office space, up to 300 square feet (so a maximum of $1,500 per year). You do not need to track utilities or repairs — you just measure the room and multiply. This method is fast and requires minimal record-keeping.

The regular method requires you to calculate the percentage of your home used for business, then deduct that same percentage of your mortgage interest (or rent), property taxes, utilities, insurance, repairs, and depreciation. If your office is 200 square feet and your home is 2,000 square feet, you deduct 10 percent of those costs. This method yields a larger deduction in most cases but demands detailed records and is more complex at tax time. You report it on Form 8829 (Expenses for Business Use of Your Home).

Vehicle and mileage deductions: tracking requirements and the standard rate

If you drive for business — client meetings, job sites, supply runs — you can deduct those miles. You have two options: the standard mileage rate or the actual expense method.

The standard mileage rate is simpler. You multiply your business miles by the IRS rate for that year (the rate changes annually and varies by vehicle type). You must track the date, destination, business purpose, and number of miles for each trip. A mileage log or app that records GPS data works. Commuting from home to your regular workplace does not count, but a trip to meet a client, pick up supplies, or visit a job site does.

The actual expense method means you deduct a percentage of your total vehicle costs: gas, maintenance, insurance, registration, depreciation, and repairs. You calculate the percentage by dividing business miles by total miles driven that year. This method requires receipts for every expense and a detailed mileage log. It often yields a higher deduction if you drive a lot for business, but it is more work to track.

You cannot switch between methods every year without IRS permission, so choose carefully in year one. If you use the standard rate in year one, you can switch to actual expenses later, but going the other direction is harder.

Equipment, software, and tools: what counts and depreciation rules

Equipment and tools you buy for your business are deductible, but the timing depends on the cost. Items under $2,500 can usually be deducted in full in the year you buy them (this threshold changes, so check current rules). Expensive items — a computer, camera, vehicle, or machinery — must be depreciated, meaning you deduct a portion each year over several years.

Software subscriptions (design tools, accounting software, project management platforms) are fully deductible in the year you pay for them. Office furniture, a desk, filing cabinets, and shelving are deductible. A laptop or camera used only for work is deductible. A phone or internet bill is deductible only for the business percentage — if you use your phone 80 percent for work and 20 percent personal, you deduct 80 percent of the bill.

Keep the receipt and note the purchase date and business purpose. For items over $2,500, you will need to file Form 4562 (Depreciation and Amortization) with your tax return to claim the deduction.

Meals, entertainment, and travel: the 50 percent rule and documentation

Meals and entertainment have a special rule: you can deduct only 50 percent of the cost (this was temporarily 100 percent for certain meals in 2021 and 2022, but has returned to 50 percent). The meal or entertainment must be directly related to your business — a client lunch, a working meal during a business trip, or a meal with a colleague to discuss a project.

You must keep a receipt showing the date, location, amount, and attendees. Write down the business purpose on the receipt or in a log. A receipt that just says "Restaurant XYZ $45" is not enough; you need to note who you met and why.

Travel expenses — hotel, airfare, rental car, parking — are fully deductible if the trip is for business. If you combine business and personal travel (a conference in another city, plus a weekend vacation), you can deduct only the business portion. Airfare to the destination is deductible if the primary purpose is business; hotel and meals during the business days are deductible; personal days are not.

Professional services and subcontractors: when you can deduct payments to others

If you pay another contractor or professional to do work for your business, that payment is deductible. Examples include hiring a bookkeeper, paying a designer to create a logo, hiring a photographer for a shoot, or subcontracting part of a project to another contractor. You deduct the full amount you paid.

You must issue a Form 1099-NEC to anyone you paid more than $600 in a year (the threshold may vary by state). Keep invoices and records of what work was done. If you pay a business (not an individual) for services — a marketing agency, a software developer's company — you typically do not issue a 1099, but you still deduct the cost.

Payments to employees are handled differently: you withhold taxes and issue a W-2, not a 1099. If you are unsure whether someone is an employee or a contractor, the IRS has rules about control, payment terms, and relationship that determine the classification.

Insurance, licenses, and professional development: ongoing business costs

Business insurance — liability, professional liability, or workers' compensation — is fully deductible. Health insurance premiums you pay as a self-employed person are also deductible (on Form 1040, not Schedule C, but they reduce your taxable income).

Professional licenses, certifications, and memberships are deductible if they are required or improve your skills in your current line of work. A plumber's license renewal, a real estate agent's continuing education, or a professional association membership all count. A degree or certification that qualifies you for a new career does not.

Training, courses, and conferences related to your business are deductible. Books, subscriptions to industry publications, and online courses are deductible. Travel to a conference is deductible (using the travel rules above). Personal development that is not directly tied to your current business is not deductible.

What you cannot deduct: personal expenses and common mistakes

Personal expenses are never deductible, even if you work from home. Groceries, personal clothing, haircuts, gym memberships, and entertainment for yourself are personal. Rent or mortgage for your whole home is personal (only the home office percentage is deductible). Utilities for your whole home are personal (only your home office percentage counts).

Commuting expenses — gas to drive to a regular workplace, parking at an office, public transit to a job site — are not deductible. The IRS considers commuting a personal expense. However, if you drive from one client site to another during the workday, that is deductible.

Fines and penalties are not deductible. Traffic tickets, parking violations, and late fees are personal. Clothing is deductible only if it is specialized work gear (a chef's uniform, a construction hard hat, safety boots) that you would not wear otherwise; regular clothes are not deductible even if you wear them to work.

A common mistake is deducting a portion of rent or utilities without a dedicated home office. The IRS requires a specific space used regularly and exclusively for business. A corner of your bedroom or a desk in your living room does not may have access to. Another mistake is mixing personal and business use without tracking the split — if you use a vehicle 30 percent for business and 70 percent personal, you can only deduct 30 percent of costs, and you must prove that split with a mileage log.

Record-keeping: what to save and how long to keep it

The IRS can audit a 1099 contractor's return up to three years after filing (or longer if there are errors). Keep receipts, invoices, bank statements, credit card statements, mileage logs, and any other proof of expenses for at least three years. Digital copies are acceptable if they are clear and complete.

For mileage, a log with the date, destination, business purpose, and miles is essential. Apps like Stride Health or MileIQ can automate this. For meals and entertainment, keep the receipt and note the attendees and business purpose. For home office, keep records of your home's square footage and the office space square footage, plus receipts for any repairs or improvements.

Organize by category — vehicle, meals, equipment, software, travel — so you can find records quickly if asked. A spreadsheet or accounting software like QuickBooks Self-Employed can help you track and categorize expenses throughout the year, making tax time easier.

Frequently Asked Questions

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

Yes, but only the business percentage. If you use your internet 80 percent for work and 20 percent personal, you deduct 80 percent of the bill. You must be able to estimate or justify that split. If you have a separate business internet line, you can deduct 100 percent of that line's cost.

What if I use my car for both business and personal driving?

You can only deduct the business percentage. If you drove 12,000 miles total and 3,000 were for business, you deduct 25 percent of your vehicle costs (or 25 percent of the standard mileage rate times 3,000 miles). A mileage log is the best proof of this split.

Do I have to deduct everything, or can I skip some expenses?

You do not have to deduct every expense, but it is usually in your interest to do so. Deductions reduce your taxable income and your self-employment tax. The only reason to skip a deduction is if it creates a loss that you cannot use or if it triggers an audit risk you want to avoid, but that is rare.

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

The IRS can disallow the deduction if you cannot produce proof. For small expenses under $75, you can use a credit card statement or bank record instead of a receipt in some cases, but a receipt is always safer. If audited and you lack documentation, you lose the deduction and may owe penalties and interest.

Can I deduct a home office if I also work at a client's office?

Yes, if you have a dedicated home office used regularly for business. Many contractors work at multiple locations — client sites, coffee shops, home — and still deduct a home office where they do administrative work, invoicing, or planning. The office must be used exclusively for business, not shared with personal activities.
