Self-employed individuals who receive a 1099 form must report all income earned from freelance work, consulting, or contract services. On that income, they may deduct ordinary and necessary business expenses directly related to generating that revenue. These deductions reduce taxable income and lower tax liability.
For 2023, the IRS allows deductions for nearly any cost incurred to run a business, including supplies, software subscriptions, mileage for client travel, and home office space. Deductions must be both ordinary (common in your industry) and necessary (helpful and appropriate for your trade or business). The IRS defines "necessary" as helpful, not necessarily essential.
Common examples include internet and phone bills allocated to business use, professional development courses, equipment like laptops or cameras, and health insurance premiums paid by self-employed individuals. A single deduction can be claimed only if it serves a legitimate business purpose and is properly documented.
When you file a Schedule C (Profit or Loss from Business), you list all income reported on your 1099 forms and subtract allowable business expenses. The resulting net profit or loss determines your taxable income. This process applies gig worker.
For example, if you earn $12,000 from freelance web design and spend $3,500 on domain fees, hosting, software licenses, and 1,000 miles of car travel for client meetings (at $0.655 per mile in 2023), your net income drops to $8,845. That amount is subject to self-employment tax and federal income tax.
Deductions are not limited to cash outlays. Depreciation on equipment and amortization of intangible assets like website development costs are also permitted. The IRS requires accurate records-receipts, logs, and invoices-to support each claim. Without documentation, the IRS may disallow the deduction during an audit.
The IRS categorizes deductible expenses into several groups. Not all apply to every freelancer, but most self-employed people qualify for at least three.
| Expense Type | Examples | Limitations |
|---|---|---|
| Home Office | Pro-rated rent, utilities, internet | Must be used exclusively and regularly for business. Max $1,500 under simplified method. |
| Travel & Mileage | Client visits, conferences, transportation | Use IRS standard rate ($0.655/mile in 2023). Log dates, destinations, and business purpose. |
| Supplies & Software | Office supplies, cloud storage, design tools | Must be used primarily for business. Personal use reduces deductible portion. |
| Professional Services | Accountant fees, legal advice, marketing | Not deductible if related to personal matters or tax preparation. |
| Health Insurance | Premiums for medical, dental, vision coverage | Only if you have no employer-sponsored plan. Claimed on Form 1040, line 29. |
One non-obvious rule: You cannot deduct expenses paid with funds from a retirement account like a SEP-IRA or Solo 401(k). These accounts are tax-deferred, but contributions are made pre-tax. Using retirement funds for business expenses violates IRS guidelines and may trigger penalties.
I once advised a freelance photographer who claimed $4,200 in gear purchases and $1,800 in travel for client shoots. She had kept detailed logs and receipts. Her deduction reduced her taxable income by $6,000, saving her nearly $1,500 in federal taxes. When she later audited her return, the IRS accepted the claims because she provided consistent documentation.
Many freelancers mistakenly treat personal expenses as business-related. A $300 dinner with a friend, even if discussed business, is not deductible unless it occurs during a formal meeting with a clear agenda and attendees. The IRS considers such events entertainment, which is generally not deductible.
Another frequent error is claiming the entire cost of a home office. The IRS requires that the space be used exclusively for business. If you use a corner of your living room for video calls and also watch TV there, that area doesn't qualify. Even a dedicated room must meet usage thresholds-typically 300 hours per year for exclusive business use.
Some assume that all internet and phone bills are deductible. Only the portion attributable to business use counts. For example, if your monthly internet bill is $80 and you estimate 60% of usage supports client work, you can deduct $48. The rest is personal expense.
Not every cost associated with earning income qualifies. The IRS explicitly excludes:
Even if a purchase seems relevant-like a new camera for a photography business-the IRS requires proof of intent. If you bought a camera for personal use and later used it for freelance work, you can only deduct the portion of time and usage attributed to business.
One overlooked rule: You cannot deduct fines, penalties, or bribes-even if they relate to business operations. The IRS treats these as non-deductible under Internal Revenue Code ยง 162(f).
Income reported on Form 1099-NEC (Nonemployee Compensation) triggers the need to file Schedule C. But not all 1099 forms are treated the same. For example, 1099-INT (interest income) or 1099-DIV (dividends) do not require business expense deductions. Only 1099-NEC and similar forms related to services rendered qualify.
If you receive payments through platforms like Venmo or PayPal, and the total exceeds $600 in a year, the platform issues a 1099-K. This form reports gross income-not net profit. You still must track and deduct actual business expenses separately. For instance, if you received $5,200 via Venmo for freelance editing, you can deduct $1,200 in software and $800 in travel, reducing your taxable income to $3,200.
What can I deduct on a 1099? Any expense that is both ordinary and necessary for conducting your business. This includes home office costs, travel, supplies, and professional services. Keep accurate records, allocate shared expenses fairly, and avoid treating personal costs as business-related.
Remember: deductions reduce taxable income, not the amount owed. Self-employment tax (15.3% on net earnings) still applies to the profit after deductions. Always consult a tax professional when in doubt-especially if your business spans multiple states or involves international clients.
With proper planning and documentation, a 1099 filer can legally reduce their tax burden by thousands of dollars annually. The key lies in consistency, accuracy, and understanding the difference between a business expense and a personal one.
