What Can You Write Off as a 1099 Contractor?
As a 1099 contractor, you may be able to write off ordinary and necessary expenses that are directly connected to your business. Common review categories include home office costs, business mileage, software, tools, subscriptions, phone, internet, professional services, education, insurance, and retirement planning costs.
The key question is not only whether an expense appears on a deduction list, but whether you can show the business purpose, keep records, and separate business use from personal use. This page is for general educational purposes and is not tax advice. Contractors should consult a qualified tax professional for their specific situation.

Common Expense Categories to Review
Tools and Software
Subscriptions, professional software, cloud services, communication tools, and work platforms may be part of business expense planning.
Insurance and Professional Costs
Liability insurance, licensing, continuing education, accounting, legal support, and payment processing fees are common review categories.
Equipment and Workspace
Computers, devices, supplies, workspace costs, and internet or phone allocations require careful records and fact-specific review.
Travel and Mileage
Client travel, lodging, transportation, and mileage can be relevant when they are directly tied to business activity and properly documented.
Marketing and Client Acquisition
Website costs, ads, portfolio tools, lead generation, proposals, and professional memberships may support contractor income.
Education and Certifications
Training, certifications, continuing education, and licenses may be relevant when they maintain or improve business skills.
Home Office Deduction
A home office may be relevant when part of your home is used regularly and exclusively for business. Contractors should keep records and review IRS rules before assuming a home workspace qualifies. Shared personal spaces, occasional work areas, and poorly documented expenses can be harder to support.
Business Mileage and Vehicle Expenses
Business mileage, parking, tolls, and vehicle expenses may matter when travel is directly tied to client work or business operations. Commuting and personal driving are usually treated differently, so documentation is important.
Software, Tools, and Subscriptions
Many 1099 contractors use paid software, cloud tools, design tools, accounting platforms, communication apps, project management systems, and professional subscriptions. These costs should be tracked separately from personal spending.
Phone and Internet
Phone and internet costs can be partly business-related when they are used for client communication, marketing, remote work, or business operations. Contractors should avoid treating the entire bill as business use unless the facts support it.
Health Insurance and Retirement Contributions
Some self-employed workers review health insurance premiums as part of tax planning. Rules can depend on eligibility, business structure, other coverage, and the full tax return.
Self-employed retirement contributions may also reduce taxable income depending on the plan type and contribution limits. Common planning topics include SEP IRA, Solo 401(k), and traditional IRA rules.
Professional Services and Education
Accounting, bookkeeping, legal support, tax preparation, professional memberships, licensing, certifications, and continuing education can be relevant contractor tax write-offs when they support the business. Keep receipts, invoices, course descriptions, and notes about how each cost relates to your work.
Expenses That Are Usually Not Deductible
Personal meals, commuting, personal clothing, entertainment, personal phone use, non-business travel, and expenses without records are common problem areas. If an expense has mixed personal and business use, keep clear documentation and ask a qualified tax professional.
