The IRS requires you to report all side hustle income, but most gig workers leave money on the table by overlooking legitimate deductions. Taking full advantage of business write-offs can slash both your income tax and self-employment tax bills by hundreds or thousands of dollars annually.
Side hustle deductions work differently than standard deductions. When you claim business expenses, you reduce your taxable income directly, which lowers both federal income tax and the self-employment tax you owe on that income. This double benefit makes deductions far more valuable than the standard deduction alone.
Common deductions for gig workers include home office space, vehicle mileage, supplies, equipment, and software subscriptions. If you use part of your home exclusively for your side business, you can deduct a portion of rent or mortgage interest, utilities, and home maintenance costs. The simplified home office method allows $5 per square foot, up to 300 square feet.
Mileage deductions apply to business-related driving. The 2025 standard mileage rate for business use sits at 67.5 cents per mile. Track every trip related to client meetings, supply runs, or deliveries. Use a mileage log app or spreadsheet to document dates, routes, and purposes.
Equipment and supplies purchased for your business qualify as deductions. Laptops, cameras, tools, and office furniture generally qualify if they cost under $2,500 and are used primarily for business. Higher-cost items may need to be depreciated over multiple years.
Subscription services, software, and online tools used for your business also count. This includes accounting software, design platforms, scheduling apps, and payment processors.
The key is keeping meticulous records. Save receipts, invoices, and logs throughout 2025. When tax season arrives, you'll be able to itemize these expenses and
