Tax Write-Offs for Every Self-Employed Profession (2025)
What is a tax write-off?
A tax write-off — also called a tax deduction — is an expense that the IRS allows you to subtract from your gross income before calculating how much tax you owe. If you earn $80,000 and have $20,000 in valid write-offs, you're only taxed on $60,000. The more legitimate write-offs you claim, the lower your tax bill.
For self-employed workers, freelancers, and gig workers, write-offs are especially powerful. Unlike W-2 employees, you pay both the employee and employer portions of Social Security and Medicare taxes (called self-employment tax). Deductions reduce the income subject to both income tax and self-employment tax, making each dollar of write-offs more valuable.
Write-offs for self-employed individuals are claimed on Schedule C (Profit or Loss from Business), which is attached to your Form 1040. The IRS requires that expenses be "ordinary and necessary" — meaning common in your line of work and helpful for your business. You must be able to substantiate all claimed deductions with records.
