Understanding Schedule C categories, IRC Section 179, and IRS compliance

Frequently Asked Questions About 1099 Write-Offs
What is the difference between a tax deduction and a tax credit for 1099 contractors?
A tax deduction (write-off) lowers your taxable business profit on IRS Schedule C, reducing both your 15.3% SECA self-employment tax and income tax. A tax credit reduces your final tax bill dollar-for-dollar after taxes are computed.
Can 1099 contractors deduct 100% of their mobile phone and internet bills?
You can only deduct the business-use percentage of your cell phone and internet. For example, if you use your phone 70% for client calls/work and 30% for personal use, you can legally write off 70% of your annual phone bill on Schedule C.
How does the Section 179 equipment deduction work in 2026?
Under IRS Section 179, self-employed contractors can write off 100% of qualifying business equipment (such as laptops, cameras, monitors, and servers) in the year purchased rather than depreciating it slowly over 5 to 7 years.
How does the self-employed health insurance deduction work?
Under IRC § 162(l), eligible self-employed individuals can deduct 100% of health, dental, and qualifying long-term care insurance premiums for themselves, their spouse, and dependents as an 'above-the-line' deduction on Schedule 1 (Form 1040).
What is the 2026 IRS standard business mileage rate?
The IRS standard business mileage rate is 67 cents per mile. To claim it, maintain a contemporaneous mileage log recording the date, business destination, purpose, and total miles driven.
