How the 1099 Self-Employment Tax Formula Works

🚗 The 2026 Mileage Rule

The standard IRS mileage rate for business travel is 67 cents per mile. You can deduct every mile driven while waiting for rides/orders, traveling to pickup, and during delivery. Keep a digital mileage log.

💰 The 15.3% SE Tax Shock

W-2 employees split FICA taxes 50/50 with their employer. 1099 contractors pay both sides: 12.4% for Social Security + 2.9% for Medicare (total 15.3%) on 92.35% of net profit.

🛡️ The 50% SE Tax Deduction

The IRS allows you to deduct half of your self-employment tax as an adjustment to income on Form 1040, lowering your federal taxable income before brackets are applied.

⏰ Form 1040-ES Deadlines

If you expect to owe more than $1,000 in taxes, pay quarterly: April 15, June 15, September 15, and January 15 of the following year to prevent penalties.
