Independent Contractor Guide

More than 64 million Americans work as independent contractors. Being a 1099 worker gives you freedom and tax advantages — but also comes with responsibilities that W-2 employees don't have.

Worker Classification

The IRS and Department of Labor use a multi-factor test to determine if a worker is an employee (W-2) or independent contractor (1099). Key factors: who controls when/where/how the work is done, whether the business provides tools/equipment, whether you have other clients, and whether you have the opportunity for profit or loss.

Misclassification penalties: the employer may owe back taxes, penalties, and interest for failing to properly classify workers. Form SS-8 can be filed for an official IRS determination.

Taxes for 1099 Workers

• Self-Employment Tax: 15.3% (12.4% Social Security + 2.9% Medicare) on net earnings. W-2 employees split this with employers — 1099 workers pay both halves.
• SE Tax Deduction: You can deduct half of your SE tax (7.65%) from your adjusted gross income.
• Quarterly Estimated Taxes: Due April 15, June 15, September 15, January 15. Penalty for underpayment: based on current interest rate (IRS failure-to-pay rate, updated quarterly). Safe harbor: pay 100% of last year's tax or 90% of this year's.
• Schedule C: Report business income and expenses. Profit is net income subject to SE tax.

Key Deductions

• Home office (dedicated space, regular/exclusive use)
• Health insurance premiums (deducted on Schedule 1, not Schedule C)
• Retirement contributions (Solo 401(k) or SEP IRA)
• Business equipment and software
• Internet and phone (business portion)
• Vehicle mileage (standard rate: $0.70/mile for 2026) or actual expenses
• Travel, meals (50% deductible), and education
• Professional services (accountant, attorney, website designer)

Contracts & Getting Paid

• Always have a written contract — scope of work, payment terms, deadlines, ownership of IP.
• Get paid via: Direct deposit, wire transfer, PayPal, Stripe, Wise, or Zelle. Avoid checks (slow/loss risk).
• Late payment terms: Net-30 is standard. Add 1.5% monthly late fee. Have clients sign a statement of work (SOW) with late payment terms.
• Retainers: Bill monthly or weekly for ongoing work. Helps smooth cash flow.
• Deposits: Ask for 25-50% upfront for projects over $1,000.

Benefits (You're on Your Own)

• Health insurance: Buy through ACA marketplace. Premiums are tax-deductible (SEHIP deduction on Form 1040).
• Disability insurance: Protects against loss of income if you can't work.
• Retirement: Solo 401(k) (up to $69,000 in 2026) or SEP IRA (up to $69,000 or 25% of comp).
• Paid time off: Build vacation and sick leave into your rate. Your rate should be ~30-40% higher than an equivalent salaried position to account for self-funded benefits.

State-Specific Rules

• California (AB5): Strict "ABC test" for worker classification. Most workers are presumed employees unless the business proves all three ABC factors.
• New York: Strong independent contractor protections. Unemployment insurance rules vary.
• Massachusetts: Also uses an ABC test.
• Illinois, New Jersey, Connecticut: Have tightened contractor misclassification rules.
