The W-2 and the 1099 are both year-end tax documents that report income, but they represent fundamentally different employment arrangements and have very different implications for what you owe.
What a W-2 covers
A W-2 (Wage and Tax Statement) is issued by any employer who paid you as an employee. It shows:
- Total wages, tips, and other compensation paid to you
- Federal income tax withheld
- Social Security and Medicare (FICA) taxes withheld
- State and local income tax withheld, if applicable
Because your employer withholds taxes throughout the year with every paycheck, you often get a refund when you file, or owe a small amount if your withholding was slightly off. The employer also pays half of your FICA taxes (7.65%) on your behalf. You see only your half deducted from your paycheck.
Employers must mail or electronically deliver your W-2 by January 31 of the following year. If you worked for three employers in a year, you’ll receive three W-2s and need to combine them on your return.
What a 1099 covers
A 1099 is a family of forms used by payers who are not your employer. The most common types for individual filers:
- 1099-NEC (Nonemployee Compensation): freelance, contract, consulting, or gig income. Any client who paid you $600 or more during the year is required to send one.
- 1099-MISC: miscellaneous income including rent, prizes, and certain royalties.
- 1099-INT: interest income from banks and credit unions over $10.
- 1099-DIV: dividends from stocks and mutual funds.
- 1099-B: proceeds from the sale of stocks, bonds, or other securities.
- 1099-R: distributions from retirement accounts, pensions, or annuities.
When you receive a 1099-NEC, nothing was withheld. The full amount is taxable income, and it’s up to you to set aside and pay the taxes.
The self-employment tax difference
This is where the 1099 situation gets significantly more expensive than W-2 employment.
As an employee, you pay 7.65% in FICA taxes (6.2% Social Security up to the wage base, 1.45% Medicare) and your employer matches that 7.65%. As a self-employed person, you pay both halves: 15.3% self-employment tax on net self-employment income up to the Social Security wage base ($176,100 for 2026), plus 2.9% above that. This is reported on Schedule SE and added to your income tax bill.
The one offset: you can deduct half of your self-employment tax as an above-the-line adjustment on Schedule 1, which reduces your adjusted gross income.
Take $60,000 in income as an example:
- As a W-2 employee: you paid $4,590 in FICA taxes; your employer paid another $4,590. Your net pay reflects $4,590 deducted from your check.
- As a 1099 contractor earning the same $60,000: you owe $8,478 in self-employment tax (15.3% of 92.35% of net income, after the deductible portion calculation), plus income tax on top.
Estimated quarterly taxes
W-2 employees have taxes withheld with every paycheck, so they rarely owe a penalty at filing time. Self-employed filers and those with significant 1099 income have no withholding, so the IRS requires quarterly estimated tax payments if you expect to owe $1,000 or more for the year.
The quarterly due dates for 2026 income are:
- April 15, 2026
- June 16, 2026
- September 15, 2026
- January 15, 2027
Skipping estimated payments leads to an underpayment penalty even if you pay in full when you file. Use IRS Form 1040-ES to calculate and mail payments, or pay electronically through IRS Direct Pay at IRS.gov/directpay.
What to do if you receive both
Many people have a W-2 from a day job and one or more 1099s from side work or investments. Both types of income get combined on your Form 1040. The W-2 income goes on Line 1; 1099-NEC income flows through Schedule C (profit or loss from business) before landing on the 1040. Interest and dividend income from 1099-INT and 1099-DIV go on Schedule B.
Track all 1099 income as it comes in during the year, not just when forms arrive in January. Payers are only required to send a 1099-NEC if they paid you $600 or more, but you owe tax on all income regardless of whether a form was issued.
