How 1099 Taxes Work: A Beginner's Guide

What “1099” means

If a company or a client pays you as an independent contractor instead of an employee, the IRS considers you self-employed. The name comes from the forms that report that income: the Form 1099-NEC for services, and the Form 1099-K for payments through apps and card processors.

Compared with a W-2 job, two big things change:

1. Nobody withholds taxes from your pay. You receive the full amount, and paying the IRS is your job.
2. You pay both halves of Social Security and Medicare. An employer normally pays half; now you are the employer.

The two taxes you owe

Self-employment tax. This is Social Security and Medicare for people who work for themselves: 15.3% of 92.35% of your profit. The Social Security part (12.4%) stops at $184,500 of earnings in 2026; the Medicare part (2.9%) has no cap. You owe it once your net earnings reach $400, which is also the point where you have to file a return.

Federal income tax. The same brackets everyone uses, applied after your deductions: half of your self-employment tax, the standard deduction ($16,100 if single, $32,200 if married filing jointly in 2026), and the qualified business income (QBI) deduction of up to 20% of your business profit.

Example. A single freelancer with $40,000 of profit in 2026 owes about $5,652 of self-employment tax and $1,775 of federal income tax: $7,427 in total, or about 19% of the profit.

Most states also tax this income. Texas, Florida and a few others do not have a state income tax.

How much to set aside

The safest habit is to move a fixed share of every payment into a separate savings account the day you get paid. The right share depends on your profit, your filing status and your state, but in the example above it is about 19% of profit for federal taxes alone. Our guide on how much to set aside has the share for other profit levels and with a W-2 job.

Instead of guessing, run your numbers in our 1099 tax calculator. It shows your total federal tax, your effective rate and how much to put aside each month.

Lower your tax with business expenses

You are taxed on your profit, not on everything you were paid. Every legitimate business expense lowers both your income tax and your self-employment tax. Common ones:

• Vehicle use for work. In 2026 the IRS standard rate is 72.5¢ per mile from January to June and 76¢ from July to December. Or you can deduct your actual car expenses instead.
• Phone and internet, for the share you use for work.
• Supplies, tools and equipment, from a laptop to insulated delivery bags.
• Software and subscriptions you need for the job.
• Fees that apps or payment processors keep from your earnings.
• A home office, if part of your home is used regularly and only for work.

See the full list for your line of work in our guide to 1099 deductions by profession.

Some deductions lower income tax but not self-employment tax: half of the self-employment tax itself, health insurance premiums for self-employed people, and contributions to a SEP IRA or Solo 401(k).

Keep records from day one. Save receipts, keep a mileage log with the date, miles and purpose of each trip, and use a separate bank account for business money. If the IRS asks, you need to show where each number came from (see what to do if you get a letter from the IRS).

Pay during the year: quarterly estimated taxes

Because nothing is withheld, the IRS expects you to pay as you earn if you will owe $1,000 or more for the year. For the 2026 tax year the due dates are April 15, 2026, June 15, 2026, September 15, 2026 and January 15, 2027:

Our quarterly estimated tax calculator tells you how much to pay by each date and how to catch up if you missed one.

Filing your return

Your 2026 return is due April 15, 2027 (or October 15, 2027 with an extension, which gives you more time to file but not to pay). All the dates are in our tax calendar for the self-employed. As a 1099 worker you file Form 1040 with:

• Schedule C: your business income and expenses, and the resulting profit.
• Schedule SE: your self-employment tax.
• Schedule 1: adjustments such as half of the self-employment tax.

By February 1, 2027 you may receive forms from the businesses that paid you: a 1099-NEC from each client that paid you $2,000 or more in 2026, and a 1099-K from payment platforms in some cases. Report all of your income, including payments that did not come with a form.

If you also have a W-2 job

Your wages count toward the $184,500 Social Security limit, so if the two together pass it, you pay less self-employment tax. And tax withheld from your paycheck counts toward what you owe on your 1099 income: raising your withholding with a new Form W-4 can cover it and spare you the quarterly payments.

Common beginner mistakes

• Spending the whole payment and facing a big bill in April.
• Skipping quarterly payments and paying a penalty on top of the tax.
• Mixing personal and business money, which makes deductions hard to prove.
• Forgetting cash, tips or small clients because no form arrived.
• Not tracking miles until the end of the year.

Quick checklist

1. Open a separate account and move part of every payment into it.
2. Track income, expenses and miles as you go.
3. Pay quarterly estimated taxes on time.
4. Collect your 1099 forms in January and compare them with your records.
5. File Schedule C, Schedule SE and Form 1040 by April 15, 2027.
