1099 & SELF-EMPLOYED TAXES

What Is a 1099 Employee? How Your Taxes Work, and What You Can Deduct

A plain-language guide to what a 1099 actually changes about your taxes, and the deductions that lower what you owe.

1099 Employee vs. W-2: What the Form Actually Means

A W-2 is the form an employer sends when they have withheld taxes from your paycheck all year and treat you as an employee. A 1099 (specifically Form 1099-NEC for freelance or contract work) is what a client sends when they paid you as an independent contractor, with no taxes withheld along the way.

That is the real distinction: employee versus self-employed, not a special tax status of its own. If you are receiving 1099s, the IRS considers you self-employed, and you report that income on Schedule C, a form that lists your business income and the expenses you can subtract from it before your taxes are calculated.

Getting a 1099 does not automatically mean you have a formal “business” in the legal sense. Freelancers, gig drivers, consultants, and side-hustlers all typically fall into this category, often without ever registering an LLC.

The Taxes a 1099 Worker Actually Owes

As a 1099 worker, you owe two separate taxes on your net income (your revenue minus your deductible business expenses):

  • Income tax, at your regular federal (and state, if applicable) tax bracket, the same as any W-2 employee.
  • Self-employment tax, which covers the Social Security and Medicare contributions your employer would normally split with you. As a 1099 worker, you pay both halves yourself, currently 15.3% of your net self-employment income.

That second tax is the one that surprises most new 1099 workers. It is a big part of why 1099 taxes can feel higher than a W-2 job at the same pay, even though the income tax portion is calculated the same way either way. The upside: every deductible business expense lowers your net income, which lowers both taxes at once.

Quarterly Estimated Taxes, in Brief

Because no one is withholding taxes from a 1099 paycheck, the IRS expects you to send in estimated payments four times a year, based on what you expect to owe. Skip them, and you may owe a small penalty later, even if you pay your full balance by the April deadline.

A rough version of the math: take your expected net income for the quarter, subtract your deductions, then apply your income tax bracket plus the 15.3% self-employment tax. Every deduction you can document lowers that number.

Here is a simplified example. Say a freelancer expects $15,000 in net quarterly income before deductions:

$15,000 net income − $1,500 in documented business mileage deductions
$13,500 taxable net incomea lower number means less owed at both the income tax and self-employment tax level

That $1,500 is doing real work: it is the difference between paying tax on $15,000 and paying tax on $13,500. Mileage is usually the deduction most 1099 workers underuse, mainly because they are not logging trips consistently. We will get into why that matters shortly. If you would rather have software estimate your full quarterly number for you, a 1099 estimated tax calculator can help you sanity-check the math against your actual numbers, though the deductions above are what move that number the most.

The Deductions That Move the Needle

Not every deduction is worth the same. A few consistently make the biggest dent in a 1099 worker’s tax bill:

  • Mileage. If you drive for client meetings, deliveries, site visits, or any other business purpose, you can deduct those miles at the IRS standard rate, 76 cents per mile for 2026. For most 1099 workers who drive regularly, this is often the single largest deduction available, sometimes larger than every other expense combined.
  • Home office. If you have a dedicated space used regularly and exclusively for your business, you may be able to deduct a portion of your rent or mortgage, utilities, and related costs. See our guide to the home office deduction for the exact requirements.
  • Phone and internet. The business-use portion of your phone and internet bills is deductible. If you use your phone about half the time for work, you can typically deduct roughly half the bill.
  • Supplies and small equipment. Software subscriptions, a laptop used for work, office supplies, and similar business necessities.

If your work involves overnight trips, client dinners, or conference travel, see our guide to business travel expense deductions for what else you can write off.

Mileage tends to be the one people leave money on the table with, mostly because it requires tracking trips as they happen rather than reconstructing them at tax time.

Why Mileage Is Usually the Biggest One

A driving-heavy 1099 job (real estate, deliveries, home services, sales) can easily rack up thousands of business miles a year. At 76 cents per mile, even 5,000 miles works out to a $3,800 deduction, real money against both your income tax and self-employment tax bill.

The catch is that mileage deductions only hold up if you have a log that would satisfy the IRS, in case you are ever asked to provide one. That means a record of the date, destination, business purpose, and miles for each trip, kept close to when the trip happened rather than rebuilt from memory in March.

If you are not sure whether your work qualifies, our guide to who qualifies for the mileage deduction covers the eligibility rules in detail, and are commuting miles tax deductible settles the drive the IRS most often disallows. If you already know you qualify but need a system for logging trips, our guide on how to calculate mileage for taxes walks through exactly how.

Frequently Asked Questions

What is a 1099 employee?▼
Technically, there is no such thing, since a 1099 means you are self-employed rather than an employee. But the term is commonly used for anyone paid via a 1099 instead of a W-2, meaning no taxes are withheld and you handle your own income tax and self-employment tax.
Do 1099 employees pay more taxes?▼
Not a higher rate overall, but you do pay both halves of Social Security and Medicare (the 15.3% self-employment tax) that an employer would normally split with you. That is a big reason 1099 taxes can feel higher, even though your income tax bracket works the same way it would on a W-2.
What can I write off?▼
The most common deductions are mileage, home office costs, the business-use portion of your phone and internet, and supplies or software you use for work. Mileage is usually the largest deduction for anyone who drives regularly for business.
What is a 1099-K?▼
A 1099-K is a different form, sent by payment platforms like PayPal, Venmo for business, or a marketplace app when your processed payments cross a reporting threshold. It reports payment volume, not necessarily your taxable income, so you will still calculate your actual profit and expenses from your own records, ideally with help from a 1099 tax calculator with deductions or a tax professional if the numbers get complicated.
