1099 vs. W-2: A Tax Guide for Contractors & Gig Workers

If you drive for a rideshare app, freelance, contract, play gigs around Nashville, or run any kind of side hustle, you've probably received a 1099 instead of — or in addition to — a W-2. That one form changes how your taxes work, and misunderstanding it is how a lot of people end up with a painful bill in April. Here's what you actually need to know.

What's the difference between a 1099 and a W-2?

A W-2 means you're an employee. Your employer withholds income tax, Social Security and Medicare from every paycheck and sends it to the IRS for you. A 1099 (usually 1099-NEC or 1099-K) means you're an independent contractor or self-employed. Nothing is withheld — you receive the full amount, and you're responsible for the taxes yourself.

The big one: self-employment tax

As a W-2 employee, you and your employer split the 15.3% Social Security and Medicare tax — you only see about half of it. When you're self-employed, you pay the entire 15.3% yourself, on top of regular income tax. This "self-employment tax" is the number-one reason 1099 workers are surprised at tax time. The upside: you can deduct half of it, and 1099 income opens the door to business deductions a W-2 employee can't take.

You have to pay as you go

Because no one is withholding for you, the IRS expects you to send in quarterly estimated taxes throughout the year. Skip them and you can owe an underpayment penalty even if you pay in full in April. A simple habit that saves the day: move 25–30% of every payment you receive into a separate savings account for taxes.

Deductions that lower your 1099 tax bill

This is where self-employment can actually work in your favor. Ordinary and necessary business expenses reduce the income you're taxed on:

• Mileage and vehicle costs for business driving
• A portion of your phone and internet
• Equipment, tools and software you use for work
• The home office deduction if you qualify
• Self-employed health insurance premiums
• Retirement contributions (a SEP-IRA or Solo 401k)

Keeping simple, consistent records all year — see our guide to bookkeeping basics — is what makes sure you actually capture these.

Should you form an LLC or S-corp?

Many 1099 workers start as sole proprietors, which is perfectly fine. But once your self-employment income grows, forming an LLC and potentially electing S-corp status can reduce that 15.3% self-employment tax. We break the math down in LLC vs. S-Corp in Tennessee.

The bottom line

1099 income means more freedom and more deductions — but also more responsibility. If your side hustle is turning into real income, or you just don't want an April surprise, a quick conversation with a tax pro pays for itself.
