First-Year Freelancer Taxes: What to Do Your First Year Self-Employed (2026)

Published: June 18, 2026 · Reading time: 8 min

TL;DR: Your first year self-employed, the tax system changes under you: no withholding, self-employment tax on top of income tax, quarterly estimated payments, and a Schedule C to file. Do five things in order — (1) set aside 25–30% of every payment from day one; (2) decide whether to get an EIN (free, keeps your SSN private); (3) start quarterly estimated taxes if you'll owe $1,000+; (4) track every expense and mile from the first dollar; (5) file Schedule C + Schedule SE. The first four make the fifth easy.

Your first freelance payment hits your account and it feels like a win — until you realize no one took taxes out, no one will, and the IRS expects you to figure that out yourself. The first year self-employed isn't harder than a W-2 job; it's just unfamiliar. Here's the whole thing, in the order you should do it.

Why the First Year Feels Like a Trap

At a W-2 job, taxes were invisible: your employer withheld income tax, paid half your Social Security and Medicare, and you maybe got a refund. As a freelancer, all of that is now your job. Two surprises in particular:

No withholding. Every dollar arrives untaxed. The bill is real; it's just deferred.
Self-employment tax. You now pay both halves of Social Security and Medicare — 15.3% on net self-employment income — on top of regular income tax. This is the line item that shocks most first-year freelancers.

The fix isn't complicated, but it has to start early. Waiting until April is how first-year freelancers end up owing thousands they already spent.

Step 1: Set Aside 25–30% From Day One

The single most important habit: the moment a payment lands, move a slice of it into a separate savings account you don't touch.

A safe default is 25–30% of your net income (what's left after business expenses). That covers the 15.3% self-employment tax plus federal income tax, with room for state tax in most places. High earners or high-tax states should lean toward 30–35%.

Don't overthink the exact percentage in year one — the discipline of separating the money matters more than precision. You can true it up at filing.

Step 2: Decide on an EIN

You don't legally need an EIN as a sole proprietor with no employees — your Social Security number works. But an EIN is free, takes a few minutes on the IRS site, and lets you put a business number on every W-9 and 1099 instead of handing out your SSN. For privacy alone, most first-year freelancers get one.

This is also the moment to think about structure — for almost everyone starting out, a sole proprietorship is the right default, and you can revisit an LLC or S-corp later when profit justifies it.

Step 3: Start Quarterly Estimated Taxes

Because nobody withholds for you, the IRS wants its money as you earn it — through four estimated tax payments due in April, June, September, and January. If you'll owe $1,000 or more for the year, skipping them can trigger an underpayment penalty even if you pay in full at filing.

There's a first-year break in your favor: safe-harbor rules cap the penalty, and if your prior year had little or no tax liability, you may owe no penalty for underpaying this year. Even so, paying quarterly is the cleanest path — it spreads the cost and kills the April lump sum. Use the estimated tax calculator to size each payment.

Step 4: Track Every Expense and Mile From the First Dollar

Deductions are how a freelancer's tax bill comes back down — but only the ones you can document. From your very first business expense, capture it:

Receipts for software, supplies, equipment, a home office, professional services — each tagged to its Schedule C line
Mileage at the 2026 IRS rate of $0.725/mile, logged with date, miles, and business purpose in a contemporaneous log
Startup costs from before you opened — partly deductible in year one

The first-year trap here is reconstructing it all in April from memory and a messy inbox. A receipt photographed when it happens is a deduction; a vague memory is not. See the full expense-tracking guide for the system.

Step 5: File Schedule C and Schedule SE

At year-end, two new forms ride along with your Form 1040:

Schedule C — your business's profit or loss: income minus all those tracked expenses
Schedule SE — self-employment tax on the net profit

If you're not sure you even need to file Schedule C, start here. If you did steps 1–4 during the year, filing is mostly transcription: your tracked totals become the lines on the form. This is also where the QBI deduction can knock up to 20% off your qualified business income. Walk the whole filing sequence with the how-to-file guide and the freelancer tax checklist.

The First-Year Mistakes That Cost the Most

Spending the gross. Treating the full payment as income, then having nothing set aside. Step 1 prevents it.
Skipping quarterlies. A penalty plus a five-figure April bill, all at once.
No records. Real deductions lost because there's no receipt or mileage log behind them.
Mixing money. Running business and personal through one account makes every number a guess — open a separate business account early and keep business and personal expenses apart.

Frequently Asked Questions

What do I need to do about taxes in my first year of freelancing?

Five things, in order: (1) set aside 25–30% of every payment for taxes from your first invoice, because no one is withholding for you; (2) decide whether you need an EIN (free from the IRS, and worth getting to keep your SSN off forms); (3) start making quarterly estimated tax payments if you'll owe $1,000 or more, to avoid an underpayment penalty; (4) track every business expense and business mile from day one, since deductions only count if you can document them; and (5) file Schedule C (profit or loss) and Schedule SE (self-employment tax) with your Form 1040 at year-end. Doing the first four during the year makes the fifth easy.

How much should a first-year freelancer set aside for taxes?

A safe default is 25–30% of your net self-employment income (income minus business expenses) set aside as you get paid. That covers self-employment tax of 15.3% plus federal income tax, with room for state tax in most states. Higher earners or those in high-tax states should lean toward 30–35%. The key habit is to move the money the day a payment lands, into a separate savings account you don't touch — first-year freelancers most often get burned by spending the gross and having nothing set aside when the bill arrives.

Do first-year freelancers have to pay quarterly estimated taxes?

Generally yes, if you expect to owe $1,000 or more in tax for the year. Because there's no employer withholding, the IRS wants tax paid as you earn it through four estimated payments (due in April, June, September, and January). Skipping them can trigger an underpayment penalty even if you pay in full at filing. There's a first-year wrinkle in your favor: safe-harbor rules can limit the penalty, and if your prior year had little or no tax liability you may owe no penalty for underpaying. Still, paying quarterly is the cleanest way to avoid both the penalty and a brutal lump sum in April.

Do I need an EIN as a first-year freelancer?

Not legally, if you're a sole proprietor with no employees — you can use your Social Security number. But an EIN is free, takes minutes to get from the IRS website, and lets you put a business number on W-9s and 1099s instead of your SSN, which is better for privacy and looks more professional to clients. Many first-year freelancers get one for that reason alone. You'll definitely need an EIN if you hire employees, form certain entity types, or open a business bank account that requires one.

What can a first-year freelancer deduct, and from when?

From your very first business dollar, you can deduct ordinary and necessary business expenses against your income on Schedule C: software, supplies, a home office, business mileage at $0.725/mile in 2026, phone and internet (business share), professional services, and more. Costs incurred before you officially opened can qualify as startup costs, partly deductible in year one. The catch is documentation — a deduction only survives if you can show the receipt or mileage log behind it, so the single most valuable first-year habit is capturing every receipt and logging every business trip from the start.
