Freelancer taxes 101: what changes the moment you get your first 1099

For years, taxes happened to you automatically. Your employer withheld income tax, Social Security, and Medicare from every paycheck, and by the time your W-2 showed up in January, most of the work was already done. Then you took on your first freelance client, the check arrived with nothing withheld, and tax season stopped being automatic (and fun).

Here's what changes the moment self-employment income enters the picture, and what to do about each one.

Nobody is withholding for you anymore

A client paying you as a contractor doesn't withhold income tax, Social Security, or Medicare from your payment. That's not an oversight. It's the entire distinction between an employee and an independent contractor. The full amount you're paid is yours to receive, and the full tax bill on it is yours to plan for.

This is where new freelancers get caught off guard. A $5,000 project fee isn't $5,000 in spendable income. A meaningful chunk of it needs to be set aside before it ever hits your personal budget.

You now owe self-employment tax, on top of income tax

As an employee, you paid half of your Social Security and Medicare tax (7.65% of your wages), and your employer paid the other half. As a self-employed person, you pay both halves yourself, a combined 15.3% self-employment tax: 12.4% for Social Security on the first $184,500 of net self-employment income for 2026, plus 2.9% for Medicare with no cap. If your income from self-employment and wages combined exceeds $200,000 ($250,000 married filing jointly), an additional 0.9% Medicare tax applies to the excess.

Self-employment tax is calculated on 92.35% of your net earnings, not the full amount, and half of what you pay is deductible when you file. Neither of those things make the number small, though. This tax exists in addition to regular income tax on your profit, not instead of it.

Estimated payments become your job

Without an employer withholding on your behalf, the IRS expects you to pay tax as you earn it, four times a year, through estimated payments. For 2026, the due dates are April 15, June 16 (shifted from June 15, which falls on a weekend), September 15, and January 15, 2027. Miss these consistently and underpayment penalties start adding up, even if you pay everything you owe by the filing deadline.

A rough rule of thumb: set aside 25% to 30% of your net freelance income for taxes as it comes in, more if you're in a higher bracket or your state has income tax. We cover the exact math, including how to use your prior year's return to set a safe target, in a separate post linked below.

The flip side: now you can deduct business expenses

As an employee, your work expenses mostly weren't deductible. As a self-employed person, ordinary and necessary business expenses reduce your taxable income before self-employment tax and income tax are calculated. Software subscriptions, a portion of your phone bill, business mileage, a home office used regularly and exclusively for work, contractor payments, professional development. All of it lowers the number your tax bill is based on, as long as you can document it.

This is the part new freelancers underuse the most. Deductions only work if you're tracking the expense in the first place, which means a business bank account and a habit of logging what you spend, starting with your first invoice, not next April.

You might not get a 1099 at all, and it doesn't matter

Starting with payments made in 2026, clients only have to send you a Form 1099-NEC if they paid you $2,000 or more in the year, up from the old $600 threshold. If you did $1,500 of work for three different clients, none of them may send you a form. That income is still taxable, and you're still responsible for reporting all of it, whether or not a 1099 ever shows up in your inbox. The 1099 is a reporting requirement for the payer, not the trigger for your tax liability.

The same logic applies to money that comes through payment apps like PayPal, Venmo, or Stripe. Those platforms only issue a Form 1099-K once you cross $20,000 and 200 transactions in a year. Below that, you won't get a form, but the income doesn't disappear from your tax return because nobody reported it to the IRS on your behalf.

Recordkeeping stops being optional

When taxes were automatic, sloppy records mostly cost you convenience. Now they cost you deductions you can't prove and a tax bill you can't calculate accurately until it's too late to plan around it. Open a separate business bank account before you cash your first freelance check, save receipts as you go, and reconcile that account monthly so you always know where you stand.
