Not tax advice. This guide is general information about US federal taxes for the 2026 tax year (the return you file in 2027). Rules depend on your situation and your state. Check with a tax professional before you file.
Tax season is harder for freelancers than for employees for one simple reason: nobody withholds tax from your pay. You are the one who tracks income, sets money aside, pays during the year and files at the end. The good news is that most of the work is routine. If you keep a few habits all year, filing becomes an afternoon of paperwork rather than a week of digging through emails.
This guide walks through what to gather, which forms to expect, the deadlines that matter and how to avoid the most common penalties.
Key takeaways
As a freelancer you report business income and expenses on Schedule C and pay self-employment tax (Schedule SE) once your net earnings reach $400.
If you expect to owe $1,000 or more, you generally need to pay estimated tax four times a year: April 15, June 15 and September 15, 2026, and January 15, 2027.
You can avoid an underpayment penalty by paying at least 90% of this year's tax or 100% of last year's (110% if last year's AGI was over $150,000).
Report all your income, even if you never get a 1099. Clients only have to send a 1099-NEC for payments of $2,000 or more in 2026.
An extension (Form 4868) gives you until October 15 to file, not to pay.
How freelancers are taxed, in one paragraph
Your freelance profit (income minus business expenses) goes on Schedule C. That profit is subject to regular income tax and to self-employment tax, which covers Social Security and Medicare: 15.3% on 92.35% of your net earnings, with the Social Security part capped each year. You can deduct half of your self-employment tax. The self-employment tax calculator shows what that means for your numbers, and the freelance tax calculator estimates your total bill and quarterly payments.
Step 1: Gather your income records
Start with what you earned. You need a complete list of every payment you received during the year, from every client and platform.
Your invoices. Each paid invoice is a record of income: who paid, how much and when. If you invoice in one place, this list already exists.
Bank and payment statements. Card processors (Stripe, PayPal, Square), payment apps and bank transfers. Use them to check that every invoice was actually paid, and to catch income you never invoiced.
Marketplace reports. Upwork, Fiverr and similar platforms publish annual earnings summaries.
Don't rely on tax forms to tell you what you earned. They arrive late, they can be wrong, and many clients won't send one at all.
Step 2: Know which 1099 forms to expect
Two forms report freelance income to you and to the IRS:
Form | Who sends it | When you get one (2026 payments) |
|---|---|---|
1099-NEC | US business clients who paid you for services | If a client paid you $2,000 or more during the year (the threshold was $600 before 2026) |
1099-K | Payment platforms and card processors, such as PayPal or Stripe | If you received more than $20,000 in more than 200 transactions through that platform |
Clients pay you by card or through a platform? Those payments are reported on a 1099-K by the platform, not on a 1099-NEC by the client, so the same income isn't counted twice.
Forms 1099-NEC are due to you by January 31. In 2027, January 31 falls on a Sunday, so the deadline moves to Monday, February 1. If a form shows the wrong amount, ask the sender to issue a corrected one.
Whatever forms you receive, the rule doesn't change: you report all of your income, with or without a 1099.
Step 3: Collect your business expenses
Every legitimate business expense lowers both your income tax and your self-employment tax, so it pays to have them all in one place:
Receipts and card statements for software, equipment, supplies and subscriptions
Your mileage log, if you drive for work
Home office measurements and costs, if you claim a home office
Phone and internet bills, with the share you use for business
Payment processing fees, bank fees and business insurance
Health insurance premiums and retirement contributions (these are claimed on your personal return, not Schedule C)

Step 4: Check your estimated tax payments
If you expect to owe at least $1,000 when you file, the IRS generally expects you to pay during the year in four installments. For the 2026 tax year:
Payment | Covers income earned | Due date |
|---|---|---|
1st | January 1 – March 31, 2026 | April 15, 2026 |
2nd | April 1 – May 31, 2026 | June 15, 2026 |
3rd | June 1 – August 31, 2026 | September 15, 2026 |
4th | September 1 – December 31, 2026 | January 15, 2027 |
You don't have to pay the 4th installment if you file your 2026 return and pay all the tax you owe by February 1, 2027.
How to avoid a penalty. You generally won't owe an underpayment penalty if your payments during the year add up to at least:
90% of the tax you owe for 2026, or
100% of the tax shown on your 2025 return (110% if your 2025 adjusted gross income was more than $150,000).
The second option is the easiest to plan around: take last year's total tax, divide by four and pay that each quarter. If your income jumped this year, you'll owe the difference in April, but without a penalty.
A practical habit: every time a client pays an invoice, move a fixed share of it to a separate savings account for taxes. The freelance tax calculator gives you a starting percentage.
Step 5: File, or file an extension
Your 2026 federal return is generally due April 15, 2027. You can file yourself with tax software, use IRS Free File if you qualify, or work with a tax professional.
If you need more time, Form 4868 extends the deadline to file until October 15, 2027. It does not extend the deadline to pay. Estimate what you owe and pay it by April 15, or you'll be charged interest and possibly a late-payment penalty on the balance.
Don't forget your state. Most states with an income tax have their own return and their own estimated tax rules, and the deadlines usually line up with the federal ones.
A month-by-month tax calendar for freelancers
When | What to do |
|---|---|
Every month | Send invoices on time, record payments, file receipts, move a share of each payment to your tax savings |
April, June, September, January | Pay estimated tax (see the table above) |
Early January | Close the books for the year: reconcile invoices against bank deposits, total your expenses |
By February 1, 2027 | Expect your 1099-NEC forms; check them against your records |
February – March | Gather everything, prepare your return or hand it to your accountant |
April 15, 2027 | File and pay, or file Form 4868 and pay what you estimate you owe |
When to get professional help
Plenty of freelancers file on their own. It's worth paying a tax professional if:
It's your first year freelancing, or your income changed a lot
You're considering an S corporation or another business structure
You work in several states or have clients abroad
You received an IRS notice or need to amend an earlier return
You simply don't want to spend the time
Bring clean records and a good preparer can do the job quickly, which also keeps the bill down.
Keep it simple all year
The easiest tax season starts with how you invoice. When every invoice lives in one place, with its status and payment date, your income list for Schedule C is already done. Onigiri keeps every invoice as Draft, Sent, Overdue or Paid, and marks card payments Paid automatically. On the PRO plan, income tracking shows what came in and when. The free plan includes 3 invoices a month, no credit card required. Start for free.
