Quick Answer
File Form 4868 by April 15, 2027 through IRS e-file, tax software, or mail to get an automatic extension until October 15. You must estimate and pay any taxes owed — the IRS charges 8% annual interest on unpaid balances even with a valid extension.

How to file Form 4868 step by step
Filing Form 4868 is straightforward, but freelancers must handle it correctly to avoid penalties. You have three filing options, and the form itself is just one page.
Option 1: E-file through IRS (recommended)
1. Go to IRS.gov/efile and select "Free File" or use approved tax software
2. Enter basic information: Name, SSN, address, filing status
3. Estimate your tax liability for 2026
4. Calculate payment needed: Total tax minus payments already made (quarterly estimates + withholding)
5. Choose payment method: Direct debit, credit/debit card, or EFTPS
6. Submit by April 15, 11:59 PM (your time zone)
Option 2: Tax software integration
Most tax software (TurboTax, H&R Block, FreeTaxUSA) lets you file Form 4868 directly:
Example: $90,000 freelancer filing Form 4868
Sarah earned $90,000 in freelance income in 2026 and made $18,000 in quarterly estimated payments. Here's her Form 4868 calculation:
Line 4 — Estimate of total tax liability:
Line 5 — Total payments:
Line 6 — Balance due: $5,200 ($23,200 - $18,000)
Line 7 — Amount to pay: $5,200 (to avoid interest)
Sarah files Form 4868 electronically and pays $5,200 by April 15. She now has until October 15 to file her complete return.
