Common first-year mistakes
Mistake 1: Wrong line number
Some people put quarterly payments on line 25a (federal withholding). Line 25a is only for taxes withheld from paychecks by employers.
Mistake 2: Including January twice
Don't include your January 2027 payment if you already counted it toward 2026. Each payment only counts once.
Mistake 3: Splitting by quarters
Don't list individual quarterly amounts. Add them all up and put the total on line 26.
What happens after you enter line 26
The IRS compares your reported amount on line 26 to their records of payments received. If there's a mismatch:
What you should do
1. Gather all payment records: Bank statements, confirmation numbers, or canceled checks
2. Add up total federal quarterly payments made for 2026 (including January 2027 payment)
3. Enter the total on Form 1040, line 26
4. Keep records for at least 3 years in case of IRS questions
5. Use our quarterly estimator to plan better payments for next year
Most first-time filers find that line 26 is straightforward once they know where it is. The key is having accurate records of what you actually paid.
Key takeaway: Quarterly estimated tax payments go on Form 1040, line 26. Enter the total of all federal quarterly payments made for 2026, including the January 2027 payment, and keep detailed payment records.

Side hustlers: Two payment lines to fill out
When you have both W-2 employment and freelance income, you'll use two different lines in the Payments section:
Line 25a: Federal tax withheld from W-2 jobs (from box 2 of your W-2)
Line 26: Quarterly estimated tax payments for freelance income
Real example: Teacher with tutoring business
Sarah teaches full-time ($48,000 salary) and runs a tutoring business ($15,000 income):

Why both lines matter for side hustlers
The IRS needs to see both payment types because:
1. Different tax treatment: W-2 withholding covers all taxes; quarterly payments usually just cover income tax
2. Penalty calculations: The IRS calculates underpayment penalties based on total payments from both sources
3. Refund processing: Separate tracking helps the IRS match payments to their records
Most side hustlers discover they need to increase their quarterly payments because freelance income often pushes them into higher tax brackets, and they still owe self-employment tax on the 1099 income.
Key takeaway: Side hustlers use both line 25a (W-2 withholding) and line 26 (quarterly payments) - keep these payment types separate and report each on its designated line.

Returning freelancers: Line 26 nuances
If you've been making quarterly payments for multiple years, line 26 has some additional considerations beyond just entering your payment total.
Applied overpayments from prior year
Line 26's full label is "2026 estimated tax payments and amount applied from 2025 return." If you had an overpayment on your 2025 return and chose to apply it to 2026 estimated taxes, include that amount in your line 26 total.
Example:
Payment timing considerations
For returning filers, payment timing becomes more critical:
Experienced freelancers typically develop payment systems (automatic transfers, calendar reminders) to ensure consistent reporting on line 26 year after year.
Key takeaway: Returning freelancers should include both quarterly payments and any overpayment applied from the prior year on line 26, and maintain consistent payment timing for easier record-keeping.
