What is Schedule SE (Form 1040)?

Schedule SE (Form 1040), Self-Employment Tax, is the IRS schedule that figures the Social Security and Medicare tax self-employed people owe in place of the payroll taxes an employer would normally withhold. You generally must file it if your net earnings from self-employment - typically from Schedule C profit or your share of partnership income on Schedule K-1 - were $400 or more, regardless of your age or whether you already collect Social Security or Medicare. The schedule applies the 12.4% Social Security rate up to the annual wage base ($176,100 for 2025) and the 2.9% Medicare rate with no ceiling, while subtracting any W-2 Social Security wages you already paid. It also computes the deduction for one-half of your self-employment tax, which flows to Schedule 1. JustFill opens the official 2025 Schedule SE PDF in your browser, uses AI to detect each line, and lets you type or dictate your figures - even on scanned copies - with no Adobe required.

Field-by-field breakdown

What each section of Schedule SE (Form 1040) asks for. JustFill’s AI will detect these fields automatically when you upload the PDF — review the breakdown below so you know what to enter.

Line 1a - Net farm profit or (loss)

Net farm profit or loss from Schedule F and farm partnerships; most non-farm filers leave this blank.

Line 2 - Net profit or (loss) from Schedule C

Your non-farm self-employment profit, carried from Schedule C (line 31) or a partnership Schedule K-1.

Line 3 - Combine lines 1a, 1b, and 2

Total net earnings before the 92.35% adjustment - the starting point for the SE tax calculation.

Line 4 - Net earnings subject to SE tax (line 3 x 92.35%)

Multiplies line 3 by 0.9235; if under $400 you generally owe no self-employment tax.

Line 7 - Maximum Social Security wage base

Pre-printed cap of combined wages and self-employment earnings subject to the 12.4% Social Security tax ($176,100 for 2025).

Lines 8a-8d - Social Security wages already taxed

W-2 Social Security wages and tips (plus Forms 4137/8919 amounts) that reduce how much of the cap remains for SE tax.

Line 10 / Line 11 - Social Security and Medicare portions

Line 10 applies 12.4% to the smaller of line 6 or 9; line 11 applies 2.9% Medicare tax to all of line 6.

Line 12 / Line 13 - Total SE tax and the deduction

Line 12 adds lines 10 and 11 for total self-employment tax (to Schedule 2); line 13 is the deductible half (to Schedule 1).

Common mistakes to avoid

  • 1Forgetting to multiply line 3 by 92.35% on line 4 and instead figuring tax on the full net profit, which overstates the tax owed.
  • 2Skipping the deduction for one-half of self-employment tax on line 13, leaving money on the table on Schedule 1.
  • 3Not reducing the Social Security base by W-2 wages on lines 8a-9, causing self-employed people who also held a job to overpay the 12.4% portion.
