🧮 $400 Net Income Calculator
Determine if you've met the $400 IRS filing threshold for self-employment tax
STEP 1 Calculate Gross Business Income
Sum all revenue from freelance work, independent contracting (1099), or your side hustle.
STEP 2 Subtract Ordinary Business Expenses
Deduct valid business expenses from your gross income to arrive at your Net Profit.
STEP 3 Apply the IRS Adjustment & Check Threshold
Calculated as 15.3% of your adjusted net SE income. This is an estimate — consult a tax professional for your exact liability.
📋 Example Calculation Breakdown
| Metric | Scenario A (Below Threshold) |
Scenario B (Meets Threshold) |
|---|---|---|
| Gross Business Income | $600.00 | $1,200.00 |
| Business Expenses | − $200.00 | − $750.00 |
| Net Profit | $400.00 | $450.00 |
| IRS Adjustment (× 92.35%) | $369.40 | $415.58 |
| Must File & Pay SE Tax? | ❌ No | ✅ Yes |
💡 Key Rules to Keep in Mind
- The Filing Requirement: If your calculated net income after the 92.35% adjustment is $400 or more, you must file Schedule SE alongside Form 1040.
- Even Without a 1099: You must report this income and track the $400 threshold even if you did not receive an official Form 1099 from your clients.
- Other Income Matters: If you have to file a tax return for another reason (like a regular W-2 job), you must report your self-employment profit even if it falls below the $400 mark.
