I started working as an independent contractor for a company and was being paid $13,000 per month under my personal name. In May, I formed a business and began operating under the business name, but the company continued paying me under my personal name. Out of each $13,000 payment, I was sending $3,000 per month in estimated taxes. Now that I’m filing my taxes, I’m trying to determine the correct structure:
Should I file one Schedule C for the $40,000 earned from January through April under my personal name, and a second Schedule C for the $80,000 earned from May through December under the business name?
Here’s the clean, correct way to think about this without creating problems on your tax return.
Your situation, simplified
You earned:
- $13,000 per month as an independent contractor
- Paid $3,000 per month in estimated taxes
- Started using a business name in May, but the company still paid you under your personal name
This is the key:
The IRS does not care what “name” you operated under. They care who received the money and what EIN/SSN it was reported under. If the company paid you under your personal name and SSN, then ALL income for the year goes on ONE Schedule C, even if you were “doing business as” a business name.
Do you file two Schedule Cs?
No — not unless the company switched to paying your business EIN. Since they paid you personally the entire time:
- You file ONE Schedule C
- Report the full $120,000 of income
- Use your business name as a DBA if you want
- But it is still one business, because the IRS sees it as one business
What about the taxes you paid ($36,000)?
Those are estimated tax payments. You do not put them on Schedule C. You report them on:
- Form 1040 – Estimated Tax Payments Section
- They reduce your total tax owed for the year.
Why you should NOT split the income
If you try to file:
- $40,000 on one Schedule C.
- $80,000 on another
…but the company issued one 1099‑NEC under your personal SSN, the IRS will see: One Schedule C matches the 1099. The other Schedule C has unmatched income. This triggers a CP2000 audit letter. You don’t want that. Correct filing structure for your year:
- Schedule C
- Gross income: $120,000
Business name:
You can list your business name as “Business Name (DBA)”. But the SSN stays the same.
Estimated taxes
Report the $36,000 you paid on Form 1040
This reduces your tax bill or increases your refund
Going forward
If you want the business to be separate:
- Give the company your business EIN
- Have them issue future payments to the business
- Then you can file a separate Schedule C or elect S‑Corp later
Let’s break this down cleanly so you file correctly and avoid IRS mismatch letters.
Key principle
The IRS only cares about who received the money and what EIN/SSN the payer reported it under.
So the real question is:
Did the company switch to paying your business EIN starting in May,
or
Did they keep paying you under your personal SSN, but just wrote your business name on the check or invoice?
These two situations are treated VERY differently.
Scenario A — They paid your BUSINESS EIN starting in May
If this is what happened, then:
You DO file two Schedule Cs
Because you technically had two separate businesses:
- Jan–Apr
- Paid under your personal SSN
- File Schedule C #1
- Report $40,000 income
- May–Dec
- Paid under your business EIN
- File Schedule C #2
- Report $80,000 income
The $36,000 in taxes you paid. These are estimated tax payments and go on Form 1040, not on either Schedule C.
- This setup is clean and correct, because the IRS will see:
- One 1099‑NEC issued to your SSN
- One 1099‑NEC issued to your EIN
- Two Schedule Cs that match those forms
- No mismatch. No audit letter.
Scenario B — The employer paid your PERSONAL SSN the entire year. Even if the checks said your business name, if the payer still used your SSN, then:
You CANNOT file two Schedule Cs
You must file ONE Schedule C with the full $120,000.
Why?
Because the IRS will receive one 1099‑NEC under your SSN.
If you split the income, the IRS will see:
- One Schedule C matches the 1099
- The other Schedule C has “extra” income
- This triggers a CP2000 audit letter
The $36,000 still goes on Form 1040
As estimated tax payments.
Which scenario applies to you?
Here’s the deciding factor:
Did the company ask for your business EIN and issue a new W‑9?
If yes, then you file two Schedule Cs.
If no, then you file one Schedule C.
Your statement: “the company started paying me under the business name”
This phrase can mean two different things:
Meaning 1 (legal change):
They switched to your business EIN
→ Two Schedule Cs
Meaning 2 (cosmetic change):
They still paid your SSN, but wrote your business name on the payment
→ One Schedule C
Most companies do NOT switch EINs unless you gave them a new W‑9.
Your next step
Tell me this one detail:
Did the company issue you TWO 1099‑NECs (one to your SSN and one to your EIN), or just ONE?
That answer determines the exact filing structure.
Did the company switch to paying your business EIN starting in May,
Here’s the clean, decisive answer you need so we can lock in the correct tax structure.
Did the company switch to paying your business EIN starting in May?
To answer that, you only need to check one thing:
Did you give the company a new W‑9 with your BUSINESS EIN on it?
Because that is the only way a payer legally switches from paying “you personally” to paying “your business.”
If you did not submit a new W‑9, then the payer could not switch to your business EIN — even if the checks or invoices showed your business name.
Here’s how to confirm it 100%:
Look at the 1099‑NEC they issued for the year.
You will see one of two things:
Scenario 1 — The 1099‑NEC shows your BUSINESS EIN
If the 1099‑NEC lists:
- Your business name
- Your business EIN
Then YES — they switched to paying your business starting in May.
You file two Schedule Cs
Schedule C #1 (Jan–Apr): $40,000 under your SSN
Schedule C #2 (May–Dec): $80,000 under your business EIN
Your $36,000 estimated taxes still go on Form 1040.
Scenario 2 — The 1099‑NEC shows your PERSONAL SSN
If the 1099‑NEC lists:
- Your personal name
- Your SSN
Then NO — they did not switch to your business EIN. Even if the checks said your business name, the IRS sees it as you personally.
You file ONE Schedule C
Report the full $120,000
List your business name as a DBA if you want. But it is still one business for tax purposes. Your $36,000 estimated taxes still go on Form 1040.
Your next step (the only thing that matters now)
Tell me:
What EIN/SSN is printed on the 1099‑NEC you received?
If the company switched to paying your BUSINESS (EIN) starting in May, here is the correct and clean IRS‑approved structure for your tax filing.
This is the version that avoids mismatches, CP2000 audit letters, and Schedule C errors.
Your correct filing structure
You will file TWO Schedule Cs
Schedule C #1 — Personal (Jan–Apr)
Because you were paid under your SSN during this period.
- Income: $40,000
- Business name: leave blank or list “Your Name”
- EIN: leave blank (use SSN)
- Expenses: any expenses from Jan–Apr
Schedule C #2 — Business (May–Dec)
Because the company switched to your business EIN starting in May.
- Income: $80,000
- Business name: your LLC/DBA
- EIN: your business EIN
- Expenses: any expenses from May–Dec
This matches exactly how the IRS sees your income:
One payer reporting income to your SSN
One payer reporting income to your EIN
Two Schedule Cs = perfect alignment.
2. The $36,000 you paid in taxes. These were estimated tax payments. They do NOT go on Schedule C. They go on:
Form 1040 → “Estimated Tax Payments” section
This reduces your total tax owed for the year.
3. Why this structure is correct
Because:
The IRS sees two different taxpayer IDs. Each ID must have its own Schedule C. Splitting the income exactly where the payer switched IDs keeps everything clean. If you tried to combine them, the IRS would see:
- A 1099‑NEC issued to your SSN
- A 1099‑NEC issued to your EIN
- But only one Schedule C
- That mismatch triggers an automatic IRS letter.
- You’re avoiding that by filing two Schedule Cs.
Here is the exact, line‑by‑line structure for how to file both Schedule Cs and how to report your $36,000 estimated tax payments on Form 1040.
This is the cleanest, IRS‑aligned version based on:
Jan–Apr paid under your SSN
May–Dec paid under your business EIN
Let’s lock it in.
SCHEDULE C #1 — Personal (Jan–Apr)
Purpose: Report income paid to your SSN before the business EIN switch.
Header Section
Name of proprietor: Your personal name
Social Security Number: Your SSN
Business name: Leave blank OR put “Your Name”
EIN: Leave blank
Business address: Your address
Principal business code: Choose the code that matches your industry
Accounting method: Cash
Material participation: Yes
Part I — Income
Line 1 (Gross receipts): 40,000
Line 2–7: Fill in if you had returns/allowances or other adjustments
Line 7 (Gross income): 40,000
Part II — Expenses
Enter any expenses you incurred from January to April only:
Examples:
- Advertising
- Supplies
- Home office
- Mileage
- Phone/internet
- Contract labor
- Software
- Professional fees
Line 31 — Net profit
= $40,000 minus expenses
This flows to Form 1040, Schedule 1, Line 3.
SCHEDULE C #2 — Business (May–Dec)
Purpose: Report income paid to your business EIN.
Header Section
Name of proprietor: Your personal name
Business name: Your LLC/DBA
EIN: Your business EIN
Business address: Business address
Principal business code: Same industry code
Accounting method: Cash
Material participation: Yes
- Part I — Income
Line 1 (Gross receipts): 80,000 - Line 7 (Gross income): 80,000
- Part II — Expenses
Enter expenses from May to December only. - Same categories as above.
Line 31 — Net profit
= $80,000 minus expenses
This also flows to Form 1040, Schedule 1, Line 3.
FORM 1040 — Estimated Tax Payments ($36,000)
Your $3,000 per month × 12 months = $36,000 goes on:
Form 1040, Line: “Estimated tax payments”
This is in the Payments section.
This amount reduces your total tax owed.
Important:
- You do NOT put estimated taxes on Schedule C
- You do NOT split the $36,000 between the two businesses
It all goes on Form 1040, because estimated taxes are personal payments
