Do I Need to File Form 1120 If My LLC Had No Income?

This is one of the most common questions from international founders. The short answer is: yes, you must file Form 1120 even if your LLC had absolutely no income.

Why zero-income filing is required

If your LLC elected corporate tax treatment (or is treated as a corporation by default), the IRS expects an annual Form 1120 regardless of revenue. The IRS needs to know about your entity's financial position, even if that position is $0.

The Form 5472 connection

For foreign-owned LLCs, the real obligation isn't just Form 1120 — it's Form 5472. The IRS wants to know about all "reportable transactions" between your US entity and its foreign owner. This includes:

• •Capital contributions (even your initial LLC funding)
• •Loans from you to the LLC or vice versa
• •Paying for LLC expenses from personal funds
• •Any payments between you and the LLC

That $100 you transferred to your LLC's bank account to keep it open? That's a reportable transaction.

What a zero-income filing looks like

Your Form 1120 will show:

• •$0 gross receipts
• •$0 (or minimal) deductions
• •$0 taxable income
• •$0 tax due

Attach Form 5472 reporting any transactions between you and the LLC.

Penalties for skipping it

• •Form 1120 late filing: 5% of unpaid tax per month (which is $0 if you owe nothing, but the IRS can still assess minimum penalties)
• •Form 5472 late filing: $25,000 per form. This is the one that hurts. The IRS is serious about foreign ownership reporting.

Deadlines

Same as regular Form 1120: April 15 for calendar-year filers. File Form 7004 for an automatic 6-month extension to October 15.
