IRS Form 1120 · For C-Corporations
Your C-Corporation’s Form 1120 Income Tax Return
Form 1120 is the income tax return a U.S. C-Corporation files each year. We review your filing requirement, prepare the return from your financial records, walk you through it, and file it. (Own an LLC rather than a corporation? See our Foreign-Owned LLC IRS Filing package instead.)
- Filing requirement assessed first
- Return prepared from your records
- You review before anything is filed
- Works for companies we did not form

Why It Matters
Why Form 1120 Matters
Form 1120 is how a U.S. corporation reports its income, deductions and tax to the IRS. Filing obligations depend on your entity type and activity — the first job is establishing what actually applies to you.

We assess your filing requirement before preparing anything.

Common Mistakes We See
Assuming no income means no return
Many corporations still have a filing obligation in a year with little or no activity.
Confusing this with the LLC package
A foreign-owned single-member LLC does not file a real 1120 — it files Form 5472 attached to a pro forma 1120. That is our $149 package, not this service.
Leaving books until the deadline
A return can only be as good as the records behind it. Rushed books cause amended returns.

Frequently Asked Questions
Does my corporation have to file Form 1120?
U.S. C-Corporations generally have an annual federal filing obligation. Whether it applies to your entity depends on its type and circumstances — our assessment establishes that before we prepare anything.
Do I still file if the company made no money?
In many cases yes. A corporation can still have a filing obligation in a year with little or no activity. We confirm what applies to you.
What is the difference between this and the Foreign-Owned LLC package?
This is the genuine corporate income tax return that an actual C-Corporation files. A foreign-owned single-member LLC is a disregarded entity — it files Form 5472 attached to a pro forma Form 1120, which is a cover form rather than a real return. That is our separate $149 package.
Can you file if another provider formed my company?
Yes. We assist eligible companies regardless of who handled the original formation.
Is the tax I owe included in the fee?
No. The fee covers preparing and filing the return. Any tax, penalties or interest owed to the IRS is separate and paid by you directly.
My books are a mess — can you still help?
Yes, but the return depends on the records behind it. We can quote catch-up bookkeeping first so the return is built on something accurate.
