What is IRS Form 1120?

Form 1120 is the U.S. corporate income tax return. If you’re a Delaware C-Corp, even if you haven’t made a single dollar, you need to file it. Yes, even with $0 revenue and no customers.

Do I Really Need to File It?

If you’re incorporated as a C-Corp, the IRS expects that 1120. No revenue? No problem. You still file a zero return. Waiting will only trigger late fees, even if you owe nothing.

When Is It Due?

• April 15 for calendar-year C-Corps

• File Form 7004 to extend to October 15

What Happens If I Don’t File?

• Penalties start at $435/month, up to 12 months

• You might lose good standing with investors

• It’ll definitely mess with future funding rounds

What You’ll Need:

• EIN (Employer Identification Number)

• Date of incorporation

• Ownership info (cap table)

• Revenue/expense summary, even if it’s $0

Life Hacks for Founders:

• Set a Google Calendar reminder 2 weeks before April 15

• Use TaxHero AI to auto-file or extend (7004)
