FAQs

What is a Form 1120 in Delaware?

Form 1120 is a crucial tax document utilized by corporations in the United States to disclose their income, gains, losses, deductions, and credits for federal income tax goals.

What does Delaware C Corp mean?

Who is required to submit Tax Form 1120?

Regardless of taxable income, every US-based domestic corporation must file tax Form 1120. 

The following entities fall under the obligation to file tax Form 1120:

  1. Businesses opting for corporate taxation. These businesses must also complete Form 8832 and include a copy of Form 1120.
  2. Limited liability companies (LLCs). LLCs file Form 1120 only if they've chosen corporate taxation. Partnership LLCs use Form 1065, while single-member LLCs typically file taxes through the owner's personal federal tax return.
  3. Farming corporations. They are required to file Form 1120 to report their income/losses.
  4. Corporations with an ownership interest in a FASIT (Financial Asset Securitization Investment Trust).

Additionally, some types of corporations may need to complete additional forms, such as Form 1120 (Schedule N), for foreign operations in the U.S. Small corporations might not be required to fill out these additional forms.
