What Is an 1120 Tax Form?

The IRS Form 1120 is provided for American domestic corporations to report their credits, special deductions , gains, losses, and income. The 1120 tax form also helps with tax computation so corporations can determine how much federal income tax they will need to pay for the year. If a corporation determines it will have a tax liability of $500 or more, it will need to make estimated tax payments using Form 1120-W in addition to the 1120 form.

Businesses should understand that the income tax paid by corporations is calculated using the corporate income tax rate of 21%, which is not the same as a personal income tax. IRS Form 1120 should be filed by all corporations or those taxed as corporations, except for S corporations .

Who Files IRS Form 1120?

The 1120 tax form is used by the Internal Revenue Service ( IRS ) to help corporations determine how much tax they owe for the previous year, also known as their income tax liability . Some will also refer to this form as the U.S. Corporation Income Tax Return .

Specifically, this form should be used by all businesses in the United States classified as C corporations . Corporations classified as S corporations will use Form 1120-S instead. S corporations must also fill out Schedule K -1 for each shareholder they have. This form gets included with the individual returns.

It's important to note that all corporations in the U.S. must file the 1120 IRS form , even if they will not have taxable income , including corporations in bankruptcy. The only corporations that don't need to file this form are those exempt under Section 501. These organizations will instead file an information return .

The following entities must file tax form 1120:

  • Any business that has elected to be taxed as a corporation will need to fill out an 1120 tax form . This includes farming corporations, which will use the form to report their income and losses. These businesses must also make sure to fill out Form 8832, which will get attached to the IRS Form 1120.
  • Limited liability companies ( LLCs ) will need to file this form in certain situations, specifically if they have elected to be taxed as a corporation.
  • A foreign-owned domestic disregarded entity may also have to pay taxes using this form. If a foreign individual or corporation owns 100% of a domestic disregarded entity, the domestic disregarded entity will be treated separately from its international owner. The foreign owner or corporation must file Form 5472 to attach to their Form 1120.
  • Ownership in a financial asset securitization investment trust (FASIT) also impacts filing. Corporations with ownership interest in this type of trust need to fill out Form 1120.

Those who need to fill out the 1120 tax form may find that they need to fill out an additional IRS form , depending on their situation. For example, Form 1120 Schedule N is for foreign operations of U.S. corporations. On the other hand, Form 1120 Schedule D is for capital gains and losses from the past fiscal year .

What Are the Special 1120 Forms?

There are specific forms that some corporations may need to file. These include:

  • Regardless of whether a political group is a tax- exempt organization , they will use Form 1120-POL if they have taxable income from their organization.
  • Cooperative organizations, such as farmers' cooperatives, also have a special form known as Form 1120-C.
  • A foreign corporation will need to file Form 1120-F.
  • Life insurance corporations file Form 1120-L.
  • Certain real estate corporations, such as residential real estate management, condominium management, and timeshare management that decides to function as a homeowners association, need to file Form 1120-H.

I Just Started My Business. Do I Still Need to File?

Corporations must file taxes soon after they form. Even if you just went through the process of incorporation , you will need to file your taxes by the 15th day of the fourth month after the end of the tax year . This remains the rule even if the period is extremely short for you.

If you find that you need a tax extension, filing Form 7004 can help you attain the extra time you need to file your taxes. However, Form 7004 needs to be filled out by your original tax due date .

Therefore, businesses should familiarize themselves with their filing deadlines as soon as they establish their new corporation. They might owe forms and taxes to the IRS very quickly after the business entity forms.
