What is Form 1120S?
Form 1120S is the tax form S corporations use to file their federal income tax return (not to be confused with Form 1120 for C corporations). Every S corp needs to file one, including LLCs that are taxed as S corps.
You can download Form 1120S directly from the IRS website. Or if you use tax software, you can find it there too.
Information you’ll need to file Form 1120S
Before you jump in to the form, you’ll need to have the following items handy:
- Your date of incorporation
- A list of your products or services
- Your business activity code
- Your Tax ID or Employer Identification Number (EIN)
- The date you elected S corp status: This will be January 1 if your business operates on a calendar-year basis. It will be on the first day of your fiscal year if you operate on a fiscal-year basis.
- A profit and loss statement and a balance sheet: You can create these manually or if you use Bench, we’ll create them for you.
- Your accounting method: You’ll indicate on the form whether you use cash or accrual accounting.
- Independent contract payments: Any payments to independent contractors totaling at least $600 for the year will need to be reported on the form. You also must provide contractors with 1099 forms.
