Business tax return: which form applies to you?

We help you find out which federal return your business files, based on how it is organized and classified with the IRS.

What is this guide?

Your business's federal return depends on how it is organized and how the IRS classifies it. Not every LLC files the same form.

This guide helps you find your case. Before we begin, we confirm which form applies to your business.

Which form does your business file?

You work for yourself or have a single-owner LLC

Generally, Schedule C with your personal return (Form 1040).

Partnership or LLC with two or more members

Form 1065, with a Schedule K‑1 for each partner, unless it elected to be taxed as a corporation.

C corporation or LLC that elected to be taxed as a corporation

Form 1120.

Corporation or LLC with an S election in effect

Form 1120-S, with a Schedule K‑1 for each shareholder.

Business with employees

In addition to its return, payroll Forms 941 (each quarter) and 940 (each year).

See “Self-employed (1099 and Schedule C)”

See “Form 1065 — Partnerships and LLCs”

See “Form 1120 — C corporations”

See “Form 1120-S — S corporations”

See “Payroll taxes (941 and 940)”

How is an LLC classified?

If an LLC does not file an election with the IRS, it is classified by default based on the number of members: with one owner, it is reported on the owner's return; with two or more, it is treated as a partnership. An LLC can elect to be taxed as a corporation with Form 8832, or as an S corporation with Form 2553.

What information do we need to find out?

  • Company documents: certificate of formation and Operating Agreement, if any.
  • IRS letter with your EIN, if you have one.
  • Any election filed with the IRS (for example, Form 8832 or 2553).
  • Income and expenses for the year, with bank statements and receipts.
  • Last year's return, if you have it.

Please do not send Social Security numbers, full EINs, or documents through the form on this page. After you request the service, we will email you the questionnaire and the list of documents.
