– Articles of Incorporation
– Previous Tax Return
– Business Account Statements
– Account Records
– Annual Payroll Report
– Vehicle Usage & Maintenance
– Credit & Debit Card Records

If you are able to access the documents named above while you are filing taxes, this is all of the information that you will have access to:

  • Business Accounting Software
  • Federal Tax ID
  • Date of Incorporation or Registration
  • S Corp Election Date

Your Business Structure

Sole Proprietorship & Single-Member LLC

If a business is registered as a Sole Proprietorship or a Single-Member LLC, it serves as an extension of whoever is running the business. In other words, you file your business taxes via Schedule C, and this is turned in with the standard individual FORM 1040 filed by everyone. Due to this, the deadlines and due dates follow the dates associated with nonbusiness owners standard FORM 1040. The year-end is December 31st, while Schedule C and FORM 1040 have a deadline of April 15th.

Partnership & Multi Member LLC

Filing taxes for a partnership can involve a few more moving parts, but it is very doable. It is important to remember that FORM 1065, the form used for Partnerships and Multi Member LLC’s, is an information return. When you file FORM 1065, tax will not be paid or calculated from that specific form. Because of this, Schedule K-1 Forms are turned in with FORM 1065 to determined individual income/loss for the year for each partner. Beyond this, taxes owed by the business are paid by individual partners or LLC members. Concerning who pays what, this is determined in the terms and conditions of the partnership or multi-member agreement.

S Corporation

If your business is registered as an S Corporation, you will be filing an information return. S Corps use FORM 1120S for their information returns. With FORM 1120S, you will be required to turn in your Schedule K-1 as in the example above. Although a majority of S Corporations technically have one owner, in the case that yours does not, all co-owners are expected to file according to the steps above.

Note: Multi-Member LLC’s have the option to elect to be taxed as either an S Corporation, or Corporation. If this option is not exercised, the default for the IRS is to assume that your business is filing as a partnership.

C Corporation

C Corporations, simply referred to as Corporations, have the luxury of choosing any date that they want as their year-end day. To make the process easy, most corporations pick the end of a quarter. After the date is determined, corporate tax returns are due on the fourth month and fifteenth day immediately following the year-end. For example, if March 31st were the year-end, corporate taxes would be due on July 15th.
