Simplified IRS Business Tax Filing Online

All business, except partnerships, needs to file a corporate tax return with the IRS. The form you used to file depends on your business entity type. Partnerships also file taxes under an information return in the US. 

Generally, the business tax return for LLCs in the US is due on April 15. Also, in rare circumstances, a two-month extension is also available, subject to consent from the IRS. Additionally, the corporate tax is typically due by the 15th day of the fourth month of the following tax year of the corporation. However, a corporation whose fiscal tax year ends on June 30 should file the taxes by the 15th day of the third month after the completion of its tax year. 

To file an IRS business tax filing in the US, you generally need your Social Security number or individual tax ID number (ITIN), bank account, and routing numbers to get a tax refund for taxes you have paid or a direct deposit, your adjusted gross income, and exact tax refund amount if you filed your tax return from the last year, your current address proof, Forms W-2, 1099 or other information returns and your name on record with the US Social Security Administration (SSA).

To qualify for an S Corporation, your business should first be a local corporation with fewer than 100 shareholders, who can only be individuals, certain estates or trusts, or other than businesses or non-resident aliens. Also, the business should only issue one class of stock and not be a business that is ineligible for S Corporation, such as a financial institution. If your business meets the following criteria, then it qualifies as an S Corporation. 

If the LLC is a corporation, in this scenario, normal corporate tax rules will be applicable on the LLC, and it should fill out a Form 1120, U.S. Corporation Income Tax Return. Depending on elections made by the LLS and members involved, the IRS will treat it as either a corporation, a partnership, or as part of the tax return of the owner of the LLC.
