Your business income tax return has been prepared and it's all ready for the final steps: filing your return and paying your taxes. Filing and paying are separate processes, but in some cases, you can combine them. 

Before You File and Pay

You have finished your business tax return and you are ready to send it in and pay your taxes. But first, there are a couple of things you need to know: 

Keep an eye on the due date. We all know that taxes are due on April 15, but what if that day falls on a Saturday or a Sunday? IRS tax due dates will change every year, due to holidays and weekends. Check the due dates for the tax return you are filing for the current tax year. 

Make sure the tax payment and the return get there on time. You need to know when the IRS considers a tax return or payment to have been received. 

Do an error check to make sure you haven't missed anything that will get your return sent back by the IRS. 

Business Income Tax Filing Methods

Business Combined with Personal

If you file your business income tax on Schedule C along with your personal tax return, or if you are filing a Schedule K-1 from your partnership or S corporation distributions, here are some options: 

  • The most common way to file online is to use e-file, which is available from tax software programs or your tax preparer can e-file for you. 
  • You can also file a paper return, with or without payment. Where and how you file your paper return depends on your location and whether you are paying and filing together. 

Business Separate from Personal

If you are filing a tax return for a partnership, corporation, or S corporation, here are your options: 

  • You can e-file using one of the options available from the IRS, depending on the type of business tax return you are filing. 
  • Your tax preparer can e-file for you or can use business tax return software to prepare and file your return. 

Payment Options for Paying Business Taxes Online

Using a Credit or Debit Card

You can pay by credit or debit card through one of the service providers listed by the IRS. These service providers charge a fee for transmitting tax payments. The two service providers listed by the IRS are:

  • Official Payments Corporation at 1-800-2PAYTAX (1-800-272-9829) or visit the Official Payments Web site.
  • Link2Gov at 1-888-PAY1040 (1-888-729-1040) or visit the Pay1040.com Web site.

Payments may be transmitted by credit or debit card for Form 1040 (including your Schedule C for your self-employed income) and you may also transmit payments in this manner when you file an application for extension on Form 4868. The credit or debit card payment option is not applicable to payments for partnership tax returns on Form 1065, corporate tax returns on Form 1120, or s-corporation tax returns on IRS Form 1120S.

Using the IRS Electronic Federal Tax Payment System (EFTPS)

You can use the Electronic Federal Tax Payment System (EFTPS) to pay all federal tax payments. You will first need to enroll in the system.

Using Electronic Funds Transfer

You can pay your business taxes through electronic funds transfer in one of two ways:

  • Through your tax preparer
  • By using tax preparation software such as TaxCut or TurboTax

Mailing Your Tax Payment

You can mail your tax payment along with return directly to the IRS, and you can use this option if you are paying at the same time as you are filing for an extension on Form 4868 or Form 7004.

If you are filing your taxes using Form 1040, you will need to complete and attach the payment voucher, Form 1040-V, to your payment. If you are mailing in your payment, be sure to address it to U.S. Treasury (or United States Treasury), and include the business Tax ID Number or your Social Security Number on the check.
