Millions of taxpayers file their tax returns and other important documents with the Internal Revenue Service (IRS) every year.

While many people file their taxes electronically, some still prefer using fax machines to submit their forms.

Knowing the correct IRS fax numbers for submitting your documents is essential because sending your forms to the wrong entity could lead to significant delays in processing your returns.

Worst case scenario, it results in the loss of crucial, confidential information.

This article will explore important fax numbers for the IRS to know when faxing your tax documents to the IRS.

What is an IRS fax number?

An IRS fax number is a specific phone number that you can use to send certain documents through a fax machine.

The IRS offers different fax numbers for various purposes.

There are separate numbers for sending tax returns, filing tax extensions, or providing supporting documents for an ongoing audit.

Using an IRS fax number guarantees several benefits for you and your business.

For example, it can be faster than sending documents through regular mail, which can take several days or weeks to arrive and be processed.

Additionally, using a fax machine allows you to confirm that the IRS received the documents successfully.

However, it is important to note that using an IRS fax number is not always the best option.

You may be unable to send some documents due to security concerns or the need for an original signature. In these cases, you should explore alternative methods to submit your documents.

To find all IRS fax numbers for specific purposes, visit the IRS website or contact them directly for assistance.

Why would you need to locate an IRS fax number?

Here are the main reasons to get ahold of specific IRS fax numbers:

  • You need to know the IRS fax number in order to submit documents to the government. For example, you might need to send in a tax return or other forms or documents related to your taxes.
  • You can use the IRS fax number to request transcripts of your tax-related documents or to provide financial information to a lender or other organization.
  • If you disagree with a review or audit the IRS has conducted on you, you can use the IRS tax fax numbers to send in your intention to dispute their findings. You’ll include supporting documents or evidence that shows why you think their assessment is incorrect.

A list of IRS fax numbers

We have compiled a list of IRS fax numbers for the most common tax forms and departments in order to help you simplify your tax filing process.

IRS Form 8806

Revamping your business through a merger or acquisition can bring exciting changes, but only if you have the essential paperwork filed correctly.

This form is only required if the reorganization meets specific criteria and the parties involved elect to treat the transaction as tax-free.
