IRS Fax Numbers: How and Where to Fax an IRS Tax Form?

Which Documents Can You Fax to the IRS?
Not all documents are accepted via fax. Generally, forms that do not require an original signature (or can be signed electronically) may be faxed to the IRS. One frequent question: there is no IRS fax number for Form 1040, since individual tax returns must be filed electronically or by mail. Here's a quick overview of which common IRS forms can and can't be faxed:
Forms You Can Fax
Form 2553: This form can be faxed to the IRS. It is used by businesses to elect S corporation status.
Form SS-4: This form, used to apply for an Employer Identification Number (EIN), can also be faxed.
Form 2848: This form authorizes an individual to represent you before the IRS and can be faxed as well.
Form 8821: This form allows the IRS to disclose your tax information to a third party and can be faxed as well.

Forms You Cannot Fax
Form 1040: This is the individual income tax return form and cannot be faxed. It must be filed either by mail or electronically
Form 433: This form, used for collection information statements, is typically not mentioned as eligible for fax submission, so it’s advisable to check directly with the IRS or consult a tax professional for guidance.
Form 4868: Known as the Application for Automatic Extension of Time to File U.S. Individual Income Tax Return, this form allows taxpayers to request extra time to submit their returns. It must be filed electronically or by mail—fax submissions are not accepted.
Form 8962: This form is used to calculate and reconcile the Premium Tax Credit, ensuring that any advance payments received are aligned with the actual credit due. It should be filed along with your tax return and is not suitable for fax submission.
Form 8809: The Application for Extension of Time to File Information Returns is designed for requesting additional time to file various information returns. As with other IRS forms, faxing is not an accepted method; it should be submitted electronically or by mail.
Form 8822: This form notifies the IRS of a change in your mailing address, ensuring that you receive all correspondence. It must be submitted by mail rather than fax.
Form 8850: Used by employers to pre-screen and certify potential employees for the Work Opportunity Tax Credit, this form must be filed following IRS guidelines. Fax submission is not permitted; filing should be done electronically or by mail.
Form 941: The Employer’s Quarterly Federal Tax Return reports income taxes withheld, as well as Social Security and Medicare taxes. This form is required to be filed by mail or electronically, and it cannot be faxed.
Form 1120: This is the U.S. Corporation Income Tax Return that corporations use to report their financial activities, including income, deductions, and tax liability. It must be filed either electronically or by mail—fax submission is not accepted.
If you frequently deal with overseas partners or clients, an international fax number could be more suitable. If your business operations are primarily local, a local fax number may suffice.
How to Send an IRS Form by Fax?
When it comes to requesting certain tax forms and documents from the Internal Revenue Service agency, you can order such documents from the IRS through fax by getting a local fax number (or port your currently existing fax number) and add the ability to receive faxes in Fax.Plus.
All your submitted documents will be accessible for future references in your fully encrypted Faxes tab and you can add notes and comments to each fax as well (If you wish you can also configure the service to not store your documents). Let’s see how you can send your tax documents as well your financial statements via the Fax.Plus secure faxing solution.
Add Fax Number
Go to the Send Fax section and enter the recipient’s fax number in the To field (country code + area code + fax number). You can send fax online from computer to multiple fax numbers at once.
Attach Fax Documents
Attach the documents you wish to fax. You can also add an optional fax cover sheet to you faxes and add some details about the recipient.
Send Fax to IRS
Send your fax and wait for the confirmation report. You will receive the report in your email, via push notification within Fax.Plus mobile app and can also be viewed in your Web dashboard.
How Long Does the IRS Take to Process a Faxed Form?
Processing time depends on the form, not on how fast your fax was delivered.
Form SS-4 (EIN)
Form 2848 & Form 8821
Form 2553 (S Corp Election)
Form 3911 (Refund Trace)
These are typical ranges, not guarantees. The IRS can take longer during peak filing season. Keep your Fax.Plus delivery confirmation as proof of when you sent the fax, in case you need to follow up.
Benefits of using Fax.Plus for faxing tax forms
Tax forms carry sensitive information like your SSN or EIN, so Fax.Plus encrypts every fax in transit. One of the major benefits of using Fax.Plus for IRS and tax forms is that you can print your successful fax transmission confirmation page for future reference. This confirmation page is always available in your Faxes tab and is also emailed to you right after your fax is delivered. If you want to receive responses from the IRS by fax as well, a paid Fax.Plus plan gets you a local fax number to do that.
Frequently Asked Questions
What is an IRS fax number?
An IRS fax number is a dedicated line that lets you send certain forms and documents straight to a specific IRS office instead of mailing them. There's no single number for the whole agency: each form gets its own number, and several route by the state you're filing from. Use the lookup tool at the top of this page, or check your form's instructions, then confirm the number on IRS.gov before sending, since numbers do change.
How do I know if an IRS fax number I found online is still valid?
Cross-check it against the number printed on your current IRS notice, the instructions for your specific form on IRS.gov, or our lookup tool above, which links out to the relevant IRS source page. IRS fax numbers change periodically without much public notice, so don't rely on a number from an old form revision or a search result alone.
What should I include on my IRS fax cover sheet?
Include your full name, your SSN or EIN, the exact form number and tax year, the total page count including the cover sheet itself, a phone number and email where you can be reached, and a one-line description of what you're sending. Missing or incomplete cover sheet details are one of the most common reasons a faxed form gets delayed or set aside for follow-up.
What common mistakes should I avoid when faxing the IRS?
Double-check you have the correct fax number, since sending to the wrong one is the top mistake. Make sure your document is legible, not faint or blurry, and that no pages or signatures are missing, since incomplete submissions are often rejected. Keep your delivery confirmation in case the IRS claims they never received your fax. And confirm your form is fax-eligible first: some forms, like Form 1040, are rarely accepted this way.
Can I upload documents to the IRS instead of faxing them?
For some notices, yes. The IRS Document Upload Tool accepts responses to specific notices that include a QR code or upload link. It doesn't replace fax for most forms discussed here, like Form SS-4 or Form 2553, which still require faxing or mailing. Check your notice for an upload option before defaulting to fax.
Can I use a digital signature on a form I fax to the IRS?
Not on every form. Form 2848 (Power of Attorney) and Form 8821 (Tax Information Authorization) require a wet ink, handwritten signature when submitted by fax or mail. Electronic or digital signatures aren't accepted for these two forms through this channel. Check your specific form's instructions before signing.
Can I fax IRS forms from my phone?
Yes. Download the Fax.Plus app, sign in or create a free account, then open Send Fax and enter the recipient's number. Attach a file, or use your phone's camera to scan a paper document right in the app, add a cover page if you like, and tap Send. You'll get a push notification once your fax is delivered.
Can I send a fax to the IRS through Gmail, Outlook, or Yahoo?
Yes, using Fax.Plus's email-to-fax feature. Attach your document to an email addressed in the format Fax.Plus provides for the recipient's fax number, then send it like any other email. Fax.Plus converts and delivers it as a real fax, so you don't need the app or web dashboard to send it.
Does the IRS confirm receipt of a faxed document?
Generally, no. The IRS doesn't send a separate confirmation once your fax arrives. Keep your Fax.Plus delivery confirmation, which shows the exact time your fax was successfully transmitted, as your proof of submission if the IRS later asks whether or when you sent something.
How long does it take the IRS to process a faxed form?
It depends on the form. Form SS-4 (EIN) requests are typically processed within a few business days. Form 2848 and Form 8821 usually take 3 to 5 business days. Form 2553 determinations can take up to 60 days. These are typical ranges; peak season can extend them. Your delivery confirmation only proves you sent it, not that the IRS has finished processing.
How can I request a copy of my tax return via fax?
Use Form 4506 to request a full copy of a past return, or Form 4506-T to request a free transcript instead. Both can be faxed to the appropriate IRS office. There's a fee for a full copy via Form 4506; transcripts requested with Form 4506-T are typically free.
Can I fax my amended tax return?
Yes, using Form 1040-X, and it must follow IRS guidelines for amended returns. Faxing acceptance can vary by situation, so check the instructions that came with your specific notice or consult the current Form 1040-X instructions before sending, especially if you're responding to a specific IRS letter.
What should I do if I need to send documents to the IRS urgently?
Faxing is one of the fastest options, since it delivers in seconds versus weeks by mail. Send it, save your Fax.Plus delivery confirmation immediately, and follow up by phone to confirm receipt, especially for time-sensitive notices where processing can still take several business days on the IRS side.
