IRS Business Phone Number | Contact IRS Customer Service

IRS Business Phone Number puts you through to the IRS office or its other agencies during Customer Support hours. If you have the number on your phone, you can either schedule a visit or finish up on a phone call.


Sometimes, people do not know what to say or how to put the words across. However, practitioners can get you through this strait, helping you with the requirements and crucial details for contacting the IRS office. Without these prelims, you may not get the results you want eventually.

Contacting the IRS requires a few preps and criteria, since the online support, live chat, and other CS links are not always accessible to users. So, it is better to use any opportunity wisely than to botch a scheduled in-person visit because of a lack of preparation.

How Do I Contact the Customer Service?

If you have a business that likely involves taxes, tax payments, verifying tax status, tracking tax status, or retrieving a relevant detail from the IRS directory, then you may need to contact Customer Service.

Although this may not happen often, it comes off as quite helpful for you to have the hotline just in case you need it.

Specifically, the IRS Business Phone Number that puts you through to an agent is 800-829-4933. Once you dial the number, you can wait a few minutes for the connection, after which you can narrate the complaint.

Usually, Customer Service is available for 12 hours, best in the period between 7 a.m. and 7 p.m. Any other attempts to reach the CS outside this bracket are going to be stressful. That is when you might expect high traffic, even if there is increased activity at the CS terminal.

The best time to call the CS is sometime in the middle of the week, sometime between Tuesday and Thursday, and usually around 10 a.m. In case you have a lot to discuss, ensure that your calls are placed well before the 7 p.m. mark, otherwise you will experience a long holdup.

Further, you have to ensure that you have sufficient reasons for dialing the IRS Business Phone Number. As it happens, the official Chat CS support will only tend to calls about issues that have not been covered on the site.

So, before you get started with the IRS Business Phone Number or an email link, check the website for an FAQ that could be of help.

IRS Business Phone Number | When You Should Call the IRS

As we explained in the previous section, the IRS doesn’t attend to random calls, especially issues that have already been addressed on the site. With the IRS Business Phone Number, the caller is expected to forward other complaints apart from the ones on the site.

To help you with this, the IRS already has a good FAQ and helpdesk directory on the website, which provides suitable fixes, resolutions, or suggestions about typical complaints raised by customers.

Here is an outline of the issues that are better referenced on

Forms & Transcripts — Do not dial the IRS Business Phone Number to request forms for any of the services offered either on the site or at any outlet.

Further Clarification — if you have any doubts about a detail on the site, consider asking a professional for assistance. In any case, the explanations are simple and complete. So, you will have no problems understanding them. Even the technical aspects are largely left out, allowing users to seek immediate help on the site.

Also, don’t call the IRS Business Phone Number to discuss taxes, tax advisories, or to verify applicable laws regarding tax topics already covered sufficiently on the site.

In some cases, the IRS Business Phone Number won’t be suitable for tracking Refund Status, especially for complaints that aren’t at least 21 days since first contact.


It is preferable to keep track of a Refund Status using the IRSGo App (you can get this on Play Store or Apple Store).

IRS Business Phone Number | How to Prepare for the Call

You do not just set up an arbitrary call with the Internal Revenue Service. It doesn’t work that way. If you need to forward a complaint, ensure you have the specifics and supporting documents close.

Then get these details ready.

Ensure you have a Taxpayer Identity Number (TIN) or a social security card.

Also, you can get documents supporting your Date of Birth around when contacting the agency. Often, in cases involving payments and refunds, it is helpful that you bring recent proof of payments with you.

If you have set up prior contacts with the IRS, go along with details from these previous visits.

Lastly, indicate Filing Status.

Are you standing in for someone else?

Get authorization documents (usually in Form 2848) for a person you are representing; in case you are not the one lodging the complaint. Moreover, you must go with every relevant document of the person about the IRS complaint. If this is about payments, ensure that you go with Proofs and receipts.
