The IRS main customer service number is 1-800-829-1040

The Internal Revenue Service (IRS) main phone line is 1-800-829-1040. This number connects you to general tax questions, account information, and payment issues. Wait times are longest during tax season (January through April), so calling early in the morning or later in the afternoon often means shorter holds.

The IRS operates this line Monday through Friday, 7 a.m. to 7 p.m. in your local time zone. The system uses automated menus to route your call—listen carefully to the options, as selecting the right category the first time can save you from being transferred multiple times.

If you are calling about a specific notice the IRS sent you, have that notice in front of you. The notice includes a phone number and a case number, and calling that specific line often gets you to someone who already has your file open.

Specialized IRS phone numbers for different situations

The IRS maintains separate phone lines depending on what you need. If you own a business or file business taxes, call 1-800-829-4933. This line handles Schedule C, partnership returns, S-corporation questions, and other business-related tax matters. The hours are the same as the main line.

Tax professionals and enrolled agents use 1-866-860-4259. This line is for people who represent taxpayers before the IRS—if you have a CPA or tax attorney handling your case, they would call this number on your behalf.

If you are deaf, hard of hearing, or have a speech disability, the IRS TTY line is 1-800-829-4059. This line uses text telephone technology and operates during the same hours as the main line.

What information to have ready before you call

Gathering documents before you dial saves time on hold and helps the IRS representative answer your question faster. Have your Social Security number or Individual Taxpayer Identification Number (ITIN) ready, along with your filing status and the tax year you are calling about.

If you are calling about a payment, know the amount you paid and the date you paid it. If the IRS sent you a notice, have that notice in front of you—it contains your case number and often a dedicated phone line. If you are calling about a refund, have your return confirmation number, which appears on your tax return or in your IRS account.

Write down your questions before calling so you do not forget anything while on hold. The IRS representative can usually answer multiple questions in one call if you have them organized.

Using IRS.gov instead of calling

The IRS website at irs.gov offers several ways to get answers without waiting on the phone. The site includes a search function where you can type your question—many common issues have answers in the IRS knowledge base. You can also use the IRS's online chat feature during business hours, which often has shorter wait times than the phone line.

If you want to speak to someone but do not want to hold, you can request a callback through irs.gov. Enter your phone number and preferred callback time, and an IRS representative will call you back during that window. This feature is especially useful if you are calling during tax season when hold times exceed an hour.

You can also check the status of your refund, view your tax account, and make payments through your IRS online account at irs.gov. Creating an account takes about 10 minutes and lets you handle many issues without calling at all.

Why you might not reach a person when ready

The IRS receives millions of calls each year, and during tax season the volume far exceeds the number of representatives available. From January through April, wait times regularly exceed 30 minutes, and some callers are disconnected after waiting more than an hour. This is not a sign that your call is not important—it is straightforward a volume problem.

The IRS also closes phone lines for system maintenance on certain days. If you get a message that the line is temporarily closed, try again the next business day. The IRS website announces these closures in advance, so checking irs.gov before calling can tell you whether the line is operating.

What the IRS phone line can and cannot do

The IRS phone line can answer questions about tax law, help you understand a notice, provide information about payment plans, and direct you to forms and publications. Representatives can look up your account information and tell you the status of your refund or payment.

The phone line cannot process a new return, amend a return you already filed, or make changes to your account directly during the call. For those tasks, you will need to mail documents, use your online IRS account, or work with a tax professional. The representative can tell you which method is fastest for your situation.

Frequently Asked Questions

How long will I wait on hold when I call the IRS?

Wait times vary by season and time of day. During tax season (January through April), expect 30 minutes to over an hour. Outside tax season, morning calls often connect within 10 to 20 minutes. Calling on Tuesday, Wednesday, or Thursday typically means shorter waits than Monday or Friday.

Can I schedule an in-person appointment at an IRS office instead of calling?

Yes. Visit irs.gov and search for "IRS offices near me" to find your local Taxpayer information Center. You can schedule an appointment online or by phone. In-person appointments are useful for complex issues or if you prefer to speak face-to-face, though wait times for appointments can be several weeks during tax season.

What if I call and get disconnected?

Call back and try again. The IRS does not have a callback list for disconnected calls, so you will need to dial the number again. If you keep getting disconnected, try the callback request feature on irs.gov instead, which guarantees a call back during your preferred time window.

Is there an IRS phone number for people outside the United States?

Yes. If you are calling from outside the U.S., call 267-941-1000. This is a long-distance call and may incur international charges depending on your phone plan. You can also mail questions to the IRS address listed on your tax return or notice.

Can I leave a voicemail for the IRS to call me back?

No. The IRS phone system does not accept voicemails. You must stay on the line until you reach a representative or use the callback request feature on irs.gov. If you hang up, you will need to call again.
