The IRS has three main phone lines, and which one you call depends on what you need
The IRS operates separate phone lines for individual tax returns, business tax returns, and tax-exempt organizations. If you call the wrong line, you will be transferred or told to call back. The main individual line is 1-800-829-1040. The business line is 1-800-829-4933. Both lines are open Monday through Friday, 7 a.m. to 7 p.m. in your local time zone.
Wait times are longest in the morning and during tax season (January through April). Calling after 5 p.m. or on Thursday and Friday afternoons typically means shorter waits. The IRS does not staff these lines on weekends or federal holidays.
You will need your Social Security number or Individual Taxpayer Identification Number (ITIN), your filing status, and any documents related to your question before you call. Having these ready cuts your call time in half.
Key Takeaways
- The individual tax line is 1-800-829-1040; the business line is 1-800-829-4933; both operate Monday through Friday, 7 a.m. to 7 p.m. in your time zone.
- Wait times are shortest after 5 p.m. and on Thursday and Friday afternoons, and longest in the morning and during January through April.
- You can request a callback instead of waiting on hold, and the IRS will call you back within 24 hours during business hours.
- If you cannot reach the IRS by phone, you can visit a local IRS office in person, though appointments are required and must be scheduled online.
- The IRS also answers written questions by mail, but responses take 30 days or longer.
Request a callback instead of waiting on hold
When you call the IRS main line, the automated system will offer you the option to request a callback. Select this option if the wait time is longer than 30 minutes. The IRS will call you back within 24 hours during business hours, and you do not have to stay on the phone.
Write down the callback number the system gives you. If the IRS does not reach you at the scheduled time, you can call that number to reschedule. The callback system works on the same schedule as the phone lines: Monday through Friday, 7 a.m. to 7 p.m. in your time zone.
Visit an IRS office in person
Every state has at least one IRS office where you can walk in and speak to a representative. You cannot simply show up; you must schedule an appointment online at irs.gov or by calling 1-844-545-5640. The appointment line is open Monday through Friday, 7 a.m. to 7 p.m. in your time zone.
Appointments are usually available within one to two weeks. Bring your Social Security number, photo ID, and any documents related to your question. The office will not discuss your case without these items. Bring originals or certified copies, not photocopies, for tax returns or notices.
Send a written question by mail
You can mail a letter to the IRS with your question, and they will respond in writing. Address your letter to the IRS office that serves your state. You can find the correct address on irs.gov under "Contact Your Local IRS Office."
Include your name, address, Social Security number, phone number, and a clear description of your question. Attach copies (not originals) of any documents that support your question, such as a notice from the IRS or a copy of your tax return. Do not send original documents by mail.
Responses typically take 30 days or longer, depending on the complexity of your question and the current volume of mail the IRS is processing. This method is slower than calling or visiting in person, but it creates a written record of your question and the IRS's answer.
Use IRS.gov to find answers without calling
The IRS website has a searchable database of answers to common questions, organized by topic. You can search for your question directly on irs.gov, and many questions are answered within minutes. The site also has interactive tools for calculating tax liability, finding your refund status, and understanding tax credits.
If you know the IRS notice number or letter code you received, you can search for it on irs.gov to see what it means and what action you need to take. This is often faster than calling, because you get an answer immediately and do not have to wait on hold.
What to expect when you reach someone
When you speak to an IRS representative, they will ask you to verify your identity by providing your Social Security number and date of birth. They may also ask for information from your tax return, such as your filing status or the amount of a refund you received. This verification takes two to three minutes.
After verification, the representative will ask you to describe your question or issue. Be specific: instead of saying "I have a problem with my return," say "I received a notice saying I owe $500 in taxes from 2022, but I already paid that amount." The more specific you are, the faster the representative can help you.
The representative can answer questions about your account, explain notices you received, help you understand tax rules, and in some cases make changes to your account. They cannot make a judgment call about whether you owe taxes; that information is made by the IRS office that issued your notice. If you disagree with a notice, the representative will explain your right to appeal.

| Question about a payment or balance owed | The notice showing the balance, your tax return, and records of any payments you made |
| Question about tax credits or deductions | Your tax return, W-2 forms, 1099 forms, and receipts for expenses you claimed |
| Question about a business tax issue | Your business tax return, business records, and any notices from the IRS |
Frequently Asked Questions
How long will I wait on hold when I call the IRS?
Wait times vary from 15 minutes to over an hour, depending on the time of day and the time of year. The IRS publishes current wait times on irs.gov before you call. If the wait is longer than 30 minutes, use the callback option instead.
Can I speak to the same representative if I call back?
No. Each call is routed to the next available representative. If you need to follow up on a previous call, have the date and time of your first call ready, and the new representative can pull up your account history.
What if I disagree with what the IRS representative told me?
You can request a second opinion by calling back and asking to speak to a supervisor. You can also file a formal appeal if the IRS has issued you a notice. The notice will explain how to appeal and the deadline for doing so.
Does the IRS have a chat or email support option?
The IRS does not offer live chat or email support for individual questions. You can only reach them by phone, in person, or by mail. Some tax software companies offer chat support to help you prepare your return, but they cannot answer questions about your IRS account.
What if I need an interpreter?
Tell the automated system or the representative that you need an interpreter, and state the language. The IRS can provide interpretation services in most languages at no cost to you. Interpretation may add 10 to 15 minutes to your call.
