IRS phone lines open at 7 a.m. Eastern time, Monday through Friday

The IRS operates a toll-free phone line during business hours. Calls are taken starting at 7 a.m. ET and ending at 7 p.m. ET, Monday through Friday. The main number is 1-800-829-1040. Wait times are typically shortest early in the morning, especially before 10 a.m.

The IRS does not answer phones on weekends or federal holidays. If you call on a holiday, you will reach an automated system that can direct you to online resources or tell you when lines will reopen. The agency also closes for certain observances — check the IRS website for the current year's holiday schedule if you are calling near a federal holiday.

Different IRS departments have different phone numbers and hours. If you are calling about a specific issue — tax transcripts, payment plans, or a notice you received — the IRS website lists dedicated numbers for each topic. Using the right number saves you from being transferred multiple times.

What to expect when you call during business hours

When you reach the IRS, you will hear an automated menu. You select your issue using the keypad — for example, pressing 1 for questions about a tax return, 2 for payment issues, or 3 for a notice. This routing system can take a few minutes. After you select your category, you enter a queue to speak with a representative.

Hold times vary widely depending on the time of year and time of day. During tax season (January through April), waits of 45 minutes to over an hour are common. Outside tax season, waits are often 15 to 30 minutes. If you are on hold for more than a few minutes, the system will offer to call you back instead of keeping you on the line — this option can save you from paying for a long hold.

Have your Social Security number, tax return, or the notice you received ready before you call. The representative will ask for this information to pull up your account. If you do not have these items, the call may take longer or the representative may not be able to help you immediately.

Specialized phone lines and their hours

The IRS operates separate phone lines for specific needs. The line for tax transcripts and account information (1-800-908-9946) opens at 7 a.m. ET and closes at 7 p.m. ET. The line for payment plans and installment agreements (1-800-829-7650) has the same hours. The line for business tax matters (1-800-829-4933) also opens at 7 a.m. ET.

If you received a notice from the IRS, that notice usually includes a phone number specific to your case. Calling the number on the notice is faster than calling the general line, because the representative can see your case details immediately. These specialized lines may have different hours than the main number, so check the notice before you call.

The IRS also operates a line for tax professionals and representatives (1-866-860-4259). If you have a power of attorney or tax professional handling your case, they can call this line instead of the general number. Hours are 7 a.m. to 7 p.m. ET, Monday through Friday.

Online and mail options when phone lines are closed

If you cannot reach the IRS by phone, you can create an account on IRS.gov and view your account information, check the status of a refund, or make a payment. The website is open 24 hours a day. You can also download tax forms, transcripts, and notices from the website without calling.

For questions that are not urgent, you can mail a letter to the IRS. The address depends on your state and the type of question — the IRS website lists the correct mailing address for your situation. Mail typically takes 4 to 6 weeks to reach the IRS and another 4 to 6 weeks for a response, so this option is not useful if you need an answer quickly.

The IRS also offers in-person help at local IRS offices in some cities. You can schedule an appointment through the IRS website. Hours vary by location, and many offices are open only a few days per week. Appointments are often booked weeks in advance during tax season.

What to do if you cannot reach anyone

If you have called multiple times and cannot reach a representative, the IRS Taxpayer Advocate Service may be able to help. This is a free service within the IRS that assists people who have had trouble getting through or resolving their issue through normal channels. You can request help by calling 1-877-777-4778 or by filling out a form on the IRS website.

The Taxpayer Advocate Service does not answer phones immediately — you will likely leave a message and receive a call back within a few business days. This service is useful if you have a deadline (such as a court date or a notice response deadline) and the regular phone line is not helping you meet it.

If you are working with a tax professional or attorney, they may have faster access to IRS staff through their own channels. Some tax firms have direct lines to IRS representatives, though this is not common for routine questions.

Frequently Asked Questions

Can I call the IRS before 7 a.m. or after 7 p.m.?

No. The main IRS phone line does not answer calls outside 7 a.m. to 7 p.m. ET. If you call outside these hours, you will reach an automated system that can direct you to the website or tell you when lines reopen. Some specialized lines may have different hours — check the number on your notice or the IRS website.

What if I call on a Saturday or Sunday?

The IRS does not answer phones on weekends. You will reach an automated system. Use the IRS website to check your account, download forms, or find the address to mail a question. You can also call back on Monday morning.

Is there a shorter wait time at certain times of day?

Yes. Calls before 10 a.m. and after 5 p.m. typically have shorter waits than midday calls. Early morning (7 a.m. to 9 a.m.) is usually the fastest time to reach someone. During tax season, even early morning calls can involve 20 to 30 minute waits.

Can I schedule a callback instead of waiting on hold?

Yes. When you are in the queue, the automated system will offer to call you back at a time you choose. This saves you from sitting on hold, though the callback may come during a different time window than you requested.

What if the IRS number is busy and I cannot get through?

Try calling again in 15 to 30 minutes, or try the next day. During tax season, the lines are busiest between 10 a.m. and 4 p.m. Calling early morning or late afternoon usually results in shorter waits. You can also use the IRS website to handle many issues without calling.
