The IRS has three main ways to reach a person: by phone during tax season, by mail year-round, or by visiting a local office

The IRS phone line is 1-800-829-1040 for individual tax questions. This number works best between January and April, when staffing is highest and wait times are shortest — often 15 to 45 minutes. Outside tax season, you may wait several hours or reach an automated system that cannot solve your problem. The line is open Monday through Friday, 7 a.m. to 7 p.m. in your local time zone.

If you cannot reach someone by phone or prefer not to wait, you can mail a letter to the IRS service center that handles your state. Mail takes 4 to 8 weeks for a response. You can also walk into a local IRS office without an appointment, though wait times vary widely and some offices have reduced hours. The IRS website has a locator tool at irs.gov that shows the nearest office and its current hours.

The method you choose depends on how urgent your question is and what you need to discuss. Tax account issues, payment problems, and notices usually require speaking to someone who can access your file. General questions about forms or deadlines can sometimes be answered by the automated system or a website search.

Key Takeaways

  • Call 1-800-829-1040 Monday through Friday, 7 a.m. to 7 p.m. your local time; wait times are shortest in January through March.
  • Mail works year-round but takes 4 to 8 weeks; send your letter to the service center for your state, which you can find on irs.gov.
  • Walk-in visits to a local IRS office do not require an appointment, but hours vary by location and some offices have limited availability.
  • Have your Social Security number, tax year in question, and any relevant documents ready before you call or visit.

When to call versus when to mail

Call the IRS if you need an answer within days or if your question involves your specific tax account. This includes questions about a refund status, a notice you received, a payment you made, or a change to your return. The phone line can also help if you are unsure whether you need to file or what forms to use. Calls work best during tax season (January through April) when the IRS has more staff available.

Mail the IRS if you have time to wait or if your question is complex and requires documentation. Mail is also the right choice if you have tried calling multiple times without success, or if you need a written record of your question and the IRS response. Always send mail to the service center for your state — sending it to the main IRS office in Washington, D.C. will delay it. The irs.gov website lists the correct address for each state.

What to have ready before you call

Gather these items before you dial: your Social Security number or Individual Taxpayer Identification Number (ITIN), the tax year you are calling about, and any notice or letter the IRS sent you. If you are calling about a payment, have the check or payment confirmation number. If you are calling about a refund, have your filing status and the amount you expected to receive. If someone else is calling on your behalf, you will need to authorize them — the IRS may ask security questions to verify your identity first.

Write down your questions before you call so you do not forget them during the wait. Keep your questions specific: instead of "Why is my refund late?" try "I filed my 2023 return on February 15 and have not received my refund — can you tell me the status?" Specific questions are faster to answer and less likely to be transferred to another department.

How to find your local IRS office

Go to irs.gov and use the "Office Locator" tool to find the IRS office nearest you. Enter your ZIP code and the tool will show you the address, phone number, and hours of operation. Some offices are open Monday through Friday only; others have limited hours or are closed certain days. Call ahead or check the website before you visit, because hours change seasonally and some offices have reduced staff.

Walk-in visits do not require an appointment, but you may wait 30 minutes to two hours depending on how busy the office is. Bring the same documents you would have ready for a phone call: your Social Security number, the tax year in question, any IRS notice, and proof of identity. Some offices are busier on certain days — calling ahead can tell you when to expect the shortest wait.

Mailing a letter to the IRS

Write a clear, one-page letter explaining your question or issue. Include your name, Social Security number, the tax year in question, and a daytime phone number where the IRS can reach you. Attach copies (not originals) of any documents that support your question — a notice from the IRS, a cancelled check, a bank statement, or a copy of your return. Do not send original documents; the IRS will not return them.

Mail your letter to the service center for your state. The IRS website lists the correct mailing address for each state under "Where to File." Use certified mail with return receipt if your question involves a deadline or a dispute — this gives you proof the IRS received it. Standard mail takes 4 to 8 weeks for a response. If you do not hear back within 8 weeks, call 1-800-829-1040 and reference your certified mail receipt number.

What to do if you cannot reach anyone

If you have called multiple times and cannot reach a person, try calling early in the morning (7 a.m. to 8 a.m. your local time) or late in the day (after 5 p.m.). These times often have shorter waits. You can also try calling on a Tuesday, Wednesday, or Thursday — Mondays and Fridays tend to be busier. If you are calling outside tax season (May through December), expect longer waits; consider mailing your question instead.

If your question involves a deadline — such as a response date on an IRS notice — mail your letter immediately so you have proof of the date you sent it. The IRS counts the postmark date, not the date they receive it. If you have a tax professional (an accountant, enrolled agent, or tax attorney), they may be able to reach the IRS faster by using their own credentials and a dedicated line for representatives.

Frequently Asked Questions

Can I schedule a phone appointment with the IRS instead of waiting in the queue?

The IRS does not offer scheduled phone appointments for most tax questions. You call and wait in the queue. However, if you have a complex issue or a deadline, you can request a callback by calling 1-800-829-1040 and asking the automated system to add you to the callback list. The IRS will call you back within 24 hours, though this is not may provide during peak season.

What if I need to speak to someone about an audit or a dispute?

Audit and dispute cases are handled by different departments. Call 1-800-829-1040 and tell the representative you need the Examination or Appeals division. You may be transferred or given a separate phone number. If you have received an audit notice, the notice itself includes a phone number and contact information for your assigned agent.

Can I email the IRS instead of calling or mailing?

The IRS does not have a general email address for tax questions. Some local IRS offices accept email for specific issues — check the office locator on irs.gov to see if your local office lists an email. For most questions, phone or mail is the only option.

How long will I wait on hold if I call during tax season?

Wait times vary widely depending on the day and time you call. During peak tax season (February through April), waits can range from 15 minutes to over two hours. Calling early in the morning or mid-week usually results in shorter waits than calling in the afternoon or on Mondays and Fridays.

What if I do not have a Social Security number?

If you have an Individual Taxpayer Identification Number (ITIN) instead, use that. If you do not have either, you may still be able to reach the IRS, but you will need to provide other identifying information such as your date of birth and filing status. Call 1-800-829-1040 and explain your situation to the representative.
