The IRS is open Monday through Friday, 7 a.m. to 7 p.m. in your local time zone

The Internal Revenue Service operates on standard business hours year-round. Most IRS offices and phone lines are staffed during these hours, though some services have different schedules. The IRS does not operate on weekends or federal holidays, and offices close on those days.

Phone lines are busiest in the morning and early afternoon. If you call after 5 p.m., you may reach a voicemail system instead of a live person. The IRS also offers online services through IRS.gov that you can access any time, including nights and weekends.

Key Takeaways

  • IRS phone lines and walk-in offices operate Monday through Friday, 7 a.m. to 7 p.m. in your local time zone, and are closed on weekends and federal holidays.
  • Call volume is heaviest in the morning, so afternoons often have shorter wait times.
  • Online services through IRS.gov, including account transcripts and payment options, are available 24 hours a day.
  • The IRS Individual Identification Number (ITIN) application process and certain forms can be submitted by mail or electronically outside business hours.

Phone lines and walk-in office hours

If you need to speak with an IRS representative by phone, call the main IRS line at 1-800-829-1040. This number connects you to the IRS Customer Service line, which operates Monday through Friday, 7 a.m. to 7 p.m. your local time. Wait times vary depending on the time of year and time of day you call.

Walk-in IRS offices are also open Monday through Friday during these same hours. You can find your nearest office on IRS.gov by using the office locator tool. Some offices require an appointment, so call ahead before visiting in person. Offices close on all federal holidays, including New Year's Day, Independence Day, Thanksgiving, and Christmas.

Seasonal closures and holiday schedules

The IRS closes on all federal holidays observed by the U.S. government. This includes New Year's Day, Martin Luther King Jr. Day, Presidents' Day, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving, and Christmas. When a holiday falls on a weekend, the IRS observes the closure on the nearest weekday.

Tax season (January through April) brings longer wait times and higher call volumes, but the IRS maintains the same 7 a.m. to 7 p.m. hours. If you need to reach the IRS during a holiday or after hours, you can use online services or mail your documents to the appropriate IRS address for your state.

Online services available 24 hours a day

You do not have to wait for business hours to access many IRS services. IRS.gov offers tools and resources available around the clock, including checking the status of a refund, viewing your tax account, downloading transcripts, and making a payment or setting up a payment plan. You can also create an IRS online account to manage your tax information.

The IRS also operates an automated phone system outside business hours. If you call 1-800-829-1040 after 7 p.m. or before 7 a.m., you can use the automated menu to check refund status, make a payment, or request forms and publications. This system is available 24 hours a day, seven days a week.

Different hours for specialized services

Some IRS services operate on different schedules than the main phone line. The Taxpayer Advocate Service, which helps resolve disputes and problems, operates Monday through Friday, 7 a.m. to 7 p.m. You can reach them at 1-877-777-4778. The IRS Criminal Investigation division does not have public phone hours; you must contact your local field office or submit information online.

If you are calling about a specific issue like a notice you received or a payment plan, the IRS may route you to a specialized department with its own wait times. The main line can direct you to the right department when you call.

Best times to call the IRS

Early morning calls, between 7 a.m. and 9 a.m., often have shorter wait times than midday calls. Calling on Tuesday, Wednesday, or Thursday typically results in faster connections than Monday or Friday. Avoid calling during tax season (January through April) if possible, as wait times can exceed an hour.

If you have a simple question, the automated phone system may be faster than waiting for a representative. For complex issues, calling in the afternoon after 3 p.m. sometimes has lower volume than the morning rush, though this varies by day and season.

Mailing documents when offices are closed

If you cannot reach the IRS by phone or need to submit documents outside business hours, you can mail your forms and supporting documents to the IRS. The address depends on your state and the type of form you are sending. IRS.gov lists the correct mailing address for each state and form type.

Mail typically takes one to two weeks to reach the IRS, and processing can take several weeks longer. If your matter is time-sensitive, calling during business hours or using online services is faster. Keep copies of everything you mail and consider using certified mail with return receipt to confirm delivery.
