The IRS is closed on Sundays and does not answer phones, process mail, or conduct business on that day
The Internal Revenue Service operates Monday through Friday, 7 a.m. to 7 p.m. in your local time zone. Sunday is a non-business day — no phone lines are staffed, no mail is processed, and no walk-in services are available at any IRS office. If you call the IRS on Sunday, you will reach an automated system that directs you to call back during business hours.
Saturday is also closed. The IRS does not operate on weekends at all. This applies to all IRS phone lines, local offices, and the Taxpayer Assistance Centers where you can meet with an agent in person.
Key Takeaways
- The IRS is closed every Sunday and does not answer phones or process documents on that day.
- Business hours are Monday through Friday, 7 a.m. to 7 p.m. in your local time zone, but call volume is heaviest early in the week and during tax season.
- You can mail documents to the IRS on any day, but mail sent on Sunday will not be processed until Monday.
- The IRS website and online tools like the Where's My Refund tracker work 24 hours a day, seven days a week, including Sundays.
How to reach the IRS when offices are closed
If you need to contact the IRS on a Sunday, you have limited options. The main IRS phone line (800-829-1040) will not connect you to a live agent. Instead, you will hear an automated message telling you to call back Monday through Friday during business hours. You can leave a callback request, but the IRS will not return your call until the next business day.
The IRS website remains open 24 hours a day. You can check the status of a refund using the Where's My Refund tool, view your tax account, or download forms and publications. You can also create or access your IRS online account to see payment history, tax records, and correspondence. These tools do not require speaking to anyone and work on Sunday just as they do on any other day.
What you can do on Sunday instead of calling
If you have a tax question or need to report something to the IRS, Sunday is a good time to prepare your documents and information so you are ready to call first thing Monday morning. Gather your tax return, any notices you received, your Social Security number, and details about what you need to report or ask about.
You can also mail documents to the IRS on Sunday. Put your envelope in the mail, and it will be picked up and delivered to the IRS processing center. The mail will not be processed until Monday or later, depending on postal delivery times, but mailing on Sunday does not delay your submission — the postmark date is what matters, not the day you drop it in the mailbox.
IRS phone lines are busiest early in the week
Even though the IRS is open Monday through Friday, not all times are equally good for calling. The phone lines are heaviest on Mondays and Tuesdays, especially in the morning. If you can call on a Thursday or Friday afternoon, you are more likely to reach someone without a long wait.
During tax season (January through April), all days are busy. If your question is not urgent, waiting until May or later will mean shorter hold times. Outside of tax season, you may reach someone within 15 to 30 minutes. During tax season, waits can exceed an hour.
Walk-in services at IRS offices
If you prefer to meet with someone in person, the IRS operates Taxpayer Assistance Centers in most cities. These offices are open Monday through Friday only, with hours typically from 9 a.m. to 4 p.m., though some locations have extended hours. You can find the nearest office and its hours on the IRS website by entering your zip code.
Walk-in service is available, but arriving early is important because offices close when they reach capacity. During tax season, arriving before 9 a.m. gives you the best chance of being seen the same day. Outside of tax season, you can usually walk in and wait 30 minutes to an hour.
Holidays when the IRS is also closed
Beyond Sundays and Saturdays, the IRS is closed on federal holidays. These include New Year's Day, Martin Luther King Jr. Day, Presidents' Day, Memorial Day, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving, and Christmas. On these days, phone lines are not staffed and offices are not open, even if the day falls on a weekday.
If a federal holiday falls on a Friday, the IRS is closed that Friday. If it falls on a Monday, the IRS is closed that Monday. If you mail a document on a holiday, it will not be processed until the next business day.
Frequently Asked Questions
Can I mail something to the IRS on Sunday?
Yes. You can place mail in a mailbox on Sunday, and the postal service will pick it up and deliver it to the IRS. The IRS will not process it until Monday or later, but the postmark date is what counts for filing deadlines, not the day you mailed it.
What if I have an urgent tax problem on Sunday?
If your situation is truly urgent — for example, you are being audited and your deadline is Monday — call the IRS first thing Monday morning. If you cannot reach them by phone, visit a Taxpayer Assistance Center in person. For emergencies involving wage garnishment or bank levies, you may also contact a tax professional or attorney who can represent you.
Does the IRS process tax returns on Sunday?
No. The IRS does not process returns, refunds, or payments on Sunday. If you file electronically on Sunday, your return is received and queued, but processing does not begin until Monday. Mailed returns are not processed on Sunday either.
Can I check my refund status on Sunday?
Yes. The Where's My Refund tool on the IRS website works 24 hours a day, seven days a week. You can check the status of your refund on Sunday anytime. The information updates once per day, usually overnight, so checking on Sunday evening may show the same status as Saturday.
What time should I call the IRS on Monday morning?
The IRS phone lines open at 7 a.m. in your local time zone. Calling at 7 a.m. or shortly after gives you the shortest wait, though lines are still busy. If you can call after 4 p.m., waits are often shorter, but the lines close at 7 p.m.
