IRS Business Hours: Phone Lines, Offices, and 2026 Holidays

IRS business hours are Monday through Friday, 7:00 a.m. to 7:00 p.m. local time on every phone line the agency runs for individuals, businesses, and tax professionals. Taxpayer Assistance Centers keep shorter weekday hours of 8:30 a.m. to 4:30 p.m. by appointment only, and most tools on IRS.gov stay available around the clock apart from short maintenance windows.¹

Phone Hours by Line

The main number for individual tax questions is 800-829-1040. Representatives handle return questions, refund inquiries, notice explanations, payment options, and account adjustments, weekdays from 7:00 a.m. to 7:00 p.m. local time.¹

Business callers use 800-829-4933 for Employer Identification Numbers, corporate and partnership returns, federal tax deposits, excise taxes, and estate and gift tax returns. Same weekday window: 7:00 a.m. to 7:00 p.m. local time.²

Other lines keep the same weekday hours unless noted:

TTY/TDD for deaf and hard-of-hearing callers: 800-829-4059, 7:00 a.m. to 7:00 p.m.³
Identity Protection PIN assistance: 800-908-4490, 7:00 a.m. to 7:00 p.m.⁴
Practitioner Priority Service (tax professionals only): 866-860-4259, 7:00 a.m. to 7:00 p.m.⁵
Taxpayer Advocate Service: 877-777-4778, weekdays, with generally shorter waits than the main lines.
International Taxpayer Service Call Center (not toll-free): 267-941-1000, 6:00 a.m. to 11:00 p.m. Eastern.⁶
Automated refund hotline: 800-829-1954, 24 hours. Joint filers cannot start a refund trace here and must call 800-829-1040 instead.⁷

Time Zone Exceptions

Alaska and Hawaii callers follow Pacific time rather than their own local clock. Puerto Rico callers reach the same lines from 8:00 a.m. to 8:00 p.m. local time.¹

Best Times to Call

Hold times climb sharply from late January through mid-April. Calling right at 7:00 a.m. or after 6:00 p.m. usually gets you through faster. When the system estimates a wait over about 15 minutes, it offers a callback: you hang up and receive a return call without losing your place in line. Have your Social Security number, any notices you received, and a copy of your most recent return in front of you before dialing.

Language Assistance

For Spanish, dial 800-829-1040 and the system routes you to a bilingual representative or connects an interpreter. For other languages, an IRS assistor can bring a professional interpreter onto the call at no charge.¹

In-Person Office Hours

IRS Taxpayer Assistance Centers operate Monday through Friday, 8:30 a.m. to 4:30 p.m. local time. Every visit requires an appointment, and walk-ins are turned away. Book by calling 844-545-5640; the representative first checks whether your issue actually needs an in-person visit before scheduling.³⁸

Saturday Hours in 2026

During filing season, many TACs open on select Saturdays from 9:00 a.m. to 4:00 p.m. The 2026 dates are:

February 28
March 28
April 11
April 25
May 30
June 27

All regular TAC services are available on these Saturdays except cash payments. Not every office participates, so check your local TAC’s listing on IRS.gov before making the trip.³

Online Tools and Maintenance Windows

IRS.gov is the fastest channel for most routine tasks. Where’s My Refund tracks return processing, the Online Account portal shows balances and payment history, the Interactive Tax Assistant answers common tax-law questions, and Direct Pay handles bank-account payments at no fee.⁸

These tools run almost continuously, with short scheduled downtime:

Where’s My Refund is unavailable every Monday from midnight to 3:00 a.m. Eastern. The Refund Trace feature has additional downtime on Sundays from midnight to 7:00 p.m. Eastern and brief early-morning windows most other days.⁹
Direct Pay is unavailable nightly from 11:45 p.m. to midnight Eastern.¹⁰
E-Services for tax professionals is unavailable Sundays from midnight to 4:00 p.m. Eastern.¹¹
EFTPS runs 24/7 and accepts scheduled payments up to 365 days in advance.¹²

Tax forms and publications remain downloadable at any hour regardless of maintenance schedules.
