Official IRS Phone Numbers (Current for 2026)

The IRS provides separate lines based on the type of assistance required. Calling the correct department ensures faster service.

All listed numbers are toll-free within the United States.

IRS Phone Hours in 2026

Live phone assistance operates on the following schedule:

• Monday through Friday
• 7:00 a.m. to 7:00 p.m. local time

Services are closed on federal holidays.

Automated systems, including refund tracking, typically remain accessible outside standard operating hours.

Best Times to Call the IRS

Call volume increases during tax season, especially from late January through mid-April. Wait times vary depending on the time of year and day of the week.

For shorter hold times:

• Call right at 7:00 a.m.
• Avoid Mondays if possible
• Skip the day after a holiday
• Choose mid-week mornings

Preparation also reduces call duration and improves results.

What You Can Resolve by Phone

The IRS customer service number can help resolve many common issues, including:

• Questions about filed returns
• Missing refund concerns
• Balance due inquiries
• Installment agreements
• Identity verification requests
• Notice clarification
• Business tax compliance matters

Complex cases may still require written documentation or online submission.

Prepare Before You Call

Having the right information ready saves time and prevents repeated verification steps. Gather:

• Social Security number or ITIN
• Date of birth
• Filing status
• Copy of your most recent tax return
• IRS notice or letter number
• Bank information if discussing payments

Being organized helps representatives assist you efficiently.

Refund Questions in 2026

Before calling about your refund, check the online refund tracking tool. It updates once daily and often provides faster information than phone support.

If you choose to call the automated refund hotline, make sure the standard IRS processing timeframe has passed. Calling too early may not produce additional details.

Avoid IRS Phone Scams

Impersonation scams remain a concern. The IRS does not:

• Demand immediate payment by phone
• Threaten arrest or deportation
• Request payment through gift cards or prepaid debit cards

If you receive a suspicious call claiming to be from the IRS, hang up and dial one of the verified numbers above directly.

Never return calls to unknown numbers claiming to represent the agency.

Digital Alternatives to Calling

The IRS continues expanding online tools that allow taxpayers to:

• View account balances
• Make payments
• Set up installment agreements
• Access transcripts
• Review filing history

Using digital services can reduce phone wait times and resolve issues more quickly.

However, for complex or urgent matters, calling remains the most direct method of communication.
