IRS Phone Number 2026 — How to Contact the IRS by Phone

IRS Phone Numbers

The Internal Revenue Service operates several phone lines depending on the type of tax issue you need help with. Using the correct number ensures you reach the right department faster and reduces hold times. Below are the official IRS phone numbers for 2026, verified against IRS.gov telephone assistance.

Individual Taxpayer Assistance — 1-800-829-1040

This is the main IRS phone number for individual taxpayers. Call this number for personal income tax questions, tax return help, payment arrangements, notice responses, and general account inquiries. Have your Social Security number and tax return ready before calling to speed up verification.

Business Tax Assistance — 1-800-829-4933

Business owners and self-employed individuals should use 1-800-829-4933 for business tax questions. This line covers employer identification numbers (EIN), business tax returns, employment taxes, excise taxes, and business payment plans. Hours are the same: 7 AM to 7 PM local time, Monday through Friday.

Tax-Exempt Organizations — 1-877-829-5500

Nonprofits, charities, and other tax-exempt organizations can reach the IRS at 1-877-829-5500. This line handles questions about tax-exempt status, Form 990 filings, unrelated business income, and revocation issues.

Refund Hotline — 1-800-829-1954

To check your federal tax refund status, call the IRS refund hotline at 1-800-829-1954. This is an automated 24/7 service — you will need your Social Security number or ITIN, your filing status, and the exact refund amount shown on your return. For faster service, use the 'Where's My Refund?' online tool or the IRS2Go mobile app instead of calling.

Payment Options & Plans — 1-888-353-4537

If you cannot pay your full tax bill, call the IRS payment plan line at 1-888-353-4537 to set up an installment agreement or discuss other payment options. This line is separate from the main assistance number.

Priority Service for Tax Practitioners — 1-866-860-4259

Tax professionals and enrolled agents can use the Practitioner Priority Service line at 1-866-860-4259 for faster access to IRS account information for their clients.

Best Times to Call the IRS

Calling the IRS at the right time can save you 15-30 minutes or more of hold time. The IRS handles millions of calls per year, and demand varies significantly by season, day of week, and time of day. Here is the optimal calling strategy based on historical call volume data.

By Season

Peak season (February through April): This is when the IRS receives the most calls — over 100 million calls annually, with the heaviest volume concentrated in March and April. Wait times regularly exceed 30 minutes during this period. If you can wait until after April 15 or before February, you will experience significantly shorter hold times.

Off-season (May through January): Call volumes drop dramatically after the tax filing deadline. Wait times average 5-10 minutes during this period, and you are much more likely to reach a live person quickly. Summer and fall are the best times for non-urgent IRS matters.

By Day of Week

Best days: Tuesday, Wednesday, and Thursday tend to have the shortest wait times. Mid-week call volumes are generally lower as callers are distributed more evenly.

Worst days: Monday (highest call volume from people who put off calling over the weekend) and Friday (callers trying to resolve issues before the weekend). Avoid calling on or immediately after federal holidays and tax deadlines (April 15, June 15, September 15, and January 15).

By Time of Day

• Best time: 7 AM to 8 AM local time — the IRS lines have just opened and call volume is lowest. You will typically reach someone in under 10 minutes.
• Second best: 5 PM to 7 PM local time — late afternoon/evening hours see reduced volume as many callers have given up or left work.
• Worst time: 12 PM to 2 PM local time — lunch hours see a spike in call volume and many agents may be on break.

By Type of Call

Refund status calls are best handled through the 'Where's My Refund?' online tool, which updates overnight and gives you the same information without waiting on hold. Payment-related calls should be made early in the month, as end-of-month and mid-March through April are busiest for payment processing.

How to Reach a Live Person at the IRS

Getting through to a live IRS agent can be challenging, especially during peak season. The phone menu system is designed to route callers to automated services first, but with the right strategy, you can speak to a real person. Here are the most effective methods.

Strategy 1: Follow the Specific Menu Prompts

When you call 1-800-829-1040, listen carefully to all menu options. Do not say "representative" or "agent" right away — the system may route you back to automated services or hang up. Instead, select the option that most closely matches your specific reason for calling:

• For refund status: Use the automated refund option or call 1-800-829-1954 directly
• For payment plans: Select the payment/collection option
• For notice responses: Select the notice/letter option and enter the notice number
• For general questions: Select the "other" or "general information" option

Once you have navigated through the relevant menu tree, you will typically be offered the option to speak with a representative.

Strategy 2: Use the "0" or Repeated Key Press Method

Some callers report success by pressing 0 repeatedly at the initial menu or after the first prompt. While not guaranteed to work on all menu iterations, this can sometimes bypass menu layers. Similarly, saying "agent" after the first menu prompt may route you to a representative — but only try this after you have listened to the initial menu options.

Strategy 3: Call at the Right Time

Even with the best menu navigation, calling during peak hours will result in long waits. Use the timing guidance in the Best Times to Call section. Calling at 7 AM sharp when lines open gives you the best chance of reaching a live person with minimal hold time.

Strategy 4: Ask for a Transfer

If you reach an agent but they cannot handle your specific issue, politely ask if they can transfer you to the correct department rather than having you hang up and call a different number. Agents can often transfer you directly, saving you from starting the hold process over.

What to Do If You Cannot Get Through

If you have tried multiple times and cannot reach a live person, consider these alternatives:

• Visit a local IRS Taxpayer Assistance Center (TAC) for in-person help — appointments are recommended
• Use the IRS Online Account to view your balance, make payments, and access tax records
• Contact the Taxpayer Advocate Service if you are experiencing financial hardship or have not been able to resolve an IRS issue through normal channels

What to Have Ready Before Calling the IRS

Being prepared before you call the IRS can make the difference between a 5-minute call and a 30-minute ordeal. IRS representatives need to verify your identity before discussing any account information. Having these items ready will speed up the process significantly.

Essential Documents

• Social Security number or ITIN — for yourself, your spouse, and any dependents listed on your return
• Full name and date of birth — matching what is on file with the IRS
• Filing status — single, married filing jointly, married filing separately, head of household, or qualifying widow(er)
• Tax return for the year in question — have a copy of your complete return, including all schedules and forms
• IRS notice or letter — if you received one, have the notice number (CP___ or LTR___), the tax year, and the amount shown on the notice
• Prior year tax return — for identity verification purposes, the IRS may ask questions about your prior year return

Payment-Related Items

If you are calling about a payment, installment agreement, or offer in compromise, also have:

• Bank account and routing numbers
• Credit card information (if paying by card)
• Monthly income and expense information
• Information about assets (bank accounts, investments, property)

What to Write Down During Your Call

Keep a pen and paper handy. During the call, note:

• The agent's name and ID number
• The date and time of the call
• Any confirmation numbers, case numbers, or reference IDs provided
• Exactly what was discussed and what actions were promised
• Any follow-up steps or deadlines mentioned

Have Reasonable Expectations

IRS agents handle complex cases and have strict verification protocols. They cannot discuss your account without successful identity verification. They also cannot provide legal advice or guarantee specific outcomes. If you need representation, consider consulting a tax professional who can communicate with the IRS on your behalf as your authorized representative.

Common Reasons to Call the IRS

Millions of taxpayers call the IRS each year for a variety of reasons. Understanding which issues are best handled by phone — and which can be resolved online — will save you time. Here are the most common reasons taxpayers call the IRS and the best way to handle each.

1. Checking Refund Status

This is the most common reason people call the IRS, accounting for a significant portion of all calls. Do not call for this. Use the 'Where's My Refund?' tool on IRS.gov or the IRS2Go mobile app instead. The online tool updates overnight and provides the same information the phone agents have. You will get your answer in under 2 minutes without waiting on hold. If the tool says your refund has been issued but you have not received it, then call the refund hotline at 1-800-829-1954 or the main line after a waiting period (typically 5 days for direct deposit, 6 weeks for paper check).

2. Setting Up a Payment Plan

If you owe taxes and cannot pay in full, you can set up an installment agreement online through the IRS Online Payment Agreement tool. For simple payment plans, the online process takes about 10 minutes. Call 1-888-353-4537 only if you need a plan longer than 72 months, need to modify an existing plan, or if the online system cannot process your request.

3. Responding to an IRS Notice or Letter

The IRS sends millions of notices each year (CP notices, LTR notices, etc.). Before calling, read the notice carefully — most notices explain exactly what you need to do and include a response deadline. Many notices can be resolved by mail or online without a phone call. If you need to call, have the notice number (CP or LTR number) and the amount shown on the notice ready. Common notices include CP2000 (underreported income), CP14 (balance due), and LTR 3175C (identity verification).

4. Identity Verification

If you receive an IRS letter (such as LTR 5071C or 6331C) asking you to verify your identity, you will need to call the number provided in the letter or visit an IRS office in person with two forms of ID. This is one situation where you must call — it cannot be handled through standard online tools. The identity verification process is crucial for preventing tax refund fraud.

5. Amending a Tax Return

If you need to correct a filed tax return, you file Form 1040-X. While the amended return itself is filed by mail (or electronically for 2019+ returns), you may need to call if you have questions about the amendment process, need to check the status of a filed amendment, or need help calculating the correct figures. Amendment processing typically takes 16-20 weeks.

6. Questions About Stimulus Payments or Tax Credits

For questions about the Child Tax Credit, Earned Income Tax Credit, Recovery Rebate Credit (if applicable), or other credits, the main IRS line can help. However, use the Interactive Tax Assistant on IRS.gov first — it answers many credit-related questions without a phone call.

7. Employer Identification Number (EIN) Issues

Business owners can apply for an EIN online instantly at IRS.gov. If you need help with an existing EIN, have questions about business tax forms, or need to verify your business information, call the business line at 1-800-829-4933.

IRS Phone Assistance Hours

The IRS operates its telephone assistance during specific hours. Calling outside these hours will result in a recorded message asking you to call back. Know the exact hours before you dial.

Federal Holiday Closures

The IRS is closed on all federal holidays, even if the phone lines are normally open. If a federal holiday falls on a Monday, the IRS will be closed that entire day. Federal holidays observed by the IRS include:

• New Year's Day (January 1)
• Martin Luther King Jr. Day (third Monday in January)
• Presidents' Day (third Monday in February)
• Memorial Day (last Monday in May)
• Juneteenth (June 19)
• Independence Day (July 4)
• Labor Day (first Monday in September)
• Columbus Day (second Monday in October)
• Veterans Day (November 11)
• Thanksgiving Day (fourth Thursday in November)
• Christmas Day (December 25)

Extended Hours During Peak Season

During the tax filing season (February through April), the IRS may offer extended Saturday hours for certain services. These are announced each year on IRS.gov. In 2025 and 2026, the IRS has expanded Saturday hours at many Taxpayer Assistance Centers for in-person help. Phone hours may also be extended closer to the April 15 filing deadline. Check IRS.gov/help for the latest seasonal schedule.

Alternative Ways to Contact the IRS

Phone is not the only way to reach the IRS, and for many issues, alternative methods are faster and more convenient. Here are all the ways you can contact or interact with the IRS without waiting on hold.

Online Tools (Recommended)

• 'Where's My Refund?' — Check refund status online. Updates overnight. Available 24/7. Also on the IRS2Go mobile app.
• IRS Online Account — View your balance, make and schedule payments, access tax records and transcripts, and approve payment plans. Requires ID.me verification.
• IRS Payment Options — Pay by direct debit, credit/debit card, or electronic funds withdrawal. Set up installment agreements.
• Interactive Tax Assistant (ITA) — Answer a series of questions to get answers to common tax law questions. Covers over 100 topics.
• Get Transcript — Request your tax return transcript and wage and income transcripts online or by mail.

Instead of calling the IRS to request prior-year tax data or verify income, you can use the online tax transcript tool to instantly download your return and account transcripts — no wait time required.

IRS2Go Mobile App

The official IRS2Go mobile app is available for iOS and Android. It provides access to 'Where's My Refund?', payment options, free tax preparation resources, and helpful tax tips. The app uses the same secure authentication as the IRS website.

In-Person Assistance (Taxpayer Assistance Centers)

The IRS operates Taxpayer Assistance Centers (TACs) in most major cities where you can meet with an IRS representative in person. Appointments are strongly recommended — walk-ins are accepted only if availability allows. To find your local TAC, use the IRS office locator. Bring two forms of identification and any relevant notices or documents.

Mail Correspondence

For certain issues, you can correspond with the IRS by mail. The address depends on your specific issue and is listed on any notice you received. General correspondence addresses are available on IRS.gov. Allow 6-8 weeks for a response when contacting the IRS by mail. Certified mail with return receipt requested provides proof of delivery.

Taxpayer Advocate Service (TAS)

The Taxpayer Advocate Service is an independent organization within the IRS that helps taxpayers who are experiencing economic hardship or have been unable to resolve an issue through normal IRS channels. You can reach TAS at 1-877-777-4778 or through their website at taxpayeradvocate.irs.gov. TAS services are free and confidential.

Social Media

The IRS maintains official social media accounts on Twitter/X (@IRSnews for news and updates, @IRSInnocentSpouse for innocent spouse relief information) and Facebook. While you cannot discuss personal tax issues through social media, these accounts provide timely updates on tax law changes, deadlines, scams, and service disruptions.

IRS Contact During Tax Season vs Off-Season

The IRS experience differs dramatically between tax season (January through mid-April) and the rest of the year. Understanding these differences will help you decide when to call and what to expect.

Tax Season (January 1 – April 15)

• Call volume: Extremely high. The IRS receives over 40% of its annual calls during this 3.5-month period. Over 3 million calls per week at peak.
• Wait times: Average 15-30+ minutes, with spikes over 60 minutes on Mondays and near deadlines.
• Services: Full range of phone services available. Extended hours may be offered on Saturdays.
• Best approach: Use online tools whenever possible. If you must call, do so at 7 AM sharp on a Tuesday or Wednesday.

Off-Season (April 16 – December 31)

• Call volume: Significantly lower. Wait times average 5-10 minutes.
• Services: Most services available, but some seasonal programs (like free tax preparation) may not be running.
• Best approach: Much easier to reach a live person. Ideal time for non-urgent account questions, payment plans, and notice responses.
• Note: The IRS is closed during federal government shutdowns (if applicable), which can disrupt off-season operations.

Extended Filing Season (April 16 – October 15)

For taxpayers who file an extension, the IRS remains available for questions related to extended returns. However, call volumes drop significantly after April 15, and wait times are generally much lower even during this period. Filing an extension gives you more time to prepare your return, but any tax owed is still due by April 15 to avoid penalties and interest.

Year-End and Holiday Period (November – December)

This is the quietest time of year for IRS phone lines. Wait times are typically under 5 minutes, making it the absolute best time to call for any non-urgent issues. However, the IRS may have reduced staffing during the holiday weeks. Plan your calls for early December or late January for the best experience.

IRS Processing Updates for 2026

The IRS has continued to modernize its phone systems and processing capabilities in 2026. Key improvements include:

• Enhanced call-back technology — you can request a call-back instead of waiting on hold during non-peak periods
• Improved interactive voice response (IVR) system with smarter routing
• Expanded online account capabilities reducing the need to call
• Increased staffing levels with improved training for phone assistors

International IRS Phone Numbers

If you are calling the IRS from outside the United States, you cannot use the toll-free 1-800 numbers. You must call the IRS's international telephone number instead. International callers should be aware of time zone differences and potentially higher calling costs.

IRS International Number

Callers outside the US should dial: +1-267-941-1000 (not toll-free)

This number reaches the IRS's international customer service team. Hours of operation are 7:00 AM to 7:00 PM Eastern Time, Monday through Friday. Standard international calling rates apply — this is not a toll-free number.

For US Citizens Living Abroad

US citizens, permanent residents, and expatriates living outside the United States can also call the main IRS number 1-800-829-1040 if they use a US-based virtual phone number or VoIP service that routes through a US exchange. Otherwise, use the international number. The IRS also provides specific resources for expats:

• IRS International Taxpayers Page — guidance for citizens abroad
• FBAR (Foreign Bank Account Report) questions: check IRS.gov for specific FBAR contact information
• Foreign earned income exclusion (Form 2555): general questions can be directed to the international line

Calling from Canada or Mexico

For callers in Canada and Mexico, the same international number +1-267-941-1000 applies. There are no separate dedicated numbers for specific neighboring countries. Consider using a VoIP service (Skype, Google Voice, etc.) to reach the toll-free US number at reduced rates if you have a US-based virtual number.

Embassy and Consulate Assistance

US embassies and consulates cannot assist with IRS tax issues. They do not have access to IRS systems and cannot forward tax documents or payments. All tax matters must be handled directly with the IRS through the channels listed on this page.

International Mailing Address

If you need to mail tax documents to the IRS from outside the US, use the following address:

Internal Revenue Service
P.O. Box 931000
Louisville, KY 40293-1000
USA

Note: Specific mailing addresses vary by the type of form or payment. Always check the latest address on IRS.gov or on the specific form instructions, as addresses change periodically.

International Taxpayer Advocate

For US taxpayers living abroad who need advocacy assistance, the Taxpayer Advocate Service has a dedicated international team. Contact the TAS office at +1-877-777-4778 (toll-free from the US) or +1-787-522-8601 (from Puerto Rico or international). The TAS website provides specific contact information for international cases.
