Choose the Correct IRS Support Route

The IRS has different support routes for individual taxes, business taxes, refunds, notices, identity theft, tax payments, in-person appointments, and unresolved problems. Choose the route that matches your issue before calling.

Individual Tax Returns and General Tax Account Questions

For individual income tax returns, tax account questions, IRS letters, tax transcripts, payment questions, or general IRS assistance, call 1-800-829-1040. The IRS says this line is open Monday-Friday, 7:00 AM-7:00 PM local time.

Business Tax Questions

For business returns, employer identification numbers, payroll taxes, business account questions, federal tax deposits, partnerships, corporations, trusts, and other business tax matters, call the IRS Business and Specialty Tax Line at 1-800-829-4933.

Refund Status and Missing Refund Checks

For refund status, start with the IRS “Where’s My Refund?” tool. If you need the automated refund hotline, call 1-800-829-1954. For some missing refund check issues or married-filing-jointly refund traces, you may need to speak with an IRS representative at 1-800-829-1040.

Payment Plans and Installment Agreements

For payment plans, start with the IRS online payment agreement tool when possible. Individuals who cannot apply or revise a payment plan online can call 1-800-829-1040. Business taxpayers can call 1-800-829-4933 or the number shown on their IRS notice.

IRS Notices and Letters

If you received an IRS notice or letter, read it carefully and use the phone number or instructions printed on the notice when available. You can also search the notice number on IRS.gov to understand what it means and what action may be required.

Identity Theft, IP PINs, and Suspicious Tax Returns

For identity theft, IP PIN, or suspicious tax-return activity, call 1-800-908-4490 when IRS instructions tell you to use that number. The IRS says this number is for identity and return-status verification, not general refund status or tax account questions.

In-Person IRS Appointments

IRS Taxpayer Assistance Centers generally require appointments. To schedule an appointment at a local IRS office, call 1-844-545-5640. Check IRS.gov first to see what services are available at the office near you.

Taxpayer Advocate Service

If you have tried to resolve a tax problem with the IRS and still need help, the Taxpayer Advocate Service may be able to assist. TAS can be reached at 1-877-777-4778.

What to Have Ready Before Calling the IRS

Before calling the IRS, gather the information needed to verify your identity and explain your issue. IRS representatives may not be able to help if you do not have enough identifying information.

• Your Social Security number, ITIN, or EIN
• Filing status and tax year involved
• Copy of the tax return you are calling about
• IRS notice or letter number, if you received one
• Taxpayer name, address, date of birth, and contact information
• Refund amount, filing date, and direct deposit information if calling about a refund
• Payment confirmation number, canceled check, or bank record if calling about a payment
• Business name, EIN, and authorized representative details for business calls
• Form 2848 or Form 8821 if you are calling for another taxpayer
• Prior case numbers, transcripts, account notices, or Taxpayer Advocate contacts
• Pen and paper to write down the representative name, date, time, and case notes

Common IRS Customer Service Issues

Taxpayers commonly contact the IRS for help with:

• Refund status, delayed refunds, missing refund checks, or refund traces
• IRS notices, letters, balance-due notices, and response deadlines
• Payment plans, installment agreements, and payment changes
• Tax transcripts, prior-year returns, and account records
• Identity theft, IP PINs, rejected returns, and suspicious tax activity
• Business tax accounts, EIN issues, payroll taxes, and deposits
• Amended returns and return-processing delays
• Taxpayer Assistance Center appointments
• Penalty, interest, levy, lien, or collection questions
• Taxpayer Advocate Service escalation
• IRS impersonation scams, phishing emails, and fake refund messages

IRS Refund Help

For refund status, the fastest starting point is usually the IRS “Where’s My Refund?” tool on IRS.gov. You can also use the automated refund hotline at 1-800-829-1954. Refund information may not be available immediately after filing, and amended return information is handled separately.

If your refund check was lost, stolen, destroyed, or never arrived, the IRS may require a refund trace. If you filed married filing jointly, the automated systems may not be able to start the trace, so you may need to call and speak with a representative.

IRS Payment Plans and Balance-Due Notices

If you owe taxes and cannot pay in full, the IRS offers payment options that may include short-term and long-term payment plans. Many taxpayers can apply or revise a payment plan online, but eligibility depends on the amount owed, filing status, tax type, and whether required returns have been filed.

If you receive a balance-due notice, use the phone number and deadline printed on the notice. Keep copies of all payments, confirmation numbers, installment agreement letters, and IRS correspondence.

IRS Notices, Letters, and Deadlines

Do not ignore an IRS notice or letter. It may involve a tax return correction, missing information, balance due, refund change, identity verification, audit, collection action, or other deadline. Search the notice number on IRS.gov and follow the instructions listed on the notice.

If you disagree with a notice, contact the IRS using the notice instructions and keep copies of all documents you send. Do not send original records unless the IRS specifically instructs you to do so.

IRS Identity Theft and IP PIN Help

If you believe someone used your Social Security number, ITIN, or tax information to file a return, follow IRS identity-theft instructions immediately. The IRS identity theft number at 1-800-908-4490 is used for specialized identity and return-status verification.

If you have an Identity Protection PIN, keep it secure. The IRS may reject a tax return if the correct IP PIN is missing or incorrect. If you cannot retrieve your IP PIN online, contact the IRS through the official IP PIN assistance process.

In-Person Help at an IRS Taxpayer Assistance Center

If your issue cannot be resolved online or by phone, you may need an appointment at an IRS Taxpayer Assistance Center. Call 1-844-545-5640 to schedule. Before visiting, confirm the services offered at that location and bring government-issued photo ID, taxpayer identification information, and any IRS notices or forms related to your issue.

IRS Scam and Fraud Warnings

Be cautious with phone calls, emails, texts, social media messages, or letters claiming to be from the IRS. Scammers often threaten arrest, demand immediate payment, promise fake refunds, request gift cards, ask for cryptocurrency, or try to collect personal and financial information.

• The IRS does not initiate contact by email or social media to request personal or financial information.
• Do not pay a caller who demands gift cards, wire transfers, cryptocurrency, or payment apps.
• Do not click links in suspicious IRS emails or text messages.
• Forward suspicious IRS-related emails to phishing@irs.gov.
• Report IRS impersonation scams to TIGTA or call 1-800-366-4484.
• If you think you actually owe taxes, go directly to IRS.gov or call the IRS using an official number.

How to Escalate an IRS Complaint

If your IRS issue is not resolved after your first call or online attempt, take these steps:

1. Write down the date, time, phone number called, and summary of each contact.
2. Ask whether the IRS representative can provide a case number, referral number, or specific next step.
3. Keep copies of IRS notices, letters, returns, forms, transcripts, payments, and mailing receipts.
4. Use the number or instructions on your IRS notice when one is provided.
5. If the problem involves a missed deadline, respond in writing before the deadline when possible.
6. If you mailed documents, use a trackable mailing method and save proof of delivery.
7. If the IRS issue is causing financial hardship or has not been resolved through regular channels, contact the Taxpayer Advocate Service at 1-877-777-4778.
8. For IRS impersonation scams, report the suspicious contact to TIGTA and phishing@irs.gov.
