How the IRS Contacts You: The Methods, Timing, and What to Do

The IRS reaches you through mail, phone, or in person — and the method depends on what they need

The IRS does not contact people by email, text message, or social media. If you receive a message claiming to be from the IRS through any of those channels, it is a scam. The IRS initiates contact in three ways: U.S. mail, telephone, or in-person visits. Mail is by far the most common. When the IRS needs to tell you something — that you owe money, that they are auditing your return, that they need more information — they send a letter to the address on file with your most recent tax return.

Phone calls happen less often and usually only after the IRS has already sent you mail and received no response. In-person visits are rare and typically happen only in criminal investigations or when the IRS is trying to collect a very large debt. Understanding which method the IRS is using, and why, helps you know whether the contact is real and what you should do next.

Key Takeaways

• The IRS contacts you by mail first in almost all cases, sending letters to the address on your most recent tax return.
• Real IRS mail includes a notice number, the specific tax year in question, and a mailing address you can write to — scam letters do not.
• The IRS will call you only after sending mail, and only if you have not responded; they will never ask for payment by gift card, wire transfer, or prepaid debit card.
• If the IRS visits your home or business in person, they will show you a badge with their name and IRS credentials before discussing anything.
• You can contact the IRS yourself by phone, mail, or through your tax professional instead of waiting for them to reach out.

How the IRS sends mail and what the letter will say

When the IRS mails you a notice, it goes to the address listed on your most recent tax return. If you have moved, the letter may arrive late or not at all — which is why the IRS recommends updating your address with them before filing. The letter will have a notice number at the top, such as CP2000 or CP2501. This number tells you what the IRS is contacting you about. A CP2000, for example, means the IRS found a discrepancy between what you reported and what a third party (like your employer or bank) reported to them.

Real IRS letters include the specific tax year in question, an explanation of why they are writing, what you owe (if anything), and a mailing address where you can send a response. The letter will also include a phone number you can call, though that number is for questions about the letter itself, not for making a payment. The IRS does not ask you to call a number in the letter to pay by phone when ready. If you owe money, the letter will explain your options, which usually include paying in full, setting up a payment plan, or requesting more time to respond.

Scam letters often lack a notice number, use vague language about "your account," demand when ready payment, or ask you to call a number to verify personal information. If you are unsure whether a letter is real, you can call the IRS directly at 1-800-829-1040 (the main IRS customer service line) and ask them to verify it. Do not use a phone number from the letter itself if you suspect it is a scam.

When and why the IRS calls you

The IRS calls taxpayers far less often than it sends mail, and only under specific circumstances. The most common reason is that you did not respond to a mailed notice within the timeframe given in the letter. If the IRS has sent you mail and heard nothing back, they may call to confirm they have the right phone number and to ask whether you received the letter. Another reason for a call is that the IRS is trying to collect a debt and has exhausted other methods.

When the IRS calls, the agent will identify themselves by name and badge number and will tell you which IRS office is calling. They will ask questions to verify your identity — such as your Social Security number or the amount of tax you owe — but they will never ask for payment information over the phone during the initial call. If you are unsure the call is real, you can hang up, call the IRS main line at 1-800-829-1040, and ask them to verify that someone from their office tried to reach you. The IRS will never threaten you with arrest, demand payment by gift card or wire transfer, or tell you that you must pay when ready or face legal action.

If you receive a call claiming to be from the IRS and the caller asks for payment by gift card, iTunes card, wire transfer, or prepaid debit card, it is a scam. Hang up and report it to the Treasury Inspector General for Tax Administration (TIGTA) at 1-800-366-4484 or online at tigta.gov.

In-person visits from IRS agents

The IRS rarely shows up at your home or business without warning. When they do, it is usually for one of two reasons: they are conducting a criminal investigation, or they are trying to collect a very large debt and other methods have failed. In either case, the agent will have credentials — a badge with their photograph, name, and the IRS seal. Ask to see this badge before you let them inside or answer any questions. You have the right to ask for their name, badge number, and the IRS office they work for.

If an IRS agent appears at your door, you do not have to let them inside your home or business without a warrant. You can ask them to leave and contact your tax professional or a tax attorney before speaking with them further. If they have a warrant, they will show it to you. A warrant is a court order signed by a judge, not a letter from the IRS. If you are unsure whether what they are showing you is a real warrant, you can ask to call your attorney before proceeding.

How to tell a real IRS contact from a scam

Scammers impersonate the IRS because people fear the agency and often act quickly when they think they owe money. Here are the clearest signs that a contact is not from the real IRS:

• The IRS will never contact you by email, text message, social media, or through a pop-up on your computer.
• The IRS will never demand when ready payment or threaten arrest, wage garnishment, or driver's license revocation as a first step.
• The IRS will never ask you to pay by gift card, iTunes card, wire transfer, or prepaid debit card.
• The IRS will never ask you to verify your Social Security number, PIN, or credit card number over the phone without you initiating the call.
• A real IRS letter will have a notice number, a specific tax year, and a mailing address for your response.

If you receive what you think is a scam, report it to TIGTA at 1-800-366-4484 or tigta.gov. You can also report it to the Federal Trade Commission at reportfraud.ftc.gov. Reporting these scams helps the government track patterns and shut down the criminals behind them.

What to do if the IRS contacts you

If you receive a letter from the IRS, read it carefully and note the notice number and the important date for responding. Most IRS notices give you 30 days to respond, though some give you longer. You do not have to respond when ready, and you do not have to pay when ready. If you disagree with what the IRS is saying, you can request an explanation or ask for a conference with an IRS representative. The letter will tell you how to do this.

If you cannot pay what you owe, you can request a payment plan (called an installment agreement) or ask for more time to pay. You can also contact a tax professional — a CPA, enrolled agent, or tax attorney — to represent you. Once you give a tax professional a power of attorney form, the IRS will contact them instead of you. If you receive a phone call from someone claiming to be from the IRS and you are unsure it is real, hang up and call 1-800-829-1040 to verify.

How to contact the IRS yourself

You do not have to wait for the IRS to contact you. If you have questions about your tax return, think you may owe money, or want to set up a payment plan, you can reach out first. The main IRS customer service line is 1-800-829-1040, available Monday through Friday. You can also write to the IRS at the address shown on your most recent notice or return. If you have a tax professional, they can contact the IRS on your behalf.

The IRS also has an online account tool called IRS Online Services (available at irs.gov) where you can view your account balance, payment history, and any notices the IRS has sent you. To use this tool, you will need to create an account and verify your identity. This can be faster than calling if you just need to check your balance or see what the IRS has on file.

Frequently Asked Questions

Can the IRS contact me by email or text?

No. The IRS will never initiate contact by email, text message, social media, or when ready messaging. If you receive a message claiming to be from the IRS through any of these channels, it is a scam. You can report it to TIGTA at 1-800-366-4484.

What should I do if I receive a call from someone claiming to be from the IRS?

Ask for their name, badge number, and the IRS office they work for. Do not give them any personal information. Hang up and call the IRS main line at 1-800-829-1040 to verify the call was real. If they asked for payment by gift card or wire transfer, it was definitely a scam.

How long do I have to respond to an IRS letter?

Most IRS notices give you 30 days to respond, though some give you longer. The important date will be clearly stated in the letter. You can request more time if you need it by contacting the IRS office listed in the letter.

Do I have to let an IRS agent into my home?

No. You can ask them to leave or to come back with a warrant. A warrant is a court order signed by a judge. If you are unsure whether what they are showing you is a real warrant, you can ask to call your attorney before letting them proceed.

What if I cannot pay what the IRS says I owe?

You have options. You can request a payment plan, ask for more time to pay, or request that the IRS review the amount. The letter will explain how to do this. You can also contact a tax professional to represent you and negotiate on your behalf.
