Received an IRS Notice? What to Do Before You Respond

 Receiving a letter from the Internal Revenue Service (IRS) can immediately create anxiety. You may wonder whether you made a mistake, owe additional taxes, or are facing an audit.

But an IRS notice does not automatically mean that you are being audited or accused of wrongdoing.

The IRS sends notices for many different reasons, including tax-account changes, missing information, balance-due situations, payment issues, identity verification, refund adjustments, and requests for additional documentation. The correct response depends on the specific notice you received.

For taxpayers and business owners in New Jersey, Pennsylvania, and throughout the United States, the most important thing is to avoid reacting before understanding what the IRS is actually asking you to do.

If you receive an IRS notice, first identify the notice number, tax year, reason for the notice, amount involved, and response deadline. Then compare the IRS information with your tax return and supporting records before deciding whether to pay, provide documentation, or dispute the notice.

That simple process can help you avoid unnecessary mistakes.

An IRS Notice Is Not Always an IRS Audit

One of the biggest misconceptions about IRS correspondence is that every notice means an audit.

It doesn't.

An IRS notice may simply tell you that:

  • A payment was not recorded

  • Information on your return differs from IRS records

  • Additional information is required

  • Your refund amount changed

  • A balance is due

  • Your identity needs to be verified

  • A tax calculation was adjusted

  • The IRS needs documentation

  • Collection activity is beginning

An audit, on the other hand, involves an examination of specific tax-return information and supporting records.

The distinction matters because your next step should be based on the actual notice - not on assumptions about what the letter means.

What Should You Do After Receiving an IRS Notice?

The first thing to do is not panic and not immediately send money or documents.

Instead, follow this basic process:

  1. Read the entire notice.

  2. Identify the notice or letter number.

  3. Check the tax year or period.

  4. Understand why the IRS contacted you.

  5. Find the response deadline.

  6. Review the related tax return.

  7. Compare the IRS information with your records.

  8. Decide whether you agree or disagree.

  9. Follow the instructions printed on the notice.

  10. Consider professional CPA assistance if the issue is complicated.

The IRS itself uses notice-specific instructions, so taxpayers should rely on the deadline and response method provided on their particular notice rather than assuming every IRS letter follows the same timeline.

1. Start by Identifying the IRS Notice

Before you decide what to do, find the identifying number on the letter.

Many IRS notices have a CP number or Letter/LTR number. This number helps identify the type of communication and the issue involved.

Also check:

  • Your name or business name

  • Taxpayer identification information

  • Tax year

  • Tax form involved

  • Amount shown

  • Reason for the notice

  • Response instructions

  • Deadline

For a business, also determine whether the notice relates to:

  • Business income

  • Payroll taxes

  • Estimated taxes

  • Corporate taxes

  • Partnership filings

  • Information returns

  • Deductions

  • Payments

  • Penalties or interest

Having these details organized makes it much easier to determine what needs to happen next.

2. Compare the IRS Notice With Your Tax Records

Don't assume that the IRS information is correct simply because the letter came from the IRS.

At the same time, don't automatically assume the IRS is wrong.

Compare the notice with your own records.

Depending on the issue, you may need to review:

  • Federal tax returns

  • W-2 forms

  • 1099 forms

  • Bank statements

  • Payroll records

  • Invoices

  • Receipts

  • Accounting reports

  • Estimated tax payment records

  • Brokerage statements

  • Depreciation schedules

  • Prior correspondence

For business owners, accurate bookkeeping can be particularly important because the IRS notice may involve information that originates from the company's accounting records.

A reliable accounting system creates a connection between:

Tax Return → Financial Records → Accounting Ledger → Supporting Documentation

That documentation can make it easier to determine whether the IRS adjustment is accurate.

3. Determine Whether You Agree With the IRS

Once you've compared the notice with your records, there are generally two directions.

You agree

If your review confirms that the IRS information is correct, follow the instructions on the notice.

Depending on the situation, that could involve:

  • Making a payment

  • Providing requested information

  • Correcting a filing

  • Following additional IRS instructions

If you cannot pay the full amount, don't simply ignore the notice. Depending on your circumstances, payment arrangements or other collection options may be available.

You disagree

If you believe the IRS information is incorrect, carefully follow the dispute instructions provided with your specific notice.

A strong response should generally explain:

What is wrong → Why it is wrong → What evidence supports your position

For example, if the IRS says a payment was missing, your response may need to include documentation showing when and how that payment was made.

The objective should be a clear, documented response, rather than an emotional or unsupported disagreement.

4. Never Ignore the IRS Deadline

The deadline printed on your IRS notice is one of the most important pieces of information in the entire letter.

Different IRS notices can have different response periods. Depending on the type of notice, the consequences of missing a deadline can include additional tax, penalties, interest, collection activity, or loss of certain administrative or judicial rights.

Create a reminder as soon as you receive the notice.

A useful approach is to create three dates:

IRS Deadline
The official date printed on the notice.

Document Preparation Date
The date by which you want all supporting records organized.

Professional Review Date
An earlier date if you plan to have a CPA or tax professional review the response.

This gives you time to identify missing information rather than discovering a problem immediately before the IRS deadline.

5. Be Careful About Sending Too Much Information

One common mistake is responding to an IRS notice by sending every financial document available.

More documentation isn't necessarily better.

Your response should generally address what the IRS actually requested and include relevant evidence supporting your position.

For example, if the IRS is asking about a particular income discrepancy, sending unrelated business records may create unnecessary confusion.

Organize your response around the specific issue.

A useful documentation structure:

IRS Question
What does the notice say?

Your Position
What do you believe is correct?

Supporting Evidence
Which records prove your position?

Requested Action
What do you want the IRS to correct or recognize?

This creates a much clearer response.


6. Business Owners Need to Look Beyond the Tax Notice

For businesses, an IRS notice can sometimes reveal an accounting or bookkeeping issue that needs attention beyond the immediate letter.

For example, an issue involving reported income may require reviewing:

  • Sales records

  • Bank deposits

  • Payment processors

  • Accounts receivable

  • 1099 information

  • General ledger entries

A payroll-related notice may require reviewing:

  • Payroll reports

  • Payroll tax deposits

  • Employee records

  • Payroll filings

This is why IRS notice assistance for businesses often involves more than simply writing a response letter.

The underlying accounting records may need to be reviewed first.

7. When Should You Contact a CPA About an IRS Notice?

Not every IRS letter requires professional representation.

However, professional assistance can be particularly useful when:

  • The amount involved is significant

  • You don't understand the notice

  • The IRS is proposing a tax adjustment

  • You disagree with the IRS

  • Multiple tax years are involved

  • Your business received the notice

  • Payroll taxes are involved

  • You have missing records

  • You may owe penalties or interest

  • The notice involves an audit or examination

  • You are concerned about collection activity

  • You need help understanding your options

A CPA can review the notice alongside your tax return and accounting records and help determine the appropriate next step.

Common Mistakes to Avoid When Responding to an IRS Notice

Ignoring the Letter

Not responding does not make the issue disappear.

Paying Immediately Without Reviewing

First determine whether the amount shown is accurate.

Assuming Every Notice Is an Audit

An IRS notice and an IRS audit are not automatically the same thing.

Missing the Deadline

Always follow the response date stated on your specific notice.

Sending Unorganized Documents

Relevant records should be organized around the issue being addressed.

Disagreeing Without Evidence

If you believe the IRS is wrong, support your position with documentation.

Waiting Until the Last Day

Complex tax issues may require time to retrieve records and obtain professional review.

Altering or Creating Records

Never change or manufacture documents to support a tax position. If records are missing, address the problem honestly and seek professional guidance.
