Three Rules for Any IRS Letter
Do not ignore it
Silence can turn a proposed adjustment into an assessment or allow a collection case to progress.
Do not pay it blind
Confirm the IRS used the right income, basis, payments, taxpayer, and tax year before treating the amount as final.
Do not use a generic deadline
The notice in your hand controls. Different codes create different procedures, and the mailing date may be earlier than the day you opened it.
When to hand the letter to a professional
- The amount is material or the calculation involves stock, crypto, a business, rentals, or multiple states.
- The letter mentions levy, lien, a defaulted payment plan, a hearing, or U.S. Tax Court.
- You already responded and the IRS did not resolve the issue.
- Several tax years or unfiled returns are involved.
- You want an authorized representative to obtain records and handle contact.
If the letter identifies a missing return, use the unfiled taxes guide to separate filing work from the later balance-resolution decision.

IRS Notice FAQs
How do I identify an IRS notice?
Look for a notice or letter number near the top or bottom of the first page, then confirm the taxpayer, tax form, tax year, response date, and IRS contact information. Search by the complete code, not only the words “IRS letter.”
Should I call the IRS as soon as I receive a letter?
First read the complete notice and gather the return, payments, and correspondence it references. A prepared call is more useful than an improvised explanation. If a petition, hearing, or levy deadline is close, obtain professional help immediately.
Should I pay the amount on an IRS notice?
Verify it first. Some notices correctly reflect a filed balance; others involve missing payments, incomplete third-party information, duplicated income, or missing basis. Paying without reconciliation can make a correctable account problem harder to unwind.
Can Taxstra speak to the IRS for me?
A taxpayer can authorize a qualified representative for specified matters using Form 2848. Taxstra handles IRS-level notice and collection representation within the scope of an engagement and coordinates with legal counsel when court representation is needed.
