Got an IRS Notice in the Mail? What It Means and What to Do Next (Georgia Checklist)

The moment an IRS notice arrives: don’t ignore it

Getting an IRS notice in the mail can trigger instant stress—especially if you’re already behind on filing. But an IRS letter isn’t automatically “bad news,” and it’s rarely something that improves with time. Most notices are asking for one of three things: information, a correction, or payment. The best move is to slow down, read it carefully, and respond by the deadline.

The IRS has repeatedly emphasized a simple point: don’t toss IRS mail. Notices are time-sensitive, and the letter usually includes a notice-specific phone number and instructions for responding. Keeping copies of everything you send (and what they sent you) matters if the issue escalates or repeats.

First: confirm it’s real (and not a scam)

Before sharing information or sending money, verify what you received.

A legitimate IRS notice typically includes:

The IRS logo and formal letter layout
A CP or LTR (letter) number (more on this below)
A tax year referenced (for example, “Tax Year 2022”)
A response deadline
Payment and appeal instructions

If the “notice” came by text, email, or social media, treat it as suspicious. The IRS generally initiates contact by mail.

If you’re in Georgia, there’s another common point of confusion: not every tax letter comes from the IRS. You may receive a letter from the Georgia Department of Revenue (GA DOR). GA DOR maintains guidance for people asking “Did you get a letter?” and shares reminders about what they will and won’t request. When in doubt, confirm the sender using official government websites—never the phone number printed on a suspicious letter.

Find the CP or LTR number—this is the fastest way to identify the notice

One of the most useful steps is also the simplest: look for the CP or LTR number on the first page.

CP numbers (like CP2000) are common “computer-generated” notices.
LTR numbers are IRS letters that often relate to documentation or more specific issues.

This code helps you quickly determine what the IRS is asking for and what your response options are. It also helps a tax professional diagnose the issue faster—especially if you’ve received multiple letters.

What most IRS notices mean (plain-English overview)

While every situation is different, most IRS notices fall into a few buckets:

1) Balance due notices
These say the IRS believes you owe tax, penalties, or interest. The letter should explain the amount and the due date, along with payment options.

2) Missing information / identity verification
Some letters request proof of identity, additional documentation, or clarification. This can happen after suspected fraud, changes to a return, or mismatches in information.

3) Return changes or proposed changes
The IRS may propose adjustments based on information it received from employers, banks, payment platforms, or brokers. A well-known example is the CP2000 series (often tied to underreported income). Importantly, a CP2000 is generally not an audit—it’s a proposed adjustment based on third-party data.

4) Unfiled return notices
If you haven’t filed in a year (or several), the IRS may send reminders or warnings. If the IRS files a return for you (a “substitute for return”), it often doesn’t include deductions and credits you may be entitled to—so the result can look worse than it should.

A Georgia checklist: what to do next (in order)

When someone brings us an IRS notice at Bottom Line Taxes, we focus on a calm, step-by-step process. Here’s a practical sequence that works for most Georgia individuals and businesses.

Open it and read every page. Check the tax year, the amount, and what the IRS is requesting.
Locate the CP/LTR number and the response deadline.
Compare the notice to your records (W-2s, 1099s, brokerage statements, prior returns, IRS transcripts if available).
Don’t call the first number you find online. If calling, use the contact details in the notice or official IRS channels.
Decide whether you agree or disagree. If you agree, follow the instructions to pay or confirm. If you disagree, respond with documentation.
Respond in writing when appropriate—and keep proof. Send mail using tracking, and keep copies of everything.
Address any missing tax returns. If you’re behind on filing, notice resolution often depends on getting prior-year returns filed correctly.

If the notice says you owe: payment plans and “don’t wait” realities

If you truly owe and can’t pay in full immediately, the key is to avoid freezing. Interest and penalties can continue to accrue, and ignoring the notice can lead to more aggressive collection steps.

Common next steps include:

Paying in full (if possible)
Setting up a payment arrangement
Evaluating whether the balance looks right before paying

Even when a payment plan is the ultimate outcome, it’s still worth validating that the IRS amount is accurate—especially if you’ve moved, missed documents, or haven’t filed in multiple years.

If you disagree: respond clearly and support your position

Many notices can be resolved by showing the IRS what it’s missing—often a form, a corrected figure, or documentation that explains a mismatch.

A strong response usually includes:

A short letter referencing the notice number, tax year, and taxpayer name/ID
A direct statement: what you disagree with and why
Copies (not originals) of supporting documents

Deadlines matter. If you need time to gather records, it’s still wise to act quickly and document what you’re doing.

Special situation: you haven’t filed in a couple of years

In Georgia, we see many people who weren’t trying to avoid taxes—they were dealing with a business downturn, a move, family issues, or simply got overwhelmed. If you’re 1–3+ years behind, an IRS notice can be the push that gets everything moving.

A practical way to think about it:

Start with the notice tax year and any year the IRS is actively contacting you about.
Then build a plan to file the remaining missing returns in a sensible order.

Also remember: sometimes people who assume they’ll owe are surprised to learn they’re due a refund for a prior year. But refunds can be subject to filing time limits, so the sooner you get caught up, the more options you usually have.

IRS letter vs. Georgia Department of Revenue letter: why it matters

The IRS and GA DOR are separate agencies, with different portals, processes, and timelines. Confusing one for the other can lead to missed deadlines.

A quick tip: if the letter references Georgia Tax Center or state-specific tax types, you’re likely dealing with GA DOR. If it references CP/LTR codes, federal tax years, and IRS service centers, it’s likely federal.

If you receive letters from both agencies, coordination matters—especially for businesses and self-employed taxpayers where federal and state filings are closely connected.

When it’s time to bring in a professional

Some notices are straightforward. Others aren’t—especially when:

The notice involves multiple tax years
You have unfiled returns
You’re self-employed, have 1099 income, or sold investments/crypto
The IRS is proposing changes you don’t understand
You’ve already responded once and the issue persists

In those situations, the goal isn’t just “reply to a letter.” It’s to resolve the root cause and prevent the same problem from returning next year.

Conclusion

An IRS notice is a signal to act—not to panic. Identify the CP/LTR number, verify the letter is legitimate, and respond by the deadline with the right documentation. For Georgia individuals and businesses who are behind on filing, the fastest path to relief is usually a clear plan: resolve the notice and catch up on the missing returns.
