What's actually happening.
An IRS letter just landed in your mailbox. The number on the corner (CP2000, CP2501, LT11, etc.) means specific things, and the deadline matters. Most people freeze. The wrong response — or no response — costs more than the right one. Ignoring it is almost always the worst option. The right letter, sent certified mail, shows you're engaged and stops the clock on escalation.
What we draft.
Re: Response to CP2000 Notice — Tax Year 2023 Notice Date: March 18, 2026 | SSN: [REDACTED] I am writing in response to the CP2000 notice referenced above. I partially agree with the proposed changes and submit the following documentation and corrections under IRC § 6213. The notice proposes an increase of $4,120 in tax for unreported income. I agree with $1,840 of this adjustment. The remaining $2,280 reflects a 1099-B reported without cost basis — the cost basis for these securities was $6,750, reducing the capital gain to zero. I enclose Form 8949 and brokerage cost basis records...

Laws we cite.
We ground every letter in real statutes and regulations. Here's what applies to your situation:
IRC § 6213 Notice of deficiency — your right to petition the Tax Court within 90 days of receiving a deficiency notice.
IRC § 6320/6330 Collection Due Process — right to a CDP hearing before IRS levies your wages, bank account, or property.
IRS Publication 1 Your Rights as a Taxpayer — foundational rights document the IRS must honor.
IRC § 6404 Abatement of interest and penalties — grounds for requesting penalty relief including first-time abatement.
Who this isn't for.
We're honest about our limits. FightThis may not be right if:
- The amount in dispute exceeds $10,000 — you should have a CPA or tax attorney involved.
- You face potential criminal tax charges — stop and hire a tax attorney immediately.
- The notice is about an ongoing audit — audit representation is a different service.
- You've already received a Final Notice of Intent to Levy — the window is tight; call the IRS Taxpayer Advocate Service (1-877-777-4778) today.
If your situation is high-stakes, please find a local attorney. Many state bars have free or low-cost referral services.
Common questions.
What does my CP2000 notice mean?
A CP2000 means the IRS received income information from a third party (employer, bank, broker) that doesn't match your return. It's not a final assessment — it's a proposed change. You can agree, disagree, or partially disagree.
Do I need to respond?
Always respond by the deadline on the notice, even if just to say you need more time. Silence is treated as agreement with the IRS's proposed changes.
What's first-time penalty abatement?
If you've had a clean compliance history for the past three years, the IRS will typically waive failure-to-pay or failure-to-file penalties under IRC § 6404. FightThis can include this request in your response.
What if I agree with everything?
We can still draft a clean, professional response that confirms agreement and arranges payment — which prevents additional notices and stops interest from compounding.
Is this letter sent to the IRS or the Tax Court?
Most responses go directly to the IRS address on the notice. If you receive a Statutory Notice of Deficiency and want to petition Tax Court, that's a different (more formal) process.
Can I ask for more time?
Yes. Most notices allow you to request a 30–60 day extension. Our letter can include this request with a reason.
We mail it for you
The IRS requires certified mail with return receipt for most formal responses. We handle the entire certified mailing process — including the PS Form 3811 return receipt.
