Can you explain exactly how to get the transcript? I logged into my IRS account but got confused by all the different transcript options. Is it the "Record of Account" or the "Account Transcript" or something else?

You want to request the "Wage and Income Transcript" which shows all information returns filed with your SSN (like W-2s, 1099s, etc.) for the tax year in question. This will show exactly what the IRS has on record. Also request the "Account Transcript" for the specific tax year, which shows actions taken on your account including assessments, payments, and adjustments. These two together will give you the complete picture of what the IRS is seeing versus what you reported.

TurboTax Audit Defense does cover CP2000 notices! I used it last year when I got one. You just need to call them and they'll assign a tax professional to help prepare your response. They won't represent you before the IRS, but they'll help you figure out what documentation to send and review your response letter.

Thank you for this advice - you're right that I should respond directly to this notice rather than assuming they'll eventually process the amendment. Did you have to get tax transcripts to resolve your situation? Someone else mentioned those and I'm not sure if I need them.

Yes, tax transcripts were really helpful in my case. They show exactly what the IRS has in their system versus what you filed. You can request them online through the IRS website or have your accountant get them. The transcript will show if your amended return is in their system and whether your $4k payment was properly applied. The other thing to consider is requesting a formal appeal or audit reconsideration. This creates a separate track for resolving your case rather than just waiting for the amendment to be processed, which can take forever. Your accountant should be familiar with this process. The key is to be proactive rather than reactive - don't just wait for the IRS to figure it out.

This is excellent advice. I'm a tax preparer and see this issue multiple times every tax season. The IRS computers just match document numbers, so if the cost basis isn't properly reported, they'll tax the entire proceeds as gain.

How can you tell which distributions are qualified vs non-qualified? My 1099-DIV has all these different boxes and I'm never sure what they mean.

On your 1099-DIV, qualified dividends will be in Box 1b, while Box 1a shows total ordinary dividends (which includes both qualified and non-qualified). The difference between Box 1a and 1b would be your non-qualified dividends. Capital gain distributions will be in Box 2a. These are the fund's long-term capital gains that get the preferential tax rate. If the fund had to distribute short-term capital gains, those would actually be included in Box 1a as ordinary dividends, not in the capital gains box, which is why it can get confusing!

I've used TurboTax for years with my mutual funds. It works OK if your brokerage provides good 1099s with detailed cost basis info. You can import directly from most major brokerages which helps avoid mistakes. But for older funds where you've been reinvesting for 10+ years, sometimes you need to manually adjust things, which can get complicated in TurboTax.

That's super helpful! I'll check again tomorrow. Did you get any kind of email notification when it was uploaded or did you just happen to check and see it was there?

I didn't get any email notification, I just happened to check and it was there. I know some of my coworkers did get email notifications though, so it seems inconsistent. Might depend on what email preferences you have set up in the HR system. I'd recommend checking once in the morning and once in the evening rather than constantly refreshing. Their system gets really bogged down this time of year with everyone checking for their W2s.

Yep! This happened to me two years ago. My state withholding was completely wrong. I printed what was available and took it to HR, and they had to issue a corrected W2. Took almost 3 weeks to get the fix. I'd recommend comparing your last December paystub (with the year-to-date totals) to your W2 when it arrives to catch any errors early.

Does this change if it's a sole proprietorship though? Since the business income passes through to the business owner's personal return anyway? I'm confused about how this works since technically the money would be taxed on someone's personal return either way.

Great question about sole proprietorships. You're right that the income ultimately flows to someone's personal return, but it matters WHO reports it. The income should flow through the Schedule C of the actual business owner (father-in-law), not OP. Even though it's all "personal income" eventually, the proper reporting chain matters. If reported incorrectly as OP's income, they're being taxed on money they never received or controlled. Plus, the father-in-law's business isn't showing its true income, which creates problems for both parties. The key is getting the income attributed to the correct taxpayer, even if both are individuals in the eyes of the IRS.

The Taxpayer Advocate Service can be amazing but they're extremely backlogged right now. I applied for help in January and didn't hear back until April. They're prioritizing cases with immediate hardship (like impending house foreclosure or can't afford medications). Based on what OP described, they might qualify if the tax bill is causing severe financial hardship, but I'd pursue multiple paths simultaneously rather than waiting on TAS.
