That actually makes me feel better! Do you think it's worth trying to do my own taxes this year with software, or should I just stick with my tax person until my situation gets more stable? Right now I just have one job and some student loans.

With just one job and student loans, you have a perfect situation to try doing it yourself! It's actually the ideal time to learn because your taxes are relatively straightforward but you'll still learn about education credits and student loan interest deductions. I strongly recommend trying it yourself with a good tax software. You can always decide not to submit if you're uncertain and go back to your tax person. But honestly, you'll probably find it much easier than you expect, and you'll learn a ton about taxes that will benefit you for years.

Any specific channels you'd recommend? I've tried looking up tax videos before but couldn't tell which ones were actually giving good info vs just trying to sell something.

What kind of documentation would be considered solid proof for 100% business use? I have a personal vehicle too, so these test cars really are just for product development and demos.

For 100% business use, you'll want a detailed mileage log showing every trip was business-related. This should include dates, starting/ending locations, purpose of trips, and odometer readings. Having a separate personal vehicle helps your case significantly. Keep all maintenance receipts with notes about how they relate to business use. Take photos of the vehicles showing any business branding or modifications specific to your product testing. Also maintain a written business policy stating these vehicles are designated solely for product testing and not authorized for personal use.

Even if the vehicles are fully depreciated, you can still deduct maintenance expenses based on business use percentage. Depreciation is separate from ongoing operating expenses. I have a 12-year-old truck that's fully depreciated but still deduct all the maintenance costs for the business portion of its use.

Thanks for bringing this up - it's possible I didn't actually pay after responding. I sent back the response form agreeing to the amount, but now that I think about it, I don't remember if I included a check or if I was supposed to wait for a payment instruction. That could definitely be the issue. Has anyone here paid after responding to a CP2000? Did you include payment with your response or wait for them to send payment instructions?

You generally have two options: you can include payment with your CP2000 response, or you can wait for the IRS to send you a bill after processing your response. If you chose the second option and they haven't processed your response yet, that's likely why you received the CP3219A. I'd recommend calling the IRS (using one of the methods others suggested to get through) and ask about the status of your case. Tell them you agreed to the CP2000 and want to pay the amount due immediately. They should be able to take your payment over the phone or give you instructions for paying online. Make sure to get a confirmation number for any payment you make.

This happened to me too. My company's stock admin platform reported the sales to my brokerage but the cost basis information didn't transfer correctly. The IRS only saw the proceeds and thought I made way more profit than I actually did. What a mess.

22 Is there a way to check if this happened? I'm not aware of owing anything, but I guess it's possible something slipped through the cracks.

11 You can usually see this on your state's "Where's My Refund" tool - it would say something like "refund offset" or "refund applied to outstanding debt" instead of just "refund issued." You can also call your state's offset program directly - most states have one that handles when refunds are diverted to pay debts. If it just says "refund issued" then it's likely not an offset issue but rather something went wrong with the deposit. Another thing to consider is if you had tax preparation fees taken out of your refund - sometimes this can cause delays or issues with the final deposit.

20 Good point, I'll give my bank a call. Though wouldn't they typically notify you if they were holding a deposit for review?

8 That's interesting. So if I had moved into the house instead of selling my share to my brother, I could have potentially sold it tax-free later? Do you know if the 2-year clock would start from when my dad passed away or would time he spent there count too?

10 The 2-year clock would start when you actually owned the house, so from the time you inherited it. Your father's time living there wouldn't count toward your ownership period. And yes, if you had moved in and lived there for at least 2 years, you could have potentially excluded up to $250,000 of gain when selling. But remember, with inherited property, your basis is stepped up to the fair market value at date of death anyway, so you'd only pay taxes on appreciation that occurred after you inherited it.

11 Good point! I live in California and don't think we have a state inheritance tax, but I'll double check. Does anyone know which states have inheritance taxes?

25 Only six states still have inheritance taxes: Iowa, Kentucky, Maryland, Nebraska, New Jersey, and Pennsylvania. Each state has different rates and exemptions. Some exempt close relatives entirely while others have lower rates for them. If you're in California, you're right that there's no state inheritance tax there. But always good to verify based on where the property was located, not just where you live. The tax typically applies based on where the deceased person lived or where the property is located.
