Just a warning based on my experience - watch out for Form 8832 vs Form 2553 confusion! My accountant filed the wrong form for my conversion and it messed up the timing of everything. Make sure you're using Form 2553 specifically for the S election. I ended up with an extra year as a C-corp because of this mistake and it cost me thousands in corporate taxes I could have avoided.

Something nobody's mentioned is the reasonable compensation issue after you convert. The IRS really scrutinizes S-corps that don't pay reasonable salaries to owner-employees. Since you didn't take any salary in 2023 as a C-corp, make sure you establish a reasonable salary for yourself in 2024 as an S-corp. The IRS loves to audit S-corps with owners taking all profit as distributions and little/no salary to avoid payroll taxes.

Has anyone used TurboTax to report this kind of situation? I have a similar issue with my own annuity and wondering if the software handles it correctly or if I need to override something.

I went through this exact same situation with my grandfather's annuity last year! The 1099-R showed the full distribution as taxable even though he'd purchased it with after-tax dollars back in 2010. What really helped us was getting his original annuity contract and any statements from when he made the purchase. The insurance company had changed hands twice over the years, which is why they didn't have his basis information. We ended up using the Simplified Method worksheet that others mentioned here, and it made a huge difference - about 70% of his monthly payments were actually return of principal. One thing I'd recommend is keeping really detailed records of these calculations because you'll need to use the same exclusion ratio every year until the full investment is recovered. Also, if your mother-in-law ever needs to prove the calculation to the IRS, having that original purchase documentation will be crucial. The good news is you definitely don't need a corrected 1099-R from the company. The IRS expects taxpayers to calculate the correct taxable amount in situations like this where the issuer doesn't have complete basis information.

Did you file the Form 1041 (final estate tax return)? This is different from your mom's personal final 1040. A lot of people don't realize they need to file this separate form for the estate itself, especially if there was any income to the estate after death (like interest, dividends, etc).

I went through something very similar with my father's estate two years ago. The stress and confusion you're feeling is completely normal - these IRS notices can be incredibly overwhelming, especially when you thought everything was properly handled. A few important points to keep in mind: 1. You are likely NOT personally liable for your mother's tax debts. As others mentioned, this depends on whether the notice is addressed to you personally or to "The Estate of [Mother's Name]." 2. The fact that you distributed assets after paying known debts and expenses doesn't necessarily create personal liability, especially if you had no knowledge of additional tax obligations at the time. 3. Document everything! Keep copies of all correspondence, your mother's final tax return, death certificate, and any estate settlement documents. One thing I learned is that the IRS often has incomplete information when they send these notices. Sometimes they're missing forms that were actually filed, or they have outdated address information that caused notices to go to the wrong place initially. Don't let this consume you - there are solutions, and many of these situations get resolved once you provide the proper documentation. The key is responding promptly and getting the right information to the right people at the IRS.

Another approach worth considering is a Section 83(b) election if your company allows early exercise of options. This lets you exercise unvested options and start the holding period for long-term capital gains treatment without triggering as much AMT exposure.

Don't forget about the possibility of an AMT credit! If you do end up paying AMT from exercising ISOs, you can potentially recover that as a credit in future years when your regular tax exceeds your AMT. Worth factoring into your long-term planning.

Has anyone else had trouble with their accountant understanding Section 179 for vehicle upgrades? Mine insists that once you claim the deduction on a vehicle, any future upgrades have to be depreciated normally. I'm pretty sure he's wrong based on what everyone is saying here...

I've been through this exact situation with my electrical contracting business. The key thing to understand is that each capital improvement is treated as a separate asset for Section 179 purposes. So yes, you can claim Section 179 on those truck upgrades even though you already used it for the original vehicle purchase in 2023. However, be very careful about the business use tracking. You'll need to maintain separate records for each asset - the original truck and each major upgrade. If your business use drops below 50% for any individual asset during its recovery period, you'll face recapture on that specific item. One tip that saved me a lot of headaches: take detailed photos and keep receipts for everything. The IRS will want to see that these are legitimate capital improvements that add functionality or value, not just regular maintenance. Your crane attachment and utility bed sound like they'd easily qualify, but document everything properly. Also, consider the timing carefully. With bonus depreciation dropping to 40% in 2025, you might want to accelerate some purchases into 2024 if possible to take advantage of the higher 60% rate this year.
