I've been dealing with this same dilemma for years! What I've learned is that it really depends on your specific situation and risk tolerance. If you have relatively straightforward investments (basic ETFs, individual stocks, simple mutual funds) from major brokers, the corrections are often minor - maybe a few dollars difference in qualified dividends or small adjustments to capital gains distributions. In these cases, I've started filing early because the amendments usually aren't worth the hassle. However, if you have more complex investments or you know from experience that your specific brokers tend to send significant corrections, waiting might be worth it. I keep a simple spreadsheet now tracking when I get corrections each year and how much they typically change my tax liability - this has helped me make better decisions about when to file. One thing that's helped me sleep better at night is setting a personal threshold: if I know corrections historically change my refund by less than $50, I file early. If they're usually more significant, I wait until mid-March. This takes the guesswork out of it and gives me a clear decision framework each year.

I'm in a very similar boat with Fidelity and have been going through this exact same waiting game for the past few years! What I've learned is that their corrections typically involve reclassifications of dividend income or adjustments to cost basis calculations that can actually be pretty significant. Last year I decided to wait until March 15th as my personal cutoff date, and sure enough, got a corrected 1099 on March 12th that changed my refund by about $300. The correction had to do with some foreign tax credits that weren't properly calculated on the original form. My strategy now is to use the first few weeks after getting my initial 1099s to organize everything else - gather all my other tax documents, review deductions, maybe even prepare the return in tax software but not file it yet. That way when I do get the final forms (corrected or not), I can file immediately. It's definitely frustrating to wait when you want that refund, but I've found that the peace of mind of not having to deal with amendments is worth the extra few weeks. Plus, if you're getting a refund, the IRS isn't charging you interest for filing later in the season anyway.

Has anyone used TurboTax for reporting excess deferrals? I'm in a similar situation and wondering if it handles this properly or if I need to manually override something.

I went through this exact same situation last year and can confirm you're handling it correctly! The key thing to remember is that excess deferrals are treated differently than regular 401k contributions for tax purposes. Just to add to what others have said - when you report the $2,600 on line 1h of your 2024 return, you're essentially treating it as regular taxable income since it exceeded the contribution limit. This prevents you from getting an improper tax deduction on money you weren't supposed to contribute in the first place. One thing I wish someone had told me: keep really good records of all this. Save your correspondence with Fidelity about the excess distribution, any statements showing the amounts, and a copy of how you reported it on your 2024 return. When you get those 1099-Rs in 2026, you'll want to cross-reference everything to make sure it all matches up correctly. The timing is definitely confusing, but you're doing it right by addressing it now rather than waiting. Good catch on getting the excess withdrawn before the April deadline!

For those interested in the technical details, I believe the specific issue is in how Worksheet 2a handles the refund allocation. Looking at the latest version, Step 5 has you multiply your refund by a fraction (state/local income tax deducted ÷ total state/local income tax paid). This seems correct conceptually. However, the problem may be in how this interacts with other types of SALT deductions (like property taxes) when you've hit the overall $10K cap. The worksheet doesn't seem to properly account for situations where you've claimed multiple types of SALT deductions that together hit the cap. Has anyone contacted the IRS about this potential issue? It seems like something they should clarify or correct in a future revision of Publication 525.

This is a great discussion that highlights a real problem many taxpayers are facing. I've been dealing with this exact worksheet issue for my 2023 return and it's incredibly frustrating that the IRS hasn't provided clearer guidance. What I found helpful was creating my own calculation spreadsheet that follows the tax benefit rule more precisely. I calculated what percentage of my total state/local tax payments actually provided a federal tax benefit (considering the SALT cap), then applied that same percentage to my refund to determine the taxable portion. For example, if I paid $12,000 in state income tax and $8,000 in property tax ($20,000 total) but could only deduct $10,000 due to the SALT cap, then only 50% of my payments provided a tax benefit. So if I received a $2,000 state income tax refund, only 50% ($1,000) should be taxable income. This approach seems more aligned with the underlying tax principle than blindly following a worksheet that wasn't designed for post-TCJA scenarios. I'm planning to attach a brief explanation with my return showing this calculation method. Has anyone else taken a similar approach, and if so, have you had any issues with the IRS accepting it?

Does anyone use tax software instead of an accountant? I'm using TurboTax Business for my Schedule C and wonder if the subscription cost is handled the same way. Would I deduct my TurboTax subscription cost on this year's return or next year's?

Great question! I went through this same confusion when I started my consulting business. The key principle everyone's mentioned is correct - you deduct tax prep fees in the year you actually pay them, regardless of which tax year the return covers. One thing I'd add that hasn't been mentioned yet is to keep really good documentation of when you pay these fees. I create a simple spreadsheet each year tracking the date, amount, and what the payment covers (2023 tax prep, estimated payment penalties, etc.). This has been super helpful during tax time and gives me confidence I'm being consistent year over year. Also, if your accountant offers payment plans or lets you pay in installments, each payment gets deducted in the year you make it. So if you paid $400 in December 2023 and $450 in March 2024 for the same tax return, you'd split the deduction across those two tax years accordingly.

This is a really complex situation that depends heavily on which depreciation method you've been using! Since you mentioned tracking mileage meticulously, I'm curious - have you been using the standard mileage deduction or actual expenses (including depreciation) for your current vehicle? If you've been using standard mileage, your tax situation when selling will be quite different from what some others have described. The standard mileage rate includes a depreciation component (around 27 cents per mile in recent years), so your adjusted basis would be your original cost minus the total depreciation embedded in all those standard mileage deductions over 6 years. However, if you've been claiming actual depreciation and the car is fully depreciated as you mentioned, then yes - you're looking at significant depreciation recapture taxed as ordinary income when you sell. For the new $38,000 vehicle, switching to actual expenses could be beneficial since you'd be able to claim bonus depreciation or Section 179 expensing. Just remember that once you switch to actual expenses for a vehicle, you can't go back to standard mileage for that same car. Given the amounts involved here, I'd strongly recommend consulting with a tax professional before making the purchase. The timing of when you sell the old car versus buy the new one, plus which depreciation method you choose going forward, could save or cost you thousands in taxes.

You're absolutely on the right track with your calculation! Yes, with standard mileage deduction over 6 years, your adjusted basis would be significantly higher than someone who fully depreciated their vehicle using actual expenses, which means a much smaller taxable gain. One additional consideration I'd mention - when you switch to actual expenses for your new vehicle, make sure you're prepared for the record-keeping requirements. You'll need to track not just mileage, but also maintenance, repairs, insurance, registration fees, and all other vehicle-related expenses. It's more work than standard mileage, but with a $38,000 vehicle and current bonus depreciation rules, the tax savings should make it worthwhile. Also, don't forget that your business use percentage (80% in your case) applies to all these deductions. So on that $38,000 vehicle, you'd be looking at bonus depreciation on about $30,400 of the purchase price, which could provide substantial first-year tax savings to offset your gain from the sale. The timing strategy others mentioned is spot-on too - selling early in the year and purchasing late in the year maximizes your depreciation deduction in the year of sale. Good luck with the upgrade!
