I just went through this exact situation last month with my SSDI backpay from 2022-2023 that I received in 2024. The Publication 915 worksheets are absolutely brutal to figure out on your own! I ended up using TaxAct Premium after reading recommendations here and elsewhere, and it really did handle everything automatically. The key thing I learned is that you need your SSA-1099 form that shows the breakdown of which years your backpay covers - without that, you're basically guessing at the calculations. One thing that helped me understand the process better: that negative number you're getting on worksheet 2, line 21 is actually pretty common with SSDI backpay. It typically means your income in those prior years was low enough that the Social Security benefits wouldn't have been taxable anyway. So you're not doing anything wrong! The lump sum election calculation can save you significant money compared to just treating it all as current year income. In my case, it saved me about $800 in taxes. Definitely worth getting right, and the automated software takes all the guesswork out of it.
This is really helpful to hear from someone who just went through this! I'm in a similar situation and that $800 savings you mentioned definitely makes the software worth it. Quick question - did TaxAct automatically detect that you had SSDI backpay when you uploaded your SSA-1099, or did you have to navigate to a specific section to trigger the Publication 915 calculations? I want to make sure I don't miss anything when I set it up.
TaxAct automatically detected it when I entered my SSA-1099! As soon as I input the form, it prompted me with a question asking if any of the Social Security benefits were from prior years. When I said yes, it opened up the whole lump sum election interview process. The software walked me through each year the backpay covered and asked for my income information from those years (which I had to pull from my old tax returns). Then it did all the Publication 915 calculations behind the scenes and showed me the comparison - how much tax I'd owe treating it as current year income vs. using the lump sum election method. Just make sure you have your prior years' tax returns handy when you start the process, because you'll need your AGI and other income info from those years to complete the calculations accurately.
I'm dealing with a similar SSDI backpay situation and this thread has been incredibly helpful! I received backpay covering 2022-2023 that hit my account in 2024, and I was completely overwhelmed trying to figure out Publication 915. Based on all the recommendations here, I decided to try TaxAct Premium and it really did make the process much smoother. Like others mentioned, it automatically detected the lump sum situation when I entered my SSA-1099 and walked me through the calculations step by step. One thing I wanted to add that I learned from my tax preparer friend - if you're still getting negative numbers on the worksheets and it seems wrong, double-check that you're using the correct "base amount" from the tables in Publication 915. The base amount depends on your filing status, and using the wrong one can throw off all your calculations. For single filers it's $25,000, for married filing jointly it's $32,000, and for married filing separately it's $0 if you lived with your spouse at any time during the year. Also, don't forget that if you do end up owing additional tax because of the lump sum election, you might be able to spread those payments out rather than paying it all at once. The IRS has provisions for this in certain situations involving Social Security backpay.
This is such valuable information about the base amounts! I think that might be exactly what was tripping me up. I'm married filing jointly but I think I was accidentally using the single filer base amount of $25,000 instead of $32,000. That could definitely explain why my calculations seemed off. The point about spreading out payments is really interesting too - I had no idea that was an option with SSDI backpay situations. Do you happen to know if there's a specific form or process for requesting that payment arrangement, or is it something you have to call the IRS about directly? Thanks for sharing your experience with TaxAct - it sounds like that's definitely the way to go rather than trying to muddle through the manual worksheets!
Has anyone here considered the qualified business income deduction (Section 199A) when running construction through an LLC? I think you can get up to 20% off your business income that way, but I'm not sure if one-off construction projects qualify.
Yes, the QBI deduction could potentially apply here. If your LLC is making a profit from the construction and sale, and it qualifies as a business rather than an investment activity, you might be eligible for that 20% deduction. However, there are income thresholds and other limitations.
Great question about the LLC structure! I went through a similar decision process last year when I built a spec home. Here's what I learned: From a pure tax perspective, if this is truly a one-time project, the LLC won't change much - you'll still report everything on Schedule C either way. However, I ended up forming an LLC and I'm glad I did for several reasons: 1. **Clean separation of expenses**: Having dedicated business accounts made tracking deductions so much easier. When you're dealing with dozens of contractors and material purchases, this becomes invaluable. 2. **Professional credibility**: Contractors and suppliers took me more seriously when I could pay from a business account and provide an LLC business license number. 3. **Future flexibility**: Even though I planned it as a one-off, I ended up enjoying the process and am now looking at my second project. The LLC is already established. 4. **Audit protection**: If the IRS ever questions your business vs. hobby status, having formal business structure from day one strengthens your position. The setup costs are minimal (usually $100-300 depending on your state), and maintaining it is pretty straightforward. For the peace of mind and organization benefits alone, I'd recommend going the LLC route. One tip: Make sure you get an EIN and open business bank accounts right away. Don't commingle personal and business funds - that's the fastest way to lose your liability protection.
This is really helpful advice! I'm curious about the EIN requirement - is that necessary even for a single-member LLC? I was under the impression that you could just use your SSN for tax purposes. Also, when you mention "audit protection" regarding business vs. hobby status, what specific documentation did you keep to support the business classification?
I switched from TaxAct to FreeTaxUSA this year after having similar login problems. Their interface is way more reliable and honestly easier to use. Plus it's cheaper for most filing situations. Might be worth looking into for next year if you keep having issues.
I had the exact same issue with TaxAct last week! The login loop is so frustrating. What finally worked for me was completely logging out of all Google/Microsoft accounts in my browser first, then clearing all site data for TaxAct specifically (not just cookies), and then trying again. If you're still stuck, you can also try accessing TaxAct through their mobile app instead of the website - sometimes that bypasses whatever browser-specific issues they're having. The mobile app saved my progress when the website wouldn't let me back in. Really hoping they fix these server issues soon. It's ridiculous that we have to jump through so many hoops just to file our taxes!
Thanks for sharing that detailed solution! I'm curious - when you say "clearing all site data for TaxAct specifically," how exactly do you do that? Is that different from just clearing cookies? I'm not super tech-savvy and want to make sure I'm doing it right if I run into this issue again. Also, did the mobile app have all the same features as the desktop version? I have some complex business deductions that I worry might be harder to navigate on a smaller screen.
Does anyone know if this will affect the way the conversion is taxed? My understanding is that with in-plan Roth conversions, you're supposed to pay tax on the pre-tax portion that gets converted, but not on any after-tax contributions. Would the wrong code change how the IRS calculates the taxable amount?
The code itself shouldn't change the taxability - that's determined by the amounts reported in other boxes on the 1099-R. Box 1 shows the total distribution, and Box 2a shows the taxable amount. If you made after-tax contributions that were converted, Box 5 should show those as the employee contribution amount, which reduces the taxable portion. Double-check those amounts to make sure they're correct, regardless of the code in Box 7!
I've dealt with this exact issue before with my solo 401(k). You're absolutely correct that code G should be used for in-plan Roth conversions, not code 2. Code 2 is specifically for early distributions from IRAs with exceptions. Here's what I learned from my experience: First, definitely contact your plan administrator ASAP to request a corrected 1099-R. Many can turn these around quickly since it's just a code correction. Second, if they can't get you a corrected form before your filing deadline, you can still file your return and include a brief statement explaining that the transaction was an in-plan Roth conversion within your 401(k), not an IRA distribution. The key thing is to make sure the dollar amounts in the other boxes are correct - Box 1 (gross distribution), Box 2a (taxable amount), and Box 5 (employee contributions). The wrong code is annoying but won't change your actual tax liability as long as those amounts are right. Keep documentation of your request to the plan administrator. I had to push mine pretty hard - they initially said "code 2 is fine" but eventually admitted they were using outdated guidance and issued the correction.
This is really helpful! I'm dealing with a similar situation and wondering - when you say "push them pretty hard," what exactly did you have to do? Did you have to cite specific IRS regulations or publications? My plan administrator is being pretty stubborn about this and keeps insisting that code 2 is correct for any Roth conversion, even though I know that's not right for in-plan conversions within the same 401k. Also, did you end up filing on time or did you have to request an extension while waiting for the corrected form?

LPT: don't forget that while most of the military moving expenses are covered, you can still deduct anything that wasn't reimbursed! This includes things like extra weight charges if you were over your allowance, temporary storage beyond what the military covered, and miscellaneous moving-related expenses. The key with Form 3903 is that you can only deduct costs the military didn't reimburse you for. So document everything carefully, especially for an OCONUS move!

ā¢Thanks for the tip! We definitely have some other expenses beyond just the pet transportation that weren't covered. Do you know if we can claim mileage for driving our own vehicle to the port for shipping? And what about temporary lodging expenses beyond what DLA covered?

Based on all the experiences shared here, it seems like the consensus is that pet transportation costs are generally not deductible on Form 3903, even for military PCS moves. While it's frustrating since these costs can be substantial for overseas moves, the IRS appears to consistently treat pets as personal expenses rather than household goods. For your situation with Max's transportation to England, I'd recommend focusing on documenting all the other non-reimbursed moving expenses you'll have. Things like excess weight charges, additional travel costs not covered by your per diem, or any storage fees beyond what the military covers can add up and are clearly deductible. If you do decide to claim the pet transportation despite the risks, make sure you have thorough documentation and understand you might need to defend it if audited. But given the experiences shared by Giovanni and the JAG advice Fatima mentioned, it might not be worth the potential hassle. Good luck with your move to England! The overseas assignments are amazing experiences even if the PCS process is stressful.
