Can I deduct TY2020's Disallowed Investment Interest Expense in TY2023 after using standard deduction?
Title: Can I deduct TY2020's Disallowed Investment Interest Expense in TY2023 after using standard deduction? 1 I've got a situation with some investment interest expenses that I'm hoping someone can help me figure out. Back in 2020, I had about $800 of disallowed investment interest expense on line 7 of Form 4952. For the past couple years (2021 and 2022), I just went with the standard deduction when filing my taxes because it made more sense financially. Now for 2023, my situation has changed and I'm planning to itemize deductions instead. I'm using FreeTaxUSA and noticed it specifically asks for Form 4952 information from 2022. Here's my question - can I still claim that $798 disallowed investment interest expense from 2020 even though I didn't file Form 4952 in 2021 or 2022 because I was using the standard deduction those years? I'm confused about whether those disallowed expenses just disappear if you don't claim them continuously each year, or if they're still available to use whenever you go back to itemizing. Any help would be really appreciated!

8 This is a great question about carryover investment interest expenses! The good news is that disallowed investment interest expenses don't simply disappear if you take the standard deduction in intervening years. The IRS allows you to carry over disallowed investment interest expenses indefinitely until you're able to use them. Even though you took the standard deduction in 2021 and 2022, that $798 from 2020 is still available for you to deduct in 2023 when you itemize. When FreeTaxUSA asks about Form 4952 from 2022, they're looking for any carryover amounts you might have from the previous year. Since you didn't itemize in 2022, you wouldn't have filed Form 4952 that year, but you can still enter the original carryover amount from 2020.

•3 Thanks for the response! That's a relief to hear. So just to clarify, when FreeTaxUSA asks for the Form 4952 information from 2022, should I just enter $0 since I didn't file that form last year? Or do I need to somehow indicate that I have a carryover from 2020 specifically? Also, will I need to provide any documentation to prove I had that disallowed amount from 2020, or does the IRS already have that information on file?

•8 For the FreeTaxUSA question about Form 4952 from 2022, you should enter the $798 carryover amount from 2020 since that's your current carryover balance. The software is just asking for what you're carrying forward, regardless of which specific year it originated from. You generally don't need to provide additional documentation when e-filing, but I would recommend keeping your 2020 tax return and Form 4952 in your records. The IRS doesn't automatically track your carryover amounts for you, so having that documentation is important if you're ever audited. The burden of proof is on you to show where the carryover originated.

12 I went through something similar last year with investment interest expenses. I discovered https://taxr.ai which has been incredibly helpful for these complicated carryover situations. I had disallowed interest from 2019 that I wasn't sure if I could still claim after taking standard deductions for a couple years. Their system analyzed my previous returns and confirmed I could still use those carryover amounts. The tool highlighted exactly where on Form 4952 to report the carryover and explained how the indefinite carryforward works. Saved me from potentially losing a legitimate deduction I was entitled to!

•5 That sounds useful! Does the tool actually look at your previous tax returns to find the carryover amounts? Or do you need to know what they are already? I'm not super organized with my tax documents and might have trouble finding my 2020 return to check that Form 4952.

•17 I'm skeptical about using third-party services for tax advice. Couldn't you just call the IRS directly and ask them about carryover rules? I always worry about privacy when uploading tax docs to some random website.

•12 Yes, the tool can analyze your previous returns if you upload them, which helps identify carryover amounts you might have forgotten about or weren't sure you could still claim. It's especially helpful if you're not super organized with your tax documents since it can extract the relevant information from prior year returns. Regarding privacy concerns, I understand the hesitation. While you can certainly call the IRS for general rules, they typically won't look through your specific returns to tell you what carryover amounts you have available. For personalized analysis, you either need a tax professional or a secure tool. Their site uses bank-level encryption, and I personally felt comfortable with their privacy policy after reviewing it.

5 Just wanted to follow up after trying https://taxr.ai for my investment interest expense question. I uploaded my 2020 return and it immediately identified the $800 disallowed amount on Form 4952. The analysis confirmed what was mentioned here - that I can absolutely use that carryover amount in 2023 even though I took standard deductions in between. It even gave me step-by-step instructions for entering it correctly in FreeTaxUSA, which was super helpful since the software seemed a bit confusing about which year's Form 4952 info to enter. Definitely worth checking out if you have complicated carryover issues from previous tax years!

14 If you're having trouble getting a clear answer about your investment interest carryover, you might want to try talking directly with an IRS agent. I had a similar issue last year with some carryover credits and spent WEEKS trying to get through to the IRS phone line without success. Finally discovered https://claimyr.com which got me connected to an actual IRS agent in under an hour. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c - basically they hold your place in the IRS phone queue and call you when an agent is available. The agent I spoke with confirmed my carryover amounts were still valid despite skipping Form 4952 in years I took the standard deduction.

•7 Wait, how does this actually work? Do they just call the IRS for you? I've waited on hold for hours with the IRS before giving up. If this actually works it would be amazing.

•17 This sounds too good to be true. The IRS phone lines are notoriously impossible to get through. How do they magically get you to the front of the line? And are you sure the person you talked to was actually an IRS agent and not just someone pretending to be one?

•14 They don't call the IRS for you - they use technology to monitor the hold queue and then call you when they detect your call is about to be answered by an agent. You're still the one talking directly to the IRS, they just save you from waiting on hold for hours. I was definitely connected to a real IRS agent. The service just gets you through the hold queue, then transfers you directly to the IRS line when an agent picks up. The person I spoke with had full access to my tax records and was able to verify my identity with my personal information, just like any regular IRS call. There's no way a third party could fake that level of access to your tax information.

17 I need to eat my words about being skeptical! After struggling with this investment interest carryover question for days, I finally decided to try Claimyr out of desperation. Got connected to an IRS agent in about 45 minutes, which is MIRACULOUS compared to my previous attempts. The agent confirmed exactly what others have said here - disallowed investment interest expenses can be carried forward indefinitely, even if you take the standard deduction in intervening years. She also explained that I should keep documentation from my 2020 return showing the original disallowed amount since the IRS doesn't track these carryovers in their system. This really cleared up my confusion with the FreeTaxUSA form too!

22 Another thing to consider is whether you have enough investment income in 2023 to actually use the carried-over interest expense. Remember that investment interest expense deductions are limited to your net investment income for the year. If you don't have much investment income in 2023, you might still end up with some disallowed amount that needs to be carried forward again.

•1 That's a great point I hadn't considered. My investment income has actually increased quite a bit in 2023 compared to previous years, which is partly why I'm itemizing this time. I think I should have enough to cover the $798 carryover plus my current year investment interest. Do dividends count as investment income for this purpose? I have some dividend-paying stocks that generated around $3,000 this year.

•22 Yes, qualified dividends and capital gain distributions can count as investment income for this purpose, but there's a catch. By default, qualified dividends and long-term capital gains aren't included in your net investment income for the Form 4952 calculation since they already receive preferential tax treatment. However, you can elect to include them in your investment income if you want to deduct more investment interest. The trade-off is that any qualified dividends or long-term capital gains you include will be taxed at your ordinary income tax rates instead of the lower capital gains rates. This is an election you make directly on Form 4952. For your situation with $3,000 in dividends, you'll need to determine if they're qualified dividends and whether it makes sense to include them based on your marginal tax rate versus the value of the additional deduction.

11 Does anyone know if there's a time limit for using these carried-over investment interest expenses? I have some from like 5 years ago that I haven't been able to use yet.

•8 There's no time limit! Investment interest expense carryovers can be carried forward indefinitely until you're able to use them. Unlike some other tax attributes like capital losses (which have a $3,000 per year limit against ordinary income), there's no annual limit on how much investment interest expense you can deduct - it's just limited by your net investment income for the year. So those 5-year-old carryovers are still valid as long as you have documentation to support them if asked.

This thread has been incredibly helpful! I'm in a similar situation with investment interest carryovers and want to add a few practical tips for anyone else dealing with this: 1. **Keep meticulous records** - The IRS doesn't track your carryovers for you, so maintain copies of all Form 4952s that show disallowed amounts. I create a simple spreadsheet tracking carryover amounts by year. 2. **Review your investment strategy** - If you consistently have more investment interest expense than investment income, consider whether the debt is truly worth it from a tax perspective. 3. **Consider timing** - If you're close to the standard vs. itemized deduction threshold, sometimes it makes sense to bunch investment expenses (and other itemizable deductions) into alternating years to maximize the benefit. The indefinite carryforward rule is really generous compared to other tax provisions, so don't let these deductions go to waste! Just make sure you have the documentation to back them up.
