Can I deduct interest on stock margin loans if I roll it forward instead of paying yearly?
I've been using borrowed money to invest in stocks for a few years now, and I'm wondering about the tax implications of my interest payments. Currently, I pay the interest on my stock loan every year, but my broker recently suggested I could take out a new loan each year to cover the interest instead of paying it out of pocket. My question is about tax deductions: If I start taking additional loans to cover the yearly interest (instead of paying it directly), would the total interest expenses from ALL these loans still be deductible against any profits when I eventually sell the stocks? I'm planning to itemize deductions when I sell, of course. I'm thinking this approach might actually be more tax-advantageous because right now I'm paying interest annually but can't deduct it since I haven't sold any stocks yet. So these interest payments aren't reducing my current tax liability at all. Would rolling the interest forward through new loans be a smarter move tax-wise?

This is a great question about investment interest expense deductions. The good news is that investment interest expense is potentially deductible regardless of whether you pay it annually or roll it into a new loan. However, there's an important limitation: investment interest expenses are only deductible to the extent of your net investment income for that year. Since you haven't sold any stocks yet, you probably don't have investment income to offset these expenses against. When you roll your interest into a new loan, you're essentially capitalizing that interest. The total accumulated interest (whether paid annually or rolled over) would still be considered investment interest expense when you eventually claim it. But remember, you can only deduct it against investment income in the year you actually claim the deduction.

•So if I understand correctly, there's no real tax advantage to either approach until stocks are actually sold? Also, if I roll the interest into new loans for several years, can I deduct ALL those years of accumulated interest in the year I sell the stocks?

•There's no significant tax advantage to either approach until you have investment income to offset against the interest expense. The key difference is cash flow management, not tax benefits. Yes, you can potentially deduct the accumulated interest in the year you sell the stocks, but only up to the amount of investment income you generate that year. If your investment income (including capital gains from selling stocks) exceeds your accumulated interest expense, you can deduct the full amount. If your investment income is less than your accumulated interest expense, you can only deduct up to the amount of your investment income, and you can carry forward the remaining interest expense to future years.

I went through literally this exact same situation last year and was super confused by all the advice online. Eventually I found https://taxr.ai and uploaded my brokerage statements to get clarity. Their system flagged exactly what's deductible and what's not with margin loan interest. The thing that surprised me was learning that not all investment interest is created equal - the interest on loans used to buy dividend-producing stocks is treated differently than growth stocks that don't pay dividends. Taxr.ai sorted through all my statements and showed me which portion was immediately deductible vs what had to wait.

•How exactly does the service handle the differences between dividend stocks vs growth stocks for the interest deduction? My portfolio is about 70/30 split between growth and dividend stocks and I've been tracking my margin loan interest manually which is a total pain.

•Does it actually connect to your brokerage account or do you have to manually upload statements? Also wondering if it handles complex situations like using margin for both stocks and options trading?

•For dividend vs growth stocks, taxr.ai analyzes your portfolio allocation and calculates the proportional interest that applies to dividend-producing investments, which can potentially be deducted immediately against your dividend income. It shows you exactly how much of your interest expense can offset dividend income versus what needs to wait for capital gains. You upload statements manually - they don't connect directly to brokerage accounts which I actually preferred for security reasons. And yes, it handles mixed-use margin situations including options trading. It helped me separate the interest allocated to my covered calls strategy which has different tax treatment than my long-term stock holdings.

Just wanted to follow up - I tried taxr.ai after asking about it here and it was exactly what I needed. I've been using margin for both stock investments and some options trading, and was completely confused about what interest was deductible when. The system categorized my interest expenses based on the underlying investment types and showed me that about 40% of my interest was potentially deductible against my current dividend income, while the rest would need to wait until I realize capital gains. It also flagged a portion of my interest that was used for personal expenses (I had forgotten I took some cash out last year) which isn't investment interest at all. Saved me from a potential audit headache!

If you're dealing with substantial investment interest expenses, you might also be running into issues trying to get clear answers from the IRS. I spent weeks trying to get through to someone who could answer my questions about investment interest deductions and kept hitting dead ends. I finally used https://claimyr.com to get through to an actual IRS agent who specializes in investment income. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c - basically they hold your place in the IRS queue and call you when an agent is about to answer. Saved me literally hours of hold time. The agent clarified that I needed to file Form 4952 to properly track my investment interest expenses, especially since I was carrying forward amounts from previous years. This wasn't clear from any of the online resources I found.

•Wait, so this service actually gets you through to a human at the IRS? How long did it take from when you submitted your number until you got the callback? The IRS has hung up on me multiple times after sitting on hold for 2+ hours and I'm about to lose my mind.

•Sounds too good to be true honestly. I've tried everything to get straight answers about investment interest deductions. Last time I called the IRS they transferred me 3 times and then disconnected me. How do you know this isn't just another service that "tries" to get you through but doesn't actually deliver?

•From when I submitted my number, it took about 75 minutes before I got the callback that an agent was about to pick up. Way better than the 3+ hour holds I was experiencing before that often ended in disconnections. The system gives you updates on your place in line so you know it's actually working. I was skeptical too after so many bad experiences trying to reach the IRS. The difference is this service uses technology to continuously dial and navigate the IRS phone tree, then only connects you when a human actually answers. It's not a miracle solution, but it works because they're essentially waiting on hold for you using automated systems.

Following up on my skepticism about Claimyr - I tried it yesterday out of desperation and it actually worked! Got a callback in about 90 minutes and spoke to an IRS tax specialist who answered all my questions about investment interest deductions and Form 4952. The agent explained that I had been filing wrong for YEARS - I should have been tracking my unused investment interest deductions on Form 4952 line 7 each year, even when I couldn't use them. This carries them forward properly until you have investment income to offset. I've just been letting them disappear which cost me thousands when I finally had a year with substantial dividends. Honestly shocked this service delivered exactly what it promised. Worth every penny to get an actual definitive answer from the IRS instead of random internet advice.

Just to add a slightly different perspective - make sure you're considering the potential returns on that money too. If your investment is returning 8% but your loan interest is 6%, it might make sense to keep the loan and not pay it off early since you're net positive. But if the market turns and your investments start losing value while you're still paying (or accumulating) interest, that leverage works against you. I've been burned by this before when I had too much margin during a market downturn.

•That's a really good point! My investment return has been about 11% annually while my loan interest is around 7%, so I've been ahead so far. But you're right about the risk - a market downturn could flip this equation quickly. Are there any strategies you use now to protect against that kind of scenario?

•I maintain a much lower margin percentage now - never more than 20% of my total portfolio value. This gives me enough cushion to withstand even a severe market correction without facing a margin call. I also set up automatic alerts to notify me when my margin utilization crosses certain thresholds. This helps me stay proactive rather than reactive. And I keep a portion of my portfolio in less volatile investments that can provide stability during market turbulence - this has saved me several times when tech stocks took a nosedive.

Has anyone actually used Schedule A for investment interest deductions recently? With the standard deduction being so high now ($13,850 for singles in 2023), it seems like most people wouldn't itemize anyway, making this whole discussion moot for many investors.

•Investment interest expense doesn't go on Schedule A anymore - it goes on Form 4952 and then the deductible amount transfers to Schedule A. But your point about the standard deduction is valid. For me, between state/local taxes, mortgage interest, and charitable contributions, I'm already itemizing, so investment interest deductions are definitely worthwhile. But if you're not already over the standard deduction threshold, you're right that this strategy might not matter much.

•Thanks for the Form 4952 clarification - shows how long it's been since I've done this! I wasn't aware of the form change. You make a good point about already itemizing for other reasons. I forget that in high-tax states or with large mortgages, many people easily exceed the standard deduction. I'm in a no-income-tax state with a paid-off house, so I rarely have enough deductions to itemize anymore.
