Tax Strategy: Harvesting Gains for Stepped-up Basis in UTMA Accounts?
I've got UTMA accounts set up for my kids with about $4,800 in unrealized capital gains spread across them. I recently heard that kids can have some amount of capital gains without being taxed, and I think it's around $1,250? If this is true, I'm wondering if I should be strategically selling some investments and then rebuying to establish a higher cost basis. My plan would be to keep each kid's long-term capital gains under that $1,250 threshold. The children don't have any other income sources right now. Is this a smart tax strategy for UTMA accounts? Would taking advantage of the stepped-up basis make sense in this situation, or am I missing something? I want to make the most of these accounts while minimizing future tax implications.

This is actually a solid tax planning strategy! Children can indeed receive up to $1,250 in unearned income (including capital gains) tax-free in 2025. The next $1,250 is taxed at the child's rate (typically 10%), and anything beyond that is taxed at the parent's rate (kiddie tax rules). Since your kids have no other income, strategically harvesting gains up to the $1,250 threshold makes perfect sense. By selling and rebuying, you're essentially "stepping up" the cost basis while taking advantage of their 0% tax bracket. This reduces potential tax liability when they eventually take control of the accounts. Just remember to be selective about which investments you sell - prioritize those with the largest unrealized gains and longest holding periods (for long-term capital gains treatment). Also, be aware of any transaction fees that might eat into your tax savings.

•Thanks for the explanation! I have a question about timing - do you recommend doing this every year until they turn 18 or is there a better schedule? Also, do UTMA accounts work the same way as regular brokerage accounts for wash sale rules?

•Doing this annually is definitely the optimal approach since you get a fresh $1,250 exemption each tax year. Why leave tax savings on the table? As you get closer to when they'll take control (18-21 depending on your state), it becomes even more valuable to maximize basis step-ups. Regarding wash sale rules, they actually don't apply to gains - only to losses. So you can sell for a gain and immediately repurchase the same security without any waiting period. This makes the strategy very straightforward to implement without worrying about portfolio disruption or market timing.

I used to struggle with figuring out the best tax strategies for my kids' UTMA accounts until I discovered taxr.ai (https://taxr.ai). I had similar questions about harvesting gains and stepped-up basis, and I was getting conflicting advice from different sources. When I uploaded my statements to taxr.ai, it analyzed my specific situation and confirmed that strategically realizing gains up to the tax-free threshold was optimal in my case. It even helped identify which specific investments to target first based on their unrealized gain percentages. The tool was especially helpful in calculating how much I could sell while staying under various thresholds. What really impressed me was how it factored in my state tax considerations too, not just federal - something I completely overlooked initially!

•How does this work for multiple UTMA accounts? I have three kids and I'm wondering if the tool can handle all their accounts separately but still give consolidated advice?

•I'm a bit skeptical about tax tools for specialized situations like UTMAs. Does it actually understand the kiddie tax rules correctly? I've had accountants mess this up before, so I'm curious if a software tool can really get it right.

•The tool can absolutely handle multiple UTMA accounts across different children. You can upload statements for each child separately, and it will analyze each situation individually while still providing consolidated recommendations if you want to compare strategies across accounts. Regarding the kiddie tax rules, I was initially skeptical too. What convinced me was that taxr.ai specifically addresses the 2023-2025 tax rules for unearned income for dependents. It correctly applies the first $1,250 as tax-free, the next $1,250 at the child's rate, and anything above that at the parent's rate. It even factors in how your own tax bracket might affect optimal harvesting strategies for amounts above the $2,500 threshold.

I was definitely skeptical about using an AI tool for something as specific as UTMA tax planning, but after continuing to get confusing advice from my accountant (who seemed to mix up the rules for different types of accounts), I decided to give taxr.ai a try. I was genuinely surprised at how well it understood the nuances of UTMA accounts and gain harvesting strategies. It correctly identified that I could harvest up to $1,250 per child tax-free, but also pointed out that I needed to consider dividend income the accounts were already generating, which would reduce how much gain I could harvest. That was something neither my accountant nor anyone online had mentioned! The recommendation to track cost basis meticulously saved me from a potential headache years down the road. Definitely worth checking out if you're managing UTMAs.

After spending HOURS on hold trying to get clear guidance from the IRS about UTMA gain harvesting (they kept transferring me between departments), I finally found Claimyr (https://claimyr.com). They got me connected to an actual IRS agent in about 20 minutes - you can see how it works here: https://youtu.be/_kiP6q8DX5c The agent confirmed everything about the $1,250 tax-free threshold and explained some nuances about how dividends and interest in the UTMA count toward that limit too. They also clarified that I needed to file a separate tax return for my child once the unearned income exceeds a certain threshold, even with the gain harvesting strategy. Honestly, getting official confirmation straight from the IRS gave me the confidence to move forward with the strategy. No more guessing based on internet forums!

•Wait, how does this actually work? Do they just call the IRS for you or something? I've been trying to get through to ask about UTMA reporting requirements for weeks.

•This sounds like BS honestly. The IRS won't even answer their own phones - how could some random service get you through to them? And even if you do get through, most IRS phone agents give different answers to the same question.

•They use a callback service that basically waits on hold for you and then calls you when an actual agent picks up. So yeah, they do call the IRS for you, but the genius part is you don't waste hours of your life listening to that awful hold music. No, it's definitely not BS. I was super skeptical too, but it honestly works. The difference is Claimyr has systems set up to navigate the IRS phone tree efficiently and they know the best times to call. I tried for three days straight and couldn't get through, then Claimyr connected me in under 20 minutes. And the agent I spoke with was from the specialized investment income department, so they actually knew the UTMA rules specifically.

I have to admit I was completely wrong about Claimyr. After posting that skeptical comment, I decided to try it myself since I'd been struggling to get answers about my kids' UTMA accounts and whether I was correctly tracking their basis for tax reporting. The service connected me to an IRS tax law specialist in about 25 minutes (would have been hours if I tried myself). The agent confirmed that yes, harvesting gains up to $1,250 annually is a legitimate strategy, but also warned me about something important: if the UTMAs are generating dividends or interest, those count toward the same $1,250 threshold. So you need to subtract any dividends/interest from the $1,250 to know how much gain you can harvest tax-free. This clarification alone saved me from potentially over-harvesting gains and creating an unexpected tax bill. Worth every penny.

Don't forget about state taxes! The federal threshold is $1,250 for tax-free unearned income, but some states don't follow the same rules. I live in Tennessee and discovered that while we don't have state income tax on wages, we do tax certain investment income differently than the federal government does. Always check your specific state rules before implementing this strategy. In some high-tax states, you might still owe state tax even when you're under the federal threshold.

•Do you know if California follows the federal rules for this? I've tried researching but can't find a clear answer about UTMA accounts specifically.

•California unfortunately doesn't follow the federal thresholds for children's unearned income. California has its own set of rules and thresholds that are generally less favorable. Last I checked (and please verify this for 2025), California requires filing a state return if a child's income exceeds just $400, regardless of whether it's earned or unearned. So while you might stay under the federal threshold of $1,250 for tax-free gains, you could still end up owing California state tax on those gains. This is why it's crucial to consider both federal and state implications when implementing a gain harvesting strategy.

One question nobody's addressed - what happens if the market drops right after you sell and rebuy? I'm interested in this strategy but worried about timing the transactions.

•That's actually not a tax issue but a market timing risk. If you sell and the market drops before you rebuy, you'll actually benefit by being able to buy more shares at the lower price. The bigger risk is the opposite - selling and having the market jump before you can rebuy, missing out on gains. That's why most people execute the sell and buy orders very close together or even as simultaneous transactions if your brokerage allows it.

Great question about tax-loss harvesting for UTMAs! One important consideration that hasn't been mentioned yet is the impact on financial aid eligibility. UTMA assets are counted as student assets on the FAFSA at a much higher rate (20%) compared to parent assets (5.64%). While harvesting gains to step up basis is tax-smart, you might also want to consider the timing of when to do this relative to college planning. If your kids are getting close to college age, you may want to weigh the tax benefits against the potential impact on financial aid calculations. Also, make sure you're keeping detailed records of all these transactions. When your children eventually take control of the accounts, having clear documentation of cost basis adjustments will be crucial for their future tax planning.

This is excellent advice about the FAFSA implications! I hadn't considered how the 20% assessment rate on student assets could impact financial aid eligibility. This creates an interesting trade-off between tax optimization and college funding strategy. For families with younger children, the gain harvesting strategy makes perfect sense since you have years to benefit from the stepped-up basis. But as you get closer to college years, it might be worth running the numbers to see if the tax savings outweigh the potential reduction in financial aid. Another timing consideration: if you're planning to gift additional funds to the UTMA accounts, it might make sense to harvest gains first to free up "room" under the $1,250 threshold before adding new money that could generate additional dividends or interest. The record-keeping point is crucial too. I'd recommend creating a simple spreadsheet tracking each sale/repurchase transaction, the gain realized, and the new cost basis. Your kids will thank you for this documentation when they're older!

•This is really helpful context about the FAFSA implications that I hadn't considered! As someone new to UTMA planning, I'm wondering - is there a specific age cutoff where you'd recommend stopping the gain harvesting strategy to avoid hurting financial aid eligibility? Or does it depend more on the total account balance? Also, for the record-keeping spreadsheet you mentioned, should I be tracking anything beyond the basic sale/repurchase info? Like would it be useful to note the specific reasoning for each transaction or just the financial details?
