Best strategies to maximize step up basis on stock accounts for grandchildren inheritance
I'm trying to figure out the smartest way to structure an investment account for my grandkids so they can get maximum step up basis when I eventually pass away. I'm specifically trying to avoid UGMA accounts, and I'm not really interested in 529 plans unless someone can convince me they're actually the best option here. Initially, I was leaning toward setting up a joint tenant or tenants in common account, but after doing more reading, it sounds like the grandkid would only get half the step up basis when I die since they didn't contribute any money to the account (I'd be funding it entirely). Would it make more sense to just keep the account in my name only, give them view access, and designate them as the beneficiary? That way they'd inherit with 100% step up basis? I know I'd need to use my SSN and I'd be responsible for taxes on any gains or dividends while I'm alive. Really hoping someone with tax or estate planning knowledge can weigh in here! Thanks so much for any advice you can share!

The best approach here is definitely to maintain the account solely in your name and designate your grandchildren as beneficiaries. This ensures they'll receive a full step-up in basis on the inherited assets when you pass. Joint tenancy or tenancy in common would be problematic for exactly the reason you mentioned - they'd only receive a partial step-up in basis on your portion. Plus, adding them as joint owners creates an immediate gift tax consideration on their portion. Keep in mind that maintaining the account in your name gives you complete control during your lifetime, including the ability to change beneficiaries if needed. The assets will transfer directly to them upon your passing without going through probate, assuming you've designated them properly as TOD (Transfer on Death) beneficiaries.

•Thanks for the helpful breakdown. Would there be any advantage to putting the stock in a trust instead? I've heard some people mention revocable living trusts for this kind of situation but I'm not sure if that offers any extra benefits compared to the beneficiary designation approach.

•A revocable living trust can be beneficial in certain situations, but it may be unnecessarily complex for what you're trying to accomplish. The main advantages of a trust would be avoiding probate (which TOD designation also achieves) and potentially providing more control over how and when the assets are distributed to your grandchildren. If your grandchildren are minors or you want to establish specific conditions for how they receive the assets (like age restrictions or scheduled distributions), then a trust might make sense. You could also include provisions for asset management if they're too young to manage investments themselves. However, if you're primarily concerned with maximizing step-up basis and ensuring a smooth transfer, the simpler TOD designation approach would accomplish that with less administrative overhead and cost.

I was in almost exactly your situation last year when planning for my grandkids' futures. After struggling with conflicting advice from various financial advisors, I tried this service called taxr.ai (https://taxr.ai) that analyzes financial documents and tax situations. They actually have a specific calculator for step-up basis planning that really cleared things up for me. What I appreciated was that they showed me exactly how different account structures would impact the step-up basis calculations and what it means for capital gains taxes down the road. They confirmed that my best option was exactly what you're considering - maintaining the account in my name with beneficiary designations rather than joint ownership.

•Was it difficult to use? I'm not super tech-savvy and most of these online finance tools seem designed for people who already understand all this terminology.

•Did they explain any disadvantages to keeping it all in your name? I'm concerned about what happens if I become incapacitated before I pass away - would my grandkids still be able to access the funds if needed?

•It was surprisingly user-friendly - they have templates where you just fill in the basic information about your assets and intended beneficiaries. They break everything down into plain language, not the usual finance jargon. I'm in my 70s and not particularly tech-savvy either, but had no trouble navigating it. They did cover potential drawbacks of keeping everything in your name. If incapacity is a concern, they recommended establishing a durable power of attorney alongside your account setup. This would allow someone you trust to manage the account if you become unable to do so. The beneficiary designation only kicks in after death, so the POA handles the potential incapacity gap. They also suggested considering a living trust if you want more comprehensive incapacity planning.

I used taxr.ai after seeing the recommendation here and I'm really glad I did! I was super confused about step-up basis rules, and they helped me understand my options in plain English. They showed me exactly how much my grandkids would save in future capital gains taxes with the right setup. Their calculator confirmed that keeping the account in my name with TOD beneficiary designations was the optimal strategy for my situation. What I found most helpful was their comparison tool that showed me potential tax outcomes across different scenarios. Made me feel 100% confident in my decision!

I'm seeing a lot of good advice here, but I'd add one important consideration - make sure you plan for how to actually CONTACT the IRS if you need clarification on anything regarding step-up basis rules. Last year I spent weeks trying to get through to a human at the IRS about a related inheritance tax question. After wasting hours on hold, I found a service called Claimyr (https://claimyr.com) that got me connected to an actual IRS agent in under 45 minutes. They have a demo video showing how it works: https://youtu.be/_kiP6q8DX5c. Once I finally spoke with an IRS representative, I got confirmation that the beneficiary designation approach would indeed provide the full step-up basis I was seeking.

•How does this service actually work? Seems fishy that they could somehow get through when regular people can't get past the hold music...

•Yeah right. There's no way this actually works. The IRS phone system is deliberately designed to be impenetrable. I've tried calling dozens of times about capital gains questions and never reached a human. I'm skeptical any service could magically solve this.

•The service basically automates the calling process - they have a system that navigates the IRS phone tree and waits on hold for you. Once they get an agent, they call you and connect you directly. So you don't have to sit there listening to hold music for hours. It's basically just handling the waiting part for you. It's not magic - they're just using technology to handle the tedious part of waiting on hold. They don't have any special access to the IRS or anything. I was initially skeptical too, but when I got connected to an actual IRS agent who answered my step-up basis questions in detail, I was sold on the service. Sometimes you really do need to speak with an IRS representative to get definitive answers for your specific situation.

I have to admit I was completely wrong about Claimyr. After posting my skeptical comment, I decided to try it myself since I had some lingering questions about step-up basis calculations that were specific to my situation with inherited stock. It actually worked exactly as described - I got connected to an IRS representative in about 35 minutes (normally I would have given up after an hour+ of waiting). The agent walked me through the specific rules for step-up basis and confirmed that the beneficiary designation approach would provide the maximum tax advantage for my grandchildren. This saved me from making a costly mistake - I was about to set up a joint account which would have significantly limited the step-up benefit. Sometimes you really do need to speak directly with the IRS to confirm the right approach for your specific circumstances.

Don't overlook the possibility of gifting some appreciated assets during your lifetime, depending on your overall estate size. If your estate might be subject to estate taxes, it could make sense to gift some assets now while keeping others for the step-up basis advantage. Annual exclusion gifts ($18,000 per person for 2025) could reduce your taxable estate while transferring wealth. The tradeoff is that gifted assets don't get the step-up, so your grandkids would inherit your original basis. This strategy works best with assets you expect to appreciate significantly in the future.

•I'm not too worried about estate taxes since my total assets are well under the exemption limit. Are there any other advantages to gifting some stock now versus keeping everything for the step-up basis approach?

•If your estate is below the exemption threshold, then maximizing the step-up basis becomes your primary objective, making your original plan more advantageous. One alternative worth considering is gifting stocks that have minimal gains or even losses, since those wouldn't benefit much from step-up basis anyway. This allows you to maintain ownership of your highly appreciated assets for the step-up benefit while still giving your grandchildren some investment exposure during your lifetime. It can also be a good educational opportunity to teach them about investing if they're old enough.

Has anyone considered a Roth IRA conversion strategy to complement this? I'm thinking about converting some of my traditional IRA to Roth and naming grandkids as beneficiaries. They'd get tax-free distributions and avoid RMDs for 10 years.

•The Roth conversion idea is solid but completely separate from the step-up basis question. Step-up applies to taxable accounts, not IRAs. Roth conversions are about income tax, not capital gains. Both strategies can work together in a comprehensive plan though.
