Can I deduct 529 contributions after divorce with shared custody?
I finalized my divorce about 6 months ago and have joint custody of my daughter. During the marriage, my ex-wife and I had set up a 529 college savings account for our daughter, but after the divorce, she retained ownership of the account. According to our divorce agreement, we're both supposed to keep contributing to this 529 plan, and I've got monthly automatic deposits set up. I'm starting to wonder if this arrangement makes sense tax-wise. I want to claim the tax deduction for my contributions, but I'm not sure if I can since my ex is the official account owner. Is there any way we can separate our contributions so we can each deduct what we put in on our respective tax returns? Or should I just open a separate 529 with me as the owner? Having everything in one account would be simpler for tracking purposes, but not if it means I lose out on tax benefits. I'm not particularly knowledgeable about tax implications of 529 plans post-divorce, so any advice would be greatly appreciated!

529 plan tax benefits can get tricky after divorce! First, it's important to understand that 529 contributions aren't deductible on your federal taxes - they're only potentially deductible on state returns, and only in certain states. For state tax deductions, most states that offer deductions require you to be the account owner to claim the deduction. If your ex is the sole owner, you likely can't claim state tax deductions for your contributions under the current arrangement. You have two good options here: 1) Open your own 529 account with your child as beneficiary. This way, you'll each have your own account and can each potentially claim state tax deductions for your respective contributions. 2) See if your ex would be willing to add you as a joint owner on the existing account, though not all 529 plans allow this. From a practical standpoint, having separate accounts isn't necessarily a bad thing - it gives you both control over your own contributions and investments, and your child can use funds from both accounts for educational expenses.

•Would it make any difference if his state doesn't offer 529 deductions? And what about the gift tax implications? I thought there was a limit you could contribute tax-free.

•If your state doesn't offer 529 deductions, then there's no tax advantage to being the account owner from a deduction perspective. In that case, continuing with the current arrangement wouldn't cause you to lose any tax benefits, and keeping everything in one account might be simpler. Regarding gift tax implications, 529 contributions are considered gifts for tax purposes. In 2025, you can give up to $19,000 per recipient without filing a gift tax return. There's also a special rule for 529 plans that allows you to front-load five years of gifts at once (up to $95,000) with a special election on your tax return. These gift tax rules apply regardless of whether you're the account owner or not - they're based on who contributes the money.

After my divorce, I was confused about the same 529 issues until I found taxr.ai (https://taxr.ai). Their system analyzed my divorce decree and tax situation, then gave me personalized guidance about claiming education savings contributions. It showed me that in my state (Illinois), I needed to be the account owner to get the state tax deduction, so I ended up opening my own account. What I liked is that they showed me exactly which parts of my divorce agreement affected my tax situation and guided me through what forms I needed. They also helped me understand how the account ownership impacts financial aid calculations when my kid applies for college. Definitely worth checking out for post-divorce tax questions like this!

•How does it work? Do I just upload my divorce paperwork and it figures everything out? Seems too easy tbh.

•Does it cover all states? I'm in Pennsylvania and nobody seems to know how our state handles 529s after divorce.

•You upload your documents and it uses AI to analyze them based on your specific situation. It walks you through any additional information needed and then gives you a complete breakdown of your tax situation. It's designed to be simple but it's actually doing complex analysis behind the scenes. Yes, it covers all states! I've heard from friends in Pennsylvania who used it. The system knows the specific 529 rules for Pennsylvania and how they interact with divorce situations. It also explains which parts of your divorce decree affect different tax situations, not just for 529s but for dependent claims, property transfers, and other divorce-specific tax issues.

Just wanted to update everyone - I tried taxr.ai after seeing it mentioned here. It was super helpful for my situation with 529 plans after divorce. I uploaded my divorce agreement and tax info, and it immediately pointed out that I needed to be the account owner to claim the PA state tax deduction. I also learned that our divorce agreement had some wording that could have caused issues with the IRS down the road. The tool explained exactly what sections were problematic and why. I'm meeting with my ex next week to discuss setting up separate accounts based on the recommendations. Saved me from making an expensive mistake!

When I was trying to figure out similar 529/divorce tax issues, I spent WEEKS trying to reach someone at the IRS who actually understood this specific situation. Kept getting transferred around and put on hold forever. Finally someone told me about Claimyr (https://claimyr.com) - checked out their demo video at https://youtu.be/_kiP6q8DX5c and decided to try it. Got connected to a real IRS agent in about 15 minutes who actually specialized in education benefits after divorce! They confirmed that in my case, I needed to be the account owner to claim state tax benefits. The agent also explained some important nuances about how the funds would be treated for financial aid purposes that I hadn't even considered. Definitely recommend if you need specific answers from the IRS about complex situations like 529s after divorce. Saved me hours of frustration!

•How does this actually work? Do they just call the IRS for you? Couldn't I just do that myself?

•Sounds fishy to me. The IRS doesn't have "specialists" in education benefits after divorce. They just interpret the tax code. I'll stick with my CPA thanks.

•They use some sort of callback technology that navigates the IRS phone system for you. When an agent is actually on the line, it rings your phone and connects you directly. You don't have to sit through all the holds and transfers yourself. It's basically like having someone wait on hold for you. I understand your skepticism - I felt the same way! What I meant was that I got connected to someone in the education tax credits department who happened to have experience with divorce situations. You're right that there's not a specific "divorce 529 specialist" title at the IRS. But there are definitely agents who have more experience with certain types of tax questions than others. The advantage was getting to an agent who understood my situation without spending hours on hold or getting transferred multiple times.

I'm eating my words right now. After being skeptical about Claimyr (in my reply above), I decided to try it anyway because I was getting nowhere with the IRS about my own 529/divorce situation. Got connected to an agent in just under 20 minutes who confirmed that in my state (Maryland), I absolutely needed to be the account owner to claim the state tax deduction. The agent also explained a special rule I didn't know about - since our divorce was finalized mid-year, there were specific guidelines about how to handle the contributions made before versus after the divorce. Never been happier to be wrong. Saved me from making a pretty costly mistake on my taxes!

I went through this exact situation last year. Here's what my tax advisor told me: if state tax deductions matter to you, open your own 529. In most states that offer deductions, you need to be the account owner. But keep in mind that having two accounts means two sets of maintenance fees and potentially different investment options. One creative solution we found: we kept my ex's existing 529 but adjusted our divorce agreement to state that my "contribution" would actually be paying additional child support, and my ex would increase her 529 contributions by the same amount. This way she gets the tax deduction (which was fair since she's in a higher tax bracket anyway), and we avoided the hassle of multiple accounts.

•That's actually a really interesting solution I hadn't considered. Did you have to formally amend your divorce agreement to make this change? And did your ex agree pretty easily to this arrangement?

•Yes, we did formally amend the agreement through our attorneys. It wasn't too complicated since we were making other minor adjustments anyway. My ex was actually pretty receptive to the idea because it simplified things for both of us. Since she was in a higher tax bracket, the deduction was worth more to her, so it made financial sense. We calculated the exact benefit she'd get from the deduction and adjusted the child support numbers to make it fair. The key was approaching it as a win-win rather than a competition. Our mediator was really helpful in presenting it that way.

Don't forget about the financial aid implications! When your kid applies for college, 529 plans owned by parents are counted as parental assets (assessed at a max of 5.64% for financial aid), but 529s owned by grandparents or other relatives used to not count at all until the money was withdrawn. This changed recently though - starting with the 2024-2025 FAFSA, distributions from grandparent-owned 529s no longer count as student income. So the old strategy of having grandparents own the account doesn't have the same advantage it used to. But there's still a consideration with divorce - the custodial parent's finances are what matter for FAFSA. If your ex is the custodial parent and also owns the 529, it could affect financial aid differently than if you (the non-custodial parent) own a separate 529.

•This is incorrect. The new FAFSA does ask about money received from grandparents now. They changed it again!

I went through a similar situation with my divorce two years ago. Here's what I learned: the key is understanding your state's specific rules about 529 deductions. In my case (Ohio), I had to be the account owner to claim the state tax deduction, so I ended up opening my own 529 account. One thing to consider that hasn't been mentioned yet - check if your state has a "recapture" provision. Some states will require you to pay back previous tax benefits if you change the beneficiary or if the account owner changes. This didn't affect me since I opened a new account, but it's something to be aware of if you're thinking about transferring ownership of the existing account. Also, don't overlook the investment management aspect. When you have separate accounts, you each get to choose your own investment strategy, which can actually be beneficial. My ex is more conservative with investments while I'm more aggressive, so having separate accounts lets us each manage according to our risk tolerance while still working toward the same goal of funding our daughter's education. The paperwork is a bit more complex come tax time, but it's worth it for the flexibility and potential tax benefits.

•Thanks for bringing up the recapture provision - that's something I hadn't heard about before! Do you know which states typically have these rules? I'm in California and wondering if this could affect me if I decide to open my own account versus trying to get added to the existing one my ex owns. Also, when you say the paperwork is more complex at tax time, are you just talking about tracking contributions from multiple accounts, or are there other forms involved?

•California doesn't have recapture provisions for 529 plans, but that's mainly because California doesn't offer state tax deductions for 529 contributions in the first place! So you wouldn't lose any tax benefits by opening your own account versus being added to your ex's account. Regarding the paperwork complexity, it's mostly about tracking contributions from multiple accounts. You'll need to keep records of how much you contributed to each account for your own records, and if you're in a state that offers deductions, you'll need to report those accurately. There aren't really additional tax forms - the complexity is more about organization and record-keeping to make sure you're not double-counting anything or missing deductions you're entitled to. Since you're in California, the main considerations for you would be control over investment choices and simplicity of tracking rather than tax benefits.
