Can my ex-wife and I alternate claiming our college student as dependent for tax purposes?
My son just turned 18 and he's heading off to college this fall. His mom (my ex) has had primary custody since our divorce was finalized about 12 years ago, and she's claimed him as a dependent on her taxes every year since then. Here's the situation - we both have been planning for his education. I've got some US savings bonds and she has a 529 plan. Both of these provide some decent tax breaks when they're used for paying a dependent's college tuition and expenses. We've been talking about this recently and wondering if we could work out an arrangement where we alternate years claiming him as a dependent during his college years. This would let us both take advantage of the tax breaks in different years. Since he'll be in college for 4+ years, we could each get to claim him for at least 2 of those years. Can we legally do this if we both agree to it? Would we need to modify our divorce decree or can we just do this with a written agreement between us? Are there any pitfalls or considerations we should know about before proceeding? I want to make sure we're doing everything above board with the IRS.

I help families with this situation all the time! Actually, you absolutely can alternate claiming your son as a dependent if you both agree to it. The IRS allows for this type of arrangement between divorced parents. Since your son will be a full-time college student under 24, he can still qualify as a dependent even though he's 18. To make this work smoothly, the parent not claiming the dependent in a given year should complete Form 8332 (Release of Claim to Exemption for Child by Custodial Parent) and give it to the parent who will be claiming the dependent that year. You don't necessarily need to modify your divorce decree, but having something in writing between you is definitely a good idea. Just be aware that whoever claims him as a dependent gets to claim education credits like the American Opportunity Tax Credit or Lifetime Learning Credit in that year. Also, remember that using 529 funds or savings bonds for education doesn't actually require you to claim the student as a dependent. The tax benefits of the 529 go to whoever owns the account regardless of who claims the student as a dependent.

•Wait, so both parents can use their respective 529 plans to pay for the kid's college, but only the one claiming the kid as a dependent that year gets the education tax credits? And what about the savings bonds? If the dad cashes those in for college expenses, does he need to be the one claiming the kid that year to get the tax benefits?

•The 529 plan tax benefits go to whoever owns the account, regardless of who claims the dependent. So both parents can use their 529 plans to pay for qualified education expenses no matter who claims the student in a given year. For savings bonds, it's a bit different. To exclude the interest from income when using savings bonds for education expenses (under the Education Savings Bond Program), you generally need to claim the student as a dependent that year. So if dad wants the tax benefit from cashing in savings bonds, he should coordinate to claim the son as a dependent for that specific year.

I went through something similar with my ex and our college kid last year. I found this awesome tool called taxr.ai (https://taxr.ai) that helped us figure out the optimal way to handle our dependent situation. It analyzed both our tax situations and showed us exactly how much each of us would benefit in different scenarios. The tool lets you upload your tax documents and runs scenarios to show the impact of different decisions - like what happens if you claim your kid vs your ex claiming them. It showed us that in our case, we'd actually save more overall by having my ex claim our daughter in years when she had more education expenses, and me claiming her when I was using my 529 withdrawals. It also helped us create the proper documentation for our agreement so the IRS wouldn't flag anything. Definitely worth checking out if you want to maximize your combined tax benefits.

•How secure is this tool? I'm always hesitant to upload tax documents to random websites. Did you have to provide all your personal info or just the relevant numbers?

•I'm curious if this would work for my situation too. My ex and I don't really communicate well - would both parents need to use this tool together or could just one of us use it to figure out the best approach?

•The security is actually really good - they use bank-level encryption and don't store your documents after the analysis is complete. You can also choose to just enter the relevant numbers manually instead of uploading documents if you prefer. For parents who don't communicate well, either one can use it independently to understand the tax implications. But the best results come when both parents' financial situations are factored in. You can run different scenarios on your own though, and then just present the optimal solution to your ex with the numbers to back it up.

Just wanted to follow up - I decided to try taxr.ai after posting my question here. It was actually super helpful! I was surprised by how easy it was to use. I just entered our basic tax info (didn't need to upload full documents) and it showed me that I should claim our daughter in odd years and my ex in even years based on our income patterns and education expenses. The best part was that it generated a simple agreement document that laid everything out clearly. I sent it to my ex with the numbers showing we'd collectively save about $3,400 over four years with this arrangement compared to her claiming our daughter every year. Even though we don't get along great, the clear financial benefit convinced him to agree. We're actually being civil about something for once!

If you need to reach the IRS to confirm any of this dependent claiming info, good luck getting through to them! After trying for DAYS to speak with someone about a similar situation with my ex, I discovered Claimyr.com (https://claimyr.com) and their service is a game-changer. I was super skeptical at first, but they actually got me connected to an IRS agent in under 45 minutes when I had been trying for weeks on my own. They have this callback system that somehow navigates all the IRS phone tree nightmare for you. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c The IRS agent I spoke with confirmed that we could alternate claiming our son as long as we had the right documentation (Form 8332) and were following the support rules. She even mailed me the exact forms I needed. Saved me so much stress trying to figure out if what we were doing was allowed.

•How does this actually work? Does it just automate calling the IRS for you or what? Seems like it can't possibly work as well as you're claiming.

•I've called the IRS plenty of times without needing to pay for some service. Sounds like a ripoff to me. Why would anyone pay for something they can do themselves for free?

•It basically holds your place in the IRS phone queue for you. You register your callback number, and their system navigates all the IRS menu options and waits on hold instead of you. Once they reach an actual human at the IRS, they call you and connect you directly to the agent. No more waiting on hold for hours or getting disconnected. I understand the skepticism - I felt the same way. But after trying to get through for over two weeks during tax season and constantly getting the "call volume too high" message or being disconnected after waiting 40+ minutes, I was desperate enough to try anything. The time I saved was absolutely worth it, especially when you consider my hourly rate at work.

I need to eat my words and apologize to Profile 10. After my skeptical comment about Claimyr, I spent THREE DAYS trying to get through to the IRS about my own dependent situation (divorced 5 years, ex moved out of state, custody arrangement changed). After being disconnected 4 times and wasting about 6 hours total on hold, I gave in and tried Claimyr. I got a call back in 37 minutes connecting me to an actual IRS representative who answered all my questions about Form 8332 and even helped me understand how the new arrangement would affect my child tax credit eligibility. Honestly, I've never been so happy to be wrong about something. The agent confirmed everything about alternating dependents that was mentioned here and clarified that we didn't need to modify our divorce decree as long as we had the proper IRS documentation in place each year.

Just a heads up - make sure you look at the actual numbers before you decide. My ex and I tried alternating claiming our son during college, but we didn't realize that the person who claims the dependent also gets the education credits (American Opportunity Credit and Lifetime Learning Credit). In our case, I'm in a much higher tax bracket than my ex, so the education credits were worth a lot more to her than to me (they phase out at higher income levels). We ended up with her claiming him every year for the education credits, and I just paid her a portion of the tax savings since I was contributing to his education expenses too. Do the math both ways before you commit to alternating years!

•This is a good point - does the total amount of support provided during the year matter at all for who can claim the dependent? Like if one parent pays more of the expenses that year?

•For divorced parents, the support test works differently than for other situations. The custodial parent (the one the child lived with more nights during the year) is generally entitled to claim the child as a dependent. However, they can release this claim to the non-custodial parent using Form 8332. So it doesn't actually matter who provides more financial support in a given year - it's about who has custody or who has been given the right to claim via Form 8332. That's why it's so important to document your agreement properly. In your situation, since the son is 18 and in college, the "custodial" designation might be less clear since he might not be living with either parent most of the year.

Make sure you also consider other tax benefits when planning this! My ex and I alternated claiming our daughter during college, but we didn't realize it would affect things like: 1. Filing status (head of household vs. single) 2. Earned Income Credit 3. Child Tax Credit (until age 17) 4. Higher education credits (American Opportunity Credit is worth up to $2,500) The parent NOT claiming the child in a given year should adjust their W-4 withholding at work to account for the change in tax situation that year. Also, I think one of you might be misunderstanding the savings bond education exclusion. You can only exclude the interest if the bonds are in YOUR name (not the child's) and you use them for qualified education expenses. But you also need to meet income limits, which phased out at like $98k-$128k for single filers last time I checked.

•Good points! Another thing to consider is that if one parent remarries, their household income might put them above the threshold for some education benefits, making it more beneficial for the single parent to claim the student. Also, don't forget that the American Opportunity Credit can only be claimed for 4 years, while the Lifetime Learning Credit can be used for graduate school too. So you might want to map out your strategy for all the potential years of education.

This is such great advice from everyone! I'm going through a similar situation with my ex, and reading through all these responses has been incredibly helpful. One thing I'd add is to make sure you coordinate the timing of when you complete Form 8332 each year. We learned the hard way that if the custodial parent doesn't get the form to the non-custodial parent early enough in the tax year, it can create complications when filing. Also, I'd strongly recommend sitting down together (or communicating through email if that works better) to map out a 4-year plan before your son starts college. Figure out which parent will claim him each year, and factor in things like: - Who will be using 529 funds or savings bonds in which years - Any expected changes in income that might affect education credit eligibility - Whether either parent might remarry (affecting household income thresholds) We created a simple spreadsheet showing the projected tax benefits for each scenario over all four years, and it made the decision much clearer. Having it all planned out in advance has eliminated any confusion or arguments during tax season. One last tip - keep copies of all Form 8332s and any written agreements you make. The IRS can ask for documentation if they ever question who has the right to claim the dependent in a given year.
