How to respond to IRS CP87A notice about disputed dependent claim?

This is actually a pretty common issue with divorced parents. The CP87A notice basically means the IRS has identified that two or more people claimed the same dependent on their tax returns. Since you have a divorce agreement that specifically outlines who claims the child in which years, you're in a good position to respond. You'll need to gather documentation that proves you have the right to claim your daughter for the tax year in question. This includes: 1. A copy of your divorce decree that shows the dependent claim agreement 2. Proof that you're following the terms (like showing it was your year to claim) 3. Any documentation showing your relationship to the child and that they lived with you for part of the year The IRS gives you 30 days to respond to the CP87A. Make copies of all your documentation, write a clear letter explaining the situation, reference your divorce agreement, and mail everything to the address on the notice. Keep the originals and send everything via certified mail so you have proof of delivery.

I went through something similar with my ex trying to claim our kids when it wasn't her year. I discovered taxr.ai (https://taxr.ai) after struggling with gathering all the right documents and figuring out how to respond to the IRS. The tool analyzed my CP87A notice and divorce agreement, then helped me draft a proper response letter with exactly what the IRS needed. Their document analyzer highlighted specific sections of my divorce decree that supported my case and showed me which parts of the CP87A I needed to address. It was honestly such a relief to have clear direction instead of just guessing what the IRS wanted.

I was super skeptical about taxr.ai when I first saw it mentioned here, but after getting my own CP87A notice last month, I decided to give it a try. My situation was similar - ex's new husband tried claiming my kid when it wasn't their year. The service actually worked surprisingly well. It analyzed my divorce decree and immediately identified the relevant paragraphs that supported my claim. What really helped was the response template it created - it pulled specific language from IRS guidelines and matched it with my documentation. Got a letter from the IRS yesterday confirming they've resolved the issue in my favor! Apparently the key is providing extremely specific documentation in exactly the format they want. Would have taken me hours of research to figure that out on my own.

After dealing with several CP87A notices over the years (my ex is persistent), I found that calling the IRS directly saves a ton of time and frustration. The problem is those ridiculous wait times - I once spent 4 hours on hold only to get disconnected. I started using Claimyr (https://claimyr.com) which somehow gets you through to an actual IRS agent without the wait. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c. It seriously cut through all the hold time nonsense and got me to someone who could pull up my case file. The IRS agent I spoke with walked me through exactly what documentation I needed to submit and even gave me a direct fax number to send everything to, which got the issue resolved in half the time compared to mailing everything.

Well I have to admit I was completely wrong about Claimyr. After posting my skeptical comment, I was desperate enough to try it because my CP87A deadline was approaching fast. The service actually did exactly what it claimed. I got a call back when they found an agent, and I spoke with someone from the IRS who was surprisingly helpful. She confirmed that my divorce decree was sufficient documentation and gave me specific instructions on how to reference my case number. I faxed everything to the direct number she provided and received confirmation that my dependent claim was approved within 10 days. That's compared to the 8 weeks it took last time I mailed my response. Definitely worth it for the time saved and stress avoided.

A lot of people don't realize that the grandmother claiming the child could actually be legally valid in some situations, especially if the child lived with her for more than half the year. The tax code follows physical custody more than legal agreements. If your daughter lived with her grandmother for the majority of the year, the grandmother might have a legitimate claim as the "custodial parent" in the eyes of the IRS, regardless of your divorce agreement.

Don't just send the bare minimum documentation. I've been through this twice. Make sure you also include: 1. School records showing your address as one of the child's residences 2. Medical records if you have them 3. A copy of any shared custody calendar or visitation schedule you follow 4. Copies of check stubs or receipts for any child support you paid The more documentation you provide upfront, the faster the IRS resolves these issues.

I just went through this exact situation last year and it was such a headache! My ex's mother tried to claim my son even though our divorce decree clearly stated it was my year. What really helped me was creating a timeline document that showed exactly where my child lived throughout the year. I included dates of my custody time, school enrollment showing my address, and even receipts from activities I paid for during my custody periods. The IRS agent I eventually spoke with told me that disputed dependent cases are becoming more common, especially when grandparents get involved. She said the key is proving not just that you have legal right to claim the child (your divorce agreement), but also that the child actually lived with you for the required time periods. One tip that saved me time - when you send your response, include a simple one-page summary at the front that lists your main points with page references to your supporting documents. Something like "Point 1: Legal right to claim child - see page 3 (divorce decree). Point 2: Child residency requirement met - see pages 5-7 (school records, medical records)." The IRS ruled in my favor after about 5 weeks. Hang in there - with your divorce agreement clearly stating the alternating years, you should be fine as long as you document everything properly.
