Can I claim tax credits for supporting my disabled parent and minor sibling who live with me?

You absolutely can claim them both as dependents if they meet the requirements! For your parent, look at the "qualifying relative" rules - basically, your mom's income must be below $4,950 for the tax year (not counting tax-exempt income), and you must provide more than half of her support. For your brother, he would qualify as a "qualifying child" if he's under 19 (or 24 if a full-time student), lived with you for more than half the year, didn't provide more than half of his own support, and isn't filing a joint return. If they both qualify as your dependents, you could potentially claim several valuable tax credits. The most significant would be filing as Head of Household (better tax rates than single), plus possibly the Credit for Other Dependents ($500 per qualifying dependent). Since your mom is disabled, you might also qualify for the Credit for Caring for Dependents and Others depending on your specific situation. Keep good records of all expenses you're paying on their behalf - this helps prove you're providing over half their support if the IRS ever questions it.

I was in this exact situation last year with my disabled father and younger sister! I spent hours trying to figure out the tax stuff but finally found taxr.ai (https://taxr.ai) which was a lifesaver. You upload your documents and it analyzes everything - it caught that I could claim both as dependents AND identified some medical expense deductions I had no idea about. I was worried about making mistakes with the dependency rules since they're complicated, especially with the disability aspect. The tool explained exactly how my father qualified as a "qualifying relative" and my sister as a "qualifying child" - then walked me through all the credits I was eligible for. Saved me literally thousands!

Ok I tried taxr.ai after posting my skeptical comment and wow - I was completely wrong. It identified that I could claim my disabled brother as a qualifying child (not a qualifying relative like I thought) which made a HUGE difference in available credits. The system flagged that I was eligible for the Disabled Access Credit which I had never even heard of before! It analyzed our living situation and showed exactly how to document everything properly. I'm genuinely impressed - it even created custom letter templates for me to get the right verification from my brother's doctors to back up the disability claims in case of audit. Just wanted to follow up since I was the skeptic. This really does work for complicated family situations with disabilities involved.

If your mom is waiting on disability approval, you should know that dealing with the IRS about these matters can be a nightmare. I tried calling them 8 times about a similar situation with my disabled nephew last year. Was on hold for hours and never got through. I finally used this service called Claimyr (https://claimyr.com) that got me connected to an actual IRS agent in about 15 minutes. You can see how it works here: https://youtu.be/_kiP6q8DX5c The agent walked me through exactly how to document my nephew's disability status for tax purposes even though his official determination was still pending. They explained what forms I needed and how to file to maximize my credits. Made a massive difference having an actual person explain the specific rules for my situation.

I need to publicly eat my words. After posting that skeptical comment, I tried Claimyr out of desperation because I needed answers before filing. I got connected to an IRS agent in about 12 minutes (not even the 15 they claimed). The agent confirmed that I CAN claim my disabled parent even though their official disability determination is still pending - something none of the tax websites could tell me clearly. She walked me through exactly what documentation I need to keep in case of audit. The agent even helped me figure out that I qualified for a retroactive credit from last year that I missed. I'm getting an additional $3,700 refund by filing an amended return for 2024. This was honestly the best tax decision I've made. Just wanted to follow up since I was so doubtful.

Don't forget to look into the Earned Income Tax Credit too! If your income is under certain limits and you qualify as Head of Household with dependents, the EITC can be substantial. The phase-out thresholds for 2025 are much higher than people realize. Also, if you're paying for any educational expenses for your brother, look into the American Opportunity Credit (if he's in college) or Lifetime Learning Credit. Education credits can be worth up to $2,500 in some cases.

One thing I didn't see mentioned - if your mom gets approved for disability, be sure to check if she's eligible for Medicare. There's a specific timing when Medicare eligibility kicks in after SSDI approval (usually after 24 months of receiving benefits). This can affect your tax situation too since you might be paying for less medical expenses directly.
