Can I claim my newborn as a dependent on my W4 for 2025 if baby is due mid-year?
I'm starting a new job next month and filling out all the paperwork. I'm currently expecting my first baby, due in June 2025. I'm confused about how to fill out the W4 form. Since my baby will be born this calendar year, can I go ahead and claim him/her as a dependent now on my W4? Or do dependents get prorated somehow since the baby will only exist for about half the year? I know this might be a silly question, but I have no experience with this stuff and want to make sure I'm doing it right from the start. Thanks for any help!

Congrats on your new job and upcoming baby! This is actually a great question. You CAN claim your baby as a dependent on your W4 for the entire year of 2025, even though they'll be born in June. The IRS doesn't prorate dependents - if your child is born at any point during 2025 (even December 31st!), they count as your dependent for the whole tax year. The W4 is just telling your employer how much to withhold from your paychecks. By claiming your baby now, you're reducing your withholding to account for the child tax credit and dependent exemption you'll be eligible for when you file your 2025 taxes next year.

•Thank you so much! That makes a lot of sense. So just to be absolutely clear - I won't be doing anything wrong by claiming the dependent now, even though the baby won't be here for a few more months? And I don't need to update my W4 again after the baby is born?

•You're absolutely welcome! You're doing nothing wrong by claiming your baby now on your W4. The form is simply setting your withholding for the year based on the tax situation you expect to have when you file your 2025 return next year. You won't need to update your W4 again after the baby arrives unless something else changes with your tax situation (like a significant change in income, marriage status, or additional dependents). Your W4 is just a planning tool - what really matters is your actual filing status and dependents when you submit your tax return next year.

I was in this exact situation last year and got so confused trying to figure it out! I ended up discovering taxr.ai (https://taxr.ai) which has this cool calculator that helped me figure out the exact withholding I should claim. You just upload your past tax docs or enter your info and it shows you how adding a dependent affects everything. I adjusted my W4 before my daughter was born in August and ended up with almost the perfect withholding amount.

•Did you actually have to show proof of pregnancy or anything? I'm due in October and wondering if my employer will question me claiming a dependent that doesn't exist yet.

•How accurate was it for calculating the child tax credit? I've heard mixed things about how that works for babies born during the tax year.

•No proof of pregnancy needed at all! Your employer doesn't verify your W4 information with the IRS - they just use it to calculate withholding. They don't need (or want) evidence of your family situation. The calculator was spot-on for the child tax credit. It showed me exactly how much I'd qualify for based on my income level and explained that babies born anytime during the tax year qualify for the full credit, not a prorated amount. It even helped me understand how the child tax credit phases out at higher income levels, which was super helpful.

Just wanted to follow up - I tried taxr.ai after seeing this thread and it was super helpful! I wasn't just confused about the W4 but also about how the child tax credit would work with our income. The site analyzed our previous returns and showed exactly how adding our baby would impact our taxes. It even caught that we should adjust our state withholding too, which I completely forgot about. Definitely gave me peace of mind that I'm not messing anything up!

If you're still waiting for a definitive answer from the IRS about this, good luck with their phone lines! I wasted HOURS trying to get through to ask a similar question. Finally used https://claimyr.com (they have a demo video here: https://youtu.be/_kiP6q8DX5c) and got connected to an actual IRS person in about 20 minutes instead of waiting for 3+ hours on hold. They confirmed that you can absolutely claim a child on your W4 if they'll be born anytime during the calendar year. Huge relief to hear it directly from them.

•How does this Claimyr thing actually work? Do they just call the IRS for you? Seems sketchy that they can somehow get through when regular people can't.

•Yeah right. No way they got you through to the IRS that fast. I've been trying to reach someone for weeks about my refund. Either you got extremely lucky or this is some kind of scam.

•They use an automated system that constantly redials until it gets through the IRS queue, then it calls you when it connects. You're still talking directly to the IRS yourself - Claimyr just handles the hold time for you. It's basically like having someone else sit on hold instead of you having to keep your phone tied up for hours. Definitely not a scam or luck - it's just automation doing what humans don't have the patience for. The video on their site shows exactly how it works. I was skeptical too until I tried it and suddenly had an IRS agent on the phone asking how they could help me.

I need to apologize to Profile 10 - I actually tried Claimyr yesterday after posting that skeptical comment. Got connected to an IRS agent in about 15 minutes! I asked about my refund delay AND about claiming a baby due later in the year on a W4. They confirmed everything people here already said - you can claim the dependent for the full year regardless of birth date. The agent even mentioned that this is one of their most common questions. Saved me hours of frustration and got a clear answer directly from the source.

Just to add another perspective - I'm an accountant and I always tell my clients to adjust their W4 as soon as they know they're expecting. There's no benefit to waiting until the baby arrives. The only thing to be careful about is if your income is close to the phase-out limits for the child tax credit (starts around $200,000 for single filers or $400,000 for married filing jointly). If you're near those thresholds, you might want to be more conservative with your withholding adjustments.

•What about state taxes? Do all states follow the same rules about babies born during the tax year?

•Great question about state taxes. Most states follow the federal rules regarding dependents, but there are always exceptions. States like California, New York, and Massachusetts generally allow you to claim a child born during the tax year as a dependent for the entire year. However, some states have different rules about their specific child tax credits or deductions. For example, certain states might have lower income thresholds for credit phase-outs than the federal government. If you're concerned, it's worth checking your specific state's tax department website or consulting with a tax professional familiar with your state's rules.

Your baby is considered your dependent for the entire tax year 2025 as long as they're born during 2025. I just went through this with my twins born in November last year. Someone told me I should update my W4 mid-year after they were born but that was wrong advice. You can (and should) claim them on your W4 now if you're starting a new job.

•Did you get the full child tax credit for both of your twins even though they were born in November? Seems like the government is being pretty generous!

As someone who just went through this exact situation last year, I can confirm what everyone else is saying - you absolutely can and should claim your baby on your W4 now! I was pregnant with my daughter due in September and was so worried about doing something wrong. I ended up calling my company's HR department and they told me the same thing - the IRS doesn't prorate dependents, so if your baby is born anytime in 2025, they count as your dependent for the whole year. What really helped me was keeping track of my paystubs after I updated my W4 to make sure the withholding looked reasonable. You'll see less tax taken out of each paycheck, which is exactly what should happen since you'll qualify for the child tax credit when you file your 2025 return. Don't stress about it - you're being smart by planning ahead!

•This is really reassuring to hear from someone who actually went through it! I'm definitely going to update my W4 when I start my new job next month. Quick question - did you notice a big difference in your take-home pay after claiming the dependent? I'm trying to budget for the baby and want to get an idea of how much extra I might have each month from the reduced withholding.

This thread has been super helpful! I'm in a similar situation - expecting my first baby in August 2025 and just accepted a new job offer. Reading through everyone's experiences has given me so much confidence about updating my W4. One thing I'm curious about - has anyone here dealt with having twins or multiples? I know each child counts as a separate dependent, so I assume you'd claim both on your W4 even if they're not born yet. Just want to make sure I understand this correctly since we just found out we're having twins at our last ultrasound! Also really appreciate the tip about keeping track of paystubs after updating the W4. That's definitely something I'll do to make sure everything looks right. Thanks everyone for sharing your real experiences with this - way more helpful than trying to decode IRS publications!

•Congratulations on the twins! Yes, you're absolutely right - each baby counts as a separate dependent, so you would claim both on your W4 even before they're born. Each child will qualify you for their own child tax credit (up to $2,000 per child for 2025), so claiming both now will reduce your withholding appropriately. Just be prepared for a more noticeable change in your take-home pay since you'll be accounting for two dependents instead of one! The withholding reduction will be more significant, but that's exactly what should happen since you'll be eligible for double the child tax credits when you file your 2025 return. It's so smart that you're planning ahead like this. Having twins is exciting enough without worrying about tax withholding on top of everything else!
