Can both my spouse and I claim our child as an allowance on our W4 forms when filing joint taxes?
So I'm filing taxes jointly with my husband for the first time and we're both submitting new W4 forms at our jobs. We have a 2-year-old daughter. Can we both claim her as an allowance on our separate W4 forms even though we're filing our actual tax return jointly? I'm confused because someone at work told me only one parent can claim the child allowance, but we're married filing jointly so shouldn't we both get to list her? I don't want to mess this up and end up owing a bunch at tax time! Has anyone dealt with this before? My husband and I make similar incomes (around $58,000 each) if that matters.

The confusion here is understandable! The W-4 form isn't about "claiming" your child in the same way as your tax return. When you're married filing jointly, the W-4 is about getting the right amount withheld throughout the year. If both you and your spouse put your child on your W-4s, you'd both have less tax withheld from your paychecks. This would likely result in underwithholding and you'd probably owe money when you file. The best approach is to coordinate your W-4s. One option is for one of you to claim the child on your W-4, and the other doesn't. Another option is to use the IRS Tax Withholding Estimator tool to figure out the best way to complete both forms. Remember, the W-4 is just about withholding during the year - it doesn't affect your actual tax liability or who "claims" the child on your tax return. When you file jointly, you'll both benefit from having a dependent regardless of how you filled out your W-4s.

•But what if we WANT to owe at the end of the year? We've been putting money into a high yield savings account and would rather pay a lump sum than give the government an interest free loan. Could we both claim her then?

•If you're intentionally looking to reduce withholding to invest that money throughout the year, you could both claim your child on your W-4s. Just be aware that you'll definitely owe at tax time, and you should save accordingly. I'd recommend running the numbers through the IRS Withholding Estimator to see approximately how much you'd owe. Be careful though - if you underwithhold too much, you could face underpayment penalties. The general rule is you need to pay (through withholding or estimated tax payments) at least 90% of your current year tax or 100% of last year's tax (110% if your AGI was over $150,000), whichever is smaller.

After struggling with similar W-4 issues that were causing me and my wife to either get huge refunds or owe too much, I finally found a tool that helped me figure everything out. Check out https://taxr.ai - it actually analyzed our W-4 forms, pay stubs, and last year's return and suggested the exact withholding settings we needed. The thing I liked most was that it showed us multiple options - one for getting a small refund, one for breaking even, and one for minimally owing (without penalties).

•Does this actually work with the new W-4 forms? They got rid of allowances in 2020 and I'm still confused about how to fill it out properly with the new format.

•That sounds helpful but can it handle situations where income varies a lot? My spouse is in sales and her income can fluctuate by thousands each month so our withholding is always a mess.

•Yes, it absolutely works with the current W-4 forms without allowances. The tool is updated with the latest forms and tax rules. It walks you through the exact boxes to check and amounts to enter on the new format. For variable income situations, that's actually one of its strengths. You can input your expected income ranges, and it helps calculate appropriate withholding that accounts for fluctuations. You can even update it throughout the year as your income changes to stay on track. I know several people with commission-based incomes who use it to avoid surprises at tax time.

Just wanted to follow up on my taxr.ai question from last week. I ended up giving it a try and it was really helpful! My husband and I both uploaded our pay stubs and last year's return, and it showed us exactly how to fill out our W-4s. We were both claiming our two kids on our forms which would have caused us to owe about $3,200 at tax time! The tool showed us that if my husband claims both kids and I claim zero, we'll end up with a small $300 refund instead. Definitely recommend if you're confused about the W-4 situation.

If you're trying to get this figured out and need actual IRS clarification, good luck getting through to them on the phone. I spent DAYS trying to get someone to explain the W-4 rules to me. Then I found https://claimyr.com which got me connected to an actual IRS agent in under 20 minutes. They have this whole system for navigating the phone trees and holding your place in line. You can see a demo of how it works here: https://youtu.be/_kiP6q8DX5c. The agent I spoke with walked me through exactly how to coordinate W-4s with my spouse.

•How does this even work? Sounds kinda sketchy... are you giving them your personal info just to talk to the IRS?

•Yeah right. NOBODY gets through to the IRS that fast. I've literally called dozens of times and waited hours only to get disconnected. I'm extremely suspicious of any service claiming they can get you through that quickly.

•It's actually not sketchy at all. They don't need any of your personal tax info - the service just navigates the phone system and waits on hold for you. When an agent is about to pick up, they call you and connect you directly to the IRS agent. It's basically just a sophisticated hold-your-place-in-line system. I was super skeptical too until I tried it. The IRS wait times are ridiculous right now - regularly 2+ hours if you can even get in the queue. This service just does the waiting for you so you don't have to keep your phone tied up all day. When I used it, I actually got connected in about 15 minutes, which was shocking after my previous attempts.

OK I feel like I need to eat my words here. After being completely skeptical about Claimyr, I decided to try it as a last resort because I was desperate for W-4 help after my company switched payroll systems. I was SHOCKED when I got a call back in 17 minutes saying an IRS agent was on the line. The agent explained that my wife and I had been filling out our W-4s all wrong for years (we were both claiming our kids) and walked me through exactly how to fix it. Probably saved us thousands in surprise tax bills. I'm still surprised it actually worked after all my failed attempts to reach someone.

The way we handled this with me and my wife was to do some math based on our incomes. Since she makes about 60% of our household income, she claims our daughter on her W-4 and I don't. That way the withholding roughly matches our actual tax situation. If you both make about the same, you could potentially split it by having one of you claim the child tax credit and the other claim an extra deduction amount. Just don't double dip or you'll be paying at tax time!

•But doesn't the new W-4 let you just put the number of dependents in Step 3? I thought they got rid of allowances altogether? I'm so confused by the new form.

•You're right that the new W-4 eliminated the concept of allowances. Now you directly enter the dollar amount of tax credits you expect to claim. For a qualifying child under 17, that's currently $2,000 per child. The key point is that if both you and your spouse put $2,000 in Step 3 of your respective W-4s for the same child, your combined withholding would account for $4,000 in tax credits when you're only eligible for $2,000. That's why coordination is important - you could each put $1,000, or one person could put the full $2,000 and the other zero.

I made this mistake last year with my husband and we ended up owing $4,200 at tax time!!! It was a nightmare. We both put our twins on our W-4s and our withholding was way too low. We had to set up a payment plan with the IRS. Learn from our mistake and just have one person claim the kids on their W-4!!

•Did you get hit with any penalties for underpayment? I'm worried about that part specifically.

•Yes, we did get hit with an underpayment penalty - it was about $180 on top of the $4,200 we owed. The penalty kicks in if you don't pay at least 90% of your current year tax liability or 100% of last year's tax (whichever is smaller) through withholding and estimated payments. Since we were so far off because of the double W-4 claiming, we fell way short of both thresholds. Definitely make sure you're withholding enough to avoid this situation!

This is a really common confusion! The key thing to understand is that the W-4 is about withholding the right amount of taxes from your paychecks throughout the year, not about who gets to "claim" your child on your actual tax return. Since you're married filing jointly, you'll both benefit from having your daughter as a dependent when you file your return regardless of your W-4 setup. However, if you both put your child's credit amount ($2,000) in Step 3 of your W-4s, you'd be telling your employers to withhold $4,000 less in taxes combined - but you're only entitled to one $2,000 child tax credit. This would likely result in underwithholding and you'd owe money at tax time. The best approach is to coordinate your W-4s. Since you both make similar incomes (~$58k each), you could either have one of you claim the full $2,000 child tax credit and the other claim zero, or you could each claim $1,000. I'd recommend using the IRS Tax Withholding Estimator at irs.gov to run the numbers and see what works best for your specific situation. Don't worry - this trips up a lot of couples! The important thing is making sure your combined withholding matches your actual tax liability.

•This is such a helpful explanation! I'm in a similar situation and was making the same mistake. Quick question though - when you mention using the IRS Tax Withholding Estimator, do you need to have your most recent pay stubs handy? And does it work if one spouse's income varies throughout the year due to overtime or bonuses? I want to make sure I get this right from the start rather than learning the hard way like some others here!

•Yes, having recent pay stubs is really helpful for the IRS Withholding Estimator! It asks for your year-to-date earnings and withholdings, so the more accurate your numbers, the better the recommendation. For variable income due to overtime or bonuses, the estimator can still work well. You'll want to estimate your total expected income for the year, including any bonuses or overtime you anticipate. If your income varies significantly, you might want to run the calculator a couple times during the year to adjust your W-4s as needed. The estimator also lets you see how different withholding scenarios would play out, so you can choose whether you want to aim for a small refund, break even, or owe a small amount. Since you're being proactive about this, you're already ahead of the game!

Great question! This is exactly the kind of confusion that trips up many married couples filing jointly. The short answer is: you should NOT both claim your daughter on your separate W-4 forms. Here's why: When you both claim the same child on your W-4s, you're essentially telling both of your employers to withhold less tax from your paychecks because you each expect to receive the $2,000 child tax credit. But since you're filing jointly, you'll only receive ONE $2,000 credit for your daughter - not two. This means you'll have underwitheld taxes throughout the year and likely owe a significant amount when you file. With your similar incomes ($58k each), I'd recommend one of these approaches: 1. One spouse claims the full $2,000 child tax credit in Step 3 of their W-4, the other claims $0 2. Each spouse claims $1,000 in Step 3 (splitting the credit) The IRS Tax Withholding Estimator tool on irs.gov is perfect for your situation - just plug in both of your income info and it will tell you exactly how to fill out both W-4s to get close to the right withholding amount. This way you avoid both owing too much or getting a huge refund (which is essentially an interest-free loan to the government). Your coworker was right that coordination is key, but it's not that "only one parent can claim" - it's that the total credits claimed across both W-4s shouldn't exceed what you'll actually get on your joint return.

•This is exactly the kind of clear explanation I needed! I'm in a very similar boat - married filing jointly for the first time with a 3-year-old son. I was about to make the same mistake of both my husband and I claiming our child on our W-4s. Quick follow-up question: if we decide to split it ($1,000 each in Step 3), do we need to do anything special when we actually file our joint return next year, or does it all just work out automatically since we're filing together? I want to make sure there's no extra paperwork or complications down the road. Also, thanks for mentioning the IRS Withholding Estimator - I had no idea that tool existed! Definitely going to use that this weekend to get our W-4s sorted out properly.
