Can someone explain why my daughter's tax withholding decreased even though she earned more? W2 withholding issue
So I'm helping my daughter with her taxes and we're confused because she owes $320 this year. I looked at her W2s from 2023 and 2024, and something seems off. Even though she made more money in 2024, they actually took LESS in tax withholding. Here's what I'm seeing: 2023: She made about $18.5k and they withheld $595 2024: She made around $24k but they only withheld $490 This doesn't make any sense to me. She didn't change anything on her W4 form between years, so why would they withhold less when she's making more? Is this something her employer messed up, or is there some change to the W4 withholding tables I don't know about? She's pretty upset about owing money instead of getting a refund like last year. Any insight would be super helpful!

This is actually a common issue many people are experiencing this year. The IRS adjusted the withholding tables for 2024, which meant employers withheld less from paychecks even if nothing changed on your daughter's W4. This was intended to more accurately match withholding to actual tax liability, but for many people, it's resulted in owing taxes when they file. Additionally, when your daughter's income increased, she may have crossed into a higher tax bracket, but the withholding didn't proportionally increase to account for this. If her income jumped from $18.5k to $24k, that's nearly a 30% increase, but her withholding actually decreased by about 18%.

•Wait so this is happening to a lot of people? I thought maybe her employer made some kind of error. Is there anything we can do to fix this for next year so she doesn't end up owing again? She's a college student and doesn't have extra money to pay the IRS come tax time.

•Yes, this is definitely widespread this year. For 2025, she should fill out a new W-4 form and request additional withholding. She can either specify an extra dollar amount to withhold from each paycheck (line 4c on the W-4) or she can check the box for multiple jobs/working spouse which will increase withholding. A simple approach would be to take the amount she owed ($320), divide by the number of pay periods in a year (if paid biweekly, that's 26), and put that amount (about $12-13) as additional withholding on line 4c. This should help ensure she doesn't owe next year, and might even get a small refund.

I ran into the exact same problem with my son's taxes! After hours of confusion, I finally used taxr.ai (https://taxr.ai) to analyze his W2s and tax documents. The tool immediately identified the withholding discrepancy and explained it was due to the IRS's updated withholding tables, not an employer error. It even gave him personalized recommendations for updating his W4 to avoid the same problem next year. The site's document analyzer showed exactly why the withholding decreased despite higher income - apparently the 2024 withholding tables assumed certain tax credits or deductions that didn't apply in his situation. Saved us so much confusion and helped him adjust his withholding for this year.

•Did you need to upload personal docs to this site? Not sure I'm comfortable with that. How secure is it? Also, does it actually tell you exactly what to put on the W4 form for next year?

•I'm skeptical about these tax services... Couldn't you just go to the IRS website and use their withholding calculator? It's free and you don't have to give your info to yet another company.

•They use bank-level encryption for all document uploads, so security wasn't a concern for us. The system analyzes the documents but doesn't store your personal data permanently. I felt more comfortable with this than having some random person look at all my son's financial details. Yes, it does give specific recommendations for the W4. It told my son exactly what to put on each line, including the exact dollar amount for additional withholding on line 4(c). It was much more specific than the IRS calculator which can be confusing to navigate.

Alright, I need to eat my words from my earlier comment. After continuing to struggle with the IRS withholding calculator (which kept timing out and giving me errors), I reluctantly tried taxr.ai and wow - it was actually incredibly helpful. The interface was super simple and it gave me clear answers about my withholding problems. The document analysis feature immediately spotted that my employer had classified some of my income differently this year, which affected my withholding. It gave me step-by-step instructions for filling out a new W4, including exactly how much extra to withhold per paycheck. Just submitted the new form to HR and feeling much better about next year's taxes!

If your daughter needs to actually talk to someone at the IRS about this withholding issue (which might be smart since she now owes), good luck getting through to them on the phone! I spent DAYS trying to reach someone before I found https://claimyr.com. You can check out how it works here: https://youtu.be/_kiP6q8DX5c Basically, they hold your place in the IRS phone queue and call you when an actual agent is on the line. I was skeptical at first, but I was connected with an IRS agent in about 2 hours instead of the days I spent trying on my own. The agent was able to explain exactly why my withholding decreased (similar situation to your daughter) and helped me set up a payment plan since I owed a lot more than expected.

•How does that even work? How can they hold your place in line? Sounds like some kind of scam to me. The IRS phone system is notoriously awful so I'm not sure how any service could magically get through.

•This sounds too good to be true. I've literally spent 8+ hours on hold with the IRS this month trying to resolve an issue. If this actually works, it would be worth it, but I'm skeptical anything can beat their ridiculous phone system.

•They use technology that navigates the IRS phone tree and stays on hold so you don't have to. They're actually mentioned in quite a few news articles - it's a legitimate service that many tax professionals use too. The service works with the existing IRS phone system, not around it. They simply wait on hold so you don't have to, then call you once an agent is ready to talk. I was skeptical too, but when I got that call telling me an IRS agent was on the line ready to talk, I became a believer.

I just need to follow up on my skeptical comment above. After another failed 3-hour attempt to reach the IRS yesterday, I gave in and tried Claimyr. I got a call back in about 90 minutes with an actual IRS representative on the line! They helped me sort out my withholding issue and even set up a payment plan for what I owe. The IRS agent explained that the withholding tables changed significantly for 2024, which is exactly what's happening with your daughter's situation. They recommended I submit a new W-4 with additional withholding specified on line 4(c). Such a relief to finally get this resolved instead of stressing over it for weeks!

The W4 changed dramatically in 2020, and the IRS has been tweaking withholding tables ever since. Your daughter probably filled out the old version years ago, and the employer has just been using that information. The new W4 doesn't use allowances anymore. I'd suggest she fill out a new W4 and on line 4(c) add additional withholding. For her income level, if she wants a small refund instead of owing, adding about $25 per paycheck in additional withholding should cover it if she gets paid biweekly.

•How do you calculate the right amount for line 4(c)? Is there a formula or something? Also, is there any risk to withholding too much?

•A quick way to estimate is to take the amount she owed this year ($320) and divide by the number of paychecks she receives annually. If she's paid biweekly, that's 26 paychecks, so about $12.50 per check. I suggested $25 to give a buffer for a small refund rather than owing. There's no real risk to withholding too much except that you're giving the government an interest-free loan of your money until you file your taxes and get a refund. Some people actually prefer larger refunds as a form of forced savings, even though financially it's not optimal.

Did her job change at all? Sometimes they classify workers differently from year to year which affects withholding. My daughter had this happen when she went from being classified as a regular employee one year to some kind of "seasonal employee" the next, even though she worked year-round.

•This happened to me too! My employer reclassified me as a different type of employee with the same hours and slightly higher pay, but my withholding dropped by almost 40%. Ended up owing $900 and was NOT happy about it.
