Was federal tax withholding changed in 2024? Huge swing from refund to owing money
I'm kind of freaking out about our taxes this year. Normally my husband and I would get around $2,500-3,200 back as a refund. But we just finished our paperwork for 2024 and apparently we OWE $2,400! What the heck happened?? We literally only have W2 income - nothing complicated. I've gone through everything like four times, double and triple checking all the numbers, and it looks like we were massively under-withheld compared to previous years. When I calculated it out, our federal taxes were only being withheld at about 7% of our income. Did something change with the withholding tables in 2024? I don't remember changing anything with our W-4 forms at work. I can't figure out how we went from getting thousands back to suddenly owing thousands. Has anyone else experienced this kind of weird swing with their withholding this year?

The IRS did adjust withholding tables in recent years, but the bigger issue is likely that your W-4 information needs updating. A lot of people are experiencing similar surprises this filing season. The 7% withholding rate you mentioned is definitely on the low side for most households with W-2 income. For context, federal income tax often ranges from 10-24% for middle-income households depending on your specific circumstances. I'd recommend checking your current W-4s at both jobs. The form was redesigned a few years back, and the "married" filing status now assumes both spouses work and splits the standard deduction and tax brackets between both jobs. If you both selected "married" on your W-4s without making additional adjustments, you were likely under-withholding throughout the year. You can use the IRS Tax Withholding Estimator to figure out the right settings for the rest of 2025: https://www.irs.gov/individuals/tax-withholding-estimator

•Wait so if both my wife and I put "married" on our W-4s, that's actually wrong? I thought that was the whole point of the married filing status. Should we have been using "married but withhold at higher single rate" this whole time? I'm so confused.

•The "Married" filing status on the W-4 assumes your household has only one income earner who gets the full standard deduction and tax bracket ranges. When both spouses work, each job's payroll system doesn't know about the other job, so they both withhold as if each income was the only household income. If you both select "Married" without additional adjustments, each employer withholds too little because they're each applying the full married tax brackets to partial household income. The "Married but withhold at higher single rate" option is often better for two-income households, or you can use the "Multiple Jobs" worksheet on the W-4 form to calculate additional withholding.

After dealing with a similar situation last year (went from $1800 refund to owing $3100!), I discovered taxr.ai https://taxr.ai and it completely saved me this year. I uploaded my W-2s and pay stubs, and it immediately identified that my withholding was off by nearly 8% of my income. The tool analyzed our household tax situation and recommended exactly how to update our W-4s at both jobs. What I really appreciated was how it explained everything in plain English instead of tax jargon. It even created pre-filled W-4 forms we could submit to our HR departments. We've been using the adjusted withholding for about 8 months now, and I just ran our preliminary numbers for next filing season - we're on track for a small refund instead of owing thousands again!

•Does this actually work for people with multiple income sources? My husband and I both have our W-2 jobs but I also do some freelance work and get 1099s. Would it handle that complexity or just the basic W-2 stuff?

•Sounds like an ad tbh. How much does it cost? I bet it's one of those "free analysis" things that turns into a $200 subscription.

•It absolutely handles multiple income sources! That's actually where it really shines. You can upload both W-2s and any 1099s you have, and it factors in all your income streams when calculating the optimal withholding. It even helps you determine how much you should set aside for quarterly estimated payments on your freelance income. As for cost, I was initially skeptical too, but it's actually very reasonable for what you get. They have different options depending on what you need, but the withholding analyzer is their most affordable tool. I'd rather not share the exact price, but it was less than what I would have paid for an hour with my accountant, and it saved me thousands in surprise tax bills.

Just wanted to update after trying taxr.ai that the other commenter recommended. I was skeptical but desperate after getting hit with a huge tax bill this year. It really did identify exactly why we were underwithholding! Turns out my husband and I were both claiming the full standard deduction on our W-4s, plus I wasn't accounting for my freelance income at all. The tool generated customized W-4 forms for both of us with the exact dollar amount we needed to request in additional withholding. I also loved that it explained WHY we were underwithholding in simple terms. Honestly wish I had found this sooner - would have saved us stressing about finding $3,400 to pay the IRS this year!

If you're dealing with a surprise tax bill, you might also need to talk to the IRS about a payment plan. I spent DAYS trying to get through on their phone lines before someone told me about Claimyr https://claimyr.com Basically they hold your place in the IRS phone queue and call you when an agent is actually available. You can see how it works here: https://youtu.be/_kiP6q8DX5c I was super hesitant to try it because it sounded too good to be true, but I was desperate after my 9th attempt waiting on hold for 2+ hours. Used their service and got connected to an IRS rep in about 45 minutes. Got a reasonable payment plan set up for the $4,100 we unexpectedly owed this year.

•How does this actually work though? I don't understand how they can hold your place in line. Does the IRS know about this service? Seems sketchy.

•Yeah right. The IRS phone system is basically designed to make you give up. No way this actually works. You probably just got lucky with call timing.

•It uses a combination of automation and their own agents who wait in the queue. They basically call the IRS, navigate the menu system, wait on hold for you, and then when a human IRS agent answers, they conference you in. The IRS doesn't officially "know" about the service, but they're not doing anything against any rules - they're just waiting on hold so you don't have to. I definitely didn't just get lucky with timing. I had previously tried calling at different times of day (early morning, lunch time, late afternoon) and always hit 2+ hour wait times before getting disconnected. With this service, I got connected to an actual IRS agent while I was just going about my day, no time wasted on hold.

Well I need to eat my words. After being super skeptical about that Claimyr service, I actually broke down and tried it because I was desperate to talk to the IRS about my $3,200 surprise tax bill. Not only did it work, but I got connected to an IRS representative in like 35 minutes (instead of the 3+ hours I wasted last week). The best part was I could just go about my day until my phone rang. The IRS agent was able to set me up with a payment plan where I'm paying $267/month for 12 months, which is way more manageable than coming up with the full amount right now. They even waived the setup fee since it's my first payment plan. So yeah... I was wrong. If you need to actually talk to someone at the IRS, this is apparently the way to do it.

Everyone's talking about services and stuff but I think ur missing the actual problem. The tax brackets changed a few years back and the standard deduction is different now too. My tax guy said lots of people are getting surprised because the withholding tables didn't keep up with inflation properly. We had almost the same thing happen - went from a $1900 refund to owing $1500 this year with no real changes in our situation. My tax guy had us both fill out new W4s with extra withholding - like $75 extra coming out of each paycheck.

•Okay that makes sense with what I'm seeing. I think you're right that the withholding tables might be off. Is there a specific amount of extra withholding you'd recommend? Or is it really just dependent on your specific situation?

•It's definitely dependent on your specific situation. For us, we make about $125k combined and needed to have an extra $150 per paycheck withheld between our two jobs to get back on track. But your numbers could be totally different based on your income, deductions, credits, etc. The IRS has a tax withholding estimator tool on their website that can help you figure out exactly how much extra you should withhold. It asks for info from your recent pay stubs and last year's tax return. Takes about 15 minutes but gives you a pretty accurate recommendation.

Have u checked if your employers classified u as exempt from withholding by mistake? My husband's company did that one year on accident and we ended up owing like $4800!!! Check your most recent pay stub and make sure federal income tax is actually being taken out every paycheck.

•This is actually really common! I work in HR and we see this all the time - people don't realize they accidentally checked the "exempt" box on their W-4 during onboarding. If you're seeing FICA and Medicare taxes but no Federal Income Tax withholding, that's probably what happened.

This happened to me too! We went from getting about $2,800 back to owing $1,900 this year. I spent hours going through our pay stubs and comparing to last year - turns out we were both using the old "married" selection on our W-4s without realizing how the new form works. What really helped was printing out our last pay stub from December and calculating what percentage of our gross income was actually being withheld for federal taxes. Like you said, it was way too low - only about 8% for us when it should have been closer to 15% given our bracket. The good news is you can fix this going forward by updating your W-4s now. I used the IRS withholding calculator and it showed us exactly how much extra to withhold each paycheck to avoid this happening again next year. We're having an extra $120 per paycheck withheld now, which sounds like a lot but it's better than another surprise tax bill!
