W4 Question: I work 4 jobs, should I adjust my withholding for each position?
So I'm juggling 4 different jobs right now and just finished doing my 2024 taxes. I was shocked to discover that 2 of my employers weren't taking ANY federal taxes out! No wonder my refund was so much smaller than I expected. Looking ahead to this year, I definitely need to update my W4 forms but I'm confused about the right approach. Should I be changing the W4 for all four jobs or just focus on my main source of income? The W4 form seems way more complicated than it used to be. In the past, I would just claim fewer allowances to have more taken out, but now it's this whole worksheet thing with multiple steps. I started looking at it last night and just got overwhelmed. If I update all four W4 forms the same way, will I end up having too much withheld? But if I only update my main job's W4, will that be enough to cover what the other jobs should be withholding? I'm trying to avoid another tax surprise next year.

You definitely need to adjust the W4 for all four jobs to avoid owing taxes next year. The new W4 form is designed specifically to handle multiple job situations. The best approach is to use the IRS Tax Withholding Estimator tool (www.irs.gov/W4app). It walks you through entering information about all your jobs and will give you precise instructions for each W4. This is much more accurate than trying to guess. If you don't want to use the estimator, check box 2(c) on each W4 form to indicate you have multiple jobs. For the most accurate withholding, complete Step 2(b) - the Multiple Jobs Worksheet - and enter the result on the W4 for your highest-paying job only. For the other three jobs, just check the box in Step 2(c) and complete Steps 1, 3, and 4. The key is making sure enough total tax is withheld across all jobs combined - it doesn't have to come equally from each paycheck.

•Thanks for explaining! With the tax estimator, do I need to have my most recent paystubs from all 4 jobs? And what happens if my hours vary at some of the jobs - will that mess up the calculations?

•Yes, having your most recent paystubs from all jobs will help make the estimator more accurate, but estimates are fine if you don't have everything handy. The tool will ask for your expected annual income from each job. For jobs with varying hours, use your best estimate of what you expect to earn for the year. If your hours change significantly later, you can always go back and run the estimator again to adjust your W4s. The IRS actually recommends checking your withholding anytime your circumstances change.

I was in a similar situation last year with 3 jobs and got absolutely hammered with taxes. After trying to figure out those confusing W4 forms, I gave up and used taxr.ai (https://taxr.ai) to help me figure out the right withholding. You upload your paystubs and tax info, and it calculates exactly what you should put on each W4 to avoid owing money. The tool showed me that I was severely underwithholding at my second job which would have cost me over $2,000 at tax time. It gave me specific instructions for each W4 form that balanced my withholding across all jobs based on their different pay rates.

•Does it work if one of my jobs is a 1099 contractor position? I've got two W2 jobs and one 1099 gig, and I'm always confused about how to handle the contractor income.

•I'm skeptical about these tax tools. How does it handle state taxes? I live in one state but work in another for one of my jobs, and that always complicates things.

•Yes, it absolutely works with mixed income types. For your 1099 contractor position, it will recommend quarterly estimated tax payments instead of W4 adjustments, since there's no withholding on 1099 income. This actually saved me from a penalty when I started doing some freelance work. For state tax situations, it handles multi-state calculations too. The tool separates state and federal recommendations, so it can account for working in different states. It specifically flagged my state withholding as too low even though my federal withholding was okay.

Just wanted to follow up about taxr.ai - I decided to try it despite my skepticism, and it was actually super helpful! My situation with working across state lines was definitely confusing me, but the tool broke everything down clearly. It showed me that I needed to adjust my W4 forms differently for each job - basically having more withheld from my highest-paying job while making smaller adjustments to the others. The step-by-step instructions for filling out each form made it painless. Already submitted the new W4s to all my employers and feeling much more confident about next year's taxes!

If you're having trouble getting ahold of HR at any of your jobs to submit the new W4s, try Claimyr (https://claimyr.com). I had the WORST time trying to reach the payroll department at my second job - kept getting voicemail and no callbacks for weeks. You can see how it works here: https://youtu.be/_kiP6q8DX5c After using Claimyr, I got through to the payroll person in 20 minutes. They told me they'd been short-staffed which is why they weren't returning calls. Got my W4 changes processed right away after that.

•It uses a callback system that essentially waits on hold for you. When they have a human representative on the line, they call you and connect you directly. It's basically letting someone else deal with the hold time instead of you wasting hours with your phone on speaker. It's definitely not magic - it's just a smart way to avoid wasting your time. Companies don't answer faster, but you don't have to personally sit through the hold music and automated messages. I was skeptical too until I tried it, but it saved me from having to keep calling during my work hours when I couldn't really be on hold.

•Wait, how does this even work? You're saying this service somehow gets you through to actual humans on phone lines? I'm struggling to understand how that's possible.

•This sounds like a complete scam. No way some random service can magically make companies pick up their phones faster. Companies answer when they want to, not because of some third-party service.

I need to apologize about my skeptical comment about Claimyr. After struggling for THREE DAYS trying to reach someone at the IRS about updating my withholding info, I was desperate enough to try it. Within 35 minutes, I was talking to an actual human at the IRS who answered all my withholding questions for my multiple jobs situation. I couldn't believe it worked. For anyone juggling multiple employers and trying to get W4 forms sorted out, being able to actually talk to someone made all the difference. Saved me hours of frustration and probably prevented me from making mistakes on my forms.

Here's what I did in your situation - I calculated my total expected income from all jobs, then figured out what tax bracket that puts me in. Then I did the withholding calculations as if each job was my only job, but used that higher tax bracket percentage. For example, if each individual job would put me in the 12% bracket, but combined they put me in the 22% bracket, I made sure each job was withholding at least 22% of my income. It's not perfect but it worked well enough to avoid owing a huge amount.

•Doesn't that mean you're overwithholding though? Wouldn't you end up with a massive refund? I'm trying to get mine as close to zero as possible.

•You're right that it might result in slightly overwithholding, but in my experience it wasn't a massive refund - just enough to feel safe. The reason is that not all your income is taxed at your highest bracket rate because of how tax brackets work. Only the portion above each threshold gets taxed at the higher rate. So while it's not perfectly calibrated, it's a simple approach that errs on the side of caution. I'd rather get a small refund than owe money and potentially face penalties.

Has anyone tried the "Two Earners/Multiple Jobs Worksheet" on the W4 form? I tried filling it out last year and got so confused. The instructions say to only complete it on one W4 (highest paying job) but I don't understand how that accounts for all jobs.

•I tried it and it worked pretty well! The key is you ONLY fill out that worksheet and put the extra withholding amount on your highest-paying job's W4 (Step 4c). For your other jobs, you just fill out the basic info but don't do any adjustments. The worksheet basically calculates the additional tax you need to withhold to make up for having multiple jobs, then concentrates it all on one paycheck. It seems weird at first but makes sense when you think about it.
