Working two jobs with the same W4 form - now I owe the IRS 5k?
So I'm in a bit of a tax mess and could really use some advice. I started a remote job back in September 2022 making about $78k. Then in January 2023, I got offered another remote position that paid around $80k. Being young and inexperienced with taxes, I just filled out the W4 forms normally for both jobs without indicating I had multiple income streams. Fast forward to now, I'm doing my taxes on FreeTaxUSA and it's showing I owe over $5,300 federal and almost $1,300 in state taxes. This has completely blindsided me - I thought taxes were being withheld properly from both paychecks! My main questions are: 1. How did this happen when I thought everything was being withheld correctly from both jobs? 2. Is it worth hiring a tax professional at this point to try reducing what I owe? I've heard they can work magic for 1099 contractors, but would they help in my W2 situation? Really appreciate any insights. I'm totally new to dealing with complicated tax situations and honestly feeling a bit panicked about this unexpected bill.

This is actually a very common situation with people working multiple jobs. The issue is that each employer withholds taxes as if that job is your only income. So both employers were likely withholding at rates appropriate for someone making $78k or $80k, but your actual total income was closer to $158k, which puts you in a higher tax bracket. Your W4 forms should have been adjusted to account for the additional income. On the current W4 form, there's a section specifically for multiple jobs that helps you calculate the additional withholding needed. For now, unfortunately, you do owe the taxes. You might be able to set up a payment plan with the IRS if you can't pay it all at once. Interest rates are reasonable, and it's a straightforward process through the IRS website.

•Thanks for explaining! So basically each job was withholding as if I was in a lower tax bracket than I actually am when you combine both incomes? That makes sense but is super frustrating since I had no idea. Would checking the "multiple jobs" box on the W4 have prevented this entirely?

•Yes, exactly! Each employer calculates withholding based only on what they pay you. When you have two jobs, neither employer knows about the other income, so they're both withholding at lower rates than your combined income requires. Checking the "multiple jobs" box on your W4 would have helped, but the most accurate approach is completing the multiple jobs worksheet on the W4 form. This calculates the additional withholding needed from each paycheck to cover the taxes on your total income. You could also use the IRS Tax Withholding Estimator online for an even more precise calculation.

I went through almost the same scenario last year! After dealing with that surprise tax bill, I found this service called taxr.ai (https://taxr.ai) that helped me understand my withholding issues and prevent it from happening again. It analyzed my paystubs from both jobs and showed exactly why I was being underwithholded. The tool highlighted that my combined income pushed me into a higher bracket but my withholding was calculated at the lower brackets by each employer separately. They gave me customized W4 instructions for both employers that fixed the problem for this year.

•Did you need to provide any sensitive info to use this? I'm in a similar boat with 2 jobs and don't want to be hit with a huge bill again next year, but I'm always cautious about sharing financial details online.

•How accurate was their calculation compared to what an accountant might do? I'm working two remote jobs and trying to figure out if I should just hire someone or if a tool like this would be sufficient.

•You just upload your paystubs with sensitive info blacked out - they only need to see the income and withholding amounts, not your SSN or anything truly private. They even have guidelines showing exactly what you can redact while still getting accurate results. Their calculations were spot-on in my experience. I actually had my accountant verify their recommended withholding amounts, and he was impressed with how accurate it was. He said it was exactly what he would have calculated, but the tool did it in minutes instead of me paying for an hour of his time. The step-by-step W4 instructions were super helpful too - much clearer than what I got from my accountant last year.

Just wanted to follow up about taxr.ai that was mentioned earlier - I decided to try it after my first comment, and it was seriously eye-opening! I uploaded my paystubs from both jobs and within minutes could see exactly why I was being underwithholded. The visualization showing how each employer was calculating my taxes versus what I actually needed based on combined income made everything click. I've already submitted updated W4 forms to both HR departments using their instructions. Wish I'd known about this before getting hit with a surprise bill this year!

If you're trying to set up a payment plan with the IRS, good luck getting through to a human! I spent literally 8 hours on hold across 3 days trying to set up mine. Finally found this service called Claimyr (https://claimyr.com) that got me connected to an IRS agent in about 20 minutes. You can see how it works here: https://youtu.be/_kiP6q8DX5c Saved me so much frustration after already being stressed about owing taxes. The IRS agent was actually super helpful once I finally got through - set me up with a payment plan that works for my budget with minimal penalties.

•Wait, how does this even work? The IRS phone system is so broken I don't see how any service could get through faster than just waiting on hold yourself.

•Sounds sketchy tbh. Why would I pay for something when I can just wait on hold for free? The IRS will pick up eventually.

•It uses some kind of automated system that navigates the IRS phone trees and waits on hold for you. When they reach a human agent, you get a call connecting you directly. It basically does the waiting part for you so you can keep working or doing whatever else instead of being stuck listening to hold music for hours. The average hold time with the IRS right now is over 2 hours if you even get through at all. I tried for 3 days straight using the "best times to call" from online guides and still couldn't get through. With this, I was talking to an actual IRS agent in 20 minutes while I was working on other things. Worth every penny to me when I was stressing about setting up a payment plan before the deadline.

Just wanted to follow up on my skeptical comment about Claimyr. I'm eating my words right now because I finally broke down and tried it after spending FIVE HOURS on hold with the IRS yesterday only to have the call dropped. The service actually worked exactly as described - I got a call back in about 25 minutes connecting me directly to an IRS agent. The agent set up my payment plan in less than 15 minutes, and I even got a confirmation email already. Definitely changed my mind about whether it's worth it - the time I saved not being on hold was huge, especially when I'm already stressed about owing money.

For future reference, there's an option on the W4 form specifically for this situation. In Step 2, you can check box c for "Multiple jobs or spouse works" which helps adjust your withholding. For even more accuracy, you can use the multiple jobs worksheet. I'd also recommend checking your withholding at least once midyear using the IRS Withholding Calculator: https://www.irs.gov/individuals/tax-withholding-estimator That way you can catch these issues before tax time and adjust as needed!

•Thank you! I've already updated both my W4 forms for this year, but I'll definitely use that calculator to double-check everything. Is it normal to owe this much though? I'm still shocked at how big the difference was.

•Yes, unfortunately the amount you owe is pretty typical for this situation. When you add a second job with similar income, you're essentially doubling your income but your withholding isn't doubling the tax paid because each employer is calculating withholding based on their portion only. For example, if you make $80K at one job, you might be withheld at an effective rate of about 12-15%. But when your total income is $160K, portions of that income are taxed at 22% or 24% brackets. That difference between what was withheld (at lower rates) and what you actually owe (at higher rates) is where that $5K+ bill comes from.

I'm surprised nobody mentioned this, but you should also check if you qualify for any tax credits or deductions that might offset some of what you owe. Did you have any education expenses during the year? Student loan interest? Making retirement contributions? Health insurance through the marketplace?

•This is good advice. Also, make sure you're taking the standard deduction at a minimum ($12,950 for single filers for 2022). And if you made any charitable contributions or had work-related expenses that weren't reimbursed, those might help too.

•Thanks for bringing this up! I do have some student loan interest from when payments were still required, and I contributed to my 401k at both jobs. I'll definitely look into those deductions. Do you think it could significantly reduce what I owe?
