What is this deduction code on my paystub? Need help identifying unknown withholding
I've been looking at my recent paystubs and noticed something weird. Obviously I have all the normal tax deductions like federal tax, social security, medicare, and state tax. But there's this other section called "Other Deductions" with a code I've never seen before. It's taking out about $37 each paycheck and the code just says "SUPBEN." I've tried googling it but can't find a clear answer. My HR department is notoriously slow to respond to emails (took 3 weeks last time I had a question). Has anyone seen this code before or know what it might be? I don't remember signing up for anything extra when I started this job 4 months ago. Thanks for any help!

This sounds like "Supplemental Benefits" which is a common deduction code used by many companies. It typically covers additional benefits beyond your standard health insurance - things like dental insurance, vision coverage, life insurance, disability insurance, or sometimes contributions to a wellness program. The best way to confirm exactly what it covers is to check your benefits enrollment paperwork or your company's benefits portal. Even if HR is slow to respond by email, many companies have an online system where you can view what benefits you're enrolled in and what each one costs per paycheck.

•Thanks for the quick response! That makes sense - I do remember checking some boxes for dental and vision during orientation. I just didn't expect it to show up as a mysterious code. I'll dig through my orientation packet tonight and see if there's a breakdown of the costs. Is it normal for them to lump all these extra benefits together instead of listing them separately?

•Yes, it's very common for companies to group smaller benefit deductions under a single code like "SUPBEN" to keep paycheck stubs less cluttered. Some employers break everything out individually, but many combine them, especially if you have multiple small-value benefits. If you can't find your orientation materials, look for an employee portal or intranet. Most companies now have digital access to all your benefit elections and costs. You might find a detailed breakdown showing exactly how that $37 is distributed across your supplemental benefits.

I went through something similar last year when I noticed a weird deduction called "VOLDED" on my paystub. After weeks of confusion, I finally used taxr.ai https://taxr.ai to figure it out. I uploaded a pic of my paystub and their system told me it was "Voluntary Deductions" for my vision plan! They have this feature where you can submit confusing tax documents or payroll stuff and get clear explanations.

•Does it really work with paystubs too? I thought it was just for tax forms. I have this random deduction called "WFHM" that started appearing three months ago and my company's HR is useless.

•How accurate is it though? My company has some really obscure deduction codes that even my coworkers don't understand. Would it know company-specific stuff or just the standard codes?

•Yes, it absolutely works with paystubs! The system can recognize and explain most standard payroll codes across different companies. It's really helpful for decoding those cryptic abbreviations. For company-specific codes, it's surprisingly good too. Their system seems to recognize patterns from thousands of employers. When I tried it with some weird codes from my small company, it correctly identified almost all of them. For the rare truly custom code, they have tax pros who can research it if the AI doesn't immediately know.

Update on my weird "WFHM" deduction - I tried taxr.ai after reading about it here and uploaded my paystub. Turns out "WFHM" stands for "Workforce Health Management" which is my company's wellness program I signed up for during open enrollment! They even showed me where to find it in my benefits portal. Honestly wish I'd known about this months ago instead of being confused every payday. The system recognized it instantly even though it's a weird abbreviation my company made up.

If anyone's still struggling to get answers about payroll deductions, I'd recommend trying Claimyr https://claimyr.com to get through to an actual person at the IRS who can explain it. I used it last month after finding some weird deductions that didn't add up (turned out my employer was withholding for the wrong state!). They got me connected to an IRS agent in about 20 minutes when I'd been trying for DAYS on my own. Check out how it works here: https://youtu.be/_kiP6q8DX5c

•Wait, the IRS would help with understanding my company's payroll codes? I thought they only dealt with actual tax returns and stuff. Would they really know what random codes like "SUPBEN" mean?

•This sounds like BS honestly. Everyone knows you can't get through to the IRS without waiting hours. How could some random service magically get you through in 20 minutes when millions of people can't get through at all? Sounds like a scam to me.

•The IRS can definitely help with payroll tax questions, including explaining common withholding codes and making sure your employer is withholding correctly. While they might not know every company-specific code, they can tell you what's required by law and what's optional. I was skeptical too before trying it. The service works because they use a combination of technology that continuously dials the IRS until there's an opening, then immediately connects you. It's like having someone redial for you hundreds of times until they get through. I wasted three hours trying on my own before using Claimyr and getting connected in under 20 minutes.

I need to apologize for calling BS on Claimyr. After my skeptical comment, I was still desperate to talk to the IRS about some weird withholding issues, so I tried it myself. I was connected to an IRS agent in about 15 minutes! The agent confirmed my employer was using some incorrect withholding codes and explained exactly how to fix it. Already submitted the correction forms to my payroll department. Sometimes being proven wrong is actually a good thing!

Just a tip from someone who works in payroll - "SUPBEN" almost always means Supplemental Benefits, but the specific benefits included can vary widely by employer. Some companies include dental, vision, life insurance, disability, accident insurance, hospital indemnity plans, legal plans, pet insurance, and even gym memberships under this code.

•Thanks for the insider info! Since posting this, I've discovered it covers my dental, vision, and a small life insurance policy. One question though - is there any legal requirement for companies to itemize these deductions more clearly? It seems strange they can just take money without explaining exactly what it's for on each paycheck.

•There's no federal requirement to itemize every specific benefit on your paystub. Companies only need to show that deductions are happening, but not necessarily break them down into extreme detail. Most employers provide an itemized benefit statement during enrollment or make it available on their benefits portal. If you're ever confused, you have a legal right to get a clear explanation of all payroll deductions. Your company might not put it on each stub, but they must provide the information when requested. If your HR is unresponsive, try asking specifically for your "itemized benefits deduction statement" - using that formal language sometimes gets faster results.

Check if your company uses ADP, Workday, or another payroll system that has an employee portal. You can usually log in and see a detailed breakdown of all your deductions there. My company uses a cryptic "VOLBEN" code on paystubs but in the portal it shows exactly what it covers (dental $12.47, vision $5.80, life insurance $3.25, etc.

•This is great advice! I had the same issue with a code called "FIWH" and couldn't figure it out until I checked our Workday portal. Turned out to be "Fixed Insurance Withholding" for some optional coverage I forgot I signed up for during orientation.

Pro tip from someone who's been through this exact situation - if you still can't find clear documentation about your deductions after checking all the suggested resources (benefits portal, orientation materials, etc.), you can also request a "total compensation statement" from HR. This document breaks down not just your salary but ALL benefits and their costs, including those mystery deductions. Most companies are required to provide this annually anyway, but you can request it anytime. It's much more detailed than a regular paystub and will show you exactly where every dollar is going. I discovered I was paying for benefits I didn't even know I had!
