Confused about filling out W-4S form for disability payments
Hey everyone, I'm starting physical therapy next month after a pretty serious sports injury and will be on disability leave for a while. My employer uses MetLife for our short-term disability coverage, and I'm trying to get everything sorted out before my leave starts. I just filed my claim with MetLife, but they sent me a W-4S form (Request for Federal Income Tax Withholding from Sick Pay) to complete. From what I've read, if a third-party like MetLife is paying your sick pay, you're not actually required to have federal income tax withheld by them. I understand this means I'm not *required* to have taxes withheld, but I'm thinking I probably should, otherwise I might end up owing a bunch when I file my taxes for 2025. The form instructions say, "Must be at least $4 per day, $20 per week, or $88 per month based on your payroll period." I'm assuming this is talking about the minimum amount they can withhold. But if I'm not required to have them withhold anything, does this minimum still apply to me? I'm really lost on how to approach this. Any advice would be super helpful!

This is actually a common question when dealing with third-party disability payments. You're right that you're not required to have taxes withheld from STD payments by third-party providers like MetLife, but it's almost always a good idea to do so. The language about "$4 per day, $20 per week, or $88 per month" refers to the minimum amount that can be withheld if you choose to have withholding. If you decide not to have any withholding, you can ignore those minimums. Here's what I usually recommend: Calculate roughly what your tax rate is on your regular paycheck (total federal tax withheld divided by gross pay) and request approximately that same percentage for withholding on your disability pay. This helps avoid a surprise tax bill when you file next year. Keep in mind that disability payments are generally taxable income, so if you choose not to have taxes withheld now, you'll need to either make estimated tax payments quarterly or be prepared to pay the full amount when you file your 2025 taxes.

•Thanks for the explanation! So if I decide to have taxes withheld, I need to request at least the minimum amount mentioned on the form, right? If I normally have about 18% withheld from my regular paychecks, should I just request that same percentage on the W-4S?

•Yes, if you decide to have taxes withheld, the amount must meet those minimums based on your payment schedule. Requesting the same percentage that's normally withheld from your regular paychecks (18% in your case) is an excellent approach. This helps maintain consistency in your tax situation and minimizes the chance of owing a large amount when filing. Remember that your disability payments will likely be lower than your regular salary, so even with the same withholding percentage, the actual dollar amount withheld will be less than what you're used to seeing on your regular paychecks.

Just wanted to share my experience with this exact situation last year. I was struggling with my W-4S for Prudential disability payments and discovered https://taxr.ai which was super helpful for figuring out the right withholding amounts. I uploaded my W-4S form and my previous pay stubs, and it analyzed everything to give me the right numbers to use. The tool actually showed me that I needed to withhold a slightly higher percentage on my disability payments than my regular paychecks to avoid owing money at tax time. Something about how disability payments are taxed differently. Definitely check it out if you're still confused about the form. It saved me from making a costly mistake on my withholdings.

•How exactly does this tool work? Does it ask for personal info like SSN? I'm in a similar situation with Liberty Mutual and really need help figuring out my withholding.

•I'm a bit skeptical. How is this any better than just calling the IRS helpline and asking them directly? Seems like another unnecessary middleman.

•The tool works by analyzing your tax documents and calculating the optimal withholding based on your specific situation. It doesn't ask for SSN - just the income information from your paystubs and the disability payment details. It then calculates the right withholding percentage considering how disability payments are taxed. Unlike calling the IRS helpline (which can take hours to get through), this gives you immediate answers. The IRS representatives also typically won't give specific withholding advice - they'll just explain the form rules. This actually calculates the numbers for your specific case, which is much more helpful than general guidance.

Following up on my question about taxr.ai - I tried it yesterday and it was exactly what I needed! I was completely lost with my Liberty Mutual W-4S form and wasn't sure what withholding percentage to use. The tool analyzed my current income tax situation and showed me that I needed about 22% withholding on my disability payments to stay on track with my tax obligations. It explained that because I wouldn't have 401k contributions coming out of my disability pay, I needed a slightly higher withholding rate than my regular paychecks. Just submitted my W-4S with the correct numbers and feel much more confident now. Definitely worth checking out if you're confused about disability tax withholding like I was.

For anyone still struggling with getting clear answers about their W-4S questions, I highly recommend using Claimyr (https://claimyr.com) to actually speak with an IRS representative. I tried calling the IRS directly about my W-4S questions last month and spent hours on hold with no luck. With Claimyr, I got through to an actual IRS agent in about 15 minutes who walked me through exactly how to fill out my W-4S for my Cigna disability payments. They have this service that basically waits on hold for you and calls you back when an agent is available. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c The IRS agent explained that for my specific situation (I have multiple income sources), I needed to approach the withholding differently than the standard advice. Saved me from a major headache at tax time.

•How does this even work? Why would they call you back faster than if you just called yourself? Seems fishy.

•Yeah right. I've tried "services" that claim to get you through to the IRS faster and they never work. The IRS phone system is deliberately designed to be impossible. I'll believe it when I see it.

•It works because they use technology that continuously calls the IRS and navigates the phone tree until it gets through to an agent. When an agent answers, their system connects you to the call. You're not actually getting "priority" - they're just doing the waiting for you. The IRS phone system isn't deliberately designed to be impossible - it's just understaffed and overwhelmed. This service simply handles the frustrating waiting part. I was skeptical too until I tried it. I got through to an actual IRS tax law specialist who answered all my specific W-4S questions about third-party sick pay. Much better than guessing or relying on internet advice for something this important.

I need to eat my words and apologize to Profile 9. After reading your comment about Claimyr, I decided to try it yesterday when I was completely stuck on how to handle my MetLife disability withholding. I've literally NEVER been able to reach the IRS by phone before, but with this service I got through to an agent in about 20 minutes. The agent confirmed that I didn't have to have taxes withheld from my third-party disability payments but strongly recommended that I do. She gave me specific guidance based on my particular situation (I have rental income and disability payments). For anyone struggling with W-4S questions - especially complicated situations - getting direct guidance from the IRS is actually the best approach. I'd tried for weeks to figure this out on my own and was getting nowhere.

Another option is to just set aside the money yourself instead of having it withheld. that's what i did last year when i was on disability. just calculated roughly 20% of each payment and put it in a separate savings account. then when tax time came around, i had the cash ready to pay what i owed. the advantage is you earn a little interest on the money throughout the year instead of giving the government an interest-free loan. the disadvantage is you need the discipline to not touch that money.

•But isn't there a penalty if you don't pay enough throughout the year? I thought there was some rule about having to pay at least 90% of your taxes during the current tax year.

•Good point about the potential penalty. You're thinking of the "safe harbor" rule. Generally, you need to pay either 90% of your current year tax or 100% of your previous year's tax (110% if your income is over a certain threshold) to avoid an underpayment penalty. If you're only on disability for a few months, you might be fine because your regular job withholding earlier in the year might cover enough of your total annual tax obligation. But if you're on disability for a longer period or for the full year, you'd need to make estimated quarterly tax payments to the IRS to avoid penalties. So, yeah, my suggestion works but requires more active management than just setting up withholding.

I'm in a similar situation with Guardian disability and something important to consider - your disability payments are likely LOWER than your regular salary. This means even if you withhold the same percentage as your regular job, you're actually withholding less money total. For example, if your regular job paid $4000/month and you withheld 20% ($800), but your disability only pays $2500/month with the same 20% withholding ($500), you're withholding $300 less per month. Over several months, this can add up to a significant tax bill if you're not prepared.

•This is super important! When I was on STD last year, my payments were about 60% of my regular salary, and even though I had withholding set up, I still ended up owing about $1,500 at tax time because of exactly this issue.

Great thread with lots of helpful insights! I went through this exact situation with my Aetna disability payments earlier this year. One thing I'd add is to check if your employer continues any benefits during your disability leave that might affect your tax situation. In my case, my company continued paying their portion of my health insurance premiums, which meant I had less taxable income than I initially calculated. This actually reduced the amount I needed to have withheld. I had to adjust my W-4S form mid-way through my leave to avoid over-withholding. Also, if you're planning to return to work part-way through the tax year, remember that your regular paycheck withholding will resume, so you don't want to double up and have too much withheld overall. I used a simple spreadsheet to track my total projected income and withholding across both my disability payments and expected regular paychecks for the remainder of the year. The key is looking at your total annual tax picture, not just the disability payment period in isolation.

This is such a helpful discussion! I'm dealing with a similar W-4S situation right now with my Aflac disability coverage. One thing I learned from my tax preparer that might be useful - if you're married filing jointly, make sure to consider your spouse's income and withholding when determining your disability withholding rate. In my case, my spouse's regular paycheck withholding was already covering a good portion of our combined tax liability, so I didn't need to withhold as much from my disability payments as I initially thought. We calculated that withholding about 15% from my disability pay (compared to the 22% from my regular paychecks) would keep us on track. Also, don't forget that if you're paying for your own disability insurance premiums with after-tax dollars, those payments are generally not taxable when you receive them. But if your employer pays the premiums (which sounds like your case with MetLife), then the benefits are taxable. This distinction can significantly impact how much you need to withhold.

•This is really helpful information about spousal income considerations! I hadn't thought about how my partner's withholding might affect my disability withholding calculations. We file jointly, and she has a steady job with consistent withholding, so this could definitely change the math for me. Quick question - when you mention that employer-paid premiums make the benefits taxable, does this apply even if I contribute part of the premium cost through payroll deduction? My employer pays most of my MetLife premium, but I think I pay a small portion post-tax. Does this create a partial tax situation, or is it all-or-nothing based on who pays the majority? Thanks for bringing up the spousal consideration - I'm definitely going to factor that into my calculations now!
