Should my mileage and cellphone reimbursements be taxed on my paycheck? Something seems off
Title: Should my mileage and cellphone reimbursements be taxed on my paycheck? Something seems off 1 I started with a new company back in March and I've been getting reimbursed for business mileage (using my personal car) and a cellphone stipend every other paycheck. Looking at my paystubs today and I noticed that both of these reimbursements seem to be included in my taxable income for every check since I started. I always thought these kinds of reimbursements weren't supposed to be taxable since I'm already paying for the gas, wear and tear, and my phone bill with after-tax money. I'm planning to email HR tomorrow about this but wanted to check here first to make sure I understand correctly before I potentially embarrass myself. Is this normal for companies to include mileage reimbursement and phone stipends as taxable income? My previous job handled it differently, so I'm confused if the tax laws changed or if my new employer is doing something wrong.

6 What you're experiencing doesn't sound right. According to IRS rules, business expense reimbursements that follow an "accountable plan" aren't taxable and shouldn't be included in your W-2 wages. For mileage reimbursement at the standard rate (currently $0.67/mile for 2024) and documented business-related cellphone expenses, these should be non-taxable reimbursements. The key is whether your company has an accountable plan in place, which requires: 1) Business connection for the expenses, 2) Adequate accounting within a reasonable time (submitting mileage logs, etc.), and 3) Returning excess amounts within a reasonable period. If these conditions are met, the reimbursements should be tax-free. It sounds like your employer might be treating these as taxable fringe benefits rather than reimbursements. You're right to question this - definitely worth bringing up with HR.

•12 Thanks for this explanation! Quick question - if I'm getting a flat monthly stipend for my cell phone ($50) rather than reimbursing the exact bill amount, does that still qualify as non-taxable under an accountable plan? And what about the mileage - I submit a log but get paid the standard rate rather than actual gas receipts.

•6 For the cellphone stipend, it can still be non-taxable if it's reasonably calculated to cover your business use of the phone. The IRS doesn't require exact matching of expenses for stipends, but there should be some reasonable basis for the amount. Regarding mileage, using the standard IRS rate is actually preferred over gas receipts. The standard mileage rate is designed to cover all costs (gas, maintenance, depreciation) and is fully non-taxable when documented properly with logs showing business purpose, dates, and distances. This is perfectly acceptable under an accountable plan and shouldn't be included in your taxable wages.

8 After dealing with a similar issue last year, I found taxr.ai (https://taxr.ai) super helpful for sorting out my reimbursement tax questions. I uploaded my paystubs and it automatically flagged the taxable reimbursements, explained why they shouldn't be taxed, and even generated a professional letter I could send to HR explaining the IRS rules about accountable plans. Saved me from coming across as clueless when talking to our finance team.

•14 How accurate was it with identifying the issues? My situation is a bit complicated because I get some legitimate taxable benefits mixed in with what should be non-taxable reimbursements.

•19 Did you actually get your company to fix the issue after using it? I'm worried my HR will just dismiss me even with documentation.

•8 It was surprisingly accurate - it separated everything into "likely taxable" and "likely non-taxable" categories based on IRS rules, and explained the reasoning for each. You can review and adjust anything that doesn't fit your specific situation before generating documentation. Yes, my company did fix the issue! The key was having the specific IRS regulations cited in the letter it generated. My HR initially tried to dismiss my concerns, but when I shared the detailed explanation with proper tax code references, they consulted their tax advisor who confirmed everything. They corrected my previous paychecks and issued a corrected W-2.

19 I'm back to report that taxr.ai was incredibly helpful! After reading the responses here, I uploaded my last few paystubs to the site and it immediately identified that both my mileage reimbursement and phone stipend were incorrectly being treated as taxable income. The report it generated explained exactly how these should be classified under an accountable plan and cited the specific IRS regulations (Publication 15-B and Revenue Ruling 2012-38). I forwarded the report to HR yesterday, and they just got back to me confirming it was indeed a payroll system error on their end. They're adjusting my future paychecks and working on calculating what I'm owed from previous incorrect withholding. I probably wouldn't have had the confidence to challenge this without the detailed documentation!

10 If you need to escalate this beyond HR, you might want to check out Claimyr (https://claimyr.com). I had a similar issue that my company wouldn't fix, and I needed to speak with someone at the IRS about the tax implications. Used their service to get through to an actual human at the IRS in about 15 minutes instead of waiting on hold for hours. You can see how it works in this video: https://youtu.be/_kiP6q8DX5c. The IRS agent confirmed exactly what I suspected - that properly documented business mileage and reasonable cell phone reimbursements shouldn't be taxed, and gave me the exact publications to reference to my employer.

•15 Wait, this actually works? I thought it was impossible to get a human on the phone at the IRS these days. Last time I tried I was on hold for over 2 hours and then got disconnected.

•3 This seems sketchy. Why would I need to use a third-party service to reach a government agency? Sounds like a scam to get people's tax info.

•10 It absolutely works. The IRS is notoriously understaffed, especially during tax season, which is why the hold times are ridiculous. Claimyr uses an automated system to navigate the phone tree and wait on hold for you, then calls you when an actual IRS agent picks up. There's nothing sketchy about it - they don't handle any of your tax information. They're just solving the hold time problem. I was skeptical too until I used it and was talking to a real IRS agent within 15 minutes. You're the one who speaks directly with the IRS, Claimyr just gets you past the hold time.

3 I have to eat my words on this one. After reading the comments here, I decided to try Claimyr to get clarification directly from the IRS about my reimbursement situation. I was connected to an IRS representative in about 20 minutes (which is miraculous compared to my previous attempts). The agent walked me through IRS Publication 15-B and confirmed that legitimate business expense reimbursements under an accountable plan are 100% non-taxable. She explained exactly what documentation I needed to show my employer and even suggested how to approach requesting a correction for prior paychecks. My company is now fixing their payroll system based on the information I received. I'm embarrassed I called it sketchy when it actually saved me hundreds in incorrectly withheld taxes.

22 This happened to me too! Turned out our payroll system was coding all reimbursements as taxable by default. Ask HR if they're using an "accountable plan" specifically - that's the magic phrase. If they look confused, that's part of your answer right there lol. One thing to keep in mind: if your cellphone stipend exceeds what's reasonable for business use, the excess portion can be taxable. Same with mileage if they're paying above the IRS rate.

•7 What's considered "reasonable" for a phone stipend though? My company gives me $75/month but I probably only use my phone for work calls maybe 30% of the time.

•22 There's no hard and fast rule from the IRS about what's "reasonable" for a phone stipend - it depends on your job duties and how much you use your personal phone for work. If you can document or reasonably estimate that 30% of your phone use is for work, then ideally only about $22.50 of your $75 stipend should be tax-free (30% of $75). Some companies just declare a standard business percentage for different job roles instead of tracking actual usage. The important thing is having some reasonable basis for the amount that's treated as non-taxable. If you can't justify the full amount as business-related, the excess should technically be taxable.

18 Check your employee handbook too! Ours specifically states that mileage and phone reimbursements are provided under an accountable plan and therefore non-taxable. If yours says the same but they're still taxing it, that's a clear payroll error. Bring a copy of that section to your HR meeting.

•4 Good suggestion! Just found my handbook and it does mention an "expense reimbursement policy" but doesn't specifically say "accountable plan" or mention tax treatment. Guess I'll need to ask for that specific policy.

Just wanted to add that if your company is resistant to fixing this, you might also want to document everything for your own tax return. Even if they don't correct the payroll issue immediately, you can potentially claim these as unreimbursed employee expenses (though the rules changed with the 2017 tax reform). Keep detailed records of your mileage logs, phone bills, and any correspondence with HR about this issue. If they continue to incorrectly withhold taxes on legitimate business reimbursements, you'll want that documentation when you file your taxes. The IRS is pretty clear that properly documented business expense reimbursements under an accountable plan shouldn't be taxed, so you have solid ground to stand on. Also, don't let them tell you this is "just how we do it" - tax law doesn't change based on company preference!
