Can I deduct non-prescription sunglasses as a business expense? Need help with IRS rules

Tax professional here. The confusion about sunglasses as a business deduction stems from the IRS rule that business expenses must be both "ordinary and necessary" for your trade or business to be deductible. For sunglasses specifically, the key question is whether they're specialized for your occupation or considered general personal items. In your case as a fishing guide spending all day on water, polarized sunglasses could potentially qualify since they serve a specific business function (reducing glare on water) that's directly related to your ability to perform your job safely and effectively. The IRS typically denies clothing deductions when items can be used for general/personal wear, but specialized equipment that's not suitable for everyday use has a stronger case. I'd recommend keeping detailed documentation: when you use them, how they're specifically needed for your business, and if possible, get something in writing from your eye doctor about their recommendation for your occupation.

After struggling with similar tax questions about specialized equipment for my outdoor adventure business, I found this amazing AI tool called taxr.ai (https://taxr.ai) that analyzes tax deduction scenarios based on your specific profession and situation. I uploaded details about my specialized gear including my high-end polarized sunglasses, and it gave me a detailed analysis of deductibility based on actual tax code and precedents. The tool showed me exactly which IRS publications supported my deduction and helped me understand the difference between "ordinary clothing" and "specialized equipment necessary for business" - which was the key distinction for my sunglasses. It even helped me draft the proper documentation to support my deduction if I'm ever audited.

I just wanted to follow up after trying taxr.ai for my landscaping business tax questions. I was skeptical at first, but I had several specialized equipment items (including UV-protective eyewear) that I wasn't sure about deducting. The analysis was surprisingly comprehensive! It broke down the "ordinary and necessary" test specifically for my industry and showed IRS examples where similar deductions were approved or denied. The documentation guidelines were super helpful - I never would have known to keep certain records that the tool suggested. Ended up saving over $800 in deductions I would have been too nervous to claim otherwise, with proper backup documentation for everything.

If you're dealing with IRS questions about business deductions that aren't clearly defined like these sunglasses, trying to reach someone at the IRS for clarification is almost impossible these days. I spent WEEKS trying to get through on their business tax line. Then I discovered Claimyr (https://claimyr.com) - they got me connected to an actual IRS agent in under 45 minutes! You can see how it works here: https://youtu.be/_kiP6q8DX5c I explained my situation about specialized equipment deductions and got clear guidance directly from the source. The agent explained exactly what documentation I needed to substantiate these types of "gray area" business expenses and what factors they look at when determining if something is truly a necessary business expense versus personal.

OK I need to admit I was completely wrong about Claimyr. After posting that skeptical comment, I decided to try it myself since I've been trying to get clarification on some business deductions for months with no luck. The service actually worked exactly as described. I put in my request around 9am, got a text update when they were waiting on hold, and then got connected to an IRS agent a little after lunch. The agent walked me through exactly what qualifies as "ordinary and necessary" for business equipment and gave me specific guidance on my sunglasses question (turns out in my case as a golf instructor, they're considered personal items unless prescription). Saved me so much time and frustration. Definitely worth it just for the hours of hold time I didn't have to deal with.

Just wanted to add something important here - if you do decide to deduct specialized sunglasses, make sure you have a separate pair for personal use! The IRS will be much more likely to deny the deduction if you only have one pair of sunglasses total, even if you claim they're only for work. I made this mistake a few years ago with some equipment. I claimed it was 100% for business but didn't own a personal version of the same item. The auditor specifically asked if I had separate items for personal use, and when I said no, that's what triggered the denial. Lesson learned!

Has anyone had success deducting UPF sun protective clothing for outdoor work? My dermatologist actually wrote me a note recommending specialty sun protective gear including hats and shirts since I work on boats all day. Wondering if the same "specialized equipment" rule might apply?

As someone who's been through multiple IRS audits for my marine equipment rental business, I can tell you that documentation is absolutely critical for these types of deductions. For your polarized sunglasses, I'd recommend creating a simple business use log - just date, hours worked, and brief description of conditions (like "8-hour charter, bright sun, open water"). The fact that you have separate personal sunglasses is huge in your favor. I also keep photos of my business-specific gear alongside receipts to show the difference between work and personal items. For sunglasses specifically, polarized lenses for water work have a much stronger case than regular tinted glasses since they serve a specific anti-glare function that's directly tied to safety and job performance. One thing that helped me was getting a brief letter from my insurance company acknowledging that proper eye protection is recommended for marine work - it adds another layer of documentation showing these aren't just personal preferences but legitimate business necessities.
