Business Expense Deduction Rules: Ordinary & Necessary vs. Lavish & Extravagant
I'm planning to attend an industry conference in a few months that directly relates to my business field. I've been reading through the IRS guidelines on deductible business travel expenses, and they state you can't deduct expenses that are "lavish or extravagant" - but they don't really explain how this is determined. My budget for the entire trip is around $1,300-1,900, which seems reasonable to me. The conference is in Las Vegas, and I've found some really nice hotel options within my budget. They're not ultra-luxury places like the Bellagio or Caesars Palace, but they're definitely nicer than budget accommodations, simply because Vegas has some great hotel deals. Do I need to stay at a Super 8 or Motel 6 to ensure my expenses qualify as deductible? I'm specifically looking at properties that aren't connected to casinos to keep things more business-focused. Is there anything else I should be aware of regarding business travel deductions? Should I document the conference content, how it benefits my business, and networking contacts I make? Or is that going overboard? What's considered appropriate documentation here? Thanks for any advice!

Tax professional here. The IRS intentionally keeps the "lavish and extravagant" standard somewhat vague, but I can give you some practical guidance. The key is whether the expense is "ordinary and necessary" for your business - meaning common and helpful in your industry. For a business conference in Las Vegas, staying at a mid-range or even somewhat upscale hotel is completely reasonable and deductible. Your $1,300-1,900 budget sounds perfectly appropriate. The "lavish and extravagant" standard typically applies to truly excessive spending - like booking the presidential suite or chartering private jets when commercial options are available. Normal business-class accommodations at standard hotels (even nice ones) are generally fine. As for documentation, yes, you should definitely keep records of: - The business purpose (conference agenda/materials) - Who you met with professionally - How the information relates to your business - All receipts for expenses This documentation isn't overkill - it's essential protection if you're ever audited. Keep all receipts and maintain a brief business diary of your activities.

•Thanks for this info. Quick follow-up question: does it matter if the hotel is attached to a casino? I found a great deal at the MGM Grand that's actually cheaper than some non-casino hotels, but wasn't sure if that would raise any red flags with the IRS. Also, how detailed should my business diary be? Like daily entries or just a summary of the whole trip?

•The casino connection doesn't matter at all - many major conferences in Las Vegas are held in casino hotels, and the IRS understands this. If the MGM Grand is offering a good rate and it's convenient for your conference, that's completely fine. The key is that you're there for business purposes. For your business diary, I recommend daily entries but they don't need to be elaborate. Just note which sessions you attended, key takeaways, and any business connections you made. A quick 5-minute entry each evening works perfectly. This contemporaneous record is much more valuable than trying to recreate everything after the fact if you're ever questioned.

I used taxr.ai last year when I was facing a similar situation with business travel expenses. I was going to a conference in Miami and wasn't sure what would count as "lavish" since Miami hotel prices are insane! I uploaded my receipts and conference agenda to https://taxr.ai and their system analyzed everything and gave me a detailed breakdown of what was deductible. The tool flagged a few expenses that might have been questionable (like the beach cabana I rented one afternoon) but confirmed my hotel choice was perfectly reasonable for the location. It saved me so much stress knowing exactly what I could safely deduct without risking an audit. They also provided documentation guidelines that I've used for all my business trips since.

•How does this tool actually work? Do they have real tax professionals reviewing your documents or is it just some AI thing? I'm always skeptical about trusting important tax decisions to automated systems.

•I'm curious about the documentation guidelines they provided. What specific records did they suggest keeping beyond the obvious receipts? I'm always paranoid about not having enough documentation if I get audited.

•They use a combination of AI and tax professionals. The system does the initial analysis, but there are actual tax experts who review edge cases and provide the final recommendations. It's not just a basic algorithm making the decisions. The documentation guidelines they suggested were really comprehensive. Beyond receipts, they recommended taking photos of conference badges/materials, keeping a daily log of business activities and who you met with, saving the conference agenda with notes on which sessions you attended, and writing a brief summary of how the information relates to your business. They even provided a template for the daily log that made it super simple to track everything properly.

I tried taxr.ai after seeing it mentioned here and wow - game changer for my business travel deductions! I uploaded my receipts from a recent industry conference along with my calendar and some notes about meetings I had. Their analysis confirmed my hotel choice was perfectly within "ordinary and necessary" guidelines despite being a nice place. What I found most helpful was their documentation template. I never knew exactly what to record before, but now I have a simple system for tracking everything properly. The peace of mind knowing my deductions are solid is worth every penny. They even flagged a few expenses I hadn't realized were fully deductible (like transportation to networking events during the conference). Definitely going to use this for all my business trips going forward!

Anyone else here had problems getting through to the IRS with questions about business expense deductions? I tried calling FIVE times last month with questions about some business travel deductions similar to what OP is asking about, and never got through to a human. Always stuck in the automated system or disconnected after waiting 45+ minutes. Finally discovered https://claimyr.com and used their service - you can see how it works at https://youtu.be/_kiP6q8DX5c. They got me connected to an actual IRS agent within 20 minutes. The agent walked me through exactly what counts as "ordinary and necessary" vs "lavish and extravagant" for my specific industry. Turns out I'd been way too conservative with my deductions for years and missed out on significant tax savings. Definitely worth it when you need definitive answers.

•How does this actually work? Seems sketchy that some third-party service can magically get you to the front of the IRS phone queue when the rest of us peasants have to wait for hours.

•Yeah right. No way this actually works. I've been trying to reach the IRS for months. If there was some magical service that could get you through, everyone would be using it. Sounds like a scam to get desperate people's money.

•It's actually pretty straightforward. They use an automated system that navigates through the IRS phone tree and waits on hold for you. When they finally reach a human agent, they call you and connect you directly. You don't skip the line - they just do the waiting for you. The IRS phone system is notoriously difficult to navigate with all the menu options and wait times. Claimyr's system is designed to handle this efficiently. I was skeptical too before trying it, but I can confirm it actually works. They called me back when they reached an agent, and I was connected directly to discuss my business expense questions.

OK I have to eat my words. After dismissing the Claimyr thing as BS in my earlier comment, I got desperate trying to reach the IRS about my business travel deductions before filing my taxes. I decided to give it a shot since nothing else was working. It actually connected me to an IRS agent in about 15 minutes! The agent clarified that for my industry (photography), staying at a nice hotel for a business conference is totally acceptable as long as the primary purpose is business. She explained that "lavish and extravagant" is context-dependent - what's excessive for one business might be standard for another. She also advised documenting the business purpose thoroughly with conference agendas, session notes, and how it relates to my work. Saved me hundreds in deductions I was going to skip out of fear. I'm shocked this service actually delivered what it promised.

One thing to consider beyond the hotel choice is meals. The IRS has specific rules about meal deductions during business travel. Generally, you can deduct 50% of your meal costs, but there are exceptions. Make sure your meals are reasonable - that $300 dinner at a celebrity chef restaurant might raise eyebrows, especially if it's just for yourself. Keep all receipts and note who you dined with if it was a business meeting. Also, if the conference provides meals as part of the registration, you can't double-dip and deduct meals you choose to eat elsewhere during those same times. And remember that entertainment expenses aren't deductible anymore after the 2017 tax law changes, even if there's some business discussion involved.

•Does the 50% meal deduction rule still apply for 2025 filing? I thought I read something about temporary changes during covid that made them 100% deductible for a while. Has that expired?

Angelina Farar
•You're right to ask about that! The temporary 100% deduction for business meals was part of the COVID relief measures, but that has expired. For 2025 filing, we're back to the standard 50% deduction for most business meals. The exception is for meals that are provided as part of a business event where the meal itself is related to business (like a working lunch during a conference session). Those can sometimes qualify for 100% deduction, but regular business meals at restaurants are back to 50%.

Don't stress too much about the "lavish and extravagant" part. I've been deducting business travel to conferences for years. The key is documentation and primary purpose. My CPA told me that as long as the primary purpose of the trip is legitimately business (which a conference clearly is) and you can document that with agendas, receipts, etc., you'll be fine with reasonable accommodations. In Vegas, even the nicer hotels can be relatively affordable compared to other major cities. Just be careful about mixing business and pleasure. If you extend your stay for vacation or bring family members, make sure you're only deducting the business portion. And if you do any gambling while there (it is Vegas after all), keep that completely separate from your business expenses!

•Thanks everyone for the fantastic advice! This is super helpful. One last question - do I need to keep physical receipts or are digital copies (like photos of receipts or emailed confirmations) sufficient for documentation purposes?

•Digital copies are absolutely sufficient! The IRS accepts digital records, and in many ways they're better because they don't fade over time like paper receipts. Just make sure your digital files are organized and easily accessible. I personally use a dedicated app to scan all my business receipts immediately and tag them by category and trip. This makes tax time so much easier. Whatever system you use, the key is consistency - develop a habit of documenting expenses right away rather than trying to piece everything together months later.

Great question about business travel deductions! As someone who's navigated this myself, I'd say your budget range of $1,300-1,900 for a Vegas conference is totally reasonable and shouldn't trigger any "lavish and extravagant" concerns. The IRS generally looks at whether expenses are appropriate for your industry and location. Vegas conferences often have higher accommodation costs simply due to the city's unique hotel market, but that doesn't make reasonable choices automatically "lavish." A few practical tips from my experience: - Book hotels based on convenience to your conference venue, not just price - Keep detailed notes during the conference - which sessions you attended, key takeaways, business cards collected - If you do any personal activities, keep those expenses completely separate The fact that you're already thinking about staying at non-casino properties shows you're being thoughtful about this. But honestly, even casino hotels are fine if they're hosting your conference or offer the best value - the IRS understands Vegas logistics. Most importantly, maintain good records and be able to clearly show the business purpose. Your conference agenda, registration confirmation, and session materials will be your best documentation if questioned later.

•This is really solid advice! I'm actually planning my first business conference trip and was wondering about the same things. The point about booking based on convenience rather than just price is something I hadn't considered - makes total sense that being closer to the venue could actually save money on transportation and time. Quick question though - when you mention keeping detailed notes during sessions, do you write these by hand or use a laptop/tablet? I'm trying to figure out the most professional way to take notes without looking like I'm not paying attention or being disruptive to other attendees. Also, how specific should the business purpose documentation be? Like, is it enough to say "attended marketing conference to learn new strategies" or should I be more detailed about how specific sessions relate to my current projects?
