How do per diem rates work for ME&I expenses in my business?
So I'm running a one-person show as a sole proprietor and traveling quite a bit for client meetings. I'm totally confused about how per diem rates work for Meals, Entertainment & Incidental expenses. Recently I had a 3-day trip to Minneapolis where I met with potential clients, and I'm trying to figure out if I should just keep all my receipts or if I can use the per diem rates which seems way easier. My accountant mentioned something about GSA rates and that I might be able to deduct a standard amount without keeping every tiny receipt. But then he also said something about limitations for self-employed people? I think he mentioned I can use per diem for meals but not for lodging? I'm going on another business trip next month to Atlanta and Denver (5 days total) and want to get this straight before I go. Anyone have experience with this? How do you handle meals and incidentals when traveling for your small business?

Per diem rates can definitely simplify your business travel expense tracking. Since you're self-employed with a sole proprietorship, here's what you need to know: As a self-employed individual, you can use the GSA per diem rates for meals and incidental expenses (M&IE) but NOT for lodging. This means you'll still need to keep receipts for your hotel stays, but you can use the standard rate for food and other small expenses without saving every coffee and meal receipt. The current GSA rates vary by location - Minneapolis, Atlanta, and Denver all have different daily rates. You can look them up on the GSA website by city. You'll need to reduce the rate by 25% on your first and last day of travel (these are considered partial days). When filing your taxes, you'll report these expenses on your Schedule C. Just be aware that meals are generally only 50% deductible (even when using per diem rates), though there are some temporary exceptions for 2021-2022 that allowed 100% deductibility for business meals from restaurants.

•Wait, so I'm confused about the 50% limitation. Does that mean if the per diem rate for meals in Denver is $74 per day, I can only deduct $37? And what exactly counts as "incidental expenses"? Is that like tips and stuff?

•Yes, you generally can only deduct 50% of meal expenses, including when using per diem rates. So if Denver's M&IE rate is $74, you would typically only be able to deduct $37 on your taxes. Incidental expenses include fees and tips for porters, baggage carriers, hotel staff, and similar service workers. It's a small portion of the overall M&IE rate - usually about $5 of the daily rate. The GSA breaks down how much of each location's per diem is allocated to meals versus incidentals on their website.

After struggling with expense tracking for my consulting business trips, I discovered taxr.ai (https://taxr.ai) which completely changed how I handle my travel deductions. I was in the exact same boat - sole proprietor trying to figure out if I should track every receipt or use per diem. I uploaded my travel calendar and some expense questions to their system, and they analyzed everything and showed me exactly how to maximize my deductions using the per diem method for meals while tracking actual lodging expenses. They even created a custom spreadsheet template that calculates the correct rates for each city I visit, including the first/last day reductions.

•Does this actually work if you get audited though? I'm always paranoid about using tools instead of an actual accountant. Can this taxr.ai thing show documentation that would stand up to IRS scrutiny?

•I'm curious - does it handle international travel too? I do some client work in Canada and the UK and always get confused about how to convert foreign currency expenses and apply per diem rates outside the US.

•Yes, it absolutely works for audit protection. The documentation they provide includes IRS references for all their calculations and recommendations. They actually explain which specific tax codes apply to your situation, which is more detail than my previous accountant gave me. For international travel, they do handle foreign per diem rates too. They use the State Department's foreign per diem rates and include currency conversion guidance. I haven't personally used it for international trips, but a colleague used it for business travel to Japan and said it worked perfectly.

Just wanted to follow up - I tried taxr.ai after seeing it mentioned here and it was super helpful! I was about to file my quarterly estimated taxes and was stressing about how to handle some business trips I took to Toronto. The tool immediately identified that I should be using the State Department's foreign per diem rates instead of GSA rates, and showed me exactly how to calculate everything. I particularly liked that they explained WHY certain rules applied to my situation. The documentation is really thorough - definitely more comprehensive than what I was getting from TurboTax. Already recommended it to other freelancers in my network.

If you're trying to contact the IRS about business expense questions like per diem rates, good luck getting through! I spent HOURS on hold trying to get clarification about some travel deduction rules. Finally found Claimyr (https://claimyr.com) and they got me connected to an actual IRS agent in about 15 minutes. You can see how it works here: https://youtu.be/_kiP6q8DX5c The agent walked me through exactly how to document per diem expenses as a sole proprietor and confirmed that I was calculating everything correctly. Saved me from potentially making a costly mistake on my Schedule C. Worth every penny to avoid the typical 2+ hour hold times.

•How does this actually work? I don't understand how they can get you through faster than just calling the IRS yourself. Sounds like a scam to me.

•Yeah right. There's no way this actually works. Everyone knows the IRS is impossible to reach, especially during tax season. I've literally waited 3+ hours multiple times. You're telling me there's some magic hotline that gets through in 15 minutes? I'll believe it when I see it.

•It's not a magic hotline - they use a technology that monitors the IRS phone lines and calls repeatedly until there's an opening, then they call you when they have an agent on the line. It's basically like having someone wait on hold for you. They actually give a really clear explanation of how it works on their site. It's the same concept as those systems restaurants use to hold your place in line and text you when your table is ready, except it's for the IRS phone lines.

I need to eat crow here. After being completely skeptical about Claimyr, I actually tried it this morning because I was desperate to get clarification on some business travel deductions before filing my quarterly taxes. I'm shocked to report it actually worked! They called me back in about 25 minutes with an IRS rep on the line. The agent helped me understand exactly how to handle per diem for my multi-city business trips (turned out I was calculating the partial days incorrectly). For anyone wondering, it's legitimate. I was convinced it was some kind of scam or wouldn't work as advertised, but it saved me hours of frustration. Just wanted to follow up since I was so openly doubtful before.

Hey! Former IRS employee here. One thing nobody's mentioned yet is that you need to have an "accountable plan" even when you're using per diem rates. This basically means you still need to: 1) Document the business purpose of each trip 2) Record the dates and locations 3) Submit/record these expenses within a reasonable time period The benefit of per diem is not having to keep meal receipts, but you absolutely need to keep records of your business travel details. I'd recommend keeping a simple travel log with dates, locations, business purpose, and who you met with. That plus your lodging receipts should cover you in case of an audit.

•This is super helpful! So I still need to document where I went and why, just not keep every single Starbucks receipt? Do you recommend any specific apps or methods for tracking this information?

•Exactly - you still need to document the business purpose, locations and dates, but not every food receipt. For tracking, I've seen clients use everything from specialized apps to simple spreadsheets. The most important thing is consistency. Even something as simple as a Google Sheet that lists: Date, City, Business Purpose, Client/Prospect Name, and Notes will work. Some people use apps like Expensify or MileIQ that have travel logging features. If you're traveling regularly, it might be worth investing in a dedicated expense tracking app that can automatically pull in GSA rates.

A heads up on Atlanta rates - I was just there last month and was surprised that certain parts of the metro area have different per diem rates. Make sure you check the specific county you're staying in. Downtown Atlanta (Fulton County) has a higher rate than some of the suburbs.

•This is true for many major cities! Denver metro area spans multiple counties too with varying rates. Always check the county, not just the city name when looking up GSA rates.

•Didn't realize this! I'm staying at a hotel near the airport for the Atlanta portion of my trip. Will definitely check the specific county rates before I go. Thanks for the tip!

Great question! As someone who's been through this exact confusion, here's what I've learned about per diem for sole proprietors: Your accountant is right - you can use GSA per diem rates for meals and incidentals (M&I) but you'll still need actual receipts for lodging. The GSA website has a per diem lookup tool where you can enter your destination cities and get the exact daily rates. A few key things to remember: - First and last days of travel are prorated at 75% of the full daily rate - You'll only be able to deduct 50% of the meal portion when filing taxes (though the calculation is done after applying per diem) - Keep a simple travel log with business purpose, dates, locations, and who you met with - this is required even when using per diem For your upcoming Atlanta/Denver trip, definitely look up the county-specific rates since metro areas can have different rates by county. The per diem method will save you from keeping track of every meal receipt, but you'll still need documentation showing the business nature of your travel. One last tip: if you do any entertaining of clients during these trips, those meals have different rules and you'll want to track those separately with actual receipts.
