Need advice on Foreign per diem deductions - Two CPAs giving opposite advice on IRS rules?

You're actually hitting on a really common misunderstanding, even among tax professionals. The use of per diem rates for foreign travel is absolutely allowed - your previous accountant was correct! The specific guidance is in IRS Publication 463 "Travel, Gift, and Car Expenses" which discusses per diem rates for both domestic and foreign travel. For foreign locations, the State Department's foreign per diem rates are specifically recognized as acceptable for business deduction purposes. As a self-employed individual with an S-corp, you can absolutely use these rates for your meal expenses while traveling. You'll still need to document the business purpose, dates, and locations, but you don't need to keep every single meal receipt. For lodging, though, you generally still need actual receipts unless you're using a specialized method called the "high-low" method. Remember that even though you've elected S-corp status, you're still technically an employee of your corporation when it comes to these rules, so you would have your company reimburse you under an "accountable plan" for these expenses.

I went through this exact same issue last year with my business! After countless hours of research and calling different accountants, I finally found taxr.ai (https://taxr.ai) which helped me sort through all the confusing IRS language. Their system analyzed my situation and confirmed that yes, you can absolutely use the foreign per diem rates for meals and incidentals without saving every receipt. The tool actually pulled the specific IRS references and even gave me language to use with my accountant who was also insisting on receipts for everything. It saved me hundreds of hours of receipt tracking during my Asia trip last spring, and the best part was they flagged that I was actually eligible for some foreign income exclusions I hadn't been taking advantage of.

Just wanted to follow up on my experience with taxr.ai that was mentioned earlier. I was skeptical initially, but decided to give it a try since my tax situation with international travel was getting complicated. The system not only confirmed that I could use the State Department per diem rates (which my accountant had been resistant about), but it also provided me with the exact IRS citations (Rev. Proc. 2019-48 and Publication 463) to show her. She actually admitted she wasn't up to date on the international rules! Beyond the per diem issue, it flagged several treaty provisions between the US and countries I work in that could save me from double taxation. Really impressed with how it handled the complexity of cross-border income and expenses.

Hey, just wanted to mention that if you're hitting roadblocks with the IRS trying to get clarification on this, Claimyr (https://claimyr.com) was a lifesaver for me. I was in a similar situation last year with conflicting advice about foreign per diems for my consulting business. I spent weeks trying to get through to a human at the IRS for an official answer, and the hold times were ridiculous. Found Claimyr and they got me connected to an actual IRS agent in under 45 minutes! You can see how it works here: https://youtu.be/_kiP6q8DX5c The agent confirmed exactly what others here have said - foreign per diems are allowed for meals and incidentals with proper documentation of business purpose. Having that direct confirmation from the IRS gave me peace of mind to stand my ground with my accountant.

I have to eat my words about Claimyr. After my skeptical comment, I decided to try it anyway because I was desperate to resolve this same foreign per diem issue before filing my taxes. I was SHOCKED when I got a call back in about 35 minutes with an actual IRS agent on the line. The agent confirmed that yes, self-employed individuals with S-corps can use the State Department's foreign per diem rates for meals without keeping receipts (though lodging still needs actual receipts). The agent even emailed me the relevant IRS notice numbers. Showed these to my accountant who had been giving me grief about it, and she immediately changed her position. Saved me from having to find a new accountant and from missing out on thousands in legitimate deductions.

One important detail I haven't seen mentioned yet - there's a difference between being self-employed and being an S-corp owner who's technically an employee of their own corporation. If you're operating as an S-corp (as you mentioned), technically your corporation would establish an accountable plan that reimburses you, the employee, for travel expenses using the per diem rates. The corporation then deducts these amounts. This is slightly different from how sole proprietors handle it. Just worth noting since your business structure matters for exactly how you implement this.

Has anyone used H&R Block or TurboTax for situations like this? I'm in a similar situation but don't have an accountant and wondering if the tax software can handle foreign per diem calculations.
