The #1 choice of Crew Members for Per Diem Calculation!

Don’t give up your hard earned tax break! If you itemize on your taxes we can help you save hundreds or even thousands off your tax bill by using our service to calculate your travel expenses correctly.

If you are a pilot or flight attendant for a major airline and paid a per diem, your allowable meal and incidental expenses were probably much greater than the per diem you were paid. The IRS has determined, through Federal Revenue Procedures, that persons in the aviation industry are allowed to deduct, without receipts, an allowance for meals and incidental expenses up to a specified maximum rate for each city per day.  The international rates are often 2-4 times higher than you were actually paid in per diem.  Because it is almost impossible to keep receipts, using this method is the best way for a pilot and or a flight attendant to determine how much they can deduct for their per diem allowance.

We make it easy!

Using our sophisticated computer program we will calculate your maximum allowed meal and incidental expenses (per diem amount) and supply you with a detailed report indicating, leg by leg, exactly what you are allowed to claim on your taxes. We DO give audit support free if you used our per diem calculation on your original tax form because we know we are really calculating your exact allowance. We don’t do a cheesy online lookup of just your dates and layovers, causing you to be shorted possibly hundreds of dollars of your per diem in the long run. We use your flight times so that we can stretch out your actual allowance to give you the most you can claim to the penny!  

Our fee is only $59.00 and includes free audit support if ever needed when using our numbers on your original tax filing.   If you are in audit and need your per diem calculated correctly by us for your audit, we charge an additional $500.00 per year and take only on a case by case basis as time allows.   It is a time consuming process to help correct other per diem companies mistakes.   It pays to have it done right the first time!   You will rest easy knowing it was done correctly and has the backing from a legitimate company and not by a fly by night internet app.

If you have questions. we are here to talk to and ask questions.
