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 calculation 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 reciepts, an allowance for meals & incidental expenses up to a specified maximum rate for each city per day. The international rates are often 2-4 times more than what you were actually paid in per diem. Because it is almost impossible to keep receipts, using this method is the best way for pilots and flights attendants 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 & 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 free audit support if you used our per diem calculation on your original tax form because we know we are calculating your exact allowance. No cheesy online lookup of just dates and layovers, which can possibly short you hundreds of dollars of your per diem in the long run. We use your flight times so 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 when using our numbers on your original tax filing, if needed. If you are in audit and need your per diem calculated correctly by us for your audit, we charge an additional $500.00 per tax year and accept requests on a case by case basis as time allows. It is a time consuming process to help correct other per diem companies’ mistakes. Rest easy knowing your report was done correctly and has the backing from a legitimate company and not a fly by night internet app.


If you have questions we are here to talk
Call us at (817) 421-8389

We understand each of the different airlines inherent issues and make sure that your per diem report is correct. We understand time conversions between Local and Zulu, daylight savings times, date line issues, flight rules, and partial day rules. We are knowledgeable on training issues and rules regarding ground times and layovers which are additional considerations that require expertise when calculating these expenses. We will even call you if we think you are missing information because we care about doing your per diem report correctly.

In order to continue providing high quality service, we are changing our procedures for clients who come to us in audit when we did not originally calculate their per diem for that tax year. We will now charge a minimum fee of $500.00, to calculate their per diem and provide audit support in addition to our standard processing fee. It is our goal at Pro-Diem to provide you not only with a correct per diem calculation but also solid information about what you can claim and how to fill our your tax form for each year correctlythe first time.

If we provided your per diem calculation on your original tax form, there will be no additional charge for audit support.
