If you are requesting a  2018 or 2019 Report for “STATE” Taxes, Amendments or special circumstances please click here.

By logging into our site, you are acknowledging that our report now comes “AS IS”.  Because of the varied rules on state taxes and small business expenses etc., we no longer provide audit support other than to the extent of our calculations were correct.   Because of the new tax complexities, we do not provide instructions for how to use our calculation and recommend hiring a knowledgeable tax consultant to assist you.

It will be up to each individual to make sure that they fall under those exceptions in the IRS Tax Reform ruling.  For a more detailed description of the new Tax Reform please visit  www.IRS.gov.  With that being said Pro-Diem, Inc. will not be able to process your 2018 “Federal” expense report.  We thank you for your loyalty, allowing us to assist you over the years.  We will continue to look for solutions and pursue other ways we can help you.  Be sure to check our website for any updates as we will be posting any further information there.

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

Don’t give up your hard earned tax break! If you are able to itemize on your State taxes, we can help you save on your tax bill by calculating 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.

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 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.  If you are in audit for a previous year (2017 and prior) and need your per diem calculated correctly by us for your audit along with audit support, 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.

We understand each of the different airline’s 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.
