Why is EZPerDiem giving me a deduction for M&IE on my last day at my domicile?

Once you are on a work-related trip with overnight travel, you are entitled to write off M&IE expenses for every day you work during that trip.  This includes the last day of the trip.  Your last day will always terminate at your domicile.  The per diem rate used for the M&IE calculation on the last day of a trip is actually the rate for the preceding overnight.  This is described in IRS Publication 463.

Partial days are prorated at 75% by default; however, you can change them to 100% on the Tools & Settings page if you wish.  Please reference IRS Publication 463 before changing the proration amount.
