self-employed, travel ~100-days/year US & international since 1989;
have always deducted actual expenses, saved receipts, etc.
but my expenses almost always less than current per diem + M&IE;
will be calling IRS to ask questions, but seeking comments:
1. IRS allows self-employed to use Per Diem + M&IE rates
& no receipts required, right? (according to tax guide just read)
2. if I know in advance that Per Diem + M&IE rates are higher
that what I typically spend (especially due to points-miles), am
I not allowed to do so as it is tax cheating?
3. ground transport at destination is included in M&IE, but
what about flights to-from destinations -- can they be a
separate actual expense with receipts?
4. if I have always deducted actual expenses, can I switch to
Per Diem + M&IE for 2019 taxes?
Any other comments-advice appreciated. ^ ^ ^
