4 types of travel meal expenses...how do I file these?

Hey all, thanks in advance for help.

 

I travel for work, mostly working for musicians at concerts. I'll leave home and sometimes not come back for 6 weeks. I'd like to take advantage of M&IE per diem rates per city as I often travel to expensive places.

 

My question is about meals. How would I expense these scenarios? It's all 1099 work.

 

Contract 1: I pay for restaurants 3 meals a day, contract pays no per diem (I assume I can deduct 100% of GSA M&IE rate, yeah?

 

Contract 2: I pay for restaurants 3 meals a day, contract pays $25 per diem, but it's not added to my 1099

 

Contract 3: I pay for restaurants 3 meals a day, contract pays $25 per diem, but it IS added to my 1099

 

Contract 4: Supplies 3 meals a day (catering), but occasionally I still go out to restaurants for a meal or two a day.

 

Thanks for any help!
