CAN YOU WRITE OFF MORTGAGE INTEREST ON HOME OFFICE USE ON THE MISC DEDUCTION ABOVE 2% FOR CALIFORNIA

[GILBERT73]

ON THE CA SIDE IS MORTGAGE INTEREST AND REAL ESTATE TAXES ALLOWED AS A DEDUCTION ON THE HOME OFFICE USE WORKSHEET ?

If the employee qualifies for OIH as part of misc itemized deductions, yes, Mort Int and Prop Tax get included as well as Homeowners Ins, and utilities, etc.
You'll complete the OIH info on the federal side at the bottom of Sch A, Misc Itemized quick zoom button (OIH is kind of buried in there) and it will transfer over to CA.
