I use simplified method for calculating my deduction for home office use for business. In the simplified method worksheet, line A is showing $0. Something is wrong. I can't believe that the gross income limitation would ever be $0 unless you did not make any money with your business. In past years, it usually had my gross profit from my 1040.
TT is not allowing me to overwrite that $0 with my gross income from my business. It also won't allow me to manually enter the $ amount from line F in line 30 of Schedule C. How can I get my $750 deduction for my business use of home?
The number for line A of the Simplified Method Worksheet comes from the Form 8829 worksheet, Part II, line 9.
If you check that section you will see several adjustments to gross income, including percentage of use, related income and expenses.
There are several reasons why you would end with a zero on line 9, but the most common one is that your self-employment expenses are equal to or more than your gross self-employment income.
Please take a look at Part II of the Form 8829 worksheet and if you have more questions, please respond back to this thread.
