Example
I am a commissioned sales employee.
This year I incur the following work expenses, pro-rated where appropriate:
- $25,000 car and travel expenses (other than financing charges and tax depreciation)
- $4,000 home office supplies
- $8,000 advertising and promotion
- $3,000 property tax and home insurance
These expenses total $40,000.
So if my commission income for the year is more than the $25,000 car and travel expenses, I would claim as many of the deductions as possible, up to my commission income.
But if commission income was, say $23,000, I would claim the $25,000 car and travel expenses, because otherwise I would be limited to the $23,000 commission income.
