Do tax write-offs mean you get free stuff or money back?
A tax write-off reduces your taxable income rather than acting as a dollar-for-dollar reimbursement on what you spend. This misconception leads people to believe that business purchases are entirely free or covered by the government, missing the reality that you still pay for the item with your own money while only saving a fraction on your tax bill.
