A tax deduction just lowers the income you pay tax on. The rule of thumb: if an expense is ordinary (normal for your work) and necessary (helpful to your business), it is usually deductible. Keep a receipt, note the business reason, and you are most of the way there. Tap any deduction below to see the details.
