3D rendering of a melanocyte. Through a process called melanogenesis, these cells produce melanin, which is a pigment found in the skin, eyes, and hair. This melanogenesis leads to a long-lasting pigmentation, which is in contrast to the pigmentation that originates from oxidation of already-existing melanin.
Example 1. You spend $200 for a business-related meal. If $110 of that amount is not allowable because it is lavish and extravagant, the remaining $90 is subject to the 50% limit. Your deduction cannot be more than $45 (50% Ã $90).
You can deduct employee expenses as well (as long as your employer didn't reimburse you for them), the cost of insurance to your business, and health insurance premiums if you are self-employed. The cost of personal liability insurance, in most cases, is not deductible.
