If you're a professional, same lang ang treatment ng deduction tulad sa IT pro. For ex., you can claim a portion of your household expense (electricity, rent/mortgate, etc.) if you are working sa bahay, but you need to keep a detailed daily logbook of your work activity plus dapat walang tao sa bahay at the time you are working.
Another ex. for a deductible expense is magazine subscription, pero don't claim your fhm subscription as a deduction 🙂 dapat related sa profession mu.
