Taxation
The difference that decides whether you need to register.
Many doctors think that because a hospital engaged them, they are employed. Often they are not. Being engaged as a professional, or consultant, is different from being employed. That difference decides whether you need to register with the BIR and file your own returns. Here is how to tell which one you are.
Your payslip shows SSS or GSIS, PhilHealth, and Pag-IBIG, and you get a Form 2316 at year end.
There are no such benefits, and you receive a Form 2307 for the tax withheld on your fees.
These are the everyday signs. Whether you are truly employed or engaged as a professional comes down to your actual working relationship, not the benefits alone.
Many doctors are both at once, employed at one hospital and engaged as a professional elsewhere. That is a mixed income earner, which is perfectly normal. See Mixed income: employed doctor with private practice.
If you are purely employed, your employer takes care of your tax, and there is nothing for you to register. But if any part of your income comes from being engaged as a professional, that part is yours. You register with the BIR, file your own returns, and issue a service invoice for your fees. Getting this right keeps you compliant and saves you from problems later.
