From April to December 2011, my boss hired me as an assistant in her personal capacity. We had no formal/written arrangements /contract whatsoever. I was not required to pay PhilHealth and SSS contributions and she did not require me to have a TIN number. She gave me an allowance of P18,000/month. Is this allowance tax exempted or do I have to pay tax for this? If I have to pay tax for it, how do I compute the tax due plus penalties if I intend to file it this year? Also, do I really have to supply BIR my former boss' TIN number in the form or is her full name sufficient? Am I the only one liable or does my former boss have liability as well?
Thanks for your help and looking forward to your response.
