Hello po, i just wanted to ask a question. I was working in a hotel before through an agency years ago (before covid) when covid hit, wala na pong work and di na ako bumalik sa hotel. I have my TIN from before and now im working as a freelance. Question is pano po ako mag file for ITR? Do i need to update my TIN? And meron po ba akong penalties? Thank you po
