Because soon BIR will start cracking down all those homebase workers with unexplained wealth that didnt pay any taxes or submit their yearly ITR. Your deadline is April 15, 2019 for 2018 ITR.
Thats what ive bee thinking recently, its sooner or later they will have to catch up to us. I may self have an unexplained wealth which my neighbors says "where did he get the money from to buy those things".
Anyways, ill just do what i usually do. Thanks for the heads up.
